Hello Igor,
thanks for your reply!
But super.getOnClickScript() just returns null. Looking at Link's
code, I found out that the onClick code is created in method
onComponentTag(), and simply replaced by getOnClickScript() if that
doesn't return null.
But I found a solution:
protected CharSequence getOnClickScript(CharSequence url) {
StringBuffer buf = new StringBuffer();
buf.append("if (!window.confirm('Are you sure?')) return false;");
buf.append("location.href='");
buf.append(url);
buf.append("';");
return buf.toString();
}
The tricky part of generating the url is done already, and passed as
an argument. I already wondered before what url that might be, but it
turns out its just what I needed :)
