常用的Javascript语句（五）

来源：互联网发布：java sleep 编辑：程序博客网时间：2024/04/30 02:50

【1、最基本的弹出窗口代码】

其实代码非常简单：

<script language="＆#106avascript">

</script>
因为着是一段＆#106avascripts代码，所以它们应该放在<script language="＆#106avascript">标签和</script>之间。是对一些版本低的浏览器起作用，在这些老浏览器中不会将标签中的代码作为文本显示出来。要养成这个好习惯啊。
window.open (''page.html'') 用于控制弹出新的窗口page.html，如果page.html不与主窗口在同一路径下，前面应写明路径，绝对路径(http://)和相对路径(../)均可。用单引号和双引号都可以，只是不要混用。
这一段代码可以加入html的任意位置，<head>和</head>之间可以，<body>间</body>也可以，越前越早执行，尤其是页面代码长，又想使页面早点弹出就尽量往前放。

【2、经过设置后的弹出窗口】

下面再说一说弹出窗口的设置。只要再往上面的代码中加一点东西就可以了。
我们来定制这个弹出的窗口的外观，尺寸大小，弹出的位置以适应该页面的具体情况。
<script language="＆#106avascript">

</script>
参数解释：
<script language="＆#106avascript"> js脚本开始；
window.open 弹出新窗口的命令；
''page.html'' 弹出窗口的文件名；
''newwindow'' 弹出窗口的名字（不是文件名），非必须，可用空''''代替；
height=100 窗口高度；
width=400 窗口宽度；
top=0 窗口距离屏幕上方的象素值；
left=0 窗口距离屏幕左侧的象素值；
toolbar=no 是否显示工具栏，yes为显示；
menubar，scrollbars 表示菜单栏和滚动栏。
resizable=no 是否允许改变窗口大小，yes为允许；
location=no 是否显示地址栏，yes为允许；
status=no 是否显示状态栏内的信息（通常是文件已经打开），yes为允许；
</script> js脚本结束

【3、用函数控制弹出窗口】

下面是一个完整的代码。
<html>
<head>
<script language="＆#106avascript">

</script>
</head>
<body >
...任意的页面内容...
</body>
</html>
这里定义了一个函数openwin(),函数内容就是打开一个窗口。在调用它之前没有任何用途。
怎么调用呢？
方法一：<body > 浏览器读页面时弹出窗口；
方法二：<body > 浏览器离开页面时弹出窗口；
方法三：用一个连接调用：
<a href="#" _fcksavedurl=""#"" ＆#111nclick="openwin()">打开一个窗口</a>
注意：使用的“#”是虚连接。
方法四：用一个按钮调用：
<input type="button" ＆#111nclick="openwin()" ＆#118alue="打开窗口">

【4、同时弹出2个窗口】

对源代码稍微改动一下：
<script language="＆#106avascript">

</script>
为避免弹出的2个窗口覆盖，用top和left控制一下弹出的位置不要相互覆盖即可。最后用上面说过的四种方法调用即可。

注意：2个窗口的name(newwindows和newwindow2)不要相同，或者干脆全部为空。ok？

【5、主窗口打开文件1.htm，同时弹出小窗口page.html】

如下代码加入主窗口<head>区：
<script language="＆#106avascript">

</script>
加入<body>区：
<a href="1.htm" ＆#111nclick="openwin()">open</a>即可。

【6、弹出的窗口之定时关闭控制】

下面我们再对弹出的窗口进行一些控制，效果就更好了。如果我们再将一小段代码加入弹出的页面(注意是加入到page.html的html中，可不是主页面中，否则...)，让它10秒后自动关闭是不是更酷了？

首先，将如下代码加入page.html文件的<head>区：
<script language="＆#106avascript">
function closeit()
{settimeout("self.close()",10000) //毫秒}
</script>
然后，再用<body > 这一句话代替page.html中原有的<body>这一句就可以了。(这一句话千万不要忘记写啊！这一句的作用是调用关闭窗口的代码，10秒钟后就自行关闭该窗口。)

【7、在弹出窗口中加上一个关闭按钮】

<form>
<input type=''button'' ＆#118alue=''关闭'' ＆#111nclick=''window.close()''>
</form>

呵呵，现在更加完美了！

【8、内包含的弹出窗口-一个页面两个窗口】

上面的例子都包含两个窗口，一个是主窗口，另一个是弹出的小窗口。

通过下面的例子，你可以在一个页面内完成上面的效果。
<html>
<head>
<script language="＆#106avascript">
function openwin()
{openwindow=window.open("", "newwin", "height=250, width=250,toolbar=no,scrollbars="+scroll+",menubar=no";
//写成一行
openwindow.document.write("<title>例子</title>"
openwindow.document.write("<body bgcolor=#ffffff>"
openwindow.document.write("<h1>hello!</h1>"
openwindow.document.write("new window opened!"
openwindow.document.write("</body>"
openwindow.document.write("</html>"
openwindow.document.close()}
</script>
</head>
<body>
<a href="#" ＆#111nclick="openwin()">打开一个窗口</a>
<input type="button" ＆#111nclick="openwin()" ＆#118alue="打开窗口">
</body>
</html>
看看 openwindow.document.write()里面的代码不就是标准的html吗？只要按照格式写更多的行即可。千万注意多一个标签或少一个标签就会出现错误。记得用openwindow.document.close()结束啊。

【9、终极应用--弹出的窗口之cookie控制】

回想一下，上面的弹出窗口虽然酷，但是有一点小毛病(沉浸在喜悦之中，一定没有发现吧？)比如你将上面的脚本放在一个需要频繁经过的页面里(例如首页)，那么每次刷新这个页面，窗口都会弹出一次，是不是非常烦人？:-(有解决的办法吗？yes! ;-) follow me.

我们使用cookie来控制一下就可以了。

首先，将如下代码加入主页面html的<head>区：
<script>
function openwin()
{window.open("page.html","","width=200,height=200"}
function get_cookie(name)
{var search = name + "="
var return＆#118alue = "";
if (documents＆#46cookie.length > 0) {
offset = documents＆#46cookie.indexof(search)
if (offset != -1) {
offset += search.length
end = documents＆#46cookie.indexof(";", offset);
if (end == -1)
end = documents＆#46cookie.length;
return＆#118alue=unescape(documents＆#46cookie.substring(offset,end))
}
}
return return＆#118alue;
}
function loadpopup(){
if (get_cookie(''popped'')==''''){
openwin()
documents＆#46cookie="popped=yes"
}
}
</script>
然后，用<body >（注意不是openwin而是loadpop啊！）替换主页面中原有的<body>这一句即可。你可以试着刷新一下这个页面或重新进入该页面，窗口再也不会弹出了。真正的pop-only-once！

</style>
在这里输入你需要转换的格式，可以是JavaScript也可以是DHtml.

这个是输出格式的窗口:

广告JS代码效果大全
1.[普通效果]
    现在很多网站广告做的如火如荼，现在我就来介绍一下常见的对联浮动广告效果的代码使用方法，介绍的这种效果，在1024*768分辨率下正常显示，在800*600的分辨率下可以自动隐藏，以免遮住页面影响访问者浏览内容，下面就是实现效果所需代码：

var delta=0.015
var collection;
    function floaters() {
    this.items = [];
    this.addItem =
function(id,x,y,content)
    {
    document.write(''<DIV id=''+id+'' style="Z-INDEX: 0; POSITION: absolute; width:80px; height:60px;left:''+(typeof(x)==''string''?eval(x):x)+'';top:''+(typeof(y)==''string''?eval(y):y)+''">''+content+''</DIV>'');

    var newItem = {};
    newItem.object = document.getElementById(id);
    newItem.x = x;
    newItem.y = y;

    this.items[this.items.length] = newItem;
    }
    this.play =
function()
    {
    collection =
this.items
    setInterval(''play()'',10);
    }
    }
    function play()
    {
    if(screen.width<=800)
    {
    for(var i=0;i<collection.length;i++)
    {
    collection.object.style.display = ''none'';
    }
    return;
    }
    for(var i=0;i<collection.length;i++)
    {
    var followObj = collection.object;
    var followObj_x = (typeof(collection.x)==''string''?eval(collection.x):collection.x);
    var followObj_y = (typeof(collection.y)==''string''?eval(collection.y):collection.y);

    if(followObj.offsetLeft!=(document.body.scrollLeft+followObj_x)) {
    var dx=(document.body.scrollLeft+followObj_x-followObj.offsetLeft)*delta;
    dx=(dx>0?1:-1)*Math.ceil(Math.abs(dx));
    followObj.style.left=followObj.offsetLeft+dx;
    }

    if(followObj.offsetTop!=(document.body.scrollTop+followObj_y)) {
    var dy=(document.body.scrollTop+followObj_y-followObj.offsetTop)*delta;
    dy=(dy>0?1:-1)*Math.ceil(Math.abs(dy));
    followObj.style.top=followObj.offsetTop+dy;
    }
    followObj.style.display = '''';
    }
    }

    var theFloaters =
new floaters();
    theFloaters.addItem(''followDiv1'',''document.body.clientWidth-100'',0,''</a><br><a href=广告链接地址 target=_blank><img src=广告图片地址 width=100 height=400 border=0></a>'' target=_blank);
    theFloaters.addItem(''followDiv2'',0,0,''<br><a href=广告链接地址 target=_blank><img src=广告图片地址 width=100 height=400 border=0></a>'' target=_blank);
    theFloaters.play();

把上面的代码另存为一个JS文件，然后在想实现此效果的页面用调用即可！注意修改广告图片地址和连接地址！

    theFloaters.play();

   把上面的代码分别另存为两个JS文件，然后在想实现此效果的页面用

    <script type="text/javascript" language="javascript1.2" src="*.js"></SCRIPT>

    调用即可，*代表你另存的文件名！注意修改广告图片地址和连接地址！

把以上文件存为一个JS文件

在下面文件中引用即可

<style type="text/css">

</style>
<script language="javascript" src="test.js">
</script>


<body >
<div id="rotatorPlayer"></div>

<input type="button" name="play" value="开始播放"  disabled="True"/>
<input type="button" name="stops" value="暂停" />
<input type="button" name="backs" value="上一张"  disabled="true"/>
<input type="button" name="next" value="下一张" />
<input type="text" id="second" value="3" size="3" maxlength="2">
秒
<input type="button" value="设置时间"  />

<input name="image" type="text" size="65"/>

一个非常棒的播放器,可惜如果图片是非常大的话,那结果有点惨
