Monitoring DOM Changes in JQuery

Question

Is there a way to detect when the disabled attribute of an input changes in JQuery. I want to toggle the style based on the value.

I can copy/paste the same enable/

Although there are more efficient ways of tackling this problem, one way of handling this is by running a function every xx seconds that will set the required CSS classes on disabled elements:

window.setInterval(1000,function() {
    $("input:disabled").addClass("disabled");
    $("input:enabled").removeClass("disabled");
});

This will check all input elements every second. But again, this is a VERY bad solution. You would be better off restructuring your code.

Without changing too much of your code and HTML, I would do something like this (didn't test it though):

$("input[name^=Group]").change(function () {
        var disabled = ($(this).val() == "No") ? "disabled" : "";
        var groupName = $(this).attr("name");

        $("#" + groupName + "Fields input")
             .attr("disabled", disabled)
             .addClass("disabled");

        //remove disabled style to all enabled controls
        $("input:enabled)").removeClass("disabled");
    });
