css转换不能与jquery一起运行

Question

我试图将css过渡效果添加到元素中，如下所示：

＆＃13;

＆＃13;

$('.trans-opener').click(function () {
    $(this).nextAll().slice(0, 3).toggleClass('trans-hidden');
});

＆＃13;

.row{
  padding: 50px;
  }
.trans-hidden {
    display: none;
    position: absolute;
    right: 15px;
}
ul{
    list-style:none;
    margin:0px;
    padding:0px;
}
ul li {
    float: right;
    padding-left: 15px;
}
ul li .icon {
    height: 32px;
    width: 32px;
    background-color: #cdcdcd;
    line-height: 35px;
    border-radius: 50%;
    transition: all 0.3s;
}

＆＃13;

<div class="row">
    <div class="col-xs-3">
        <div></div>
    </div>
    <div class="col-xs-9">
        <ul>
            <li class="trans-opener"><a href="#"><div class="icon"><i class="fa fa-ellipsis-h"></i></div></a>

            </li>
            <li class="trans-hidden"><a href="#"><div class="icon"><i class="fa fa-facebook"></i></div></a>

            </li>
            <li class="trans-hidden"><a href="#"><div class="icon"><i class="fa fa-twitter"></i></div></a>

            </li>
            <li class="trans-hidden"><a href="#"><div class="icon"><i class="fa fa-heart"></i></div></a>

            </li>
        </ul>
    </div>
</div>

＆＃13;

＆＃13;

＆＃13;

当我点击（...）三点图标时，会出现其他图标。但我试图给图标赋予过渡效果。我试过了transition: all 0.3s;，但它没有用。任何帮助都会非常明显。

使用jQuery fadeIn()函数可能会更容易实现，如下所示：

$('.trans-opener').click(function () {
    $(this).nextAll().slice(0, 3).fadeToggle();
});

.row{
  padding: 50px;
  }
.trans-hidden {
    display: none;
    /*position: absolute;*/
    right: 15px;
}
ul{
    list-style:none;
    margin:0px;
    padding:0px;
}
ul li {
    float: right;
    padding-left: 15px;
}
ul li .icon {
    height: 32px;
    width: 32px;
    background-color: #cdcdcd;
    line-height: 35px;
    border-radius: 50%;
    transition: all 0.3s;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="row">
    <div class="col-xs-3">
        <div></div>
    </div>
    <div class="col-xs-9">
        <ul>
            <li class="trans-opener"><a href="#"><div class="icon"><i class="fa fa-ellipsis-h"></i></div></a>

            </li>
            <li class="trans-hidden"><a href="#"><div class="icon"><i class="fa fa-facebook"></i></div></a>

            </li>
            <li class="trans-hidden"><a href="#"><div class="icon"><i class="fa fa-twitter"></i></div></a>

            </li>
            <li class="trans-hidden"><a href="#"><div class="icon"><i class="fa fa-heart"></i></div></a>

            </li>
        </ul>
    </div>
</div>

如果您希望它们展开（即向右移动），您需要单独指定每个位置。试试这个：

$('.trans-opener').click(function () {
  var icons = $(this).nextAll().slice(0, 3)
  if(icons.is(":visible")){
    $(icons).animate({right: 60}, function(){ icons.toggle(); });
  }
  else{
    icons.toggle();
    $(icons[0]).animate({right: 200});
    $(icons[1]).animate({right: 150});
    $(icons[2]).animate({right: 100});
  }
});

.row{
  padding: 50px;
  }
.trans-hidden {
    display: none;
    position: absolute;
    right: 60px;
}
ul{
    list-style:none;
    margin:0px;
    padding:0px;
}
ul li {
    float: right;
    padding-left: 15px;
}
ul li .icon {
    height: 32px;
    width: 32px;
    background-color: #cdcdcd;
    line-height: 35px;
    border-radius: 50%;
    transition: all 0.3s;
}

    </div>
    <div class="col-xs-9">
        <ul>
            <li class="trans-opener"><a href="#"><div class="icon"><i class="fa fa-ellipsis-h"></i></div></a>

            </li>
            <li class="trans-hidden"><a href="#"><div class="icon"><i class="fa fa-facebook"></i></div></a>

            </li>
            <li class="trans-hidden"><a href="#"><div class="icon"><i class="fa fa-twitter"></i></div></a>

            </li>
            <li class="trans-hidden"><a href="#"><div class="icon"><i class="fa fa-heart"></i></div></a>

            </li>
        </ul>
    </div>

您可以使用关键帧，使图标可设置为动画，首先必须在动画的早期阶段设置display：block。对于fadeIn动画，您可以使用。

ul li .icon {
        height: 32px;
        width: 32px;
        background-color: #cdcdcd;
        line-height: 35px;
        border-radius: 50%;
        animation: fadeInCustom 1s;
    }

@keyframes fadeInCustom {
        0% {
            display: none;
            opacity: 0;
        }

        1% {
            display: block;
            opacity: 0;
        }

        100% {
            display: block;
            opacity: 1;
        }
}
