高级应用(一)
页面跳转:
window.location.href('地址')
window.open('地址', '_self')
打开新窗口:
window.open('地址', '_blank')
只显示地址栏:window.open('地址', 'title', 'location=1, height=200, width=500')
只显示状态栏:window.open('地址', 'title', 'status=1')
只显示工具栏:window.open('地址', 'title', 'toolbar=1')
只显示菜单栏:window.open('地址', 'title', 'menubar=1')
一个不少:window.open('地址', 'title)
光棍但可以调整大小:window.open('地址', 'title', 'resizable=1')
去掉所有空格: Object.replace(/^\s+|\s+$/g, "")
弹出确认对话框:
comfirm('文本')"
<script>if(confirm('文本')){//确定}else{//取消}
回车转换Tab键:if(window.event.keyCode==13){event.keyCode=9}
重新加载页面: window.location.reload()
子页面中调父页面中的方法:window.opener.function()
子页面中访问父页面中名为name的控件值:window.opener.name.value
子页面中访问父页面中表单中名为name的控件值:window.opener.formName.nam.value
得到控件的绝对位置:
function getIE() {
var t = e.offsetTop;
var l = e.offsetLeft;
while (e = e.offsetParent) {
t += e.offsetTop;
l += e.offsetLeft;
}
alert("top=" + t + " and left=" + l);
}
光标停在文本框文字的最后:
function toEnd() {
var e = event.srcElement;
var r = e.createTextRange();
r.moveStart("character", e.value.length);
r.collapse(true);
r.select();
}
<input type="text" value="end" >
屏蔽功能键(Shift, Alt, Ctrl)
function testKey() {
if (event.shiftKey) { // altKey; ctrlKey
alert("Shift");
}
}
不要滚动条: <body scroll="no">
让竖条没有: <body style="overflow:scroll; overflow-y: hidden">
让横条没有: <body style="overflow:scroll; overflow-x: hidden">
去掉图片链接点击后图片周围的虚线: <a href="#" ><img src="test.jpg"></a>
在子窗体中刷新父窗体: window.opener.location.reload()
得到窗体大小:
document.body.clientWidth;
document.body.clientHeight;
TEXTAREA自适应文字行数:<textarea rows="1" cols="17" onpropertychange="this.style.posHeight=this.scrollHeight></textarea>
屏蔽脚本错误:
function killErrors() {
return true;
}
window.onerror=killErrors();
判断是否是字符:
if (/[^/x00-/xff]/g.test(str)) {
alert("有汉字");
} else {
alert("全是字符");
}

//正则匹配
匹配中文字符的正则表达式: [\u4e00-\u9fa5]
匹配双字节字符(包括汉字在内):[^\x00-\xff]
匹配空行的正则表达式:\n[\s| ]*\r
匹配HTML标记的正则表达式:/<(.*)>.*<\/\1>|<(.*) \/>/
匹配首尾空格的正则表达式:(^\s*)|(\s*$)(像vbscript那样的trim函数)
匹配Email地址的正则表达式:\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*
匹配网址URL的正则表达式:http://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?
以下是例子:
利用正则表达式限制网页表单里的文本框输入内容:
用正则表达式限制只能输入中文:onkeyup="value=value.replace(/[^\u4E00-\u9FA5]/g,'')" onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\u4E00-\u9FA5]/g,''))"
1.用正则表达式限制只能输入全角字符: onkeyup="value=value.replace(/[^\uFF00-\uFFFF]/g,'')" onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\uFF00-\uFFFF]/g,''))"
2.用正则表达式限制只能输入数字:onkeyup="value=value.replace(/[^\d]/g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
3.用正则表达式限制只能输入数字和英文:onkeyup="value=value.replace(/[\W]/g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"

{
openwin()
Set()
}
}
setTimeout("loadpopup()",5);
</script>
【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">
<!--
window.open ('page.html', 'newwindow', 'height=100, width=400, top=0,left=0, toolbar=no, menubar=no, scrollbars=no, resizable=no,location=no, status=no')
//写成一行
-->
</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">
<!--
function openwin() { window.open ("page.html", "newwindow", "height=100, width=400, toolbar=
no, menubar=no, scrollbars=no, resizable=no, location=no, status=no"
//写成一行
}
//-->
</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=""#"" _fcksavedurl=""#"" _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">
<!--
function openwin()
{ window.open ("page.html", "newwindow", "height=100, width=100, top=0,left=0,toolbar=no, menubar=no, scrollbars=no, resizable=no, location=no, status=no"
//写成一行
window.open ("page2.html", "newwindow2", "height=100, width=100, top=100, left=100,toolbar=no, menubar=no, scrollbars=no, resizable=no, location=no, status=no"
//写成一行
}
//-->
</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">
<!--
function openwin()
{window.open("page.html","","width=200,height=200"
}
//-->
</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!

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!
