Lets say you have the following function.  What I am having problem is trying to figure out of adding this function to 20 buttons.  Instead of saying button1.click function you just do a loop and add the events to all 20 buttons.

Use the same class (for example myclass) for all the button :

<input class="myclass" type="button" id ="btn1Start" />
<input class="myclass" type="button" id ="btn2Start" />
<input class="myclass" type="button" id ="btn3Start" />

Open in new window


so use :

$(".myclass").click(function() {

You could give all the buttons the same classNames and then do like so;-


$(".myButons").click(function () {
      
        });

You can use the start with selector too : http://api.jquery.com/attribute-starts-with-selector/
and end with : http://api.jquery.com/attribute-ends-with-selector/

$("input[type='button'][id^='btn'][id=$'Start']").click(function() {

But the question is how would you assign the timer function so that the timer index is all different.  Reason for this you want to have the ability to clear interval timer

This line here

timer3 = setInterval("$.do_time('timer3')", 1000);

timer3 should be a index or something

inside you get the button number/id with something like :

$("input[type='button'][id^='btn'][id=$'Start']").click(function() {
     var idNumber = $(this).attr("id").replace(/\D/g,""); // you get 1, 2, 3..., n
     setInterval("$.do_time('timer" + idNumber + "')", 1000);
     // rest of the code
});

A possible solution would need two changes to your page.
First add a class name to the button with the name of the desired timer.
like this:
<input type="button" id="btn1Start" class="timer1" value="button1" />

The second change would be the $(document).ready function
like this:
$(document).ready(function () {

    $(':input[type=button]').each(function(){   

        $(this).click(function () {

                var timerId = $(this).attr('class'),

                    action = "$.do_time('"+timerId+"',['00:00:03','00:00:06','00:00:09','00:00:15'])"

                window[timerId] = setInterval(action, 1000);

                $(this).attr("disabled", true);

        });

    });

       totaltimer = setInterval("$.displayTotal('totaltimer')", 1000);

});

Hi,

I have modified your initial code and here is the final solution.
Changes are:
-Times array is stored with the butto in data attribute.
-Second argument for do_time is the element id rather then times array.
- class 'timerButton' has been added to all buttons.

I have tested the above code in IE7&8, Chrome, FF.

		var i = $(this).attr('id').replace(/[^0-9]/g,'');
		setInterval('$.do_time("timer'+i+'", "'+$(this).attr('id')+'")', 1000);
	});
        totaltimer = setInterval("$.displayTotal('totaltimer')", 1000);


});
//Timer JQuery function
(function ($) {
   totaltime = "00:00:00";
   		// MODIFICATION: changed expireTime to times.
        $.do_time = function(timerID, timesEl) {
                
		var times = $('#'+timesEl).attr('data').split(',');
		
                var time = ($("#" + timerID).html()).split(':');
                var hour = parseInt(time[0], 10);
