我在谷歌上浏览了关于 SO 和文档的各种问题。我发现 jquery post 发生在按钮/链接单击或表单提交事件上。

我正在使用 facebook JS sdk。我在我的页面上保留了 facebook 登录按钮。如果是第一次在现场使用,用户登录时会出现按钮,用户喜欢的电影将存储在数据库中,然后使用 ajax 重定向到新页面。

以前我编写了用户单击按钮时执行操作的位置。

现在我希望它自动检查登录状态(发生这种情况),将数据发布到 x.php(此页面将插入到数据库中),然后重定向到新页面 y.php。

$( "a" ).click(function( event )我不知道没有or怎么办submit

如果有人可以提供帮助,我已经在这里编码:
