this countdown function.

  <button class="ui toggle button" onclick="      hideshow(document.getelementbyid('onaysms')); show(this);" id="onaytoggle"> 

this button when click should activate.

<span id="time"></span> 

it starts when page start how can start when button clicked?

insert timer call in "onclick" event this, fired when click on button.

if have several buttons on page, advise give 1 id adding in html : id='timertoggle' , replacing $("button.toggle") in code below $("#timertoggle")

 jquery(function ($) {            $("button.toggle").click(function(){                var fiveminutes = 60 * 3,                    display = $('#time');                display2 = $('#time2');                starttimer(fiveminutes, display);                starttimer(fiveminutes, display2);            });         });
