Question

我想在对象中使用翻译来在Ionic 2上使用toast。但我不明白如何在.ts文件中使用ng2-translate ... Somenone能给我一个例子吗？

我想在菜单中的标题中翻译。我尝试这样但它不起作用：

constructor(public platform: Platform, public menu: MenuController, public translate : TranslateService) {
this.initializeApp();

translate.setDefaultLang('fr');
translate.use('fr');
let testTrad : string = 'Accueil';

translate.get('TEST').subscribe(res => {testTrad = res; console.log(testTrad)});
console.log(testTrad);

// Remplissage du tableau des pages.
this.pages= [
  {title: testTrad ,                  component: TabsPage},
  {title: 'Mon compte',               component: MyAccountPage},
  {title: 'Changer de mot de passe' , component: ChangePasswordPage},
  {title: 'Documents' ,               component: DocumentsPage}
]

必须在我的菜单上显示“test”，但它会继续显示“Accueil”。

没错，

translate.get('TEST').subscribe(res => {testTrad = res; console.log(testTrad)});
console.log(testTrad);

// Remplissage du tableau des pages.
this.pages= [
  {title: testTrad ,                  component: TabsPage},
  {title: 'Mon compte',               component: MyAccountPage},
  {title: 'Changer de mot de passe' , component: ChangePasswordPage},
  {title: 'Documents' ,               component: DocumentsPage}
]

.subscribe是异步的，因此 subscribe中指定的值}

尝试

translate.get('TEST').subscribe(res => {
    testTrad = res; 
    console.log(testTrad);
    this.pages= [
       {title: testTrad ,                  component: TabsPage},
       {title: 'Mon compte',               component: MyAccountPage},
       {title: 'Changer de mot de passe' , component: ChangePasswordPage},
       {title: 'Documents' ,               component: DocumentsPage}
    ]
});
console.log(testTrad);

或者，如果您不想等待完成异步，您可以尝试

this.pages= [
  {title: 'Mon compte',               component: MyAccountPage},
  {title: 'Changer de mot de passe' , component: ChangePasswordPage},
  {title: 'Documents' ,               component: DocumentsPage}
]
translate.get('TEST').subscribe(res => {
   testTrad = res;
   this.pages.push({title: testTrad, component: TabsPage});
 });
