How to use this multidimensional array in javascript

Question

I am getting a multidimensional array in form of JSON from a php file as AJAX response , there are two values I am getting from it , name and email , I need to update name and email of two respective divs each 5 seconds.

PHP response in JSON form: {"sophia":"[email protected]"}

Below is my javascript code:

window.setInterval(function () {
            var xmlhttp = new XMLHttpRequest();
        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                var data = JSON.parse(xmlhttp.responseText);
                for (var index in links) {
              //update name div
               document.getElementById("name").innerHTML= links[index]; 
             //update email div
               document.getElementById("email").innerHTML= links[index];
                  }
                }
            }
            xmlhttp.open("GET", "get_data.php", true);
            xmlhttp.send(); 
        }, 5000);

My html code:

<div id="name"></div>
<div id="email"></div>

Should it not be document.getElementById("name").innerHTML= index;? — Sandeep Nayak

So, whats the problem? You said your background, your goal, your attempt... what's wrong? — alanmm

JSON === JavaScript Object Notation. What you have is a JS object, not an array. links.sophia will get you the email, if you don't know what the properties will be, for (var p in links) { if (links.hasOwnProperty(p)) links[p]; is how you should iterate over a JS object — Elias Van Ootegem

Since your Object looks like {"sophia":"[email protected]"}; Change it to:

....
document.getElementById("name").innerHTML= index;   //sophia
         //update email div
document.getElementById("email").innerHTML= links[index];  //obj['sophia']= [email protected]
....
