Toggle icons in a selected row

Working stacklitz - https://stackblitz.com/edit/github-rlkrzv?file=src/app/play-list-page/play-list-page.component.html

Im trying to toggle between play and pause icons of a selected row, but when a song starts playing, the whole table gets a "pause" icon (examples below).

Highlighting a specific row works fine, toggle between play and pause functions and icons also,

its just toggling the icons in the selected row..

                            <img src="../assets/play_line_icon.png" class="playBtn" (click)="togglePlaystateSong(song.track_id,i);

    visibility: visible;
    width: 19.98px;
    height: 20px;
    padding-top: 3px;

Much appreciated!

Solution

  • You are showing the pause picture for every song, you need to make sure you are only showing it for the selected item, make the following change in your template:

    <td *ngIf="isPlaying">
   <img
       src="../assets/pause_line_icon.png"
       class="pauseBtn"
       (click)="togglePlaystateSong(song.track_id,i);getSongInfo(song);setClickedRow(i)"
       id="imgClickAndChange"
       *ngIf="selectedRow === i"
   />
</td>

    the change is adding *ngIf="selectedRow === i" on the img
