el-table 单项type=＂selection＂出现数据错乱解决

原先用的是@selection-change="selectionLineChangeHandle"，发现会出现数据错乱，选中下一条获取的数据还是上一条。解决方法如下：

template代码

//把下面语句
el-table @selection-change="selectionLineChangeHandle" ref="table"
//改成
el-table @select="(selection, row) => {selectionLineChangeHandle(selection, row);}" ref="table"

js代码

//选中事件
selectionLineChangeHandle(selection, val) {
  // 单选
  this.dataonLineListSelections = [];
  if (selection.length > 1) {
	this.$refs.table.clearSelection();
	this.$refs.table.toggleRowSelection(selection.pop());
  }
  if (selection.length > 0) {
	this.dataonLineListSelections.push(val);
  }
}

在列表接口中清空dataonLineListSelections
