• Js浮动广告效果实现


    第一种 漂浮广告 不符合W3C
    JavaScript漂浮广告代码,很不错,代码精简,不过一次只有漂一个,复制就能用了。希望站长朋友喜欢。

    var R= document.body.clientWidth-obj.offsetWidth 
    var B = document.body.clientHeight-obj.offsetHeight 
    obj.style.left = x + document.body.scrollLeft 
    obj.style.top = y + document.body.scrollTop 
    x = x + step*(xin?1:-1) 
    if (x < L) { xin = true; x = L} 
    if (x > R){ xin = false; x = R} 
    y = y + step*(yin?1:-1) 
    if (y < T) { yin = true; y = T } 
    if (y > B) { yin = false; y = B }

      第五种 亲自实践过,可以实现从左上角自动移动到右下角

    说明:jquery在1.9开始不支持.live()方法的写法而改用.on(),见http://jquery.com/upgrade-guide/1.9/#live-removed.该插件中关闭图片链接使用了.live().请根据自己情况自行修改.

                openStyle: 1, //跳转页打开方式 1为新页面打开  0为当前页打开

            };
