  How can I set default file name of input file

  Jul 19, 2019 06:56 AM|fatihbarut|LINK

  hi all,

  when user clicks the input file button I want to write 65847-68548654.pdf into its value to make it easy to chose right file among lots of others

  as far as I know, it wasn't allowed before 2017 because of security reasons but now it is possible.

  Could you tell me how can I do it?

  thanks

  No, it's still not possible for the same reasons.

  You can achieve it by using custom attributes of input file button. It is not meant to store data but to allow the developer to assign some values to them to use it later in the code since HTML is stateless.

  I recommend you to read about them - https://www.w3schools.com/tags/att_global_data.asp

  yeah there are lots of way to store data localy but I don't want to use them because of  security reasons therefore I chose sessions at first

  The data- attribute will not help with the file input, as the file name is can not be set by JavaScript.

  <script type="text/javascript">

      $(document).ready(function(){

          $('input[type="file"]').change(function(e){

              var fileName = e.target.files[0].name;

              alert('The file "' + fileName +  '" has been selected.');

          });

      });

  </script>

  The answer that you marked as correct does not set the default file name of the input. All it does is tell you the name of the file that the user selected. 

  As I said right at the beginning, it is not possible to set a value for the file name in an input type-file.
