我有一个相对来说比较省力，校验完备，但不那么优雅的解决方案。 废话少说，代码如下： // use.ts function useBehavior<TData extends WechatMiniprogram.Behavior.DataOption, TProperty extends WechatMiniprogram.Behavior.PropertyOption, TMethod extends WechatMiniprogram.Behavior.MethodOption, TCustomInstanceProperty extends WechatMiniprogram.IAnyObject = Record<string, never>>(opt: Partial<WechatMiniprogram.Component.Data<TData>> & Partial<WechatMiniprogram.Component.Property<TProperty>> & Partial<WechatMiniprogram.Component.Method<TMethod>> & Partial<WechatMiniprogram.Component.OtherOption> & Partial<WechatMiniprogram.Component.Lifetimes> & ThisType<WechatMiniprogram.Component.Instance<TData, TProperty, TMethod, TCustomInstanceProperty>>) { const behaviorID = Behavior(opt) return { behaviorID, // 仅仅为了方便获取内部变量类型故 _optType: {} as typeof opt, } } export { useBehavior } // detailBehavior.ts import { useBehavior } from "@/utils/use" const { behaviorID, _optType, } = useBehavior({ properties: { detailId: { type: String, value: '' }, }, data: { isDetailLoading: false as boolean, detailLoadError: '', isDetail: false as boolean, }, observers: { 'detailId': function (newDetailId) { if (!newDetailId || this.data.isDetailLoading) { return } this.setData({ isDetailLoading: true, detailLoadError: '', isDetail: true }) const needSetData = {} this.getDetailByDetailId?.(this.data.detailId)?.then()?.catch((err) => { Object.assign(needSetData, { detailLoadError: err.toString() }) })?.finally(() => { Object.assign(needSetData, { isDetailLoading: false }) this.setData(needSetData) }) } }, methods: { getDetailByDetailId(id: number | string) { return Promise.resolve('') } } }) export default behaviorID // 此处已经把当前behavior特有的data(properties)和methods导出来了 export type DetailBehavior = typeof _optType // detail.ts import detailBehavior, { DetailBehavior } from './detailBehavior' import ortherBehavior, { BehaviorOrthers } from './detailBehavior' Component({ behaviors: [detailBehavior, ortherBehavior] data: { anyDataInThisComponent: {}, ...{} as DetailBehavior['data'] & BehaviorOrthers['data'] }, methods: { ...{} as DetailBehavior['methods'] & BehaviorOrthers['methods'] ortherSelfMethod(){ }, } })

老哥，我用的你的方法，中文+emoji混合解析出来的串再显示的中文部分会是乱码，英文+emoji就不会，难道是只针对emoji解析的？
