Mastering jQuery: Delegating a Toggle操作

Is there a way to implement a toggle function for an element that is generated dynamically? I am having trouble with my current code:

Javascript

          $("body").on('click', ".buttonA", function(){
              function() {
                  // perform some tasks
              },
              function() {
                  // undo the tasks
              }
      });

Answer №1

Give this a shot:

$('body').on('click','.buttonA', function () {
var toggled = $(this).data('toggled');
$(this).data('toggled', !toggled);
if (!toggled) {
    //..perform actions
}
else {
   //..undo actions
}});

Answer №2

Incorporating jQuery in your code allows you to utilize the .live() function for connecting a dynamically generated element.

$('#hello').live("click", function() {
  alert( "Goodbye!" ); // jQuery 1.3+
});

It has been quite some time since I last utilized jQuery, so I am uncertain about the validity of this method. However, creating a new function to address this requirement is straightforward. The crucial aspect is ensuring that the element is bound appropriately.
