Js code is:
var app = angular.module('myApp', []);
app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.files = [];
$scope.upload=function(){
alert($scope.files.length+" files selected ... Write your Upload Code");
};
});
app.directive('ngFileModel', ['$parse', function ($parse) {
return {
restrict: 'A',
link: function (scope, element, attrs) {
var model = $parse(attrs.ngFileModel);
var isMultiple = attrs.multiple;
var modelSetter = model.assign;
element.bind('change', function () {
var values = [];
angular.forEach(element[0].files, function (item) {
var value = {
// File Name
name: item.name,
//File Size
size: item.size,
//File URL to view
url: URL.createObjectURL(item),
// File Input Value
_file: item
};
values.push(value);
});
scope.$apply(function () {
if (isMultiple) {
modelSetter(scope, values);
} else {
modelSetter(scope, values[0]);
}
});
});
}
