Forms "Check All" checkboxes

S

Steve

I've got a form with a lot of checkboxes set up in a table. I've found some
Java that will allow me to Check All / Uncheck All ... but it seems to only
work within the <td> </td> tags.

Is there a nonJava way to check all the checkboxes on a page? Or is there a
Java applet that will ignore the <td> tags and check everything in the
table?

Thanks for any help,
Steve

Aside from starting with them all checked? No, not really.

This is fairly trivial to do in javascript. Ask in comp.lang.javascript
after you have read their FAQ.

You can use the selected attribute on eact input tag:

Are you sure you're using a Java applet or do you mean a Javascript
function? Java and Javascript are pretty unrelated things.

If you want a simple Javascript function to select all checkboxes in
the current form try this in the <head> section of your page:

<script type="text/javascript">
function selectAll(x) {
for(var i=0,l=x.form.length; i<l; i++)
if(x.form.type == 'checkbox' && x.form.name != 'sAll')
x.form.checked=x.form.checked?false:true
}
</script>



In your form, just give the name 'sAll' to the checkbox you want to use
to run the function and use the onclick attribute to call it:

<form>
<input type="checkbox" name="sAll" onclick="selectAll(this)" /> (Select all)<br />
<input type="checkbox" name="a" /> (A)<br />
<input type="checkbox" name="b" /> (B)<br />
<input type="checkbox" name="c" /> (C)<br />
<input type="checkbox" name="d" /> (D)<br />
<input type="checkbox" name="e" /> (E)
</form>

If you use valid markup and it should work, and can be used from multiple
forms.

function? Java and Javascript are pretty unrelated things.

If you want a simple Javascript function to select all checkboxes in
the current form try this in SCRIPT tags in the HEAD section of your page:

function selectAll(x) {
for(var i=0,l=x.form.length; i<l; i++)
if(x.form.type == 'checkbox' && x.form.name != 'sAll')
x.form.checked=x.form.checked?false:true

Excellent, this works. Actually it toggles the boxes back and forth ... if
I mark about 10 things, then hit sellect all, those 10 things become
"unmarked" and the rest are marked. Not a big deal though.

I really appreciate your help. My javascript skills are nonexistant.

Change this:

x.form.checked=x.form.checked?false:true

to:

x.form.checked=true;

yep php will do a good job. I dont knwo sh^t bout html by the way so I dont
know if the syntax is correct but u should get the idea

This is a verry dirty way to do it but it works great

Juts place a link to urpage.php?action=checkall and rewrite ur html. The
advantage: no Javascript

<?php if ($_GET['action']=="checkall"){$dummy=" checked";}?>

and each box
<input type="checkbox" name="name" value="val"<?php echo $dummy; ?>>
will give
<input type="checkbox" name="name" value="val" checked>
or
<input type="checkbox" name="name" value="val">

:)
