Bootstrap 3:在页面刷新时保持选中的选项卡

Question

我试图通过Bootstrap 3在刷新时保持选定的选项卡处于活动状态.尝试并检查了一些问题已经在这里被问过,但没有为我工作.不知道我哪里错了.这是我的代码

HTML

<!-- tabs link -->
<ul class="nav nav-tabs" id="rowTab">
    <li class="active"><a href="#personal-info" data-toggle="tab">Personal Information</a></li>
    <li><a href="#Employment-info" data-toggle="tab">Employment Information</a></li>
    <li><a href="#career-path" data-toggle="tab">Career Path</a></li>
    <li><a href="#warnings" data-toggle="tab">Warning</a></li>
</ul>
<!-- end: tabs link -->

<div class="tab-content">
    <div class="tab-pane active" id="personal-info">
        tab data here...
    </div>

    <div class="tab-pane" id="Employment-info">
        tab data here...
    </div>

    <div class="tab-pane" id="career-path">
        tab data here...
    </div>

    <div class="tab-pane" id="warnings">
        tab data here...
    </div>
</div>

Javascript:

// tab
$('#rowTab a:first').tab('show');

//for bootstrap 3 use 'shown.bs.tab' instead of 'shown' in the next line
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
//save the latest tab; use cookies if you like 'em better:
localStorage.setItem('selectedTab', $(e.target).attr('id'));
});

//go to the latest tab, if it exists:
var selectedTab = localStorage.getItem('selectedTab');
if (selectedTab) {
  $('#'+selectedTab).tab('show');
}

Answer 1

我更喜欢将选定的选项卡存储在窗口的哈希值中.这样也可以向同事发送链接,而不是看到"相同"的页面.诀窍是在选择另一个选项卡时更改位置的哈希值.如果您已在页面中使用#,则可能必须拆分散列标记.在我的应用程序中,我使用":"作为哈希值分隔符.

<ul class="nav nav-tabs" id="myTab">
  <li class="active"><a href="#home">Home</a></li>
  <li><a href="#profile">Profile</a></li>
  <li><a href="#messages">Messages</a></li>
  <li><a href="#settings">Settings</a></li>
</ul>

<div class="tab-content">
  <div class="tab-pane active" id="home">home</div>
  <div class="tab-pane" id="profile">profile</div>
  <div class="tab-pane" id="messages">messages</div>
  <div class="tab-pane" id="settings">settings</div>
</div>

JavaScript,必须在上面的<script>...</script>部分之后嵌入.

$('#myTab a').click(function(e) {
  e.preventDefault();
  $(this).tab('show');
});

// store the currently selected tab in the hash value
$("ul.nav-tabs > li > a").on("shown.bs.tab", function(e) {
  var id = $(e.target).attr("href").substr(1);
  window.location.hash = id;
});

// on load of the page: switch to the currently selected tab
var hash = window.location.hash;
$('#myTab a[href="' + hash + '"]').tab('show');

Answer 2

这是我尝试过的最好的一个:

$(document).ready(function() {
    if (location.hash) {
        $("a[href='" + location.hash + "']").tab("show");
    }
    $(document.body).on("click", "a[data-toggle='tab']", function(event) {
        location.hash = this.getAttribute("href");
    });
});
$(window).on("popstate", function() {
    var anchor = location.hash || $("a[data-toggle='tab']").first().attr("href");
    $("a[href='" + anchor + "']").tab("show");
});

Answer 3

其他人之间的混合回答:

• 没有跳转点击
• 保存位置哈希
• 保存在localStorage上(例如:表单提交)

• 只需复制并粘贴;)

  if (location.hash) {
    $('a[href=\'' + location.hash + '\']').tab('show');
  }
  var activeTab = localStorage.getItem('activeTab');
  if (activeTab) {
    $('a[href="' + activeTab + '"]').tab('show');
  }
  
  $('body').on('click', 'a[data-toggle=\'tab\']', function (e) {
    e.preventDefault()
    var tab_name = this.getAttribute('href')
    if (history.pushState) {
      history.pushState(null, null, tab_name)
    }
    else {
      location.hash = tab_name
    }
    localStorage.setItem('activeTab', tab_name)
  
    $(this).tab('show');
    return false;
  });
  $(window).on('popstate', function () {
    var anchor = location.hash ||
      $('a[data-toggle=\'tab\']').first().attr('href');
    $('a[href=\'' + anchor + '\']').tab('show');
  });
  

Answer 4

哈维的代码几乎全部工作.但是当导航到另一个页面,提交表单,然后被重定向到带有我的选项卡的页面时,根本没有加载保存的选项卡.

localStorage救援(稍微改变了Nguyen的代码):

$('a[data-toggle="tab"]').click(function (e) {
    e.preventDefault();
    $(this).tab('show');
});

$('a[data-toggle="tab"]').on("shown.bs.tab", function (e) {
    var id = $(e.target).attr("href");
    localStorage.setItem('selectedTab', id)
});

var selectedTab = localStorage.getItem('selectedTab');
if (selectedTab != null) {
    $('a[data-toggle="tab"][href="' + selectedTab + '"]').tab('show');
}

Answer 5

这个使用HTML5 localStorage来存储活动标签

$('a[data-toggle="tab"]').on('shown.bs.tab', function(e) {
    localStorage.setItem('activeTab', $(e.target).attr('href'));
});
var activeTab = localStorage.getItem('activeTab');
if (activeTab) {
   $('#navtab-container a[href="' + activeTab + '"]').tab('show');
}

