javascript - 将div附加到td

我在做蛇和梯子游戏。我想将player1附加到板子的第一个单元中，但是它没有按我预期的那样工作。我需要如何解决的帮助。 javascript - 将div附加到td-LMLPHP

这是我使用的代码

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());
        cells[i].firstChild.nodeValue = cellNumber;
        rowCounter++;
      }
    }
    var lastRow = rows[0].getElementsByTagName('td');
    lastRow[0].id = 'lastCell';
    var firstRow = rows[9].getElementsByTagName('td');
    firstRow[0].id = 'firstCell';
    return gameBoard;
  }
};

window.onload = (function(e) {
  gameBoard.createBoard(10, "#grid");
});

提前致谢。

最佳答案

我会在这里建议2处更改:

  • 调用move()中的window.onload函数，因为在load之后创建了您的木板，而DOM在创建后获得了element #firstCell。
  • 应该是element-#player1而不是string-#player1。因此，只需将"#player1"包装在$()中，例如-$("#firstCell").append($("#player1"));

    • 更新代码

    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());
        cells[i].firstChild.nodeValue = cellNumber;
        rowCounter++;
      }
    }
    var lastRow = rows[0].getElementsByTagName('td');
    lastRow[0].id = 'lastCell';
    var firstRow = rows[9].getElementsByTagName('td');
    firstRow[0].id = 'firstCell';
    return gameBoard;
  }
};
