js实现各种复制到剪贴板的方法(分享)

一、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" />

 二、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>

三、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>

四、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>

五、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>

六、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>

七、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！");
   }
  }

八、兼容各大浏览器的复制代码（结合ZeroClipboard.js）

<html>
<head>
<title>Zero Clipboard Test</title>
<script type="text/javascript" src="ZeroClipboard.js"></script>
<script language="JavaScript">
 var clip = null;
 function $(id) { return document.getElementById(id); }
 function init() {
   clip = new ZeroClipboard.Client();
   clip.setHandCursor(true);
   clip.addEventListener('mouseOver', function (client) {
 // update the text on mouse over
 clip.setText( $('fe_text').value );
   });

   clip.addEventListener('complete', function (client, text) {
 //debugstr("Copied text to clipboard: " + text );
 alert("该地址已经复制，你可以使用Ctrl+V 粘贴。");
   });
   clip.glue('clip_button', 'clip_container' );
 }
</script>
</head>
<body onLoad="init()">
<input id="fe_text" cols=50 rows=5 value=复制内容文本1 >
<span id="clip_container"><span id="clip_button"><b>复制</b></span></span>
</body>
</html
