How can I disable HREF if onclick is executed

Question

I have an anchor with both HREF and ONCLICK attributes set  If clicked and Javascript is enabled  I want it to only execute ONCLICK and ignore HREF  Likewise  if Javascript is disabled or unsupported  I want it to follow the HREF URL and ignore ONCLICK  Below is an example of what I m doing  which would execute the JS and follow the link concurrently  usually the JS is executed and then the page changes     lt A HREF  http   example com no-js-login  ONCLICK  yes js login    gt Log in lt  A gt    what s the best way to do this   I m hoping for a Javascript answer  but I ll accept any method as long as it works  especially if this can be done with PHP  I ve read  a href link executes and redirects page before javascript onclick function is able to finish  already  but it only delays HREF  but doesn t completely disable it  I m also looking for something much simpler

I solved a situation where I needed a template for the element that would handle alternatively a regular URL or a javascript call, where the js function needs a reference to the calling element. In javascript, "this" works as a self reference only in the context of a form element, e.g., a button. I didn't want a button, just the apperance of a regular link.

Examples:

<a onclick="http://blahblah" href="http://blahblah" target="_blank">A regular link</a>
<a onclick="javascript:myFunc($(this));return false" href="javascript:myFunc($(this));"  target="_blank">javascript with self reference</a>

The href and onClick attributes have the same values, exept I append "return false" on onClick when it's a javascript call. Having "return false" in the called function did not work.

yes js login   function                 Your code here          return false          If you return false it should prevent the default action  going to the href    Edit  Sorry that doesn t seem to work  you can do the following instead    lt a href  http   example com no-js-login  onclick  yes js login    return false   gt Link lt  a gt
