Question

我是JavaScript新手。我正在尝试尽可能使用原生JavaScript代码制作Snakes and Ladders游戏。我的问题是我无法根据按下骰子图像时产生的随机数将玩家从初始位置移开。任何人都可以帮助我如何移动球员吗？

var gameBoard = {
  createBoard: function(dimension, mount, intialPosition) {
    var mount = document.querySelector(mount);

    } else {

      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++) {

我对无法完成比赛感到悲惨。我真的需要帮助。提前致谢。

嗯，首先这个问题已经在SO asked and answered上了，表格单元格和普通元素一样：）

由于您仍在使用jQuery，因此您可以使用.detach()

var element = $('td:eq(0) span').detach();
$('td:eq(1)').append(element);

这里是jsfiddle。

或者，正如this answer中提议的那样，您可以使用native js solution。

根据随机数
