How to read the text file or XML file using pure JavaScript and using no other library or framework

Question

I am trying to read the text file or an XML file but I am stuck.

How to pass the file name that I have to read. Once I get the contents of the file I am sure I will need to use regex but I am stuck on getting the file name and data inside it.

I am sure how to do this in jQuery, but I need to try this out using pure JavaScript and nothing else. Any pointers or suggestions would be of great help.

Answer 1

It is not possible to reliably read a filename using JavaScript only, due to security reasons. Even JQuery will fail at some point (Google Chrome tends to block Ajax calls to the local machine).

EDIT: An example of a JSON config object:

var config =
{
    color: "blue",
    time: "15:00",
    amount: 1,
    names: ["Bob", "John"]
}

var someName = config.names[1] //John
