我知道这是这个论坛上的一个常见问题，但我找不到具体的解决方案。

我要做的是根据复选框选择动态显示 HTML 链接。我无法弄清楚我做错了什么，此时代码似乎没有做任何事情。

下面是代码。

<!doctype html>
<html lang="en">

<head>
<meta charset="utf-8">
<meta name="description" content="GIT Courses" />

<title>GIT Courses</title>
<link href="courses3.css" rel="stylesheet" type="text/css">
<!-- We include the jQuery CSS, API, and UI from CDN in the Head -->
<!-- Most browsers have CDN fed libraries already in cache, as they are used very frequently  -->
<!-- This will speed up load times, reduce bandwidth use, and serve from closest geographical servers -->

您应该使用Attribute Starts With Selector [name^="value"]

$('input[name^="rescheck"]:checked')

你的代码应该是这样的： -

$('.resource').hide();
$('input[type="checkbox"]').click(function() {
    $("input[name^='rescheck']").each(function() {
        if ($(this).is(":checked"))
            $('div[resource-label="'+this.value+'"]').show();
        else
            $('div[resource-label="'+this.value+'"]').hide();
    });
});

您的 HTML 中有一些错误，我不知道这些是您实际脚本中的拼写错误还是在此处格式化时出现错误，但这一行需要整理：

<div  class="resource resource-label="Counseling Services">

请注意，这resource-label是当前元素类属性的一部分。

你可以为你的 jQuery 尝试一些类似的东西，让它对你来说更简单一些。 

$('#checkboxArray').on('click', 'input[type="checkbox"]', function(event)
{
    var resources = $('.myResources');

    // Hide all resources
    resources.children('div').hide();

    // Cycle through the checkboxes siblings
    $(this).siblings().each(function(index)
    {
        // If they are checked show the resource
        if ($(this).is(':checked') 
        {
            resources.find('div[resource-label="' + $(this).val() + '"]').show();
        }
    });
}

如果复选框与相关 div 的顺序相同，则使用元素索引作为参考。

$('input[name^="rescheck"]').click(function() { // if checkbox clicked
  var index = $(this).parent().index(); // gets parent index since nested in label
  $('.resource:eq(' + index + ')').toggle() // hide or show related div
});
