I'm looking for a solution to add a button read more and less in my long text with angular 5 or I need to convert this code with Js to angular 6:

readMoreButton.js:

$(document).ready(function(){
    $('.service-info').hide();
    $('.read-less').hide();
      $('.read-more').click(function(){
          $(this).hide();
          $(this).next().show();
          $(this).next().next().show();
        })
      $('.read-less').click(function(){
        $(this).prev().hide();
          $(this).prev().prev().show();
          $(this).hide();
      })
  })

How I achieved this

Step 1:

<button type="button" (click)="alterDescriptionText()">
   { showShortDesciption ? 'SHOW ALL': 'SHOW LESS' }}
 </button>

Step 2: (In Your .ponent.ts File)

 showShortDesciption = true

 alterDescriptionText() {
    this.showShortDesciption = !this.showShortDesciption
 }

Step 3:

<div [ngClass]="{'show-less': showShortDesciption}">
      <!-- Your Text Here -->
</div

Step 4:

.show-less {
    height: 4rem;
    overflow: hidden;
    padding: 1rem;
}

Basically i'm altering the height of div on button click

Try to use the angular plugin "@minni/read-more". Check out the link here. It's quite a simple and easy-to-use plugin.
