在 Bootstrap 中动态添加/删除选项卡 - 使创建的选

Add / Remove Tabs Dynamically in Bootstrap - Make created tab active(在 Bootstrap 中动态添加/删除选项卡 - 使创建的选项卡处于活动状态)

问题描述

这是动态添加/删除引导选项卡的代码段.一切正常，但我希望新创建的选项卡处于活动状态并处于焦点，而不是用于动态添加选项卡的选项卡.

Here is the snippet to dynamically add / remove bootstrap tabs. Everything works fine, but I would like newly created tab to be active and in focus rather than the tab used to dynamically add a tab.

这是有问题的代码:

HTML:

<div class="container">
    <ul class="nav nav-tabs">
        <li class="active"><a href="#contact_01" data-toggle="tab">Joe Smith</a><span>x</span></li>
        <li><a href="#contact_02" data-toggle="tab">Molly Lewis</a><span>x</span> </li>
        <li><a href="#" class="add-contact" data-toggle="tab">+ Add Contact</a></li>
    </ul>
    <div class="tab-content">
        <div class="tab-pane active" id="contact_01">Contact Form: Joe Smith</div>
        <div class="tab-pane" id="contact_02">Contact Form: Molly Lewis</div>
    </div>
</div>

JS:

$(".nav-tabs").on("click", "a", function(e){
      e.preventDefault();
      $(this).tab('show');
    })
    .on("click", "span", function () {
        var anchor = $(this).siblings('a');
        $(anchor.attr('href')).remove();
        $(this).parent().remove();
        $(".nav-tabs li").children('a').first().click();
    });

    $('.add-contact').click(function(e) {
        e.preventDefault();
        var id = $(".nav-tabs").children().length; //think about it ;)
        $(this).closest('li').before('<li><a href="#contact_'+id+'">New Tab</a><span>x</span></li>');         
        $('.tab-content').append('<div class="tab-pane" id="contact_'+id+'">Contact Form: New Contact '+id+'</div>');
});

CSS:

@import url('http://getbootstrap.com/2.3.2/assets/css/bootstrap.css');

.container {
    margin-top: 10px;
}

.nav-tabs > li {
    position:relative;    
}

.nav-tabs > li > a {
    display:inline-block;
}

.nav-tabs > li > span {
    display:none;
    cursor:pointer;
    position:absolute;
    right: 6px;
    top: 8px;
    color: red;
}

.nav-tabs > li:hover > span {
    display: inline-block;
}

推荐答案

这里有一个解决方案:

1. tab('show') 仍然在添加联系人"时被调用.导航链接被点击.即使调用了显示选项卡功能，也不会显示选项卡内容，因为它没有链接到它的现有内容.我所做的是添加一个条件来停止激活该选项卡.

1. The tab('show') is still being called when the "Add Contact" navlink is clicked. Even though the show tab function is called, no tab content is being displayed because it has no existing contents linked to it. What I did is to add a condition to stop activating that tab.

$(".nav-tabs").on("click", "a", function (e) {
     e.preventDefault();
     if (!$(this).hasClass('add-contact')) {
         $(this).tab('show');
     }
})

<li><a href="#" class="add-contact">+ Add Contact</a></li>

$('.add-contact').click(function (e) {
     e.preventDefault();
     var id = $(".nav-tabs").children().length; //think about it ;)
     var tabId = 'contact_' + id;
     $(this).closest('li').before('<li><a href="#contact_' + id + '">New Tab</a> <span>x</span></li>');
     $('.tab-content').append('<div class="tab-pane" id="' + tabId + '">Contact Form: New Contact ' + id + '</div>');

     // add this
     $('.nav-tabs li:nth-child(' + id + ') a').click();
});
