小编路见不*_*一声吼的帖子

代码如下:

    import { Component } from '@angular/core';
    import { NavController, Platform } from 'ionic-angular';
    import { TranslateService } from '@ngx-translate/core';
    import { BarcodeScanner } from '@ionic-native/barcode-scanner';

    @Component({
        selector: 'page-home',
        templateUrl: 'home.html'
    })
    export class HomePage {
        constructor(public navCtrl: NavController, private translate: TranslateService, private barcodeScanner: BarcodeScanner) {

        }
        //Switch language 
       changelanguage() {
            let browserLang = this.translate.currentLang;
            this.translate.use(browserLang.match(/en/) ? 'zh' : 'en');
        }
        //Scan test
        ScanCode() {
            this.barcodeScanner.scan()
                .then((result) => {
                    console.log(result);
                })
                .catch((error) => {
                    alert(error);
                });
        }
    }
