十幾年沒碰過網頁了最近要改一個網頁但是它是用vue寫的我完全沒用過
我想做的功能是自動填入帳號密碼然後登入
於是我寫了

document.getElementById('username').value="aaa";
document.getElementById('password').value="bbb";

可以看到帳號密碼被填入對應欄位然後我再寫

document.getElementsByTagName('button')[1].click();

用script去按下Login按紐沒想到顯示field required 帳號密碼被清空
如果我改成用手動去按登入按紐會變成密碼欄位被清空還是無法登入
但是我用script填入的帳號密碼是對的
我自己手動去填帳密登入會成功

不知是否有人遇過類似的問題? 謝謝

let el = document.getElementById("username");
el.value = val;
el.dispatchEvent(new Event('input'));

最佳解答

手動可以，js卻不行，怎麼想都是js問題XD

可能可以

F12開發人員模式於js下中斷點，看一下有沒有正確跑
確定js這抓法沒問題? 要不改別種寫法試試

document.getElementsByTagName('button')[1].click();

更:

我打到一半你剛好解決了，回答刪不掉XD
