推荐答案

您可能不会搜索为了正确的ID。使用asp，源上的ID与运行时的ID不同。如果你运行它并查看浏览器上的控制台，你会得到很多'null'错误吗？



尝试这样的事情：

You might not be searching for the correct ID. with asp, the ID on the source is different than that at run time. If you run this and look at the console on the browser, are you getting a lot of 'null' errors?

Try something like this:

document.getElementById("<%=divpreview.ClientID%>").style.left=left.toString()+'px';

这将告诉系统在运行时提供元素的客户端ID。

This will tell the system to provide the Client ID of the element at runtime.
