How can I hold Twitter Bootstrap Popover open until my mouse moves into it?

问题

I have a link that uses the Twitter Bootstrap Popover version 1.3.0 to show some information. This information includes a link, but every-time I move my mouse from the link to the popover, the popover just disappears.

How can I hold popover open long enough to enable the mouse to move into it? Then when the mouse moves out of the link and popover, hide it?

Or is there some other plugin that can do this?

回答1:

With bootstrap (tested with version 2) I figured out the following code:

$("a[rel=popover]")
            .popover({
                offset: 10,
                trigger: 'manual',
                animate: false,
                html: true,
                placement: 'left',
                template: '<div class="popover" onmouseover="$(this).mouseleave(function() {$(this).hide(); });"><div class="arrow"></div><div class="popover-inner"><h3 class="popover-title"></h3><div class="popover-content"><p></p></div></div></div>'

            }).click(function(e) {
                e.preventDefault() ;
            }).mouseenter(function(e) {
                $(this).popover('show');
            });

The main point is to override template with mouseleave() enabler. I hope this helps.

Just to add to Marchello's example, if you want the popover to disappear if the user moves their mouse away from the popover and source link, try this out.

var timeoutObj;
$('.nav_item a').popover({
    offset: 10,
    trigger: 'manual',
    html: true,
    placement: 'right',
    template: '<div class="popover" onmouseover="clearTimeout(timeoutObj);$(this).mouseleave(function() {$(this).hide();});"><div class="arrow"></div><div class="popover-inner"><h3 class="popover-title"></h3><div class="popover-content"><p></p></div></div></div>'
}).mouseenter(function(e) {
    $(this).popover('show');
}).mouseleave(function(e) {
    var ref = $(this);
    timeoutObj = setTimeout(function(){
        ref.popover('hide');
    }, 50);
});

Bootstrap 3 and above

Simple, just use the container option and have it as the element that is calling the popover. This way, the popover is a child of the element that calls it. Hence, you are technically still hovering over the parent, because the child popover belongs to it.

For example:

HTML:

<div class="pop" data-content="Testing 12345">This has a popover</div>
<div class="pop" data-content="Testing 12345">This has a popover</div>
<div class="pop" data-content="Testing 12345">This has a popover</div>

jQuery:

Running an $.each() loop over every one of my elements that I want a popover binded to its parent. In this case, each element has the class of pop.

$('.pop').each(function () {
    var $elem = $(this);
    $elem.popover({
        placement: 'top',
        trigger: 'hover',
        html: true,
        container: $elem
    });
});

CSS:

This part is optional, but recommended. It moves the popover down by 7 pixels for easier access.

.pop .popover {
    margin-top:7px;
}

This is a little hacky, but building off of marchello's example, I did this (no need for template):

$(".trigger-link").popover({
  trigger: "manual",
}).on("click", function(e) {
  e.preventDefault();
}).on("mouseenter", function() {
  var _this = this;
  $(this).popover("show");
  $(this).siblings(".popover").on("mouseleave", function() {
    $(_this).popover('hide');
  });
}).on("mouseleave", function() {
  var _this = this;
  setTimeout(function() {
    if (!$(".popover:hover").length) {
      $(_this).popover("hide")
    }
  }, 100);
});

The setTimeout helps ensure that there's time to travel from the trigger link to the popover.

This issue on the bootstrap github repo deals with this problem. fat pointed out the experimental "in top/bottom/left/right" placement. It works, pretty well, but you have to make sure the popover trigger is not positioned statically with css. Otherwise the popover won't appear where you want it to.

HTML:

<span class="myClass" data-content="lorem ipsum content" data-original-title="pop-title">Hover me to show a popover.</span>

CSS:

/*CSS */
.myClass{ position: relative;}

JS:

$(function(){
  $('.myClass').popover({placement: 'in top'});
});

Here's my take: http://jsfiddle.net/WojtekKruszewski/Zf3m7/22/

Sometimes while moving mouse from popover trigger to actual popover content diagonally, you hover over elements below. I wanted to handle such situations – as long as you reach popover content before the timeout fires, you're save (the popover won't disappear). It requires delay option.

This hack basically overrides Popover leave function, but calls the original (which starts timer to hide the popover). Then it attaches a one-off listener to mouseenter popover content element's.

If mouse enters the popover, the timer is cleared. Then it turns it listens to mouseleave on popover and if it's triggered, it calls the original leave function so that it could start hide timer.

var originalLeave = $.fn.popover.Constructor.prototype.leave;
$.fn.popover.Constructor.prototype.leave = function(obj){
  var self = obj instanceof this.constructor ?
    obj : $(obj.currentTarget)[this.type](this.getDelegateOptions()).data('bs.' + this.type)
  var container, timeout;

  originalLeave.call(this, obj);

  if(obj.currentTarget) {
    container = $(obj.currentTarget).siblings('.popover')
    timeout = self.timeout;
    container.one('mouseenter', function(){
      //We entered the actual popover – call off the dogs
      clearTimeout(timeout);
      //Let's monitor popover content instead
      container.one('mouseleave', function(){
        $.fn.popover.Constructor.prototype.leave.call(self, self);
      });
    })
  }
};

Solution worked for us for Bootstrap 3.

var timeoutObj;
$('.list-group a').popover({
    offset: 10,
    trigger: 'manual',
    html: true,
    placement: 'right',
    template: '<div class="popover" onmouseover="$(this).mouseleave(function() {$(this).hide();});"><div class="arrow"></div><div class="popover-inner"><h3 class="popover-title"></h3><div class="popover-content"><p></p></div></div></div>'
}).mouseenter(function(e) {
    $(this).popover('show');
}).mouseleave(function(e) {
    var _this = this;
    setTimeout(function() {
        if (!$(".popover:hover").length) {
            $(_this).popover("hide");
        }
    }, 100);
}); 

回答8:

Finally I fix this problem. Popover disappear is because Popover not child node of link, it is child node of body.

