checkbox and ajax only showing value of on

[Orionsbelter]

Hi there, 

 

I'm currently using ajax to update the mysql database via onchange or onclick 

 

using checkboxes such as below:

 

 

<input type="checkbox" name="wac_non_bce" id="wac_non_bce" <?php if($cue_wac_non_bce=="1"){echo"checked='checked'";}?> onchange="changeData(this.value, 'wac_non_bce', '<?php echo"$add_prod_id";?>')" />

 

The this.value only returns 'on' when checking and unchecking the box; 

 

Which is for clear reasons not helpful at all 

 

Has any one come across this issue before?

By default, a checkbox value is "on" regardless if it's checked or not (if set the value property, that value will always be the same if it's checked or not). When a form is submitted and the checkbox is checked, the value is sent with the form. If it's not checked, the value is not sent at all.

 

For your script, you should test the checked property (not value). e.g. changeData(this.checked, ...

Also, it's better to use onclick event rather than onchange for older browsers.
