$("#filter").keyup(function(){ //按键
	var filter; //过滤词
	var showResult=[]; //结果数组
	filter=$(this).val(); //根据文本框的值获得过滤词
	$("#result").html(""); //清空结果列表
	$.each(js_content,function(){ //遍历数组，
		if(this.substring(0,filter.length)==filter){//截取数组里的label的指定长度(长度为过滤词的长度)
			showResult.push(this);//如果结果一致，则讲此数组放到showResult
		}
	});
	for(var i=0;i<showResult.length;i++){ //遍历结果数组，放在结果列表
		$("#result").html($("#result").html()+"<ul>"+showResult[i]+"</ul>");
	}
})
</script>
</html>

希望能给大家抛砖引玉~
