Advanced scripting - help available?

Advanced scripting - help available?

I have seen some sample scripts in "Tips and Tricks" area of Creator Help Center, and become very interested.

For example, the "subform" workarounds, which use advanced scripting to define functions.

One function is this:
(((
"<a href= '#' onclick=window.open('/showForm.do?zc-appname=meeting-tracker&zc-formname=Add_Meeting_Attendance
&link=true&sharedBy=" + zoho.adminuser) + "&meetingid=") + ID) + "&nexturl=javascript:window.close();','_blank','
width=650,height=420')>Add Attendance

When I want to use this kind of scripts in my applications, I inevitably want to understand them.

Where do I get any help in understanding scripts like the above?

It looks a little like normal HTML scripts within the (), but it is not exactly following HTML syntaxes.

Please enlighten. Thanks!
