JavaScript趣题：密码验证

var lengthValid = function(pass){ return pass.length >= 6; };

var contentValid = function(pass){ var lowerNum = 0; var upperNum = 0; var numNum = 0; for(var i=0;i= 48 && code <= 57){ numNum++; } else if(code >= 65 && code <= 90){ upperNum++; } else if(code >= 97 && code <= 122){ lowerNum++; } else{ return false; } } return lowerNum && upperNum && numNum; };

function validate(password) { return lengthValid(password) && contentValid(password); }
