从代码隐藏调用 jquery 函数，切换查询字符串

我有一个垂直菜单，它正在jquery上工作。HTML和Jquery如下：

.HTML：

<div id="menu">
            <ul class="navmenu">
                <li>
                    <div class="menutop menusingle">
                        <a id="A1" runat="server"  href="~/View.aspx?pg=aboutus" >About Us </a></div>
                </li>
                <li>
                    <div class="menutop">
                        <a href="#">Courses</a><div class="toggle">
                            +</div>
                    </div>
                    <ul class="submenu">
                        <li><a id="A6" runat="server"  href="~/View.aspx?pg=SoftwareIT">Software /IT</a></li>
                        <li><a id="A7" runat="server"  href="~/View.aspx?pg=Telecommunication">Telecommunication</a></li>
                        <li><a id="A8" runat="server"  href="~/View.aspx?pg=Hardware">Hardware & Networking</a></li>
                        <li><a id="A9" runat="server"  href="~/View.aspx?pg=Sales">Sales & Marketing</a></li>
                        <li><a id="A10" runat="server"  href="~/View.aspx?pg=BPO">BPO & Soft Skills</a></li>
                    </ul>
                </li>
                <li>
                    <div class="menutop">
                        <a href="#">Services</a><div class="toggle">
                            +</div>
                    </div>
                    <ul class="submenu">
                        <li><a id="A2" runat="server"  href="~/View.aspx?pg=IndividualTraining">Individual Training </a></li>
                        <li><a id="A3" runat="server"  href="~/View.aspx?pg=OncampusTraining ">On Campus Training </a></li>
                        <li><a id="A4" runat="server"  href="~/View.aspx?pg=CorporateTraining">Corporate Training </a></li>
                        <li><a id="A5" runat="server"  href="~/View.aspx?pg=Placement">Placement </a></li>
                    </ul>
                </li>
                <li>
                    <div class="menutop">
                        <a href="#">Trainings</a><div class="toggle">
                            +</div>
                    </div>
                    <ul class="submenu">
                        <li><a id="A11" runat="server"  href="~/View.aspx?pg=FastTrack">FastTrack Training</a></li>
                        <li><a id="A12" runat="server"  href="~/View.aspx?pg=Summer">Summer/Industrial</a></li>
                        <li><a id="A13" runat="server"  href="~/View.aspx?pg=Weekend">Weekend Training</a></li>
                    </ul>
                </li>
            </ul>
        </div>

单击 + 号后，打开子菜单的抽屉。这是手动非常精细的。现在我想根据要求自动化它。我们已经切换了培训，课程和服务，因此如果当前URL是服务，则服务菜单将自动打开。因为我们也有顶部导航和页脚导航。以上是左侧导航。

Jquery相同：

<script type="text/javascript">
    $(document).ready(function() {
        $('.toggle:not(.toggle-open)').addClass('toggle-closed').parents('li').children('ul').hide();
        if ($.browser.msie) {
            $('#menu ul.navmenu li:last-child .menutop').css('border-bottom', '1px solid #CCC');
        }
        $('.toggle').click(function() {
            if ($(this).hasClass('toggle-open')) {
                $(this).removeClass('toggle-open').addClass('toggle-closed').empty('').append('+').parents('li').children('ul').slideUp(250);
                $(this).parent('.menutop').removeClass('menutop-open').addClass('menutop-closed');
            } else {
                $(this).parent('.menutop').removeClass('menutop-closed').addClass('menutop-open');
                $(this).removeClass('toggle-closed').addClass('toggle-open').empty('').append('&ndash;').parents('li').children('ul').slideDown(250);
            }
        });
    })
</script>

所以我需要一种方法来根据查询字符串从 cs $('.toggle').click(function() 调用。
