这里的问题在于,当用户切换表单组件时,是否该保留之前的表单组件的校验信息和值。
还有个 getFieldInstance API 的,这样虽然切换没问题,但是 getFieldInstance 时会拿到 undefined. Lines 290 to 291 in 08d3c15
|
虽然单测没挂,但之前的单测都没有考虑动态切换组件会导致的情况。 所以补充单测时,需要梳理对已有的 API 的可能影响,然后都补充单测。之前 nested field 就是没有考虑到对已有 API 的影响才爆了那么多的问题。 |
下面立刻就绑定了,这里应该没有修改之前的逻辑。 Line 304 in 08d3c15

这个 PR 是要解决先 B mount 再 A unmount 的问题,在 A unmount 时就会删除引用了。 |

换了一个思路做,unmount 的时候留一个缓存。如果相同的 name 再次注册,则恢复现场。

我看到在这个简单例子里,替换组件的触发顺序是先 mount 再 unmount @afc163 |
这个修改可以同步到 form@1.x 吗?在用 antd@2,一些动态 fields 的值在提交时无法获取,很头痛 |
@jaredleechn 同求 |

直接使用createForm会丢失antd封装的必输(*号)及校验显示,所以第二条不需要改 |
@jaredleechn 我在1.4.x修复了这个问题,但是采用了和官方不一样的解决方案。以下是antd 2.x的替换步骤。
