我正在创建一个 WCF 服务,该服务将由客户端的纯 JavaScript 和客户端的一些 jQuery JavaScript 使用。
1) 我怎样才能实现普通的客户端 JavaScript,以便它以这样的方式调用 WCF 服务,以便立即检索 System.IO.Stream 的集合?此外,我将如何遍历在纯 JavaScript 端接收到的集合,以便可以将集合中的每个 System.IO.Stream 对象与 HTML 图像元素相关联?
2) 是否有可能实现使用 jquery 的 JavaScript 代码,以便它以这样的方式调用 WCF 服务,即一次检索 System.IO.Stream 的集合?此外,我将如何遍历使用 jQuery 的 JavaScript 接收的集合,以便可以将集合中的每个 System.IO.Stream 对象与 HTML 图像元素相关联?