So fix it is easy, change bootstrap-twipsy.js content:

change .prependTo(document.body) to .prependTo(this.$element)

and fix position problem cause by change.

and some use link tiger popover will cause popover with link too, so add a span contain link, so problem solved.

This is a version of Wojtek Kruszewski solution. This version handle popover blink when mouse go back to trigger. http://jsfiddle.net/danielgatis/QtcpD/

(function($) {
      var originalLeave = $.fn.popover.Constructor.prototype.leave;
      $.fn.popover.Constructor.prototype.leave = function(obj) {
        var self = (obj instanceof this.constructor ? obj : $(obj.currentTarget)[this.type](this.getDelegateOptions()).data("bs." + this.type));
        originalLeave.call(this, obj);
        if (obj.currentTarget) {
          var current = $(obj.currentTarget);
          var container = current.siblings(".popover");
          container.on("mouseenter", function() {
            clearTimeout(self.timeout);
          });
          container.on("mouseleave", function() {
            originalLeave.call(self, self);
          });
        }
      };

      var originalEnter = $.fn.popover.Constructor.prototype.enter;
      $.fn.popover.Constructor.prototype.enter = function(obj) {
        var self = (obj instanceof this.constructor ? obj : $(obj.currentTarget)[this.type](this.getDelegateOptions()).data("bs." + this.type));
        clearTimeout(self.timeout);
        if (!$(obj.currentTarget).siblings(".popover:visible").length) {
          originalEnter.call(this, obj);
        }
      };
    })(jQuery);

I tried the solutions from @Wotjek Kruszewski and @danielgatis, but neither worked for me. Caveat: I'm using Bootstrap v2.1.0, not v3. This solution is in coffeescript (why are people still using plain javascript? =)).

(($) ->
  originalLeave = $.fn.popover.Constructor::leave
  $.fn.popover.Constructor::leave = (e) ->
    self = $(e.currentTarget)[@type](@_options).data(@type)
    originalLeave.call @, e

    if e.currentTarget
      container = $(".popover")
      container.one "mouseenter", ->
        clearTimeout self.timeout

        container.one "mouseleave", ->
          originalLeave.call self, e
) jQuery

回答11:

Here is what i did:

e = $("a[rel=popover]")
e.popover({
    content: d, 
    html:true, 
    trigger:'hover',
    delay: {hide: 500},
    placement: 'bottom',
    container: e, 
})

This is a very simple and awesone solution to this probelm, which i found out by looking into the bootstrap tooltip code. In Bootstrap v3.0.3 here is the line of code i noticed:

this.options.container ? $tip.appendTo(this.options.container) : $tip.insertAfter(this.$element)

this says that if container property of popover is defined then the popover gets appendTo() the element instead of insertAfter() the original element, all you need to do is just pass the element as container property. Because of appendTo() the popover becomes part of the link on which the hover event was binded and thus keeps the popover open when mouse moves on it.

回答12:

This works for me on BootStrap 3:

el.popover({
  delay: {hide: 100}
}).on("shown.bs.popover", function(){
  el.data("bs.popover").tip().off("mouseleave").on("mouseleave", function(){
    setTimeout(function(){
      el.popover("hide");
    }, 100);
  });
}).on("hide.bs.popover", function(ev){
  if(el.data("bs.popover").tip().is(":hover"))
    ev.preventDefault();
});

回答13:

At the end of the conversation linked by @stevendaniels is a link to a Twitter Bootstrap extension called BootstrapX - clickover by Lee Carmichael. This changes the popover from an overlarge tooltip into an interactive control, which can be closed by clicking elsewhere on the form, a close button, or after a timeout. Its easy to use, and worked very well for the project I needed it in. Some examples of its usage can be found here.

回答14:

I didn't like any of the answers I've found, so I combined some answers that were close to make the following code. It allows you to end up just typing $(selector).pinnablepopover(options); every time you want to make a 'pinnable' popover.

Code that makes things easy:

$.fn.popoverHoverShow = function ()
{
    if(this.data('state') !== 'pinned')
    {
        if(!this.data('bs.popover').$tip || (this.data('bs.popover').$tip && this.data('bs.popover').$tip.is(':hidden')))
        {
            this.popover('show');
        }
    }
};
$.fn.popoverHoverHide = function ()
{
    if (this.data('state') !== 'pinned')
    {
        var ref = this;
        this.data('bs.popover').$tip.data('timeout', setTimeout(function(){ ref.popover('hide') }, 100))
        .on('mouseenter', function(){ clearTimeout($(this).data('timeout')) })
        .on('mouseleave', function(){ $(this).data('timeout', setTimeout(function(){ ref.popover('hide') }, 100)) });
        this.on('mouseenter', function(){ clearTimeout($(this).data('timeout')) });
    }
};
$.fn.popoverClickToggle = function ()
{
    if (this.data('state') !== 'pinned')
    {
        this.data('state', 'pinned');
    }
    else
    {
        this.data('state', 'hover')
    }
};
$.fn.pinnablepopover = function (options)
{
    options.trigger = manual;
    this.popover(options)
    .on('mouseenter', function(){ $(this).popoverHoverShow() })
    .on('mouseleave', function(){ $(this).popoverHoverHide() })
    .on('click', function(){ $(this).popoverClickToggle() });
};

Example usage:

$('[data-toggle=popover]').pinnablepopover({html: true, container: 'body'});
