封装一个use方法 export function useSmsBehavior(data: TData){ const smsBehavior = Behavior({ data: { useName: "", }, methods: { test(){ ... } }, ... }); return { data: data as TData & { // add data in behavior useName: string; }, smsBehavior, }; } 使用Behavior const {smsBehavior, data} = useSmsBehavior({money: 100}); Component({ behaviors: [smsBehavior], properties: {}, data, method: { getMoney(){ console.log(this.data.money, this.data.userName); this.test(); } } } 方法 declare namespace WechatMiniprogram.Page { interface ILifetime { test():void; } } declare namespace WechatMiniprogram.Component { interface InstanceMethods { test(): void; } } 方法的处理可能会污染没有使用behavior的页面。如果不怕麻烦也可以把properties、methods丢进use方法里处理一下。
