Code to control the clipboard through JS under IE_javascript skills

JavaScript can use the window.clipboardData object to process clipboard content
Save to the clipboard method setData(param1, param2)
param1: Data type text or URL, etc.
param2: Data content
From clipboard The method of reading data from the board is getdata(param1)
The method of clearing data is clearData(param1)
The following is an example demonstration

<title>Test operating clipboard</title> <button onclick="copyToClipboard();"> </button>Copy<input type="text" size="20" id="source" value="测试数据"> <button onclick="alert(window.clipboardData.getData('text'));"> </button>Show<button onclick="window.clipboardData.clearData('text');"> </button>Clear
[Ctrl A Select all Note: If you need to introduce external Js, you need to refresh to execute

]

The following is another example implementation Select characters on the page and drag them to the text area
Note that the window.event.dataTransfer object can also handle clipboard content, but it can only be used in drag-and-drop operations

<title> </title>Test operation clipboard 2 <textarea id="myTarget" ondrop="transferDrop();" ondragover="window.event.returnValue = false;" ondragenter="transferDrag();">Select us and drag us to the textarea below
[Ctrl A select all Note:

If you need to introduce external Js, you need to refresh to execute <script> function copyToClipboard() { var d=document.all("source").value; window.clipboardData.setData('text', d); } </script>]<script> function transferDrop() { window.event.srcElement.innerText = window.event.dataTransfer.getData("text"); window.event.returnValue = false; } function transferDrag() { window.event.dataTransfer.dropEffect = 'move'; window.event.returnValue = false; } </script>
