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"><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){js=obj.createTextRange();js.execCommand("Copy")}</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！
请在浏览器地址栏输入'about:config'并回车
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 |
