设计一个弹框，右击某行弹出且有初始值？

Question

弹窗：

    <el-dialog
      class="editForm"
      title="编辑"
      :visible.sync="dialogFormVisible"
      @open="openDialog"
      @close="resetForm"
    >
      <el-form
        :inline="true"
        :model="editForm"
        :rules="editFormRules"
        ref="ruleForm"
        label-width="140px"
        label-position="left"
      >
        <template
          v-for="(item, index) in cols.filter(
            (item) => item.prop !== 'usestate' && item.prop !== 'recordtime'
          )"
        >
          <!-- 不需要参与循环的字段有 usestate,recordtime -->
          <!-- 在循环时需要额外做显示处理的由 shiftplancount,desc -->
          <el-form-item :label="item.label" :prop="item.prop" :key="index">
            <template
              v-if="item.prop !== 'shiftplancount' && item.prop !== 'desc'"
            >
              <el-input v-model="editForm[item.prop]"></el-input>
            </template>
            <template v-else-if="item.prop === 'shiftplancount'">
              <el-select v-model="editForm.shiftplancount" placeholder="请选择">
                <el-option label="111" value="s1"></el-option>
              </el-select>
            </template>
          </el-form-item>
        </template>
        <el-form-item label="备注" style="display: block" prop="desc">
          <el-input type="textarea" v-model="editForm.desc"></el-input>
        </el-form-item>
      </el-form>
      <div slot="footer" class="dialog-footer">
        <el-button @click="dialogFormVisible = false">取 消</el-button>
        <el-button type="primary" @click="submitEditForm(editForm)"
          >确 定</el-button
        >
      </div>
    </el-dialog>

右击鼠标，触发弹框，且将当前右击行的内容赋值给表单，作为初始值显示

  rightClick(row, column, event) {
      this.openDialog(row);
      this.dialogFormVisible = true;
      
    },
    resetForm() {
      this.$refs.ruleForm.resetFields();
    },
    openDialog(val) {
      this.editForm = val
    },

弹窗弹出后，显示内容为初始值，但是点击内容编辑报错不能对未知对象渲染。存储表单的数据已经绑定到数据节点了，后来加了$nextTickt，也不对。

用深拷贝试试：

rightClick(row, column, event) {
  this.openDialog(row);
  this.dialogFormVisible = true;
},

resetForm() {
  this.$refs.ruleForm.resetFields();
},

openDialog(val) {
  this.$nextTick(() => {
    this.editForm = JSON.parse(JSON.stringify(val)); // 用深拷贝
  });
},
