如何在角度2中单击更改锚标签文本 [英] How to change Anchor Tag text on Click in angular 2

问题描述

我必须在显示"和隐藏"之间切换文本.我该怎么做?我尝试了很多，但没有工作.我不想为此使用jQuery.我只想使用角度.谁能帮我这个??

I have to toggle the text On view and Hide How do i do that? I tried many but didnt work. I dont want to use Jquery for this. I want to use only angular. Can anyone help me with this??

<a  class="history-link view-history-class" id="show-view-address" (click)="view()" >View</a>

组件:

view : boolean ;
    view(){
            this.view = !this.view
        }

为此，当我单击视图时，它将切换一个表.然后，文本应更改为隐藏".单击隐藏时也一样.

For this when i click view It will toggle a table. Then the text should change to Hide. Same when i click hide.

推荐答案

import {Component, NgModule, VERSION} from '@angular/core'
import {BrowserModule} from '@angular/platform-browser'

@Component({
  selector: 'my-app',
  template: `
    <div>
      <a href = "#" (click) = "on()">{{value}}</a>
    </div>
  `,
})
export class App {

  value  = "View";
  toogle = true;

  on(val:boolean){
    //either this
    this.value = (!this.toogle)?"View":"Hide";
    this.toogle = !this.toogle;

    //or this
    this.value = (this.value == "View")?"Hide":"View"; // and remove toogle
  }

}

@NgModule({
  imports: [ BrowserModule ],
  declarations: [ App ],
  bootstrap: [ App ]
})
export class AppModule {}
