我正在使用laravel中的API从事Ionic电子商务项目,但问题是,我已经创建了一个愿望清单按钮,当我单击单个产品上的愿望清单按钮时,它将单击所有愿望清单按钮。
这是我的 productdetails.html :
<ion-header>
<ion-navbar>
<ion-title>Products</ion-title>
</ion-navbar>
</ion-header>
<ion-content padding>
<ion-row align-items-center justify-content-center class="mynewr11">
<ion-col *ngFor="let product of this.pdeta" col-5 class="mynewcol22">
<img class="myimg11" src="{{product.image}}" />
<p>{{ product.product_name }}</p>
<p><strong>Price:</strong> ₹{{ product.product_actual_price * product?.count }}</p>
<ion-col class="qty">
<button (click)="decreaseProductCount(product)" clear ion-button small color="dark" class="mynewbtn11">
-
</button>
<button ion-button small clear color="dark" class="mynewbtn11">
{{product?.count}}
</button>
<button (click)="incrementProductCount(product)" clear ion-button small color="dark" class="mynewbtn11">
+
</button>
</ion-col>
<button class="mybtn11" (click)="addToCart(product)" ion-button small>
Add to Cart
</button>
<button ion-button icon-only class="wish-list-btn card" *ngIf="!heart_clicked" (click)="addtoWishlist(true,product)" color="light" class="mywisbtn11">
<ion-icon name="heart-outline"></ion-icon>
</button>
<button ion-button icon-only class="wish-list-btn card" *ngIf="heart_clicked" (click)="addtoWishlist(false,product)" color="light" class="mywisbtn11">
<ion-icon name="ios-heart"></ion-icon>
</button>
</ion-col>
</ion-row>
</ion-content>
在此html中,我将显示所有产品。
这是我的 productdetails.ts :
import { Component } from '@angular/core';
import { IonicPage, NavController, NavParams, ToastController } from 'ionic-angular';
import { CartProvider } from '../../providers/cart/cart';
import { CartPage } from '../cart/cart';
@IonicPage()
@Component({
selector: 'page-productdetails',
templateUrl: 'productdetails.html',
})
export class ProductdetailsPage {
heart_clicked: boolean = false;
constructor(public navCtrl: NavController, public navParams: NavParams, private cartService: CartProvider, public toastCtrl: ToastController)
{}
decreaseProductCount(product) {
if(typeof product.count === 'undefined') {
product.count = 1;
}
if (product.count > 1) {
product.count--;
}
}
incrementProductCount(product) {
if(typeof product.count === 'undefined') {
product.count = 1;
}
product.count++;
}
addtoWishlist(a,product){
if(a==true){
this.heart_clicked=true;
}else
{
this.heart_clicked=false;
}
}
}
在这张照片中,当我单击一个愿望清单按钮时,它将检查所有愿望清单按钮。非常感谢您的帮助。

根据相同的组件变量heart_clicked
,将显示页面上所有的愿望清单按钮。
<button ion-button icon-only class="wish-list-btn card" *ngIf="!heart_clicked" (click)="addtoWishlist(true,product)" color="light" class="mywisbtn11">
<ion-icon name="heart-outline"></ion-icon>
</button>
<button ion-button icon-only class="wish-list-btn card" *ngIf="heart_clicked" (click)="addtoWishlist(false,product)" color="light" class="mywisbtn11">
<ion-icon name="ios-heart"></ion-icon>
</button>
单击任何愿望清单按钮时,将调用函数addtoWishlist()
,该函数将相应地设置变量heart_clicked
。
heart_clicked: boolean = false;
addtoWishlist(a,product){
if(a==true){
this.heart_clicked=true;
}else
{
this.heart_clicked=false;
}
}
由于您所有的愿望清单html图标都指定了*ngIf="heart_clicked"
或*ngIf="!heart_clicked"
,因此它们都依赖于相同的组件范围变量。
您可以将heart_clicked
变量添加到product
中,以便每个产品的愿望清单按钮都具有自己的变量product.heart_clicked
。
然后我将product.heart_clicked
重命名为product.onWishlist
并根据该变量设置要显示的图标。然后,您只需在模板中一个按钮即可。
<button ion-button icon-only class="wish-list-btn card" (click)="toggleOnWishlist(product)" color="light" class="mywisbtn11">
<ion-icon [name]="product.onWishlist ? 'ios-heart' : 'heart-outline'"></ion-icon>
</button>
toggleOnWishlist(product){
product.onWishlist = !product.onWishlist;
}
