i can upload image but when i did not upload it need store null value how pass null value.
when i didnot call click upload means its need send null value how to do this.
function readURL(input) { if (input.files && input.files[0]) { var reader = new FileReader(); reader.onload = function (e) { $('#blah') .attr('src', e.target.result) .width(150) .height(200); }; reader.readAsDataURL(input.files[0]); } }
