I have a timer with a that makes a circle while it's running. It has a stop button but I would rather have a pause button. Right now when you hit the start buttons it starts from 0. I want it to just pause. I can't seem to figure it out because I don't have that much Jquery experience. The code should work if you paste it in an html page. The length would come from php code but I have that working ok and I have var length=20. I just need the pause button. Thanks...

Actually it's not perfect, my timings are completely off
Here's the fixed script

<script>
var timerSeconds = 20
var timer;
var percent = 0
var percentIncrease = 360 / (timerSeconds * 20)
var totaltime = 0

    function drawTimer(percent) {
        $('div.timer').html('<div id="slice"' + (percent > 180 ? ' class="gt50"' : '') + '><div class="pie"></div>' + (percent > 180 ? '<div class="pie fill"></div>' : '') + '</div>');
        var deg = percent;
        $('#slice .pie').css({
            '-moz-transform': 'rotate(' + deg + 'deg)',
                '-webkit-transform': 'rotate(' + deg + 'deg)',
                '-o-transform': 'rotate(' + deg + 'deg)',
                'transform': 'rotate(' + deg + 'deg)'
        });
    }

    function stopWatch() {
        if (percent >= 360) {
            clearInterval(timer);
            drawTimer(360);

        } else {
            percent += percentIncrease

            drawTimer(percent);
        }
    }
$(document).ready(function () {
    $('input[type=button]#watch').click(function (e) {
        e.preventDefault();
        clearInterval(timer)
        if ($('input[type=button]#watch').val() == 'Start') {
            $('input[type=button]#watch').val('Pause');
            timer = setInterval('stopWatch()', 50);
        } else {
            $('input[type=button]#watch').val('Start');
            clearInterval(timer);
        }
    });


    $('input[type=button]#watch').click();


});

Gary,

You wrote or fixed this code for me. Now I'm trying to send a page to Ajax when it is done but it seems to hang up if the cache is cleared in chrome. Can you find another solution to how I can send it to Ajax?

http://squareonemeditation.com/webapp/meditatetest.php

function drawTimer(percent){
		
		$('div.timer').html('<div id="slice"'+(percent > 50?' class="gt50"':'')+'><div class="pie"></div>'+(percent > 50?'<div class="pie fill"></div>':'')+'</div>');
		var deg = 360/100*percent;
		$('#slice .pie').css({
			'-moz-transform':'rotate('+deg+'deg)',
			'-webkit-transform':'rotate('+deg+'deg)',
			'-o-transform':'rotate('+deg+'deg)',
			'transform':'rotate('+deg+'deg)'
		});
		$('.percent').html(Math.round(percent)+'%');
	}
	
	$(stopWatch = function() { 
	
		if(percent >=100){
			drawTimer(100);
			clearInterval(timer);
							
					$.ajax({
						url: "postmeditate.php",
						type : "POST",
						data: { length: length, userid: userid},
					})
					.success(function (response){
						location.href = "tracking.php";
						location.href = "tracking.php";
						location.href = "tracking.php";     							
					})
					.error(function (e){
					});
			
		}else{
			percent += (timerSeconds/minutes)
			drawTimer(percent);
			counter++;
		}

});
