一个页面跳转到另一个页面的tab选项卡的指定页上

a页面是一个tab切换，b页面同样也是一个tab切换，目前想实现从a页面的tab“B”跳转的b页面的tab“B”

a页面代码：

<div class="company_department fr">
    <div class="notice_small_nav">
        <a href="#2" class="company_notice notice_nav_a">公司公告</a>
        <a href="#2" class="department_notice">部门公告</a>
    </div>
    <div class="company_content">
        <ul>
            <li><a href="notice.html#company">【公司公告喜讯】中标网再中5亿啥啥啥啥项目，呵呵 </a></li>
            <a href="notice.html#company" class="more">更多</a>
        </ul>
    </div>
    <div class="department_content">
        <ul>
            <li><a href="notice.html#department">【部门公告喜讯】中标网再中5亿啥啥啥啥项目，呵呵 </a></li>
            <a href="notice.html#department" class="more">更多</a>
        </ul>
    </div>
</div>

<script type="text/javascript">
    $(function(){
        $(".notice_small_nav a").click(function(){
            $(this).addClass("notice_nav_a").siblings().removeClass("notice_nav_a");                    
        });
        $(".company_notice").click(function(){
            $(".company_content").show();
            $(".department_content").hide();
        });//公司公告
        $(".department_notice").click(function(){
            $(".company_content").hide();
            $(".department_content").show();
        });//部门公告
    });
</script>

b页面代码（notice.html）

<script type="text/javascript">
    $(function(){
        var hash=window.location.hash||'';
        if(hash=='#company'){
            
            $(".company_content").show();
            $(".department_Box").hide();
        }else if(hash=='#department'){
            $('.company_notice_a').removeClass('current');
            $('.department_notice_a').addClass('current');
            $(".company_content").hide();
            $(".department_Box").show();
        };
        $(".notice_nav_a a").click(function(){
            $(this).addClass("current").siblings().removeClass("current");                    
        });
        $(".company_notice_a").click(function(){
            $(".company_content").show();
            $(".department_Box").hide();
        });//公司公告
        $(".department_notice_a").click(function(){
            $(".company_content").hide();
            $(".department_Box").show();
        });//部门公告
        $(".company_content .selectAll").click(function(){
            $(".company_content a").removeClass('color');
        });
        $(".department_Box .selectAll").click(function(){
            $(".department_Box a").removeClass('color');
        });
    });
