我正在尝试使用 Ionic Call Number Native插件
https://ionicframework.com/docs/native/call-number/
我安装了插件，将其导入app.module.ts和mypage.ts，我还将其添加到app.module提供程序。
这是我的 profil.ts ，您应该专注于 callhim 功能：
import { Component, ChangeDetectorRef } from '@angular/core';
import { IonicPage, NavController, NavParams } from 'ionic-angular';
import { NativeStorage } from '@ionic-native/native-storage';
import { EditaccountPage } from '../editaccount/editaccount';
import { AuthServiceProvider } from '../../providers/auth-service/auth-service';
import { Observable } from 'rxjs/Observable';
import { CallNumber } from '@ionic-native/call-number';
import * as _ from 'lodash';
/**
* Generated class for the MyaccountPage page.
*
* See https://ionicframework.com/docs/components/#navigation for more info on
* Ionic pages and navigation.
*/
@IonicPage()
@Component({
selector: 'page-profil',
templateUrl: 'profil.html',
})
export class ProfilPage {
public myAccountData;
public profilId;
public showInfoPers=true;
public showMetiers=false;
public showServices=false;
public colorInfo= "#3f4996";
public colorMetiers= "#fff";
public colorServices= "#fff";
constructor(public navCtrl: NavController, public navParams: NavParams, private nativeStorage: NativeStorage, public authServiceProvider: AuthServiceProvider, public changeDetectorRef: ChangeDetectorRef, private call: CallNumber) {
}
ionViewDidEnter() {
var th;
this.profilId = this.navParams.get('profilId');
console.log(this.profilId);
th=this.authServiceProvider.getData("userbyid/40").subscribe( myData => {
console.log(myData.username);
this.myAccountData=myData;
this.myAccountData.username=this.capitalizeFirstLetter(this.myAccountData.username);
});
}
async callhim():Promise<any>{
try {
const res = await this.call.callNumber("0557123656", true);
console.log(res);
} catch (err) {
console.log(err);
}
}
capitalizeFirstLetter(string) {
return string.charAt(0).toUpperCase() + string.slice(1);
}
selectedInfo(){
this.showInfoPers=true;
this.showMetiers=false;
this.showServices=false;
this.colorInfo="#3f4996";
this.colorMetiers="#fff";
this.colorServices="#fff";
this.changeDetectorRef.detectChanges();
}
selectedMetiers(){
this.showInfoPers=false;
this.showMetiers=true;
this.showServices=false;
this.colorInfo="#fff";
this.colorMetiers="#3f4996";
this.colorServices="#fff";
this.changeDetectorRef.detectChanges();
}
selectedServices(){
this.showInfoPers=false;
this.showMetiers=false;
this.showServices=true;
this.colorInfo="#fff";
this.colorMetiers="#fff";
this.colorServices="#3f4996";
this.changeDetectorRef.detectChanges();
}
}
我在使用 callhim 函数的部分评论了完整的profil.html页面：

但不知怎的，它在这里不起作用的是错误日志：

您在方法中使用async await。您无需添加.then and .catch already.
async callhim(): Promise<any> {
try {
const res = await this.call.callNumber("0557123656", true);
console.log(res);
} catch (err) {
console.log(err);
}
}
