在uniapp中,要实现监听截图的功能,可以使用uni.addInterceptor方法来拦截路由跳转事件。首先,在APP.vue文件中的onLaunch方法中以下代码:
```javascript
onLaunch: function () {
let that = this;
uni.addInterceptor('navigateTo', {
success(e) {
that.watchRouter();
},
});
uni.addInterceptor('redirectTo', {
success(e) {
that.watchRouter();
},
});
uni.addInterceptor('reLaunch', {
success(e) {
that.watchRouter();
},
});
uni.addInterceptor('switchTab', {
success(e) {
that.watchRouter();
},
});
uni.addInterceptor('navigateBack', {
success(e) {
that.watchRouter();
},
});
that.watchRouter();
},
```
然后,在methods中定义watchRouter方法,用于监听uniapp页面路由跳转事件:
```javascript
methods: {
watchRouter() {
console.log('监听uniapp页面路由跳转');
},
},
```
这样,每次页面跳转时,都会触发watchRouter方法,从而实现了监听截图的功能。
