Invoke Java servlet with YUI

Difficulty:
In one of my previous post I showed you how to invoke a Java servlet with Ajax/Javascript.
Now I will show you the same example with the use of Yahoo UI Library (YUI Library).

Make sure you implement the yahoo and connection libraries.
You can download these from the YUI developer network.

<script type="text/javascript" src="static/js/yui/yahoo-min.js"></script>
<script type="text/javascript" src="static/js/yui/connection-min.js"></script>

The script:

<script type="text/javascript">
      var request;
      function doSomeRequest(servletName, servletArguments){
          var arg = "myParam=" + getPopupContent(servletArguments).replace(/[\n\r\%]/g,''); //I replaced linebreaks and % which breaks requests.
          YAHOO.util.Connect.asyncRequest('POST', servletName, callback, arg); //note the arg is only for POST methods
          	var callback =
			{
			  success: function(o) {
			  	//do something with the response
			  },
			  failure: function(o) {
			  	//do something with the error
			  }
			}
		}
</script>
