我是看教程写的关键帧动画,教程代码地址:https://developers.weixin.qq.com/miniprogram/dev/framework/view/animation.html 我写的方法是 onLoad: function () { this.setData({ statusBarHeight: app.globalData.statusBarHeight, navBarHeight: app.globalData.navBarHeight }); this.animate('.dialog_body', [ { scale: [0.3, 0.3], ease: 'ease-out' }, { scale: [1, 1], ease: 'ease-in' }, ], 1000); }, 编译的时候报错 VM461:1 thirdScriptError this.animate is not a function;at pages/filterdialog/filterdialog page lifeCycleMethod onLoad function TypeError: this.animate is not a function     at l.onLoad (http://127.0.0.1:26109/appservice/pages/filterdialog/filterdialog.js:58:10)     at l.(http://127.0.0.1:26109/appservice/__dev__/WAService.js:1:1569573)     at l.__callPageLifeTime__ (http://127.0.0.1:26109/appservice/__dev__/WAService.js:1:1569313)     at Tt (http://127.0.0.1:26109/appservice/__dev__/WAService.js:1:1588940)     at http://127.0.0.1:26109/appservice/__dev__/WAService.js:1:1592274     at xt (http://127.0.0.1:26109/appservice/__dev__/WAService.js:1:1592767)     at Function.(http://127.0.0.1:26109/appservice/__dev__/WAService.js:1:1596300)     at i.(http://127.0.0.1:26109/appservice/__dev__/WAService.js:1:1565163)     at i.emit (http://127.0.0.1:26109/appservice/__dev__/WAService.js:1:574700)     at Object.emit (http://127.0.0.1:26109/appservice/__dev__/WAService.js:1:562185) console.error @ VM461:1 errorReport @ VM478 WAService.js:1 thirdErrorReport @ VM478 WAService.js:1 (anonymous) @ VM478 WAService.js:1 (anonymous) @ VM478 WAService.js:1 __callPageLifeTime__ @ VM478 WAService.js:1 Tt @ VM478 WAService.js:1 (anonymous) @ VM478 WAService.js:1 xt @ VM478 WAService.js:1 (anonymous) @ VM478 WAService.js:1 (anonymous) @ VM478 WAService.js:1 i.emit @ VM478 WAService.js:1 emit @ VM478 WAService.js:1 (anonymous) @ VM478 WAService.js:1 (anonymous) @ VM478 WAService.js:1 n @ VM476 asdebug.js:1 (anonymous) @ VM476 asdebug.js:1 (anonymous) @ VM476 asdebug.js:1 _ws.onmessage @ VM476 asdebug.js:1 VM527:4 Tue Dec 17 2019 16:33:18 GMT+0800 (中国标准时间) sitemap 索引情况提示 VM461:1  根据 sitemap 的规则[0]，当前页面 [pages/filterdialog/filterdialog] 将被索引 console.warn @ VM461:1 (anonymous) @ VM527:6 (anonymous) @ VM527:13... 请问为什么官方实例代码不报这个错,而我就报这个错
