call javascript function on hyperlink click

Question

I am dynamically creating a hyperlink in the c# code behind file of ASP.NET. I need to call a JavaScript function on client click. how do i accomplish this?

Answer 1

Neater still, instead of the typical href="#" or href="javascript:void" or href="whatever", I think this makes much more sense:

var el = document.getElementById('foo'); el.onclick = showFoo;   function showFoo() {   alert('I am foo!');   return false; }  <a href="no-javascript.html" title="Get some foo!" id="foo">Show me some foo</a> 

If Javascript fails, there is some feedback. Furthermore, erratic behavior (page jumping in the case of href="#", visiting the same page in the case of href="") is eliminated.
