我一直在解决这个问题到令人沮丧的程度，所以我已经回到了Stackoverflow。我非常喜欢初学者，所以请耐心等待。感谢你提前帮助。
我在我的rails应用程序中使用Datatables，并且在向数据库添加行之后，我试图让表更新。我按照rails-casts的教程，在这里找到：Rails-casts: JQuery and Ajax，来到我目前的位置。
我成功地在页面上提供了一个由点击表单替换的链接。表单成功地将数据提交到数据库，然后表单被原始链接替换（就像在rails-cast教程中一样）。我遇到的唯一问题是尝试刷新表而不刷新整个页面。
我目前没有收到任何错误。我也尝试了ajax.reload（）的Datatables方法，但是，我最终遇到了与目前类似的情况。
如果我能提供任何其他信息，请告诉我。

答案 0 :(得分：0)
没有HTML输出，这是一个猜测，但您没有停止表单的默认提交行为（即替换页面）。在preventDefault()事件的第一个参数上调用submit。
e.g。
$("#new_employee").submit(function(e){
e.preventDefault();
当您单击任何提交按钮时，这将阻止表单实际发布回服务器。
