Rails spinoffs - Aug 2005 - using the evalScript option on Ajax.Updater

Hi all,

I''m having trouble with the evalScript option on the Ajax.Updater. 
I''ve
removed everything except for the ajax call and a simple alert to try
and debug it.  It doesn''t appear that the regex is finding my JS in the
response...

I''m doing an update request and the response is coming back correctly
to
the updateConent function as this string:

<script language="Javascript">
alert("fdsfa");
</script>

But the scripts var inside of updateContent is still coming out as null.
Thus, obviously, my alert isn''t being run, because it doesn''t
think it''s
a script.

My regex is a little rusty, so I''m not quite sure what the
":" does in
the ScriptFragment variable it''s using to parse out JS code to then
eval.

Any tips?
Thanks much!

Rahul

How exactly are you making the Ajax.Updater call? Did you mean evalScripts 
instead of evalScript? If you left the ''s'' off the end in your
code, then
that is probably the problem.

Haha, no, I do have the key name spelled correctly, thanks though :-)

 

I changed my JS that is returned by the server to be all on one line and
it worked.  Very strange, as I thought one of the "img" options on the
regex was there to make line breaks not matter.  I''m in the latest
firefox.  Anyone else had that problem?

 

On a related matter - I actually want a slightly different behaviour.
If the form submit is ok (as decided by the server), then I want it to
do as normally and update the content with what I send back.  If my biz
logic finds errors in the form submit, I just want to run some
javascript (that flags certain fields), and NOT replace the content.
That''s a different enough behaviour that I''m going to write up
my own
subclass to try and do that tomorrow.  I didn''t see any easy way to
hack
that with the existing version.  Anybody got a tip?

 

Thanks,

 

rahul
