一.在需要加入浮动框的页面中加入如下css代码：
<!-- 浮动窗口样式css begin --> <style type="text/css"> #msg_win { border: 1px solid #A67901; background: #EAEAEA; width: 240px; position: absolute; right: 0; font-size: 12px; font-family: Arial; margin: 0px; display: none; overflow: hidden; z-index: 99; } #msg_win .icos { position: absolute; top: 2px; *top: 0px; right: 2px; z-index: 9; } .icos a { float: left; color: #833B02; margin: 1px; text-align: center; font-weight: bold; width: 14px; height: 22px; line-height: 22px; padding: 1px; text-decoration: none; font-family: webdings; } .icos a:hover { color: #fff; } #msg_title { background: #BBDEF6; border-bottom: 1px solid #A67901; border-top: 1px solid #FFF; border-left: 1px solid #FFF; color: #000; height: 25px; line-height: 25px; text-indent: 5px; } #msg_content { margin: 5px; margin-right: 0; width: 230px; height: 126px; overflow: hidden; } </style> <!-- 浮动窗口样式css end -->
二.js代码(注意：该代码要添加整个页面最后，目的是页面加载完成时加载它)
<!-- 浮动窗口js，必须要放置到最后 begin--> <script type="text/javascript"> var Message={ set: function() {//最小化与恢复状态切换 var set=this.minbtn.status == 1?[0,1,'block',this.char[0],'最小化']:[1,0,'none',this.char[1],'展开']; this.minbtn.status=set[0]; this.win.style.borderBottomWidth=set[1]; this.content.style.display =set[2]; this.minbtn.innerHTML =set[3] this.minbtn.title = set[4]; this.win.style.top = this.getY().top; }, close: function() {//关闭 this.win.style.display = 'none'; window.onscroll = null; }, setOpacity: function(x) {//设置透明度 var v = x >= 100 ? '': 'Alpha(opacity=' + x + ')'; this.win.style.visibility = x<=0?'hidden':'visible';//IE有绝对或相对定位内容不随父透明度变化的bug this.win.style.filter = v; this.win.style.opacity = x / 100; }, show: function() {//渐显 clearInterval(this.timer2); var me = this,fx = this.fx(0, 100, 0.1),t = 0; this.timer2 = setInterval(function() { t = fx(); me.setOpacity(t[0]); if (t[1] == 0) {clearInterval(me.timer2) } },10); }, fx: function(a, b, c) {//缓冲计算 var cMath = Math[(a - b) > 0 ? "floor": "ceil"],c = c || 0.1; return function() {return [a += cMath((b - a) * c), a - b]} }, getY: function() {//计算移动坐标 var d = document,b = document.body, e = document.documentElement; var s = Math.max(b.scrollTop, e.scrollTop); var h = /BackCompat/i.test(document.compatMode)?b.clientHeight:e.clientHeight; var h2 = this.win.offsetHeight; return {foot: s + h + h2 + 2+'px',top: s + h - h2 - 2+'px'} }, moveTo: function(y) {//移动动画 clearInterval(this.timer); var me = this,a = parseInt(this.win.style.top)||0; var fx = this.fx(a, parseInt(y)); var t = 0 ; this.timer = setInterval(function() { t = fx(); me.win.style.top = t[0]+'px'; if (t[1] == 0) { clearInterval(me.timer); me.bind(); } },10); }, bind:function (){//绑定窗口滚动条与大小变化事件 var me=this,st,rt; window.onscroll = function() { clearTimeout(st); clearTimeout(me.timer2); me.setOpacity(0); st = setTimeout(function() { me.win.style.top = me.getY().top; me.show(); },600); }; window.onresize = function (){ clearTimeout(rt); rt = setTimeout(function() {me.win.style.top = me.getY().top},100); } }, init: function() {//创建HTML function $(id) {return document.getElementById(id)}; this.win=$('msg_win'); var set={minbtn: 'msg_min',closebtn: 'msg_close',title: 'msg_title',content: 'msg_content'}; for (var Id in set) {this[Id] = $(set[Id])}; var me = this; this.minbtn.onclick = function() {me.set();this.blur()}; this.closebtn.onclick = function() {me.close()}; this.char=navigator.userAgent.toLowerCase().indexOf('firefox')+1?['_','::','×']:['0','2','r'];//FF不支持webdings字体 this.minbtn.innerHTML=this.char[0]; this.closebtn.innerHTML=this.char[2]; setTimeout(function() {//初始化最先位置 me.win.style.display = 'block'; me.win.style.top = me.getY().foot; me.moveTo(me.getY().top); },0); return this; } }; Message.init(); </script> <!-- 浮动窗口js end-->
三.html代码(注意：该代码要放置到body的最后)
<!-- 浮动窗口html代码 begin --> <hr> <div> <div> <a title="最小化" href="javascript:void 0">_</a><a title="关闭" href="javascript:void 0">×</a> </div> <div>设备运行情况--></div> <div> ${commonMsg.devRun } </div> </div> <!-- 浮动窗口html代码 end -->
