I have a form that has two buttons. One for saving a record and the other for cancelling the save procedure. I am using the rails.js (a common AJAX/jQuery plug-in for those of you not in the know) javascript file that works with jQuery for unobtrusive javascript/ajax calls. When I send the form data over ajax, I want the name and value of the button I clicked to be submitted with the rest of the data so that I can make a decision on what to do based on which button was clicked.
The method in the rails.js file uses .serializeArray() for sending form data to the server. The problem is that this doesn't include the name/value pair of the button I've clicked. jQuery's website states that they do this on purpose (eventhough its my opinion that they should):
"The .serializeArray() method uses the standard W3C rules for successful controls to determine which elements it should include; in particular the element cannot be disabled and must contain a name attribute. No submit button value is serialized since the form was not submitted using a button."
How can they assume that a form WASN'T submitted using a button? This makes no sense and a wrong assumption I believe.
Under the W3C rules the button which was activated for the submission of a form is considered a successful control.
Since the developers of jQuery have decided to do this on purpose, can I assume that there is another method that DOESN'T exclude the activated button in a serialization?
EDIT: Here is quick example of what my form might look like...
<!DOCTYPE html5>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#form').submit(function(e) {
// put your breakpoint here to look at e
var x = 0;
});
});
</script>
</head>
<body>
<form id="form">
<input name="name" type="text"><br/>
<input name="commit" type="submit" value="Save"/>
<input name="commit" type="submit" value="Cancel"/>
</form>
</body>
