基本上在这个注册系统中我想检查是否：
所有字段都已填满。
用户名长度检查。
密码长度检查。
检查电子邮件是否有效。
检查是否未收到电子邮件。
检查是否未使用用户名。
检查密码是否等于repassword。
问题：
第一步没问题，但在我填满所有输入后，相同的错误加速，但输入周围没有2px红色边框。
如果我不填写所有内容，我会得到相同的错误+红色边框。
基本上我想调试/排除当前系统正在执行的操作，并使用超时来测试localhost是否正常工作。
有我的代码：
$("#center").on('click', function(e) {
// Prevent submit.
e.preventDefault();
/**
* Variables
**/
// Errors div block
var errors = $(".errors");
// Username input
var username = $("#username");
// Password input
var password = $("#password");
// Re-password input
var repassword = $("#repassword");
// Email input
var email = $("#email");
// Display name input
var display = $("#display");
// Validating all forms
var incomplete = $(':input', this.form).filter(function() { return $(this).val() == ''; });
// For submit, need $this var
var self = this;
/************************************/

我的职能：
function isValidEmailAddress(emailAddress) {
var pattern = new RegExp(/^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?$/i);

}
基本上，它没有进入下一步，它坚持第一步。 填写完所有输入后，它会给出错误：“其中一个字段为空。”
为什么这样做？为什么不继续？
