100分求一个读剪贴板的小问题

[yaojian524]

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。

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

那我应该怎么做呢？

js里用window.clipboardData.getData("text");可以取文本，但我想取html啊

[yaojian524]

window.clipboardData.getData( "html");又报错

[cxx1997]

首先，肯定是用JS来获取

其次，取出来的文本，你是不是可以转换成HTML？

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.
