element-ui 点击行如何获取table的行索引

Posted 2020-12-03 yangyi9343

文档中有一个tableRowClassName方法，可以获取到当前行的index，

tableRowClassName ({row, rowIndex}) {
      //把每一行的索引放进row
      row.index = rowIndex;
    }　

例子：

表头：

1 <el-table :data="list" v-loading.body="listLoading" element-loading-text="Loading..."  border fit
2                   :row-class-name="tableRowClassName"
3                   @row-click = "onRowClick"
4                   highlight-current-row style="width: 100%">
5                 <el-table-column align="center" prop="passtime" label="Time" width="180">

js:

 1 tableRowClassName ({row, rowIndex}) {
 2       //把每一行的索引放进row
 3       row.index = rowIndex;
 4     },
 5     onRowClick (row, event, column) {
 6       //行点击消除new标记
 7       var index = row.index;
 8       var deleteIndex = Array.indexOf(this.showIndexArr, index);
 9       if (deleteIndex != -1) {
10         this.showIndexArr.splice(deleteIndex,1);  
11       }
12     }

以上。
