AngularJS - loading and displaying an image using the FileReader API (multiple files)

I use the following example: it works fine, but I would like to upload multiple images at once.

http://jsfiddle.net/kkhxsgLu/2/

<div ng-controller="MyCtrl">

<div ng-repeat="step in stepsModel">
    <img class="thumb" ng-src="{{step}}" />
</div>

<input type='file' ng-model-instant onchange="angular.element(this).scope().imageUpload(this)" />


 $scope.stepsModel = [];

$scope.imageUpload = function(element){
    var reader = new FileReader();
    reader.onload = $scope.imageIsLoaded;
    reader.readAsDataURL(element.files[0]);
}

$scope.imageIsLoaded = function(e){
    $scope.$apply(function() {
        $scope.stepsModel.push(e.target.result);
    });
}

Thanks, kindly help me, I started with angularjs

<div ng-controller="MyCtrl">

<div ng-repeat="step in stepsModel">
    <img class="thumb" ng-src="{{step}}" />
</div>

<input type='file' ng-model-instant 
       onchange="angular.element(this).scope().imageUpload(event)"
       multiple />


$scope.stepsModel = [];

$scope.imageUpload = function(event){
     var files = event.target.files; //FileList object

     for (var i = 0; i < files.length; i++) {
         var file = files[i];
             var reader = new FileReader();
             reader.onload = $scope.imageIsLoaded; 
             reader.readAsDataURL(file);
     }
}

$scope.imageIsLoaded = function(e){
    $scope.$apply(function() {
        $scope.stepsModel.push(e.target.result);
    });
}

Zypps987, try using the var file = [0] file rather than inside the loop.

ng-model ( )

<input>, AngularJS, <input type=file>. .

<input type="file" files-input ng-model="fileArray" multiple>

files-input:

angular.module("app").directive("filesInput", function() {
  return {
    require: "ngModel",
    link: function postLink(scope,elem,attrs,ngModel) {
      elem.on("change", function(e) {
        var files = elem[0].files;
        ngModel.$setViewValue(files);
      })
    }
  }
})

The above directive adds a change listener, which updates the model using the element's file property input.

This directive allows you to <input type=file>automatically work with directives ng-changeand ng-form.

Inline Demo files-inputDirective

angular.module("app",[]);

angular.module("app").directive("filesInput", function() {
  return {
    require: "ngModel",
    link: function postLink(scope,elem,attrs,ngModel) {
      elem.on("change", function(e) {
        var files = elem[0].files;
        ngModel.$setViewValue(files);
      })
    }
  }
});
<script src="//unpkg.com/angular/angular.js"></script>
  <body ng-app="app">
    <h1>AngularJS Input `type=file` Demo</h1>
    
    <input type="file" files-input ng-model="fileArray" multiple>
    
    <h2>Files</h2>
    <div ng-repeat="file in fileArray">
