Question

我在学校有一个制作数独游戏的项目，当尝试从数组中应用随机数独出现在html中时遇到问题当我使用一个非随机数独时，它工作正常，但是当我使用randomSudoku作为矩阵时，它全部弄乱了，并在每个输入中给了我整个数组

//this is the 9x9 matrix and there are 3 more
let sudoku1 = [
    [8, 2, 7, 1, 5, 4, 3, 9, 6],
    [9, 6, 5, 3, 2, 7, 1, 4, 8],
    [3, 4, 1, 6, 8, 9, 7, 5, 2],
    [5, 9, 3, 4, 6, 8, 2, 7, 1],
    [4, 7, 2, 5, 1, 3, 6, 8, 9],
    [6, 1, 8, 9, 7, 2, 4, 3, 5],
    [7, 8, 6, 2, 3, 5, 9, 1, 4],
    [1, 5, 4, 7, 9, 6, 8, 2, 3],
    [2, 3, 9, 8, 4, 1, 5, 6, 7]];
//these are the array of sudokus(each sudoku is a 9x9 matrix)
let allSudokus = [[sudoku1], [sudoku2], [sudoku3], [sudoku4]]
let randomSudoku = allSudokus[Math.floor(Math.random() * allSudokus.length)]

//this is the function i did in order to fill "solve" the board
const solveBoard = () => {
    for (let r = 0; r < 9; r++) {
        for (let c = 0; c < 9; c++) {
            let cellid = document.querySelector("#r" + r + "c" + c); //
            cellid.innerHTML = randomSudoku[r][c]
        }
    }
}

this is what happens when i use randomSudoku

this is when i use sudoku1

Answer 1

您正在使用allsudokus（不存在）而不是allSudokus。这样做：

let randomSudoku = allSudokus[Math.floor(Math.random() * allSudokus.length)]

，然后在这里相同：

cellid.innerHTML = randomSudoku[r][c]

编辑：确定，您现在已解决该问题
