我正在尝试使用 yql 显示来自谷歌新闻的 rss 提要。目前,如果您在表单中输入邮政编码,它会工作一次,但如果不刷新页面,我无法输入另一个邮政编码。任何帮助将不胜感激!

<script>
function top_stories(o){
var items = o.query.results.item;
var output = '';
var no_items=items.length;
for(var i = 0; i < 4; i++) {
var title = items[i].title;
var link = items[i].link;
var desc = items[i].description;
output += "<h3><a href='" + link + "'>"+title+"</a></h3>" + desc + "<hr/>";
}
document.getElementById('results').innerHTML = output;
}
