记住页面重新加载后的jQuery选项卡位置 [英] Remembering jQuery tab position after page reloads

问题描述

我有一个包含一些GridView的页面。我使用选项卡菜单将它们保存在选项卡中。有四个选项卡。

I have a page that contains some GridViews. I have kept them in tabs using tab-menu. There are four tabs.

我的问题是当页面重新加载时，选项卡会重置为第一个选项卡。

My problem is when the page reloads, the tab gets reset to the first tab.

HTML：

<div id="tabbed_box_1" class="tabbed_box">
    &nbsp; &nbsp;
    <div class="tabbed_area">
        <ul class="tabs">
            <li><a href="#" title="content_1" class="tab active">Bottom Banner</a></li>
            <li><a href="#" title="content_2" class="tab">Side Banner Bottom</a></li>
            <li><a href="#" title="content_3" class="tab">Side Banner Top</a></li>
            <li><a href="#" title="content_4" class="tab">Main Ad</a></li>
        </ul>
        <div id="content_1" class="content">
            <table width="500" border="0" align="center" cellpadding="0" cellspacing="2" class="border">
                <tr>
                    <td align="center">
                      //some gridview here
                    </td>
                </tr>
            </table>
        </div>
        //similarly three more gridviews

jQuery：

 $(document).ready(function () {

     // When a link is clicked
     $("a.tab").click(function () {

        // switch all tabs off
        $(".active").removeClass("active");

        // switch this tab on
        $(this).addClass("active");

        // slide all content up
        $(".content").slideUp();

        // slide this content up
        var content_show = $(this).attr("title");
        $("#" + content_show).slideDown();

    });
});

如果页面重新加载后如何制作当前点击的标签页呢？

How can I make the currently-clicked tab show even after page reloads?

推荐答案

简单的解决方案是使用 localStorage 保持选择：

The simple solution is to use localStorage to persist the selection :

 $(document).ready(function () {

        function activate(tab) {
           // switch all tabs off
            $(".active").removeClass("active");

            // switch this tab on
            tab.addClass("active");

            // slide all content up
            $(".content").slideUp();

            // slide this content up
            var content_show = tab.attr("title");
            $("#" + content_show).slideDown();
        }

        if (localStorage) { // let's not crash if some user has IE7
             var index = parseInt(localStorage['tab']||'0');
             activate($('a.tab').eq(index));
        }

        // When a link is clicked
        $("a.tab").click(function () {
            if (localStorage) localStorage['tab'] = $(this).closest('li').index();
            activate($(this));
        });

    });
