Vue中input被赋值后,无法再修改编辑的问题及解决

 <el-form ref="formInline" :inline="true" :rules="rules" :model="formInline" label-position="right" size="medium">
	<el-form-item label="SIM卡号" prop="icsim">
        <el-input v-model.number="formInline.icsim" maxlength="18" />
    </el-form-item>
    <el-form-item label="ICCID码" prop="iccid">
        <el-input v-model="formInline.iccid" />
    </el-form-item>
    <el-form-item label="激活时间" prop="start">
        <el-date-picker v-model="formInline.start" value-format="yyyy-MM-dd HH:mm:ss" style="width:200px" placeholder="选择日期"/>
    </el-form-item>
    <el-form-item label="服务到期时间" prop="end">
        <el-date-picker v-model="formInline.end" value-format="yyyy-MM-dd HH:mm:ss" style="width:200px" placeholder="选择日期"/>
    </el-form-item>
</el-form>

export default {
  name: 'formInline',
  data () {
    return {
      formInline: {}
    }
  },
  methods: {
    // vue 请求数据
	async getSimData(params) {
      const res = await simInfoByVid(params)
      const { sid, iccid, start, end, storage, icsim, vid } = res.data
      this.formInline.sid = sid
      this.formInline.iccid = iccid
      this.formInline.start = start
      this.formInline.end = end
      this.formInline.storage = storage
      this.formInline.icsim = icsim
      this.formInline.vid = vid
    }
  }
}

data () {
    return {
      formInline: {
      	sid: '',
      	iccid: '', 
      	start: '', 
      	end: '', 
      	storage: '', 
      	icsim: '', 
      	vid: ''
		}
    }

async getSimData(params) {
      const res = await simInfoByVid(params)
      const { sid, iccid, start, end, storage, icsim, vid } = res.data
      this.$set(this.formInline, 'sid', sid)
      this.$set(this.formInline, 'iccid', iccid)
      this.$set(this.formInline, 'start', start)
      this.$set(this.formInline, 'end', end)
      this.$set(this.formInline, 'storage', storage)
      this.$set(this.formInline, 'icsim', icsim)
    }

<el-textarea
                  v-model="drawerForm.msg"
                  placeholder="请输入功能描述"
                  :rows="3"
                  allowClear
                ></el-textarea>

export default {
  name: 'drawerForm',
  data () {
    return {
      drawerForm: {}
    }
  },
  methods: {
    handleEditHelloForm () {
        // 模拟编辑功能需要数据回显
        this.helloForm.msg = 'hello 我是drawerForm中的msg值'
    }
  }
}

  data () {
    return {
      drawerForm: {
         msg：""
      }
    }
  },

data为要修改的对象，property为要添加的属性，value就是这个属性的值    handleEditHelloForm () {
        // 模拟编辑功能需要数据回显
        Vue.set(this.helloForm,'msg', 'hello 我是drawerForm中的msg')
    }
