我正在使用Ionic 3并在我的主页上,我有以下代码。当我单击searchMore按钮时,它会导航到新页面。我想在新页面的h5中加入“Cook With My Pantry”。
<ion-grid>
<ion-row>
<ion-col col-9>
<h5 name="cookWith">Cook With What is in My Pantry</h5>
</ion-col>
<div class="applyMore">
<ion-col col-3>
<button (click)="searchMore()" ion-button clear icon-left>
More
<ion-icon name='arrow-forward'></ion-icon>
</button>
</ion-col>
</div>
</ion-row>
</ion-grid>
在它链接到的页面上,我有以下代码,我希望h5出现。
<h5 name="cookWith">{{cookWith}}</h5>
在我的.TS文件中,我有以下
来自主页
export class HomePage {constructor(public navCtrl: NavController,
public navParams:
NavParams) {
}
/**
*links filter button to FilterPage
*/
recipeFilter(event, button) {
this.navCtrl.push(FilterPage, {
button: button
});
}
searchMore(event, button) {
this.navCtrl.push(RecipesearchPage, {
});
;
}
}
链接到
的页面export class RecipesearchPage {
constructor(public navCtrl: NavController, public navParams:
NavParams) {
}
ionViewDidLoad() {
console.log('ionViewDidLoad RecipesearchPage');
}
/**
*on click, links from recipe card to individual recipe page
*/
individualRecipe() {
this.navCtrl.push(RecipePage);
};
}

所以我认为你可以这样做。如果以后需要更改字符串,可以在构造函数中更改它。我认为如果它是静态的并且不会改变为什么不在两个地方都有它?
<ion-grid>
<ion-row>
<ion-col col-9>
<h5>{{cookWith}}</h5>
</ion-col>
<div class="applyMore">
<ion-col col-3>
<button (click)="searchMore()" ion-button clear icon-left>
More
<ion-icon name='arrow-forward'></ion-icon>
</button>
</ion-col>
</div>
</ion-row>
</ion-grid>
在主要组件类中添加值的声明:
export class HomePage {
cookWith: string;
constructor(
public navCtrl: NavController,
public navParams: NavParams
){
this.cookWith = 'Cook With What is in My Pantry';
}
/**
*links filter button to FilterPage
*/
recipeFilter(event, button) {
this.navCtrl.push(FilterPage, {
button: button
});
}
searchMore(event, button) {
this.navCtrl.push(RecipesearchPage, {
cookWith: this.cookWith
});
}
}
然后你在另一边拿起它:
export class RecipesearchPage {
cookWith: string;
constructor(
public navCtrl: NavController,
public navParams: NavParams
){
this.cookWith = navParams.get('cookWith');
}
ionViewDidLoad() {
console.log('ionViewDidLoad RecipesearchPage');
}
/**
*on click, links from recipe card to individual recipe page
*/
individualRecipe() {
this.navCtrl.push(RecipePage);
};
}
<h5>Cook With What is in My Pantry</h5>

在ionic / angular的多个页面中重用同一页眉的最佳方法是通过directive
