For restoring previous state of Html Element using Jquery

var divClone = $("#some_div").clone(); // Do this on $(document).ready(function() { ... })

$("#some_div").html("Yeah all good mate!"); // Change the content temporarily

// Use this command if you want to keep divClone as a copy of "#some_div"
$("#some_div").replaceWith(divClone.clone()); // Restore element with a copy of divClone

// Any changes to "#some_div" after this point will affect the value of divClone
$("#some_div").replaceWith(divClone);
