複製代碼代碼如下:
<script type="text/javascript">
function copyCode(id){
var testCode=document.getElementById(id).value;
if(copy2Clipboard(testCode)!=false){
alert("產生的程式碼已經複製到貼上板，你可以使用Ctrl+V 貼到需要的地方去了哦！ ");
}
}
copy2Clipboard=function(txt){
if(window.clipboardData){
window.clipboardData.clearData();
window.clipboardData.setData("Text",txt);
}
else if(navigator.userAgent.indexOf("Opera")!=-1){
window.location=txt;
}
else if(window.netscape){
try{
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
}
catch(e){
alert("您的firefox安全限制限制您進行剪貼簿操作，請開啟'about:config'將

return false;
