问题

我希望在<details>标记的结束事件上播放动画。我认为只要恢复开放的动画就能完成这项工作，但不幸的是，没有。

$(function() {
  $('details').on('mouseover', function() {
    $(this).attr('open', true);
  }).on('mouseout', function() {
    $(this).attr('open', false);
  }).on('click', function(e) {
    e.preventDefault();
  })
});

details[open] SUMMARY~* {
  animation: sweepin .5s ease-in-out;
}

details[close] SUMMARY~* {
  animation: sweepout .5s ease-in-out;
}

@keyframes sweepin {
  0% {
    opacity: 0;
    margin-left: -10px
  }
  100% {
    opacity: 1;
    margin-left: 0px
  }
}

@keyframes sweepout {
  0% {
    opacity: 1;
    margin-left: 0px
  }
  100% {
    opacity: 0;
    margin-left: -10px
  }
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<details>
  <summary>Here my little summary</summary>
  <p>... Do you want more details?</p>
  <p>Here have some details!</p>
</details>

问题

你认为这是可能的吗？

Answer 1

您可以替换为.className选择器切换details[close];在mouseover事件检查，如果元素不是.open，如果是true，请在.open = true事件添加mouseout将属性设置为.className，请使用{{ 1}} .one()事件要移除animationend并在事件处理程序中将.className设置为.open。

false

＆＃13;

$(function() {
  $("details").on({
    mouseover: function() {
      if (!this.open && !$(this).is(".close"))
        $(this).prop("open", true)
        .one("animationend", function() {
          $(this).addClass("animationDone")
        })
    },
    mouseout: function _close() {
      if (!$(this).is(".close") && $(this).is(".animationDone"))
        $(this).addClass("close")
        .one("animationend", function() {
          $(this).prop("open", false)
          .removeClass("close animationDone")
        })
    },
    click: function(e) {
      e.preventDefault();
    }
  })
});

＆＃13;

details[open] SUMMARY~* {
  animation: sweepin .5s ease-in-out;
}

details.close SUMMARY~* {
  animation: sweepout .5s ease-in-out;
}

@keyframes sweepin {
  0% {
    opacity: 0;
    margin-left: -10px
  }
  100% {
    opacity: 1;
    margin-left: 0px
  }
}

@keyframes sweepout {
  0% {
    opacity: 1;
    margin-left: 0px
  }
  100% {
    opacity: 0;
    margin-left: -10px
  }
}

很抱歉改变逻辑，但我发现这更快更流畅。

$(function() {

  $('#summary').on('mouseover', function() {
  
    $('#triangleDown').fadeIn(0);
    $('#triangle').fadeOut(0);
    $('#content').addClass("open");
    
  }).on('mouseout', function() {
  
    $('#triangleDown').fadeOut(0);
    $('#triangle').fadeIn(0);
    $('#content').removeClass("open");
    
  })
  
});

#triangleDown{
  display:none;
}

span{
  font-size: 12px;
}

#content{
  
  opacity:0;
  margin-left: 0px;
  -webkit-transition:all 1s;
  transition:all 1s;
  
}

#content.open{
    opacity: 1;
    margin-left: 20px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
  <p id="summary"><span id="triangle">► </span><span id="triangleDown">▼ </span>Here my little summary</p>
  <div id="content">
  <p>... Do you want more details?</p>
  <p>Here have some details!</p>
  </div>
  
</div>

您可以使用动画填充模式属性在动画完成后保留div的原始位置。在鼠标悬停和鼠标移出事件中，您可以添加和删除打开和关闭属性。

请参阅下面的代码段

$(function() {
  $('details').on('mouseover', function() {
   $(this).attr('open', true);
   $(this).removeAttr('close', false);


  }).on('mouseout', function() {
 
      $(this).attr('open', false);
            $(this).removeAttr('open', false);
            $(this).attr('close', true);
 


  }).on('click', function(e) {
    e.preventDefault();
  })
});

details[open] SUMMARY~* {
  animation: sweepin .5s ease-in-out;
    animation-fill-mode:forwards;
}

details[close] SUMMARY~* {
  animation: sweepout .5s ease-in-out;
  animation-fill-mode:forwards;
}

@keyframes sweepin {
  0% {
    opacity: 0;
    margin-left: -10px
  }
  100% {
    opacity: 1;
    margin-left: 0px
  }
}

@keyframes sweepout {
  0% {
    opacity: 1;
    margin-left: 0px;
  }
  100% {
    opacity: 0;
    margin-left: -10px
  }
}
details{
border:solid red;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<details>
  <summary>Here my little summary</summary>
  <p>... Do you want more details?</p>
  <p>Here have some details!</p>
</details>
