In HTML page
<h2 class="entry-title"><a href="javascript:void(0)" (click)="moreInfo(fashion)">{{fashion.postName}}</a></h2>
In Component.ts
moreInfo(data) {
    this.router.navigate(['/blog-info/', data.postName]);
  }
In HTML page
<h2 class="entry-title"><a href="javascript:void(0)" (click)="moreInfo(fashion)">{{fashion.postName}}</a></h2>
In Component.ts
moreInfo(data) {
    this.router.navigate(['/blog-info/', data.postName]);
  }
 
    
     
    
    you need to add target attribute in your HTML
<h2 class="entry-title"><a target="_blank" href="javascript:void(0)" (click)="moreInfo(fashion)">your template expression</a></h2>
 
    
    If you want to do it, you should have href attribute. So, routerLink is a good choice. other way:
<h2 class="entry-title"><a href="/blog-info/{{fashion.postName}}" (click)="moreInfo($event, fashion)">{{fashion.postName}}</a></h2>
moreInfo(event, data) {
    event.preventDefault();
    this.router.navigate(['/blog-info/', data.postName]);
}
 
    
    Call function in routerLink. create function in component:
moreInfo(data) {
     return  data.postName.replace(/\s/g, '-') + '-' + data._id;
  }
Use like this in routerLink:
[routerLink]="['/blog-info', moreInfo(fashion)]"
