var oMyForm = new FormData();oMyForm.append("username", "Groucho");oMyForm.append("accountnum", 123456); oMyForm.append("file", $(‘#file‘)[0].files[0]);$.ajax({ ???url: ‘/Manage/UploadImg‘, ???type: ‘POST‘, ???cache: false, ???data: oMyForm, ???processData: false, ???contentType: false, ???async: false,error: function (request) {
