</html>我如何使用 AJAX 验证每个(上方的文本框)以查看用户名和密码是否正确，如果不正确，则在每个文本框下方以红色显示错误消息。这是我的代码。任何建议都会有所帮助。我知道我可以使用 $.ajax() 方法，但我不知道如何将当前的验证函数转换为合理的 ajax 方法。
最佳答案
$(".selector").validate({
rules: yourRules,
messages: {
username: {
remote: "Username already exists"
}
}
})
// This is cited from Stack Overflow. Would this how Ajax work internally?
