jquery dynamic add element failed to trigger binding event

After adding elements dynamically with jquery, it is not possible to trigger events for dynamically added elements. The solution is as follows:

Method One: Bind the Live event (the live event is only supported under jquery1.9, not supported in the high version).

123	$(".newBtn").live("click",function(){ ///jquery 1.9(不包括1.9)以下可以               alert(‘这里是动态元素添加的事件‘);           })

method Two: Take advantage of the on () event binding ($ (Parentele). On ("click", ". Thisele", function () {})

123

$ ("Body"). On ("click", ". Newbtn", function () {                 alert ( ' Here is an event added by dynamic Element '); &NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP; br >// The Parentele here is Thisele's father or ancestor element, Parentele can be document, body, etc. < br >< BR >< BR >//Note: If the function called at this time is an externally defined function, do not add () at the time of the call, or skip the click event directly triggering the function

  $ ("Body"). On ("click", ". Newbtn", AA);

function aa () {
        Alert (' Here is the event of dynamic element addition ');
  }
