这篇文章主要介绍了JS将制定内容复制到剪切板的方法,需要的朋友可以参考下
复制代码 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!");
}
}
