如何自定义Twitter Bootstrap popover隐藏动画 [英] How to customize Twitter Bootstrap popover hide animation

问题描述

我想实现自己的popover hide动画。目前，我正在修改bootstrap.js。

I would like to implement my own popover hide animation. Currently, I am modifying bootstrap.js directly.

$.fn.popover = function (option) {
            return this.each(function () {
                var $this = $(this)
                  , data = $this.data('popover')
                  , options = typeof option == 'object' && option
                if (!data) $this.data('popover', (data = new Popover(this, options)))

                //original code
                // if (typeof option == 'string') data[option]()
                //custom code
                if (typeof option == 'string') {
                    if (option === 'hide') {
                        //my customize animation here
                    }
                    else {
                        data[option]();
                    }

                }

            })
        }

我是谁我想知道是否还有，所以当我初始化popover时我可以实现动态动画

I would like to know if there are anyway so I can achieve a dynamic animation when I init the popover

$('#target').popover({
    hide: function () {
        //my own animation
    }
});

推荐答案

好问题 - 脑筋急转弯！你绝对可以做到。看一看如何在不破坏原始源代码的情况下扩展插件：

Nice question-brain-teaser! You can definitely do it. Take a look how you can extend plugin without messing with original source code:

$.fn.popover = function (orig) {
  return function(options) {
    return this.each(function() {
      orig.call($(this), options);
      if (typeof options.hide == 'function') {
        $(this).data('bs.popover').hide = function() {
          options.hide.call(this.$tip, this);
          orig.Constructor.prototype.hide.call(this);
        };
      }
    });
  }
}($.fn.popover);

我们走了！我们使用自己的扩展功能扩展了默认弹出框。现在让我们使用它：

Here we go! We extended default popover functionality with our own. Now lets use it:

$('.three').popover({
  placement: 'bottom',
  hide: function() {
    $(this).animate({marginTop: -100}, function() {
      $(this).css({marginTop: ''});
    });
  }
});

以上popover将在隐藏时具有自定义动画效果。

Above popover will have custom animation effect while hiding.

当然，如果你不提供隐藏选项，你将有默认行为。

Of course if you don't provide hide option you will have default behavior.
