Hi experts,

I have a first html page (called "index.htm") containing 3 <div>, 1 for the header, 1 for the left menu and the 3rd one for the content. They are identified with id "haut", "gauche" and "principal". In the "haut" area I have a link "Accueil". I have also 2 links in "gauche" area "Nos modèles" and "Calcul des prix".

A second html page (called "principale.htm) contains informations with 3 anchors called "voitureVedette", "lesModeles" and "calculDuPrix".

I've tried to create a javascript function called "chargerContenu" with argument "contenuDemande" where I give the content I want to be displayed into <div id="principal">. For example, I use "onLoad" event with the <body> to load the page "principal.htm#voitureVedette" but it doesn't work.

I also want my 3 links to load into <div id="principal"> page principal.htm where:
"Accueil" loads "principal.htm#voitureVedette"
"Nos modèles" loads "principal.htm#lesModeles"
"Calcul des prix" loads "principal.htm#calculDuPrix"

NOTES TO EXPERTS:

1) I want to use javascript to achieve my code. I'm learning and want to understand what happens.

2) My javascript is not part of my document, it is refered into a link in my <head> and modified it here to give you the complete code (my head contains: "<SCRIPT LANGUAGE="Javascript" SRC="scripts/messcripts.js"> </SCRIPT>" where my function is).

Thanks,
<html>
<head>
<SCRIPT language="Javascript">
<!--
    function chargerContenu(contenuDemande){
        document.getElementById("principal").style.display = contenuDemande;
    }
// -->
</SCRIPT>
</head>
 
<body onload="chargerContenu("principale.htm#voitureVedette")>
    <div id="haut" style="position: absolute; top: 9px; left: 15px; width: 388px; height: 49px;">
		<h1>Gaug-Auto</h1>
		<a href="javascript:;" onclick="chargerContenu("principale.htm#calculDuPrix")" alt="Retour à l'accueil">Accueil</a></div>
	
    <div id="gauche" style="position: absolute; top: 120px; left: 0px; width: 170px;">
		<ul>
			<li><font face="Arial" size="4"><a href="javascript:;" onclick="chargerContenu("principale.htm#lesModeles")">Nos modèles</a></font></li>
			<li><font face="Arial" size="4"><a href="javascript:;" onclick="chargerContenu("principale.htm#calculDuPrix")">Calcul des prix</a></font></li>
		</ul>
	</div>
	
	<div id="principal" style="position: absolute; top: 80px; left: 200px;" align="center">
		<!-- allo -->
	</div>
	
 
</body>
</html>

To load one html file into another you have two options. Use an iframe and set the iframe's src attribute, or do an ajax call and append the response to the existing document.

I suggest using the jQuery (http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js) library since it will save you from dealing with all the muck of ajax calls with various browsers.

Using jQuery you could load a document using the following method
<script type="text/javascript" src="jquery-1.3.2.min.js"></script>
<script type="text/javascript">

$(function() {

function loadContentWithAnchor(id, url, anchor)
{
      $("#" + id).load(url, function() {
            window.location.hash = anchor;
      });
}

loadContentWithAnchor("principal", "principale.htm", "#voitureVedette");

});

</script>

In the script above, once the document has loaded and the DOM is ready, it will execute the loadContentWithAnchor function with the three arguments. This function will load the contents of the page specified in the url into the element specified by the id argument. Once the content is loaded, it executes the function that will scroll the page down to the anchor which is supplied in the third argument.

Your links to load content would act in a similar fashion.

The "$(function() { ... });" wrapper simply tells the jQuery to wait until the document has loaded before executing the instructions within the anonymous callback function.

Hi alien109,

If I understand correctly, it is impossible to achieve what I want using only javascript?

Yes, the methods I described both use JavaScript to achieve what you are looking for. The jQuery solution is pure JavaScript, the other only involves the use of an iframe and JavaScript.
