View Full Version : Persist IE6 problem

01-22-2009, 08:38 AM
1) Script Title: Simple Menu Tree

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex1/navigate1.htm

3) Describe problem: http://www.idozo.org.php5-1.dfw1-1.websitetestlink.com/index.php

My problem is with the persist in IE6 and IE7. You'll notice that in IE6 when you click on the category title, the menu will open, but as soon as the page reloads the menu is closed again.

I can't get the menu open at all! The crazy thing is that I have the last menu set to open with rel="open" and it's still staying closed. I checked my cookie drawer and I have the cookie from the script, but IE is ignoring it.

I'm not aware of any common sort of situation on a single computer where you can run both IE 7 and IE 6 with cookies operational in both of those browsers. One browser or the other gets the cookie functionality. If you have two separate boot partitions or two separate machines, it could work as long as each browser were to be the primary IE browser in its boot environment.

What's your testing environment like?

I'm running IE6 only. My developer is running IE7 and the persist doesn't work with either computer.

It appears to be a conflict with mootools. Upgrade to v1.2.1, to do so just as a test, replace:

<script type="text/javascript" src="/media/system/js/mootools.js"></script>

on all pages, with:

<script src="http://ajax.googleapis.com/ajax/libs/mootools/1.2.1/mootools-yui-compressed.js" type="text/javascript"></script>

That should work OK with the caption script, and appears not to have the problem with the cookies in the tree menu script in IE 7 at least.

Be sure to clear your cache before testing the new pages.

If you decide you like the v1.2.1 of mootools, you may download your own copy, or continue to use the googleapis hosted version, that's what it's there for.
