vue页面获取不到渲染
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()">

回答：
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
回答：
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
