jquery - Click event is not working for button -


i having problems button btndel not working when click.

here's script:

$('#btnadd').bind('click', function() {     var scount = $("#support-list").find('li').length;     var tmpstr = $('#txtaddsupportname').val();     var str = “<li>";     var str += “<img src='../wp-content/plugins/hamajob/admin/assets/image/arrow.png'  width='16' height='16' class='handle'/>";      str += "<strong alt="+ scount +">" + tmpstr + "</strong>";     str += "<input type='button' id='btndel'/>";     str += "</li>";      $('#support-list').append(str); });  $('#btndel').bind('click', function(){       alert(this); });

however, script work:

str += "<input type='button' id='btndel' onclick='btndel(this)'/>"; btndel = function(e){ alert(this); }

could explain difference?

the newly added delete button not in dom, thats reason why first example not working. use .delegate()

check updated code jsfiddle

$('#btnadd').bind('click', function() {     var scount = $("#support-list").find('li').length;     var tmpstr = $('#txtaddsupportname').val();     var str = "<li>";      str += "<img src='../wp-content/plugins/hamajob/admin/assets/image/arrow.png'  width='16' height='16' class='handle'/>";      str += "<strong alt="+ scount +">" + tmpstr + "</strong>";     str += "<input type='button' id='btndel'/>";     str += "</li>";     $('#support-list').append(str); }); $( "#support-list" ).delegate( "#btndel", "click", function(){         alert(this); });
