Leave out the onclick attribute and use addEventListener
<https://developer.mozilla.org/en/DOM/element.addEventListener>.
Example:
var elem = /* the <a> element in question */;
elem.href = "javascript:void(0)";
// Note that this does not pass the listener as *text*, but as a
*function object* :)
elem.addEventListener("click", function (evt) {return
myScript.myFunction('text');}, false);
// Depending on where the previous line executes, you may not need
the myScript qualifier
Some deep background is given on http://wiki.greasespot.net/Security;
the gist of it as applicable to your situation is that GM scripts run in
a different context for security reasons, and there is no way for the
eval
<https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/eval>()
call implicitly used by the onclick attribute to resolve the object
correctly, since it's just not in scope at the time. The solution is to
use closures
<https://developer.mozilla.org/en/JavaScript/Guide/Closures> to capture
a reference to the object while attaching the event listener.
Make sense?

I have a user.js script which is modifying a link on a page from this:
<a href="...url...">...text...</a>
to this:
<a href="javascript:void(0)" onclick="return
myScript.myFunction('text')">...new text...</a>
Now, "myScript" is the main object in my user.js file. The problem is
that I get the following error message when I click on the modified
link:
Error: myScript is not defined
How do I get that link to invoke a function in my user.js file?
Thanks.

This is a test of the emergency signature system. Were this an actual
signature, you would see amusing mottos, disclaimers, a zillion net

However, this is only a test. «= tagzilla.mozdev.org
