Dynamic Add HTML event not responding

Problem description: In the page dynamic use JS added HTML set the OnClick event, the production page after the Click event is invalid and prompt:cannot read property ' xxx ' of undefined

Such as:

$ ('. Test '). Append ("<li><a href= ' javascript:void (0); ' onclick=\" Search.fn.HotSearch (' "+ V +" ') \ ">" + V + "& Lt;/a></li> ");

search.fn=function  (key) {            $ ("#_search_box"). Val (key);            Search.fn.DoSearch (true);        }, Dosearch:function(istrue) {        }} 

Problem Analysis: The main reason for this situation is that after the Dom document has been loaded,JS will not be able to listen for the element registration event because the element cannot be found, so even if the dom element is added dynamically in the future, JS is invalid. If you want to register event listening on the DOM element itself, which is dynamically added on the fly, you can take a dynamic addition to the DOM element, The element is then dynamically registered for the event listener.

In addition to the various ways to get the corresponding elements through attributes and perform event binding through the element ID, here is an alternative way:

   var html = "<li><a href= ' javascript:void (0); ' > "+ V +" </a></li> ";    var obj = $ (HTML);   Obj.bind (function  () {search.fn.HotSearch (v);});   $ ('. Test '). Append (obj);
