Can't change/disable Draggable Containment after setting to parent
[0Replies]

MAY have actually found a bug here...
2. $(targetObject).draggable({
3. drag: function (e, ui) {
4. $("#rptSlideLayerEdits_ctl0" + layernum + "_tbXPos").val(theLeft);
5. $("#rptSlideLayerEdits_ctl0" + layernum + "_tbYPos").val(theTop);
6. },
7. stop: function (e, ui) {
8. saveLayer(currentLayerNumber);
9. },
10. containment: "parent"
11. });
So, this is the code that sets up the draggable. I have a little lock icon, when you click it, it runs this function:
2. function disableLayerConstraint(){
3. $(".layerCons").attr("src", "images/mb_unlock.png");
4. $(targetObject).draggable({containment: null });
5. }
I've tried null,"", and undefined to disable the constraint (there was no documentation on how to disable a constraint). Now everything works as expected, unless you drag it first. So, load the page, click the unlock, and I can drag it wherever I want. BUT, load the page, drag the object, THEN click the lock, it's still contained to parent.
Can anyone recreate this issue and confirm it's a bug?

I'm running the latest version of jQuery and UI.

Thanks!

strange animate behavior - jumps to random position before ending up in correct location

This is for a non-profit educational web resource mainly for teachers in schools so your help will definitely be hugely appreciated since I am the only web developer for this under-budgeted, highly-trafficked website!!

Basically, I have an arrow that points to the page that you're on. When you click on a new item, the arrow slides to show you what section you're on. Now, the arrow ends up in the right place, but everytime you change it, it seems to slide to the very left FIRST, and then it will go to the correct place. I've tried all sorts of tweaks and options to the code (and different browsers, etc etc) at this point... And everytime it has this funny behavior. Can anyone give me some good advise? This is so annoying...

Here is the stripped-down page
http://myhero.com/go/create/stack.asp

The only menu options that work are "Preview" and "Visitor Intro" so try clicking between those two items and you'll see what I mean.

THANK YOU

detecting a browser's back button

I'm sorry, I know (or think) this question is answered already on the board in a couple places - but I'm still new and I just can't wrap my head around this.

I have a jquery-powered "start page" that checks your log in and if successfull it slides in a "menu" of new places to go. The problem is, if you click back from one of the new places, the original "start page" looks as if you never logged in. You have to reload the page. Not very intuitive and this website is for kids. Now I've tried setting form field values with server session variables, javascript variables, etc etc but they all get reset when you click back. I've tried the "onunload hack" which I don't fully understand, and then read a bit about the onhashchange event which is from what I gather only compatible with HTML5 browsers...

So... is there no way to detect if the user is already logged in when they click the back button or am I not doing enough homework?

Thanks all for any help/insight you could provide...
