  • Delegated Bindings in JQUERY

    Importance of delegated bindings mainly arises when using dynamically created elements.

    We can do the binding by using “on ()” this way we can process events from elements that are included pro-grammatically to the document.

    This allows us to attach a single event listener for elements that exist now or in the future. Direct binding does not fire newly created elements events. See the difference between

    $(document).on (‘click’, ‘elementid’, function () {…

    and

    $(‘#elementid’).on (‘click’, function () {….

    Explanation:

    By delegating an event handler, it will fire the events of elements that did not exist in the DOM at the time of binding.If you call the event with its Id then the element specified should be defined in the DOM at the time of execution.

    The better way is to attach events in the way that it can be executed as appropriate later on.
