Using js within a link

[JackD]

I wish to link to a popup window for a login box.
Currently using pro, and with this code to open a new window :

{code:"Log in",url:"/login.asp","format":{"size":[18,100]},"target":"new"},

However, I wish to use an onclick to an existing window function like so :

onClick="return logwin(this.href)"

Is it possible to integrate that into the url code?

Cheers!
