Let's say you create a wizard in an HTML form. One button goes back, and one goes forward. Since the back button appears first in the markup when you press Enter, it will use that button to submit the form.
Example:
<form>
<!-- Put your cursor in this field and press Enter -->
<input type="text" name="field1" />
<!-- This is the button that will submit -->
<input type="submit" name="prev" value="Previous Page" />
<!-- But this is the button that I WANT to submit -->
<input type="submit" name="next" value="Next Page" />
</form>
I would like to get to decide which button is used to submit the form when a user presses Enter. That way, when you press Enter the wizard will move to the next page, not the previous. Do you have to use tabindex to do this?
I'm just doing the trick of floating the buttons to the right.
This way the Prev button is left of the Next button, but the Next comes first in the HTML structure:
.f {
float: right;
}
.clr {
clear: both;
}
<form action="action" method="get">
<input type="text" name="abc">
<div id="buttons">
<input type="submit" class="f" name="next" value="Next">
<input type="submit" class="f" name="prev" value="Prev">
<div class="clr"></div><!-- This div prevents later elements from floating with the buttons. Keeps them 'inside' div#buttons -->
</div>
</form>
Benefits over other suggestions: no JavaScript code, accessible, and both buttons remain type="submit".
Change the previous button type into a button like this:
<input type="button" name="prev" value="Previous Page" />
Now the Next button would be the default, plus you could also add the default attribute to it so that your browser will highlight it like so:
<input type="submit" name="next" value="Next Page" default />
Give your submit buttons the same name like this:
<input type="submit" name="submitButton" value="Previous Page" />
<input type="submit" name="submitButton" value="Next Page" />
When the user presses Enter and the request goes to the server, you can check the value for submitButton on your server-side code which contains a collection of form name/value pairs. For example, in ASP Classic:
If Request.Form("submitButton") = "Previous Page" Then
' Code for the previous page
ElseIf Request.Form("submitButton") = "Next Page" Then
' Code for the next page
End If
Reference: Using multiple submit buttons on a single form
If the fact that the first button is used by default is consistent across browsers, put them the right way around in the source code, and then use CSS to switch their apparent positions.
float them left and right to switch them around visually, for example.
Sometimes the provided solution by palotasb is not sufficient. There are use cases where for example a "Filter" submits button is placed above buttons like "Next and Previous". I found a workaround for this: copy the submit button which needs to act as the default submit button in a hidden div and place it inside the form above any other submit button.
Technically it will be submitted by a different button when pressing Enter than when clicking on the visible Next button. But since the name and value are the same, there's no difference in the result.
<html>
<head>
<style>
div.defaultsubmitbutton {
display: none;
}
</style>
</head>
<body>
<form action="action" method="get">
<div class="defaultsubmitbutton">
<input type="submit" name="next" value="Next">
</div>
<p><input type="text" name="filter"><input type="submit" value="Filter"></p>
<p>Filtered results</p>
<input type="radio" name="choice" value="1">Filtered result 1
<input type="radio" name="choice" value="2">Filtered result 2
<input type="radio" name="choice" value="3">Filtered result 3
<div>
<input type="submit" name="prev" value="Prev">
<input type="submit" name="next" value="Next">
</div>
</form>
</body>
</html>
This cannot be done with pure HTML. You must rely on JavaScript for this trick.
However, if you place two forms on the HTML page you can do this.
Form1 would have the previous button.
Form2 would have any user inputs + the next button.
When the user presses Enter in Form2, the Next submit button would fire.
I would use JavaScript to submit the form. The function would be triggered by the OnKeyPress event of the form element and would detect whether the Enter key was selected. If this is the case, it will submit the form.
Here are two pages that give techniques on how to do this: 1, 2. Based on these, here is an example of usage (based on here):
<SCRIPT TYPE="text/javascript">//<!--
function submitenter(myfield,e) {
var keycode;
if (window.event) {
keycode = window.event.keyCode;
} else if (e) {
keycode = e.which;
} else {
return true;
}
if (keycode == 13) {
myfield.form.submit();
return false;
} else {
return true;
}
}
//--></SCRIPT>
<INPUT NAME="MyText" TYPE="Text" onKeyPress="return submitenter(this,event)" />
If you really just want it to work like an install dialog, just give focus to the "Next" button OnLoad.
