书上说该代码点击连接后会替换文本，然而我没有发生，是哪里写错了吗？
- <html>
- <head>
- <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
- <script type="text/javascript">
- var d1 = document.getElementById("div1");
- var a_link = document.getElementById("answer_link");
- a_link.onclick = function()
- {
- d1.innerHTML = "That is easy, the answer is <strong>4</strong>!";
- return false;
- };
- </script>
- </head>
- <body>
- <div id="div1">
- What is 2+2?
- </div>
- <div id="div2">
- <a href="answer.html" id="answer_link">Get the answer</a>
- </div>
- </body>
- </html>
