这段代码为什么先显示的是New text!?
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>innerHTML</title>
</head>
<body>
<p id="con">Hello World!</p>
<script type="text/javascript">
var mycon=document.getElementById("con");
document.write("p标签的原始内容："+mycon.innerHTML+"<br>");
mycon.innerHTML="New Text!";
document.write("p标签修改过的内容："+mycon.innerHTML);
</script>
</body>
</html>
