Get value using jquery from button clicked - html

I'm building a form consisted of button. I want to get value from a highlighted button being sent to a parameter when submit button is clicked, but the problem is I only found a way to sent value from a radio button. Is there any equivalent way to do this?
I know this is only applicable for radio button, so I'm searching an equivalent queryselector that will give exact action like code below but for button
document.querySelector('input[name=customButton]:checked').value
<button type="button" class="btn" id="customButton1" name="customButton" value="1">
<label for="customButton1">Excellent</label>
<button type="button" class="btn" id="customButton2" name="customButton" value="2">
<label for="customButton2">Not good</label>

You cannot convert a radio directly to a button like you did. The HTML is not valid
You can style a radio like a button or do this
document.getElementById("myForm").addEventListener("click",function(e) {
const tgt = e.target.closest("button")
if (tgt.matches(".customButton")) document.getElementById("customButton").value = tgt.value
})
<form id="myForm">
<input type="hidden" name="customButton" id="customButton" value="" />
<button type="button" class="btn customButton" value="1">Excellent</button>
<button type="button" class="btn customButton" value="2">Not good</button>
</form>

Appending values to a URL

So I am building an ecommerce website and I am at the product page. I want a filter system where the filter values get appended to the existing URL instead of loading a new URL of the latest filter parameter.
For example, if I have two elements as such:
<input type="checkbox" name="checkbox1" value="test1">
and
<input type="button" name="button1" value="a button">
and each are from different forms.
Let's say I submit the first form. The url becomes:
.../?checkbox1=test1
When I also submit the second form (after submitting the first form), the url now becomes:
.../?button1=a button
But I want the value of the button to be appended to the first url like:
.../?checkbox1=test1&button1=a button
How do I go about this?
Thanks
Have ONE form or do this
document.querySelector("[name=button1]").addEventListener("click",function(e) {
const chk = document.querySelector("[name=checkbox1]")
const but = this.value
let url = "/?button1=a%20button";
if (chk.checked) url +=`&${chk.name}=${chk.value}`;
//location = url
console.log(url)
})
<input type="checkbox" name="checkbox1" value="test1">
<input type="button" name="button1" value="a button">
Why you don't go like this ? Only single form :
<html>
<body>
<form action="redirect.html">
<input type="checkbox" name="checkbox1" value="test1"> <br><br>
<input type="button" name="button1" value="a button"> <br><br>
<input type="submit" name="submit-btn" value="submit">
</form>
</body>
</html>

Page reloads when input type="number" is changed by buttons

To simplify I have a basic HTML structure where inside an I have one number input and it's respective add and subtracts buttons. Every time one of the buttons it's clicked the page automatically reloads. How do I prevent that from happening?
This is my code:
<form>
...
<button onclick="this.parentNode.querySelector('input[type=number]').stepDown()" class="icon-number ver"></button>
<input class="quantity" min="0" max="99" name="quantity" value="1" type="number">
<button onclick="this.parentNode.querySelector('input[type=number]').stepUp()" class="plus icon-number ver"></button>
<button class="btn-form btn-add-cart" type="submit">ADD TO CART</button>
</form>
The issue disappears when I remove the form tag, but I would like to keep it.
I am not using any javascript on this code, it's just HTML.
It may be submitting the form after you click the button.
I tried your code at my local machine and could fix it using attribute type like this.
<button type="button" onclick="this.parentNode.querySelector('input[type=number]').stepUp()" class="plus icon-number ver"></button>
Make sure your functions are returning false
<form>
...
<button onclick="this.parentNode.querySelector('input[type=number]').stepDown(); return false;" class="icon-number ver"></button>
<input class="quantity" min="0" max="99" name="quantity" value="1" type="number">
<button onclick="this.parentNode.querySelector('input[type=number]').stepUp(); return false;" class="plus icon-number ver"></button>
<button class="btn-form btn-add-cart" type="submit">ADD TO CART</button>
</form>

User should not be able to select the button which is already selected

Button group is not working as it should, the problem is if the "ON" is selected, it should not be selected again, but the problem is even the "ON" button is selected I am able to select the ON button again.
How can I stop my button to stop any action when the button is already selected.
This is my code for my button group:
<form action="myclass.php" method="post">
<div class="btn-group" data-toggle="buttons">
<label class="btn btn-default btn-xs myOnbutton">
// myOnbutton is the button name
<input type="radio" autocomplete="off"> ON
</label>
<label class="btn btn-default btn-xs myOffbutton">
// myOffbutton is the button name
<input type="radio" autocomplete="off"> OFF
</label>
</div>
</form>
Do anyone knows where I am making the mistake, so it is selecting the button again.
This is basic HTML. It has nothing to do with bootstrap, you just need to add names to the checkboxes so you cant select both.
<label class="btn btn-default btn-xs myOnbutton">
<input type="radio" autocomplete="off" name="switch"> ON
</label>
<label class="btn btn-default btn-xs myOffbutton">
<input type="radio" autocomplete="off" name="switch"> OFF
</label>
if you want to disable the groups after first selection,you should use jquery like Plunker :
$(".btn-xs :radio").click(function(){
$(".btn-xs :radio").attr("disabled", true); //Disable all with the same name
});
and if you want to disable selected radio button only,Plunker :
$(".btn-xs :radio").click(function(){
$(this).attr("disabled", true); //Disable all with the same name
});

Colorized submit button after html form validation with parsley.js

I am using Parsley.js for validating my Bootstrap formatted HTML forms. It works pretty fine. What I want to do now is to change the color for the submit button if validation fails.
I read the documentation from Parsley.js, but I could not find something like adding a class to the submit button, depending on validation.
Example:
<form>
<input type="text" id="fehler" name="fehler" required>
<button type="submit" class="btn btn-default">Submit</button>
</form>
After click (and validation) should it change to something like this:
<button type="submit" class="btn btn-default novalid"></button>
or this:
<button type="submit" class="btn btn-danger"></button>
Try this :
Put an ID on your button like "validateFormButton" and create this method to call after sending your form :
function change_class(formIsValid) {
var btn = document.getElementById("validateFormButton");
if(formIsValid)
btn.className= "btn btn-default novalid";
else
btn.className= "btn btn-danger";
}

Two submit buttons in one form

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");
});
