The example in this article describes the js method of copying text or pictures to the clipboard after clicking. The code is very concise and practical. The specific function code is as follows:

Implement copy text code: 

<table width="99%" border="0" cellpadding="0" cellspacing="0" class="firtable"> 
  <tr> 
  <th width="100%" style="color: white;"><s:text name="询单明细"></s:text></th> 
  </tr> 
 <tr> 
  <td align="center">  
   <textarea name="inquiryContact1" id="inquiryContact1" rows="15" cols="60" readonly="readonly"></textarea> 
    <div id="inquiryInfoDIV" style="display:none"> 
      <s:property value="inquiryContact" escape="false"/> 
    </div> 
    <script>     dojo.byId("inquiryContact1").innerText=dojo.byId("inquiryInfoDIV").innerText; 
   </script> 
  </td> </tr> 
 <tr> 
  <td align="center"> 
   <input type="button" id="button" name="button" value="复制" onclick="copyContact()"/> 
  </td> </tr> </table> 
 

<script type="text/javascript"> 
  var i = 0 ;  
  function copyContact(){ 
    var contat = document.getElementById("inquiryContact1").value; 
    window.clipboardData.setData('text', contat); 
    if(window.clipboardData.getData('text')==''){ 
      if(i==1){ 
        alert("复制失败，请手动Ctrl+C快捷键复制！"); 
      }else{ 
        alert("复制失败，请重新复制！"); 
        i = 1; 
      } 
    }else{ 
       alert("内容已经复制到剪贴板！"); 
    } 
  } 
</script>

Implement the code for copying images: 

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 
<title>Insert title here</title> 
<SCRIPT LANGUAGE="JScript"> 
var oPopup = window.createPopup(); 
function ButtonClick(div) 
{ 
//var div = document.getElementById('divId'); 
div.contentEditable = 'true'; 
var controlRange; 
if (document.body.createControlRange) { 
controlRange = document.body.createControlRange(); 
controlRange.addElement(div); 
controlRange.execCommand('Copy'); 
} 
div.contentEditable = 'false'; 
} 
</SCRIPT> 
</head> 
<body> 
  <div id="divId1"> 
    <img src="F:/2012070518474964.jpg" onclick="ButtonClick(this)"> 
  </div> 
</BODY> 
</body> 
</html>
