給個小執行個體，注意在IE下的，沒考慮相容性，把以下代碼拷貝到文本中，改成test.html就可以了

<a href="#" onclick="clearNewMessageRemind();return false;">Stop flash</a><script type="text/javascript">var newMessageRemind={_step: 0,_title: document.title,_timer: null,show:function(){var temps = newMessageRemind._title.replace("[ ]", "").replace("[New Message]", "");newMessageRemind._timer = setTimeout(function() {newMessageRemind.show();newMessageRemind._step++;if (newMessageRemind._step == 3) { newMessageRemind._step = 1 };if (newMessageRemind._step == 1) { document.title = "[ ]" + temps };if (newMessageRemind._step == 2) { document.title = "[New Message]" + temps };}, 800);return [newMessageRemind._timer, newMessageRemind._title];},clear: function(){clearTimeout(newMessageRemind._timer );document.title = newMessageRemind._title;}};newMessageRemind.show();function clearNewMessageRemind() {newMessageRemind.clear();}</script>
