如何通过单击外部消除Twitter Bootstrap弹出窗口?

问题描述：

我们可以使弹出窗口与模式一样被消除吗?当用户单击它们外部的某个位置时使它们关闭?

Can we get popovers to be dismissable in the same way as modals, ie. make them close when user clicks somewhere outside of them?

不幸的是，我不能只使用真实的模式而不是popover，因为modal意味着position:fixed，这将不再是popover. :(

Unfortunately I can't just use real modal instead of popover, because modal means position:fixed and that would be no popover anymore. :(

更新:更为健壮的解决方案:

Update: A slightly more robust solution: http://jsfiddle.net/mattdlockyer/C5GBU/72/

对于仅包含文本的按钮:

For buttons containing text only:

$('body').on('click', function (e) {
    //did not click a popover toggle or popover
    if ($(e.target).data('toggle') !== 'popover'
        && $(e.target).parents('.popover.in').length === 0) { 
        $('[data-toggle="popover"]').popover('hide');
    }
});

对于包含图标的按钮，请使用(此代码在Bootstrap 3.3.6中存在错误，请参见此答案中的以下修复程序)

For buttons containing icons use (this code has a bug in Bootstrap 3.3.6, see the fix below in this answer)

$('body').on('click', function (e) {
        //did not click a popover toggle, or icon in popover toggle, or popover
        if ($(e.target).data('toggle') !== 'popover'
            && $(e.target).parents('[data-toggle="popover"]').length === 0
            && $(e.target).parents('.popover.in').length === 0) { 
            $('[data-toggle="popover"]').popover('hide');
        }
    });

对于JS生成的弹出窗口，请使用'[data-original-title]'代替'[data-toggle="popover"]'

注意事项:以上解决方案允许一次打开多个弹出窗口.

Caveat: The solution above allows multiple popovers to be open at once.

请一次弹出一个弹出窗口:

更新:Bootstrap 3.0.x，请参见代码或拨弄 http://jsfiddle.net/mattdlockyer/C5GBU/2/

Update: Bootstrap 3.0.x, see code or fiddle http://jsfiddle.net/mattdlockyer/C5GBU/2/

$('body').on('click', function (e) {
    $('[data-toggle="popover"]').each(function () {
        //the 'is' for buttons that trigger popups
        //the 'has' for icons within a button that triggers a popup
        if (!$(this).is(e.target) && $(this).has(e.target).length === 0 && $('.popover').has(e.target).length === 0) {
            $(this).popover('hide');
        }
    });
});

这将处理已打开但未单击的弹出窗口或未单击其链接的弹出窗口.

This handles closing of popovers already open and not clicked on or their links have not been clicked.

更新:引导程序3.3.6，参见小提琴

Update: Bootstrap 3.3.6, see fiddle

修复了关闭后需要2次点击才能重新打开的问题

Fixes issue where after closing, takes 2 clicks to re-open

$(document).on('click', function (e) {
    $('[data-toggle="popover"],[data-original-title]').each(function () {
        //the 'is' for buttons that trigger popups
        //the 'has' for icons within a button that triggers a popup
        if (!$(this).is(e.target) && $(this).has(e.target).length === 0 && $('.popover').has(e.target).length === 0) {                
            (($(this).popover('hide').data('bs.popover')||{}).inState||{}).click = false  // fix for BS 3.3.6
        }

    });
});

更新:使用之前的改进条件，此解决方案得以实现.解决了双击和幻影弹出窗口的问题:

Update: Using the conditional of the previous improvement, this solution was achieved. Fix the problem of double click and ghost popover:

$(document).on("shown.bs.popover",'[data-toggle="popover"]', function(){
    $(this).attr('someattr','1');
});
$(document).on("hidden.bs.popover",'[data-toggle="popover"]', function(){
    $(this).attr('someattr','0');
});
$(document).on('click', function (e) {
    $('[data-toggle="popover"],[data-original-title]').each(function () {
        //the 'is' for buttons that trigger popups
        //the 'has' for icons within a button that triggers a popup
        if (!$(this).is(e.target) && $(this).has(e.target).length === 0 && $('.popover').has(e.target).length === 0) {
            if($(this).attr('someattr')=="1"){
                $(this).popover("toggle");
            }
        }
    });
});