That way if the user hits Return, the form submits and goes forward. If they want to go back they can hit Tab or click on the button.
You can do it with CSS.
Put the buttons in the markup with the Next button first, then the Prev button afterwards.
Then use CSS to position them to appear the way you want.
This works without JavaScript or CSS in most browsers:
<form>
<p><input type="text" name="field1" /></p>
<p><a href="previous.html">
<button type="button">Previous Page</button></a>
<button type="submit">Next Page</button></p>
</form>
Firefox, Opera, Safari, and Google Chrome all work. As always, Internet Explorer is the problem.
This version works when JavaScript is turned on:
<form>
<p><input type="text" name="field1" /></p>
<p><a href="previous.html">
<button type="button" onclick="window.location='previous.html'">Previous Page</button></a>
<button type="submit">Next Page</button></p>
</form>
So the flaw in this solution is:
Previous Page does not work if you use Internet Explorer with JavaScript off.
Mind you, the back button still works!
If you have multiple active buttons on one page then you can do something like this:
Mark the first button you want to trigger on the Enter keypress as the default button on the form. For the second button, associate it to the Backspace button on the keyboard. The Backspace eventcode is 8.
$(document).on("keydown", function(event) {
if (event.which.toString() == "8") {
var findActiveElementsClosestForm = $(document.activeElement).closest("form");
if (findActiveElementsClosestForm && findActiveElementsClosestForm.length) {
$("form#" + findActiveElementsClosestForm[0].id + " .secondary_button").trigger("click");
}
}
});
<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.min.js"></script>
<form action="action" method="get" defaultbutton="TriggerOnEnter">
<input type="submit" id="PreviousButton" name="prev" value="Prev" class="secondary_button" />
<input type="submit" id='TriggerOnEnter' name="next" value="Next" class="primary_button" />
</form>
Changing the tab order should be all it takes to accomplish this. Keep it simple.
Another simple option would be to put the back button after the submit button in the HTML code but float it to the left so it appears on the page before the submit button.

Changing the tab order should be all it takes to accomplish this. Keep it simple.
The first time I came up against this, I came up with an onclick()/JavaScript hack when choices are not prev/next that I still like for its simplicity. It goes like this:
#model myApp.Models.myModel
<script type="text/javascript">
function doOperation(op) {
document.getElementById("OperationId").innerText = op;
// you could also use Ajax to reference the element.
}
</script>
<form>
<input type="text" id = "TextFieldId" name="TextField" value="" />
<input type="hidden" id="OperationId" name="Operation" value="" />
<input type="submit" name="write" value="Write" onclick='doOperation("Write")'/>
<input type="submit" name="read" value="Read" onclick='doOperation("Read")'/>
</form>
When either submit button is clicked, it stores the desired operation in a hidden field (which is a string field included in the model the form is associated with) and submits the form to the Controller, which does all the deciding. In the Controller, you simply write:
// Do operation according to which submit button was clicked
// based on the contents of the hidden Operation field.
if (myModel.Operation == "Read")
{
// Do read logic
}
else if (myModel.Operation == "Write")
{
// Do write logic
}
else
{
// Do error logic
}
You can also tighten this up slightly using numeric operation codes to avoid the string parsing, but unless you play with enumerations, the code is less readable, modifiable, and self-documenting and the parsing is trivial, anyway.
From https://html.spec.whatwg.org/multipage/forms.html#implicit-submission
A form element's default button is the first submit button in tree
order whose form owner is that form element.
If the user agent supports letting the user submit a form implicitly
(for example, on some platforms hitting the "enter" key while a text
field is focused implicitly submits the form)...
Having the next input be type="submit" and changing the previous input to type="button" should give the desired default behavior.
