导读：代码如下:

function copyText() {

//复制内容

var txt = document.getElementById("table2").rows[1].cells[0].innerHTML;

//去除空格

txt = txt.replace(/ /," ");

//去除换行

txt = t

代码如下:

function copyText() {

//复制内容

var txt = document.getElementById("table2").rows[1].cells[0].innerHTML;

//去除空格

txt = txt.replace(/ /," ");

//去除换行

txt = txt.replace(/<BR><BR>/," ");

if (window.clipboardData) {

window.clipboardData.clearData();

window.clipboardData.setData("Text", txt);

alert("已经成功复制到剪帖板上！");

}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("已经成功复制到剪帖板上！");

}

}