Answer 6

根据Xavi Martínez和koppor提供的答案，我想出了一个使用 url 哈希或 localStorage 的解决方案，具体取决于后者的可用性：

function rememberTabSelection(tabPaneSelector, useHash) {
    var key = 'selectedTabFor' + tabPaneSelector;
    if(get(key)) 
        $(tabPaneSelector).find('a[href=' + get(key) + ']').tab('show');

    $(tabPaneSelector).on("click", 'a[data-toggle]', function(event) {
        set(key, this.getAttribute('href'));
    }); 

    function get(key) {
        return useHash ? location.hash: localStorage.getItem(key);
    }

    function set(key, value){
        if(useHash)
            location.hash = value;
        else
            localStorage.setItem(key, value);
    }
}

用法：

$(document).ready(function () {
    rememberTabSelection('#rowTab', !localStorage);
    // Do Work...
});

它跟不上后退按钮，就像Xavi Martínez的解决方案一样。

Answer 7

我的代码，它对我有用，我使用localStorageHTML5

$('#tabHistory  a').click(function(e) {
  e.preventDefault();
  $(this).tab('show');
});
$("ul.nav-tabs#tabHistory > li > a").on("shown.bs.tab", function(e) {
  var id = $(e.target).attr("href");
  localStorage.setItem('selectedTab', id)
});
var selectedTab = localStorage.getItem('selectedTab');
$('#tabHistory a[href="' + selectedTab + '"]').tab('show');

Answer 8

我尝试了这个并且它有效：

    jQuery(document).ready(function() {
        jQuery('a[data-toggle="pill"]').on('show.bs.tab', function(e) {
            localStorage.setItem('activeTab', jQuery(e.target).attr('href'));
        });

        // Here, save the index to which the tab corresponds. You can see it 
        // in the chrome dev tool.
        var activeTab = localStorage.getItem('activeTab');

        // In the console you will be shown the tab where you made the last 
        // click and the save to "activeTab". I leave the console for you to 
        // see. And when you refresh the browser, the last one where you 
        // clicked will be active.
        console.log(activeTab);

        if (activeTab) {
           jQuery('a[href="' + activeTab + '"]').tab('show');
        }
    });

我希望它能帮助别人。

嗯，这已经是 2018 年了，但我认为迟到总比没有好（就像电视节目中的标题一样），哈哈。下面是我在论文中创建的 jQuery 代码。

<script type="text/javascript">
$(document).ready(function(){
    $('a[data-toggle="tab"]').on('show.affectedDiv.tab', function(e) {
        localStorage.setItem('activeTab', $(e.target).attr('href'));
    });
    var activeTab = localStorage.getItem('activeTab');
    if(activeTab){
        $('#myTab a[href="' + activeTab + '"]').tab('show');
    }
});
</script>

这是引导程序选项卡的代码：

<div class="affectedDiv">
    <ul class="nav nav-tabs" id="myTab">
        <li class="active"><a data-toggle="tab" href="#sectionA">Section A</a></li>
        <li><a data-toggle="tab" href="#sectionB">Section B</a></li>
        <li><a data-toggle="tab" href="#sectionC">Section C</a></li>
    </ul>
    <div class="tab-content">
        <div id="sectionA" class="tab-pane fade in active">
            <h3>Section A</h3>
            <p>Aliquip placeat salvia cillum iphone. Seitan aliquip quis cardigan american apparel, butcher voluptate nisi qui. Raw denim you probably haven't heard of them jean shorts Austin. Nesciunt tofu stumptown aliqua, retro synth master cleanse. Mustache cliche tempor, williamsburg carles vegan helvetica. Reprehenderit butcher retro keffiyeh dreamcatcher synth.</p>
        </div>
        <div id="sectionB" class="tab-pane fade">
            <h3>Section B</h3>
            <p>Vestibulum nec erat eu nulla rhoncus fringilla ut non neque. Vivamus nibh urna, ornare id gravida ut, mollis a magna. Aliquam porttitor condimentum nisi, eu viverra ipsum porta ut. Nam hendrerit bibendum turpis, sed molestie mi fermentum id. Aenean volutpat velit sem. Sed consequat ante in rutrum convallis. Nunc facilisis leo at faucibus adipiscing.</p>
        </div>
        <div id="sectionC" class="tab-pane fade">
            <h3>Section C</h3>
            <p>Vestibulum nec erat eu nulla rhoncus fringilla ut non neque. Vivamus nibh urna, ornare id gravida ut, mollis a magna. Aliquam porttitor condimentum nisi, eu viverra ipsum porta ut. Nam hendrerit bibendum turpis, sed molestie mi fermentum id. Aenean volutpat velit sem. Sed consequat ante in rutrum convallis. Nunc facilisis leo at faucibus adipiscing.</p>
        </div>
    </div>
</div>

不要忘记调用引导程序和其他基本的东西 

以下是为您提供的快速代码：

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

现在让我们来解释一下：

上面示例中的 jQuery 代码仅在使用 jQuery .attr() 方法显示新选项卡时获取元素的 href 属性值，并通过 HTML5 localStorage 对象将其本地保存在用户浏览器中。稍后，当用户刷新页面时，它会检索此数据并通过 .tab('show') 方法激活相关选项卡。
