Just The last "}" 无故显示错误。 “}”是死亡？第八次尝试。编码工作让我的大脑有点融化。发送帮助！我吓到了！无法解决这个问题。返回 1；我几乎要失去理智了。 1 和 0 的罐子。谢谢，如果你读了这个顺便说一句，只需阅读句子开头第一个单词的第一个字母。

【问题讨论】：

为什么有这么多makeid的？

标签： javascript html css

【解决方案1】：

您的 javascript 中缺少 2 个右括号，您没有关闭 document.getElementById 函数：

document.getElementById("submit").onclick = function() {
 console.log("Submitted prize. Prize ID:");
  function makeid(length) {
    var result           = '';
    var characters       = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
    var charactersLength = characters.length;
    for ( var i = 0; i < length; i++ ) {
      result += characters.charAt(Math.floor(Math.random() * charactersLength));
    }
    return result;
    console.log(makeid(27));
  }
} // add this

其他 getElementById 函数也是如此。如果您保持缩进相同，则可以防止这些错误。
