Question

我正在使用简单的文件上传代码。它显示错误：

这是我的代码：

$scope.uploadFile = function (files) {
        var form_data = new FormData();
        form_data.append("file", files[0]);
        $http.post('process.php', form_data, {
            transformRequest: angular.identity,
            headers: {'Content-Type': undefined}
        }).success(function (data) {
            if (data == "failed") {
                // if not successful, bind errors to error variables
                $scope.errorFinal = "Failed";
            } else {
                $scope.formData.image_name = data;
            }
        }).error('failed');
    };

试试这个

angular.element(this).scope().uploadFile(this);

<input type="file" name="student_image" onchange="angular.element(this).scope().uploadFile(this)" ng-model="formData.studentImage" id="student_image">

JS

$scope.uploadFile = function(data){
    console.log(data.files[0]);
};
