[英]How can I pre-populate my input with data from API?
我有一個編輯表單，我正在嘗試根據 API 的響應填充我的輸入。 我的廣告系列數據如下所示。
{
"id": 219,
"name": "finishedddd-1642606412049"
}
測試
你看我可以像這樣訪問campaign.name
<p>Campaign Name : {{ campaign.name }}</p>
試
我想預先填寫我的姓名輸入，所以我這樣做了
data() {
return {
campaign: {},
form: {
errors: {},
values: {
name: this.campaign.name,
...
結果
不知何故，這一直讓我：
“TypeError：無法讀取未定義的屬性（讀取'名稱'）”

您基本上是在嘗試訪問尚未定義的變量。 data() 僅在初始化組件時調用一次。 這發生在您從 api 獲得響應並將值分配給 this.campaign 之前。
這就是為什么這條線不起作用：
name: this.campaign.name
你可以做的是這樣的：
data() {
return {
campaign: {},
form: {
errors: {},
values: {
name: "",
...
getCampaign() {
...
axios.post(`${process.env.VUE_APP_API_ENDPOINT_URL}`, body)
.then((response) => {
if (response.data.status == 0) {
this.campaign = response.data.campaigns[0]
this.form.values.name = this.campaign.name
...
牢記您的要求，您可以使用watch屬性使兩個值保持同步
將初始form.values.name設置為''
data() {
return {
campaign: {},
form: {
errors: {},
values: {
name: '',
...
並保持值同步，您可以執行以下操作：
watch: {
campaign: {
handler(newVal) {
this.form.values.name = newVal.name
},
immediate: true
}
}
嘗試
<p>Campaign Name: {{ campaign?.name }}</p>
