一、實現點擊按鈕，復制文本框中的的內容
<script type="text/javascript">function copyUrl2(){var Url2=document.getElementById("biao1");Url2.select(); // 選擇對象document.execCommand("Copy"); // 執行瀏覽器復制命令alert("已復制好，可貼粘。");}</script><textarea cols="20" rows="10" id="biao1">用戶定義的代碼區域</textarea><input type="button" onClick="copyUrl2()" value="點擊復制代碼" />二、復制專題地址和 url 地址，傳給 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復制代碼</title></head><body><p><input type="button" name="anniu1" onClick='copyToClipBoard()' value="復制專題地址和url地址，傳給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("復制成功，請粘貼到你的QQ/MSN上推薦給你的好友");}</script>三、直接復制 url
<input type="button" name="anniu2" onClick='copyUrl()' value="復制URL地址"><script language="javascript">function copyUrl(){var clipBoardContent=this.location.href;window.clipboardData.setData("Text",clipBoardContent);alert("復制成功!");}</script>四、點擊文本框時，復制文本框里面的內容
<input onclick="oCopy(this)" value="你好.要copy的內容!"><script language="javascript">function oCopy(obj){obj.select();js=obj.createTextRange();js.execCommand("Copy")alert("復制成功!");}</script>五、復制文本框或者隱藏域中的內容
<script language="javascript">function CopyUrl(target){target.value=myimg.value;target.select(); js=myimg.createTextRange(); js.execCommand("Copy");alert("復制成功!");}function AddImg(target){target.value="[IMG]"+myimg.value+"[/ img]";target.select();js=target.createTextRange(); js.execCommand("Copy");alert("復制成功!");}</script>六、復制 span 標記中的內容
<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("復制成功!");}</script>七、瀏覽器兼容 copyToClipboard("拷貝內容")
function copyToClipboard(txt) { if (window.clipboardData) { window.clipboardData.clearData(); clipboardData.setData("Text", txt); alert("復制成功！"); } else if (navigator.userAgent.indexOf("Opera") != -1) { window.location = txt; } else if (window.netscape) { try { netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect"); } catch (e) { alert("被瀏覽器拒絕！/n請在瀏覽器地址欄輸入'about:config'并回車/n然后將 'signed.applets.codebase_principal_support'設置為'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("復制成功！"); } }八、兼容各大瀏覽器的復制代碼（結合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("該地址已經復制，你可以使用Ctrl+V 粘貼。"); }); clip.glue('clip_button', 'clip_container' ); }</script></head><body onLoad="init()"><input id="fe_text" cols=50 rows=5 value=復制內容文本1 ><span id="clip_container"><span id="clip_button"><b>復制</b></span></span></body></html>新聞熱點
