这是一款基于velocity.js过渡动画效果的Bootstrap模态窗口和Popover。该效果在Bootstrap模态窗口和Popover的基础上，使用velocity.js来制作模态窗口和Popover打开时的动画过渡效果。

使用方法

HTML结构

模态窗口和Popover的基本HTML结构如下。

<!-- 模态窗口 -->
<a href="#myModal1" role="button" data-target="#myModal1" class="btn btn-default" data-toggle="modal">fadeIn</a>
<div id="myModal1" class="modal" data-easein="fadeIn" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="false">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h4 class="modal-title" id="myModalLabel">Modal header 1</h4>
      </div>
      <div class="modal-body">
        <p>One fine body…</p>
      </div>
      <div class="modal-footer">
        <button class="btn btn-default" data-dismiss="modal" aria-hidden="true">Close</button>
        <button class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

<!-- popover -->
<a data-original-title="Popover on top" data-animation="false" data-easein="fadeIn" href="#" class="btn btn-primary" rel="popover" data-placement="top" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">fadeIn</a>
JavaScript

该特效使用下面的javascript代码来为Bootstrap模态窗口和Popover打开时添加velocity.js的过渡动画效果。

// add the animation to the popover
$('a[rel=popover]').popover().click(function(e) {
  e.preventDefault();
  var open = $(this).attr('data-easein');
  if (open == 'shake') {
    $(this).next().velocity('callout.' + open);
  } else if (open == 'pulse') {
    $(this).next().velocity('callout.' + open);
  } else if (open == 'tada') {
    $(this).next().velocity('callout.' + open);
  } else if (open == 'flash') {
    $(this).next().velocity('callout.' + open);
  } else if (open == 'bounce') {
    $(this).next().velocity('callout.' + open);
  } else if (open == 'swing') {
    $(this).next().velocity('callout.' + open);
  } else {
    $(this).next().velocity('transition.' + open);
  }

});

// add the animation to the modal
$(".modal").each(function(index) {
  $(this).on('show.bs.modal', function(e) {
    var open = $(this).attr('data-easein');
    if (open == 'shake') {
      $('.modal-dialog').velocity('callout.' + open);
    } else if (open == 'pulse') {
      $('.modal-dialog').velocity('callout.' + open);
    } else if (open == 'tada') {
      $('.modal-dialog').velocity('callout.' + open);
    } else if (open == 'flash') {
      $('.modal-dialog').velocity('callout.' + open);
    } else if (open == 'bounce') {
      $('.modal-dialog').velocity('callout.' + open);
    } else if (open == 'swing') {
      $('.modal-dialog').velocity('callout.' + open);
    } else {
      $('.modal-dialog').velocity('transition.' + open);
    }

  });
});
