需要等dom加载完了再操作



<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

    <head>

        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

        <title>Insert title here</title>



    </head>

    

    <body>

        <textarea rows="10" cols="80" id="text"></textarea>

        <script type="text/javascript">

            document.getElementById("text").value = "Hello";
