I downloaded a javascript file that works GREAT. It shows and hides div's in the code on demand. My problem is that in my code the divs in question are forms that are submitted. The handler for the forms is the same page. So the first time I visit the page all the sections are hidden. I expand a div, add some information and submit. Then the page refreshes and all divs are hidden again. I have to reexpand the div again to continue my work. Not a HUGE deal except when I have a ton of data entry to do.

So I have a plan. I have created a table in the data base to hold a 1/0 value. I want the javascript that shows the sections to simply check the table. IE if the page is loaded, check the database to see which sections should be hidden and which should be visible.

I THINK the place to add it is the fuction called "showhide" on line 53 but I'm not sure if that's correct nor do I have any idea how to make it accept the value from the database.

Whew! I hope I made that clear. Below is the code for the javascript and the code of the webpage in question. Can anyone help?



//** Animated Collapsible DIV v2.0- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com.
//** May 24th, 08'- Script rewritten and updated to 2.0.
//** June 4th, 08'- Version 2.01: Bug fix to work with jquery 1.2.6 (which changed the way attr() behaves).
//** March 5th, 09'- Version 2.2, which adds the following:
//1) ontoggle($, divobj, state) event that fires each time a DIV is expanded/collapsed, including when the page 1st loads
//2) Ability to expand a DIV via a URL parameter string, ie: index.htm?expanddiv=jason or index.htm?expanddiv=jason,kelly

//** March 9th, 09'- Version 2.2.1: Optimized ontoggle event handler slightly.
//** July 3rd, 09'- Version 2.4, which adds the following:
//1) You can now insert rel="expand[divid] | collapse[divid] | toggle[divid]" inside arbitrary links to act as DIV togglers
//2) For image toggler links, you can insert the attributes "data-openimage" and "data-closedimage" to update its image based on the DIV state

No, the place to do this would be part of the init() function.

Have it *call* the showhide() function as appropriate.

But other than that, you probably have the right idea. You could do it more simply if you only wanted one <div> to be opened up each time you return to the page, but if you might need several open then your concept makes sense.

Resolved this by using JQuery, which works with a lot less code and its sexier! JQuery is opening up a whole new world to me.
