Member table

Method Description
clearData Removes one or more data formats from the clipboard through a dataTransfer or clipboardData object.
getData obtains data in the specified format from the clipboard through dataTransfer or clipboardData objects.
setData assigns data to the dataTransfer or clipboardData object in the specified format.

Example
The following example uses the setData and getData methods of the clipboardData object to perform a cut-and-paste operation through the shortcut menu.

Copy code The code is as follows:

<SCRIPT> var bResult; //Select the text to be cut. Trailing spaces in the text selection during cut events cause the cut // cut selection shortcut menu item to remain disabled. function fnLoad() { var r = document.body.createTextRange(); r.findText(oSource.innerText); r.select(); } // Enable the cut shortcut menu item, which is disabled by default when it is on a DIV function fnBeforeCut() { event.returnValue = false; } // Assign data to the window.clipboardData object in text format. // Display the result of the setData method (Boolean) in the input box below. function fnCut(){ event.returnValue = false; bResult = window.clipboardData.setData("Text",oSource.innerText); oSource.innerText = ""; tText.innerText = bResult; } // Enable the paste shortcut menu item, which is disabled by default when it is on a DIV function fnBeforePaste() { event.returnValue = false ; } // Cancel returnValue in onpaste to enter text. This operation has the default // behavior. function fnPaste() { event.returnValue = false; oTarget.innerText = window.clipboardData.getData("Text"); } </SCRIPT>
