通用处理程序问题 [英] generic handler question

问题描述

我有一个网页，该网页使用通用图像处理程序显示图像.加载图像需要花费几秒钟的时间，因此页面的其余部分在加载图像之前就已完成.我正在使用一个叠加层(使用div显示正在加载...)，一旦生成并显示了html，该代码就会被代码隐藏文件隐藏.
但是问题在于图像仍在加载并且覆盖层消失了.
无论如何，是否可以从处理程序中控制div或在隐藏代码的页面中找出图像已完成加载?

I have a webpage that displays an image using a generic imagehandler. the image takes a few seconds to load, so rest of the page is completed before the image is loaded. I am using an overlay (using a div showing loading...) that is hidden by the code-behind file once the html is generated and displayed.
But the problem is that the image is still loading and the overlay has gone.
Is there anyway to control the div from the handler or to figure out in code-behind page that the image has completed loading?
