mass Framework flip插件

如果浏览器支持CSS3 transform 3D的话，我们可以玩许多东西，比如flip，即电子书软件的那种翻页效果。不过，像transform3D的高级东西，不是一般浏览器能玩转，更别提IE9了。因此这时轮到JS出马了。jQuery上素以插件多出名，在上面找了几个相关插件研究一翻，搞出了自己的flip插件。总共170行。

$.define("flip", "fx", function(){
    var flip = {
        begin: function() {
            var hyaline =  (!"1"[0] ? "#123456" : "transparent")//透明色，IE6不支持透明，因此要使用滤镜hack一下
            return {//初始化属性
                hyaline: hyaline,
                backgroundColor: hyaline,
                fontSize:0,
                lineHeight:0,
                borderTopWidth:0,
                borderLeftWidth:0,
                borderRightWidth:0,
                borderBottomWidth:0,
                borderTopColor: hyaline,
                borderBottomColor: hyaline,
                borderLeftColor: hyaline,
                borderRightColor: hyaline,
                background: "none",
                borderStyle: 'solid',
                height:0,
                width:0
            };
        },
        horizontal: function( obj ){
            var waist = obj.height /100 *25;
            var begin = flip.begin();
            begin.width= obj.width;//将初始属性克隆成三份，并逐渐改变它们
            return {
                hyaline: begin.hyaline,
                begin: begin,

                    left: obj.left - waist//向左移
                },
                end: {

IE下如果报错，请它刷新页面，再不行，下载回来看。

更详细的使用方法请到github，看它的文档。
