Question

Which technique is better:

<span onclick="dothis();">check</span>

or:

<span class="bla">check</span>
<script type="text/javascript">
    $('.bla').click(function(e) {} );
</script>

Are there any differences according to usability, performance etc.?

Thank you!

Answer 1

The second is better from a code quality standpoint since it is considered to be unobtrusive. I am not certain if either approach has measurable performance benefits.

My advice is to stick to the unobtrusive approach – it will save you a lot of time when you are doing maintenance down the road.
