以下是一个使用Angular 9动画来创建一个步进组件的解决方案,其中包含了代码示例:
StepperComponent
:import { Component, Input } from '@angular/core';
import { trigger, state, style, transition, animate } from '@angular/animations';
@Component({
selector: 'app-stepper',
templateUrl: './stepper.component.html',
styleUrls: ['./stepper.component.css'],
animations: [
trigger('stepAnimation', [
state('current', style({
transform: 'scale(1.2)',
backgroundColor: '#ffcc00'
})),
state('completed', style({
transform: 'scale(1)',
backgroundColor: '#00cc00'
})),
transition('current <=> completed', [
animate('200ms')
])
])
]
})
export class StepperComponent {
@Input() steps: number;
currentStep = 1;
goToStep(step: number) {
this.currentStep = step;
}
}
stepper.component.html
模板中添加步进组件的HTML结构和动画绑定:
step }" [@stepAnimation]="currentStep > step ? 'completed' : 'current'">
{{ step }}
stepper.component.css
样式文件中定义步进组件的样式:.stepper {
display: flex;
justify-content: space-between;
}
.step {
width: 30px;
height: 30px;
border-radius: 50%;
background-color: #cccccc;
display: flex;
justify-content: center;
align-items: center;
color: #ffffff;
font-weight: bold;
}
.current {
transform: scale(1.2);
background-color: #ffcc00;
}
.completed {
transform: scale(1);
background-color: #00cc00;
}
StepperComponent
并传递步数:
这是一个简单的步进组件示例,它会根据当前步骤的状态应用动画效果。您可以根据需要进行修改和扩展。
