mount=2>滚动信息
</marquee>
--------------------------------------------------------------------------------
20.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
--------------------------------------------------------------------------------
21.文字或图片弹出指定大小的窗口
在body中加入
<script language="JavaScript" type="text/JavaScript">
function MM_openBrWindow(theURL,winName,features) {window.open(theURL,winName,features);}
</script>
弹出代码
<a href="#" target="_self" onClick="MM_openBrWindow(’
windows01.htm’,’’,’width=550,height=380’)" width="550" height="380" border="0">图片或文字</a>
--------------------------------------------------------------------------------
22.跳转页面代码
<meta http-equiv="refresh" content="5;url=http://www.devdao.com">
--------------------------------------------------------------------------------
23.细线分隔线
<hr noshade size=0 color=#C0C0C0>
--------------------------------------------------------------------------------
24.网页中的自动换行
<td style="word-break:break-all">就搞定了。
完整的是
style="table-layout: fixed;WORD-BREAK: break-all; WORD-WRAP: break-word"
--------------------------------------------------------------------------------
25.消除ie6自动出现的图像工具栏，设置 GALLERYIMG属性为false或no .
<IMG SRC="mypicture.jpg" HEIGHT="100px" WIDTH="100px" GALLERYIMG="no">
--------------------------------------------------------------------------------
26.禁止页面正文内容被选取
<body oncontextmenu="return false" ondragstart="return false" onselectstart ="return false"
onselect="document.selection.empty()" oncopy="document.selection.empty()"
onbeforecopy="return
false"onmouseup="document.selection.empty()">
--------------------------------------------------------------------------------
27.不能点右键，不用CTRL+A，不能复制作!
<body oncontextmenu="window.event.returnValue=false"
onkeypress="window.event.returnValue=false"
onkeydown="window.event.returnValue=false"
onkeyup="window.event.returnValue=false"
ondragstart="window.event.returnValue=false"
onselectstart="event.returnValue=false">
</body>
--------------------------------------------------------------------------------
28.IE浏览器支持一个 Body 属性 bgproperties，它可以让背景不滚动:
<Body Background="图片文件" bgproperties="fixed">
--------------------------------------------------------------------------------
29.随机变换背景图象（一个可以刷新心情的特效）
<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>
--------------------------------------------------------------------------------
30.图片表单按钮
<form id="form1" name="form1" method="post" action="">
<img src="login.gif" width="62" height="22" onclick="document.form1.submit()" />
</form>
--------------------------------------------------------------------------------
31.左右阴影背景的CSS定义方法
body {
text-align:center;
background-repeat: repeat-y;
background-position: center;
background-image: url(../images/bg.jpg);
}
--------------------------------------------------------------------------------
32.划过链接 手型鼠标
style="cursor:hand"
--------------------------------------------------------------------------------
33.如何关闭层
<div id="Layer1"></div>
<a href="#" onClick="Layer1.style.display=’none’">关闭层</a>
--------------------------------------------------------------------------------
34.关闭窗口的脚本
<a href=javascript:close()>[关闭窗口]</a>
--------------------------------------------------------------------------------
35.如果文字过长,则将过长的部分变成省略号显示
<DIV STYLE="width: 120px; height: 50px; border: 1px solid blue;overflow: hidden; text-overflow:ellipsis">
<NOBR>就是比如有一行文字，很长，表格内一行显示不下.</NOBR>
</DIV>
--------------------------------------------------------------------------------
36.进入主页后自动最大化
<script>
self.moveTo(0,0)
self.resizeTo(screen.availWidth,screen.availHeight)
</script>
--------------------------------------------------------------------------------
37.凹陷文字
<div style="width:300px;padding:20px;overflow:hidden;word-wrap:break-word;word-break:break:all; font-size:12px; line-height:18px; background-color:#eeeeee;">
<font disabled>
怎么样，我凹下去了吧？<br>
你不想试试吗？<br>
<a href="http://www.devdao.com/">www.devdao.com</a></font>
</div>
--------------------------------------------------------------------------------
38.运行代码框
<script>
function Preview()
{var TestWin=open(’’);
TestWin.document.write(code.value);}
</script>
<textarea id=code cols=60 rows=15></textarea>
<br>
<button onclick=Preview() >运行</button>
-------------------------------------------------------------------------------
