这是Jenkins哈希的采用版本，从这里借来的

export function createDeterministicRandom(): () => number {
  let seed = 0x2F6E2B1;
  return function() {
    // Robert Jenkins’ 32 bit integer hash function
    seed = ((seed + 0x7ED55D16) + (seed << 12))  & 0xFFFFFFFF;
    seed = ((seed ^ 0xC761C23C) ^ (seed >>> 19)) & 0xFFFFFFFF;
    seed = ((seed + 0x165667B1) + (seed << 5))   & 0xFFFFFFFF;
    seed = ((seed + 0xD3A2646C) ^ (seed << 9))   & 0xFFFFFFFF;
    seed = ((seed + 0xFD7046C5) + (seed << 3))   & 0xFFFFFFFF;
    seed = ((seed ^ 0xB55A4F09) ^ (seed >>> 16)) & 0xFFFFFFFF;
    return (seed & 0xFFFFFFF) / 0x10000000;
  };
}

你可以这样使用它:

const deterministicRandom = createDeterministicRandom()
deterministicRandom()
// => 0.9872818551957607

deterministicRandom()
// => 0.34880331158638

SIN(id + seed)是一个非常有趣的替代RANDOM函数，不能像SQLite一样播种:

我写了一个函数，返回一个种子随机数，它使用数学。罪恶有一个很长的随机数，并使用种子从其中挑选数字。

使用:

seedRandom("k9]:2@", 15)

它将返回您的种子号码 第一个参数是任意字符串值;你的种子。 第二个参数是返回多少位数字。

     function seedRandom(inputSeed, lengthOfNumber){

           var output = "";
           var seed = inputSeed.toString();
           var newSeed = 0;
           var characterArray = ['0','1','2','3','4','5','6','7','8','9','a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','y','x','z','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','U','R','S','T','U','V','W','X','Y','Z','!','@','#','$','%','^','&','*','(',')',' ','[','{',']','}','|',';',':',"'",',','<','.','>','/','?','`','~','-','_','=','+'];
           var longNum = "";
           var counter = 0;
           var accumulator = 0;

           for(var i = 0; i < seed.length; i++){
                var a = seed.length - (i+1);
                for(var x = 0; x < characterArray.length; x++){
                     var tempX = x.toString();
                     var lastDigit = tempX.charAt(tempX.length-1);
                     var xOutput = parseInt(lastDigit);
                     addToSeed(characterArray[x], xOutput, a, i); 
                }                  
           }

                function addToSeed(character, value, a, i){
                     if(seed.charAt(i) === character){newSeed = newSeed + value * Math.pow(10, a)}
                }
                newSeed = newSeed.toString();

                var copy = newSeed;
           for(var i=0; i<lengthOfNumber*9; i++){
                newSeed = newSeed + copy;
                var x = Math.sin(20982+(i)) * 10000;
                var y = Math.floor((x - Math.floor(x))*10);
                longNum = longNum + y.toString()
           }

           for(var i=0; i<lengthOfNumber; i++){
                output = output + longNum.charAt(accumulator);
                counter++;
                accumulator = accumulator + parseInt(newSeed.charAt(counter));
           }
           return(output)
      }

这里有很多很好的答案，但我有一个类似的问题，即我希望Java的随机数生成器和我最终在JavaScript中使用的任何东西之间的可移植性。

我找到了java-random包

假设种子相同，这两段代码有相同的输出:

Java:

Random randomGenerator = new Random(seed);
int randomInt;
for (int i=0; i<10; i++) {
    randomInt = randomGenerator.nextInt(50);
    System.out.println(randomInt);
}

JavaScript:

let Random = require('java-random');
let rng = new Random(seed);
for (let i=0; i<10; i++) {
    let val = rng.nextInt(50);
    console.log(val);
}

不，就像他们说的，不可能播种Math.random() 但你可以安装外部包，为这做准备。我使用这些包，可以安装使用这些命令

npm i random-seed

该示例来自包文档。

var seed = 'Hello World',
rand1 = require('random-seed').create(seed),
rand2 = require('random-seed').create(seed);
console.log(rand1(100), rand2(100));

对于一个固定的种子有一个简单的方法:

function fixedrandom(p){
    const seed = 43758.5453123;
    return (Math.abs(Math.sin(p)) * seed)%1;
}
