Question

So suppose I have this tag

<a href=""></a>

and then I make up some non-standard attribute

<a lol="haha" href=""></a>

If you ask why, well so that I can conveniently use that made up attribute in my javascript…

My question is…is there any possible negative repercussion of doing this….is there any good reason why I shouldn’t be doing this?

Answer 1

Browsers will almost universally handle custom attributes. And when I say universally, I mean even IE6.

Of course the standard way to do that is with:

<a data-lol="haha" href=""></a>

Which, since you’ve tagged with jQuery, I’ll mention can be read (even in IE6) with

$("a").data("lol");
