Question

I currently making a filebrowser. If the user clicks on a link to a file a little window open and asks for options (like download and view). I’ve done this using the onclick attribute. If I click on the link the javascript is executed, but after this the url specified in href opens. What I’m trying to do is: If you click the link javascript get executed and forwards you eventually. But if the link gets rightclicked the “copy link location” should still be available.
I’m thinking of solving this by blocking the forwarding scriptside. So if the link gets rightclicked no javascript is executed and you can copy the link location. But if you left click the link the javascript is executed and the link is not opened.
Is that possible with javascript, or is there any other way of achieving this behavior?

Answer 1

In order to prevent the link executing, one way is to let the “onclick” method return false.

For example:

<a href="http://..." onclick="return clickfunc()">...</a>

If clickfunc() returns false, a click on the link will not direct to “http://…”

Although you are probably handling it more like

<a href="http://..." id="somebutton">...</a>
<script>
document.getElementById('somebutton').onclick = function() { 
      ... 
      else { return false; }
};
</script>
