这对我来说很好。我不是专家。

$(document).click(function(event) {
  var $target = $(event.target);
  if(!$target.closest('#hamburger, a').length &&
  $('#hamburger, a').is(":visible")) {
    $('nav').slideToggle();
  }
});

Use:

var go = false;
$(document).click(function(){
    if(go){
        $('#divID').hide();
        go = false;
    }
})

$("#divID").mouseover(function(){
    go = false;
});

$("#divID").mouseout(function (){
    go = true;
});

$("btnID").click( function(){
    if($("#divID:visible").length==1)
        $("#divID").hide(); // Toggle
    $("#divID").show();
});

这是一个经典的例子，对HTML进行调整将是更好的解决方案。为什么不在不包含菜单项的元素上设置单击？那么您不需要添加传播。

$('.header, .footer, .main-content').click(function() {
//Hide the menus if visible
});

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));

对于那些希望将一个简短的解决方案集成到JS代码中的人来说——一个没有JQuery的小型库：

用法：

// demo code
var htmlElem = document.getElementById('my-element')
function doSomething(){ console.log('outside click') }

// use the lib
var removeListener = new elemOutsideClickListener(htmlElem, doSomething);

// deregister on your wished event
$scope.$on('$destroy', removeListener);

下面是库：

function elemOutsideClickListener (element, outsideClickFunc, insideClickFunc) {
   function onClickOutside (e) {
      var targetEl = e.target; // clicked element
      do {
         // click inside
         if (targetEl === element) {
            if (insideClickFunc) insideClickFunc();
            return;

         // Go up the DOM
         } else {
            targetEl = targetEl.parentNode;
         }
      } while (targetEl);

      // click outside
      if (!targetEl && outsideClickFunc) outsideClickFunc();
   }

   window.addEventListener('click', onClickOutside);

   return function () {
      window.removeEventListener('click', onClickOutside);
   };
}

我从这里获取代码并将其放在函数中：https://www.w3docs.com/snippets/javascript/how-to-detect-a-click-outside-an-element.html

$("body > div:not(#dvid)").click(function (e) {
    //your code
});
