  <p>Please see the image carefully. This page is auto refresh every 20 seconds. My issue is see the bottom of the image, i have 8 check box in backup frequency group. when ever i check or un check the check box , i cant able to save the changes due to page refresh. i know i can increase the time of refresh and its possible. But i need some other logic to prevent the checked or un checked value untill i click "Applay changes" (save). <br>
  For example the 8 checkbox have 8 different id, When ever i click the id , i set the value true when its checked, other wise false. etc . please write a code in jquery or javascript.</p>
  
  <p>Please come up with a working code for this doubt.  Thanks in  advance.</p>
