我创建了一个新的数组作为stockModeOptions来保存更新的数组数据。我写了02个条件来检查它是null还是空字符串。
并且在“OD.splice（OD.长度-2，2）”中也有一个打印错误;我也分析了错误的数据。
而且我每次更新这个useEffect的时候，整个状态也会更新

useEffect(() => {
        let od = [...options?.stockModeList]

        if (state?.parentVariant === '' || state?.parentVariant === null){
            od.splice(od.length - 2, 2);
        } else {
            od.splice(0, 3);
        }

        setOptions((state) =>({
            ...state,
            stockModeOptions : od,
        }))

    }, [state])

import React, { useState } from 'react';

function MyComponent() {
  const [items, setItems] = useState([{
    "label": "One",
    "value": "one"
}, {
    "label": "One",
    "value": "two"
}, {
    "label": "One",
    "value": "three"
},]); // your arrays item

  const handleValueChange = (index, newValue) => {
    // Create a new array with the updated value
    const updatedItems = [...items];
    updatedItems[index] = newValue;

    // Update the state with the new array
    setItems(updatedItems);
  };

  const handleRemoveItem = (index) => {
    // Create a new array without the item to be removed
    const updatedItems = items.filter((_, i) => i !== index);

    // Update the state with the new array
    setItems(updatedItems);
  };

  return (
    <div>
      {items.map((item, index) => (
        <div key={index}>
          <input
            type="text"
            value={item}
            onChange={(e) => handleValueChange(index, e.target.value)}
          />
          <button onClick={() => handleRemoveItem(index)}>Remove</button>
        </div>
      ))}
    </div>
  );
}

export default MyComponent;
