Question

我正在向文件发送ajax请求，但由于某种原因文件没有完成操作，我知道请求到达文件，因为它回应了收到的请求，并在那里停止。我无法弄清楚为什么。

Answer 1

JQuery ajax方法，数据参数除其他外需要一个对象，例如：

data: { username: username, password: password, passverif: passverif, email: email ... }

你正在通过：

data: "{username,password,passwordverif,email...}"

在那里不起作用的一些事情：1）不是key: value对，2）这是一个字符串，而不是一个对象。

另一个问题，这些：

var username = $('.username').val;

...需要更改为：

var username = $('.username').val();

注意最后的括号。

所以你要解决3件事。两个在JavaScript中，一个在PHP文件中。

JavaScript的：

在data设置中使用对象表示法。
不要引用该对象。

PHP：

使用$_POST['submit']以外的内容检查服务器脚本上的表单数据。

Answer 2

你有几个错误：

在你的AJAX调用中使用这种方式发送参数，比如bloodyKnuckles指出：

data: { username: username, password: password, passverif: passverif, email: email ... }

此外，未定义$_POST['submit']。相反，请尝试使用$_POST['username']或您参数中的其他内容。
