所以我试图从XML文件中获取数据,但是当我通过它循环并希望得到" countyname"我只获得第一个,然后停止。 XMl错了吗?因为我尝试使用其他XML,并且我的代码能够将数据导入到我的tableview中。 最好的祝福! 菲利普

您的代码逻辑错误。让我解释一下为什么......我将对您的代码进行评论,最后您将了解它的错误。
var items = xml.documentElement.getElementsByTagName("county");
通过这一行代码,您可以获得所有&#34; county&#34; XML文件的元素。在您的情况下,只有一个元素。因此items
是Node.List
,只包含一个元素。
for (var i=0; i<items.length; i++) {
...
}
使用for
语句,您将遍历items
中的所有元素。换句话说,for
语句的内容将重复items.lenght
次。但是items
只包含一个元素!所以不会有迭代。
在您的陈述中,您要创建新行。但是只会创建一行,因为没有迭代。出于这个原因,你只得到第一个&#34; countyname&#34;标签
我希望你能理解你的错误......现在我为你的问题提供一个简单的解决方案:
var data = [];
var items = xml.documentElement.getElementsByTagName("countyname");
for (var i=0; i<items.length; i++) {
var row = Ti.UI.createTableViewRow({
title: items.item(i).getTextContent()
});
data.push(row);
}
itemsTable.data = data;
我的代码只列出标签名称为&#34; countyname&#34;的所有元素。根据您的XML文件,items
将是Node.List
,其中包含两个元素。然后使用for
语句,可以从列表中每个节点的textContent创建新行!
