delphi 自动滚动到最底端scroll的相关文章

基于JQuery实现滚动到页面底端时自动加载更多信息

基于JQuery实现滚动到页面底端时自动加载更多信息关键代码: 代码如下: var stop=true; $(window).scroll(function(){ totalheight = parseFloat($(window).height()) + parseFloat($(window).scrollTop()); if($(document).height() <= totalheight){ if(stop==true){ stop=false; $.post("ajax.

判断滚动条是否滚动到最底端

条件: $("div")[0].scrollTop + $("div").height() == $("div")[0].scrollHeight 完整滚动事件: var nScrollHight = 0; var nScrollTop = 0; var nDivHight = $(".div").height(); $(".div").scroll(function() { nScrollH

使用scrollpagination实现页面底端自动加载无需翻页功能

当阅读到页面最底端的时候,会自动显示一个"加载中"的功能,并自动从服务器端无刷新的将内容下载到本地浏览器显示. 这样的自动加载功能是如何实现的?jQuery的插件 ScrollPagination 可以帮助实现这个功能. 这里是ScrollPagination 功能的原型化代码, $(function() { $('#content').scrollPagination({ 'contentPage': 'democontent.html', // the page where you

让DIV的滚动条自动滚动到最底部 - 3种方法

要制作一个在线聊天的程序,在做最后的修饰时,需要对获得的信息即时滚动以保证用户总能看到最新消息. 聊天程序是基于AJAX设计的,没有用框架,消息容器是一个DIV,所以问题就在于如何控制DIV的滚动条. 但同样的代码拿到我这里却完全失效,又仔细查了下资料说XHTML标准下scrollTop的值恒为0,解决办法是使用 document.documentElement.scrollTop代替document.body.scrollTop,讲了半天所解决的是整个页面的滚动条.这个方法我是用不了了,因为

自动滚动的Textview

又到了写博博的时候了!大家还好吧! 开始做机顶盒了,所以这里就有很多的界面需要做成一个自动化的界面.因为遥控盒手机触摸毕竟不一样咯!这里而且要方便大众的视觉体验的话,我们必须要考虑到这些因素.当然,我觉着,这次的自动滚动效果一定对大家也很有帮助的哦! 我们只要写一个类来继承我布局文件里面写的一个TextView就ok啦. package com.example.myscroltextview.view; import java.util.ArrayList; import android.con

C# ListBox 自动滚动到底部方法:

在ListBox中添加一条记录(ListBox.Items.Add方法)后,滚动条会自动回到顶部.我们可能更希望它自动滚动到底部,简要介绍几种方法. 方法一: 1 this.listBox1.Items.Add("new line"); 2 this.listBox1.SelectedIndex = this.listBox1.Items.Count - 1; 3 this.listBox1.SelectedIndex = -1; 在添加记录后,先选择最后一条记录,滚动条会自动到底部,

课堂笔记-----页面的自动滚动效果

页面的自动滚动效果,可由javascript来实现, 但是有一个html标签 - <marquee></marquee>可以实现多种滚动效果,无需js控制. 使用marquee标记不仅可以移动文字,也可以移动图片,表格等. 语法:<marquee >...</marquee>: 说明:在标记之间添加要进行滚动的内容. 重要属性: 1.滚动方向direction(包括4个值:up. down. left和 right) 语法:<marquee direc
