嵌套的JavaScript函数，或者While（）循环

我知道关于这个话题已经有两个问题发布了，但它们并没有真正回答我的问题（或者是因为我只是一个低水平的程序员）。我的问题是，我正在尝试通过实践来学习java（并且失败了很多次），所以我正在尝试制作一个游戏。我输入了大量的代码，它开始看起来很糟糕，所以我想oO（为什么不嵌套一些while（）语句，这样可以压缩代码！）。。。它不起作用，我不明白为什么

    $(document).ready(function() {

        $("#console").fadeIn(3000); //A console to keep everything good

        $("form").submit(function() { //User input
            var input = $("#command_line").val(); //A nifty box to put your answers in
            var check = false;
            function check() { //If you don't follow directions this happens
                check = true;
            };
        //startup
        function start() { //This function is nested, and runs
            var yes = false; //defining yes
            var no = false; //defining no
            while (yes == false && no == false && currentarea == "startup") { //<-- This while loop does nothing?
                if (input == "yes") {
                    yes = true; //changing yes to true
                    $("<p>Great! What is your gender? Type <u><b>m</b></u> for Male or <u><b>f</b></u> for Female.</p>").hide().insertBefore("#placeholder").fadeIn(1000);
                    check();
                }
                else if (input == "no") {
                    no = true; //changing no to true
                    $("<p>Sorry to see you go. Press F5 to restart, or exit your browser.</p>").hide().insertBefore("#placeholder").fadeIn(1000);
                    check();
                }
                else if (yes == true || no == true) {   
                    $("<p>You've already answered this question.</p>").hide().insertBefore("#placeholder").fadeIn(1000);
                    check();
                }
            }   
        };

$（文档）.ready（函数（）{
$（“#控制台”）.fadeIn（3000）；//保持一切正常的控制台
$（“表单”）.submit（函数（）{//用户输入
var input=$（“#命令行”）.val（）；//一个漂亮的框，可以把答案放进去
var检查=假；
函数检查（）
检查=正确；
};
//启动
函数start（）{//此函数嵌套并运行
var yes=false；//定义yes
var no=false；//定义no
而（yes==false&&no==false&¤tarea==“startup”）{/正如@Ankur所指出的，您从未调用
start
函数

您可以这样做：

  $(document).ready(function() {
      $("#console").fadeIn(3000); //A console to keep everything good

      $("form").submit(function() { //User input
          var input = $("#command_line").val(); //A nifty box to put your answers in
          var check = false;

          function check() { //If you don't follow directions this happens
              check = true;
          };
          //startup
          function start() { //This function is nested, and runs
              var yes = false; //defining yes
              var no = false; //defining no
              while (yes == false && no == false && currentarea == "startup") { //<-- This while loop does nothing?
                  if (input == "yes") {
                      yes = true; //changing yes to true
                      $("<p>Great! What is your gender? Type <u><b>m</b></u> for Male or <u><b>f</b></u> for Female.</p>").hide().insertBefore("#placeholder").fadeIn(1000);
                      check();
                  } else if (input == "no") {
                      no = true; //changing no to true
                      $("<p>Sorry to see you go. Press F5 to restart, or exit your browser.</p>").hide().insertBefore("#placeholder").fadeIn(1000);
                      check();
                  } else if (yes == true || no == true) {
                      $("<p>You've already answered this question.</p>").hide().insertBefore("#placeholder").fadeIn(1000);
                      check();
                  }
              }
          };
          start();
      });
  });

start
函数。@Manos Kounelakis-很抱歉。我太新了，不知道两者之间的区别。我应该在挂上标签之前进行调查。@Ankur-我明白了。我甚至没有正确地执行循环。所以，我真的浪费了您的时间……很抱歉t、 谢谢。它允许循环执行我想要的操作。对于第二部分，“也不要在事件中声明新函数（如表单提交）。在代码顶部声明它”我在关注YouTube视频。这也是我的代码非常长的原因。
