20. <div> <span>& <layer>的区别?
1

|
<div>(division)用来定义大段的页面元素,会产生转行
<span>用来定义同一行内的元素,跟 <div>的唯一区别是不产生转行
<layer>是ns的标记,ie不支持,相当于 <div>

两个都去掉?更简单了
<body scroll=
"no"

</script>
============
<html>
<head>
<script language=
"LiveScript"
>
function
WinOpen() {
msg=open(
""
,
"DisplayWindow"
,
"toolbar=no,directories=no,menubar=no"
);
msg.***(
" <HEAD> <TITLE>哈 罗! </TITLE> </HEAD>"

}
</script>
</head>
<body>
<form>
<input type=
"button"
name=
"Button1"
value=
"Push me"
</form>
</body>
</html>
==============
一、在下面的代码中,你只要单击打开一个窗口,即可链接到赛迪网。而当你想关闭时,只要单击一下即可关闭刚才打开的窗口。
代码如下:
<SCRIPT language=
"JavaScript"
>
<!--
function
openclk() {
another=open(‘1000){
this
.resized=
true
;
this
.style.width=1000;}
" align=absMiddle border=0>http://www.ccidnet.com‘,‘NewWindow‘);
}
function closeclk() {
another.close();
}
//-->
</SCRIPT>
<FORM>
<INPUT TYPE="
BUTTON
" NAME="
open
" value="
/打开一个窗口
" onClick="
openclk()
">
<BR>
<INPUT TYPE="
BUTTON
" NAME="
close
" value="
/blog/关闭这个窗口
" onClick="
closeclk()
">
</FORM>
二、上面的代码也太静了,为何不来点动感呢?如果能给页面来个降落效果那该多好啊!
代码如下:
<script>
function drop(n) {
if(self.moveBy){
self.moveBy (0,-900);
for(i = n; i > 0; i--){
self.moveBy(0,3);
}
for(j = 8; j > 0; j--){
self.moveBy(0,j);
self.moveBy(j,0);
self.moveBy(0,-j);
self.moveBy(-j,0);
}
}
}
</script>
<body onLoad="
drop(300)
">
三、讨厌很多网站总是按照默认窗口打开,如果你能随心所欲控制打开的窗口那该多好。
代码如下:
<SCRIPT LANGUAGE="
JavaScript
">
<!-- Begin
function popupPage(l, t, w, h) {
var windowprops = "
location=no,scrollbars=no,menubars=no,toolbars=no,resizable=yes
" +
"
,left=
" + l + "
,top=
" + t + "
,width=
" + w + "
,height=
" + h;
var URL = "
http:
//www.80cn.com";
popup = window.open(URL,"MenuPopup
",windowprops);
}
// End -->
</script>
<table>
<tr>
<td>
<form name=popupform>
<pre>
打开页面的参数 <br>
离开左边的距离: <input type=text name=left size=2 maxlength=4> pixels
离开右边的距离: <input type=text name=top size=2 maxlength=4> pixels
窗口的宽度: <input type=text name=width size=2 maxlength=4> pixels
窗口的高度: <input type=text name=height size=2 maxlength=4> pixels
</pre>
<center>
<input type=button value="
打开这个窗口!
" onClick="
popupPage(
this
.form.left.value,
this
.form.top.value,
this
.form.width.value,
this
.form.height.value)">
</center>
</form>
</td>
</tr>
</table>你只要在相对应的对话框中输入一个数值即可,将要打开的页面的窗口控制得很好。
