Basic blur event in a Telerik Nativescript Mobile App

Question

I am writing a cross-platform mobile app using Telerik AppBuilder with NativeScript. I am going nuts trying to figure out how to get a basic \"blur\" or \"onTextChanged\" event

Answer 1

In nativescript 3+ this is how I catch blur events.

The sample code is in nativescript (core)

example.js

const view = require("ui/core/view");
const textFieldModule = require("ui/text-field");

exports.pageLoaded = (args) => {
  let page = args.object;
  let myTextFieldView = view.getViewById(page, "myTextField");
  myTextFieldView.on(textFieldModule.TextField.blurEvent, function(eventData) {
      console.log('blur event triggered');
  }, this);
}
