Dear Experts,

I am doing an ASP.Net project, I need to send some datas and post form data through javascript to webservice....

Here is the below code of javascript.

function startUploading() {

        // get form data for POSTing
        //var vFD = document.getElementById('form-student-profile').getFormData(); // for FF3
        var vFD = new FormData(document.getElementById('form-student-profile'));

        // create XMLHttpRequest object, adding few event listeners, and POSTing our data
        var oXHR = new XMLHttpRequest();
        oXHR.upload.addEventListener('progress', uploadProgress, false);
        oXHR.addEventListener('load', uploadFinish, false);
        oXHR.addEventListener('error', uploadError, false);
        oXHR.addEventListener('abort', uploadAbort, false);'POST','../../Webservice.asmx/Img_Upload');

       // set inner timer
        oTimer = setInterval(doInnerUpdates, 300);

Here is the code in WebService

[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public void Img_Upload()
    HttpContext postedContext = HttpContext.Current;
    HttpPostedFile file = postedContext.Request.Files[0];

    string name = file.FileName;
    byte[] binaryWriteArray = new
    file.InputStream.Read(binaryWriteArray, 0,

    FileInfo file_Info = new FileInfo(file.FileName);
    string ext = file_Info.Extension;

    string file_Name = Guid.NewGuid().ToString() + "_" + DateTime.Now.Day + DateTime.Now.Month + DateTime.Now.Year + ext;

    FileStream objfilestream = new FileStream(Server.MapPath("img//profilePIC//" + file_Name), FileMode.Create, FileAccess.ReadWrite);
    objfilestream.Write(binaryWriteArray, 0,

    SetVal.Profile_PIC = file_Name;


Here i can get the image file sucessfully, and i need to get some more string datas from that javascript function to this Webservice function....

Is there any method to get the file and datas ..??

please Help me..

Thanks and regards,

I found your question looking for some help myself with something very similar.
You can easily add some more values to your POST.

In you javascript you can simply add:
vFD.append("key1", "somevalue");

and in the codebehind:
string value = postedContext.Request["key1"];
