我有两个CSS类名如下
.icon_heart{颜色:#bdbdbd;}.icon_heart_red{颜色:#a6b7d4;;}
我的 HTML 有一个心形图标
<div class="icon_heart" *ngIf="showheartIcon">
这里我有两个 div 标签,心形图标最初是灰色,点击后我会将其更改为蓝色.
这是我的 ts 文件代码:
showheartIcon=true;showheartIconRed =假;setWishlistTrue(id){this.showheartIconRed = true;this.showheartIcon = false;}setWishlistFalse(id){this.showheartIconRed = false;this.showheartIcon = true;}
我有两个不同颜色的图标.
是否可以更改图标的类别而不是两个心形图标?
我在 JavaScript 中看到我们可以更改它w3schools 简单的方法将类应用于 div 标签,但我是 TypeScript 的新手.如何更改班级?
或
<div [ngClass]="showheartIconRead ? 'icon_heart_red' : 'icon_heart'">
I have two CSS class name as follows
.icon_heart{
color: #bdbdbd;
}
.icon_heart_red{
color:#a6b7d4;;
}
My HTML has a heart icon
<div class="icon_heart" *ngIf="showheartIcon">
<ion-icon name="heart" (click)="setWishlistTrue(category.product_id);" class="heart"></ion-icon>
</div>
<div class="icon_heart_red" *ngIf="showheartIconRed">
<ion-icon name="heart" (click)="setWishlistFalse(category.product_id);" class="heart"></ion-icon>
</div>
Here I have two div tags, the heart icon is of gray color initially and on clicking that I will change it to blue color.
Here is my ts file code:
showheartIcon=true;
showheartIconRed =false;
setWishlistTrue(id){
this.showheartIconRed = true;
this.showheartIcon = false;
}
setWishlistFalse(id){
this.showheartIconRed = false;
this.showheartIcon = true;
}
I have two icons of different color.
Question
Instead of having two heart icons is it possible to change the class of the icon?
I have seen in JavaScript we can change it w3schools simple way to apply class to the div tag, but I am new to TypeScript. How can I change the class?
解决方案 <div
[class.icon_heart]="!showheartIconRead"
[class.icon_heart_red]="showheartIconRead">
or
<div [ngClass]="showheartIconRead ? 'icon_heart_red' : 'icon_heart'">
