Loading Javascript Arrays with ZSQL Method
Hi all, It is possible to load a Javascript array using data from a ZSQL Method? Maybe some of you can give me a better way of doing this without using Javascript. I just want to create a dynamic drop down menu that users can select from and be able to display contents gather from a database query according to their selection. For example, if a user select category A. Then it will display all items for category A pulled from a database column. if select category B, then display all B items, etc. Thanks in advance, Mike --
You will most likely have to use the results of your ZSQL query to generate Javascript code that contains the correct array data. Mike Doanh Tran wrote:

Not at run-time, of course, but it's quite simple to do, say in Page Templates... <html> ... <script ...> .. js_array = [ <span tal:repeat="array_elt container/sql_method" tal:omit-tag=""> <span tal:replace="array_elt">1</span><span tal:condition="not:repeat/array_elt/end" tal:omit-tag="">, </span> </span>] .. </script> .. the rest of your page </html> Or a similar thing in DTML. (I have to jump through a few hoops in PTs because the output can't be XMLish.) You'll pardon me if this isn't what a JavaScript array looks like. I didn't bother to look it up.

You should take a look at how it's done with CSS. See http://www.meyerweb.com/eric/css/edge/menus/demo.html It's easy enough to generate the unordered list of links it uses to make the menus. It only works in Mozilla-based browsers at the moment, though you might be able to find more general ones if you look more than I did. --jcc
