1. 请求数据失败后页面就一直报错，需强刷才能继续进行下去
解决方案： try catch
2. 在中chrome中记住密码然后密码框会自动记住密码，解决方案
已开始设置密码框的type="text" ，在得焦的时候，把其type改成password即可
3. .文本域自动撑开
4. 识别html
dangerouslySetInnerHTML
5. select call put 用法
select 可以获取到 state 中文件的值 let param = yield select(state=.{return state.common.param}) // common model的命名
call const res = yield call('请求借口','参数')
put yield put({type:'reducers保存文件名称',payload:'参数'}) // 保存数据
yield put({type:'当前文件下函数名称',payload:'参数'}) // 请求当前modal的函数
6. react 可拖拽弹窗

7. setFieldsValue使用
myForm.setFieldsValue({
['vc_centerno']: paramData.convertMap[i].VC_CENTERNO,
});
8. setFields 使用
myForm.setFields({
VC_WORKTIME: {
value: '',
}
});
