Subj : trying to understand javascript calls

hello !
i've been trying to understand how javascript engine works and how
javascript calls work too for many days (and i don't understand anything).

i read two documentations : "javascript C engine embedder's engine" and "How
to embed js engine" from Brendan.
My need is : in my c++ app, when the web page is completely loaded, i 'd
like to execute successively all javascript scripts called in some DOM
nodes, and retrieve the new DOM each time it has changed.
I found some javascripts calls inside html "href" and some javascripts calls
elsewhere like "onClick=...".
For a javascript call in "href", i used "EvaluateString()" function. It
works one time only.
For a javascript call like "onClick", i tried  "EvaluateString()" but it
doesn't work.  I tried to follow the "embed js engine" documentation but for
me, some informations are lacking : FindEventTarget() ??? , NewEventObject()
???

As a matter of fact, all is nebulous : what 's a global object ? when should
i use js_evaluateScript() or js_callFunction() ???
what is a scriptGlobalObject ??? and so on....

It would be very nice if you can help me.

Thank's a lot.
