1.实现点击按钮，复制文本框中的的内容

<script type="text/javascript">
function copyUrl2()
{
var Url2=document.getElementById("biao1");
Url2.select(); // 选择对象
document.execCommand("Copy"); // 执行浏览器复制命令
alert("已复制好，可贴粘。");
}
</script>
<textarea cols="20" rows="10" id="biao1">用户定义的代码区域</textarea>
<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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>Js复制代码</title>
</head>
<body>
<p>
<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">
<script language="javascript">
function copyToClipBoard(){
var clipBoardContent="";
clipBoardContent+=document.title;
clipBoardContent+="";
clipBoardContent+=this.location.href;
window.clipboardData.setData("Text",clipBoardContent);
alert("复制成功，请粘贴到你的QQ/MSN上推荐给你的好友");
}
</script>

3.直接复制 url

<input type="button" name="anniu2" onClick='copyUrl()' value="复制URL地址">
<script language="javascript">
function copyUrl()
{
var clipBoardContent=this.location.href;
window.clipboardData.setData("Text",clipBoardContent);
alert("复制成功!");
}
</script>

4.点击文本框时，复制文本框里面的内容

<input onclick="oCopy(this)" value="你好.要copy的内容!">
<script language="javascript">
function oCopy(obj){
obj.select();
js=obj.createTextRange();
js.execCommand("Copy")
alert("复制成功!");
}
</script>

5.复制文本框或者隐藏域中的内容

<script language="javascript">
function CopyUrl(target){
target.value=myimg.value;
target.select();  
js=myimg.createTextRange();  
js.execCommand("Copy");
alert("复制成功!");
}
function AddImg(target){
target.value="[IMG]"+myimg.value+"[/ img]";
target.select();
js=target.createTextRange();  
js.execCommand("Copy");
alert("复制成功!");
}
</script>

6.复制 span 标记中的内容

<script type="text/javascript">
</script>
<br />
<br />
<script type="text/javascript">function copyText(obj)  
{
var rng = document.body.createTextRange();
rng.moveToElementText(obj);
rng.scrollIntoView();
rng.select();
rng.execCommand("Copy");
rng.collapse(false);
alert("复制成功!");
}
</script>

7.浏览器兼容 copyToClipboard("拷贝内容")

function copyToClipboard(txt) {
            if (window.clipboardData) {
                window.clipboardData.clearData();
                clipboardData.setData("Text", txt);
                alert("复制成功！");

            } else if (navigator.userAgent.indexOf("Opera") != -1) {
                window.location = txt;
            } else if (window.netscape) {
                try {
                    netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
                } catch (e) {
                    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'");
                }
                var clip = Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);
                if (!clip)
                    return;
                var trans = Components.classes['@mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable);
                if (!trans)
                    return;
                trans.addDataFlavor("text/unicode");
                var str = new Object();
                var len = new Object();
                var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);
                var copytext = txt;
                str.data = copytext;
                trans.setTransferData("text/unicode", str, copytext.length * 2);
                var clipid = Components.interfaces.nsIClipboard;
                if (!clip)
                    return false;
                clip.setData(trans, null, clipid.kGlobalClipboard);
                alert("复制成功！");
            }
        }
