老师好，您好，我在用vue+elementUI制作表单时，需要为    表单中input输入框，select选择器     设置默认值，没能实现。

如下图所示，

代码如下：

      <el-row>

        <el-col :span="12">

          <el-form-item label="报告编号长度">

            <el-input v-model="info.reportcodeLength"></el-input>

          </el-form-item>

        </el-col>

        <el-col :span="12">

          <el-form-item label="起始序号">

            <el-input v-model="info.startNum"></el-input>

          </el-form-item>

        </el-col>

      </el-row>

      <el-row>

        <el-col :span="12">

          <el-form-item label="是否自动编号">

             <el-select v-model="info.autoEncode">

              <el-option label="否" value="0"></el-option>

              <el-option label="是" value="1"></el-option>

            </el-select>

          </el-form-item>

        </el-col>

        <el-col :span="12">

          <el-form-item label="是否允许无设备直接起草">

             <el-select v-model="info.isNoEquEdit" placeholder="请选择">

              <el-option label="否" value="0"></el-option>

              <el-option label="是" value="1"></el-option>

            </el-select>

          </el-form-item>

        </el-col>

      </el-row>

对应的data里设置了

      reportcodeLength: '2',

        startNum: '1',

        autoEncode: '1',
