How can I disable an anchor href with target _blank?

Question

I have this HTML line:

<a href="<%url%>" target="_blank">link</a>

Where <%url%> is a token I have to replace with a value that produces the click to do absolutely nothing. Note the anchor is in an iframe with the top same domain.

Consider:

1. I really do have to use an anchor
2. I have tried with the values # and javascript:void(0) but since the target is _blank they change the top.location.href to the iframe window.location.href so the iframe is loaded as the top window
3. I can't modify the HTML except for the token
4. No jquery

Answer 1

I found the way:

javascript:void(this.onclick=function(){return false;})

Answer 2

If you can put any string into the token, then make it end the href, then also include an onclick that cancels the click. Try replacing the token with this:

#" onclick="return false;

Answer 3

Can you add attribute

onclick="return false;"

?
