一、實現點擊按鈕，複製文本框中的的內容
<script type="text/javascript">
function copyUrl2()
{
var Url2=document.getElementById("biao1");
Url2.select(); // 選擇對象
document.execCommand("Copy"); // 執行瀏覽器複製命令
lert("已複製好，可貼粘。");
}
</script>
<textarea cols="20" rows="10" id="biao1">用戶定義的代碼區域</textarea>
<input type="button" onClick="copyUrl2()" value="點擊複製代碼" />
二、複製專題地址和 url 地址，傳給 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複製代碼</title>
</head>
<body>
<p>
<input type="button" name="anniu1" onClick='copyToClipBoard()' value="複製專題名稱和url地址，傳給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("複製成功，請粘貼到你的QQ/MSN上推薦給你的好友");
}
</script>
三、直接複製 url
<input type="button" name="anniu2" onClick='copyUrl()' value="複製URL地址">
<script language="javascript">
function copyUrl()
{
var clipBoardContent=this.location.href;
window.clipboardData.setData("Text",clipBoardContent);
alert("複製成功!");
}
</script>
四、點擊文本框時，複製文本框裏面的內容
<input οnclick="oCopy(this)" value="你好.要copy的內容!">
<script language="javascript">
function oCopy(obj){
obj.select();
js=obj.createTextRange();
js.execCommand("Copy")
alert("複製成功!");
}
</script>
五、複製文本框或者隱藏域中的內容
<script language="javascript">
function CopyUrl(target){
target.value=myimg.value;
target.select();
js=myimg.createTextRange();
js.execCommand("Copy");
alert("複製成功!");
}
function AddImg(target){
target.value="[IMG]"+myimg.value+"[/ img]";
target.select();
js=target.createTextRange();
js.execCommand("Copy");
alert("複製成功!");
}
</script>
六、複製 span 標記中的內容
<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("複製成功!");
}
</script>
七、瀏覽器兼容 copyToClipboard("拷貝內容")
function copyToClipboard(txt) {
if (window.clipboardData) {
window.clipboardData.clearData();
clipboardData.setData("Text", txt);
alert("複製成功！");
} else if (navigator.userAgent.indexOf("Opera") != -1) {
window.location = txt;
} else if (window.netscape) {
try {
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
} catch (e) {
alert("被瀏覽器拒絕！\n請在瀏覽器地址欄輸入'about:config'並回車\n然後將 'signed.applets.codebase_principal_support'設置爲'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("複製成功！");
}
}
八、兼容各大瀏覽器的複製代碼（結合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("該地址已經複製，你可以使用Ctrl+V 粘貼。");
});
clip.glue('clip_button', 'clip_container' );
}
</script>
</head>
<body onLoad="init()">
<input id="fe_text" cols=50 rows=5 value=複製內容文本1 >
<span id="clip_container"><span id="clip_button"><b>複製</b></span></span>
</body>
</html
---------------------------------------------------------------------------------------------------------------------------------------
React
使用方法：package.json內
"dependencies": {
"copy-to-clipboard": "^3.0.5"
}
控制檯：
- npm install
- webpack
- webpack-dev-server
使用方法：
//引入
import copy from 'copy-to-clipboard';
//使用方法
copyUrl = () => {
copy(this.props.url);
message.success('複製成功，如果失敗，請在輸入框內手動複製.');
};
