I dont know how to do it in plain JS.

But the jQuery equiv (look up jquery and download the library... makes ajax/javascript functionality MUCH easier)

Code: Select all

<a href="somepage.php" onclick="$('#idOfDivToLoadInto').load($(this).attr("href")); return false;">page</a>

<div id="idOfDivtoLoadInto">
    <!-- Empty div ready to be populated -->
</div>

Shouldn't be to hard to work out :)

Torn's method is a quite an easy way of doing it, but it uses DHTML, while this works, I tend to avoid it as editing the HTML each time tends to be a pain in the neck. I prefer making JavaScript events using JavaScript itself:

Raw JavaScript (important to know the workings):

http://www.w3schools.com/dom/dom_http.asp

Code: Select all

<!DOCTYPE html>
<html>
	<head>
		<title>Hello!</title>
	</head>
	<body>
		<a href="#">Click here and watch the magic happen</a>
		<div id="myDiv" style="border: #000 1px solid;">this div will contain the response :D</div>

		<script type="text/javascript">
		document.getElementsByTagName('a')[0].onmousedown = function() // the first link on the page has been clicked
		{
			var ajax = new XMLHttpRequest(); // create a new XMLHttpRequest object

			ajax.open('GET', 'myFile.html');
			ajax.send(0); // to this day I still don't know why you need to pass a parameter

			ajax.onreadystatechange = function() // goes through 5 changes, 0,1,2,3,4
			{
				if( ajax.readyState != 4 ) // waiting
				{
					document.getElementById('myDiv').innerHTML = 'Loading...'; // fill in our div with 'Loading...'
				}
				if( ajax.readyState == 4 ) // good to go, request is complete, we should have our content
				{
					document.getElementById('myDiv').innerHTML = ajax.responseText; // fill our div with the response
				}
			}
		}
		</script>

	</body>
</html>
using jQuery (download from http://jquery.com/):

http://api.jquery.com/jQuery.get/

Code: Select all

<!DOCTYPE html>
<html>
	<head>
		<title>Hello!</title>
		<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.min.js"> // inculde jquery </script>
		<script type="text/javascript">
		$(document).ready( function()
		{
			// add a click event to our link
			$('a[href="#"]').click( function()
			{
				$.get('myFile.html', function(data)
				{
					$('#myDiv').html(data); // fill our div with the data
				});
			})
		});
		</script>
	</head>
	<body>
		<a href="#">Click here and watch the magic happen</a>
		<div id="myDiv" style="border: #000 1px solid;">this div will contain the response :D</div>
	</body>
</html>

Im not sure what your problem is.

Still can't follow this completely. When you say "it won't," What is is doing?

Is the only way to do this by using the '#' symbol? I can't get it to work with anything else other than that, even when I do change the $('a[href="#"]').click( function() to whatever symbol.

No, that was more for the example, I like to add these things so people ask questions. So well done to you.

Basically jQuery makes use of CSS like selectors. http://www.w3.org/TR/selectors/#selectors

You might notice in the HTML I have an anchor with the href attribute set to #.

Code: Select all

<a href="#">Click here and watch the magic happen</a>
Basically $('a[href="#"]') will search for all a tags with the attribute href set to #, I could search for anything I want though.

Code: Select all

$('a[href="lol.php"]').click( function() { alert('haha') } );

Code: Select all

<a href="lol.php">lol</a>

Code: Select all

$('a[id="myLink"]').click( function() { alert('haha') } );

Code: Select all

<a href="lol.php" id="myLink">lol</a>
or simply:

Code: Select all

$('#myLink').click( function() { alert('haha') } );
You can also just simply search all anchor elements:

Code: Select all

$('a').click( function(){ alert($(this).attr('href')) });

Code: Select all

<a href="haha">lol</a><br />
<a href="pff">:D</a>

This can of course also be used for different types of elements:

Code: Select all

$('input').click( function() { alert('you clicked the button') } );

Code: Select all

<input type="button" value="click me" />

Sadly my knowledge of Ajax/JQ/JS is minimal at best, and I was unable to get any of that to work.

However, I did finally get your script to work the way I wanted it to.

The Market in my game has 4 different sections to it. One for weapons, armor etc. So, when a certain link was clicked (To whatever part of the market) I needed it to load that part of the market. I couldn't get it to work with anything other than the #

So, here's what I did, it may look like ugly coding, but it does get the job done, unless there's a more efficient way to do it.

Code: Select all

<!DOCTYPE html>
<html>
   <head>
      <title>Hello!</title>
      <script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.min.js"> // inculde jquery </script>
      <script type="text/javascript">
      $(document).ready( function()
      {
         // add a click event to our link
         $('a[href="#1"]').click( function()
         {
            $.get('myFile.html', function(data)
            {
               $('#myDiv').html(data); // fill our div with the data
            });
         })
      });
      </script>
      
            <script type="text/javascript">
      $(document).ready( function()
      {
         // add a click event to our link
         $('a[href="#2"]').click( function()
         {
            $.get('myFile2.html', function(data)
            {
               $('#myDiv').html(data); // fill our div with the data
            });
         })
      });
      </script>
   </head>
   <body>
      <a href="#1">Click here and watch the magic happen</a>
      <a href="#2">Click here and watch the magic happen</a>
      <div id="myDiv" style="border: #000 1px solid;">this div will contain the response :D</div>
   </body>

         {
            e.preventDefault();
            var href = $(this).attr('href')

            $.get(href, function(data)
            {
               $('#myDiv').html(data); // fill our div with the data

   </head>
   <body>
      <a href="myFile.html">Click here and watch the magic happen</a>
      <a href="myFiel2.html">Click here and watch the magic happen</a>

PERFECT! Thank you!

I really need to find the time to learn JS. I've seen alot of cool things done with it.
