Angular: How to render HTML from a .ts file?

Question

I used jQuery dataTable for display data on list view. And I tried to bind data to dataTable using following way.

On users.component.ts

getUsers() {
    this.UserService.getUsersList()
        .subscribe(
        success => {
            this.userList = success;
            $("#userTable").find('tbody').empty();
            var dataClaims = this.userList;
            for (let i = 0; i < dataClaims.length; i++) {
                $('#userTable').dataTable().fnAddData([
                    (i + 1),
                    dataClaims[i].name,
                    dataClaims[i].email,
                    dataClaims[i].contact_number,
                    dataClaims[i].address,
                    '<a [routerLink]="[' +"'"+"../../user/update" +"'" +']"' + ' class="fa fa-1x fa-pencil-square-o"></a>',
                ]);
            }
        }
        );
} 

Above function is working properly and dataTable is working without issue.

But [routerLink] is not converted to html. On the output it is displayed following way,

<a [routerlink]="['../../user/update']" class="fa fa-1x fa-pencil-square-o"></a>

But it should be converted to following way,

<a _ngcontent-c0="" ng-reflect-router-link="user/update" href="/user/update" class="fa fa-1x fa-pencil-square-o"></a>

Could someone please explain how to convert [routerlink] to normal link when render html data from a .ts file. Thank you.

If you really want to use dataTable, maybe this can be helpful for you:

Basically you should create an Directive that encapsulate your dataTable logic.

import {Directive, ElementRef} from '@angular/core';
import {Input, OnInit}         from '@angular/core';


import { JqueryDataTableEvent } from './jquery-datable-event';
import 'jquery.dataTables';

declare var jQuery:any;

@Directive({
    selector: '[jqueryDatatable]'
})

export class JqueryDatatableDirective implements OnInit {
    private _datatable : any;

    @Input()
    jqueryDatatable: any;

    @Input()
    dataTableEvents: JqueryDataTableEvent[];

    constructor(private _element: ElementRef) {}

    ngOnInit() {
        this.applyOptions();
        this.applyEvents();
    }

    applyOptions()
    {
        if (!this.jqueryDatatable)
            console.error("Empty options array was passed to initialize jqueryDatatable.");

        this._datatable = jQuery(this._element.nativeElement).DataTable( this.jqueryDatatable || {} );

    }

    applyEvents() {
        this.dataTableEvents.map((event)=> {
            this._datatable.on(event.eventName, event.selector, event.callback)
        });
    }
}

[routerLink] doesn't work. You need to use innerHTML functionality.

ts file:-

 tool = '<a href="../../user/update" class="fa fa-1x fa-pencil-square-o">View</a>';

html file:-

<div [innerHTML]="tool"></div>

Output:-

<div _ngcontent-c1=""><a href="../../user/update" class="fa fa-1x fa-pencil-square-o">View</a></div>

Could you please explain that using my code sample.

Even if you use DomSanitizer, it still does not compile it through Angular.

The OP wanted routerLink and not innerHTML.

Seems not to work. Testet it with a small example. The innerHTML prop isnt doing anything.
