	Javascript help! got the code, need to reverse effects. Support Apolyton

This is the code:

At the moment, it disables checkboxes via a master checkbox.

But what I want it to do is ENABLE the checkboxes via the master checkbox.

Also, the master checkbox has to be a radio, or at least function like a radio.

Any help?

(and yes, I have tried coding forums and sites, I'm desperate to get this sorted out today!)

edit: code tags aren't working

=======================================
// The check box group is definded by the check boxes with a parent of the same title
// A check box with a parent node of the group title suffixed with 'f7_Master'
// is used to set the disable status of the other check boxes
// Example HTML Code for one group
//
//

//

//

//

//
// Master

//

// or to force the disabled group into a checked state of checked use
//
// Master

//

// or to force the disabled group into a checked state of unchecked use
//
// Master

//



// Each group is initialised from a onload event
//
// where

// All variable, function etc. names are prefixed with 'f7_' to minimise conflicts with other javascripts


var f7_cks;

function f7_DisableCBGroup(){
f7_cks=document.getElementsByTagName('INPUT');
for (f7_0=0;f7_0 if (f7_cks[f7_0].type=='checkbox'){
if (f7_cks[f7_0].parentNode.title.match('f7_Master')){
f7_cks[f7_0].parentNode.state=f7_cks[f7_0].parentNode.title.split('f7_Master')[1];
f7_cks[f7_0].parentNode.title=f7_cks[f7_0].parentNode.title.replace(f7_cks[f7_0].parentNode.state,'')
f7_Disable(f7_cks[f7_0])
f7_cks[f7_0].onclick=function(){ f7_Disable(this); }
}
}
}
}

function f7_Disable(f7_obj){
for (f7_1=0;f7_1 if (f7_cks[f7_1].parentNode.title==f7_obj.parentNode.title.replace('f7_Master','')){
if (f7_obj.checked){
f7_cks[f7_1].setAttribute('disabled',true)
if (f7_obj.parentNode.state=='CHECK'){
f7_cks[f7_1].checked=true;
}
if (f7_obj.parentNode.state=='UNCHECK'){
f7_cks[f7_1].checked=false;
}
}
else {
f7_cks[f7_1].removeAttribute('disabled')
}
}
}
}

	Full PM-box? Change here!

Set the checkboxes' initially to disabled. Set a script associated on the master checkbox's onclick handler. It checks the state of the master checkbox - if checked, enables other checkboxes, if unchecked, disables other checkboxes.

Yes, that's the simple way of doing it.

But then multiply this by 4 and you will face problems.

This form has 4 sections, and in each section are 2 checkboxes.

A section has to be enabled before the 2 checkboxes in the corresponding section are enabled for use.

Yeah, I can see it getting tedious, though still pretty simple. Copying and pasting sections of code plus some minor changes (names of elements) should do the trick.

	Tired of ads?

I said stuff it, and did some experimenting.

And lo and behold, it worked.

WOO!!

And I know about .05% of javascript.

edit: ok, code won't display, and I can't be arsed to work out why.

Now I just have to set it for the other 3 Options!

YEAH! Now I see where programmers get their kicks!
