我不知道如何将来自 document.write 的输入存储在变量中

Question

我要求输入团队名称，因为我正在尝试创建一个程序，该程序将根据分数创建 table。我必须用 JS 编写输入代码，因为它在 OnClick 函数中。但是，我不了解如何存储用户输入（在变量或其他方式中。）

我试过一些方法，例如将实际 document.write 存储在变量中。

<!DOCTYPE html>
<html>
<body>

<h1>Soccer Table Generator</h1>
<h3>How Many Teams Would You Like?</h3>

<select id="num_of_teams">
    <option value="Select" selected>Select</option>
    <option value="2">2</option>
    <option value="3">3</option>
    <option value="4">4</option>
</select>

<script>
var menu = document.getElementById("num_of_teams");
menu.addEventListener("change", generateData);

function generateData(event) {
  if (menu.value == '2') {
    alert("You have selected 2 teams. Would you like to proceed?");
    document.write ("What is the name of your first team?");
    var teamone = document.write ("<input type = 'text' value = 
'input here'<input>");
document.write ("What is the name of your second team?");
  } else if (menu.value == '3') {
    alert("You have selected 3 teams. Would you like to proceed?");

  } else if (menu.value == '4') {
    alert("You have selected 4 teams. Would you like to proceed?");
  }

}
</script>


</body>
</html>

我希望输入存储在一个变量中并打印（当我使用代码打印它时），但是当我尝试它时它显示未定义。

如果您想要一种获取用户输入的简单方法，您可以使用Window.prompt。例如：

let first_team = prompt("What is the name of your first team?");
