引导弹出:悬停/单击并在外部单击时关闭,但恢复到悬停模式

twitter-bootstrap-3 twitter-bootstrap jquery

gene b. · 技术社区 · 7 年前

在下面的代码片段中,我有一个引导弹出窗口,它支持悬停和单击模式。单击时,窗口保持打开状态,并应在(1)自我单击(再次链接)或(2)任何外部单击时关闭。

问题:单击外部后,弹出窗口转到“ 目前开放 “模式。这意味着如果你再次在它上面徘徊,窗户就会卡住,不会消失。应该发生的是,在外部单击之后,当再次将鼠标悬停在原始悬停和消失模式上时,您将恢复到该模式。此处的行为与在内部关闭单击(即原始状态)后悬停时的行为相同。我忘了什么吗?

$('#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。我更改了您的条件语句,以检查用户是否单击了Popover触发器的外部。如果Popover可见,则触发 click 弹出触发器的事件。

我想这么做是因为 点击 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了 Maximum call stack size exceeded 当有超过1个弹出窗口时,由于无限循环而导致的错误(请参阅我的第一个答案和注释)。

为了解决这个问题:我使用 .off 每当系统将要执行 trigger('click') . 之后,我重新初始化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();
        }
    });
});

});

实际上,我解决了Eminemmeim原始答案中的无限循环(由于 trigger('click') )通过在 body.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,我们就忽略了规则逻辑。

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);
          }
        });
      }
    }
});
