上次看到國外那誰誰實現瞭Youtube的Instant搜索，據說花瞭三小時。
我笑瞭，我看瞭那篇文章後，自己花瞭三小時，實現瞭百度和優酷的Instant搜索體驗。
難點在於，鍵盤輸入的監聽。用瞭JQuery自帶的keyup函數，再加JS自帶的setTimeout函數，較好地實現瞭效果。

請輸入你想要搜索的關鍵字：<input id=”getKey” type=”text” /><a href=”#” id=”baidu”>百度</a> | <a href=”#” id=”youku”>優酷</a><br />
<p style=”overflow:hidden”><iframe id=”up” class=”show” frameborder=”0″ ></iframe></p>
