javascript - 如何使用Java枚举Snake and Ladder board？

我需要使用JavaScript制作Snake and Ladder游戏，但是我被困在枚举棋盘上，以使其与图像中的棋盘相同。

var board = {
  createBoard: function(dimension) {
    if (!dimension || isNaN(dimension) || !parseInt(dimension, 10)) {
      return false;
    } else {
      dimension = typeof dimension === 'string' ? parseInt(dimension, 10) : dimension;
      var table = document.createElement('table'),

我需要这方面的帮助。提前致谢。

最佳答案

使用您的代码，我将执行以下操作：



var board = {
  createBoard: function(dimension) {
    if (!dimension || isNaN(dimension) || !parseInt(dimension, 10)) {
      return false;
    } else {
      dimension = typeof dimension === 'string' ? parseInt(dimension, 10) : dimension;
      var table = document.createElement('table'),
        tbody = document.createElement('tbody'),
        row = document.createElement('tr'),
        cell = document.createElement('td'),
        rowClone,
        cellClone;
      table.appendChild(tbody);
      for (var r = 0; r < dimension; r++) {
        rowClone = row.cloneNode(true);
        tbody.appendChild(rowClone);
        for (var c = 0; c < dimension; c++) {
          cellClone = cell.cloneNode(true);
          rowClone.appendChild(cellClone);
        }
      }
      document.body.appendChild(table);
      board.enumerateBoard(table);
    }
  },
  enumerateBoard: function() {
    var rows = document.getElementsByTagName('tr'),
      text = document.createTextNode(''),
      rowCounter,
      size = rows.length,
      len,
      cells,
      odd = false,
      count = 0,

        if (odd === true){
