Quick Javascript tips to help you juggle and handle the known browsers.

Quick browser detection:

Edit: this quick browser detection should be used only to execute IE (or non-standard) Javascript. The way I use this is:

if (window.ActiveXObject)
{
// IE-only code
}
else
{
// standard code
}

window.XMLHttpRequest is implemented in IE 7 (but not in IE 6 and below). Thanks to Niko Bellic for the heads up.
IE:

if (window.ActiveXObject)

Mozilla/Safari:

if (window.XMLHttpRequest)

Getting event source element:

IE:

var oSource = event.srcElement;

Moz:

var oSource = event.target;

Cross-browser page redirect:

var sUrl = 'http://adavidchan.com';
setTimeout(function() {window.location.href = sUrl;}, 1);
