為什么還是顯示的I love JavaScript
<h2 id="con">I love JavaScript</H2>
? <script type="text/javascript">
? ? var mychar= document.getElementById("con");
? ? mychar.style.color = "red";
? ? maychar.innerHTML = "I LOVE YOU";
? ? document.write(maychar);
? </script>

第一個(gè)錯(cuò)誤maychar.innerHTML 多了個(gè)a;第二個(gè)，最好把腳本寫在body后面，這是個(gè)好習(xí)慣，寫在前面最好加window.onload

maychar.innerHTML = "I LOVE YOU";
maychar多了個(gè)y，會(huì)不會(huì)是這個(gè)錯(cuò)誤。
