vue table大屏自動刷新滾動效果

1.實現效果

2.步驟原理

1.樣式：thead頭部固定，tbody滾動，動態給tbody加動畫效果

2.數據：計時器更改數據變化，每次數組尾部添加第一個元素 this.tableData.push(this.tableData[0])，再去除第一個元素 this.tableData.shift()

3.判斷刷新數據: this.tableData[0].id === this.endId 滾動的數組第一個元素等於原始數組最后一個時，請求后台刷新數據，清清除計時器

3.具體實現步驟

1.table結構

<div class="box2">
        <table border="1" class="table_main">
          <thead>
            <tr>
              <th class="coll1">工單號</th>
              <th class="coll2">是否緊急</th>
              <th class="coll3">工單狀態</th>
              <th class="coll4">報修科室</th>
              <th class="coll5">維修事項</th>
              <th class="coll6">維修地點</th>
              <th class="coll7">備注</th>
              <th class="coll8">派工時間</th>
              <th class="coll9">處理人</th>
            </tr>
          </thead>
          <thead class="zindex">
            <tr>
              <th class="coll1">工單號</th>
              <th class="coll2">是否緊急</th>
              <th class="coll3">工單狀態</th>
              <th class="coll4">報修科室</th>
              <th class="coll5">維修事項</th>
              <th class="coll6">維修地點</th>
              <th class="coll7">備注</th>
              <th class="coll8">派工時間</th>
              <th class="coll9">處理人</th>
            </tr>
          </thead>
          <tbody :class="{anim:animate==true, hei: isLenght===true}">
            <tr v-for="(item, index) in tableData" :key="index" :class="{red: item.gdStatusName==='待受理', yellow: item.gdStatusName==='待接收'}">
              <td class="coll1" :title="item.code">{{ item.code }}</td>
              <td class="coll2" :title="item.isUrgentName">{{ item.isUrgentName }}</td>
              <td class="coll3" :title="item.gdStatusName">{{ item.gdStatusName }}</td>
              <td class="coll4" :title="item.deptName">{{ item.deptName }}</td>
              <td class="coll5" :title="item.items">{{ item.items }}</td>
              <td class="coll6" :title="item.palce">{{ item.palce }}</td>
              <td class="coll7" :title="item.remarks">{{ item.remarks }}</td>
              <td class="coll8" :title="item.distributeTime">{{ item.distributeTime }}</td>
              <td class="coll9" :title="item.userName">{{ item.userName }}</td>
            </tr>
          </tbody>
        </table>
      </div>

第二個thead是頁面看到的thead，為了解決下面的滾動上去和thead重合顯示的問題

2.方法

data () {
    return {
      timer: '',
      animate: false,
      tableData: [],
      endId: '',
      isLenght: false
    }
  },

 

created () {
    this.getList()
 },

getList () {
      listGuarantee().then(res => {
        console.log('res', res)
        this.tableData = res.data
        this.endId = this.tableData[this.tableData.length - 1].id
        if (this.tableData.length > 10) {
          this.isLenght = true
          this.timer = setInterval(this.scroll, 3000)
        } else {
          this.isLenght = false
          clearInterval(this.timer)
        }
      })
    },

scroll () {
      this.animate = true
      setTimeout(() => {
        this.tableData.push(this.tableData[0])
        this.tableData.shift()
        this.animate = false
        if (this.tableData[0].id === this.endId) {
          // console.log('請求刷新數據')
          this.getList()
          clearInterval(this.timer)
        }
      }, 500)
    }
