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
});

标记为接受答案的答案没有考虑到元素上可以有覆盖，如对话框、弹出窗口、日期选择器等。单击这些按钮不应隐藏元素。

我制作了自己的版本，确实考虑到了这一点。它是作为KnockoutJS绑定创建的，但它可以很容易地仅转换为jQuery。

它通过第一次查询所有具有z索引或绝对位置的可见元素来工作。然后，如果在外部单击，它会根据我想要隐藏的元素来测试这些元素。如果是命中，我会计算一个新的边界矩形，该矩形考虑到覆盖边界。

ko.bindingHandlers.clickedIn = (function () {
    function getBounds(element) {
        var pos = element.offset();
        return {
            x: pos.left,
            x2: pos.left + element.outerWidth(),
            y: pos.top,
            y2: pos.top + element.outerHeight()
        };
    }

    function hitTest(o, l) {
        function getOffset(o) {
            for (var r = { l: o.offsetLeft, t: o.offsetTop, r: o.offsetWidth, b: o.offsetHeight };
                o = o.offsetParent; r.l += o.offsetLeft, r.t += o.offsetTop);
            return r.r += r.l, r.b += r.t, r;
        }

        for (var b, s, r = [], a = getOffset(o), j = isNaN(l.length), i = (j ? l = [l] : l).length; i;
            b = getOffset(l[--i]), (a.l == b.l || (a.l > b.l ? a.l <= b.r : b.l <= a.r))
                && (a.t == b.t || (a.t > b.t ? a.t <= b.b : b.t <= a.b)) && (r[r.length] = l[i]));
        return j ? !!r.length : r;
    }

    return {
        init: function (element, valueAccessor) {
            var target = valueAccessor();
            $(document).click(function (e) {
                if (element._clickedInElementShowing === false && target()) {
                    var $element = $(element);
                    var bounds = getBounds($element);

                    var possibleOverlays = $("[style*=z-index],[style*=absolute]").not(":hidden");
                    $.each(possibleOverlays, function () {
                        if (hitTest(element, this)) {
                            var b = getBounds($(this));
                            bounds.x = Math.min(bounds.x, b.x);
                            bounds.x2 = Math.max(bounds.x2, b.x2);
                            bounds.y = Math.min(bounds.y, b.y);
                            bounds.y2 = Math.max(bounds.y2, b.y2);
                        }
                    });

                    if (e.clientX < bounds.x || e.clientX > bounds.x2 ||
                        e.clientY < bounds.y || e.clientY > bounds.y2) {

                        target(false);
                    }
                }
                element._clickedInElementShowing = false;
            });

            $(element).click(function (e) {
                e.stopPropagation();
            });
        },
        update: function (element, valueAccessor) {
            var showing = ko.utils.unwrapObservable(valueAccessor());
            if (showing) {
                element._clickedInElementShowing = true;
            }
        }
    };
})();

试试这个：

$('html').click(function(e) {
  if($(e.target).parents('#menuscontainer').length == 0) {
    $('#menuscontainer').hide();
  }
});

但请注意，如果单击事件无法到达html标记，则这将无法工作。（可能其他元素已停止传播（））。

我只是想让@Pistos的回答更加明显，因为它隐藏在评论中。

这个解决方案非常适合我

var elementToToggle = $('.some-element');
$(document).click( function(event) {
  if( $(event.target).closest(elementToToggle).length === 0 ) {
    elementToToggle.hide();
  }
});

在CoffeeScript中：

elementToToggle = $('.some-element')
$(document).click (event) ->
  if $(event.target).closest(elementToToggle).length == 0
    elementToToggle.hide()

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));
