angularjs - 在 ng-repeat 中上传 Angular-js 文件

Question

我的 html 文件:Upload.html

<tr ng-repeat="expenses in finalJson.comments">
 <td >
   <div class="image-upload">
     <label for="file-input"> 
      <img src="../images/upload1.jpg" style="width: 20px;"/>{{data.files[0].name}} 
    </label>
     <input id="file-input" type="file" ng-model="expenses.files"  ngf-select accept="*" value=""/>
    </div>
 </td>
</tr>

Controller :上传 Controller
单击上传后，我已使用它来获取文件名

var json = JSON.stringify($scope.finalJson.comments);
控制台日志(json)；

截屏:



当我上传一个文件的工作文件时，当我添加多个文件时，我无法在控制台中获取第二个文件名。任何人都可以建议我，如何在点击上传后一次获取多个文件。

[{
    "index": 1,
    "amount": "10",
    "$$hashKey": "object:5",
    "date": "2016-04-11",

    "note": "wdxw",
    "paid_to": "swdw",
    "files": {
        "webkitRelativePath": "",

在 ng-repeat 中使用此代码

html代码:

<div ng-controller = "myCtrl">
    <div ng-repeat="fileInput in fileInputs">
        <input type="file" file-model="{{'myFile' + $index}}"/>
        <button ng-click="uploadFile('myFile' + $index)">upload me</button>
    </div>
</div>

Controller 代码:

var myApp = angular.module('myApp', []);

myApp.directive('fileModel', ['$parse', function ($parse) {
    return {
        restrict: 'A',
        link: function(scope, element, attrs) {
            var model, modelSetter;

            attrs.$observe('fileModel', function(fileModel){
                model = $parse(attrs.fileModel);
                modelSetter = model.assign;
            });

            element.bind('change', function(){
                scope.$apply(function(){
                    modelSetter(scope.$parent, element[0].files[0]);
                });
            });
        }
    };
}]);

myApp.service('fileUpload', ['$http', function ($http) {
    this.uploadFileToUrl = function(file, uploadUrl){
        var fd = new FormData();
        fd.append('file', file);
        $http.post(uploadUrl, fd, {
            transformRequest: angular.identity,
            headers: {'Content-Type': undefined}
        })
        .success(function(){
        })
        .error(function(){
        });
    }
}]);

myApp.controller('myCtrl', ['$scope', 'fileUpload', function($scope, fileUpload){
    $scope.fileInputs = [1,2,3];
    $scope.uploadFile = function(filename){
        var file = $scope[filename];
        console.log('file is ' + JSON.stringify(file));
        console.dir(file);
        var uploadUrl = "http://httpbin.org/post";
        fileUpload.uploadFileToUrl(file, uploadUrl);
    };

}]);
