  <script type="text/javascript">

------解决方案--------------------
创建实例然后通过实例调用
JScript code
var o=new createPicMove(/*a,b,c参数的值*/)
o.Next();
o.Previouse()

------解决方案--------------------

你这个是类似于工厂函数
createPicMove().Previous()就可以调用
HTML code
function aa(){
                var o = function(){
                    this.name = "深蓝&quo
