基于Prototype的文本框自动填充功能的实现

Implementation of automatic filling of texts based on Prototype

以医院管理系统医生开具药方模块中文本框自动填充功能的实现为例,详细介绍了如何利用Prototype框架和基于文本的数据交换格式JSON实现文本框的自动填充功能,介绍了Prototype框架中实现AJAX的异步通信时用到的关键技术,给出了具体实现过程及主要代码。实践证明,基于AJAX的异步请求原理实现的文本框的自动填充功能,不但方便了医护人员的使用,也大大提高了其工作效率,减少了病人的等待时间。

Taking the function of automatic filling of text in module of prescription in the hospital management system as an example, it is explained in detail how to use the Prototype framework and text-based data interchange format JSON to realize automatic filling of texts. The key technology used to realize the asynchronous communication of AJAX in Prototype framework, the concrete process of realization and the main code are introduced. The practice has proved that the function of the automatic filling of texts based on AJAX asynchronous request principle is not only convenient for hospital workers, but also greatly improves the work efficiency, and thus reduces the waiting time of patients.
