Jquery实现列表项的快速检索

<input type="text" id="shopSearchInput" />
<ul class="list-style shop-address">
<li data-word="北京市朝阳区">北京市朝阳区xxx路xxx街道</li>
<li data-word="上海市浦东新区">上海市浦东新区张江镇xxx弄xxx号</li>
<li data-word="广东省深圳市">广东省深圳市xxx路xxx号</li>
</ul>

$('#shopSearchInput').bind('keyup',function(){
var words = $(this).val().replace(/\ +/g,"\\ ").replace(/\'/g,"\\'").replace(/\#/g,"\\#");
if (!words){
$('.shop-address>li').show();
return;
};
$('.shop-address>li').show().filter(':not([data-word*='+words+'])').hide()
})
