Native XMLHttpRequest in IE 7
Published on Tuesday, January 24th, 2006
The IE team has made a very wise decision to natively support XMLHttpRequest in IE 7. XMLHTTPRequest is the foundation of any AJAX usage, and I for one applaud the move to make it available without the demand for using ActiveXObject.
Using object detection, one can easily make your code backwards compatible as well:
var oXMLHttp;
if(typeof XMLHttpRequest != "undefined"){
/* Code for:
IE 7
Firefox, Mozilla etc
Safari
Opera
*/
oXMLHttp = new XMLHttpRequest();
}
else if(typeof window.ActiveXObject != "undefined"){
/*
Code for:
IE 5
IE 6
*/
oXMLHttp = new ActiveXObject("Msxml2.XMLHTTP");
}
