JavaScript

// define app, include Wijmo 5 directives
var app = angular.module('app', ['wj']);

// controller
app.controller('appCtrl', function($scope) {

  // create some random data
  var countries = 'United States of America asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf,Germany,UK,Japan,Italy,Greece'.split(',');
  var data = [];
  var testvar = "asdf asdf asdf asdf asdf asdf asdf asdf asdf ";
  for (var i = 0; i < countries.length; i++) {
    data.push({
      country: countries[i],
      downloads: Math.round(Math.random() * 20000),
      sales: Math.random() * 10000,
      expenses: Math.random() * 5000
    });
    
  $scope.testBtn = function(a) {
    alert(a.country);
    alert(a.sales);
  };
    
  }

  // expose data as a CollectionView to get events
  $scope.data = new wijmo.collections.CollectionView(data);
