tick the boxes

[WindAndWaves]

Hi Gurus

I am sorry to ask so many questions, but unfortunately, you are just such an
awesome source of knowledge that I can not help myself but ask lots. One
day, I hope to be able to answer other people's questions.

Here we go, I have the following function (I made it myself ...!)

function tic(form,a,z){
for(f=a;z;f++){
if(form[f].type=="checkbox"){
form[f].checked=true;
}
}
}

It is supposed to tick a range of tickboxes (e.g. 1-10 or 11-30), I want to
use a and z to identify the range.

I use the following to call the function:

<LABEL FOR="0">
<INPUT TYPE="checkbox" VALUE="0" NAME="0" CLASS="ix"
ONCLICK="tic(this.form,0,1);">
New Zealand Wide</LABEL>

However, even with a range from 0 to 1, it will tick all the boxes in the
form. Secondly, does anyone know how to make the reverse function? Can I
add a fourth variable that indicates whether the current tickbox is true or
false and then use this in the function?

I hope it all makes sense

Thank you once more for all your help

Hi Gurus

Gurus is on holidays, and isn't due back until after Christmas. Sorry.

The following is JavaScript, and as such is best addressed in a
JavaScript newsgroup, such as news://comp.lang.javascript

That's not to say that no one in alt.html can answer it, but in general
it is best to ask in a group specifically aimed at JavaScript.
Cross-posted and followups set.
