Hi, ColinFine, in my javascript code. The prev.js is to do links with
URL preview. It is expected to show a preview box with linked
content. However, in my testing, prev.js can work on its own, when it
comes to using both script01.js and prev.js together, it doesn't
work. My question is how can I correct the code to make the preview
effect work under the script01.js. I have tried a few days. Any help
would be appreciated!

Quoting all your code may or may not be helpful. The problem is, that
you still haven't told us what problem you are seeing.
"Doesn't work" might mean anything from "Produces output which looks a
little different from what I expect" to "Crashes my browser".
What are you expecting to happen, and what actually happens?

There should be no relationship between the PeriodicalUpdater and the other Request. What do you mean when you say it 'breaks down' the preview code - what actually happens? You say 'the object is no longer referring to the gotopreview function', but I don't know which object you mean.

[Proto-Scripty] Re: How to correct the following code?
Hi, David, it seems that periodicalupdater send request first,
breaking down the preview code
setting new Ajax.Request. And the object is no longer refering to the
gotopreview function.
Because the firebug console returns the link that the
periodicalupdater request sever to update something,
just after that I move over any of the four elements (toplink), it
doesn't work.
Event.observe(window,'load',function(){
var elms = document.getElementsByClassName("toplink");
Event.observe(elms[0],'mouseover',function(ev){gotopreview(ev,
0);});
Event.observe(elms[1],'mouseover',function(ev){gotopreview(ev,
1);});
Event.observe(elms[2],'mouseover',function(ev){gotopreview(ev,
2);});
Event.observe(elms[3],'mouseover',function(ev){gotopreview(ev,
3);});
});
So, my question is, how can I do the following things.
1. PreriodicalUpdater sending data to Sever and Sever return
something;
2. Then, Event.observe(elms[x]) can keep doing its part of job without
being broken by preriodicalUpdater.
Is it my logic correct? or Wrong somewhere? Thanks for your help.

[Proto-Scripty] Re: How to correct the following code?
Hi SamuelXiao,
about the bind or bindAsEventListener method, it does not help in your
case.
Those two functions are used to force the value of 'this', but you are
not inside a class, and do not use 'this' inside the gotopreview
function.
I made testiung with given code, but there is some elements missing,
is it possible to have a live exemple to see the problem
