Client-side script for detecting NS6.x and IE5.x without using the navigator object’s properties
The navigator’s object properties are the most common technique used for browser detection.
In this post, I am just trying to find an alternate way to do browser detection.
A logical alternative would be to use the document object and try to find functions or properties that exist in one browser version but not on another.
For example:
document.getElementById is available for IE5+ or NS6+
document.all is available for IE4+
So, one possible solution would be:
if (document.getElementById) { // browser is IE5+ or NS6+
if (document.all) { // IE4+ only
// browser is IE5+
} else {
// browser is NS6+
}
}
Wondering how this can be useful? Well, who knows if this might come out as one of your interview questions. ;p
