Javascript 用鼠标单击外部边界关闭弹出框,javascript,html,Javascript,Html,我制作了这个主页。具有带有登录字段的弹出框。当出现弹出窗口时，背景变暗。但是，如果用户单击框边界以外的任何位置，则弹出窗口应关闭。我已经创建了closeOverlay函数，当用户在键盘上点击esc时，它就可以工作，但是当用户在框的边界之外点击时，什么都不会发生。当用户点击escape或将鼠标移出框边界并单击时，如何使其在这两种情况下都能工作这是HTML代码 <head> <link rel="stylesheet" type="text/css" href="

试试这个

<div id="BackDIV" onclick="closeOverlay();"></div>

像这样？将事件侦听器添加到窗口，如果需要，请删除“确认”

var pop=document.getElementById'over'；window.addEventListener'click'函数{ 确认“关闭弹出窗口”？ pop.style.display=none:pop.style.display=block； }; 超过{最小宽度：80%；最小高度：100px；背景色：红色；}

这个问题与jQuery有什么关系？看起来你不是在用它。为什么有多个“closeOverlay”函数？为了回答你的问题：你能不能在BackDIV中添加一个eventListener？我将你的代码添加到HTML的顶部脚本部分，但它似乎没有任何作用：我不明白为什么这不起作用，你能在codepen或JSFIDLE中设置你的示例，这样我就可以看到它起作用了吗？当你单击下拉列表中的任何链接时，它仅通过esc退出，而不是用鼠标单击外部。这是JSFIDLE链接：很抱歉，图像不工作。当您浏览左上角的菜单时，单击3个链接中的任意一个。只有当我们在键盘上按esc键时，弹出窗口才会关闭，而不是在弹出区域外单击。编辑了我的答案，只是确认这在您的JSFIDLE中起作用。试一试，假设红色区域是我添加代码的弹出窗口，除了确认部分。但是在添加它之后，当我单击它们的链接时，我的弹出窗口一点也不显示我的坏消息，在您单击窗口关闭它们的那一刻，将其更改为window.addEventListener'click'，function{ifdocument.getElementById'BackDIV'{closeOverlay；}；如果他们开着，它就会关上。
