File upload using MVC 4 with Ajax

by

Here is my small working sample, which uploads multiple files and uploads in a folder called as ‘junk’

Client Side….

    <html>
    <head>
    <title>Upload Example</title>
    <script src="https://stackoverflow.com/questions/20420828/~/Scripts/jquery-2.1.0.intellisense.js"></script>
    <script src="~/Scripts/jquery-2.1.0.js"></script>
    <script src="~/Scripts/jquery-2.1.0.min.js"></script>
    <script>
    $(document).ready(function () {
        $("#Upload").click(function () {
            var formData = new FormData();
            var totalFiles = document.getElementById("FileUpload").files.length;
            for (var i = 0; i < totalFiles; i++)
            {
                var file = document.getElementById("FileUpload").files[i];

                formData.append("FileUpload", file);
            }
            $.ajax({
                type: "POST",
                url: '/Home/Upload',
                data: formData,
                dataType: 'json',
                contentType: false,
                processData: false,
                success: function (response) {
                    alert('succes!!');
                },
                error: function (error) {
                    alert("errror");
                }
            });
        });
    });

</script>
</head>
<body>
    <input type="file" id="FileUpload" multiple />
    <input type="button" id="Upload" value="Upload" />
</body>
</html>

Server Side….

public class HomeController : Controller
{
    [HttpPost]
    public void Upload( )
    {
        for( int i = 0 ; i < Request.Files.Count ; i++ )
        {
            var file = Request.Files[i];

            var fileName = Path.GetFileName( file.FileName );

            var path = Path.Combine( Server.MapPath( "~/Junk/" ) , fileName );
            file.SaveAs( path );    
        }

    }
}
