俩个下拉框实现联动效果 #10466

Open coffin03 opened 3 months ago

coffin03 commented 3 months ago

实现场景:

使用编辑器操作面板在不修改源码的场景下,实现俩个下拉框接口联动效果

存在的问题:

在select1值变化回调中添加对select2的数据重新请求数据事件,在select2接口http配置中添加发送数据参数为select1,切换select值,select2重新请求了数据,但参数值拿到的是select1的旧值,并非当前值

当前方案:

表单项配置 strickMode: false

另外可以这个场景其实可以直接用这个机制 https://aisuda.bce.baidu.com/amis/zh-CN/docs/concepts/linkage#%E5%9F%BA%E6%9C%AC%E4%BD%BF%E7%94%A8

加了strictMode 没用

加了strictMode 没用

现在的应用场景是只使用编辑器的可视化面板进行配置 能不能用可视化面板在不更改源码的情况下实现这一需求

在chang 里加了 debounce防抖就可以拿到最新的值了
