javascript - 有没有办法用javascript查找字符串来自哪个txt文件？

Question

我有一个从 16 个 txt 文件中随机生成的句子，我正在尝试对该函数进行逆向工程，以便我可以看到哪个句子对应于哪个 txt 文件。我现在正在使用 if/else 但它非常慢，我想知道是否还有另一种方法可以做到这一点？我正在使用 p5.js 和 rita.js 库。

var lines, markov, data1, data2, data3, data4, data5, data6, data7,  x = 160, y = 240;
var mySound;
let myCanvas;
var randomImageLocation;
let img = [];
var index = 0;
var typed="";
var ellipsecolor = 44;
var timer = 10;
var nextTime = timer;
let button;
let anotherStrata;
let myfi;
let datta1;

function preload() {
  data1 = loadStrings('assets/newtxt/1.txt');
  data2 = loadStrings('assets/newtxt/2.txt');
  data3 = loadStrings('assets/newtxt/three.txt');
  data4 = loadStrings('assets/newtxt/four.txt');
  data5 = loadStrings('assets/newtxt/five.txt');
  data6 = loadStrings('assets/newtxt/six.txt');
  data7 = loadStrings('assets/newtxt/seven.txt');
  data8 = loadStrings('assets/newtxt/8.txt');
  data9 = loadStrings('assets/newtxt/9.txt');
  data10 = loadStrings('assets/newtxt/ten.txt');
  data11 = loadStrings('assets/newtxt/11.txt');
  data12 = loadStrings('assets/newtxt/12.txt');
  data13 = loadStrings('assets/newtxt/13.txt');
  data14 = loadStrings('assets/newtxt/14.txt');
  data15 = loadStrings('assets/newtxt/15.txt');
  data16 = loadStrings('assets/newtxt/16.txt');
  img[0] = loadImage("img/img0.png");
  img[1] =  loadImage("img/img1.png");
  bg = loadImage("img/background.jpg");
}


function setup() {
  let createcanvas = createCanvas(window.innerWidth /2 , window.innerHeight - 150);
  createcanvas.parent('mycanvas');
  bg = loadImage("img/background.jpg");
  textFont('avenir');
  textSize(20 + (mouseX / width)*72);
  frameRate(30);
   fill('beige');
   lines = ["click to place your order!"];

  // create a markov model w' n=4
  markov = new RiMarkov(8);

  datta1 = data1.join(' ');
  datta2 = data2.join(' ');

  datta16 = data16.join(' ');
  // load text into the model
  markov.loadText(data1.join(' '));

在 p5.js match()分别matchAll()可用于查找 Regular expression 的出现或文本中的字符串。

查看示例:

function setup() {
    createCanvas(400, 200);
}

function draw() {
    var string = 'Hello World!';
    
    var str1 = match(string, "World");
    var str2 = match(string, "Dog");

    textSize(50);
    text(str1 ? str1 : "not found", 20, 70);
    text(str2 ? str2 : "not found", 20, 130);
}
