Angular 5- react 形式和动态形式之间的区别

Question

响应式(Reactive)和动态形式有什么区别？我对动态表单的理解是基于描述业务对象模型的元数据动态创建表单。我不清楚这个解释。

来自docs on Reactive forms

Reactive forms provide a model-driven approach to handling form inputs whose values change over time. This guide shows you how to create and update a simple form control, progress to using multiple controls in a group, validate form values, and implement more advanced forms.

和Dynamic forms ...

Building handcrafted forms can be costly and time-consuming, especially if you need a great number of them, they're similar to each other, and they change frequently to meet rapidly changing business and regulatory requirements. It may be more economical to create the forms dynamically, based on metadata that describes the business object model.

因此，动态表单是直接从组件中的代码创建的。如果您面临不断变化的需求并且您的表单需要不断更改，您甚至可以在不接触模板的情况下更改它们。他们使用响应式表单 来工作。响应式(Reactive)表单是一种从组件(而不是模板)描述表单的方式，因此您可以控制验证和与之关联的逻辑。
