js评估密码强度
js实现评估密码的强度

检验密码强度的JS类
<script type="text/javascript">        var PasswordStrength ={            Level : ["高，实在是高","还行啦","靠，这样也行"],            LevelValue : [30,20,0],//强度值            Factor : [1,2,5],//字符加数,分别为字母，数字，其它            KindFactor : [0,0,10,20],//密码含几种组成的加数            Regex : [/[a-zA-Z]/g,/\d/g,/[^a-zA-Z0-9]/g] //字符正则数字正则其它正则            }        PasswordStrength.StrengthValue = function(pwd)        {            var strengthValue = 0;            var ComposedKind = 0;            for(var i = 0 ; i < this.Regex.length;i++)            {                var chars = pwd.match(this.Regex[i]);                if(chars != null)                {                    strengthValue += chars.length * this.Factor[i];                    ComposedKind ++;                }            }            strengthValue += this.KindFactor[ComposedKind];            return strengthValue;        }        PasswordStrength.StrengthLevel = function(pwd)        {            var value = this.StrengthValue(pwd);            for(var i = 0 ; i < this.LevelValue.length ; i ++)            {                if(value >= this.LevelValue[i] )                    return this.Level[i];            }        }              alert(PasswordStrength.StrengthLevel("23"));        alert(PasswordStrength.StrengthLevel("abcd123"));            alert(PasswordStrength.StrengthLevel("abcd!%23"));     </script>
