Angular动态切换css元素样式

第一种方式，切换不同的css

step1: D:\vue\untitled3\src\app\app.component.css

.show-true {
  background-color: red;
  color: white;
}

.show-false {
  color: white;
  background-color: blue;
}

step2: D:\vue\untitled3\src\app\app.component.html

<html>
<head></head>
<body>
<div >
  <span class="show-{{temp}}">test</span>
  <button (click)="getData()">切换背景颜色</button>
</div>
</body>
</html>

step3: D:\vue\untitled3\src\app\app.component.ts

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'untitled3';
  temp:boolean=false;

  getData(){
    if (this.temp){
      this.temp = false;
    }else{
      this.temp = true;
    }
  }
}

end
