Question

I have some code which was developed on a Windows 7 computer and runs any Windows 7 compeer without any hiccups. I tried running it on my Mac and the program just stays on the loading page.

The program displays the bing maps view and loads a few things in order to get the location of a particular satellite. Now all the maths and stuff works but I think the problem lies here:

function getOrbitalElements()
{
TLE_Line1="";
TLE_Line2="";
pgTXT = "";
xmlhttp = null;
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
if (xmlhttp!=null)
{
    xmlhttp.onreadystatechange = stateChange;
    xmlhttp.open("GET",url,true);
    xmlhttp.send(null);
}

}

So is there any way that this can be changed to run on any browser? Thanks
P.S. If you need to see the entire code I’ll add it

There are no ActiveX objects on Mac. The following line won’t work:

xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

You could use XMLHttpRequest:

var xmlhttp = null;  
if (window.XMLHttpRequest) { // Mozilla, Safari, ...  
    xmlhttp = new XMLHttpRequest();  
} else if (window.ActiveXObject) { // IE 8 and older  
    xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");  
}  

if (xmlhttp != null) {
    ...
}

But if you are seeking best cross browser support I would recommend you using a javascript framework such as jQuery to perform your AJAX requests.
