1.实现点击按钮，复制文本框中的的内容
1 <script type="text/javascript"> 2 function copyUrl2() 3 { 4 var Url2=document.getElementById("biao1"); 5 Url2.select(); // 选择对象 6 document.execCommand("Copy"); // 执行浏览器复制命令 7 alert("已复制好，可贴粘。"); 8 } 9 </script> 10 <textarea cols="20" rows="10" id="biao1">用户定义的代码区域</textarea> 11 <input type="button" onClick="copyUrl2()" value="点击复制代码" />
2.复制专题地址和 url 地址，传给 QQ/MSN 上的好友
1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 2 <html xmlns="http://www.w3.org/1999/xhtml"> 3 <head> 4 <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> 5 <title>Js复制代码</title> 6 </head> 7 <body> 8 <p> 9 <input type="button" name="anniu1" onClick='copyToClipBoard()' value="复制专题地址和url地址，传给QQ/MSN上的好友"> 10 <script language="javascript"> 11 function copyToClipBoard(){ 12 var clipBoardContent=""; 13 clipBoardContent+=document.title; 14 clipBoardContent+=""; 15 clipBoardContent+=this.location.href; 16 window.clipboardData.setData("Text",clipBoardContent); 17 alert("复制成功，请粘贴到你的QQ/MSN上推荐给你的好友"); 18 } 19 </script>
3.直接复制 url
1 <input type="button" name="anniu2" onClick='copyUrl()' value="复制URL地址"> 2 <script language="javascript"> 3 function copyUrl() 4 { 5 var clipBoardContent=this.location.href; 6 window.clipboardData.setData("Text",clipBoardContent); 7 alert("复制成功!"); 8 } 9 </script>
4.点击文本框时，复制文本框里面的内容
1 <input onclick="oCopy(this)" value="你好.要copy的内容!"> 2 <script language="javascript"> 3 function oCopy(obj){ 4 obj.select(); 5 js=obj.createTextRange(); 6 js.execCommand("Copy") 7 alert("复制成功!"); 8 } 9 </script>
5.复制文本框或者隐藏域中的内容
1 <script language="javascript"> 2 function CopyUrl(target){ 3 target.value=myimg.value; 4 target.select(); 5 js=myimg.createTextRange(); 6 js.execCommand("Copy"); 7 alert("复制成功!"); 8 } 9 function AddImg(target){ 10 target.value="[IMG]"+myimg.value+"[/ img]"; 11 target.select(); 12 js=target.createTextRange(); 13 js.execCommand("Copy"); 14 alert("复制成功!"); 15 } 16 </script>
6.复制 span 标记中的内容
1 <script type="text/javascript"> 2 </script> 3 <br /> 4 <br /> 5 <script type="text/javascript">function copyText(obj) 6 { 7 var rng = document.body.createTextRange(); 8 rng.moveToElementText(obj); 9 rng.scrollIntoView(); 10 rng.select(); 11 rng.execCommand("Copy"); 12 rng.collapse(false); 13 alert("复制成功!"); 14 } 15 </script>
7.浏览器兼容 copyToClipboard("拷贝内容")
1 function copyToClipboard(txt) { 2 if (window.clipboardData) { 3 window.clipboardData.clearData(); 4 clipboardData.setData("Text", txt); 5 alert("复制成功！"); 6 7 } else if (navigator.userAgent.indexOf("Opera") != -1) { 8 window.location = txt; 9 } else if (window.netscape) { 10 try { 11 netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect"); 12 } catch (e) { 13 alert("被浏览器拒绝！ 请在浏览器地址栏输入'about:config'并回车 然后将 'signed.applets.codebase_principal_support'设置为'true'"); 14 } 15 var clip = Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard); 16 if (!clip) 17 return; 18 var trans = Components.classes['@mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable); 19 if (!trans) 20 return; 21 trans.addDataFlavor("text/unicode"); 22 var str = new Object(); 23 var len = new Object(); 24 var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString); 25 var copytext = txt; 26 str.data = copytext; 27 trans.setTransferData("text/unicode", str, copytext.length * 2); 28 var clipid = Components.interfaces.nsIClipboard; 29 if (!clip) 30 return false; 31 clip.setData(trans, null, clipid.kGlobalClipboard); 32 alert("复制成功！"); 33 } 34 }
