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
});

我很惊讶没有人真正承认这一事件：
var button=document.getElementById（'button'）；button.addEventListener（'click'，函数（e）{e.target.style.backgroundColor=“绿色”；});button.addEventListener（'焦点'，函数（e）{e.target.style.backgroundColor=''；});<!DOCTYPE html><html><head><meta charset=“utf-8”></head><body><button id=“button”>单击</button></body></html>

外部点击插件！
用法：
$('.target-element').outsideClick(function(event){
//code that fires when user clicks outside the element
//event = the click event
//$(this) = the '.target-element' that is firing this function
}, '.excluded-element')
它的代码：
(function($) {
//when the user hits the escape key, it will trigger all outsideClick functions
$(document).on("keyup", function (e) {
if (e.which == 27) $('body').click(); //escape key
});
//The actual plugin
$.fn.outsideClick = function(callback, exclusions) {
var subject = this;
//test if exclusions have been set
var hasExclusions = typeof exclusions !== 'undefined';
//switches click event with touch event if on a touch device
var ClickOrTouchEvent = "ontouchend" in document ? "touchend" : "click";
$('body').on(ClickOrTouchEvent, function(event) {
//click target does not contain subject as a parent
var clickedOutside = !$(event.target).closest(subject).length;
//click target was on one of the excluded elements
var clickedExclusion = $(event.target).closest(exclusions).length;
var testSuccessful;
if (hasExclusions) {
testSuccessful = clickedOutside && !clickedExclusion;
} else {
testSuccessful = clickedOutside;
}
if(testSuccessful) {
callback.call(subject, event);
}
});
return this;
};
}(jQuery));

我在一些jQuery日历插件中找到了这个方法。
function ClickOutsideCheck(e)
{
var el = e.target;
var popup = $('.popup:visible')[0];
if (popup==undefined)
return true;
while (true){
if (el == popup ) {
return true;
} else if (el == document) {
$(".popup").hide();
return false;
} else {
el = $(el).parent()[0];
}
}
};
$(document).bind('mousedown.popup', ClickOutsideCheck);
功能：
$(function() {
$.fn.click_inout = function(clickin_handler, clickout_handler) {
var item = this;
var is_me = false;
item.click(function(event) {
clickin_handler(event);
is_me = true;
});
$(document).click(function(event) {
if (is_me) {
is_me = false;
} else {
clickout_handler(event);
}
});
return this;
}
});
用法：
this.input = $('<input>')
.click_inout(
function(event) { me.ShowTree(event); },
function() { me.Hide(); }
)
.appendTo(this.node);
功能非常简单：
ShowTree: function(event) {
this.data_span.show();
}
Hide: function() {
this.data_span.hide();
}
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();
});
$("body > div:not(#dvid)").click(function (e) {
//your code
});
