Modifying the name of a file upload in AngularJS

Modifying the name of a file upload in AngularJS

Does anyone know a way to dynamically change the file name in AngularJS?

<input type="file" onchange="angular.element(this).scope().filename(this)">

In the filename method, I am attempting to change the file name but the value is not updating. How can I successfully change the file name in a file upload?

$scope.filename= function(e)
{

 for (var i = 0; i < e.files.length; i++) {

 var x =  e.files[i].name + "test";
 e.files[i].name =  x;
 /// I am altering the file name here, but it seems to be a read-only property. How can I change the name?
  }
}

I need to change the upload file name for each uploaded file. How can I assign a file name to every file that is uploaded?

Check out this AngularJS snippet:

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
  $scope.modifyFileName = function(e) {
    for (var i = 0; i < e.files.length; i++) {

      var newFileName = e.files[i].name.split('.')[0] + "test." + e.files[i].name.split('.')[1];
      console.log(newFileName);
      e.files[i].name = newFileName;

    }
  }

});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app="myApp" ng-controller="myCtrl">

  <input type="file" onchange="angular.element(this).scope().modifyFileName(this)">

</div>

When working with angularJS, it's possible to utilize a directive in order to alter the file name.

.directive('fileName', function() {
  return {
    scope: {
      fileName: '='
    },
    link: function(scope, el, attrs) {
      el.bind('change', function(event) {
        var files = event.target.files;
        var file = files[0];
        scope.file = 'Newname';
        scope.$apply();
      });
    }
  };
});

You can implement the directive by including it within the element.

<input type="file" file-name="fileName">{{fileName}}

When dealing with a readonly value, you can utilize a directive to change the file name. Take a look at the following code snippet:

var module = angular.module('myApp', []);
module.directive('file', function() {
  return {
    scope: {
      file: '='
    },
    link: function(scope, element, attrs) {
      element.bind('change', function(event) {
        var files = event.target.files;
        var file = files[0];
        scope.file = file.name.split('.')[0] + "_test." + file.name.split('.')[1];
        scope.$apply();
      });
    }
  };
});

function MainController($scope) {
  $scope.file = {};
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MainController">
  <input type="file" data-file="file.file" />
  <div>Update File Name: {{file.file}}</div>

</div>
