我希望图像应该在一段时间内连续旋转，当鼠标移过该图像旋转应该停止并且当单击它应该缩放时，当鼠标离开它应该再次开始旋转它已经停止的地方。
我有一个 div 作为
<div id="simplegallery2" style="width: 1024px; height: 300px; display: block;"></div>
jquery代码为
var mygallery2 = new simpleGallery({
wrapperid: "simplegallery2",
dimensions: [1024, 300],
imagearray: [
["Banner/img/3.jpg", ""],
["Banner/img/4.jpg", "", "", ""],
["Banner/img/5.jpg", "", "", ""],
//["Banner/img/4.jpg", "", "", ""],
],
autoplay: [true, 2500, 100],
persist: false,
fadeduration: 2000,
oninit: function () {
},
onslide: function (curslide, i) {
}
})
和 jquery 滑块插件作为
