43、javascript主页弹出窗口技巧
窗口中间弹出
< script >
window.open("http://www.cctv.com","","width=400,height=240,top="+(screen.availHeight-240)/2+",left="+(screen.availWidth-400)/2);
script >
============
< html >
< head >
< script language ="LiveScript" >
function WinOpen() {
msg=open("","DisplayWindow","toolbar=no,directories=no,menubar=no");
msg.document.write("哈 罗! ");
msg.document.write(" ");
}
script >
head >
< body >
< form >
< input type ="button" name ="Button1" value ="Push me" onclick ="WinOpen()" >
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('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 ="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。
44、页面的打开移动
把如下代码加入 < body > 区域中
< SCRIPT LANGUAGE ="javascript" >
// End -->
script >
45、显示个人客户端机器的日期和时间
< script language ="LiveScript" >
script >
46、自动的为你每次产生最後修改的日期了:
< html >
< body >
This is a simple HTML- page.
< br >
Last changes:
< script language ="LiveScript" >
script >
body >
html >
47、不能为空和邮件地址的约束:
< html >
< head >
< script language ="javascript" >
script >
head >
< body >
< form name ="first" >
Enter your name: < br >
< input type ="text" name ="text1" >
< input type ="button" name ="button1" value ="输 入 测 试" onClick ="test1(this.form)" >
< P >
Enter your e-mail address: < br >
< input type ="text" name ="text2" >
< input type ="button" name ="button2" value ="输 入 测 试" onClick ="test2(this.form)" >
body >
48、跑马灯
< html >
< head >
< script language ="javascript" >
script >
head >
< body onLoad ="scroll();return true;" >
这里可显示您的网页 !
body >
html >
49、在网页中用按钮来控制前页,后页和主页的显示。
< html >
< body >
< FORM NAME ="buttonbar" >
< INPUT TYPE ="button" VALUE ="Back" onClick ="history.back()" >
< INPUT TYPE ="button" VALUE ="JS- Home" onClick ="location='script.html'" >
< INPUT TYPE ="button" VALUE ="Next" onCLick ="history.forward()" >
FORM >
body >
html >
50、查看某网址的源代码
把如下代码加入 < body > 区域中
< SCRIPT >
function add()
{
var ress=document.forms[0].luxiaoqing.value
window.location="view-source:"+ress;
}
SCRIPT >
输入要查看源代码的URL地址:
< FORM >< input type ="text" name ="luxiaoqing" size =40 value ="http://" > FORM >
< FORM >< br >
< INPUT type ="button" value ="查看源代码" onClick =add() >
FORM >
51、title显示日期
把如下代码加入 < body > 区域中:
< script language ="javascript1.2" >
script >

script >
< input type ="button" onClick ="extractlinks()" value ="显示所有的连接" >
53、回车键换行
把如下代码加入 < body > 区域中
< script type ="text/javascript" >
function handleEnter (field, event) {
var keyCode = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;
if (keyCode == 13) {
var i;
for (i = 0; i < field.form.elements.length; i++)
if (field == field.form.elements)
break;
i = (i + 1) % field.form.elements.length;
field.form.elements.focus();
return false;
}
else
return true;
}
script >
< form >
< input type ="text" onkeypress ="return handleEnter(this, event)" >< br >
< input type ="text" onkeypress ="return handleEnter(this, event)" >< br >
< textarea > 回车换行
54、确认后提交
把如下代码加入 < body > 区域中
< SCRIPT LANGUAGE ="javascript" >
SCRIPT >
< form name ="lnman" method ="post" action ="" >
< p >
< input type ="text" name ="textfield" value ="确认后提交" >
p >
< p >
< input type ="button" name ="Submit" value ="提交" onclick ="msg();" >
p >
form >
55、改变表格的内容
把如下代码加入 < body > 区域中

41、email地址的分割
把如下代码加入 < body > 区域中
< a href ="mailto:[email protected]" > [email protected] a >
42、流动边框效果的表格
把如下代码加入 < body > 区域中
< SCRIPT >
l=Array(6,7,8,9,'a','b','b','c','d','e','f')
Nx=5;Ny=35
t="
"+x+"> | "||
"+(Nx-1)+"> | "+(Ny-2)+" rowspan="+(Nx)+"> | "+(Nx+Ny)+"> |
"+(Nx-x)+"> | "+(Ny+Nx+x-1)+"> | |
"+(x+Nx*2+Ny-1)+"> | "
var N=Nx*2+Ny*2
function f1(y){
for(i=0;i<N;i++){
c=(i+y)%20;if(c>10)c=20-c
document.all["a_mo"+(i)].bgColor="'#0000"+l[c]+l[c]+"'"}
y++
setTimeout('f1('+y+')','1')}

43、javascript主页弹出窗口技巧
窗口中间弹出
< script >
window.open("http://www.cctv.com","","width=400,height=240,top="+(screen.availHeight-240)/2+",left="+(screen.availWidth-400)/2);
script >
============
< html >
< head >
< script language ="LiveScript" >
function WinOpen() {
msg=open("","DisplayWindow","toolbar=no,directories=no,menubar=no");
msg.document.write("
msg.document.write("
酷 毙 了!
这 是javascript所 开 的 视 窗!
}
script >
head >
< body >
< form >
< input type ="button" name ="Button1" value ="Push me" onclick ="WinOpen()" >
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('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 ="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。
44、页面的打开移动
把如下代码加入 < body > 区域中
< SCRIPT LANGUAGE ="javascript" >
// End -->
script >
45、显示个人客户端机器的日期和时间
< script language ="LiveScript" >
script >
46、自动的为你每次产生最後修改的日期了:
< html >
< body >
This is a simple HTML- page.
< br >
Last changes:
< script language ="LiveScript" >
script >
body >
html >
47、不能为空和邮件地址的约束:
< html >
< head >
< script language ="javascript" >
script >
head >
< body >
< form name ="first" >
Enter your name: < br >
< input type ="text" name ="text1" >
< input type ="button" name ="button1" value ="输 入 测 试" onClick ="test1(this.form)" >
< P >
Enter your e-mail address: < br >
< input type ="text" name ="text2" >
< input type ="button" name ="button2" value ="输 入 测 试" onClick ="test2(this.form)" >
body >
48、跑马灯
< html >
< head >
< script language ="javascript" >
script >
head >
< body onLoad ="scroll();return true;" >
这里可显示您的网页 !
body >
html >
49、在网页中用按钮来控制前页,后页和主页的显示。
< html >
< body >
< FORM NAME ="buttonbar" >
< INPUT TYPE ="button" VALUE ="Back" onClick ="history.back()" >
< INPUT TYPE ="button" VALUE ="JS- Home" onClick ="location='script.html'" >
< INPUT TYPE ="button" VALUE ="Next" onCLick ="history.forward()" >
FORM >
body >
html >
50、查看某网址的源代码
把如下代码加入 < body > 区域中
< SCRIPT >
function add()
{
var ress=document.forms[0].luxiaoqing.value
window.location="view-source:"+ress;
}
SCRIPT >
输入要查看源代码的URL地址:
< FORM >< input type ="text" name ="luxiaoqing" size =40 value ="http://" > FORM >
< FORM >< br >
< INPUT type ="button" value ="查看源代码" onClick =add() >
FORM >
51、title显示日期
把如下代码加入 < body > 区域中:
< script language ="javascript1.2" >
script >
52、显示所有链接
把如下代码加入 < body > 区域中
< script language ="javascript1.2" >
script >
< input type ="button" onClick ="extractlinks()" value ="显示所有的连接" >
53、回车键换行
把如下代码加入 < body > 区域中
< script type ="text/javascript" >
function handleEnter (field, event) {
var keyCode = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;
if (keyCode == 13) {
var i;
for (i = 0; i < field.form.elements.length; i++)
if (field == field.form.elements)
break;
i = (i + 1) % field.form.elements.length;
field.form.elements.focus();
return false;
}
else
return true;
}
script >
< form >
< input type ="text" onkeypress ="return handleEnter(this, event)" >< br >
< input type ="text" onkeypress ="return handleEnter(this, event)" >< br >
< textarea > 回车换行
54、确认后提交
把如下代码加入 < body > 区域中
< SCRIPT LANGUAGE ="javascript" >
SCRIPT >
< form name ="lnman" method ="post" action ="" >
< p >
< input type ="text" name ="textfield" value ="确认后提交" >
p >
< p >
< input type ="button" name ="Submit" value ="提交" onclick ="msg();" >
p >
form >
55、改变表格的内容
把如下代码加入 < body > 区域中
< script language =javascript >
var arr=new Array()
arr[0]="一一一一一";
arr[1]="二二二二二";
arr[2]="三三三三三";
script >
< select onchange ="zz.cells[this.selectedIndex].innerHTML=arr[this.selectedIndex]" >
< option value =a > 改变第一格 option >
< option value =a > 改变第二格 option >
< option value =a > 改变第三格 option >
select >
< table id =zz border =1 >
< tr height =20 >
< td width =150 > 第一格 td >
< td width =150 > 第二格 td >
< td width =150 > 第三格 td >
tr >
table >
