getElementsByTagName() - Compact Implementation of the Method

Community News

The method returns a list of elements with the given tag name. Here is a compact crossbrowser implementation that will reduce your code immensely.

Another more useful.

function $tag(tagName, from) {
return (from || document).getElementsByTagName(tagName);
}

// $tag("li");
// $tag("li", document.getElementById("ULID"));

"compact crossbrowser implementation"

Whooo, you've just discovered aliases. Next time please try harder.

how did this post from the past get featured? ive also got a killer javascript function:

function $hello() {
document.writeln("Hello world! I suck!");
}

Not only this post is a waste of time and his author presumptuous, but he also manages to get it wrong.

When making an alias you DO NOT wrap it in a function ! It introduce unnecessary overhead, just keep it simple :

var $tag = document.getElementsByTagName;

This will do the trick and his much better than your "cross-browser implementation" of a function which as always worked everywhere...

i find this post so amusing especially with this snippet by wow

function $hello() {
document.writeln("Hello world! I suck!");
}

it is cross browser too! LOL :D
