script error

I wrote a code https://code.sololearn.com/WHdHzHUvyF1C/#js It works, but always adds a script error. Why? What should I do? Thanks! LuMA

All you have to do is check for readyState and status properties. For instance: Http.onreadystatechange = () -> { If (Http.readyState === 4 && Http.status === 200) { // Your code goes here. } else { // Error handling code goes here. } } For a more in-depth guide please checkout this link: https://www.w3schools.com/js/js_ajax_http_response.asp

Thank you, Xianort! Now, I got back 2 and 3 Http.readyState. Http.status is 200.
