js复制

JS实现各种复制到剪贴板

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
