初识智遥工作流软件——表单开发篇2

　　刚写两篇博客，就被博友批评了，看样子我的写作水平亟待提高，努力......。

 

　　由于公司也是刚安装了智遥工作流这软件，软件公司提供3个月免费试用。现在还是在试用阶段。领导交待我先做几个流程测试一下，看看是否符合实际需求。由于不熟悉，所以就只能从最简单最常用的“请假流程”入手了，还望大家见谅！以后再放上复杂的。

 

　　智遥工作流的表单，一键生成源代码功能确实不错，很对我这种懒人的胃口。但是自动生成的东西，肯定是无法满足用户需求的，所以必须是扩展方便，如果扩展不了，再怎么方便都是白搭。现在就来看看系统自动生成的源代码吧：

前台代码没什么好讲的，就是几个控件从上往下排列下来，也不用写CSS样式，也不用表格，简洁+简单。我喜欢。

智遥的顾问讲解了一下，后台代码组成，以及各个函数的功能作用。

1.BindMainData() 用于显示表单内容
2.SaveData() 当用户点击"暂存/转下一步"时候自动调用，保存数据
3.SaveCheck() 当用户保存的时候调用，提示是否有输错了的，漏输了之类的
4.EndFlow() 当用户点击结束的时候会自动调用，里面空的，啥都没执行，就是为了扩展而留下的，有时候需要在流程结束的时候将数据写入到ERP或者HR系统中，这时就排上用场了。
5.GetCurrentFnid()这个太有用了，可以获得当前操作所处在的节点，用户可以根据需求自行扩展，比如控制输入权限之类的。
总结：自动生成的代码非常规范，整洁；没有使用高深的代码，至少我能轻松看懂。让人感觉这智遥工作流系统好简单啊。之前使用金和C6的时候，就觉得工作流好高深，动不动就得webservice，XML之类的。

 到目前为止，个人对这个智遥工作流很满意，希望以后制做复杂流程时，不出现各种不给力现象。
