jQuery Custom Content Scroller不会滚动到底部

Question

我使用mCustomScrollbar作为页面上的元素,有时会重新加载.这是一个消息视图,当用户点击另一个对话时,会加载此对话的消息.但是,当我想在加载它之后滚动到底部,因为最新的消息在底部,它滚动到底部但是在底部以上几个像素("一些"可以在10到200px之间随机).

以下是一个简化示例:

// code to load another conversation
$(".conversations .conversation").click(function (e) {
    var $this = $(this);
    $.ajax({
        url: W.sprintf('/messages/%s/fetch', $this.attr("data-cid")),
        dataType: 'html'
    }).done(function(data) {
        $('.main_pane.messages').html(data);
        // a function call to set the hight of .main_list.messages goes here
        $(".main_list.messages").mCustomScrollbar(W.scroll_prefs);
        $(".main_list.messages").mCustomScrollbar("scrollTo", "bottom");
        // also tried adding an element at bottom and scrolling to this
        // and scrollTo Number.MAX_VALUE
        // also tried putting the two mCustomScrollbar lines both into
        // setTimeout()
    });
});

<!-- this is what gets loaded -->
#conversation
  .head
    -# some foo
  .conv_body
    .main_list.messages.custom-scroll.hide-scrollbar.start-bottom
      -# basically a bunch of these below
      .listelem.msg
        .left
          = image_tag(user.avatar.image(:icon), size: avatar_size(:icon))
        .right
          %span.datetime= fmt_time(msg[:datetime], :time)
        .middle
          .name= link_to(user.login, user)
          .text= msg[:text]
    #new_message_container.main_input.open.threeline
      = form_for(@message) do |f|
        -# ...

CSS:只是一些边距和填充,颜色和东西,没有什么花哨的

我有同样的问题,首先调用更新,然后在调用scrollTo底部之前添加超时1000来解决它

$('#commentArea .mCSB_container ').append('<span class="oneComment">'+outputText+'</span><span class="commentBreaker"></span>');
$("#commentArea").mCustomScrollbar("update");
    setTimeout(function(){
        $("#commentArea").mCustomScrollbar("scrollTo","bottom");
    },1000);
