Question

I want Enable/Disable click event on element. I have following code...

HTML:

jQuery:

    });
    $this.html("Processing...").css({

        "cursor": "default"
    });
    $.ajax({
        type: 'post',
        url: 'abc.jsp',
        success: function(process) {
            //My code goes here...
            $this.on("click"); //  Here i want to bind or add handler which is fired previously.
        }
    });
});

Answer 1

If I understand well, you could do that very simple with the following:

$this.html("Processing...").css({
    "cursor": "wait",
    "pointer-events": "none"
});

Answer 2

Add some class when performing AJAX request. Remove when done. Do nothing if link has this class.

$(document).on("click", "#CP", function(event) {
    event.preventDefault();
    $a = $(this);
    if($a.hasClass('disabled')) {
        return false;
    }

    $a.html("Processing...").addClass('disabled');
    $.ajax({
        type: 'post',
        url: 'abc.jsp',
        success: function(process) {
            $a.removeClass('disabled');

            // restore inner HTML here
        }
    });
});
