vue页面获取不到渲染

Question

打印出来是有数据的，为什么渲染不到页面呢，

 methods: {
   init() {
       this.visible = true
       this.$nextTick(() => {
           this.$refs['dataForm'].resetFields()
           if (this.dataForm.id) {
               this.getInfo()
           }
       })
   },
    // 获取信息
    getInfo () {
      this.$http.get(`***********/${this.dataForm.id}`).then(({ data: res }) => {
        if (res.code !== 0) {
          return this.$message.error(res.msg)
        }
        this.dataForm = {
          ...this.dataForm,
          ...res.data
        }
      }).catch(() => {})
    },
    // 表单提交
                dataFormSubmitHandle: debounce(function() {
                    this.$refs['dataForm'].validate((valid) => {
                        if (!valid) {
                            return false
                        }
                        this.$http[!this.dataForm.id ? 'post' : 'put']('************', this
                            .dataForm).then(({
                            data: res
                        }) => {
                            if (res.code !== 0) {
                                return this.$message.error(res.msg)
                            }
                            this.$message({
                                message: this.$t('prompt.success'),
                                type: 'success',
                                duration: 500,
                                onClose: () => {
                                    this.visible = false
                                    this.$emit('refreshDataList')
                                }
                            })
                        }).catch(() => {})
                    })
                }, 1000, {
                    'leading': true,
                    'trailing': false
                })
            }
        }

这个是渲染页面的代码

<template>
    <el-card shadow="never" class="aui-card--fill">
        <div class="mod-fin__ney}">
            <el-form :inline="true":model="dataForm"@keyup.enter.native="getDataList()">
                <el-form-item>
                    <el-input v-model="dataForm.id" placeholder="id" clearable></el-input>
                </el-form-item>
                <el-form-item>
                    <el-button @click="getDataList()">{{ $t('query') }}</el-button>

Answer 1

dataForm所有需要渲染到页面的值都需要初始值，或者使用$set去进行设置

Answer 2

你这个应该是渲染时机的问题,初次渲染还未拿到值,你可以用v-if控制一下渲染时机,确保拿到值以后再进行渲染
