异步回发后如何保持整页滚动位置

asp.net有一个名为@page directive的属性 MaintainScrollPositionOnPostBack

希望这会有帮助

只需在脚本管理器之后添加它。它在所有浏览器中都对我有效

<script type="text/javascript">
    var prm = Sys.WebForms.PageRequestManager.getInstance();
    prm.add_beginRequest(beginRequest);
    function beginRequest()
    {
        prm._scrollPosition = null;
    }
</script>

你可以用客户的方式:

$(document).ready(function () {
    $(window).on('beforeunload', function () {
        document.cookie = "keepscroll=" + $(window).scrollTop();
    });
    var cs = document.cookie ? document.cookie.split(';') : [];
    var i = 0, cslen = cs.length;
    for (; i < cs.length; i++) {
        var c = cs[i].split('=');
        if (c[0].trim() == "keepscroll") {
            $(window).scrollTop(parseInt(c[1]));
            break;
        }
    }
});

如果您不是jQuery的朋友,那么您可以尝试以下方法:

window.onbeforeunload = function () {
    document.cookie = "keepscroll=" + document.body.scrollTop;
};
var keepscroll = window.setTimeout(function () {
    var cs = document.cookie ? document.cookie.split(';') : [];
    var i = 0, cslen = cs.length;
    for (; i < cs.length; i++) {
        var c = cs[i].split('=');
        if (c[0].trim() == "keepscroll") {
            window.scrollTo(0, parseInt(c[1]));
            break;
        }
    }
    window.clearTimeout(keepscroll);
    keepscroll = null;
}, 100);
