jQuery achieves seamless scrolling of tables

This article example shares the specific code of jQuery to achieve seamless scrolling of the table for your reference. The specific content is as follows

For the css part, I used elastic layout

*{
            margin:0;
            padding:0;
        }
        ul,li{
            list-style:none;
        }
        .tableBox{
            width:500px;
            height:520px;
            background:#e8e8e8;
            margin:0 auto;
            overflow:hidden;
        }
        .slide-title{
            height:2.5rem;
            line-height:2.5rem;
            display:flex;
            background:#223e80;
            color:#fff;
            text-align:center;
        }
        .slide-title span{
            flex:1;
        }
        .slide-list li{
            line-height:1.875rem;
            height:1.875rem;
            display:flex;
        }
        .slide-list li span{
            flex:1;
            text-align:center;
        }
        .slide-list li.odd{
            background:rgba(0,0,0,.3)
        }

Structure

<div class="tableBox">
    <div class="slide-title">
        <span>title1</span>
        <span>title2</span>
        <span>title3</span>
    </div>
    <div class="slide-container">
        <ul class="slide-list js-slide-list">
            <li class="odd"><span>item1</span><span>item1</span><span>item1</span></li>
            <li class="even"><span>item2</span><span>item2</span><span>item2</span></li>
            <li class="odd"><span>item3</span><span>item3</span><span>item3</span></li>
            <li class="even"><span>item4</span><span>item2</span><span>item2</span></li>
            <li class="odd"><span>item5</span><span>item3</span><span>item3</span></li>
            <li class="even"><span>item6</span><span>item2</span><span>item2</span></li>
            <li class="odd"><span>item7</span><span>item3</span><span>item3</span></li>
            <li class="even"><span>item8</span><span>item2</span><span>item2</span></li>
            <li class="odd"><span>item9</span><span>item3</span><span>item3</span></li>
            <li class="even"><span>item10</span><span>item2</span><span>item2</span></li>
            <li class="odd"><span>item11</span><span>item3</span><span>item3</span></li>
            <li class="even"><span>item12</span><span>item2</span><span>item2</span></li>
            <li class="odd"><span>item13</span><span>item3</span><span>item3</span></li>
            <li class="even"><span>item14</span><span>item2</span><span>item2</span></li>
            <li class="odd"><span>item15</span><span>item3</span><span>item3</span></li>
            <li class="even"><span>item16</span><span>item2</span><span>item2</span></li>
        </ul>
    </div>
</div>

Finally, the key part, the js part

How to clear the timer when the mouse moves over

$(function(){
    // Clear the timer when the mouse moves over $(".slide-list").hover(function(){
        clearInterval(scrollTimer);
    },function(){
        scrollTimer = setInterval(function (){
            autoScroll(".slide-list")
        },2000);
    });
 
 
    function autoScroll(obj){
            var tableUl = $(obj);
            var first = tableUl.find('li:first');
            var height = first.height();
            first.animate({
                height:0
            },500,function(){
                first.css('height',height).appendTo(tableUl);
            })
    }
   var scrollTimer = setInterval(function(){
        autoScroll(".slide-list")
    },2000)
})

2. The timer is not cleared when the mouse moves over

$(function(){
    
    
    function autoScroll(obj){
            var tableUl = $(obj);
            var first = tableUl.find('li:first');
            var height = first.height();
            first.animate({
                height:0
            },500,function(){
                first.css('height',height).appendTo(tableUl);
            })
    }
   setInterval(function(){
        autoScroll(".slide-list")
    },2000)
})

The effect achieved:

I stepped on a pit when calling the interface polling. If you change to an interface call, you must remember to add a judgment on whether there is a timer.

if(timer != null) {
    clearInterval(timer);
}

The complete code is as follows

$(function(){
 
 
var allUrl = "http://localhost:8899/tv/alldata";
 
renderPage();
 
 var timer = setInterval(function(){
    renderPage ()
},5000);
if(timer != null) {
    clearInterval(timer);
}
 
 
function renderPage () {
    console.log(111);
    $.ajax({
        url:allUrl,
        async:true,
        success:function(result){
          console.log(result);
          if(result.success === true){
              console.log('data',result.data);
              var niujuOneData = result.data.counts[0].tvmTvToolUsageCount;
              var niujuTwoData = result.data.counts[1].tvmTvToolUsageCount;
              var niujuThreeData = result.data.counts[2].tvmTvToolUsageCount;
              var niujuFourData = result.data.counts[3].tvmTvToolUsageCount;
              var recordTableData = result.data.history;
              var useTableOneData = result.data.usage.needCheckTools;
              var useTableTwoData = result.data.usage.expireCheckTools;
              var useTableThreeData = result.data.usage.usingTools;
              console.log('data 1',niujuOneData)
 
              renderNiuju('#banshouOne','#otherOne','#totalOne',niujuOneData);
              renderNiuju('#banshouTwo','#otherTwo','#totalTwo',niujuTwoData);
              renderNiuju('#banshouThree','#otherThree','#totalThree',niujuThreeData);
              renderNiuju('#banshouFour','#otherFour','#totalFour',niujuFourData);
              renderRecordTable('#tvTableFour',recordTableData);
              renderUseStateTable ('#tvTableOne',useTableOneData);
              renderUseStateTable ('#tvTableTwo',useTableTwoData);
              renderUseStateTable('#tvTableThree',useTableThreeData);
          }
        }
    });
};
