Question

我使用Phaser框架构建了一个游戏。游戏结束时，玩家的高分记录在变量（this.inputScore）中。要将他们的高分提交到服务器，玩家单击一个按钮，将其带到Index.html页面，在该页面中将填写表单。为避免作弊，我希望从游戏的JavaScript文件中传递高分变量（Game.js），将表单上的输入值作为只读值。我已经在Game.js文件中创建了一个函数（assignValue）来执行此任务，但是由于范围的原因，我无法让Index.html文件读取该函数。当我将函数放置在Game.js脚本的顶部（全局）时，Index.html读取该函数并相应地执行该函数（但出于测试目的使用硬编码值。）如何获取Index.html文件读取我的assignValue（）函数并将this.inputScore传递给Index.html中的输入值？

Game.js文件：

  //INDEX.HTML READS THIS assignValue function AND APPLIES IT BECAUSE IT 
  //IS IN GLOBAL SCOPE. BUT I NEED THE VALUE TO BE A VARIABLE TAKEN FROM A 
  //FUNCTION INSIDE THE GAME CODE. SEE GAME CODE BELOW:

  function assignValue() {

    document.getElementById("inputScore").value = 127;

};



//GAME CODE

var CrystalRunner = CrystalRunner || {};

CrystalRunner.GameState = {

init: function() {
  //...code here
  }, 


create: function() {
 //...code here
  },  


 update: function() {  
//..code here
//check if the player needs to die
      if(this.player.top >= this.game.world.height && this.counter === 0 || this.player.left <= 0 && this.counter === 0) {
         this.gameOver();
      }
  },  


 gameOver: function(){
    this.game.time.events.stop();
    this.player.body.enable = false;
    //..code here

    this.updateHighscore();

    //..code here

   },


  updateHighscore: function(){
    this.highScore = +localStorage.getItem('highScore');


    if(this.highScore < this.myScore){
            this.highScore = this.myScore;
            this.inputScore = this.highScore;


            this.congrats = this.game.add.sprite(this.game.world.centerX-193, this.game.world.centerY-20, 'congrats');
            this.congrats.inputEnabled = true;
            this.congrats.fixedToCamera = true;

            this.submitScoreButton = this.game.add.sprite(this.game.world.centerX-135, this.game.world.centerY+100, 'submitScoreButton');
            this.submitScoreButton.inputEnabled = true;
            this.submitScoreButton.fixedToCamera = true;

            this.submitScoreButton.events.onInputUp.add(function() {

                    window.location.href = "index1.php";

              }, this);

      }


      localStorage.setItem('highScore', this.highScore);
  },

//THE FUNCTION BELOW IS NOT BEING READ BECAUSE OF SCOPE. HOW TO I MAKE INDEX.HTML READ IT?
  assignValue: function() {

                document.getElementById("inputScore").value = this.inputScore;

  },


};
