我的任务
分享100分求一个读剪贴板的小问题
System.Windows.Forms.IDataObject iData = System.Windows.Forms.Clipboard.GetDataObject();
if (iData.GetDataPresent(System.Windows.Forms.DataFormats.Html))
{
string strValue = (string)iData.GetData(System.Windows.Forms.DataFormats.Html);
}
这段代码我放到winform里没有问题，可以取出数据。但是放到web里“iData”取出来的就是“null”，为什么呢？
在web里应该怎么读剪贴板的值呢？不是text值，是要读html的编码。

getData Method
--------------------------------------------------------------------------------
Retrieves the data in the specified format from the clipboard through the dataTransfer or clipboardData objects.
Syntax
sRetrieveData = object.getData(sDataFormat)
Parameters
sDataFormat Required. String that specifies one of the following data format values:
Text Retrieves data formatted as text.
URL Retrieves data formatted as a URL.
Return Value
String. Returns the data in the format retrieved from clipboard through the dataTransfer or clipboardData object. Depending on the information contained in setData, this variable can retrieve a path to an image, text, or an anchor URL.
Remarks
The getData method enforces cross-frame security and allows data transfers within the same domain only. To the user this means that dragging a selection between different security protocols, such as HTTP and HTTPS, will fail. In addition, dragging a selection between two instances of the browser with different security levels, where the first instance is set to medium and the second is set to high, will fail. Finally, dragging a selection into the browser from another drag-enabled application, such as Microsoft Word, also will fail.
To use the getData method to retrieve data from the clipboard within the oncopy or oncut event, specify window.event.returnValue=false within the event handler script.

web的代码是在WEB服务器上执行的，所以，你读的是服务器上的剪贴板的值
