checkbox

[Anon]

ok, sorry this may be a bit of a javascript question - but hey, it want be the first !!

I am looking to do a multiple checkbox checker thing (like hotmail). I have code to check all but I want it to uncheck all also:

Here is my attempt, its not working though ??

<script>
function check()
{
temp = document.main.elements.length ;
var c=0;
for (i=0; i < temp; i++) {
if( document.main.elements.checked=1😉 { c++; }
}
if(c !== 0) {
for (i=0; i < temp; i++) {
document.main.elements.checked=1;
}
} else {
for (i=0; i < temp; i++) {
document.main.elements.checked=0;
}
}
}
</script>

<a href="#" onclick="check()">ALL</a>

any ideas ???

Here's what I use for a mp3-browser/streamer/download thing I wrote. Change both occurences of "mp3" to whatever the name of your form.

function select(x) {
for(i = 0; i < document.forms["mp3"].elements.length; i++) {
var j = document.forms["mp3"].elements;
if(j.type == "checkbox") {
j.checked = x;
}
}
}

Call it like this to check them:
<a href="#" onClick="select(true); return false">All</a>
Call it like this to uncheck them:
<a href="#" onClick="select(false); return false">None</a>

And while I'm at it, you can specify the name of the checkboxes you want the function to alter if you change if-statement to something like this:
if(j.type == "checkbox" && j.name == "namegoeshere[]")

And if you're really in the mood, you can quite easily make a function that inverts the selection...

Cheers sp0ck, I was hoping to use only one link that would toggle on and off, but on off if everything was still selected - if you know what i mean.
anyway i just settled for the 2 link method.
cheers...
