Send file data to file input element using JQuery & AJAX

Question

I use a JQuery library for cropping images , after click on crop button, Cropped image (result) is send back to HTML page via AJAX as "file data", Something like this:

data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAIwAAA
CMCAYAAACuwEE+AAAgAElEQVR4nOy8d7hdVZ3/z/xmfH4z83y...

I want to sent this result to server as normal image file, but i don't know how to "attach" data to <input type="file" name="image" id="ajaxresult" hidden> .

I tried $("#ajaxresult").value(result); , but no luck. server says its null.

   var formData = new FormData($('#formid')[0]);
  formData.append('image', $('input[type=file]')[0].files[0]);
  $.ajax({
    url: path,
    data: formData,
    type: 'POST',
    contentType: false, // NEEDED, DON'T OMIT THIS (requires jQuery 1.6+)
    processData: false, // NEEDED, DON'T OMIT THIS
    success:function(){

    }
  });

@fredi you want assign the base64 encode data to #ajaxresult file filed you will use it this var image = new Image(); image.src = 'data:image/png;base64,iVBORw0K...'; document.body.appendChild(image);
