Checkbox arrays and Javascript

[Tanus]

I'm trying to perform the following (see here for an example, it shows it better ), with these extras...

When I click one of the parent nodes (one of those checkbox things) I want to fill each of the child nodes as checked. There's two easy ways to do this; by making them checked to begin with when they're hidden (but I'd prefer not to as then those checkboxes will still be sent with the form), or using a name without [] brackets in it, which will suck a bit because it's a lot easier processing all these checkboxes as an array on the other side of the server.

I've found the following bit of code about checkboxes, but I tried it a way I thought it might work and nothing happened, can anyone shed any more light on it?

The actual code for the checkboxes looks as follows (and works fine when using the form data in the action script)

PHP Code:


<form name="advancedsearch" method="GET" action="search.php">

        <!-- THE STALIN'S VISITOR'S BRANCH -->
        <div class="trigger" onClick="
        showBranch('stv_branch',document.advancedsearch.stv);
        changeCheckbox(document.advancedsearch.stva[0], true);
        ">
        <input type="checkbox" name="stv" value="stalin_visit">
        Stalins Visitors<br>
        </div>
        <span class="branch" id="stv_branch">
        <input type="checkbox" name="stva[]" value="person.name" checked>
        Name<br>
        <input type="checkbox" name="stva[]" value="stv.date" checked>
        Date<br>
        <input type="checkbox" name="stva[]" value="stv.start" checked>
        Start<br>
        <input type="checkbox" name="stva[]" value="stv.end" checked>
        End<br>
        <input type="checkbox" name="stva[]" value="stv.notes" checked>
        Notes<br>
        </span> 


The changecheckbox function merely toggles the paramater from true to false, but I don't know how to pass a checkbox that is part of an array... any pointers?

AFAIK the code you have should be work. That's quite strange that it doesn't. I had a quick look through 2 Java books to try and find anything to suggest otherwise, but I didn't find anything.

Im not surprised. Try a Javascript book.

I'm not sure that I completely understand your problem. But I think that it is with the HTML rather than the JS. Try checked=true. Might fix your problem. I had a lot of probelms with checkboxes a few months ago, can't remeber all the things I did to fix 'em.

Yes thats right, I'm a complete tool. But have a look at the time I posted that.

Yeah... That's a good excuse.

I found out the problem. Mozilla based browsers have changed the way form elements can be accessed to be more standards compliant. Microsoft doesn't of course. So I've had to change the way the bracket named elements are accessed.
