复制代码 代码如下:

$(document).ready(function () {

var locurl = location.href;

var start = locurl.indexOf("?");

var end = locurl.length;

var tempstr = locurl.substring(start + 1, end)

var temp = tempstr.split("=");

var parm = temp[1] - 1;

$(".ny_leftc_ul ul li").eq(parm).find("a").addClass("newtxz");

});
