Hello,

I need to read the data from the url “http://www.celestrak.com/NORAD/elements/stations.txt”

Have tried to fellow the sample on “Making HTTP Requests in JavaScript”

A part of the file “stations.txt” looks like:

Are you just trying to load the contents? Can you post the code you are currently using?

On this moment I have no code written in Javascript.
Have done this in Java as a test. ( and other languages)
For my furder program in principle i need only the first tree lines of the file, and store them in l1,l2 and l3 (variable)

Then i can proceed. Later I will it uses in NSBasic (Javascript)

Cheers, Jan

This is my code so far.

ReadFromStations.txt document.writeln("Read TLE data ISS"); var xhr = new XMLHttpRequest(); xhr.open('GET',"http://www.celestrak.com/NORAD/elements/stations.txt",false); xhr.send(); 
    xhr.onreadystatechange = ProcessRequest;
    
    function processRequest(e){
        document.writeln("responce");
        document.writeln(xhr.readyState);
    }
