在.net中集成Mootools做图片动态翻页
最近由于工程需要，要做一个动态的幻灯图片功能，也就是说，图片必须是受控的，可翻页，可动态更新，网上的一些实例都是静态的多张幻灯，这些不能满足我的要求，找了半天，发现Mootools有个Fx.Tween功能，比较适用于幻灯，于是，只能自己动手了。
当客户端带参数进入这个页面，例如：PictureView.aspx?Id=XXX时，这张图片可由PictureView.aspx这个页面直接响应输出，或者提交给Ajax进行输出，我这里是用前aspx来输出的，接下来的翻页，是用Ajax完成的，借助了Mootools的Ajax与Fx.Tween功能。具体代码如下：（由于版面关系，Ashx代码这里没有给出，大家可以自己进行添加）

接下来是JS部分的:
window.addEvent('domready', function(){
var picsrc;
var d2;
$('prepic').addEvent('click', function(){
if(i > 1)
{
i = i-1;
new Request({url: "AjaxProductionSrc.ashx?Id=" + $('prepid').value + "&gettype=p",
method:'get' ,
evalScripts:true,
onSuccess: function(responseText) {
var responseContent = responseText.split('|');
if(responseContent[0] != "error")
{
picsrc = responseContent[0];
$('ptitle').innerHTML = responseContent[1];
$('ppoll').innerHTML = responseContent[2];
$('ptime').innerHTML = responseContent[3];
$('pnickname').innerHTML = responseContent[4];
$('nextpid').value = $('thispid').value;
$('thispid').value = $('prepid').value;
$('prepid').value = responseContent[5];
if(!$('div' + i))
{
d2 = document.createElement("img");
d2.id="div" + i;
d2.style.width = "800px";

}
}).send();
}
return false; // alternative syntax to stop the event
});

PS：虽然实现了翻页，并有幻灯效果，但是由于本人并没有做代码的优化与精简，所以期待大家一起来指出不足之处~
