好的，这是我从你那里得到的东西，你能检查一下这是否正确吗?我不能对书中的大部分内容进行编辑，所以它必须保持这种格式，im guessing..hope，你可以帮上忙
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
/* <![CDATA[ */
/* ]]> */
document.getElementById( news ) .innerHTML='newsItem1';
var newsItem1 = "L'AQUILA, ITALY (AP) - L'Aquila's chief prosecutor announced an investigation into allegations of shoddy construcation as workers continued to scour the rubble for people still missing after a devastating earthquake five days ago. http://in.reuters.com/article/idUSWBT01103020090411;
var newsItem2 = "WASHINGTON (Reuters) - President Barack Obama said on Friday the recession-hit US ecomony was showing 'glimmers of hope' despite remaining under strain and promised further steps in coming weeks to tackle the finicial crisis. http://in.reuters.com/article/idUSWBT01103020090411";
var newsItem3 = "(eWeek.com) - Apple is close to hitting 1 billion downloads from its App Store and plans on prize giveaway for whoever downloads the billionth application that includes a MacBook Pro and an iPod Touch. http://www.eweek.com/c/a/application-development/eweek-newsbreak-april-13-2009/";

尽管对你的任务来说可能太晚了，但我认为我应该指出代码中的一些错误，并尝试实现你想要的东西，即在单击相应的选择选项时显示不同的newsItems。
新闻应在声明id为‘
document.getElementById( 'news' ).innerHTML='newsItem1';’的textbox标记之后写入，否则将提供空值。
- 在
<option onclick="document.newsHeadlines.news.value=newItem1>中，有一个拼写错误(newItem1应该是newsItem1)，并且onclick属性值不正确。要正确选择文本框并在其中显示所需的文本，应使用以下方法：
onclick="document.getElementById('name').value=newsItem1"。
对其余选项使用相似的值。
