The issue of unreadable URLs on the server side caused by a Javascript Ajax problem

I have successfully implemented code to send information from a website to a server. The code I used is as follows:

<!DOCTYPE html>
<html>
<script>
var Network = {"name":"", "password":""}
var json;
var xhr = new XMLHttpRequest();
var Json = JSON.stringify(Network)

function Info(sp) {
let svar = prompt(sp, "Enter information here");
return svar
}

Network.name = Info("Enter internet name");
Network.password = Info("Enter internet password");

console.log(Network);

xhr.open("GET", "/network?Json="+Json+"}", true);
xhr.send();
</script>
</html>

Although this code is functional, I am encountering an issue that I am unsure whether is a bug or error. When trying to deserialize the Json object on my esp8266 using the ArduinoJson library, I receive an error message stating "IncompleteInput." Upon inspecting the AJAX request here, it is evident that there is a missing end bracket in the text, which I suspect is causing the error. Manually typing in the missing character resolves the issue. How can I correct this problem?

Answer №1

The solution to my issue was discovered within the HTML page shared in my post. User romkey advised me to parse the string outside of the function where I was opening the XML object, and this solution worked immediately. The following code successfully resolved the problem:

<!--Here, the type of document is defined-->
<!DOCTYPE html>
<html>
<script>
//variables are defined here
var Network = {"name":"", "password":""}
var xhr = new XMLHttpRequest();
var Json;
var url;

//function to create pop-up boxes
function Info(sp) {
  let response = prompt(sp, "enter information here");
  return response;
}

//copying data from pop-up boxes to JavaScript object
Network.name = Info("Enter internet name");
Network.password = Info("Enter internet password");

//logging the object in the console
console.log(Network);

//converting Network object to JSON (JavaScript Object Notation)
Json = JSON.stringify(Network);

url = "/network?Json="+Json;

//sending the network name and password to the ESP
 xhr.open("GET", url, true);
 xhr.send();
</script>
</html>
