Question

在写这个问题之前，我一直在寻找解决方案，但到目前为止还找不到合适的东西。

我有三个内联的div容器，有两种状态，悬停和活动状态。在点击时，悬停的黑暗（不透明度0.5）变暗（0.8）。然后我创建了一个自定义状态，以便在单击时激活下拉div框时激活较暗状态保持打开状态。

所有三个div容器都有一个下拉框，点击后会激活。

我把所有这些都与以下几点分开，这对我来说是一个难点。

单击任何一个div容器时，所有div容器都变暗（不透明度为0.8），表示已激活，但是希望所选的一个变暗，而不是一次全部变暗。
可以通过单击页面上的任意位置来关闭下拉列表。点击十字架时设法关闭它。
当选择其中一个容器并且可以看到下拉列表时，任何容器都不应该是可点击的。我已经设法禁用指针操作但不是实际的点击，因为不希望你可以同时有多个下拉菜单的情况。即使已禁用指针操作，仍然可以单击，然后激活或停用自定义变暗的活动状态。

我尝试了许多JavaScript停用脚本，但没有一个适用于我。

代码如下：

JSFiddle：https://jsfiddle.net/0smLcfsx/14/

评论/更新：内联点击处理程序很糟糕，请尽量避免使用它们。（相关：onclick="" vs event handler）

您的bgbox点击功能非常相似。我已将它们归结为基于ID的通用函数（我还将ID从bgbox内部的div移动到bgbox本身，因为这是具有click处理程序的元素，可以＆＃ 39;看到div需要ID的原因。）

我还从弹出窗口（serv-desc-box1,2,3）中删除了ID，并将这些元素插入到与它们相关的服务盒中。这允许点击处理程序中的一些有趣的东西！我们应该创建一个能够处理自身的通用函数，而不是通过确定每个弹出窗口中确定单击哪个bg-box并调用自定义下拉函数的严格程序。通过这种方式，bgbox可以说＆＃34;打开容器内的弹出窗口＆＃34;而不是＆＃34;运行自定义函数来打开弹出窗口＆＃34;

对你的观点：

（1）这是由您的点击处理程序引起的： $（＆＃39; .cheader＆＃39;）。on（＆＃39; click＆＃39;，function（e）{ 您定义了三个（每个点击方案一个）。每当点击cheader时，都会运行这三个。我已将此功能合并为一个功能，希望更容易阅读。

（2）我添加了一个不可见的背景，当显示下拉列表时，该背景会弹出并具有z-index优先级。只要点击这个不可见的背景，它就会关闭下拉列表。

（3）与＃2相同。

Javascript

//Show/Hide Services Description Onclick

$(".invisible-background").on("click", function(e){
    $(".serv-desc-box").hide();
    $(".invisible-background").hide();
})

$(".bgbox").on("click", function(e){
    var id = $(this).attr("id");
    $("#"+id+"-desc").show();
    $(".invisible-background").show();
})

$(".cheader .bgbox").on("click", function(e){
    var id = $(this).find("div").attr("id");
    toggle_states(id);
});

function toggle_states(id_selector){
    var item = $(id_selector);
    item.find(".service-title").toggleClass('shade-a');
    item.find(".service-title h3").toggleClass('service-title-W');
    item.find(".service-title").toggleClass('disable');
    $(".service-title:not(#id_selector)").toggleClass('disable');
