1、实现点击按钮,复制文本框中的的内容$ C, ?0 a6 P# c8 t1 o/ |' k/ |
- <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" />
原理:点击按钮的时候触发copyUrl2函数,根据biao1 ID选中对象,然后在根据execCommand复制选中内容,所以此时选择的内容必须是可视的,也就是说不能是隐藏的文本域。

7 h9 w ?& ]+ p$ p& h3 o |- <!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>
3、直接复制 url
2 _8 ~" `" a- K. n' {-
- <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>
4、点击文本框时,复制文本框里面的内容
5 p7 v7 ]4 ]! O- U5 x- <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>
5、复制文本框或者隐藏域中的内容
% r; {& J% h7 o X |: e-
- <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
- I+ M7 X( O. r' K3 p7 p-
- <script type="text/javascript"></script>
- <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")
" G4 o. G! ^: i( w- 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!");
- }
- }
8、兼容各大浏览器的复制代码(结合ZeroClipboard.js)" z' j7 g. k- b3 Z
-
- <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>
