How to add a onclick attribute to a list of checkboxes?

Question

I have this array for checkbox:

array(
        'name' => __('Latest Product',''),
        'desc' => __('Select if you want to display latest product',''),
        'id' => $prefix . 'checkbox',
        'type' => 'checkbox',
        'std' => ''
    )

I want to add an attribute for onclick="chk(electronics, this.checked);" on this.

How can I do it?

Answer 1

Store the ID in a variable, and access that variable in a JavaScript:

<script>
document.getElementById("<?php echo $checkbox_id; ?>").onclick = function() {
    chk(electronics, this.checked);
}
</script>

You can also collect multiple IDs in an array and run through that array later in your script. But avoid the onclick attribute in markup, this is bloat and bad code style. :)
