求教我点击所有服务订单时刷新了一下颜色没有改变，怎么使点击的颜色改变，没点击的颜色还原。是不是要用无刷新的。

	<li style="background:#2479a5;" onclick="search2()">进行中的订单</li>				<li  onclick="search3()">所有服务订单</li>

    function search2(obj){	    	 var state = 0;       		var url = "{:U('/addon/Order/Member/lists')}"+"&state="+state;				window.location.href = url;  							}            function search3(obj){	    	//var state = 1;      		var url = "{:U('/addon/Order/Member/lists')}";				window.location.href = url; 			}

<script type="text/javascript">		$(function(){			$(".load ul li").click(function(){				// $(".load ul li")				$(this).css("background","#2479a5").siblings().css("background","#4ab3e9");				var n=$(this).index();				$(".mem .list_bg").hide();				$(".mem .list_bg").eq(n).show();			})			$(".page_cen .pg").click(function(){				$(".page .pg").css({"background":"#fff","color":"#4c637b"});				$(this).css({"background":"#4ab2e9","color":"#fff"});			})			var len=$(".list_record").length;			$(".record_num span").text(len);		})</script>
