Tumblr 风格的 UserHoverCard

Question

大家好，我对 ajax 悬停有一个问题。我正在尝试制作像 tumblr 这样的 userHoverCard。但是当我将它与 ajax 一起使用时，悬停动画不起作用。

这是工作 DEMO 没有 ajax 只有 css。在这个演示中，您可以看到当您悬停图像时，.p-tooltip 将以动画效果打开。

但是如果你从我的测试页面点击这个DEMO然后你可以看到当你悬停图像时.p-tooltip将不会以动画效果打开。

HTML

    <div class="p-tooltip"></div>
    <div class="summary" data-id="25">
      <a href=#" class="profile-ava"></a>
    </div>
    <div class="summary" data-id="20">
      <a href=#" class="profile-ava"></a>
    </div>
    <div class="summary" data-id="25">
      <a href=#" class="profile-ava"></a>
    </div>

这是我的 ajax 代码：

$(document).ready(function() { 

        function showProfileTooltip(e, id){ 
           e.append($('.p-tooltip').css({ 
             'top':'20', 
             'left':'80' 
             }).show()); 
            //send id & get info from get_profile.php 
             $.ajax({
             url: 'get_profile.php?uid='+id,
             beforeSend: function(){

             $('.p-tooltip').html('Loading..');
             },
             success: function(html){ 
             $('.p-tooltip').html(html); 
             } 
           }); 
         } 

        function hideProfileTooltip(){ 
        $('.p-tooltip').hide().fadeIn('fast'); 
         } 
        $('.summary a').hover(function(e){ 

          var id = $(this).attr('data-id'); 
          showProfileTooltip($(this), id); 

          }, function(){ 
          setTimeout(function(){ 
          hideProfileTooltip(); 
          },2000); 
         });
    });

这是 CSS 代码：

基本上，我已经创建了一个非常聪明的解决方法。它是一个遮罩，在加载 html 之前覆盖图像（不可见），然后在 z-index 降低后发生悬停 css。悬停的 javascript 在容器上。

FIDDLE

.summary {
    margin: -50px auto 0;
    width: 50px;
    height: 50px;
    position: relative;
    z-index: 0;
}
.summary-mask {
    margin: 50px auto 0;
    width: 50px;
    height: 50px;
    position: relative;
    z-index: 1;
}
.loaded .summary-mask {
    z-index: -1;
}

HTML

<div class="the-container">
    <div class="summary-mask"></div>
    <div class="summary" data-id="100"> <a href="http://kraigo.tumblr.com/" class="profile-ava"></a>

        <div class="user-container"></div>
    </div>
</div>

JS

var response = '<div class="p-tooltip"> <div class="profile-header"></div> <div class="profile-navigation"> <a href="http://kraigo.tumblr.com/" class="profile-action">Follow</a> <p class="profile-nick"> <a href="http://kraigo.tumblr.com/">Page Name</a> </p> </div> <div class="profile-ava"></div> <div class="profile-info"> <h1 class="profile-title">Username</h1> <p class="profile-description">Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry\'s standard dummy ..</p> </div> <ul class="profile-items"> <li></li> <li></li> <li></li> </ul> </div>';

$(document).ready(function () {

    function showProfileTooltip(e, id) {
        //send id & get info from get_profile.php 
        $.ajax({
            url: '/echo/html/',
            data: {
                html: response,
                delay: 0
            },
            method: 'post',
            success: function (returnHtml) {
                e.find('.user-container').html(returnHtml).promise().done(function () {
                    $('.the-container').addClass('loaded');
                });
            }
        });

    }

    function hideProfileTooltip() {
        $('.the-container').removeClass('loaded');
    }
    $('.the-container').hover(function (e) {

        var id = $(this).find('.summary').attr('data-id');
        showProfileTooltip($(this), id);

    }, function () {
        hideProfileTooltip();
    });
});

当您显示卡片时，它只包含加载消息。当内容到达并将其放入卡片中时，这不是 CSS 更改，因此不会激活过渡。

如果您等到内容到达才显示卡片，则可以制作动画。