<form>
<input type="text" name="field1" /> <!-- put your cursor in this field and press Enter -->
<input type="button" name="prev" value="Previous Page" /> <!-- This is the button that will submit -->
<input type="submit" name="next" value="Next Page" /> <!-- But this is the button that I WANT to submit -->
</form>
This is what I have tried out:
You need to make sure you give your buttons different names
Write an if statement that will do the required action if either button is clicked.
<form>
<input type="text" name="field1" /> <!-- Put your cursor in this field and press Enter -->
<input type="submit" name="prev" value="Previous Page" /> <!-- This is the button that will submit -->
<input type="submit" name="next" value="Next Page" /> <!-- But this is the button that I WANT to submit -->
</form>
In PHP,
if(isset($_POST['prev']))
{
header("Location: previous.html");
die();
}
if(isset($_POST['next']))
{
header("Location: next.html");
die();
}
I came across this question when trying to find an answer to basically the same thing, only with ASP.NET controls, when I figured out that the ASP button has a property called UseSubmitBehavior that allows you to set which one does the submitting.
<asp:Button runat="server" ID="SumbitButton" UseSubmitBehavior="False" Text="Submit" />
Just in case someone is looking for the ASP.NET button way to do it.
<input type="submit" name="prev" value="Previous Page">
<input type="submit" name="prev" value="Next Page">
Keep the name of all submit buttons the same: "prev".
The only difference is the value attribute with unique values. When we create the script, these unique values will help us to figure out which of the submit buttons was pressed.
And write the following coding:
btnID = ""
if Request.Form("prev") = "Previous Page" then
btnID = "1"
else if Request.Form("prev") = "Next Page" then
btnID = "2"
end if
With JavaScript (here jQuery), you can disable the prev button before submitting the form.
$('form').on('keypress', function(event) {
if (event.which == 13) {
$('input[name="prev"]').prop('type', 'button');
}
});
I solved a very similar problem in this way:
If JavaScript is enabled (in most cases nowadays) then all the submit buttons are "degraded" to buttons at page load via JavaScript (jQuery). Click events on the "degraded" button typed buttons are also handled via JavaScript.
If JavaScript is not enabled then the form is served to the browser with multiple submit buttons. In this case hitting Enter on a textfield within the form will submit the form with the first button instead of the intended default, but at least the form is still usable: you can submit with both the prev and next buttons.
Working example:
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
</head>
<body>
<form action="http://httpbin.org/post" method="post">
If JavaScript is disabled, then you CAN submit the form
with button1, button2 or button3.
If you press enter on a text field, then the form is
submitted with the first submit button.
If JavaScript is enabled, then the submit typed buttons
without the 'defaultSubmitButton' style are converted
to button typed buttons.
If you press Enter on a text field, then the form is
submitted with the only submit button
(the one with class defaultSubmitButton)
If you click on any other button in the form, then the
form is submitted with that button's value.
<br />
<input type="text" name="text1" ></input>
<button type="submit" name="action" value="button1" >button 1</button>
<br />
<input type="text" name="text2" ></input>
<button type="submit" name="action" value="button2" >button 2</button>
<br />
<input type="text" name="text3" ></input>
<button class="defaultSubmitButton" type="submit" name="action" value="button3" >default button</button>
</form>
<script>
$(document).ready(function(){
/* Change submit typed buttons without the 'defaultSubmitButton'
style to button typed buttons */
$('form button[type=submit]').not('.defaultSubmitButton').each(function(){
$(this).attr('type', 'button');
});
/* Clicking on button typed buttons results in:
1. Setting the form's submit button's value to
the clicked button's value,
2. Clicking on the form's submit button */
$('form button[type=button]').click(function( event ){
var form = event.target.closest('form');
var submit = $("button[type='submit']",form).first();
submit.val(event.target.value);
submit.click();
});
});
</script>
</body>
</html>
You can use Tabindex to solve this issue. Also changing the order of the buttons would be a more efficient way to achieve this.
Change the order of the buttons and add float values to assign them the desired position you want to show in your HTML view.
