Retrieve data from PHP file by ajax - php

Question

I found a script on the net, which makes two PHP files interact.
Specifically, the first file (details.php) shows some statistical data of a football match. If the match is in progress, I show the live score by running another PHP file (live_score.php). The two files interact thanks to the following script, present in the details.php file
$(document).ready(function(){
setInterval(function() {
var id=<?php echo"$id"?>;
var x = "<?php echo"$cod"?>";
$("#risultato").load("live_score.php", {var:id, x});
refresh();
}, 5000);
});
from details.php, I call live_score.php passing it some parameters.
These parameters are used by the live_score.php file to retrieve the score and other information in real time.
To print the result on the screen in details.php, I use a simple ECHO inside the live_score.php file, but I would like to retrieve this data and the others in a different way, via ajax if possible, but I don't know if it can be done and how....can you help me please? Thank you

I think you have already solved half of your problem. From your code , you should first remove the "refresh()" to stop reloading the page every 5 seconds.
then make sure that the the payload is correct, because the word "var" is a reserved keyword in JavaScript.
HTML
<div id="risultato"></div>
Javascript
$.ajax({
url: "live_score.php",
type: "POST",
data: { id, x},
success: function(response) {
//this response will be the data from "live_score.php"
//now assuming that
// 1. you use vanilla javascript with plain html + css
// 2. the returning reponse looks like this
// [{"teamName": "theTeam1", "score": 10}, {"teamName": "theTeam2", "score": 10}]
//Clear the current score
$("#risultato").empty();
// Now iterate through the response,
$.each(response, function(index, item) {
var teamName = item.teamName;
var score = item.score;
var html = "<p><strong>" + teamName + "</strong>: " + score + "</p>";
// this code will append (add to the end) the data iterated
$("#risultato").append(html);
});
},
error: function(xhr, status, error) {
//if your code or ajax call had any problems ,
//you can debug here and write error handling logic here, like
if(error){
alert("failed to fetch data");
console.log(error);
}
}
});
