用链接的方式打开一个页面，该页面负责加载数据，怎么实现等待加载数据的过程显示“数据加载中”用asp.net 的ajax 中的updatepanel+progress控件是可以实现的，但是只能在本页通过按钮的触发方式才能实现现在用的是链接，打开一个新页面，怎么办？有的人用一个页面显示数据加载中，过几秒在跳转的方式，但是不想用这种假的 数据加载中 的方式
希望能等同updatepanel+progress控件那样
怎么写这个ajax呢？希望能详细点，不要一句话带过

是在新页面加载中,还是在本页显示加载中还有链接是target=_blank 还是window.open同不同域??如果是window.open可以用在弹出页执行到加载完毕以后window.opener.document.getElementById("divid").style.display="none";这样的方式解决....
