大家好，

我正在尝试使用此ajax方法来验证上方框的输入文本字段，但我怎样才能使其工作？
我做错了什么？

我希望它的工作方式是，如果用户输入了错误的用户名和密码，它会显示错误消息，并且不会将旧内容设置为左侧的动画。
我该如何修复我的ajax方法？

Answer 1

只是为了解决这个问题......

在我们拥有nice chat discussion之后，您了解到Ajax对于实现您的期望并不是很有用。你得到了它有用的东西。

因此，您无需使用Ajax 来验证一个或多个文本框。。相反，使用jQuery Validate plugin（或其他一些插件......有很多！Google“JavaScript验证”）

很好的答案我建议你看一下this one，很多用户同意这个事实是«比实际文档要好得多»

我认为这个插件是最常用的...至少是最知名的。

我还建议你阅读https://en.wikipedia.org/wiki/Regular_expression，这是一种有效查找字符串部分的方法......它可以与上面的验证插件一起使用。

总而言之，这个super usefull tool来测试正则表达式是必须的。
