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>/,\" \");

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\'\");
