JS通过URL参数高亮对应菜单项的实现

$(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");
    });
