一、實(shí)現(xiàn)點(diǎn)擊按鈕，復(fù)制文本框中的的內(nèi)容
<script type="text/javascript">function copyUrl2(){var Url2=document.getElementById("biao1");Url2.select(); // 選擇對(duì)象document.execCommand("Copy"); // 執(zhí)行瀏覽器復(fù)制命令alert("已復(fù)制好，可貼粘。");}</script><textarea cols="20" rows="10">用戶定義的代碼區(qū)域</textarea><input type="button" value="點(diǎn)擊復(fù)制代碼" />
二、復(fù)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(fù)制代碼</title></head><body><p><input type="button" value="復(fù)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(fù)制成功，請(qǐng)粘貼到你的QQ/MSN上推薦給你的好友");}</script>
三、直接復(fù)制 url
<input type="button" value="復(fù)制URL地址"><script language="javascript">function copyUrl(){var clipBoardContent=this.location.href;window.clipboardData.setData("Text",clipBoardContent);alert("復(fù)制成功!");}</script>
四、點(diǎn)擊文本框時(shí)，復(fù)制文本框里面的內(nèi)容
<input value="你好.要copy的內(nèi)容!"><script language="javascript">function oCopy(obj){obj.select();js=obj.createTextRange();js.execCommand("Copy")alert("復(fù)制成功!");}</script>
五、復(fù)制文本框或者隱藏域中的內(nèi)容
<script language="javascript">function CopyUrl(target){target.value=myimg.value;target.select(); js=myimg.createTextRange(); js.execCommand("Copy");alert("復(fù)制成功!");}function AddImg(target){target.value="[IMG]"+myimg.value+"[/ img]";target.select();js=target.createTextRange(); js.execCommand("Copy");alert("復(fù)制成功!");}</script>
六、復(fù)制 span 標(biāo)記中的內(nèi)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(fù)制成功!");}</script>
七、瀏覽器兼容 copyToClipboard("拷貝內(nèi)容")
function copyToClipboard(txt) {if (window.clipboardData) {window.clipboardData.clearData();clipboardData.setData("Text", txt);alert("復(fù)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(qǐng)?jiān)跒g覽器地址欄輸入'about:config'并回車/n然后將 'signed.applets.codebase_principal_support'設(shè)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(fù)制成功！");}}
八、兼容各大瀏覽器的復(fù)制代碼（結(jié)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(jīng)復(fù)制，你可以使用Ctrl+V 粘貼。");});clip.glue('clip_button', 'clip_container' ); }</script></head><body><input cols=50 rows=5 value=復(fù)制內(nèi)容文本1 ><span><span><b>復(fù)制</b></span></span></body></html>
