jQuery file upload including variables

Question

Is it possible to use a file upload using jQuery/javascript that would include usable variables? (user selects file)

For example. Could I upload a file (.txt, or .js etc) with the following contents and be able to use the variables?

var cars = ["Saab", "Volvo", "BMW"];

var name = "bob";

Answer 1

Yes you can. Please check below for more in depth.

Add .txt or any files in formdata

var formData = new FormData();

var txxtFile = $('#input_file').prop('files')[0];
formData.append('file',txxtFile);

Append variables in formData

var carsArray = ["Saab", "Volvo", "BMW"];
formData.append(cars,  JSON.stringify(carsArray ));

Once you append all values to formData you have to pass formData in ajax request.

Let me know if it not works.
