jQuery Perfect Scroll - Set Scrollbar to the Bottom of the Container
提问by Jason Biondo
I have just installed perfect scroll, the jQuery plugin, and it works great but I can't find a parameter to start the content at the bottom of my div. I want to have to scroll up on page load, not to have to scroll down.
我刚刚安装了完美的滚动,jQuery 插件,它工作得很好,但我在我的 div 底部找不到启动内容的参数。我想在页面加载时向上滚动,而不是向下滚动。
Normally with jQuery I would just do:
通常使用 jQuery 我只会做:
$(nav_message_list).prop({ scrollTop: $(nav_message_list).prop("scrollHeight")});
But that seems to have no effect.
但这似乎没有效果。
Current code:
当前代码:
$(".chat_person").click(function ()
{
if (!$(".chat_content_wrap").is(":visible"))
{
$(".chat_content_wrap").fadeIn(300, function ()
{
$('#message_list').perfectScrollbar('update');
$(nav_message_list).prop({ scrollTop: $(nav_message_list).prop("scrollHeight")});
});
}
});
$("#message_list").perfectScrollbar();

I haven't used the plugin before but based on the docs at https://github.com/noraesae/perfect-scrollbar
我之前没有使用过该插件,但基于https://github.com/noraesae/perfect-scrollbar上的文档
The code you should need is:
您应该需要的代码是:
$("#message_list").scrollTop( $( "#message_list" ).prop( "scrollHeight" ) );
$("#message_list").perfectScrollbar('update');
The $ selectors may be wrong since I can't see you HTML code.
$ 选择器可能是错误的,因为我看不到您的 HTML 代码。
