如何使用jQuery刷新Bootstrap模态框

jquerytwitter-bootstrap

3

当我向下滚动模态框，然后关闭模态框，再次打开该模态框时，将显示上次的滚动位置。

为了更好地理解，请阅读以下内容

当前，如果我们向下滚动 -> 关闭它 -> 再次打开它，它将显示滚动的最后访问位置

应该从顶部显示列表。

当您关闭模型时，请编写一个 jQuery 函数，使模型的滚动条回到顶部（0）。 - HaSnen Tai

完成了伙计，我刚刚在关闭按钮的onclick事件中添加了代码 -> function scrolltop() {

    $("#logbody").scrollTop(0);

}

使用 Scroll Top，你可以轻松地实现这一点。

当你关闭模型时，编写一个 jQuery 函数，使模型的滚动条返回到 0。

就像这样：

$('.close').click(function(){
        $('.modal-body').scrollTop(0);
    });

给一个名为“close”的类，与关闭按钮相似，这样就可以正常工作了。
