Move div to certain table cell according to random number

本问题已经有最佳答案，请猛点这里访问。

我是javascript新手。我正在尝试尽可能多地使用本地的javascript代码制作蛇和梯子游戏。我的问题是，我不能根据按骰子图像时产生的随机数将玩家从初始位置移动。有人能帮我移动球员吗？enter image description here

因为没能完成比赛，我很难过。我真的需要帮助。事先谢谢。

好吧，首先这个问题已经在so上被问过和回答过了，表单元格和通常的元素一样：)

因为您无论如何都在使用jquery，所以可以使用.detach()。

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

这是一个JSFIDLE。

或者，如本文所建议的，您可以使用本机JS解决方案。
