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">用户定义的代码区域</textarea> <input type="button" 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" 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" 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 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！"); } }
js实现但击自动选中文本

当前最常用的最简洁还是这个，代码少，减少页面加载速度
