<form onsubmit="return confirm('Are you sure you want to rollback deletion of candidate table?')">
<input type='submit' name='delete' value='Undo' />
<input type='submit' name='no' value='No' />
when the user clicks on second submit button i.e No i want to display the confirmation dialogue as "Are you sure you want to commit the transaction."
<form method='post'>
<input type='submit' name='undo' value='Undo' onclick="return confirm('Are you sure you want to rollback deletion of candidate table?')"/>
<input type='submit' name='no' value='No' onclick="return confirm('Are you sure you want to commit delete and go back?')"/>
</form>
Worked fine.
just changed onsubmit() to onclick(). as the function of both in this situation is same.
You could bind to onclick instead of onsubmit - see below.
<script>
function submitForm() {
return confirm('Rollback deletion of candidate table?');
}
<script>
<form>
<input type='submit' onclick='submitForm()' name='delete' value='Undo' />
<input type='submit' onclick='submitForm()' name='no' value='No' />
</form>
Or alternately, using jQuery:
<script>
$(document).ready(function() {
$('form input[type=submit]').click(function() {
return confirm('Rollback deletion of candidate table?');
});
});
<script>
<form onsubmit="submitFunction();">
<input type='submit' name='delete' value='Undo' />
<input type='button' onclick="declineFunction()" name='no' value='No' />
</form>
I wouldnt try to create a submit but rather just a button that has a onclick="function()" and then use javascript to set a variable to see how many times they have clicked it and a alert();
hope this helps :D
Here's an event-listener based solution that avoids inline event handlers (useful if your site has a Content Security Policy that forbids inline JavaScript):
HTML:
<form method="post">
<input type="submit" id="deleteButton" name="delete" value="Undo" />
<input type="submit" id="noButton" name="no" value="No" />
</form>
JS:
document.getElementById("deleteButton").addEventListener("click", function(evt) {
if (!confirm("Are you sure you want to rollback deletion of candidate table?")) {
evt.preventDefault();
}
});
document.getElementById("noButton").addEventListener("click", function(evt) {
if (!confirm("Are you sure you want to commit the transaction?")) {
evt.preventDefault();
}
});
Just use two of the same form. One for each button:
<form onsubmit="return confirm('Are you sure you want to rollback deletion of candidate table?')">
<input type='submit' name='delete' value='Undo' />
</from>
<form onsubmit="return confirm('Are you sure you want to rollback deletion of candidate table?')">
<input type='submit' name='no' value='No' />
</from>
Also, if you would done your research you would find these:
Javascript onsubmit with form with multiple submits buttons
HTML form with two submit buttons and two "target" attributes
Form onSubmit determine which submit button was pressed
How can I get the button that caused the submit from the form submit event?
Two submit buttons in one form
how can I replace this code, by only one Form please.
<form method="post" action="<c:url value="/deconnexion" />"><input type="submit" value="Déconnexion" class="deco" /></form>
<form method="post" action="<c:url value="/accueil" />"><input type="submit" value="Retour" class="deco" /></form>
What you want to do is impossible, each form will submit it's information to a single location, which is your action property in your form.
What you can do, alternatively, is manage two different cases in the same form. Your form would look like that :
<form method="post" action="<c:url value="/redirection" />">
<input id="deco" type="submit" value="Déconnexion" class="deco" />
<input id="retour" type="submit" value="Retour" class="deco" />
<input id="type" name="type" type="hidden" value="" />
</form>
You would need Javascript (Jquery) code to assign the type of redirection in the hidden field before the form is submitted :
<script type="text/javascript">
$('#deco').click(function(event)
{
$('#type').val("Déconnexion");
});
$('#retour').click(function(event)
{
$('#type').val("Retour");
});
</script>
Then, in the PHP, you would redirect to the page or function you wish with this condition :
if ($_POST["type"] == "Déconnexion")
// Do something
else if ($_POST["type"] == "Retour"
// Do something else
I have a form which has an iframe as target. It works well when using the classic "submit" button, but when I use Jquery to submit the form, it opens a new window and does not target in the iframe. Any suggestion on why this happens?
