37. 各种样式的光标auto :标准光标default :标准箭头hand :手形光标wait :等待光标text :I形光标vertical-text :水平I形光标no-drop :不可拖动光标not-allowed :无效光标help :?帮助光标all-scroll :三角方向标move :移动标crosshair :十字标e-resizen-resizenw-resizew-resizes-resizese-resizesw-resize38.页面进入和退出的特效进入页面 <meta http-equiv= "Page-Enter " content= "revealTrans(duration=x, transition=y) ">
推出页面 <meta http-equiv= "Page-Exit " content= "revealTrans(duration=x, transition=y) ">
这个是页面被载入和调出时的一些特效。duration表示特效的持续时间,以秒为单位。transition表示使用哪种特效,取值为1-23:
0 矩形缩小1 矩形扩大2 圆形缩小3 圆形扩大4 下到上刷新5 上到下刷新6 左到右刷新7 右到左刷新8 竖百叶窗9 横百叶窗10 错位横百叶窗11 错位竖百叶窗12 点扩散13 左右到中间刷新14 中间到左右刷新15 中间到上下16 上下到中间17 右下到左上18 右上到左下19 左上到右下20 左下到右上21 横条22 竖条23 以上22种随机选择一种39.在规定时间内跳转<META http-equiv=V= "REFRESH " content= "5;URL=http://www.williamlong.info ">
40.网页是否被检索<meta name= "ROBOTS " content= "属性值 ">
其中属性值有以下一些:
属性值为 "all ": 文件将被检索,且页上链接可被查询;属性值为 "none ": 文件不被检索,而且不查询页上的链接;属性值为 "index ": 文件将被检索;属性值为 "follow ": 查询页上的链接;属性值为 "noindex ": 文件不检索,但可被查询链接;属性值为 "nofollow ": 文件不被检索,但可查询页上的链接。
最大化窗口?
<script language= "JavaScript ">
<!--self.moveTo(0,0)self.resizeTo(screen.availWidth,screen.availHeight)//-->
</script>
解决问题:由于层与下拉框之间的优先级是:下拉框 > 层,因此在显示的时候,会因为优先级的次序而会出现如上问题。(如果几个元素都是层的话,我们可以通过层的 z-index 属性来设置)解决办法就是:给层中放一个优先级比下拉框更高的元素(iframe),从而解决此问题!具体解决代码如下: <div id= "menu " style= "position:absolute; visibility:hidden; top:20px; left:20px; width:100px; height:200px; background-color:#6699cc; ">
<table>
<tr> <td> item 1 </td> </tr>
<tr> <td> item 2 </td> </tr>
<tr> <td> item 3 </td> </tr>
<tr> <td> item 4 </td> </tr>
<tr> <td> item 5 </td> </tr>
</table>
<iframe src= "/blog/javascript:false " style= "position:absolute; visibility:inherit; top:0px; left:0px; width:100px; height:200px; z-index:-1; filter= 'progid:DXImageTransform.Microsoft.Alpha(style=0,opacity=0) '; "> </iframe>
</div>
<a href= "# " onclick= "document.getElementById( 'menu ').style.visibility= 'visible ' "> menu </a>
<form>
<select> <option> A form selection list </option> </select>
</form>
输入框也可以做的很漂亮了<div align= "center "> <input type= "hidden " name= "hao " value= "yes ">
外向数: <inputname=answerstyle= "color: rgb(255,0,0); border-left: medium none; border-right: medium none; border-top: medium none; border-bottom: 1px solid rgb(192,192,192) ">
没回答的题数: <inputname=unanswer id= "unanswer "style= "color: rgb(255,0,0); border-left: medium none; border-right: medium none; border-top: medium none; border-bottom: 1px solid rgb(192,192,192) ">
<br/>
总得分:
<inputname=score id= "score "style= "color: rgb(255,0,0); border-left: medium none; border-right: medium none; border-top: medium none; border-bottom: 1px solid rgb(192,192,192) ">
结    论:
<inputname=xgjg id= "xgjg "style= "color: rgb(255,0,0); border-left: medium none; border-right: medium none; border-top: medium none; border-bottom: 1px solid rgb(192,192,192) ">
<br/>
<br/>
<input onClick=processForm(this.form) style= "FONT-FAMILY: 宋体; FONT-SIZE: 9pt " type=button value=查看结果 name= "button ">
<input type= "reset " name= "Submit " value= "重做 ">
</div>
注意:修改 <body> 为 <body onload= "max.Click() "> 即为打开最大化窗口,而如果改为 <body onload= "min.Click() "> 就变为窗口一打开就最小化<object id= "min " type= "application/x-oleobject " classid= "clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11 ">
<param name= "Command " value= "Minimize ">
</object> <object id= "max " type= "application/x-oleobject " classid= "clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11 ">
<param name= "Command " value= "Maximize ">
</object>
</body>
页面自动刷新(说明)当你做网页时,是不是有的时候想让你的网页自动不停刷新,或者过一段时间自动跳转到另外一个你自己设定的页面?其实实现这个效果非常地简单,而且这个效果甚至不能称之为特效。你只要把如下代码加入你的网页中就可以了。
1,页面自动刷新:把如下代码加入 <head> 区域中 <meta http-equiv= "refresh " content= "20 "> ,其中20指每隔20秒刷新一次页面.
2,页面自动跳转:把如下代码加入 <head> 区域中 <meta http-equiv= "refresh " content= "20;url=http://www.williamlong.info "> ,其中20指隔20秒后跳转到http://www.williamlong.info页面。
页面自动关闭5000是指时间 <body onLoad= "setTimeout(window.close, 5000) ">
弹出窗口自动关闭10秒后弹出窗口自动关闭 注意:在新的tan.htm的body中要加 <onLoad= "closeit() ">
head<script language= "JavaScript ">
<!--var gt = unescape( '%3e ');var popup = null;var over = "Launch Pop-up Navigator ";popup = window.open( ' ', 'popupnav ', 'width=225,height=235,resizable=1,scrollbars=auto ');if (popup != null) {if (popup.opener == null) {popup.opener = self;}
popup.location.href = 'tan.htm ';}
// -->
</script>
<body> 注意:这段代码是在新建文件中的<script language= "JavaScript ">
function closeit()</script>
这个可不是 <iframe> (引用)呀。是直接调用的。以下代码加入 <body> 区域<object type= "text/x-scriptlet " width= "800 " height= "1000 " data= "../index.htm ">
</object>
