在 Bootstrap 3 中单击导航栏元素外部时如何关闭打开的折叠导航栏? [英] How to close an open collapsed navbar when clicking outside of the navbar element in Bootstrap 3?

问题描述

如何在导航栏元素外部单击时关闭打开的折叠导航栏?目前，打开或关闭它的唯一方法是点击 navbar-toggle 按钮.

How can I close an open collapsed navbar on clicking outside of the navbar element? Currently, the only way to open or close it is by clicking on the navbar-toggle button.

查看这里的示例和代码:

到目前为止，我已经尝试了以下似乎不起作用的方法:

So far, I have tried the following which doesn't seem to work:

jQuery(document).click(function() {

});

jQuery('.navbar').click(function(event) {
    jQuery(".navbar-collapse").collapse('hide');
    event.stopPropagation();
});

推荐答案

看看:

$(document).ready(function () {
    $(document).click(function (event) {
        var clickover = $(event.target);
        var _opened = $(".navbar-collapse").hasClass("navbar-collapse in");
        if (_opened === true && !clickover.hasClass("navbar-toggle")) {
            $("button.navbar-toggle").click();
        }
    });
});

它是 这个答案，缺少动画，也稍微复杂一点.

Its a modified version of this answer, which lacks the animation and is also a tiny bit more complicated.

我知道，调用 click() 不是很优雅，但是 collapse('hide') 对我也不起作用，我认为动画比几乎添加和删除类要好一些.

I know, invoking the click() isn't very elegant, but collapse('hide') did not work for me either, and i think the animation is a bit nicer than adding and removing the classes hardly.
