Open a node link in a div with an include

Hello,
I built a tree and results are loading in a frame with :
tree.attachEvent(“onClick”,function(id){
document.getElementById(‘fra’).src=“organism.php?id=”+id;});
It’s working good.
Now i try to load results in a div on the same page with an “include” and i can’t find the solution.
Can you guide me ?
Thank you.

Hello Darya,
I found this solution, and it works :

tree.attachEvent("onClick",function(id){	
        function getXMLHttpRequest() {
	var xhr = null;
	if (window.XMLHttpRequest || window.ActiveXObject) {
		if (window.ActiveXObject) {
			try {
			xhr = new ActiveXObject("Msxml2.XMLHTTP");
			} catch(e) {
			xhr = new ActiveXObject("Microsoft.XMLHTTP");
			}
		} else {
			xhr = new XMLHttpRequest(); 
		}
	} else {
		alert("Votre navigateur ne supporte pas l'objet XMLHTTPRequest...");
		return null;
	}
	return xhr;
	}
function request(callback) {
var xhr = getXMLHttpRequest();

xhr.onreadystatechange = function() {
	if (xhr.readyState == 4 && (xhr.status == 200 || xhr.status == 0)) {
		callback(xhr.responseText);
	}
}
xhr.open("GET", "organism.php?id="+id, true);
xhr.send(null);
}
function readData(sData) {
	document.getElementById("my_div").innerHTML=sData;
}
request(readData);
});

Thank you for your help.

You are welcome!