Here is my code:
function formSubmit() {
$('#formId').submit();
}
<form name="formId" id="formId" action="ajax/submitForm.php" method="post" target="iframe_submit" tmt:validate="true">
[...]
<input type="button" id="submit_button" value="GO" onclick="javascript:formSubmit();" />
</form>
<iframe style="border:none;width:0px;height:0px" id="iframe_submit" name="iframe_submit"></iframe>
try with
$('#formId').get(0).submit();
Problem not in iframe but in onclick="javascript:formSubmit();". For start you don't need to write javascript: in on..="" attributes. But better to use jQuery events:
<form name="formId" id="formId" action="ajax/submitForm.php" method="post" target="iframe_submit">
<input type="text" name="x" />
<input type="button" id="submit_button" value="GO" />
</form>
and:
function ftformSubmit() {
$('#formId').submit();
}
$(function(){
$('#submit_button').click(function(){
$('#formId').submit();
});
});
See fiddle
I have a search form
<form id="search" method="GET">
<input type="text" name="q" id="q" />
<input type="submit" value="search" name="submit" id="submit" />
</form>
and when I submit it it adds ?q=&submit=submit to the URL is there a way that I can keep it from appending submit=submit but still pass the q=?
If you remove the name attribute from your <input type="submit" /> then that should get rid of submit=submit from the querystring (a quick test in Firefox / Firebug confirmed this). For example:
<input type="submit" value="search" />
Try using a button:
<button type="submit">Submit Form</button>
Would using post instead of get be out of the question because that wouldn't show anything in the url.
Change the button's name to name=''
Change the button type from:
type="submit"
To:
type="button"
i.e.
<button type="button">Login</button>
You could just use an anchor instead of a form input:
<script type="text/javascript">
function submitForm() {
document.getElementById('search').submit();
}
</script>
<form id="search" method="GET">
<input type="text" name="q" id="q" />
Submit
</form>
Or, you could add an onsubmit to the form, and use javascript to disable the input field, which should keep it from showing in the URL.
No. You would need to remove the input.
I have two submit buttons in a form. How do I determine which one was hit serverside?
Solution 1:
Give each input a different value and keep the same name:
<input type="submit" name="action" value="Update" />
<input type="submit" name="action" value="Delete" />
Then in the code check to see which was triggered:
if ($_POST['action'] == 'Update') {
//action for update here
} else if ($_POST['action'] == 'Delete') {
//action for delete
} else {
//invalid action!
}
The problem with that is you tie your logic to the user-visible text within the input.
Solution 2:
Give each one a unique name and check the $_POST for the existence of that input:
<input type="submit" name="update_button" value="Update" />
<input type="submit" name="delete_button" value="Delete" />
And in the code:
if (isset($_POST['update_button'])) {
//update action
} else if (isset($_POST['delete_button'])) {
//delete action
} else {
//no button pressed
}
If you give each one a name, the clicked one will be sent through as any other input.
<input type="submit" name="button_1" value="Click me">
There’s a new HTML5 approach to this, the formaction attribute:
<button type="submit" formaction="/action_one">First action</button>
<button type="submit" formaction="/action_two">Second action</button>
Apparently this does not work in Internet Explorer 9 and earlier, but for other browsers you should be fine (see: w3schools.com HTML <button> formaction Attribute).
Personally, I generally use JavaScript to submit forms remotely (for faster perceived feedback) with this approach as backup. Between the two, the only people not covered are Internet Explorer before version 9 with JavaScript disabled.
Of course, this may be inappropriate if you’re basically taking the same action server-side regardless of which button was pushed, but often if there are two user-side actions available then they will map to two server-side actions as well.
