利⽤CSS动画制作Html表格数据滚动显⽰
直接上图看最终实现效果：
DataV⾥有这个效果，看起来⾼⼤上，实际⾃⼰开发也不难实现。实现的⽅法很多，下⾯是本⼈的⼀种实现⽅案，分享给⼤家。
这个效果需要解决2个问题：
1：⾸尾的数据衔接；
2：css动画实现；
⾸先利⽤js 构造⼀些数据；
Html 结构如下：
<div class="table-title">
<span > 序号</span>
<span > 列2</span>
<span > 列3</span>
<span > 列4</span>
</div>
<div id="data-wrapper1" class="data-content">
</div>
js 构造⾏数据，奇数⾏和偶数⾏数据样式不⼀样⽽已：注意为了⾸尾衔接的特殊处理，就是在数据结束的尾部刻意追加⾸先开始的设定N⾏
数据；
var buildRow = function () {
var htmlTemplate = '<div class="{0}"><span class="td-col1">{1}</span><span class="td-col2"> xxx</span><span class="td-col3">⾏数据</span><span class= var wrapper = $("#data-wrapper1");
for (var i = 0; i < 15; i++) {
var cls = "table-row-odd";
if (i % 2 === 0) {
cls = "table-row-even";
}
wrapper.append(htmlTemplate.format([cls, (i + 1).toString()]));
}
// 为了让⾸尾动画衔接上，在数据⾏的末尾追加开头的N⾏数据
for (var j = 0; j < rownumber; j++) {
cls = "table-row-odd";
if (j % 2 === 0) {
cls = "table-row-even";
}
wrapper.append(htmlTemplate.format([cls, (j+1).toString()]));
}
};
关键的部分就是Js实现了：
var startDataCollapse = function () {
var divs = $("#data-wrapper1").find("div");
var divlen = divs.length;
var scroll_total = il(divlen / rownumber);
var times = 1;
if (scroll_total > 1) {
setInterval(function () {
$.each(divs, function (i, itm) {
if (!$(itm).hasClass("data-collapse") && i < times * rownumber) {
$(itm).addClass("data-collapse");
}
});
if (times === scroll_total) {
times = 1;
$.each(divs, function (i, itm) {
$(itm).removeClass("data-collapse");
});
setTimeout(function () {
doDataCollapse();
}, 500);// 延迟执⾏刚好为 css动画的执⾏时间
} else {
times++;
}
}, 2000);
}
};
下⾯的这个函数作⽤为：当全部⾏css动画执⾏完后，最后⼀屏动画执⾏需要0.5s，所以延迟0.5s秒后
⽴即执⾏刚被还原的第⼀屏数据的动画，这样下⼀个time interval的时候直接就是从第⼆屏开始动画了，基于这个实现，⾸尾的动画就衔接上了。关键部分就在于此。
var doDataCollapse = function () {
var divsNew = $("#data-wrapper1").find("div");
$.each(divsNew, function (i, itm) {
if (!$(itm).hasClass("data-collapse") && i < rownumber) {
$(itm).addClass("data-collapse");
}
});
};
最后看下CSS动画实现部分：
/*#region Css collapse */
.data-content {
height: 250px;
overflow-y: hidden;
}
.table-title {
height: 50px;
line-height: 50px;
background-color: #2688e6;
font-size: 16px;
color: #fff;
}
.
data-content .table-row-even {
height: 50px;
line-height: 50px;
background-color: #002d36;
font-size: 0;
}
}
.data-content .table-row-odd {
height: 50px;
line-height: 50px;
background-color: #003e52;
font-size: 0;
}
.data-content .td-col1 {
display: inline-block;
width: 10%;
font-size: 16px;
color: #fff;
text-align:center;
}
.data-content .td-col2 {
display: inline-block;
width: 20%;
font-size: 16px;
color: #fff;
}
.data-content .td-col3 {
display: inline-block;
width: 30%;
font-size: 16px;
color: #fff;
}
.data-content .td-col4 {
display: inline-block;
width: 40%;
font-size: 16px;
color: #fff;
}
.data-collapse {
animation: data-col .5s;
animation-timing-function: ease; animation-fill-mode: forwards;
overflow:hidden;
}
@keyframes data-col {
from {
height: 50px;
}
to {
height: 0;
}
}
/*#endregion */
更新：再来看⼀个vue版本的实现：
<div id="dataWrapper" class="data-content">
<div v-for="(f,index) in infos" :key="index" :class="index%2==0?'table-row-odd':'table-row-even'"> <span class="td-col td2-col0">{{f.id}}</span>
<span class="td-col td2-col1">{{f.device}}</span>
<span class="td-col">{{f.content}}</span>
</div>
</div>
