    hi
    i am trying to rotate a field inside variable in javascript
    this is a part of a code:


    var a = { sr: 22, id: 31, jab:45124, domain: 'aaa.com' };


    i am trying to rotate the domain field :
    aaa.com with bbb.com and/or ccc.com
    i already tried rotating it in many ways including all the rotate methods for images banners etc but no luck so far.
    how can i do it?

    -also tried rotating the whole line "var a ....." but i couldn't do it too

    thanks

    Have a look at Math.random()...

    Perhaps something like this:

    <!DOCTYPE html>
<html>
<head>
<title></title>
<script type="text/javascript">
var a = {
  "sr": 22,
  "id": 31,
  "jab": 45124,
  "domain": [
    "aaa.com",
    "bbb.com",
    "ccc.com"
  ]
};

var which = 0,
    show,
    len;

function rotateDomain() {
  show.innerHTML = a["domain"][which];

  which = ++which % len;
  // which = Math.floor(Math.random()*len); // or randomized alternative

  setTimeout(rotateDomain, 3000);
}

window.onload = function() {
  show = document.getElementById("showit");
  len = a["domain"].length;
  rotateDomain();
}
</script>
</head>
<body>
<div>
  <a href="#" id="showit"></a>
</div>
</body>
</html>
    Code (markup):
