博客右下角的漂浮窗口使用JavaScript实现,另外考虑到会经常修改广告代码部分,所以使用了Iframe框架,广告代码部分便使用独立的Html文件,这样方便管理。
第一步
在网站目录"wp-content"(也可是其它目录)中新建文件夹"js",在文件夹中新建文件"pf.js",打开粘贴下面的代码:
document.write(‘<div id="msg_win"
style="display:block;top:490px;visibility:visible;opacity:1;"><div
class="icos"><a id="msg_min" title="最小化" href="javascript:void
0">_</a><a id="msg_close" title="关闭" href="javascript:void
0">×</a></div><div id="msg_title">赞助</div><div
id="msg_content"><iframe src="http://yangjinyou.com/ad/sougouad1.html"
frameborder="0" marginwidth="0" marginheight="0" width="205"
height="205"></iframe></div></div>‘);
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],’恢复’];
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?[‘_‘,‘::‘,‘ב]:[‘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();
除第一行document.write后面的内容,其它都不用管,我这里是显示一个200*200的广告(在根目录下建立ad文件夹,新建文件sougouad1.html,将广告代码放入),如果需要显示的其实尺寸,第一行iframe这里需要修改;
第二步
打开主题样式表文件style.css,在最后面加入如下代码:
#msg_win{border:1px solid #bbbbbb;background:#eeeeee;width:204px;position:absolute;right:3px;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:#FFFFFF;margin:1px;text-align:center;text-decoration:none;font-family:webdings;}
.icos a:hover{color:#fff;}
#msg_title{background:#eeeeee;border-bottom:1px solid #666666;border-top:1px solid #FFFFFF;border-left:2px solid #FFFFFF;color:#000;height:20px;line-height:20px;text-indent:5px;}
#msg_min{color:#000;}
#msg_close{color:#000;}
#msg_content{margin:2px;width:200px;height:200px;overflow:hidden;}
.wp_syntax table td.line_numbers{background:none; border-right:3px solid skyblue; width:24px}修改弹出窗口样式,上面这个适合200*200的图片显示,效果见我网站第三步
我不希望广告代码影响到网页主体部分加载速度太多,所以第三步调用我将代码加</html>后面,这个</html>一般在主题文件夹的footer.php文件中,打开找到</html>标签,一般就是最后一行,另起一行加入如下代码:
<script language="JavaScript" src="http://www.fengmiq.com/wp-content/js/pf.js"></script>
