Fire analytics tag based on message event from window

Question

I have some code that checks to see what event data is being passed back from two different media players. The first player sends back play button clicked, but the second player sends back the data I want but it's I have to parse it and read it to see if it matches play and startPosition === 0.

Wondering if there is a better way to check both the players to see what data is being passed in. What I have just feels dirty.

function handleWindowMessage (e) {
    var originalEventData = e.originalEvent.data;

    if (originalEventData === 'play button clicked') { 
        _gaq.push('_trackEvent', 'Video', 'Played');
    }

    try {
        var parsedData = JSON.parse(originalEventData).data;

        if (parsedData && parsedData[0] === 'play' && parsedData[1].startPosition === 0) {
            _gaq.push('_trackEvent', 'Video', 'Played');
        }
    } 
    catch (ignore) {}
    finally { return; }
}


$(window).on('message', handleWindowMessage);
