Js_特效II

字号缩放
　　让文字大点，让更多的用户看的更清楚。(也可以把字体变为百分比来实现)
<script type="text/javascript">
function doZoom(size)
{document.getElementById('zoom').style.fontSize=size+'px';}
</script>
<span id="zoom">需要指定大小的文字</span> 网页教学网http://www.webjx.com
<a href="javascript:doZoom(16)">大</a> <a href="javascript:doZoom(14)">中</a> <a href="javascript:doZoom(12)">小</a>

　　跳转菜单新窗口
<select name="select" onchange="window.open(this.options[this.selectedIndex].value)">
<option value="http://www.microsoft.com/ie"> Internet Explorer</option>
<option value="http://www.microsoft.com"> Microsoft Home</option>
<option value="http://msdn.microsoft.com"> Developer Network</option>
</select>

　　添加到收藏夹和设为首页

　　添加到收藏夹
<a href="javascript:window.external.addFavorite('http://链接','说明');">添加到收藏夹</a>

　　设为首页
<a href=# onclick=this.style.behavior='url(#default#homepage)';this.setHomePage ('http://链接');>设为首页</a>

　　打开窗口即最大化
<script language="JavaScript">

</script>

　　加入背景音乐
<bgsound src="mid/windblue[1].mid" loop="-1"> 只适用于IE
<embed src="music.mid" autostart="true" loop="true" hidden="true">
对Netscape ,IE 都适用

　　防止点击空链接时，页面往往重置到页首端
　　代码“javascript:void(null)”代替原来的“#”标记，也可以用“#nogo”来代替啊？

　　自动换行
style="table-layout: fixed;WORD-BREAK: break-all; WORD-WRAP: break-word"
　　只对IE有用...FF的话用overflow:hidden来解决，不至于影响美观

1.不同时间段显示不同问候语

　　〈script Language="Javascript"〉　　〈!-- 　　var text=""; day = new Date( ); time = day.getHours( ); 　　if (( time〉=0) && (time 〈 7 )) 　　　　text="夜猫子，要注意身体哦! " 　　if (( time 〉= 7 ) && (time 〈 12)) 　　　　text="今天的阳光真灿烂啊，你那个朋友呢?" 　　if (( time 〉= 12) && (time 〈 14)) 　　　　text="午休时间。您要保持睡眠哦!" 　　if (( time 〉=14) && (time 〈 18)) 　　　　text="祝您下午工作愉快! " 　　if ((time 〉= 18) && (time 〈= 22)) 　　　　text="您又来了，可别和MM聊太久哦!" 　　if ((time 〉= 22) && (time 〈 24)) 　　　　text="您应该休息了!" 　　document.write(text) 　　//---〉　　〈/script〉

　　2.慢慢变大的窗口

　　〈script Language="Javascript"〉　　〈!-- 　　var Windowsheight=100 　　var Windowswidth=100 　　var numx=5 　　function openwindow(thelocation){ 　　temploc=thelocation 　　if 　　(!(window.resizeTo&&document.all)&&!(window.resizeTo&&document.getElementById)) 　　{ 　　　　window.open(thelocation) 　　　　return 　　} 　　windowsize=window.open("","","scrollbars") 　　windowsize.moveTo(0,0) 　　windowsize.resizeTo(100,100) 　　tenumxt() 　　} 　　function tenumxt(){ 　　if (Windowsheight〉=screen.availHeight-3) 　　　　numx=0 　　windowsize.resizeBy(5,numx) 　　Windowsheight+=5 　　Windowswidth+=5 　　if (Windowswidth〉=screen.width-5) 　　{ 　　　　windowsize.location=temploc 　　　　Windowsheight=100 　　　　Windowswidth=100 　　　　numx=5 　　　　return 　　} 　　setTimeout("tenumxt()",50) 　　} 　　//--〉　　〈/script〉　　〈p〉〈a href="javascript:openwindow('http://www.ccjol.com')"〉进入〈/a〉

　　3.改变IE地址栏的IE图标

　　我们要先做一个16*16的icon(图标文件)，保存为index.ico。把这个图标文件上传到根目录下并在首页〈head〉〈/head〉之间加上如下代码：　　〈link REL = "Shortcut Icon" href="index.ico"〉

　　4.让网页随意后退

　　〈a href="javascript:history.go(-X)"〉X〈/a〉 //把X换成你想要后退在页数　　 //把“-”变成“+”就为前进

　　5.鼠标指向时弹出信息框

　　在〈body〉〈/body〉之间加上如下代码：　　〈a href onmouseover="alert('弹出信息!')"〉显示的链接文字〈/a〉

　　6.单击鼠标右键弹出添加收藏夹对话框

　　在〈body〉〈/body〉之间加上如下代码：　〈script Language=Javascript〉 if (document.all) 　　document.body.onmousedown=new Function("if (event.button==2||event.button==3) 　　window.external.addFavorite('您的网址','您的网站名称)") 　　〈/script〉

　　7.随机变换背景图象(一个可以刷新心情的特效)

　　在〈head〉〈/head〉之间加上如下代码：　　〈script Language="Javascript"〉　　image = new Array(4); //定义image为图片数量的数组　　image [0] = 'tu0.gif' //背景图象的路径　　image [1] = 'tu1.gif' 　　image [2] = 'tu2.gif' 　　image [3] = 'tu3.gif' 　　image [4] = 'tu4.gif' 　　number = Math.floor(Math.random() * image.length); 　　document.write("〈BODY BACKGROUND="+image[number]+"〉"); 　　〈/script〉

　　8.表格的半透明显示效果

　　〈head〉　　〈style〉　　.alpha{filter: Alpha(Opacity=50)} //50表示50%的透明度　　〈/style〉〈/head〉　　〈body〉　　〈table border="1" width="100" height="62" class="alpha" bgcolor="#F2A664" 〉　　〈tr〉　　〈td width="100%" height="62"〉　　〈div align="center"〉很酷吧!〈/div〉　　〈/td〉　　〈/tr〉　　〈/table〉〈/body〉

for(var i=0; i<o.length-1; i++)if(o[i][c]!="w")w.appendChild(o[i]),i--;
(window.onresize = function(){
  w.style.width = d.documentElement.clientWidth + "px";
  w.style.height = d.documentElement.clientHeight + "px";
})();
}

},15);
})(document.getElementById("w"));
</script>
</html>

　3、让select控件可以自定义边框
<style>
.box2{border:1px solid #00ff00;180px;height:17px;clip:rect(0px,179px,16px,0px);overflow:hidden;}
select{position:relative;left:-2px;top:-2px;font-size:12px;183px;line-height:14px;border:0px;color:#909993;}
</style>
<div class="box2"><select id=idselect1 onchange="select1();" hidefocus>
<option selected>网页名</option>
<option>网页制作</option>
<option>媒体动画</option>
<option>网站运营<option>
</select></div>

       4、CSS圆角
<html xmlns:v>
<head>
<style>
v:* {behavior: url(#default#VML);}
</style>
</head>
<body>
<v:RoundRect style="position:relative;200;height:100px">
<v:shadow on="T" type="single" color="#b3b3b3" offset="5px,5px"/>
<v:textbox style="font-size:12px">css实现真正的圆角表格</v:textbox>
</v:RoundRect>
</body>
</html>

能够根据图片html代码自动生成右下角的数字导航按钮。

一句话函数调用，实现图片切换特效。

引用:

picChange("图片ul列表的id" , 切换图片的方法引用 , 图片切换时间 , 图片移动方向);

可扩展的封装方式，方便实现不同特效，源码中给出了淡出效果，和移出效果的实现方式。

使用方法示例：

引用:

//直接切换效果
picChange("picChange");
//淡出效果
picChange("picChange",fade,500);
//向上移出效果
picChange("picChange",move,500,"up");
//向下移出效果
picChange("picChange",move,500,"down");
//向左移出效果
picChange("picChange",move,500,"left");
//向右移出效果
picChange("picChange",move,500,"right");

图片随机显示是一个应用非常广泛的技巧。比如随机banner的显示，当你进入一个网站时它的banner总是不同的，或者总有内容不同的提示（tips)，大家在网上浏览时会经常发现这样的例子。使用这种技术，不但能在一定的空间里放入更多的内容，还可以给人一种经常更新的假象喔。

怎么样心动了吧？其实只要你有一点点html和javascript 的基础，一切都是这么简单。follow me,让我们来看看她随机的奥密。

让我们从一个简单的例子开始吧。平常我们在页面中加入图片都是用<img src="图片">来完成。如果我们要随机显示3张不同的图片就要对这句代码进行小小的修改，首先加入<script>标记：

以下是引用片段：
<script language=javascript></script>
然后在这段标记内把<img src="图片">用document.write("")的型式放进去，就成了
document.write("<img src=图片>")

现在我们来完成最关建的一段：

以下是引用片段：
id=Math.round(Math.random()*2)+1

这样取得随机数为1,2,3将你要显示的图片改名为1.gif,2.gif,3.gif，ok！最后的代码是：

以下是引用片段：
<script language=javascript>
id=Math.round(Math.random()*2)+1
document.write("<img src="+id+".gif>")
</script>

试一下，是不是不错？那如果我的每一张图片都对应了一个超链接该怎么办呢？
我们还是来假设一下有3张图片，1.gif,2.gif,3.gif,分别对应的链接是url1,url2,url3。
为了让图片和链接一一对应，我们要设置一个数组image来放置链接的地址，如下：

以下是引用片段：
var image=new Array(3)
image.length=3
image[1]="url1"
image[2]="url2"
image[3]="url3"

为了将与图片对应的链接取出来，我们还要定义一个数组imageurl=image[id]
原理是这样的：
当页面被读入时，取一个随机数，假设是2即id=2,那么如上我们可轻松的完成2.gif在页面的显示。然后我们可以看到：imageurl=image[2]而image[2]="url2"，剩下的事就好办了。完整的代码如下：

以下是引用片段：
<script language=javascript>
var image=new Array(3)
image.length=3
image[1]="url1"
image[2]="url2"
image[3]="url3"
id=Math.round(Math.random()*2)+1
imageurl=image[id]
document.write("<a href="+bannerurl+">"+"<img src="+id+".gif>")
</script>

朋友，“天上掉陷饼”都听说过吧？呵呵，陷饼它算个么，今天教你一个天上掉￥的招儿，并且～～哗啦啦地掉！哈～哈～哈，来吧^_*

实现跑马灯的方法很多，本文详细介绍JavaScript/JS实现标题栏跑马灯。

　　将下代码copy入你网页的和中的合适地方即可。

以下是引用片段：
<SCRIPT LANGUAGE=JAVASCRIPT>

</SCRIPT>

　　将你Html文件的改为如下：

以下是引用片段：
<BODY onload="window.setTimeout('titleScroll()', 500)">

　　注：如果您象我一样把它放在窗口中，请将document.title改为parent.document.title

function cls_marquee(id,id1,id2,sp){
    this.obj_id=id;
    this.obj_id1=id1;
    this.obj_id2=id2;
    this.speed=sp;
    eval(this.obj_id2+".innerHTML="+this.obj_id1+".innerHTML");

     function Marquee(){
       if(eval(id2).offsetTop-eval(id).scrollTop<=0)
              eval(id).scrollTop-=eval(id1).offsetHeight
          else{
              eval(id).scrollTop++
            }
            }
         var MyMar=setInterval(Marquee,sp)
         eval(this.obj_id).onmouseover=function() {clearInterval(MyMar)}
         eval(this.obj_id).onmouseout=function() {MyMar=setInterval(Marquee,sp)}
}
