How to parse parameters from JSON String using JS? [duplicate]

Question

I'm trying to parse a JSON String , but the parsed value is undefined . Here is jsfiddle

    <input type="submit" onclick=testJSON() value="Test"/> 
    <div id = "result">Test </div> 

<script> 
    function testJSON() { 

    var jsonString = '{"param1":"123","param2":"XXX78","param3":"11378"}'; 

    document.getElementById("result").innerHTML = (JSON.parse(jsonString)).param2;

    } 
</script>

Seems to work fine -> jsfiddle.net/q080hxp3/2

The code is working fine - the problem here is in JSFiddle, as it's set to just run the JS code when the document is loaded, so the function doesn't get registered - here's the relevant option:
