再会，

我的 jquery 轮播有问题，我做到了一切正常，但只有当我点击箭头时，但我不知道如何进行自动滚动。这是我的代码。你能帮助我吗？感谢您的回复。

$(document).ready(function() {
        //move he last list item before the first item. The purpose of this is if the user clicks to slide left he will be able to see the last item.
        $('#carousel_ulP li:first').before($('#carousel_ulP li:last')); 


        //when user clicks the image for sliding right        
        $('#right_scrollP img').click(function(){

            //get the width of the items ( i like making the jquery part dynamic, so if you change the width in the css you won't have o change it here too ) '
            var item_width = $('#carousel_ulP li').outerWidth() + 10;

            //calculae the new left indent of the unordered list
            var left_indent = parseInt($('#carousel_ulP').css('left')) - item_width;

            //make the sliding effect using jquery's anumate function '
            $('#carousel_ulP:not(:animated)').animate({'left' : left_indent},500,function(){    
                auto: 2,
                //get the first list item and put it after the last list item (that's how the infinite effects is made) '
                $('#carousel_ulP li:last').after($('#carousel_ulP li:first')); 

                //and get the left indent to the default -210px
                $('#carousel_ulP').css({'left' : '-210px'});
            }); 
        });

        //when user clicks the image for sliding left
        $('#left_scrollP img').click(function(){

            var item_width = $('#carousel_ulP li').outerWidth() + 10;

            /* same as for sliding right except that it's current left indent + the item width (for the sliding right it's - item_width) */
            var left_indent = parseInt($('#carousel_ulP').css('left')) + item_width;

            $('#carousel_ulP:not(:animated)').animate({'left' : left_indent},500,function(){    

            /* when sliding to left we are moving the last item before the first list item */            
            $('#carousel_ulP li:first').before($('#carousel_ulP li:last')); 

            /* and again, when we make that change we are setting the left indent of our unordered list to the default -210px */
            $('#carousel_ulP').css({'left' : '-210px'});
            });


        });
  });
