准备:需要准备要扫描的图片地址和扫描成功后显示的模型
1.在components创建组件
index.js文件代码
html
Component({
properties: {

code: {
type: String,
value: '',
},
json: {
type: String,
value: '',
},
js: {
type: String,
value: '',
},
showBackBtn: {
type: Boolean,
value: false,
},
},
data: {
},
lifetimes: {
attached() {
wx.xrTitle = this.data.title;
}
},
methods: {
onClickBack() {
wx.navigateBack()
},
}
})
index.json代码

2.继续在components里面创建xr-ar-oceanWorld组件
index.js文件代码

4.在components组件里面创建common文件share-behavior.js
