Question

我有jquery脚本，它会将clas添加到specfic li中。前三里它添加了类但是如果点击第4个到最后的li则它不适用。请帮助我：

html:

<ul class="sidebar-menu" id = "navigation">
    <li><a href="www.site.com/dashboard">Dashboard</a></li> 
    <li><a href="wwww.site.com/mycoupon">My Coupons</a></li> 
    <li><a href="www.site.com/member">View Profile</a></li>
    <li><a href="www.site.com/update">Update Profile</a></li>
</ul>

Jquery:

$(document).ready(function() {
    var  current_page = document.URL;

    if (current_page.match(/dashboard/)){
        $("ul#navigation li:eq(0)").addClass('selected sel');
    }

    else if (current_page.match(/mycoupon/)){
        $("ul#navigation li:eq(1)").addClass('selected sel');
    } 

    else if (current_page.match(/member/)){
        $("ul#navigation li:eq(2)").addClass('selected sel');
    }

    else if (current_page.match(/update/)){
        $("ul#navigation li:eq(3)").addClass('selected sel');
    } 

    else { // don't mark any nav links as selected
        $("ul#navigation li").removeClass('selected sel');
    }
});

您可以像这样使用

，而不是为每个菜单编写代码

$(document).ready(function() {
  var current_page = document.URL;
  $("#navigation li  a").filter(function() {
    return current_page.indexOf($(this).attr("href")) > -1
  }).closest("li").addClass("selected sel");
});
