How would I check to see if a checkbox is checked or not with Javascript?

[Toni Howlett]

I just have a basic checkbox and I was going to add an onclick function to it... but I need it to do one thing if its checked and the other if not.

I bascially want to do if (checked) {} else {}

The check boxes do not currently have an id, but I can add one if necessary.


So again, how would I check to see if it is checked or not?

You don't need its id, the reference is available from the event instance.

If the element is checked, it will possess a checked attribute.

How do I do it tho?

[Bear Bibeault]

What have you got so far? Where's your code? What specific problems are you having with it?

And personally, I'd never attempt event handling without jQuery assist. Life is too short to deal with IE's proprietary madness.

[Toni Howlett]

I can say already, it does NOT need to work for IE.

I don't really have code relating to this - which is why i'm asking.

<form action="content/formAction.jsp" method="post" name="settings">

...

<input type="checkbox" name="importantLinks" onClick="changeDisplayOrder('importantLinksOrder')">

...

</form>

the content of my javascript isn't important. It will run half of it if you click the box to be checked or it will run the other half of it if you click the box to be unchecked.


and I have 0 experence with jQuery

document.formName.elementName.checked
document.getElementById("elementId").checked
