问题描述 页面中实现了 componentWillPreload(),则第二次及之后进入该页面时打印 this.$componentType 得到的值是 'COMPONENT'
this.$componentType
'COMPONENT'
复现步骤
/* xx.tsx */ export default class Page extends Taro.PureComponent<> { componentDidMount () { console.log('componentType: ', this.$componentType) } componentWillPreload (params: { [p: string]: any }): any {} render () { return ( <View /> ) } }

补充信息
@tarojs/taro-weapp/src/native-api.js 中:
@tarojs/taro-weapp/src/native-api.js
function processApis (taro) { // ... if (key === 'navigateTo' || key === 'redirectTo' || key === 'switchTab') { let url = obj['url'] ? obj['url'].replace(/^\//, '') : '' if (url.indexOf('?') > -1) url = url.split('?')[0] const Component = cacheDataGet(url) if (Component) { const component = new Component() if (component.componentWillPreload) { // ... cacheDataSet(preloadInitedComponent, component) } } } // ... }
new Component() 没有传入 isPage 参数
new Component()
@tarojs/taro-weapp/src/creat-component.js 中:
@tarojs/taro-weapp/src/creat-component.js
function createComponent (ComponentClass, isPage) { // ... const weappComponentConf = { data: initData, created (options = {}) { if (isPage && cacheDataHas(preloadInitedComponent)) { this.$component = cacheDataGet(preloadInitedComponent, true) } else { this.$component = new ComponentClass({}, isPage) } // ... }, // ... } // ... return weappComponentConf }
如在 cache 中找到 preload 已经初始化的组件则直接取用缓存中的实例,所以此时 this.$component 的 isPage 为 false
this.$component
