TypeScript 2.x By Example

The enableAddTask function

This function is pretty simple; it will just set the property identifying that we are going to add a new task and set the focus on the input element as shown below.

enableAddtask() {     let input = this.el.nativeElement      .getElementsByClassName('add-task')[0]      .getElementsByTagName('input')[0];    setTimeout(function () { input.focus(); }, 0);  }
