Question

我正在创建一个网站，管理员用户可以在该网站中动态创建自定义测验，并将其设置为一组用户。用户可以根据需要添加任意数量的问题，然后在正确答案字段旁边选择一个单选值。

我尝试将数据库中的值名称作为数组输入，并通过数组中的项目数实现列，但是没有运气向数据库提交任何内容，但是它表示无法连接到本地服务器。

如何根据函数Add（）的调用次数创建相应的列数，并在列中使用位类型将正确答案（通过无线电选择）设置为true？

    <form action="" method="POST">
    <fieldset id="input1-wrapper">
       <legend>Quiz Storage</legend>
       <p>Year: <input type="text" name="year" placeholder="Year" value="{{request.form.year}}"><br /></p>
       <p>Topic: <input type="text" name="topic" placeholder="Topic" value="{{request.form.topic}}"><br /></p>
       <p>Title: <input type="text" name="title" placeholder="Title" value="{{request.form.title}}"><br /></p>
    </fieldset>

  <fieldset id="fieldset">
    <legend id="legend">Questions</legend>
    <div id="placeholder">
        <div id="template">
            <p>Question: <br><input type ="text" size="80" name="ques[]" value="{{request.form.question }}"/><br /></p>
            <p>Answer 1: <br><input type ="text" size="80" name="ans1[]" value="{{request.form.answer1 }}"/><input type="radio" value="true"><br /></p>
            <p>Answer 2: <br><input type ="text" size="80" name="ans2[]" value="{{request.form.answer2 }}"/><input type="radio" value="true"><br /></p>
            <p>Answer 3: <br><input type ="text" size="80" name="ans3[]" value="{{request.form.answer3 }}"/><input type="radio" value="true"><br /></p>
        </div> <!-- template -->
    </div> <!-- placeholder -->
    <p><button type="button" name="Submit" onclick="Add();">Add new item</button></p>
  </fieldset>
</form>

<p><button type="button" name="Submit">Submit</button></p>

<script>
var _counter = 0;
function Add() {
    _counter++;
    var oClone = document.getElementById("template").cloneNode(true);
    oClone.id += (_counter + "");
    document.getElementById("placeholder").appendChild(oClone);
}
</script>

SQLite代码：（python）

#Insert quiz titles into SQLite database
def register_quiz():
    try:
        print("register_quiz")
        db=sqlite3.connect(dbname)
        print(sqlite3.version)
        db.row_factory=sqlite3.Row
        cursor = db.cursor()
        print("Topic = " + request.form[topic'])
        cursor.execute('''INSERT INTO quizzes (Year, Topic, Title) VALUES (?,?,?)''', (request.form['first_name'],request.form['last_name'], request.form['passwordID']))
        db.commit()
    except Error as e:
        print(e)
    finally:
        db.close()
