Question

var game = prompt('Do you want to play?');

var i = 0;
do {
  if (prompt === 'Yes');
  {
    var game2 = prompt('Enter your word.');
    var game3 = prompt('Do you want to play again?');
  }
  i++;
} while (game3 !== 'No');
{
  console.log(game3);
}

console.log("You're words are: " + game2);

如何获取此循环输出的所有单词并使用它构建一个字符串？

前：如果我所有的话都是“篮球，足球，赛车”

我希望他们输出像 - ＆gt;篮球足球赛

Answer 1

希望这会有所帮助......

var game = prompt('Do you want to play?');
var game2 = '';
var space = ' ';
var i = 0;
do {
  if (prompt === 'Yes');
  {
    game2 = game2 + space  + prompt('Enter your word.');
    var game3 = prompt('Do you want to play again?');
  }
  i++;
} while (game3 !== 'No');
{
  console.log(game3);
}

prompt("You're words are: " + game2);

您的代码看起来有些问题。如果将所有响应放入数组中，则可以使用.join方法。

var game = prompt('Do you want to play?');

var i = 0;
var words = [];
do {
  // if (prompt === 'Yes'); // this isn't doing anything
  // {
    words.push(prompt('Enter your word.'));
    var game3 = prompt('Do you want to play again?');
  // }
  i++;
} while (game3 !== 'No');
{
  console.log(game3);
}

console.log("You're words are: " + words.join(' '));

Answer 3

试试这个

var words = [];

var i = 0;
do {
  var game = prompt('Do you want to play' + ((words && words.length) ? ' again' : '') + '? (type yes to continue else exit)');
  if(game && game.toLowerCase() === 'yes') {
    var word = prompt('Enter your word.');
    if(word) {
      words.push(word);
    }
  }
} while (game && game.toLowerCase() === 'yes');

if(words && words.length) {
  console.log("You're words are: " + words.join(', '));
} else {
  console.log("no words selected!");
}

Answer 4

根据我的问题，我应该理解这一点。

var game = prompt('Do you want to play?');

var i = 0;
var game2="";
do {
  if (prompt === 'Yes');
  {
    game2 += " "+prompt('Enter your word.');
    var game3 = prompt('Do you want to play again?');
  }
  i++;
} while (game3 !== 'No');
console.log(game3);
console.log("You're words are: " + game2);

基本上，你只是动态连接。

你可以使用String Array：

var gameArr =[];
gameArr.push(prompt('Do you want to play?'));

var i = 0;
do {
  if (prompt === 'Yes');
{
  gameArr.push(prompt('Enter your word.')); // This will append new string in current string.
  gameArr.push(prompt('Do you want to play again?'));// this also append the new string.
}
i++;
} while (game3 !== 'No');
{
  console.log(game3);
}

console.log("Your words are: " + gameArr[1]);

如果您不确定如何从阵列gameArr []获得您的回复，请告诉我。
