Hi all,
Thank you John for your quick reply to my previous email. I've tried
out both of your suggestions below. It still does work. I might have
done something incorrectly as I am very new to these stuffs. Here are
the steps that I've taken:
I can't really tell you off the top of my head whether the javascript you
are using is correct - it could be that that is causing the problem.
1) I create a file called openMe_js with JavaScript function. Then, I
add it to the same dir as htmlPreview. The function looks something like:
script language="javascript"
!--
function openMe(URL){
window.open(URL,"","toolbar,status,resizable,menubar");
}
//--
/script
This bit looks ok.
BTW, I've put this code directly in htmlPreview.
Right. Then you won't need to do any of the other steps. I expect the
problem is with the javascript itself.
John

Hi Zopistas,
Happy New Year!
I'm working with SiteSummary and would like htmlPreview to grab the URL
and open it up in a new window. It's not working correct. I'm unsure
how Zope handle javascript either.
Zope handles javascript in the same way it handles html - it just sends
it to the client and let's the browser figure out what to do with it.
DTML, on the other hand, is interpreted beforehand, and the results are
sent to the browser.
Any help is greatly appreciated.
Below is my htmlPreview. I also tried to put the javascript function
(I'm new to js as well) in a file and import it to the same directory as
standard_html_header. Then I add SCRIPT LANGUAGE="JavaScript"
SRC="openMe.js"/SCRIPT to stand_html_header. That doesn't work
either. By the way, js doesn't seen to work well in Zope. I could n't
find much info on-line.

PA href="javascript:openMe('dtml-var url html_quote')"dtml-var linktext
html_quote/A
My understanding of what happens when this link is traversed is that the
browser calls the javascript function 'openMe(...)', which should already
defined in the page. It doesn't attempt to fetch anything from the server
with that URL.
So what you need to do is ensure that htmlPreview include the function
openMe by either including the code into the html document like this:
script language="JavaScript"
dtml-var name="openMe_js"
/script
(note that I've replaced the dot in openMe.js with an underscore, as
objects with dots in there ids need to be quoted to be used, and
1) I've forgotten how to do it
2) Searching through the documentation has given me a headache
)
...Or do what you did before:
SCRIPT LANGUAGE="JavaScript" SRC="dtml-var
expr="openMe_js.absolute_url()""/SCRIPT
Use the absolute_url() method, so that the browser is sure of getting the
right url for the script (which may have been your problem before).
I'd use the first method as you can at least eyeball the html output of
htmlPreview and see if the openMe function has acutally been include,
before having to use whatever passes for javascript debugging in your
browser.
HTH,
John

[Zope] Splitting ZSQL results across pages
I'd like to split the output of a ZSQL query across different instances of a page in the same fashion as zope.org does with ZCatalog output, but I can't for the life of me find any documentation on how it's done. Does anyone know the magic incarntations or where the documents are?

None I can think of off hand... Right. I'm going to consider it a bug and submit it to the collector as soon as I can research a potential patch.
