javascript编码错误，我该如何解决它

Question

window.onload=init;

function init(){
  var passwordPrompt = prompt("What is the password?");
  var passwordPrompt2 = prompt("Im sorry that was incorrect, please try again");
  if(passwordPrompt!="1234"){
    passwordPrompt2;
  }
if(passwordPrompt2!="1234"){
    passwordPrompt2
}
}
*This code is linked to an html doc*

当我输入“1234”时，它表示不正确，一旦进入prompt2，无论您输入什么，它都会接受并转到网页而不是再次运行

Answer 1

在您测试用户提供的输入之前，您会立即第二次提示输入密码。

看起来你正试图做这样的事情：

function init(){
  var passwordPrompt = prompt("What is the password?");
  while(passwordPrompt!="1234") {
     passwordPrompt = prompt("Im sorry that was incorrect, please try again");
  }
}

Answer 2

您正在一个接一个地执行创建问题的提示。

试试这样：

function init(){
  var passwordPrompt = prompt("What is the password?");
  while(passwordPrompt!="1234") {
     passwordPrompt = prompt("Im sorry that was incorrect, please try again");
  }
}
