Hi i am using this code for my AJAX JSON request but for some if i try to make jsonObj a global variable and console.log() it always comes up as undefined in the debugger console
To clarify my question, how can I retrieve a global variable from an AJAX JSON request
function loadJSON() {
var data_file = "https://www.tutorialspoint.com/json/data.json";
var http_request = new XMLHttpRequest();
try {
// Opera 8.0+, Firefox, Chrome, Safari
http_request = new XMLHttpRequest();
} catch (e) {
// Internet Explorer Browsers
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
http_request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {
// Something went wrong
alert("Your browser broke!");
return false;
}
}
}
http_request.onreadystatechange = function() {
if (http_request.readyState == 4) {
// Javascript function JSON.parse to parse JSON data
var jsonObj = JSON.parse(http_request.responseText);
// jsonObj variable now contains the data structure and can
// be accessed as jsonObj.name and jsonObj.country.
document.getElementById("Name").innerHTML = jsonObj.name;
document.getElementById("Country").innerHTML = jsonObj.country;
}
}
http_request.open("GET", data_file, true);
http_request.send();

<table class="src">

<tr>

<div id="Name">Sachin</div>
</td>
<td>
<div id="Country">India</div>
</td>
</tr>
</table>
<div class="central">
<button type="button" onclick="loadJSON()">Update Details </button>
</div>
