XForms/Adder
< XForms
该程序演示了从 XForms 应用程序示例调用 Web 服务的几种不同方法。该示例使用 HTTP POST 和 HTTP GET 方法，并展示了结果如何返回到模型中的实例以及如何用结果替换页面。它调用的 Web 服务是一个简单的 Web 服务，它将两个数字加在一起。
为了将结果使用 FireFox 放入模型中，请确保将 www.sa.kw.ua.sa 和 xforms-examples.google.com 添加到 FireFox 的工具/选项/安全/允许站点菜单中的 XForms 白名单中。这是必需的，因为我们的 Web 表单托管在一个域名上，但 Web 服务托管在另一个域名上。
