我在一个电子商务应用程序中工作,在这里我有购物车图标。我想做的是当我点击购物车图标,我想显示一个模式屏幕与用户选择的产品数据。
但在我的例子中,第一次在页面加载之后,模式屏幕在双击之后打开,然后它在单击之后打开。
偶像:
<i class="fas fa-cart-plus fa-flip-horizontal text-primary" (click)="get_My_Cart($event)" data-toggle="modal" data-target="#exampleModal" style="font-size:25px;cursor: pointer;"></i>
情态动词:
<div *ngIf="mycart && mycart.length" class="modal fade modalstyle" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header headerHeight text-white " style="background:rgb(0, 0, 0);font-weight:bold">
<h6 class="modal-title" id="exampleModalLabel">My Cart Items</h6>
<button #closeModalBtn type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<div *ngFor="let products of mycart;let i =index;">
<div class="container col-sm-12">
<div class="row">
<div class="col-sm-4 paddingforimage">
<img [src]="products['ITEM_IMAGE_PATH']">
</div>
<div class="text-info col-sm-6">
<span>
<h6>{{products?.TOTAL_QTY}} × {{products?.ITEM_PRICE}} ₹</h6>
</span>
<span>
<h6>{{products?.ITEM_DESC}}</h6>
</span>
<span>
<h6>{{products?.TOTAL_AMT}} ₹</h6>
</span>
</div>
<div class="col-sm-1 text-right">
<button type="button" class="close closebtn" aria-label="Close" (click)="detele_My_Cart(products?.ITEM_CODE)">
<span aria-hidden="true" (click)="detele_My_Cart(products?.ITEM_CODE)">×</span>
</button>
</div>
</div>
</div>
<hr>
</div>
<div class=" container row col-sm-12">
<div class="col-sm-6">
<strong>SHIPPING</strong>
</div>
<div class="col-sm-6 text-right">0 ₹</div>
<hr>
<div class="col-sm-6">
<strong>TOTAL</strong>
</div>
<div class="col-sm-6 text-right">{{my_Cart_Total_Amount}} ₹</div>
</div>
<br>
<div class="container row col-sm-12" id="wrapper">
<button type="button" class="btn btn-success buttonSize" data-dismiss="modal" routerLink="/cartsummary">
<strong>CHECK OUT</strong>
</button>
</div>
</div>
</div>
</div>
</div>
组成部分:
get_My_Cart($event) {
this.publicIp.v4().then(ip => {
this.CartdataService.get_My_Cart_Products(ip).subscribe(
data => {
this.mycart = data['Table']
this.my_Cart_Total_Amount = data['Table1'][0]['TOTAL_AMOUNT']
});
});
}
在模态屏幕我有一个验证,模态屏幕是打开的,如果数据是绑定在它否则它不会。(模态不会打开,如果购物车是空的)。
*ngIf="mycart && mycart.length"
如果我将此验证从模式屏幕中删除,它将正常工作,但始终打开(如果购物车中没有产品,并且用户单击了购物车图标,它将打开,但我要限制它)。
有人能告诉我怎么处理这个问题吗..
