If you're using a script (e.g. php) which could generate any number of checkboxes, it's more efficient to run through every element in the form and check it if it's a checkbox. Not that I remember how to do that, but I thought I'd point that out. =( |

You're been talking about the DOM in almost every JavaScript related thread lately but you rarely come up with an actually useful answer...
Anyway...
<form name="cboxform">
<input type="checkbox" name="cbox1" /> Checkbox 1
<input type="checkbox" name="cbox2" /> Checkbox 2
<input type="checkbox" name="cbox3" /> Checkbox 3
<input type="button" value="Select all" onclick="document.forms.cboxform.cbox1.checked=1; document.forms.cboxform.cbox2.checked=1; document.forms.cboxform.cbox3.checked=1;" />
<input type="button" value="Unselect all" onclick="document.forms.cboxform.cbox1.checked=0; document.forms.cboxform.cbox2.checked=0; document.forms.cboxform.cbox3.checked=0;" />
</form> |

I know you have to do it in Javascript, and I've search around a bit for free scripts, but none kinda worked  .
How could I select or unselect all checkboxes on a form with one click? |
