Testing Durandal Viewmodel that makes http call
define(['plugins/http', 'plugins/dialog', 'durandal/app', 'viewmodels/locale', 'knockout'],
function (http, dialog, app, locale, ko) {
//Note: This module exports an object.
//That means that every module that "requires" it will get the same object instance.
//If you wish to be able to create multiple instances, instead export a function.
//See the "welcome" module for an example of function export.

Last active December 11, 2015 20:48
A custom binding for KnockoutJS allowing you hook into the onbeforeunload event on the window. This will allow you to display a message to the user when navigating away from or closing the page, reminding the user to save their work, etc.
// Author: Tim Larson @codethug
ko.bindingHandlers.beforeUnloadText = {
init: function(element, valueAccessor, allBindingsAccessor, viewModel) {
if (window.onbeforeunload == null) {
window.onbeforeunload = function(){
var value = valueAccessor();
var promptText = ko.utils.unwrapObservable(value);
if (typeof promptText == "undefined" || promptText == null) {
// Return nothing. This will cause the prompt not to appear
} else {
