将用户/计算机分数添加到推文

Question

问题：当用户点击推特图标时，它会弹出一个推特框，但不会添加 USER_SCORE/COMPUTER_SCORE 变量的值。现在我只测试了 USER_SCORE。

我想我可以创建一个包含值的文本节点，并将其附加到框中，但这不起作用，我不确定还有什么真正起作用。

期望的结果：我想在点击推特按钮时将 USER_SCORE/COMPUTER_SCORES 的值添加到推文框。

Answer 1

将推文您的分数部分更改为以下内容：

  //tweet your score
  TWEET.addEventListener('click', function() {
    var message = "Your score was " + USER_SCORE + ". The computers score was " + COMPUTER_SCORE;
    window.open('https://twitter.com/intent/tweet?text=' + message);
  }, false );
