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
});

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));

$("#menuscontainer").click(function() {
$(this).focus();
});
$("#menuscontainer").blur(function(){
$(this).hide();
});
对我来说很好。
尝试以下代码：
if ($(event.target).parents().index($('#searchFormEdit')) == -1 &&
$(event.target).parents().index($('.DynarchCalendar-topCont')) == -1 &&
(_x < os.left || _x > (os.left + 570) || _y < os.top || _y > (os.top + 155)) &&
isShowEditForm) {
setVisibleEditForm(false);
}
这是一个更通用的解决方案，它允许监视多个元素，并动态地从队列中添加和删除元素。
它保存一个全局队列（autoCloseQueue）——一个对象容器，用于在外部单击时应关闭的元素。
每个队列对象键都应该是DOM元素id，值应该是一个具有2个回调函数的对象：
{onPress: someCallbackFunction, onOutsidePress: anotherCallbackFunction}
将其放入文档就绪回调中：
window.autoCloseQueue = {}
$(document).click(function(event) {
for (id in autoCloseQueue){
var element = autoCloseQueue[id];
if ( ($(e.target).parents('#' + id).length) > 0) { // This is a click on the element (or its child element)
console.log('This is a click on an element (or its child element) with id: ' + id);
if (typeof element.onPress == 'function') element.onPress(event, id);
} else { //This is a click outside the element
console.log('This is a click outside the element with id: ' + id);
if (typeof element.onOutsidePress == 'function') element.onOutsidePress(event, id); //call the outside callback
delete autoCloseQueue[id]; //remove the element from the queue
}
}
});
然后，当创建id为“menuscontainer”的DOM元素时，只需将此对象添加到队列：
window.autoCloseQueue['menuscontainer'] = {onOutsidePress: clickOutsideThisElement}
$（'html'）.click（function（）{//隐藏菜单（如果可见）});$（'#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>
如果您正在为IE和FF 3.*编写脚本，并且您只想知道单击是否发生在某个框区域内，您也可以使用以下内容：
this.outsideElementClick=函数（objEvent，objElement）{var objCurrentElement=objEvent.target | | objEvent.srcElement；var blnSideX=false；var blnSideY=false；如果（objCurrentElement.getBoundingClientRect（）.left>=objElement.getBoundingClientRect（）.left&&objCurrentElement.getBoundingClientRectblnSideX=真；如果（objCurrentElement.getBoundingClientRect（）.top>=objElement.getBoundingClientRect（）.ttop&&objCurrentElement.getBoundingClientRectblnSideY=真；如果（blnSideX&&blnSideY）return false；其他的返回true；}
