elementUI 表格中回显checkbox是否选中

Posted 2020-12-10 longsanshi

我是通过v-if指令来做的，我用的是

checked3，checked4在data质指定。

 <el-table :data="devicesGridData">
              <el-table-column property="name" label="选择" width="80">
             
                <template slot-scope="scope">
                  <div v-if="1==scope.row.isSelected">
                    <el-checkbox v-model="checked3"  @change="deviceBoxChange(scope.row.id)"></el-checkbox>
                  </div>
                  <div v-if="0==scope.row.isSelected">
                    <el-checkbox v-model="checked4"   @change="deviceBoxChange(scope.row.id)"></el-checkbox>
                  </div>
                </template>
              </el-table-column>
              <el-table-column property="code" label="设备编号" width="100"></el-table-column>
              <el-table-column property="name" label="设备名称" width="100"></el-table-column>
              <el-table-column property="modelType" label="设备规格"></el-table-column>
          </el-table>

下面是错误的方法！！！！！！！！！！！！

 不太明白这个是什么情况，直接指定不行，为什么，分页的时候第二页就有问题了

 <el-table :data="devicesGridData">
              <el-table-column property="name" label="选择" width="80">
             
                <template slot-scope="scope">
                  <div v-if="1==scope.row.isSelected">
                    <el-checkbox checked="true"  @change="deviceBoxChange(scope.row.id)"></el-checkbox>
                  </div>
                  <div v-if="0==scope.row.isSelected">
                    <el-checkbox checked="false"   @change="deviceBoxChange(scope.row.id)"></el-checkbox>
                  </div>
                </template>
              </el-table-column>
              <el-table-column property="code" label="设备编号" width="100"></el-table-column>
              <el-table-column property="name" label="设备名称" width="100"></el-table-column>
              <el-table-column property="modelType" label="设备规格"></el-table-column>
          </el-table>
