Hello… Roadblock. Please help.

Here is a good one for you… Tks in advance.

How to set-up Crony to schedule clicks on ‘value=”GO”‘?

Where:
<input type="button" id="create-snapshot" class="btn" value="GO">

or:

<script>
jQuery(function(){
   jQuery('#create-snapshot').click();
});
</script>
<input type="button" id="create-snapshot" class="btn" value="GO">
