Blackberry Webworks（小部件）JavaScript 和XML/JSON 帮助

场景如下...

构建一个 Blackberry WebWorks（小部件），用作远程网站的门户。大多数页面都是远程的。我是用户可定制的主页，用户可以添加信息和链接。

我在使用 JDE 时执行此操作的方法是拥有一个 xml 属性文件，我可以使用所需信息添加/编辑/远程节点，并且每次运行应用程序时我都可以处理该文件。但是，为了让 webworks 应用程序正常工作，我需要通过向 html 页面添加信息来完成这一切。

我相信我需要通过 javascript 来完成此操作，但是我几乎没有 javascript 经验，甚至更少的黑莓 API 经验。

因此，我正在寻找一个从头到尾的示例，说明如何通过 JavaScript 加载保存的 XML 或 JSON 属性文件，以便动态构建我的小部件的主页。此外，我还在寻找如何通过 javascript 从配置文件添加/编辑/删除 xml 或 json 对象的示例。

我一直在寻找，不确定我是否走在正确的道路上，但我没有运气。我看过一些如何在 microsoft/mozilla 浏览器中编辑 XML 的示例，所以我不确定这是否相同......如果是这样，只是寻找一些确认。

基本上，这是我的头脑告诉我需要发生的事情的概述......

<html>
...
<script>
//Read XML/JSON Properties file
// For each item loaded process and publish html source code
</script>
...
<!-- HTML to add desired information back to properties file -->
<script>
// Perform insert/edit/delete of XML/JSON
</script>
...
</html>

Here is the scenario...

Builing a Blackberry WebWorks (widget) that is used as a portal to a remote website. Most of the pages are remote. I am user customizable homepage that users can add information and links.

The way I would do this in using the JDE is to have an xml properties file that I could add/edit/remote nodes with the desired information and everytime the app would run I could process that file. However, for the webworks app to work, I need to accomplish this all via adding information to the html page.

I believe that I need to do this via javascript, however I have little javascript experience and even less blackberry API experience.

So I am looking for a beginning to end example of how to load a saved properties file either XML or JSON via JavaScript that can dynamically build the homepage of my widget. In addition, I am looking for examples of how to add/edit/remove the xml or json objects from the config file via javascript as well.

I have searched and searched, not sure if I am on the right track or not, but I have had no luck. I have seen some examples of how to edit XML in microsoft/mozilla broswers, so I am not sure if this is the same or not... If so just looking for some confirmation.

Basically here is an outline of what my head tells me needs to happen...

<html>
...
<script>
//Read XML/JSON Properties file
// For each item loaded process and publish html source code
</script>
...
<!-- HTML to add desired information back to properties file -->
<script>
// Perform insert/edit/delete of XML/JSON
</script>
...
</html>

Thanks for your help!!!
