我已经创建了一个jquery转盘，并使用if条件来运行和停止转盘

我已经创建了一个jQuery旋转木马，如果条件是运行并停止它，如果复选框被选中，旋转木马向左运行，它正在发生，否则如果复选框未被选中，则旋转木马需要停止，我不知道该怎么做，请有人帮我做这个

$("#checkBox").click(function(){
    if($(this).prop("checked") == true){
        carouselRun();
    }
    else if($(this).prop("checked") == false){
        carouselStop();
    }
});  

jQuery(document).ready(function ($) {
    var mslideWidth = 500, mslideHeight = 105, speed = 3000,
	    slideCount = $('#slider ul li').length,
	    slideWidth = $('#slider ul li').width(),
	    slideHeight = $('#slider ul li').height(),
        sliderUlWidth = slideCount * slideWidth;
  
    function carouselRun(){
        setInterval(function () {
            moveRight();
		}, speed);
	};
    function carouselStop(){
		setInterval(function () {
			moveLeft();
		}, speed).stop();
	};
  
    $('#checkBox').click(function(){
		if($(this).prop("checked") == true){
			carouselRun();
		}
        else if ($(this).prop("checked") == false){
			carouselStop();
		}
	});	 
  
	if (mslideWidth != 0 || mslideHeight != 0){
		slideWidth = mslideWidth;
		slideHeight = mslideHeight;
		$('#slider ul li').css('width',mslideWidth);
		$('#slider ul li').css('height',mslideHeight);
	}
	$('#slider').css({ width: slideWidth, height: slideHeight });
	$('#slider ul').css({ width: sliderUlWidth, marginLeft: - slideWidth });
	$('#slider ul li:last-child').prependTo('#slider ul');
    function moveLeft() {
		$('#slider ul').animate({
			left: + slideWidth
		}, function () {
			$('#slider ul li:last-child').prependTo('#slider ul');
			$('#slider ul').css('left', '');
		});
	};
	function moveRight() {
		$('#slider ul').animate({
			left: - slideWidth
		},function () {
			$('#slider ul li:first-child').appendTo('#slider ul');
			$('#slider ul').css('left', '');
		});
	};
	$('a.control_prev').click(function () {
		moveLeft();
	});
	$('a.control_next').click(function () {
		moveRight();
	});
});
