本文实例讲述了js实现点击后将文字或图片复制到剪贴板的方法，代码非常简洁实用，具体功能代码如下所示：

实现复制文字代码：

<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>

实现复制图片代码：

<!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="/UploadFiles/2021-04-02/2012070518474964.jpg">
