Question

我是JavaScript新手。我正在制作蛇与梯子游戏。我在代码上面临一些问题。

首先我无法存储播放器的当前位置，因此我可以计算下一个目的地。
骰子在游戏开始时以1开始，这会导致玩家从第二个单元格开始。
显示在电路板上的大蛇和梯子div不能自动适应电路板的大小。

这是我到目前为止编写的代码Snakes and Ladder Game

var gameBoard = {
  createBoard: function(dimension, mount) {
    var mount = document.querySelector(mount);
    if (!dimension || isNaN(dimension) || !parseInt(dimension, 10)) {
      return false;
    } else {
      dimension = typeof dimension === 'string' ? parseInt(dimension, 10) : dimension;
      var table = document.createElement('table'),
        row = document.createElement('tr'),
        cell = document.createElement('td'),
        rowClone,
        cellClone;
      var output;
      for (var r = 0; r < dimension; r++) {
        rowClone = row.cloneNode(true);
        table.appendChild(rowClone);
        for (var c = 0; c < dimension; c++) {
          cellClone = cell.cloneNode(true);
          rowClone.appendChild(cellClone);
        }
      }
      mount.appendChild(table);
      output = gameBoard.enumerateBoard(table);
    }
    return output;
  },
  enumerateBoard: function(board) {
    var rows = board.getElementsByTagName('tr'),
      text = document.createTextNode(''),
      rowCounter = 1,
      size = rows.length,
      cells,
      cellsLength,
      cellNumber,
      odd = false,
      control = 0;
    for (var r = size - 1; r >= 0; r--) {
      cells = rows[r].getElementsByTagName('td');
      cellsLength = cells.length;
      rows[r].className = r % 2 == 0 ? 'even' : 'odd';
      odd = ++control % 2 == 0 ? true : false;
      size = rows.length;
      for (var i = 0; i < cellsLength; i++) {
        if (odd == true) {
          cellNumber = --size + rowCounter - i;
        } else {
          cellNumber = rowCounter;
        }
        cells[i].className = i % 2 == 0 ? 'even' : 'odd';
        cells[i].id = cellNumber;
        cells[i].appendChild(text.cloneNode());

任何人都可以帮助我吗？提前致谢

Answer 1

要存储用户当前位置，请维护用于存储diff player目标的单独变量。
要从1开始播放，请删除intialPosition（）并使var w = 0，因此一旦调用rolldice（），它将从0开始。
为了根据屏幕大小的变化自动调整，请使用可以自动调整div大小的bootstrap div。这是http://getbootstrap.com/css/#grid
