提交时不起作用

但丁

我需要在用户单击“提交”按钮以检查其答案并根据给出的答案返回文本后执行的功能。当我输入文本并单击提交按钮时，什么也没有发生。单击提交按钮应执行该功能。然后根据答案是对还是错，返回一些文本。我怀疑语法中有某些内容，但是我已经检查了无数次。

这是我的代码：

 <!DOCTYPE html>
<html lang="en-us">
    <head>
        <meta charset="UTF-8">
        <title>Riddle Me This</title>
        <link href="HW6Part2.css" type="text/css" rel="stylesheet"/>

        <body>
            <div class="text">
                <h1 class="head1">First Riddle:</h1>
                <p class="first">The more you take, the more you leave behind. What am I?</p>
                <h1 class ="head2">Second Riddle:</h1>
                <p class="second">What has a head, a tail, is brown, and has no legs?</p>
                Input your answer: <br><br>
                <form onsubmit="checkAnswer(event)">
                    Input your answer for the first riddle: <br><br>

                <p id="response1"></p>

            <script>
            //Initiate function:
function checkAnswer() {
    e.preventDefault();
    //Get the user's input
    var ans = document.getElementById('a1');
    var ans2 = document.getElementById('a2');
    //Compare input to the right answer
    if (ans != 'footsteps' && ans2 != 'penny'){
    document.getElementById('response1').innerHTML = 'Both answers are wrong! Try harder!';}
    else if (ans == 'footsteps' && ans2 != 'penny'){
    document.getElementById('response1').innerHTML = 'You have solved the first riddle, but failed on the second! Try harder!';}
    else if (ans != 'footsteps' && ans2 == 'penny'){
    document.getElementById('response1').innerHTML = 'You have solved the second riddle, but failed on the first! Try harder!';}
    else{
document.getElementById('response1').innerHTML = 'You have solved both riddles, smartass. Have a cookie!';}
}

// When it loses focus call checkAnswer()
a1.addEventListener('blur', checkAnswer, false);

            </script>

            <br>
