javascript - 编码不当的 JQuery : naming dependancies

Question

我的页面上有几个带有此标记的选项卡

<div id="holiday-details-nav">
                <ul>
                    <li><a class="holidaydetails-description" title="Overview" href="#tab-holidaydetails-overview">Overview</a></li>
                    <li><a class="holidaydetails-included" title="Rooms" href="#tab-holidaydetails-rooms">Rooms</a></li>
                    <li><a class="holidaydetails-itinerary" title="Rates" href="#tab-holidaydetails-rates">Rates</a></li>  
                    <li><a class="holidaydetails-accommodation" title="Information" href="#tab-holidaydetails-information">Information</a></li>                         
                    <li><a class="holidaydetails-reviews" title="Reviews" href="#tab-holidaydetails-reviews">Reviews</a></li>
                </ul>
            </div>

这些选项卡中内容的隐藏和显示由一些由此开始的 JQuery 代码控制

$(document).ready(function () {
    // Hide all tabs apart from the overview
    $('#holiday-details-tabs div:#tab-holidaydetails-rooms').hide();
    $('#holiday-details-tabs div:#tab-holidaydetails-rates').hide();
    $('#holiday-details-tabs div:#tab-holidaydetails-information').hide();
    $('#holiday-details-tabs div:#tab-holidaydetails-reviews').hide();
    ...

问题是，如果我添加、删除或重命名选项卡(就像我刚刚所做的那样)，那么我必须更改所有这些代码。我想要的是添加、重命名或删除任意数量的选项卡，但不必修改此 JQuery 代码。

我并不是真的在寻找有人为我编写解决方案，而是想开始讨论可用于避免这种命名依赖的工具、技术等。

编辑

当单击选项卡时，我也有一点丑陋。

$('#holiday-details-nav ul li a').click(function () {
    // Remove active class from all links
    $('#holiday-details-nav ul li').removeClass('active');
    //Set clicked link class to active
    $(this).parent().addClass('active');
    // Set variable currentTab to value of href attribute of clicked link
    var currentTab = $(this).attr('href');
    // Hide all tabs
    $('#holidaydetails-description-imagecontainer').hide();
    $('#holiday-details-tabs div:#tab-holidaydetails-overview').hide();
    $('#holiday-details-tabs div:#tab-holidaydetails-rooms').hide();
    $('#holiday-details-tabs div:#tab-holidaydetails-rates').hide();
    $('#holiday-details-tabs div:#tab-holidaydetails-information').hide();
    $('#holiday-details-tabs div:#tab-holidaydetails-reviews').hide();

    $('#holiday-details-bottom').show();
    $('#holiday-details-left-booknow').show();

    // Show div with id equal to variable currentTab
    $(currentTab).show();

    $('#holidaydetails-description-imagecontainer').show();

    return false;
});

谢谢

您可以为每个li 除了概述分配一个通用 CSS类，例如tab，然后使用 jQuery 类选择器来隐藏它们。例如:

<div id="holiday-details-nav">
  <ul>
    <li><a class="holidaydetails-description" title="Overview" href="#tab-holidaydetails-overview">Overview</a></li>
    <li><a class="tab holidaydetails-included" title="Rooms" href="#tab-holidaydetails-rooms">Rooms</a></li>
    <li><a class="tab holidaydetails-itinerary" title="Rates" href="#tab-holidaydetails-rates">Rates</a></li>  
    <li><a class="tab holidaydetails-accommodation" title="Information" href="#tab-holidaydetails-information">Information</a></li>                         
    <li><a class="tab holidaydetails-reviews" title="Reviews" href="#tab-holidaydetails-reviews">Reviews</a></li>
  </ul>
</div>

然后，隐藏除概述之外的所有选项卡:

$("holiday-details-nav .tab").hide();

或者相反，即将特定的类添加到概述中，并隐藏所有其他选项卡:

<div id="holiday-details-nav">
  <ul>
    <li><a class="overview holidaydetails-description" title="Overview" href="#tab-holidaydetails-overview">Overview</a></li>
    <li><a class="holidaydetails-included" title="Rooms" href="#tab-holidaydetails-rooms">Rooms</a></li>
    <li><a class="holidaydetails-itinerary" title="Rates" href="#tab-holidaydetails-rates">Rates</a></li>  
    <li><a class="holidaydetails-accommodation" title="Information" href="#tab-holidaydetails-information">Information</a></li>                         
    <li><a class="holidaydetails-reviews" title="Reviews" href="#tab-holidaydetails-reviews">Reviews</a></li>
  </ul>
</div>

然后，要隐藏，请选择所有选项卡，并使用 .not() 排除概览:

$("#holiday-details-nav a").not(".overview").hide();
