play on tumblr

  var click = function(n) {
    var e = document.createEvent('MouseEvents');
    e.initMouseEvent("click",true,true,unsafeWindow,1,10,50,10,50,0,0,0,0,1,n);
    n.dispatchEvent(e);

マウスクリックをやっつけてるところはこの辺りか。

event.initMouseEvent(type, canBubble, cancelable, view, detail, screenX, screenY, clientX, clientY, ctrlKey, altKey, shiftKey, metaKey, button, relatedTarget);

event.initMouseEvent - MDC

unsafeWindow なのは、onclick なとこをクリックするためなのかな。あとscreenX, screenY, clientX, clientYってなんだろね。
