I use barryvdh to create pdf file. But I wanna make some interactive page to user which is for example "Please wait" while creating PDF and disable the pdf button, and then enable the button again when create PDf is finish.

so this is my controller :

    $pdf = PDF::loadView('panel.invoice.pdf', $data)->setWarnings(false)->setPaper('a4', 'portrait');



    $pdf->save(storage_path($code['code'].'.pdf'));



    return response()->file(storage_path($code['code'].'.pdf'));

and this is my ajax :

    $(document).off('click', '.pdf').on('click', '.pdf', function(e){

     disBtn(btn_saving);

     loadItem(selector);

     $.ajax({

      url: 'invoice/pdf',

      type: "POST",

      data:  new FormData( $('#list_form')[0]),

      contentType: false,

      dataType: "json",

      cache: false,

      processData:false,

      success : function ( response ) {

       finishload(selector);

       location.reload();

      },

      error   : function ( jqXhr, response, errorThrown ) {

      }

     });

    });

but the pdf view doesn't appear if I do this with ajax and stuck, but the response is 200.

and then, what should I do about the file in storage? how can I delete the pdf file after user download from pdf view?
delete without this :

    "return response()->download(storage_path($code['code'].'.pdf'))->deleteFileAfterSend(true);"