A maybe somewhat more modern approach over the CSS float method could be a solution using flexbox with the order property on the flex items. It could be something along those lines:
<div style="display: flex">
<input type="submit" name="next" value="Next Page" style="order: 1" />
<input type="submit" name="prev" value="Previous Page" style="order: 0" />
</div>
Of course it depends on your document structure whether this is a feasible approach or not, but I find flex items much easier to control than floating elements.
Instead of struggling with multiple submits, JavaScript or anything like that to do some previous/next stuff, an alternative would be to use a carousel to simulate the different pages.
Doing this :
You don't need multiple buttons, inputs or submits to do the previous/next thing, you have only one input type="submit" in only one form.
The values in the whole form are there until the form is submitted.
The user can go to any previous page and any next page flawlessly to modify the values.
Example using Bootstrap 5.0.0 :
<div id="carousel" class="carousel slide" data-ride="carousel">
<form action="index.php" method="post" class="carousel-inner">
<div class="carousel-item active">
<input type="text" name="lastname" placeholder="Lastname"/>
</div>
<div class="carousel-item">
<input type="text" name="firstname" placeholder="Firstname"/>
</div>
<div class="carousel-item">
<input type="submit" name="submit" value="Submit"/>
</div>
</form>
<a class="btn-secondary" href="#carousel" role="button" data-slide="prev">Previous page</a>
<a class="btn-primary" href="#carousel" role="button" data-slide="next">Next page</a>
</div>
I think this is an easy solution for this. Change the Previous button type to button, and add a new onclick attribute to the button with value jQuery(this).attr('type','submit');.
So, when the user clicks on the Previous button then its type will be changed to submit and the form will be submitted with the Previous button.
<form>
<!-- Put your cursor in this field and press Enter -->
<input type="text" name="field1" />
<!-- This is the button that will submit -->
<input type="button" onclick="jQuery(this).attr('type','submit');" name="prev" value="Previous Page" />
<!-- But this is the button that I WANT to submit -->
<input type="submit" name="next" value="Next Page" />
</form>
Problem
A form may have several submit buttons.
When pressing return in any input, the first submit button is used by the browser.
However, sometimes we want to use a different/later button as default.
Options
Add a hidden submit button with the same action first (☹️ duplication)
Put the desired submit button first in the form and then move it to the correct place via CSS (☹️ may not be feasible, may result in cumbersome styling)
Change the handling of the return key in all form inputs via JavaScript (☹️ needs javascript)
None of the options is ideal, so we choose 3. because most browsers have JavaScript enabled.
Chosen solution
// example implementation
document.addEventListener('DOMContentLoaded', (ev) => {
for (const defaultSubmitInput of document.querySelectorAll('[data-default-submit]')) {
for (const formInput of defaultSubmitInput.form.querySelectorAll('input')) {
if (formInput.dataset.ignoreDefaultSubmit != undefined) { continue; }
formInput.addEventListener('keypress', (ev) => {
if (ev.keyCode == 13) {
ev.preventDefault();
defaultSubmitInput.click();
}
})
}
}
});
<!-- example markup -->
<form action="https://postman-echo.com/get" method="get">
<input type="text" name="field1">
<input type="submit" name="submit" value="other action">
<input type="submit" name="submit" value="default action" data-default-submit> <!-- this button will be used on return -->
</form>
It may be useful to be able to remove the enhancement from some inputs. This can be achieved by:
<input type="text" name="field2" data-ignore-default-submit> <!-- uses browser standard behaviour -->
Here a complete code pen.
When a button is clicked with a mouse (and hopefully by touch), it records the X,Y coordinates. This is not the case when it is invoked by a form, and these values are normally zero.
So you can do something like this:
function(e) {
const isArtificial = e.screenX === 0 && e.screenY === 0
&& e.x === 0 && e.y === 0
&& e.clientX === 0 && e.clientY === 0;
if (isArtificial) {
return; // DO NOTHING
} else {
// OPTIONAL: Don't submit the form when clicked
// e.preventDefault();
// e.stopPropagation();
}
// ...Natural code goes here
}
Using the example you gave:
<form>
<input type="text" name="field1" /><!-- Put your cursor in this field and press Enter -->
<input type="submit" name="prev" value="Previous Page" /> <!-- This is the button that will submit -->
<input type="submit" name="next" value="Next Page" /> <!-- But this is the button that I WANT to submit -->
</form>
If you click on "Previous Page", only the value of "prev" will be submitted. If you click on "Next Page" only the value of "next" will be submitted.
