angularjs – ng-repeat中的Angular-js文件上传

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：UploadController
单击上传后,我用它来获取文件名

var json = JSON.stringify($scope.finalJson.comments);
        的console.log(JSON);

截图：

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得第二个文件名.任何人都可以建议我,如何在上传点击后立即获取多个文件.

}]

解决方法

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>

控制器代码：

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);
    };

}]);
