axios 的參數
Line 10 in dae4b75
let url="https://www.twse.com.tw/exchangeReport/STOCK_DAY?response=json&date=20210523&stockNo=2610";
你的網址這時候已經帶對參數了,所以在 axios.get
的時候就不用再送參數了,如果要用params
才傳送參數的話,網址後面就不用帶,例如:
axios.get("https://www.twse.com.tw/exchangeReport/STOCK_DAY", {
params: {
response: "json",
date: "20210523",
stockNo: "2610",
},
}).then...
resolve 資料回傳建議
通常我們比較習慣在 resolve / reject 的時候只回傳「資訊」,例如
resolve(`非同步請求成功,結果為 ${this.responseText}`)
然後在 then 裡面才會去處理拿到的資訊,例如在 then 裡決定要把資訊顯示在 message 這個 div 裡。
但這些都是看場景與設計,以上是給你參考。
onload 的 input
nodejs-mfee16/Basic-practice/index.html
Line 31 in dae4b75
onload 應該是沒有 response 這個 input,在 onload 這個 callback 就是用 this.responseText 就可以了,你可以 console.log(this) 觀察看看。
error 的型別
Line 20 in 1d4a696
這個 error 好像不是一個布林值,你有印出來看看嗎?可以故意把檔名寫壞測試。
