Perform a split on AttributeResource tag

Question

I have a WCM HTML component, and the value stored inside [AttributeResource attributeName="myKey" separator=","] is a comma separated String.
When rendered on its own, I get the following output on my HTML page ..

8,9,10,10.5,11,11.5,12,13 

However, when I try to split it on ,, it only gives me the first element i.e 8
How can I split this properly?

<script>
var keySplit = String([AttributeResource attributeName="myKey" separator=","]).split(',');
alert(keySplit);
</script>

Answer 1

Used a hidden input element to temporarily store values ..

<input type="hidden" id="myKeyTemp" value="[AttributeResource attributeName="myKey" separator=","]" />

<script>
var arrayOfValues = document.getElementById("myKeyTemp").value.split(',');
</script>
