实现el-table点击任意位置选中当前行并设置默认值

不念不忘少年蓝@ 2023-01-08 02:26 1112阅读 0赞

这个需求，先是其他同事在做。在他的基础上我来改。思路比较混乱。浪费了一天半才解决。

需求：

点击，左边勾选之后。右边的输入框内的值变成30（只针对当前行生效）默认不填的话。值是null

然后我还加了个功能，在点击右边编辑的时候。就选择当前这行。

关键代码：

列表

<el-dialog customClass="customWidth" title="接口授权" :visible.sync="openPower">
          <el-table v-loading="loading" :data="interfaceOptions" @selection-change="handleInterfaceSelectionChange"
                    @select="handleSelectRow" ref="interfaceTable" @row-click="handleRow"
          >
            <el-table-column type="selection" width="55" align="center"/>
            <el-table-column label="名称" align="center" prop="name"/>
            <el-table-column label="并发数" align="center" prop="count">
              <template slot-scope="scope">
                <el-input
                  placeholder="默认值:30"
                  v-model="scope.row.count"
                  @change="getCountData(scope.row)"
                  style="width: 25%;text-align: center;"
                >
                </el-input>
              </template>
            </el-table-column>
          </el-table>
        
          <div slot="footer" class="dialog-footer">
            <el-button type="primary" @click="submitInterface">确 定</el-button>
            <el-button @click="cancelInterface">取 消</el-button>
          </div>
        </el-dialog>

data参考下面的完整代码

方法：

handleInterfaceSelectionChange(selection) {
          console.log(selection)
          this.newOptions = selection
          this.intSingle = selection.length === 1
          this.intMultiple = selection.length > 1
    
        },
        handleSelectRow(selection, row) {
          console.log(selection)
          this.newSelection = selection
          if (row.count === null) {
            row.count = 30
          }
        },
      handleRow(row) {
          // console.log(row)
          // console.log(row.count)
          if (row.count === null) {
            row.count = 30
          }
          const selection = this.$refs.interfaceTable.selection
          const idArr = selection.map(item => item.__ob__.dep.id)
          const idIndex = idArr.indexOf(row.__ob__.dep.id)
          if (idIndex < 0) {
            this.$refs.interfaceTable.selection.push(row)
          } else {
            // selection.splice(idIndex,1)//点击去掉当前行
          }
          console.log(selection)
          console.log(this.$refs.interfaceTable.selection)
    
          this.newOptions = selection
    
        },

el-table的row-click时间会返回row，  
再调用table内部的toggleRowSelection方法可实现

el-table 本身选中某行就会有选中样式，row-click会返回当前行数据
