一、实现点击按钮,复制文本框中的的内容
|
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!\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 |
