在社区居民电子健康档案(EHR)系统中,如何快速、有效地实现在Web上绘制儿童生长监测图,是提高居民使用该系统体验的研究热点。结合当前新兴的Ajax和GDI+技术,当居民提交请求时,客户端采用预先设计的Ajax状态管理器处理请求,然后向服务器发送XMLHTTP请求,服务器端响应请求、采用GDI+编程实现图形的绘制并返回,最终实现儿童生长监测图在Web上发布。
In EHR system, how to quickly and effectively draw a child growth monitoring map on the Web is a research hotspot to improve the residents’ experience of using the system. Combined with the current emerging Ajax and GDI + technologies, when a resident submits a request, the client uses a pre-designed Ajax state manager to process the request and then sends an XMLHTTP request to the server. The server responds to the request and draws and returns the graphic using GDI + programming. The final child growth monitoring map posted on the Web.
