Simple checkbox problem

[Berras]

Apologies in advance my javascript is not great.

I want to create a script to cycle through a number of checkboxes to disable them. The best I can do is:

for(i=0;i<20;i++) {
vax x = document.forms.myForm.box_;
x.disabled=true;
}

Where the checkboxes are named "box_0, box_1, box_2..." etc.

Sorry, that supposed to read:
var x =...

You're close... but have a few minor errors. Try this instead

for (var loop=0; loop<20; loop++) {
	document.forms['myForm'].elements['box_' + loop].disabled = true;
}

I removed the assignation, as it was not really needed.

Hope this helps,
Dan

If you don't want to limit it to a specific form, you can hit the whole page by doing the following.

function disableCheckboxes()
{
  // Using the DOM method, set a variable (array) to be all
  // input tags on the page.
  var inputs=document.getElementsByTagName("input");
  var i;
  for (i=0; i<inputs.length; i++)
  {
    // Only disable the inputs if they are checkboxes.
    if (inputs[i].type=="checkbox")
    {  inputs[i].disabled=true; }
  }// end for i
}// end disableCheckboxes
