我是靠谱客的博主忧伤羽毛，最近开发中收集的这篇文章主要介绍JS简单的轮播的图片滚动实例，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

[javascript]

复制代码代码如下:

var forimg = function (foritem, hoverStop, defaultfor) {  
        var _foritem = foritem.constructor == jQuery ? foritem : $(foritem);  
        var imgarr = [  
            { "z-index": 1, "width": 100, "height": 100, "left": 0, "top": "75px" },  
            { "z-index": 2, "width": 200, "height": 200, "left": 50, "top": "25px" },  
            { "z-index": 3, "width": 300, "height": 250, "left": 150, "top": "0" },  
            { "z-index": 2, "width": 200, "height": 200, "left": 370, "top": "25px" },  
            { "z-index": 1, "width": 100, "height": 100, "left": 520, "top": "75px" }  
        ];  
        _foritem.each(function (i) {  
            var _this = $(this);  
            _this.css(imgarr[i] || imgarr[4]);  
            _this.find("img").css(imgarr[i] || imgarr[4]);  
        });   www.uoften.com
        var _for = function (_i, data, nulldata, callback) {  
            $(foritem).each(function (i) {  
                var self = $(this);  
                setTimeout(function () {  
                    self.css("z-index", (data[i + _i] || nulldata)["z-index"])  
                    self.stop().animate(data[i + _i] || nulldata);  
                    self.find("img").stop().animate(data[i + _i] || nulldata, function () {  
                        callback.call(self, i);  
                    });  
                });

            } else {  
                that.rightfor();  
            }  
        }  
        var forimgInterval = setInterval(defaultforfun, 1000);  
        if (hoverStop) {  
            _foritem.hover(function () {  
                clearInterval(forimgInterval);  
            }, function () {  
                forimgInterval = setInterval(defaultforfun, 1000);  
            });  
        }  
        this.leftfor = function () {  
            var nuldata = { "z-index": -1, "width": 100, "height": 100, "left": 520, "top": "75px" };  
            imgarr[0]["z-index"] = 1;

            _for(1, imgarr, nuldata, function (i) {  
                if (i == _foritem.length - 1) {
