又再想問下react/js問題，搞左好耐
話說依家我有條array，每一個elements都會render一個input
類似咁，[ ]係個input, x係一個取消制
1. [ A ] x
2. [ C ] x
3. [ D ] x
4. [ E ] x
以上就係一條length係4既array所render出黎既4條input
我想做到例如禁左個x，個一個對應既input就會消失，即係個array會remove左個個element
例如我係input有C個個禁X，我理想係會變成咁：
1. [ A ] x
2. [ D ] x
3. [ E ] x
但我依家佢變左無論我係禁邊一個X制，佢都係會由最後個個element開始delete，即係就算我禁A個個input既X，會remove既都係E...再禁一次係remove D...禁到最後先會remove A
我既code係咁:
const [inputBox, setInputBox] = useState([]);
const deleteInputHandler = (index) => {
．．setInputBox([
．．．...inputBox.slice(0, index),
．．．...inputBox.slice(index + 1, inputBox.length)
．．]);
}
都幾肯定index係冇錯，係真係個個input對應既array element既index
想問下我係邊度錯左?
我知道好似filter係做到同樣既野，但我用filter一樣係唔得
const deleteInputHandler = (index) => {
．．setInputBox((prev) => prev.filter((data, inputIndex) => inputIndex !== index));
}
個結果係一樣
==============
如果我試
const deleteInputHandler = (index) => {
．．setInputBox((prev) => [
．．．...prev.slice(0, index)
．．]);
}
佢又識得將個個index既input同打後既array elements全部刪除哂
即係係岩，但係想加返delete個input對下既個d array就出問題

1 year
const deleteInputHandler = (index: number) => {
setInputBox((prev) => [...prev].filter((_, i) => index !== i));
};都係唔得，個結果都係由尾開始減
定係根本個問題唔係係依個function度
而係其他野郁左個array?
