1.实现点击按钮，复制文本框中的的内容
1 <scrip 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！\n请在浏览器地址栏输入‘about:config‘并回车\n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 }
