1.1跳转页面同时添加activer

js

$(document).ready(function(){
  [location.pathname]
-- 返回URL的域名后的部分。例如 http://www.dreamdu.com/xhtml/list   返回/xhtml/list
**pathname**，中文"路径名称"

    var local = window.location.pathname; //获取url
    localName = local.split("/");  //去掉'/' localName([1])表示第一个xhtml
           $e = $(".bottombox").find('.'+ localName[1]);
           $e.addClass('activer').siblings().removeClass('activer');
// 特殊情况，但第一个相同，第二个不等于conbine时，做判断
    if(localName[2] != 'combine'){
         $e.addClass('activer').siblings().removeClass('activer');
    }else{
        $(".li2").addClass('activer').siblings().removeClass('activer');
    }    

})

1.2跳转页面同时添加activer并传入参数

functionn go(url){
location.href = url + '?invitation=' + $("#dealerName").val();
}

<a href="javascript:void(0);" onclick="go('/ctive/aaaa')" data-url="/ctive/aaaa">aaaa</a>
<a href="javascript:void(0);" onclick="go('/ctive/bbb')" data-url="/ctive/bbbb">bbbb</a>
<a href="javascript:void(0);" onclick="go('/ctive/cccc')" data-url="/ctive/cccc">cccc</a>

$('.left_nav_act a').each(function () {
        if ($(this).attr("data-url") == String(window.location.pathname))
            $(this).addClass('activerA');
    });
