<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>document.getElementById</title>
</head>
<body>
<p id="con">JavaScript</p>
<script type="text/javascript">
? var mychar=document.getElementById("con");
? document.write("結(jié)果:"+mychar.innerText); //輸出獲取的P標簽。?
</script>
</body>

沒毛病。innerText也可以換成innerHTML
