The ng-model directive does not work with <button> elements:
<button id="submitBtn" type="submit" ng-click="upload()"
̶n̶g̶-̶m̶o̶d̶e̶l̶=̶"̶u̶p̶l̶o̶a̶d̶B̶t̶n̶"̶ >Upload</button>
Simply assign a function to $scope.upload:
var app = angular.module('myApp', [])
app.controller('appCtrl', function ($scope, $rootScope, $http, fileUploadService){
̶$̶s̶c̶o̶p̶e̶.̶$̶w̶a̶t̶c̶h̶(̶'̶u̶p̶l̶o̶a̶d̶B̶t̶n̶'̶,̶ ̶f̶u̶n̶c̶t̶i̶o̶n̶ ̶(̶n̶e̶w̶V̶a̶l̶,̶ ̶o̶l̶d̶V̶a̶l̶)̶ ̶{̶
̶v̶a̶r̶ ̶s̶u̶b̶m̶i̶t̶B̶t̶n̶ ̶=̶ ̶d̶o̶c̶u̶m̶e̶n̶t̶.̶g̶e̶t̶E̶l̶e̶m̶e̶n̶t̶B̶y̶I̶d̶(̶'̶s̶u̶b̶m̶i̶t̶B̶t̶n̶'̶)̶;̶
̶$̶s̶c̶o̶p̶e̶.̶u̶p̶l̶o̶a̶d̶ ̶=̶ ̶f̶u̶n̶c̶t̶i̶o̶n̶(̶)̶ ̶{̶
̶i̶f̶(̶n̶e̶w̶V̶a̶l̶ ̶=̶=̶ ̶t̶r̶u̶e̶)̶{̶
$scope.upload = function() {
var file = $scope.uploadedFile;
console.log('file is ' );
console.dir(file);
//...
};
//...
})
The console.log statements will show upon clicking the button.
