Better way to call javascript function in a tag

Question

Which of the following ways is a better way to call a js function from an a tag?

<a href="javascript:someFunction()">LINK</a> 

OR

<a href="#" onclick="someFunction();" return false;">LINK</a> 

I have seen this question here, but it says <span onclick="someFunction()"> is a better option. But due to some reasons I have to use <a> links.

EDIT: I am looking for a cross browser & cross platform solution which should work on androids & iPads too.

Answer 1

Neither is good.

Behaviour should be configured independent of the actual markup. For instance, in jQuery you might do something like

$('#the-element').click(function () { /* perform action here */ }); 

in a separate <script> block.

The advantage of this is that it

1. Separates markup and behaviour in the same way that CSS separates markup and style
2. Centralises configuration (this is somewhat a corollary of 1).
3. Is trivially extensible to include more than one argument using jQuery’s powerful selector syntax

Furthermore, it degrades gracefully (but so would using the onclick event) since you can provide the link tags with a href in case the user doesn’t have JavaScript enabled.

Of course, these arguments still count if you’re not using jQuery or another JavaScript library (but why do that?).
