在 Rails 中使用 jQuery 进行 Ajax 请求

发布于 2024-09-03 18:57:51 字数 1050 浏览 3 评论 0原文

我正在使用 jQuery 发送 Ajax 请求。发生的情况是我收到“405 方法不允许”错误。我只是发布一个表单，它将从表单中获取详细信息并将其插入数据库中。只是平常的东西。我使用的是 Rails 包默认附带的 WEBrick。有人可以告诉我如何解决这个问题吗？

这是触发 Ajax 请求的代码

$.post($(this).attr("action") + ".js",$(this).serialize(),null,"script");

I am sending an Ajax Request using jQuery. What happens is that I am getting an "405 Method Not Allowed" Error. I am just posting a form, which would get the detail from the form and insert it into the DB. Just the usual stuff.I am using WEBrick that comes as default with the rails package. Can somebody please tell me how to fix this.

This is the code that triggers the Ajax Request

$.post($(this).attr("action") + ".js",$(this).serialize(),null,"script");

我才知道这是同源策略错误。
jQuery $.ajax(), $.post 发送“OPTIONS”作为 Firefox 中的 REQUEST_METHOD

为什么使用非静态 URL 来创建评论？是否可以使用rest提供的正常创建操作？我真的推荐它，它让思考变得更容易。

如果你能做到这一点，这个 form_for 方法应该可以解决问题：

<% form_for Comment.new do |f| %>

Why are you using a non-restful url to create a comment? Is it possible to use the normal Create action provided by rest? I really recommend and it makes the thinks easier.

If you can do this, this form_for method should do the trick:
