在开发项目的时候，需要在有用户消息的时候提醒用户，刚好自己的QQ好友上线，QQ自动弹出一个消息提示，觉得不错。所以用javascript利用popup作了一个类似的功能。

titleContent = titleContent + "</table>";
titlePopupBody.innerHTML = titleContent;
ShowMsgBox();
}
function MsgBox()
{
len += 4;
if (len > 110)
{
window.clearInterval(tID);
}
else
{//170固定了消息提示框的宽度
titlePopup.show(document.body.clientWidth - 170, document.body.clientHeight - len, 170, len, top.document.body);
}
}
var tID
function ShowMsgBox()
{
tID = window.setInterval("MsgBox()",15);
}
