让用户设计一个表单和其中的字段 [英] Let the user design a form and the fields in it

问题描述

我正在开发一个应用程序，其中我想让用户设计一些表单并确定表单中的字段。

I am developing an application in which I would like to let the users design some forms and decide the fields that are in the form.

一个例子比一个糟糕的解释，所以让我举个例子说明，作为最终用户可以定义一个表单，该表单中的字段，或通过添加或删除字段来定制现有的表单。

An example is better than a poor explanation, so let me put the example of Microsoft CRM in which you as end user can define a form, the fields in that form, or customize existing forms by adding or removing fields.

有没有一些标准的方法来做这个？任何人都知道要使用的组件？或者在类似的功能中工作？

Is there some standard way to do this?, Anyone knows of components to use? Or worked in a similar functionality?

任何put将不胜感激。

Any put would be appreciated.

推荐答案

这不是一个微不足道的事情，有成千上万的方法来实现这一点。这取决于许多因素 - 例如您的用户是否能够发布其创建的表单，用户可以更新其表单（带来表单和数据版本管理问题），是否提供可视化设计师，您是否将提供声明式设计语言，您如何要将数据填充到表格中，是用户从有限的一组可用字段中提取的字段，还是用户可以创建全新字段等。

This is not a trivial undertaking and there are thousands of ways to accomplish this. It depends on many factors - e.g. will your users be able to "publish" their created forms, can the users update their forms (brings in form- and data-version management issues), will you provide a visual designer, will you provide a declarative design language, how do you want to store the data filled into a form, are the fields chosen by the user pulled from a finite set of available fields or can the user invent wholly new fields, etc.

在一个完整的电子表格包中，您本质上是创建一个用于表单创建的可视化IDE以及一个编译器，用于生成用户表单的可填写，运行时实现。为了使系统有用，您还必须包括管理功能（搜索，归档，导入，导出等）。

In a full-blown electronic forms package, you are, essentially, creating a visual IDE for form creation along with a "compiler" that produces the fill-able, run-time implementation of the user's forms. To make the system useful, you will also have to include management features (search, filing, import, export, etc.).

如果您不想解决这些问题自己，有很多 eforms 包在那里。成本从免费到数万美元。

If you don't want to tackle these issues yourself, there are many eforms packages out there. Cost ranges from free to tens of thousands of dollars.
