JSP 项目中涉及到一个聊天室,到网上找了一下,以前别人做过了很多种(包括Java ,C# ,PHP 等),但UI 层窗口大小都是固死了的,于是自己重新做了一个可以随窗体大小改变的的聊天室:
代码兼容:Firefox ,IE 6+ 时间:-6-13 晚从画图到代码完成一个个半小时
先看伪设计图: 参照附件 聊天室设计页面计算方式.JPG
下面UI 层代码:

呵呵,谢谢提醒,刚刚发现我贴的代码如果直接复制会产生很多空格,马山加一个截图和重新传一份代码。 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=GBK" /> <script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js"></script> <script type="text/javascript"> // 窗口大小 var winWidth = 0; var winHeight = 0; $(function(){ // 加载完成后 $(window).bind('load',init); // 当窗体大小改变后 $(window).bind('resize',function(){ init(); scrollToButtom(); }); // 设置内容层样式 $("#content").bind('mouseout',function(){ this.style.borderColor= '#ccc' }).bind('mouseover',function(){ this.style.borderColor= '#808080' }) $("#rightsidebar>ul>li").bind('click',function(){ $.each(this.parentNode.childNodes,function(i,j){ $(j).css({"color":"#000"}); }); $(this).css({"color":"#808080"}); document.getElementById('who').innerHTML = this.childNodes[0].childNodes[0].innerHTML; }).bind('mouseout',function(){ this.style.backgroundColor='#fff'; }).bind('mouseover',function(){ this.style.backgroundColor='#ddd'; }); }); // 初始化 function init(){ winWidth = getWindowScroll()["width"]; winHeight = getWindowScroll()["height"]; // 计算出 列表层的高度和高度 计算方式参照:设计图 var listViewHeight = winHeight - (8*2 + 1*2 + 3*2 + 102 + 27 + 3*2 + 2 + 16); var listViewLeft = winWidth - (8*2 + 1*2 + 3*2 + 282 + 3 + 2 + 3); // 做最小值处理 listViewLeft = listViewLeft > 280 ?
