 密码强度验证的正则表达式 6个答案 
 
 
 
 
 我正在进行强度密码测试，并试图检查密码是否包含大写和小写字符。 我使用了两个正则表达式，他们几乎都在工作; 代码只是在这里： 
 
 
 
 
 
  
    var upper = false;
    var lower = false;
    var upperCase= new RegExp('[^A-Z]');
    var lowerCase= new RegExp('[^a-z]');
    


    if (password.match(upperCase )){
        upper = true;    
    }
    if (password.match(lowerCase)){
        lower = true;
    }
 
 
 
 
 
 当我输入数字或只输入一个数字时，如“1”，上下变为真。 
 
 我用正则表达式不太好，我犯了一个错误吗？

 Regular Expression for Password Strength Validation  6 answers  
 
 
 
 
I'm working on a strength password test, and I'm trying to check if the password has upper, and lower, case characters. I'm using two regular expressions, and they're almost working; with the code just here:
 
 
 
 
 
  
    var upper = false;
    var lower = false;
    var upperCase= new RegExp('[^A-Z]');
    var lowerCase= new RegExp('[^a-z]');
    


    if (password.match(upperCase )){
        upper = true;    
    }
    if (password.match(lowerCase)){
        lower = true;
    }
 
 
 
 
 
When I'm typing numbers, or just a digit, like "1", upper and lower become true. 
 
I'm not really good with regex, did I made a mistake?
