I found it myself
here is the html code
<html><head></head><body>
<script language="javascript">
function bob(param1)
{
document.location.href=param1;
//return 123;
}
</script>
<a href="javascript:bob();">BOB href</a>
<br/>
<a href="#" onclick="bob()">BOB onclick</a>
</body></html>
and the C++ code
nsCOMPtr<nsIScriptGlobalObjectOwner>
theGlobalObjectOwner(do_GetInterface(mWebBrowser));
if (theGlobalObjectOwner) {
JSFunction* jsf;
nsIScriptGlobalObject *theGlobalObject ;
theGlobalObjectOwner->GetScriptGlobalObject(&theGlobalObject);
nsIScriptContext *theScriptContext =theGlobalObject->GetContext();
nsIPrincipal *thePrincipal = nsnull;
PRBool IsUndefined;
nsString theReturnValue;
nsresult rv =
theScriptContext->EvaluateString(NS_LITERAL_STRING("bob('http://www.yahoo.fr');"),
nsnull,thePrincipal, "", 1, nsnull, (nsAString &)theReturnValue,
&IsUndefined);
