一张图解析FastAdmin中的FormBuilder表单生成器

 

功能描述

在使用FastAdmin一键生成CRUD后，默认的生成的都是原生HTML的组件代码，会有许多不熟悉前端的小伙伴改动起来会比较费劲。其实在FastAdmin中有一个简单的FormBuilder，但是它只能生成一些简单的文本框或下拉框，像FastAdmin中常用的动态下拉框、城市选择框、联动框，它就没法实现了。从1.0.1.20180630_beta版本开始，我们可以使用全新的FormBuilder用于生成我们的组件了。

千万别忘记在对应的JS方法中添加代码Form.api.bindevent("form[role=form]");进行组件初始化，否则部分组件会不生效。

通用属性

$name 通常为我们组件的名称，我们在后台接收时可以通过这个名称来获取到它所对应的值
$value 通常为我们数据库中的值，在新增的时候通常为空，在修改的时候通常需要是数据库中对应字段的值
$options 组件的扩展属性，通常为一一键值匹配并最终渲染在组件的属性中，通常我们使用的有data-rule/disabled/readonly/multiple等等，也常用于自定义组件属性。
