Re: [Zope] Check for JavaScript:
Advice: client issues should be dealt with on client side. Great I agree completely, except if the client has Java/JavaScript turned off it is pretty darn difficult to have client issues dealt with on client side!!

Re: [Zope] Check for JavaScript:
[Daniel Rusch] | Hey all, | | Is there a way from zope to check to see if a user has Javascript | enabled Well, you may be able to set a cookie, with JavaScript, and then on the next page load, check for that cookie via REQUEST.. I.e.: On page 1, have a JavaScript command that sets a cookie (don't rembember how, from the top of my head); and subsequently, check for this cookie on the next page: * Use JavaScript to set a cookie on a page * Then (optionally) refresh to a new page, and test for the cookie. Or just have this feature on a front page or something similar.. Hmm, come to think of it, there may be an easier way (presuming the user hasn't turned images off): Enter a tag, something like this: script type="text/javascript" // !-- document.write( 'img src="http://www.yourhost.com/js-test/session/cookie_session_id"' ); // -- /script Oh, and there's the obvious (and cleaner?) way of embedding a script tag with a refresh request, something like: script type="text/javascript" // !-- document.location = 'http://www.yourhost.com/javascript-index.html'; // -- /script HTH. -Morten ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Check for JavaScript:
To expand on Peterson's idea, this is what I've used to test java script
and cookies. Instructions at the top of the page instruct the user to
reload to get accurate readings (for cookies) see:
http://linux.library.appstate.edu:8080/Zope_Server/Forms/SAAT/Proxy/
A page I'm working on to trouble shoot user problems when using our
library proxy service. There is a hidden input in the if statement of
the javascript, I have not tested to see if it sets that value every
time the page loads or not anyway. One problem with the trouble
shooting page is user's cache settings and when to reload pages. The
actions for the submit buttons have not been created yet.

PS. Is there a way to read the client's proxy setting directly?
