Javascript: Read text file from project folder to string

Question

How can we copy a content of text file from project file path to a string variable in javascript.

I used below code but it gives "Access Denied" error.

var sHTML = "";
var rawFile = new XMLHttpRequest();
rawFile.open("GET", "file://~/Templates/NewGridTemplate.txt", true);
      sHTML = rawFile.responseText;

Answer 1

Read the html template in C# code and then send it to your html code and assign to innerHTML

   using (StreamReader sr = new StreamReader(@"D:\Template.html")){
   // Read the stream to a string, and write the string to the console.
   obj.svar = sr.ReadToEnd().Replace(Environment.NewLine, " ");
   //Console.WriteLine(line);
   }
