Javascript 代码赢得'；由于字符串长度问题，无法运行

这里有一个简单的Javascript程序来接受和检查密码。它应当：

要求您输入新密码

检查密码的强度，该密码根据长度6输出弱消息或强消息

让您重新输入此密码以进入“系统”

如果密码不正确，则给出简单提示或两个随机字母

除强/弱检查器外，所有功能都正常工作。它在获取passwordEntry的长度时遇到问题，因为它显然不作为实体存在

任何想法都将不胜感激

var pass;
var main = function(){
strengthCheck((prompt("Please Choose a New Password to Begin"));
}

var strengthCheck = new function(passwordEntry){
score = 0;
// adds to the score variable depending on the length of the password
if(passwordEntry.length > 6{
score=(score+1);
}
//reads messages back stating how strong password is based on length
if(score=0){
console.log("Your Password is Weak");
}
else if(score=1){
console.log("Your Password is Strong");
}
var passContinue = prompt("Do you want to continue with this password? Yes or no?")
if(passContinue === "no" ||  passContinue === "No"{
main();
}
else{
pass = passwordEntry;
console.log("Your new password has been changed to " + pass);
passwordChecker(prompt("Thank You. Please Enter Your Password Below"));
}
}

var passwordChecker = function (attempt){
if(attempt == pass){
    console.log("Correct password. The system has logged you on");
}
    else{
    //if the password is wrong, runs the incorrectpassword() function
        console.log("Incorrect Password");
        IncorrectPass();
        }
    }
}

var IncorrectPass = function (){
var clueanswer = prompt("Do You Want A Clue");
if(clueanswer === "Yes" ||clueanswer === "yes"){    
console.log("I will give you two random letters");
// takes two random locations from the string array and reads them back
var randarray1 = Math.floor((Math.random()*7)+1);
var randarray2 = Math.floor((Math.random()*7)+1);
var randletter1 = pass[randarray1];
var randletter2 = pass[randarray2];
console.log(randletter1+" "+randletter2);
passwordChecker("Please try entering your password again");  
}
    else{
        console.log("GoodBye");
    }
}

main()

改变这个

var strengthCheck = new function(passwordEntry){

对此

var strengthCheck = function(passwordEntry){

当您使用

new

时，您并没有使用它来创建新函数。您使用它作为构造函数调用函数，构造函数将返回一个对象。（在您的案例中为空对象。）

此外，代码中还有许多语法错误。使用代码验证程序和美化程序清理代码。

这部分看起来非常错误：

if(score=0){
  console.log("Your Password is Weak");
}
else if(score=1){
  console.log("Your Password is Strong");
}

您应该使用

=

或

=

而不是用于赋值而非比较的

=

这也没有道理：

var main = function(){
  strengthCheck((prompt("Please Choose a New Password to Begin"));
}

有三个左括号，只有两个右括号。闻起来像是解析器错误。

缺失）在if（passwordEntry.length>6{？你确定这是你实际使用的代码吗？第3行还有一个额外的

）。请投票所有答案和注释！谢谢，修复了。还有一些带有额外括号的错误，这些错误现在都已修复。
