JSON Contoh
Contoh ini membaca data JSON dari server web menjalankan PHP dan MySQL:
customers.html
<!DOCTYPE html>
<html>
<body>
<h1>Customers</h1>
<div id="id01"></div>
<script>
var xmlhttp = new XMLHttpRequest();
var url = "http://www.w3ii.com/website/customers_mysql.php";
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState
== 4 && xmlhttp.status == 200) {
myFunction(xmlhttp.responseText);
}
}
xmlhttp.open("GET", url, true);
xmlhttp.send();
function
myFunction(response) {
var arr = JSON.parse(response);
var i;
var out = "<table>";
for(i = 0; i < arr.length; i++) {
out += "<tr><td>" +
arr[i].Name
+
"</td><td>" +
arr[i].City +
"</td><td>" +
arr[i].Country +
"</td></tr>";
}
out += "</table>";
document.getElementById("id01").innerHTML = out;
}
</script>
</body>
</html>
Cobalah sendiri " PHP Kode pada Server
Ini adalah kode PHP berjalan di server:
<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type:
application/json; charset=UTF-8");
$conn =
new mysqli("myServer", "myUser", "myPassword", "Northwind");
$result = $conn->query("SELECT
CompanyName, City, Country FROM Customers");
$outp = "[";
while($rs = $result->fetch_array(MYSQLI_ASSOC)) {
if ($outp != "[") {$outp .= ",";}
$outp .= '{"Name":"' . $rs["CompanyName"] . '",';
$outp .= '"City":"' . $rs["City"] . '",';
$outp .= '"Country":"'. $rs["Country"] . '"}';
}
$outp .="]";
$conn->close();
echo($outp);
