在网上参考了段代码

我的页面是aspx的，并使用了image控件，从数据库中读路径，并展示图片

那么怎么来取代
var container = $$("idContainer"), src = "http://images.cnblogs.com/cnblogs_com/cloudgamer/143727/r_mm14.jpg",

这里呢

那个代码好像只认图片格式 var container = $$("idContainer"), src = "http://images.cnblogs.com/cnblogs_com/cloudgamer/143727/r_mm14.jpg" 怎么把 src = "http://images.cnblogs.com/cnblogs_com/cloudgamer/143727/r_mm14.jpg" 替换成我的路径呢？图片的文件名都是从数据库钟读的

function loadimage(imageurl){
 
var container = $$("idContainer"), src = imageurl,
    options = {
        onPreLoad: function(){ container.style.backgroundImage = "url('http://images.cnblogs.com/cnblogs_com/cloudgamer/169629/o_loading.gif')"; },
        onLoad: function(){ container.style.backgroundImage = ""; },
        onError: function(err){ container.style.backgroundImage = ""; alert(err); }
    },
    it = new ImageTrans( container, options );
it.load(src);
//垂直翻转
$$("idVertical").onclick = function(){ it.vertical(); }
//水平翻转
$$("idHorizontal").onclick = function(){ it.horizontal(); }
//左旋转
$$("idLeft").onclick = function(){ it.left(); }
//右旋转
$$("idRight").onclick = function(){ it.right(); }
//重置
$$("idReset").onclick = function(){ it.reset(); }
//换图
$$("idLoad").onclick = function(){ it.load( $$("idSrc").value ); }
//Canvas
$$("idCanvas").onclick = function(){
    if(this.value == "默认模式"){
        this.value = "使用Canvas"; delete options.mode;
    }else{
        this.value = "默认模式"; options.mode = "canvas";
    }
    it.dispose();
    it = new ImageTrans( container, options );
    it.load(src);
}
 
}

使用   loadimage("http://images.cnblogs.com/cnblogs_com/cloudgamer/143727/r_mm14.jpg");
