File uploading in a local drive with angularjs

问题:

I'm beginner in angularjs. I read a lot about file uploading and etc. But couldn't find any topics for this case that i will describe in further.

I want to choose a file with helping of a button(with search Name) in below code

then when we click on second button (with upload Name), my chose file upload in a local drive that i made in D:\Uploaded Files already

for example I want choose a file from desktop with search button, then when we click on upload, this file copy to D:\Uploaded Files

If it's possible please show me in fiddler. Thanks all.

Thanks all for shairing

You need to use a directive like below.

uploader.directive("readfile", [function () {
    return {
        scope: {
            readfile: "="
        },
        link: function (scope, element, attributes) {
            element.bind("change", function (changeEvent) {
                var reader = new FileReader();
                reader.onload = function (loadEvent) {
                    scope.$apply(function () {
                        scope.readfile = { "FileName":changeEvent.target.value.split('\\').pop() , "Content":loadEvent.target.result , "Size":loadEvent.total };
                    });
                }
                reader.readAsDataURL(changeEvent.target.files[0]);
            });
        }
    }
}]);

For uploading the files:

function MyCTRL($scope, $http, $modal)
{
    $scope.currentFile="";

    $scope.currentFileGroup="";

    $scope.currentFileDescription="";

    $scope.attachedFile=[];

    $scope.fileUpload=function () 

    {

    $scope.attachedFile.push ({

        "fileGUID": GUID() + "." + $scope.currentFile.FileName.split('.').pop(),
        "fileName": $scope.currentFile.FileName,
        "fileGroup": $scope.currentFileGroup,
        "fileDescription": $scope.currentFileDescription,
        "fileSize": $scope.currentFile.Size,
        "fileContent": $scope.currentFile.Content,
        "fileState": "wait"
    });

    $scope.currentFile = "";
    $scope.currentFileGroup = "";
    $scope.currentFileDescription = "";
    $scope.AddBtnShow=false;

    var saveFile = new dataStructure();
    var fileContent = "";
    for (var i=0; i < $scope.attachedFile.length; i++) {
        if($scope.attachedFile[i].fileState!="sent") {
        fileContent = $scope.attachedFile[i].fileContent;
        saveFile.EntityInfo[0].Name = $scope.attachedFile[i].fileGUID;
        saveFile.EntityInfo[0].Type = "CUSTOMFILE";

            saveFile.EntityData = [
                {"Content": fileContent}
            ];
            var inputjsondata = JSON.stringify(saveFile);
            $http({ method: 'POST', url: rootURL + '/data/savefilecontent', data: inputjsondata, dataType: 'text', processData: false, async: false, headers: { 'Content-Type': 'application/json; charset=utf-8' } }).success(function (data) {
            });
            $scope.attachedFile[i].fileState = "sent";

            $scope.formData.Attachments.push({
                "FilenameGUID": $scope.attachedFile[i].fileGUID,
                "Filename": $scope.attachedFile[i].fileName,
                "Group": $scope.attachedFile[i].fileGroup,
                "Description": $scope.attachedFile[i].fileDescription,
                "UploadDate": uploadGregorianDate()                    
            });
        }
    }
};

And now everything is fine.

Did you mean upload a local file from your client computer to a server? or local to local?

If it's the first case:

• File upload sample: https://github.com/danialfarid/angular-file-upload
• If you want to give a try dumping as well to an azure storage: http://lemoncode.net/2014/01/15/angularjs-web-api-azure-storage/ (this sample contains the whole app including a directive, you can remove the azure storage part and directly dump into a server folder).
