Check if checkbox has been checked?

[kanala]

How would I check if a check box has been checked. The name of the form is "return" and the name of the checkbox is "agree".Is this how you do it?

function checkme() {if(document.forms['return'].Agree == null){alert('Please read the policies and tick the checkbox');return false;}else{return true;}}

I'm nor sure, but until someone who knows the right answer, you can check out my gues.

if(document.form_name.checkbox_name.checked == true){   //The checkbox is checked}

<script type="text/javascript">  function checkBox(check) {	if (check) {	  alert("Yes");	}	else {	  alert("No");	}  }</script><input type="checkbox" onclick="checkBox(this.checked)">

<script type="text/javascript">  function checkBox(check) {	if (check) {	  alert("Yes");	}	else {	  alert("No");	}  }</script><input type="checkbox" onclick="checkBox(this.checked)">

But the problem with onclick is that once you uncheck the box, it will still work. I need to know how you can find out if the box is checked.

Sorry but it works now, it'e because I wrote == false but it only works when you do ==false (no space).Thanks

The space doesn't matter. You should use the .checked property to determine if a checkbox is checked.
