复制代码 代码如下:
function copy_clip() {
var url = $("#back_info").html(); //需要复制的内容
var txt = url.substring(url.indexOf(":") + 1, url.length);
if (window.clipboardData) {
window.clipboardData.clearData();
window.clipboardData.setData("Text", txt);
alert('恭喜，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("您的firefox安全限制限制您进行剪贴板操作，请在新窗口的地址栏里输入'about:config'然后找到'signed.applets.codebase_principal_support'设置为true'");
return false;
}