If however, you press Enter somewhere on the form, neither "prev" nor "next" will be submitted.
So using pseudocode you could do the following:
If "prev" submitted then
Previous Page was click
Else If "next" submitted then
Next Page was click
Else
No button was click

I have a simple form to get a table's row/column numbers, with a button type = "submit" that reloads the page onClick .
I want to keep the warnings when the user enters an invalid value, since the inputs have a maximum/minimum number required, which is not possible with the return false; in the end of the onClick method, or event.preventDefault();
Any ideas how to do that?
This code is in JSX:
<form id="table_form">
<label>how many rows ?</label>
<input
type="number"
name="rows"
min={min_tablerows}
max={max_tablerows}
required
value={tablerows}
onChange={onChangeHandeler} />
<label>how many columns ?</label>
<input
type="number"
name="columns"
min={min_tablecolumns}
required
value={tablecolumns}
onChange={onChangeHandeler} />
<button
type="submit"
form="table_form"
onClick={onClickHandeler}>
<FontAwesomeIcon icon={faCheck} />
</button>
</form>
You want to keep the default html warnings if I understand your question well. I would like to suggest the following:
Firstly, you don't need to attach onClick event handler for the button because a button in an HTML form or with the type submit by default submits to the form it is contained.
You can attach onSubmit event handler to the main form and in its callback function prevent the default behaviour.
With this, html5 will handle any errors and prevent the form from even submitting in the first place. When it doesn't find any error, it will run the callback function attached to the form's event handler.
So your code might be as follows:
handleSubmit(e) {
e.preventDefault();
// Do what you like here
e.target.submit(); // if you want to submit the forms
}
<form id="table_form" onSubmit={this.handleSumbit.bind(this)}>
<label>how many rows ?</label>
<input
type="number"
name="rows"
min={min_tablerows}
max={max_tablerows}
required
value={tablerows}
onChange={onChangeHandeler} />
<label>how many columns ?</label>
<input
type="number"
name="columns"
min={min_tablecolumns}
required
value={tablecolumns}
onChange={onChangeHandeler} />
<button
type="submit">
<FontAwesomeIcon icon={faCheck} />
</button>
</form>
<input class="form-control" type="text" name="txtSpouseOccupation" id="txtSpouseOccupation" required>
<button type="button" id="next_personal" class="form-control btn-success" style="width:10%" onclick="openTab(event,'dependentTab')">Next</button>
when I click the next button it just goes to the next tab and ignores the required even the inputs are not yet filled up
You can accomplish your need by using this simple attribute required. So below I'll add example;
<html>
<head>
</head>
<body>
<form action="next.php">
<input type="text" required="true">
<input type="submit">
</form>
</body>
</html>
So when you click button to navigate to next page or tab it will show simple message near relevant text box to fill that field.
Though you used tabs you can use this.
In this case, your both elements are independent to each other. You have text/input whose functionality is to take inputs and then there is a submit button whose functionality to do something on click.
Now required will only work if you define a relation between submit button and input/text. <form> elements does that for you as it wraps both elements in it and than the submit button default action is to submit the form, and then before submitting it will check if the input values are assigned as per required=true.
But you trigger a function on the click of it. If you simply want to go to some url by submitting form
Try Form
<form action="your url" method="GET or POST">
<input type= "text" required ="true"/>
<button type = "submit" >next</button>
</form>
OR you can use javascript for it.
function newTab(){
let input = document.getElementById('text-input').value;
if(input === ""){
alert('please fill text')
return;
}
window.location.href = 'http://google.com';
}
<input type= "text" required ="true" id = "text-input"/>
<button type = "submit" onClick = "newTab()" >next</button>
This question already has answers here:
Multiple submit buttons in an HTML form
(27 answers)
Closed 9 years ago.
