如何暂停然后恢复动画

Question

我有三次冲洗，应该从左向右移动。完成第一次冲洗动画后，应开始第二次冲洗动画，第二次冲洗动画完成后，应开始第三次冲洗动画。

这是我的代码： -

flush_1_interval = setTimeout(function(){        
                    $( "#move_flush1" ).animate({ 
                        right: "+=1120px"
                        },{
                            duration : 10000,
                            complete : function()
                            {

                                var is_flush1 = parseInt($('#flush1_present').val());

                                $('#flush_span').hide();

                                if(is_flush1 == 0)
                                {                           
                                    $('.strenght_progress_bar').animate({'width': '+=16.66%'},"slow");

                                    $('#bird1').animate({'width': '+=5%', 'margin-top': '-=5%'},"slow");
                                    $('.plus_animation').show();
                                    $('.plus_animation').html('<img src="images/plus-animation.gif" border="0" />');
                                    setTimeout(function() {
                                        $('.plus_animation').html('');
                                    }, 2000);

                                    $('#move_flush1').hide();


                                    $('#flush_span').hide();

                                    $('.splash-left').show();
                                    //$('#splash_span').show();
                                    if ($('.sound').hasClass("mute"))

工作正常，但现在我有两个按钮 - “暂停”和“开始”。单击“暂停”按钮时，应停止动画，单击“开始”时，应恢复动画。

我试过了： -

$('#pause').click(function()
{
    clearInterval(flush_1_interval);
    clearInterval(flush_2_interval);
    clearInterval(flush_3_interval);

});

停止动画，但我不知道如何在点击“开始”按钮时再次恢复动画。

我是这个动画的新手任何帮助将不胜感激。提前致谢
