如何通过页面上任何地方（否则）点击关闭Twitter Bootstrap popover？ [英] How can I close a Twitter Bootstrap popover with a click from anywhere (else) on the page?

问题描述

我目前正在使用Twitter Bootstrap的popovers，就像这样发起：

I'm currently using popovers with Twitter Bootstrap, initiated like this:

$('.popup-marker').popover({
        html: true,
        trigger: 'manual'
    }).click(function(e) {
        $(this).popover('toggle');
        e.preventDefault();
    });

如你所见，它们是手动触发的，然后点击.popup-marker（这是带有背景图像的div）切换弹出窗口。这很好用，但我也希望能够通过点击页面上任何其他位置来关闭popover（但不能在popover本身！）。

As you can see, they're triggered manually, and clicking on .popup-marker (which is a div with a background image) toggles a popover. This works great, but I'd like to also be able to close the popover with a click anywhere else on the page (but not on the popover itself!).

我尝试了一些不同的东西，包括以下内容，但没有显示结果：

I've tried a few different things, including the following, but with no results to show for it:

$('body').click(function(e) {
    $('.popup-marker').popover('hide');
});

如何通过点击页面上的任何其他位置来关闭popover，但不能点击弹出窗口本身？

推荐答案

假设任何时候只能看到一个弹出框，你可以使用当一个弹出窗口可见时标记的一组标志，然后才隐藏它们。

Presuming that only one popover can be visible at any time, you can use a set of flags to mark when there's a popover visible, and only then hide them.

如果在文档正文上设置事件监听器，则单击时会触发它标有弹出标记的元素。因此，您必须在事件对象上调用 stopPropagation（）。单击popover本身时应用相同的技巧。

If you set the event listener on the document body, it will trigger when you click the element marked with 'popup-marker'. So you'll have to call stopPropagation() on the event object. And apply the same trick when clicking on the popover itself.

下面是一个可以执行此操作的JavaScript代码。它使用jQuery> = 1.7

Below is a working JavaScript code that does this. It uses jQuery >= 1.7

jQuery(function() {
    var isVisible = false;

    var hideAllPopovers = function() {
       $('.popup-marker').each(function() {
            $(this).popover('hide');
        });  
    };

    $('.popup-marker').popover({
        html: true,
        trigger: 'manual'
    }).on('click', function(e) {
        // if any other popovers are visible, hide them
        if(isVisible) {
            hideAllPopovers();
        }

        $(this).popover('show');

        // handle clicking on the popover itself
        $('.popover').off('click').on('click', function(e) {
            e.stopPropagation(); // prevent event for bubbling up => will not get caught with document.onclick
        });

        isVisible = true;
        e.stopPropagation();
    });


    $(document).on('click', function(e) {
        hideAllPopovers();
        isVisible = false;
    });
});

唯一需要注意的是，你将无法打开2个弹出窗口同一时间。但我觉得这对用户来说会让人感到困惑： - ）

The only caveat is that you won't be able to open 2 popovers at the same time. But I think that would be confusing for the user, anyway :-)
