从多维数组中获取多个最大键与值的数组

function findMaxValues(arr) {
    let maxValues = [];
    let maxValue = -Infinity;

    for (let i = 0; i < arr.length; i++) {
        for (let j = 0; j < arr[i].length; j++) {
            if (arr[i][j] > maxValue) {
                maxValue = arr[i][j];
                maxValues = [{ key: [i, j], value: maxValue }];
            } else if (arr[i][j] === maxValue) {
                maxValues.push({ key: [i, j], value: maxValue });
            }
        }
    }

    return maxValues;
}

// 示例使用
const multiDimArray = [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9]
];

console.log(findMaxValues(multiDimArray));
