jquery on submit button click code example

Example 1: jquery submit form

// It is simply
$('form').submit();

// However, you're most likely wanting to operate on the form data
// So you will have to do something like the following...
$('form').submit(function(e){
	// Stop the form submitting
  	e.preventDefault();
  	// Do whatever it is you wish to do
  	//...
  	// Now submit it 
    // Don't use $(this).submit() FFS!
  	// You'll never leave this function & smash the call stack! :D
  	e.currentTarget.submit();
});

Example 2: jquery enable submit button

//jQuery 1.6+ use:
$("#submitButtonID").prop('disabled', true); //disable 
$("#submitButtonID").prop('disabled', false); //enable

//jQuery 1.5 and below use:
$("#submitButtonID").attr('disabled','disabled'); //disable 
$("#submitButtonID").removeAttr('disabled'); //enable

Example 3: ajax post form listener button

$("button").click(function(e) {
    e.preventDefault();
    $.ajax({
        type: "POST",
        url: "/pages/test/",
        data: { 
            id: $(this).val(), // < note use of 'this' here
            access_token: $("#access_token").val() 
        },
        success: function(result) {
            alert('ok');
        },
        error: function(result) {
            alert('error');
        }
    });
});