I have two submit buttons, a back submit button and a next submit button, when the user is in a text input and press enter, it takes them backwards... I think this is because enter evokes the back submit button instead of the next submit button.
<form action="" method="post">
<input type="submit" name="GOTO1" value="back" />
<input type="text" name="value1" />
<input type="submit" name="GOTO3" value="next" />
</form>
So when you are instead of the text field, and press enter it executes the first submit button, how can I change that...
Go the jQuery route...(untested).
// Prevent default on form on page load
// or on "enter"
$('form').disable();
// OR....
// Disable the ENTER key altogether on the form inputs
$('form').find('.input').keypress(function(e){
if (e.which == 13) // Enter key is keycode 13
{
return false;
}
});
$('input[type="submit"]').on('click', function() {
var btn = $(this).val();
if(btn == 'back')
{
// do this to go back, code here
}
else
{
// do this to go to next, code here
}
return false;
});
very simple workaround
<script>
function myFunction()
{
}
function myFunction2()
{
}
</script>
</head>
<body>
<form action="" method="post">
<input type="submit" name="GOTO1" value="back" onclick="myFunction2()"/>
<input type="text" name="value1" />
<input type="submit" name="GOTO3" value="next" onclick="myFunction()" />
</form>
Not neat but it works on the onclick number reference.
Hope this helps...
Use
<input type="button" ... >
You should not have more than one submit per form, since ENTER should trigger it.
To know more about it, you can take a look at this: https://stackoverflow.com/a/469084/955143
I'm using HTML5 for validating fields. I'm submitting the form using JavaScript on a button click. But the HTML5 validation doesn't work. It works only when then input type is submit. Can we do anything other than using JavaScript validation or changing the type to submit?
This is the HTML code:
<input type="text" id="example" name="example" value="" required>
<button type="button" onclick="submitform()" id="save">Save</button>
I'm submitting the form in the function submitform().
The HTML5 form validation process is limited to situations where the form is being submitted via a submit button. The Form submission algorithm explicitly says that validation is not performed when the form is submitted via the submit() method. Apparently, the idea is that if you submit a form via JavaScript, you are supposed to do validation.
However, you can request (static) form validation against the constraints defined by HTML5 attributes, using the checkValidity() method. If you would like to display the same error messages as the browser would do in HTML5 form validation, I’m afraid you would need to check all the constrained fields, since the validityMessage property is a property of fields (controls), not the form. In the case of a single constrained field, as in the case presented, this is trivial of course:
function submitform() {
var f = document.getElementsByTagName('form')[0];
if(f.checkValidity()) {
f.submit();
} else {
alert(document.getElementById('example').validationMessage);
}
}
You should use form tag enclosing your inputs. And input type submit.
This works.
<form id="testform">
<input type="text" id="example" name="example" required>
<button type="submit" onclick="submitform()" id="save">Save</button>
</form>
Since HTML5 Validation works only with submit button you have to keep it there.
You can avoid the form submission though when valid by preventing the default action by writing event handler for form.
document.getElementById('testform').onsubmit= function(e){
e.preventDefault();
}
This will give your validation when invalid and will not submit form when valid.
I may be late, but the way I did it was to create a hidden submit input, and calling it's click handler upon submit. Something like (using jquery for simplicity):
<input type="text" id="example" name="example" value="" required>
<button type="button" onclick="submitform()" id="save">Save</button>
<input id="submit_handle" type="submit" style="display: none">
<script>
function submitform() {
$('#submit_handle').click();
}
</script>
I wanted to add a new way of doing this that I just recently ran into. Even though form validation doesn't run when you submit the form using the submit() method, there's nothing stopping you from clicking a submit button programmatically. Even if it's hidden.
Having a form:
<form>
<input type="text" name="title" required />
<button style="display: none;" type="submit" id="submit-button">Not Shown</button>
<button type="button" onclick="doFancyStuff()">Submit</button>
</form>
This will trigger form validation:
function doFancyStuff() {
$("#submit-button").click();
}
Or without jQuery
function doFancyStuff() {
document.getElementById("submit-button").click();
}
In my case, I do a bunch of validation and calculations when the fake submit button is pressed, if my manual validation fails, then I know I can programmatically click the hidden submit button and display form validation.
