How can you create an XMLHttpRequest under Internet Explorer 6?

Answer 1

In all modern browsers, you can create a new XMLHttpRequest object using the following code:

var request = new XMLHttpRequest()

However, if you need to also support internet Explorer 6 and older, you need to extend your code like this:

if (window.XMLHttpRequest) {

//Firefox, Opera, IE7, and other browsers will use the native object

var request = new XMLHttpRequest();

} else {

//IE 5 and 6 will use the ActiveX control

var request = new ActiveXObject("Microsoft.XMLHTTP");

}
