    this.meta
      .getToken(
        "images",
        this.imgName.ReportJobId,
        (folder == "input" ?
          this.imgName.UniquePhotoName :
          this.imgName.UniquePhotoName
            .replace(".JPG", ".png")
            .replace(".jpg", ".png")),
        folder
      )
      .subscribe(data => {
        this.imgSrc = this.someurl(data);
      }, () => {
        this.imgSrc = "assets/images/image.jpg";
      });
  }

<ul class="result__image--tabslist">
            <li class="result__image--tab left left__tab" (click)="loadImg('output')">
                <span class="result__tab--txt" [ngClass]="toggleClick?'selected':''">
                    Scan
                </span>
            </li>
            <li class="result__image--tab left" (click)="loadImg('input')">
                <span class="result__tab--txt" [ngClass]="toggleClick?'':'selected'">
                    Original

You can try with

[class.selected]="toggleClick"

instead of

[ngClass]="toggleClick?'':'selected'"

This way the selected class is applied only if toggleClick is true.

Hi. style is not changing. both are displaying as selected. – DharamChauhan Sep 25 '19 at 11:15
You put the same class directive on both images. Of course they both have `selected` class. – mbojko Sep 25 '19 at 11:28

You can try:

[class]="toggleClick?'selected':''"

or,

[ngClass]="{'selected': toggleClick}"

or,

[class.selected]="toggleClick"
