我有一些HTML菜单，当用户单击这些菜单的头部时，我会完全显示这些菜单。当用户在菜单区域外单击时，我希望隐藏这些元素。
jQuery是否可以实现这样的功能？
$("#menuscontainer").clickOutsideThisElement(function() {
// Hide the menus
});
当前回答
这是我的代码：
// Listen to every click
$('html').click(function(event) {
if ( $('#mypopupmenu').is(':visible') ) {
if (event.target.id != 'click_this_to_show_mypopupmenu') {
$('#mypopupmenu').hide();
}
}
});
// Listen to selector's clicks
$('#click_this_to_show_mypopupmenu').click(function() {
// If the menu is visible, and you clicked the selector again we need to hide
if ( $('#mypopupmenu').is(':visible') {
$('#mypopupmenu').hide();
return true;
}
// Else we need to show the popup menu
$('#mypopupmenu').show();
});

$（'html'）.click（function（）{//隐藏菜单（如果可见）});$（'#menucontainer'）.click（函数（事件）{event.stopPropagation（）；});<script src=“https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js“></script><html><button id=“#menucontainer”>确定</button></html>
可以为DOM元素设置tabindex。当用户在DOM元素外部单击时，这将触发一个模糊事件。
Demo
<div tabindex="1">
Focus me
</div>
document.querySelector("div").onblur = function(){
console.log('clicked outside')
}
document.querySelector("div").onfocus = function(){
console.log('clicked inside')
}
要做到这一点，最广泛的方法是选择网页上的所有内容，除了不希望检测到点击的元素，并在打开菜单时绑定点击事件。
然后，当菜单关闭时，移除绑定。
使用.stopPropagation可防止事件影响菜单容器的任何部分。
$("*").not($("#menuscontainer")).bind("click.OutsideMenus", function ()
{
// hide the menus
//then remove all of the handlers
$("*").unbind(".OutsideMenus");
});
$("#menuscontainer").bind("click.OutsideMenus", function (event)
{
event.stopPropagation();
});
$(document).click(function() {
$(".overlay-window").hide();
});
$(".overlay-window").click(function() {
return false;
});
如果单击文档，则隐藏给定元素，除非单击同一元素。
这里还有一个解决方案：

用法：
<div onClick="$('#menu').toggle();$('#menu').clickOutside(function() { $(this).hide(); $(this).clickOutside('disable'); });">Open / Close Menu</div>
<div id="menu" style="display: none; border: 1px solid #000000; background: #660000;">I am a menu, whoa is me.</div>
插件：
(function($) {
var clickOutsideElements = [];
var clickListener = false;
$.fn.clickOutside = function(options, ignoreFirstClick) {
var that = this;
if (ignoreFirstClick == null) ignoreFirstClick = true;
if (options != "disable") {
for (var i in clickOutsideElements) {
if (clickOutsideElements[i].element[0] == $(this)[0]) return this;
}
clickOutsideElements.push({ element : this, clickDetected : ignoreFirstClick, fnc : (typeof(options) != "function") ? function() {} : options });
$(this).on("click.clickOutside", function(event) {
for (var i in clickOutsideElements) {
if (clickOutsideElements[i].element[0] == $(this)[0]) {
clickOutsideElements[i].clickDetected = true;
}
}
});
if (!clickListener) {
if (options != null && typeof(options) == "function") {
$('html').click(function() {
for (var i in clickOutsideElements) {
if (!clickOutsideElements[i].clickDetected) {
clickOutsideElements[i].fnc.call(that);
}
if (clickOutsideElements[i] != null) clickOutsideElements[i].clickDetected = false;
}
});
clickListener = true;
}
}
}
else {
$(this).off("click.clickoutside");
for (var i = 0; i < clickOutsideElements.length; ++i) {
if (clickOutsideElements[i].element[0] == $(this)[0]) {
clickOutsideElements.splice(i, 1);
}
}
}
return this;
}
})(jQuery);
