实现 angular-uploadcare 模块，可在此处找到。
似乎有效，但 Chrome 给出了第 34 行 $parse undefined 错误。如何解决这个问题？
我已经粘贴了下面的代码。
/**
* @ngdoc directive
* @name angular-uploadcare.directive:Uploadcare
* @description Provides a directive for the Uploadcare widget.
* # Uploadcare
*/
angular.module('ng-uploadcare', [])
.directive('uploadcareWidget', function () {
return {
restrict: 'E',
replace: true,
require: 'ngModel',
template: '<input type="hidden" role="ng-uploadcare-uploader" />',
scope: {
onWidgetReady: '&',
onUploadComplete: '&',
onChange: '&',
},
controller: ['$scope', '$element', '$log', function($scope, $element, $log) {
if(!uploadcare) {
$log.error('Uploadcare script has not been loaded!.');
return;
}
$scope.widget = uploadcare.Widget($element);
$scope.onWidgetReady({widget: $scope.widget});
$scope.widget.onUploadComplete(function(info) {
$scope.onUploadComplete({info: info});
});
$scope.widget.onChange(function(file) {
// add data binding for hidden inputs
$scope.$apply(function () {
$parse($attrs.ngModel).assign($scope.$parent, $element.val());
});
$scope.onChange({file: file});
})
}]
};
});
