    event.preventDefault();
    var $i = $( '#identity_id' ),
    input = $i[0].files[0];
    $.ajax({
       url:"{{ route('user.order.create') }}",
       method:"POST",
       data:{
            identity_id:input
       },
       dataType: 'json',
       contentType: false,

        event.preventDefault();
        var i = $( '#identity_id' ),
        var formData = new FormData();
        var input = i[0].files[0];
        formData.append('identity_id',input);
        $.ajax({
           url:"{{ route('user.order.create') }}",
           method:"POST",
           data:formData,
           contentType: false,
           cache: false,
           success:function(){
    
           }
         })
        })
       });
