jquery click: how to check if the button is clicked or not clicked?

How can I not to run a code if a button is clicked? For instance, this timer in开发者_如何学Python my plugin will be triggered if the previous button is not clicked, but I don't want to run this timer code when the button is clicked.

$.fn.run_slide.timer_each = setTimeout(function() {
    $.fn.run_slide.loop_slide(object);
},o.timerEach);

This timer code is inside this chunk of code,

next.css({opacity: 0.0}).addClass('active').animate({opacity: 1.0}, o.timerTransition, function(){

    current.animate({opacity: 0.0}, o.timerTransition).removeClass('active last-active');

    $.fn.run_slide.timer_each = setTimeout(function() {
        $.fn.run_slide.loop_slide(object);
    },o.timerEach);


});

I was thinking to do something like this but I think it is not the right method,

if(!button_previous.click)
{
$.fn.run_slide.timer_each = setTimeout(function() {
        $.fn.run_slide.loop_slide(object);
    },o.timerEach);
}

Any ideas?

Thanks.

Edit:

found the problem in my code and this is my solution:

// Check if the next button or previous button is not clicked then fade the current slide.
 if(!button_previous.click) current.animate({opacity: 0.0}, o.timerTransition).removeClass('active last-active');

You can stop a timeout from being executed the next time by using clearTimeout(), passing the setTimeout() handler as a parameter.

Should be something like this

clearTimeout( $.fn.run_slide.timer_each );

But I'm not sure if you sticked the setTimeout handler in a good position.

Use clearTimeout, as demonstrated in this fiddle.
