这是一个十分有用的组件,可用于生成一个数据的编辑form,他是MST Library 3.1一个十分重要的组件,可以实现dbo form和dbo form的循环嵌套,而且控制在一个form中,同时支持dbo form中再次嵌套自定义的widget组件。
很多PHP框架,将form的生成写在函数,这是无可厚非的,但是你无法接收在生成一个form的时候,循环调用用户函数所付出的性能成本,这时候,构建一个php和html混编的代码,远比循环执行函数的性能要高。
而且,多数时候,我们知道一个数据对象的结构,也已经定义了数据对象的每个字段的值类型,我们真的没有必要再去手动写什么form,或者还要用代码去判断,这个用select,那个用textarea什么的。
