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
