1、方案一，建立 sameEvent.js 通过对象 继承方式。
import {
sameEvent
} from '../sameEvent/index.js'
Page(Object.assign({
data: {
},
onLoad() {
},
}, sameEvent))
2、方案二，mixins 为 Page 增加 mixin 功能
/**
* mixins 为 Page 增加 mixin 功能
* 来源：https://segmentfault.com/a/1190000019527762
*/
const originPage = Page;
const originProperties = ['data', 'properties', 'options'];
const originMethods = ['onLoad', 'onReady', 'onShow', 'onHide', 'onUnload', 'onPullDownRefresh', 'onReachBottom', 'onShareAppMessage', 'onPageScroll', 'onTabItemTap'];
function merge (mixins, options) {
mixins.forEach((mixin) => {
if (Object.prototype.toString.call(mixin) !== '[object Object]') {
throw new Error('mixin 类型必须为对象！')
}
for (let [key, value] of Object.entries(mixin)) {
if (originProperties.includes(key)) {
options[key] = { ...value, ...options[key] }
} else if (originMethods.includes(key)) {
const originFunc = options[key];
options[key] = function (...args) {
value.call(this, ...args);
return originFunc && originFunc.call(this, ...args)
}
} else {
options = { ...mixin, ...options }
}
}
});
return options
}
Page = (options) => {
const mixins = options.mixins;
if (Array.isArray(mixins)) {
delete options.mixins;
options = merge(mixins, options)
}
originPage(options)
};