As noted by Pascal_dher in the comments, this attribute is also available on the <input> tag as well.
An even better solution consists of using button tags to submit the form:
<form>
...
<button type="submit" name="action" value="update">Update</button>
<button type="submit" name="action" value="delete">Delete</button>
</form>
The HTML inside the button (e.g. ..>Update<.. is what is seen by the user; because there is HTML provided, the value is not user-visible; it is only sent to server. This way there is no inconvenience with internationalization and multiple display languages (in the former solution, the label of the button is also the value sent to the server).
This is extremely easy to test:
<form action="" method="get">
<input type="submit" name="sb" value="One">
<input type="submit" name="sb" value="Two">
<input type="submit" name="sb" value="Three">
</form>
Just put that in an HTML page, click the buttons, and look at the URL.
Use the formaction HTML attribute (5th line):
<form action="/action_page.php" method="get">
First name: <input type="text" name="fname"><br>
Last name: <input type="text" name="lname"><br>
<button type="submit">Submit</button><br>
<button type="submit" formaction="/action_page2.php">Submit to another page</button>
</form>
<form>
<input type="submit" value="Submit to a" formaction="/submit/a">
<input type="submit" value="submit to b" formaction="/submit/b">
</form>
The best way to deal with multiple submit buttons is using a switch case in the server script
<form action="demo_form.php" method="get">
Choose your favorite subject:
<button name="subject" type="submit" value="html">HTML</button>
<button name="subject" type="submit" value="css">CSS</button>
<button name="subject" type="submit" value="javascript">JavaScript</button>
<button name="subject" type="submit" value="jquery">jQuery</button>
</form>
Server code/server script - where you are submitting the form:
File demo_form.php
<?php
switch($_REQUEST['subject']) {
case 'html': // Action for HTML here
break;
case 'css': // Action for CSS here
break;
case 'javascript': // Action for JavaScript here
break;
case 'jquery': // Action for jQuery here
break;
}
?>

Maybe the suggested solutions here worked in 2009, but I’ve tested all of this upvoted answers and nobody is working in any browsers.
The only solution I found working was this (but it's a bit ugly to use I think):
<form method="post" name="form">
<input type="submit" value="dosomething" onclick="javascript: form.action='actionurl1';"/>
<input type="submit" value="dosomethingelse" onclick="javascript: form.action='actionurl2';"/>
</form>
You formaction for multiple submit buttons in one form
example:
<input type="submit" name="" class="btn action_bg btn-sm loadGif" value="Add Address" title="" formaction="/addAddress">
<input type="submit" name="" class="btn action_bg btn-sm loadGif" value="update Address" title="" formaction="/updateAddress">
An HTML example to send a different form action on different button clicks:
<form action="/login" method="POST">
<input type="text" name="username" value="your_username" />
<input type="password" name="password" value="your_password" />
<button type="submit">Login</button>
<button type="submit" formaction="/users" formmethod="POST">Add User</button>
</form>
The same form is being used to add a new user and login user.
Define name as array.
<form action='' method=POST>
(...) some input fields (...)
<input type=submit name=submit[save] value=Save>
<input type=submit name=submit[delete] value=Delete>
</form>
Example server code (PHP):
if (isset($_POST["submit"])) {
$sub = $_POST["submit"];
if (isset($sub["save"])) {
// Save something;
} elseif (isset($sub["delete"])) {
// Delete something
}
}
elseif very important, because both will be parsed if not.
Since you didn't specify what server-side scripting method you're using, I'll give you an example that works for Python, using CherryPy (although it may be useful for other contexts, too):
<button type="submit" name="register">Create a new account</button>
<button type="submit" name="login">Log into your account</button>
Rather than using the value to determine which button was pressed, you can use the name (with the <button> tag instead of <input>). That way, if your buttons happen to have the same text, it won't cause problems. The names of all form items, including buttons, are sent as part of the URL.
