整理Vue项目开发过程中遇到的常见问题2

51 表格当选择项发生变化事件selection-change，翻页 搜索事件也会触发它，要改成手动事件

    // 按人员授权选中事件
    handleSelectWaitChoose (selection, row) {
      const index = this.tableData2.findIndex(item => item.id === row.id)
      if (~index) {
        this.tableData2 = this.tableData2.filter(item => item.id !== row.id)
      } else {
        this.tableData2.push(row)
      }
      this.userIds = this.tableData2.map(v => v.id)
    },
    // 按人员授权全部选中事件
    handleSelectWaitChooseAll (selection, flag) {
      if (selection && selection.length) {
        selection.forEach(item => {
          if (this.tableData2.findIndex(ele => ele.id === item.id) === -1) {
            this.tableData2.push(item)
          }
        })
      } else {
        this.tableData.forEach(item => {
          const index = this.tableData2.findIndex(ele => ele.id === item.id)
          if (index !== -1) {
            this.tableData2.splice(index, 1)
          }
        })
      }
      this.userIds = this.tableData2.map(v => v.id)
    },
