How to set focus on element with binding?

Question

In Angular2 how can I set binding on element focus. I don\'t want to set it with elementRef. I think in AngularJS there is ngFocus directive In Angular2 there is no such dir

Answer 1

Renderer service is now deprecated (as of Angular 4.x) The new Renderer2 service doesn't have the invokeElementMethod. What you can do is to get a reference to the element like this:

const element = this.renderer.selectRootElement('#elementId');

And then you can use that to focus on that element like so:

element.focus();

More on how selectRootElement works here:

EDIT:

If the element doesn't get focused the common issue is that the element is not ready. (eg.: disabled, hidden etc.). You can do this:

setTimeout(() => element.focus(), 0);

This will create a macrotask that will run in the next VM turn, so if you enabled the element the focus will run properly.
