	##Get The index number of the current scroll item, 0 represents the first element, 1 represents the second element, and so on. In addition, it should be noted that if multiple scroll items are obtained, only the index number of the first scroll item will be returned.
jQuery	Return all scrolls Item, the result is returned as jquery object.

getPageAmount()	number	Get the current scroll bar number of pages.
getPageIndex()	number	Returns the current paging index Number.For example, if paging is set to 5 scroll items/page, and the current scroll item position is 7, then 1 (second page) will be returned
getRoot()	jQuery	Get the upper-level node of the scroll item.
getSize()	number	Returns the size of the scroll item quantity. This method is equivalent to getConf().size
##getVisibleItems()	jQuery	Get a list of currently visible scroll items, which is a jquery object. The number of visible scroll items is defined by the size attribute of the configuration object.

prev()## in the above method table #Method The following methods, in addition to the parameters carried in the table, also contain two implicit parameters: speed and callback. The speed parameter is used to control the duration of the animation effect of the scroll item, and callback is its callback method. For specific implementation, please refer to scrollable's prev() method usage example. Specific usage:

var scrollable=$("p.scrollable").scrollable();
//alert(scrollable.getConf().prev);//获取配置对象中的prev属性
scrollable.getConf().speed=200;//设置配置对象的speed属性
//alert(scrollable.getIndex());//获取当前滚动项的索引
//alert(scrollable.getItems().length);//获取当前滚动项的数量
//alert(scrollable.getItemWrap().html());//获取包含滚动项的节点(class=scrollable)，并将所有滚动项显示出来
//alert(scrollable.getPageAmount());//获取当前滚动栏分页数
//alert(scrollable.getPageIndex());//获取当前所在分页
//alert(scrollable.getRoot().html());//获取滚动项的上一级节点（id=thumbs）
//alert(scrollable.getSize());
//alert(scrollable.getVisibleItems().length);//获取当前可见滚动项数量
scrollable.next();//如果有下一个滚动项，则跳转到下一个滚动项
scrollable.prev(3000,function(){return true});//跳转到前一滚动项
//var seekTo= scrollable.click(0).seekTo(2,1000,function(){
    //alert(this.getIndex());
//});
//scrollable.move(2);
//scrollable.prevPage();//跳转到前一页
//scrollable.nextPage();//跳转到下一页
//scrollable.setPage(1);//跳转到下一页
//scrollable.begin();//跳转到第一个滚动项
//scrollable.end();//跳转到最后一个滚动项
scrollable.click(3);//使第四个滚动项处于选中状态
scrollable.onBeforeSeek(function(){
    alert("you click the "+this.getIndex()+"st scrollable item!");
});
$("#remove").click(function(){
    scrollable.getItems().filter(":last").remove();//删除最后一个滚动项
    scrollable.reload().prev();//自动更新相关配置信息，并跳转到被删除滚动项的前一项
});

In addition, if your form page needs to adapt to the screen and be resized so that the form page does not deviate, you can use

scrollable.seekTo(index)
to solve.
