Check if router.url contains specific string?

You can use LocationStrategy to get url without parameters.

import {LocationStrategy} from '@angular/common';


export class AppComponent implements OnInit {

    constructor(private url:LocationStrategy) { }

    ngOnInit() {

        console.log(this.url.path());
        if(this.url.path()==='/test/sort'){

         this.active=0; 
         }

    }

}

You can also use:

if (this.router.url.includes('/test/sort')) 
{  
     this.active = 0; 
}

Method String.includes(searchString: string, position?: number): boolean - Returns true if searchString appears as a substring of the result of converting this object to a String, at one or more positions that are greater than or equal to position; otherwise, returns false.

If you want something basic that works:

if (this.router.url.indexOf('/test/sort') > -1) {
  this.active = 0;
}
