I have an input to load files and JavaScript code to get the file name, that I found here on Stack Overflow:

My input:

<%= file_field_tag 'file' %>

The JavaScript code:

var fullPath = document.getElementById('file').value;
if (fullPath) {
   var startIndex = (fullPath.indexOf('\\') >= 0 ? fullPath.lastIndexOf('\\') : fullPath.lastIndexOf('/'));
   var filename = fullPath.substring(startIndex);
   if (filename.indexOf('\\') === 0 || filename.indexOf('/') === 0) {
      filename = filename.substring(1);
   }
   alert(filename);
}

Instead of turn it into an alert(filename), is there a way to make it save the file name into a text file?

Where do you want the text file? In the server or the clients browser? – João Costa Mar 05 '20 at 17:55
It is going to be saved locally, there will be a link to a history page and there the user will be able to access his history – user315139192111315 Mar 05 '20 at 18:01
You could use the method proposed in this [answer](https://stackoverflow.com/questions/8178825/create-text-file-in-javascript). – João Costa Mar 05 '20 at 18:19

Please don't use "edit" tags when editing your text. Instead, incorporate the new information into your question as if it'd been there initially. We can tell what changed if we need to look at the revision logs. – the Tin Man Mar 05 '20 at 19:27
Ah thanks for the tip – user315139192111315 Mar 05 '20 at 19:35
