Bootstrap Popover：悬停/单击并关闭外部单击，但恢复为悬停模式

提问于

在下面的代码片段中，我有一个Bootstrap Popover，它支持Hover和Click模式 . 单击时，窗口保持打开状态，应关闭（1）自我点击（再次链接），或（2）任何外部点击 .

问题：外部点击后，弹出窗口进入“ currently open ”模式 . 这意味着如果再次将鼠标悬停在窗口上，则窗口会卡住并且不会消失 . 应该发生的是，在外部点击后，当您再次将鼠标悬停在其上时，您将恢复为原始的悬停和消失模式 . 这里的行为与在内部关闭点击（原始状态）之后悬停时相同 . 我忘记了什么吗？

$('#linkPopover').popover({
  trigger: 'hover click', 
  content: 'This is my content', 
  title: 'TITLE'
});

// -----------------
// Just with the above (and no other code), the Hover and Click-Toggle 
// works within the SAME Popover window,
// but now I need to also remove the visible Popover on ANY CLICK OUTSIDE.

// However, although the below works, *after* clicking outside the Popover is in the CLICKED 
// mode i.e. it doesn't hover anymore

$('body').on('click', function(e) {
	    $('[data-toggle="popover"]').each(function () {
	        if (!$(this).is(e.target) && $(this).has(e.target).length === 0 && $('.popover').has(e.target).length === 0) {
              // From outside click with the popover open, need to hide
	            $(this).popover('hide');
	        }	    	
	    });  
});

    此代码可能对您有所帮助 . 我更改了条件语句，以检查用户是否在popover触发器外部单击&&如果弹出窗口可见，则触发弹出窗口触发器的 click 事件 .

    我想这样做是因为 click 事件是单击触发器本身时发生的事件 .

    $(document).ready(function(){

$('#linkPopover').popover({
  trigger: 'hover click',
  content: 'This is my content', 
  title: 'TITLE'
});

$('body').on('click', function(e) {
    $('[data-toggle="popover"]').each(function () {
        if(!$(this).is(e.target) && ($("#linkPopover").next('div.popover:visible').length)){
        $("#linkPopover").trigger('click');
    }
    });
});

});

    我的第一个答案产生 Maximum call stack size exceeded 错误，因为有超过1个弹出窗口时无限循环（请参阅我的第一个答案和注释） .

    要解决这个问题：每当系统要执行 trigger('click') 时，我在body click处理程序上使用 .off . 之后，我重新初始化了body click处理程序 . 见下面的示例 .

    $(document).ready(function(){

function initializeClick(){
$('body').on('click', function(e) {
    $('[data-toggle="popover"]').each(function () {
        if(!$(this).is(e.target) && ($(this).next('div.popover:visible').length)){
        $('body').off('click');
        $(this).trigger('click');
        initializeClick();
        }
    });
});
}

$('#linkPopover').popover({
  trigger: 'hover click',
  content: 'This is my content', 
  title: 'TITLE'
});

$('#linkPopover2').popover({
  trigger: 'hover click',
  content: 'This is my content', 
  title: 'TITLE'
});

$('body').on('click', function(e) {
    $('[data-toggle="popover"]').each(function () {
        if(!$(this).is(e.target) && ($(this).next('div.popover:visible').length)){
        $('body').off('click');
        $(this).trigger('click');
        initializeClick();
        }
    });
});

});

    我实际上通过在 body.click 中引入自定义标志参数来解决eminememinem原始答案中的无限循环（由于 trigger('click') ） . 你可以这样做

    $('body').on('click', function (e, manualClickTriggered) {

    我们在自己重新触发的特殊情况下设置了标志 . 如果是这样，我们忽略常规逻辑 .

    完整片段：

    $('[id*="linkPopover"]').popover({
  trigger: 'hover click', 
  content: 'This is my content', 
  title: 'TITLE'
});

// Close any visible popover if clicked outside 
// The "manualClickTriggered" flag indicates that we initiated the special Click event ourselves in order to turn off the popover, in which case skip the regular logic.
$('body').on('click', function (e, manualClickTriggered) {
  var linkId = null;
  if (e.target.id.indexOf("linkPopover") != -1) {
    linkId = e.target.id;
  }
		
  if (manualClickTriggered != true) {
    if (e.target.id.indexOf("linkPopover") == -1) {  // Not coming from any Popover Link (outside click) 
      $('a[id^="linkPopover"][data-toggle="popover"]').each(function () {	    	
        if( !$(this).is(e.target) && ($(this).next('div.popover:visible').length )) {
          $(this).trigger('click', true);
        }
      });
    }
    else // Coming from some Popover link
    {
        $('a[id^="linkPopover"][data-toggle="popover"]').each(function () {
          if ($(this).attr('id') != linkId && $(this).next('div.popover:visible').length) {
            $(this).trigger('click', true);
          }
        });
      }
    }
});
