I guess I’ll start here, and move forward. Then, I’ll come back here and see if understand more…

Sorry for being incomprehensible. The above post is not so much an explanation of AJAX as it is an example of how I’ve put it to use in my own code.

It has support for 35 different languages, it color codes, creates hyperlinks to online language API’s, and is all-around nifty.

Plus, the person who develops it is very friendly. I reported a small bug to him and he had a new version out within hours.

The code above is just wrapped in pre tags, nothing fancy.

Thank you

To use synchronousPost, you would create an array in javascript. So, for example, you might have this javascript function in your HTML:

<script type="text/javascript">
   function helloWorld() {
      var parameterMap = new Array();
      parameterMap["name"] = "Jennifer";
	
      var result = synchronousPost("helloWorld.do", parameterMap);
      if (result) {
         var output = result.getElementsByTagName("output")[0].childNodes[0].nodeValue;
         alert(output);
      } else {
         alert("There was a problem sending the request to the server");
      }
   }
</script>

Then somewhere in your HTML, you could call this function:

<input type="button" value="Hello" onclick="helloWorld()"/>

You can see that parsing the result gets a little tricky and verbose with the DOM scripting, but you could also just return a snippet of text or HTML instead of XML, and use the javascript innerHTML property or document.write() method to add the result to your document.

Thank you.