In CherryPy, each of those is an argument for a method that does the server-side code. So, if your method just has **kwargs for its parameter list (instead of tediously typing out every single name of each form item) then you can check to see which button was pressed like this:
if "register" in kwargs:
pass # Do the register code
elif "login" in kwargs:
pass # Do the login code
<form method="post">
<input type="hidden" name="id" value="'.$id.'" readonly="readonly"/>'; // Any value to post PHP
<input type='submit' name='update' value='update' formAction='updateCars.php'/>
<input type='submit' name='delete' value='delete' formAction='sqlDelete.php'/>
</form>
I think you should be able to read the name/value in your GET array. I think that the button that wasn't clicked won't appear in that list.
You can also do it like this (I think it's very convenient if you have N inputs).
<input type="submit" name="row[456]" value="something">
<input type="submit" name="row[123]" value="something">
<input type="submit" name="row[789]" value="something">
A common use case would be using different ids from a database for each button, so you could later know in the server which row was clicked.
In the server side (PHP in this example) you can read "row" as an array to get the id.
$_POST['row'] will be an array with just one element, in the form [ id => value ] (for example: [ '123' => 'something' ]).
So, in order to get the clicked id, you do:
$index = key($_POST['row']);
key
As a note, if you have multiple submit buttons and you hit return (ENTER key), on the keyboard the default button value would be of the first button on the DOM.
Example:
<form>
<input type="text" name="foo" value="bar">
<button type="submit" name="operation" value="val-1">Operation #1</button>
<button type="submit" name="operation" value="val-2">Operation #2</button>
</form>
If you hit ENTER on this form, the following parameters will be sent:
foo=bar&operation=val-1
The updated answer is to use the button with formaction and formtarget
In this example, the first button launches a different url /preview in a new tab. The other three use the action specified in the form tag.
<button type='submit' class='large' id='btnpreview' name='btnsubmit' value='Preview' formaction='/preview' formtarget='blank' >Preview</button>
<button type='submit' class='large' id='btnsave' name='btnsubmit' value='Save' >Save</button>
<button type='submit' class='large' id='btnreset' name='btnsubmit' value='Reset' >Reset</button>
<button type='submit' class='large' id='btncancel' name='btnsubmit' value='Cancel' >Cancel</button>
Full documentation is here
In HTML5, you can use formaction & formmethod attributes in the input field
<form action="/addimage" method="POST">
<button>Add image</button>
<button formaction="/home" formmethod="get">Cancel</button>
<button formaction="/logout" formmethod="post">Logout</button>
</form>
You can also use a href attribute and send a get with the value appended for each button. But the form wouldn't be required then
href="/SubmitForm?action=delete"
href="/SubmitForm?action=save"
You can present the buttons like this:
<input type="submit" name="typeBtn" value="BUY">
<input type="submit" name="typeBtn" value="SELL">
And then in the code you can get the value using:
if request.method == 'POST':
#valUnits = request.POST.get('unitsInput','')
#valPrice = request.POST.get('priceInput','')
valType = request.POST.get('typeBtn','')
(valUnits and valPrice are some other values I extract from the form that I left in for illustration)
Since you didn't specify what server-side scripting method you're using, I'll give you an example that works for PHP
<?php
if(isset($_POST["loginForm"]))
{
print_r ($_POST); // FOR Showing POST DATA
}
elseif(isset($_POST["registrationForm"]))
{
print_r ($_POST);
}
elseif(isset($_POST["saveForm"]))
{
print_r ($_POST);
}
else{
}
?>

Forms
When click on Login -> loginForm
When click on Save -> saveForm
When click on Register -> registrationForm
Simple. You can change the action of form on different submit buttons click.
Try this in document.Ready:
$(".acceptOffer").click(function () {
$("form").attr("action", "/Managers/SubdomainTransactions");
});
$(".declineOffer").click(function () {
$("form").attr("action", "/Sales/SubdomainTransactions");
});
