Is there a way to bind an onFocus Event to a TextField in NativeScript?

Apparently I can't find a focus event handler in NativeScript's documentation or API reference of TextFields elements. Am I wrong?

Or, is there a way to introduce the onFocus event extending the existing Nativescript's element?

(I am using typescript without Angular 2)

A PR for adding focus is pending review. Won't be long before you can use it on TextField and TextView elements!

You can use the on method that is mentioned here. I don't know if this is what you are looking for but here is an example:

In XML:

<TextView id="textfield" textWrap="true" tap="textfieldTap"/>

In js file:

var myTextfield = page.getViewById("textfield");

myTextfield.on("tap", function() {
    console.log("Hello from the other side");
});

Also, there is another way to listen to focus event on TextField. As we have the tap="textfieldTap"inside the XML TextField tag, then we can declare a function in the js to listen to that event:

function textfieldTap(args) {
    console.log("Textfield tap " + args.text);
}
exports.textfieldTap = textfieldTap;
