代码不是按照顺序依次执行吗？为什么<p id="con">Hello world!</p>这一行结果输出的却是"New text!"？谢谢告知。

<p id="con">Hello world!</p>
<script>
var mycon=document.getElementById("con");
document.write("P标签原始内容为"+mycon.innerHTML+"<br/>");
mycon.innerHTML="New text!";
document.write("P标签修改内容为"+mycon.innerHTML);
</script>
</body>
</html>
