jQuery插件之图片滑动1

拜读了两位高手的大作，我也揣摩着实践一下，也为以后减少一点工作量

jQuery实例：图片展示效果

JavaScript 图片滑动展示效果

插件代码( 本人技术、天赋、时间有限JavaScript 图片滑动展示效果搞不来，此代码等于是封装了jQuery实例：图片展示效果)

                });
                ///原理就是 鼠标移上去,  该图片和它前面的图片的left都为minWidth*(图片在图片数组中的索引), 后面的都为minWidth*(图片在图片数组中的索引)+图片的宽度.
                ///动画就是一些图片向前走，一些图片向后走，结果把鼠标所在的图片给“暴露”出来了。
            });
        }

调用

window.onload = function() {
            var srcs = new Array;
            var texts = new Array;
            var hrefs = new Array;
            for (var i = 1; i <= 5; i++) {
                srcs.push("p" + i + ".jpg");
                texts.push("显示。。。显示。。。显示。。。显示。。。显示。。。显示。。。");
                hrefs.push("http://www.baidu.com");
            }
            $("#div_").ImgsTurn({

//                divW: 400,
//                divH: 300,
//                divPhotoW:200,             
                photosSrc:srcs,
                spanText: texts,
                spanHref:hrefs
            });
        }
