如果用户在下拉菜单之外单击，如何关闭下拉菜单？

Question

I am making user dropdown when we click on the picture we get a dropdown or a card.当我们点击图片时，我正在制作用户下拉菜单，我们会得到一个下拉菜单或一张卡片。 I want to close it when user click outside of dropdown.当用户在下拉菜单之外单击时，我想关闭它。 The code of closing will be in JavaScript.关闭代码将使用 JavaScript。 Please solve this problem.请解决这个问题。 I think there will be a remove function in JavaScript which will remove the dropdown after clicking on it.我认为 JavaScript 中会有一个删除功能，它会在点击下拉菜单后删除它。

Bind click on document and remove opened class on click of document.绑定单击文档并在单击文档时删除opened类。
Usee.stopPropagation() so that event does not propagate on document which event is invoked on click of the .menubtn使用e.stopPropagation()以便事件不会在单击.menubtn调用哪个事件的document上传播

 $('.menubtn').on('click', function(e) { e.stopPropagation(); $('.navmenu').toggleClass('opened'); }); $(document).on('click', function() { $('.navmenu').removeClass('opened'); });

 body { margin: 0; background: tomato; font-family: 'Open Sans', sans-serif; } .menubtn { cursor: pointer; width: 40px; height: 20px; right: 10px; top: 10px; position: absolute; } .userimg { border-radius: 50%; height: 35px; width: 35px; } .navmenu { width: 150px; border-radius: 10px; margin-top: 30px; background: #fff; position: absolute; right: 18px; top: 25px; box-shadow: 0 0 10px 2px rgba(0, 0, 0, 0.15); z-index: 10; visibility: hidden; opacity: 0; -webkit-transition: all 300ms ease; transition: all 300ms ease; } .navmenu.opened { visibility: visible; opacity: 1; } .navmenu::before { content: ''; position: absolute; top: -5px; right: 7px; width: 15px; height: 15px; background: #fff; -webkit-transform: rotate(45deg); transform: rotate(45deg); } .navmenu ul { list-style: none; margin: 0; padding: 0; } .navmenu ul.text-list { text-align: left; font-weight: 100; width: 100%; margin: auto; padding-top: 10px; padding-bottom: 10px; } .navmenu ul.text-list li a { text-decoration: none; padding-left: 20px; padding-top: 5px; color: #343434; font-weight: 600; display: block; line-height: 27px; -webkit-transition: all 200ms ease; transition: all 200ms ease; } .navmenu ul.text-list li a:hover { color: tomato; }
