angular's ng-init alternative in Angular 2

Question

What is the alternative of ng-init=\"myText=\'Hello World!\'\" in Angular 2 to add in the template, not in the component

Answer 1

You do not always need a custom directive for this. If you're okay with your function being called more than once, you can simple do:

The word "init" there is completely arbitrary. The downside is yourInitFunction will get called on every digest cycle.

Note, if you return anything from your function this will add an attribute called "init" to your element with the returned value. If you return undefined, it will not add the attribute.

This is normally a non-issue, just keep it in mind.
