Question

 <div class='unsubscribe'><a id='us$id' href='#' onclick='subscribe(u,$id);'>
<img src='/unsubscribe.jpg' alt='unsubscribe' /></a></div>

onclick how do i change the first parameter in the onclick function to ‘s’? So the next time it will look like this.

<div class='unsubscribe'><a id='us$id' href='#' onclick='subscribe(s,$id);'>
<img src='/unsubscribe.jpg' alt='unsubscribe' /></a></div>

Answer 1

Instead of setting onclick in your HTML do it with Javascript soon after. I’m assuming you’re echoing all your code as a double quoted PHP string because of 'us$id':

<div class='unsubscribe'>
    <a id='us$id' href='#'>
        <img src='/unsubscribe.jpg' alt='unsubscribe' />
    </a>
</div>
<script type='text/javascript'>
    document.getElementById('us$id').onclick = function(){
        // Subscribe u
        subscribe(u, $id);

        // Set all future clicks to subscribe s
        this.onclick = function(){
            subscribe(s, $id);
        };
    };
</script>