Here's a VERY simple jsfiddle showing the concept:
https://jsfiddle.net/45vxjz87/1/
Either you can change the button type to submit
<button type="submit" onclick="submitform()" id="save">Save</button>
Or you can hide the submit button, keep another button with type="button" and have click event for that button
<form>
<button style="display: none;" type="submit" >Hidden button</button>
<button type="button" onclick="submitForm()">Submit</button>
</form>
Try with <button type="submit"> you can perform the functionality of submitform() by doing <form ....... onsubmit="submitform()">
2019 update: Reporting validation errors is now made easier than a the time of the accepted answer by the use of HTMLFormElement.reportValidity() which not only checks validity like checkValidity() but also reports validation errors to the user.
The HTMLFormElement.reportValidity() method returns true if the element's child controls satisfy their validation constraints. When false is returned, cancelable invalid events are fired for each invalid child and validation problems are reported to the user.
Updated solution snippet:
function submitform() {
var f = document.getElementsByTagName('form')[0];
if(f.reportValidity()) {
f.submit();
}
}
HTML5 Validation Work Only When button type will be submit
change --
<button type="button" onclick="submitform()" id="save">Save</button>
To --
<button type="submit" onclick="submitform()" id="save">Save</button>
Try this out:
<script type="text/javascript">
function test
{
alert("hello world"); //write your logic here like ajax
}
</script>
<form action="javascript:test();" >
firstName : <input type="text" name="firstName" id="firstName" required/><br/>
lastName : <input type="text" name="lastName" id="lastName" required/><br/>
email : <input type="email" name="email" id="email"/><br/>
<input type="submit" value="Get It!" name="submit" id="submit"/>
</form>
How do I change a form's action attribute right after clicking the submit button?
<input type='submit' value='Submit' onclick='this.form.action="somethingelse";' />
Or you can modify it from outside the form, with javascript the normal way:
document.getElementById('form_id').action = 'somethingelse';
There's a simple way to do this if you only need to support modern browsers: on your submit button, add a formaction="/alternate/submit/url" attribute like so:
<form>
[fields]
<input type="submit" value="Submit to a" formaction="/submit/a">
<input type="submit" value="submit to b" formaction="/submit/b">
</form>
It also works on <button> tags.
The gotcha is that old versions of IE (<10) and the Android Browser (<4.0) do not support it. So, if you need to support older browsers, then the existing JS answers will probably work better for you.

You can also set onSubmit attribute's value in form tag. You can set its value using Javascript.
Something like this:
<form id="whatever" name="whatever" onSubmit="return xyz();">
Here is your entire form
<input type="submit">
</form>;
<script type=text/javascript>
function xyz() {
document.getElementById('whatever').action = 'whatever you want'
}
</script>
Remember that onSubmit has higher priority than action attribute. So whenever you specify onSubmit value, that operation will be performed first and then the form will move to action.
Attach to the submit button click event and change the action attribute in the event handler.
You can do that on javascript side .
<input type="submit" value="Send It!" onClick="return ActionDeterminator();">
When clicked, the JavaScript function ActionDeterminator() determines the alternate action URL. Example code.
function ActionDeterminator() {
if(document.myform.reason[0].checked == true) {
document.myform.action = 'http://google.com';
}
if(document.myform.reason[1].checked == true) {
document.myform.action = 'http://microsoft.com';
document.myform.method = 'get';
}
if(document.myform.reason[2].checked == true) {
document.myform.action = 'http://yahoo.com';
}
return true;
}
HTML5's formaction does not work on old IE browsers. An easy fix, based on some of the responses above, is:
<button onclick="this.form.action='/PropertiesList';"
Account Details </button>
You can try this:
<form action="/home">
<input type="submit" value="cancel">
<input type="submit" value="login" formaction="/login">
<input type="submit" value="signup" formaction="/signup">
</form>
