密码匹配方法验证javascript

Question

它无法正常工作，我得到密码不匹配！对于我用字母，数字和大写字母写的每个密码

var reg = /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?!.*\s).*$"/; 

var pass = document.getElementById("password").value;
if (pass == "") {
  alert("Enter the user password");
  document.getElementById("password").focus();
  return false;
}

if (pass.length < 8) {
  alert("Password too short, at least 8 characters");
  document.getElementById("password").focus();
  return false;
}
var pasw = pass.match(reg);
if (pasw) {
  alert("Password is valid");
} else {
  alert("Password doesn't match!");
  return false;
}

首先，根据此结果使用clearTimeout(timeout); timeout = setTimeout(function(){...}, 2000); 代替var reg = ^(?:(?=.*[a-z])(?:(?=.*[A-Z])(?=.*[\d\W])|(?=.*\W)(?=.*\d))|(?=.*\W)(?=.*[A-Z])(?=.*\d)).{8,}$：

Regular expression to enforce complex passwords, matching 3 out of 4 rules

其次，使用var reg = /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?!.*\s).*$"/;代替reg.test(pass)。

JavaScript test() Method

  

test（）方法测试字符串中的匹配项。   如果找到匹配项，则此方法返回true，否则返回   假的。

pass.match(reg)
