Summary of methods for copying to the clipboard using JavaScript
In our daily development work, we often use the paste and copy function. Many times, our projects will also allow you to copy to the clipboard. Below we will introduce to you JavaScript Summary of methods for copying to the clipboard!
1. Click the button to copy the content in the text box
<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" />2. Copy the topic address and url address and send them to QQ/MSN Friends

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！");

<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>
