实用JS大全

****************************************************************
（一）常用元素，对象，事件，技巧

事件源对象
event.srcElement.tagName
event.srcElement.type
捕获释放
event.srcElement.setCapture();
event.srcElement.releaseCapture();
事件按键
event.keyCode
event.shiftKey
event.altKey
event.ctrlKey
事件返回值
event.returnValue
鼠标位置
event.x
event.y
窗体活动元素
document.activeElement
绑定事件
document.captureEvents(Event.KEYDOWN);
访问窗体元素
document.all("txt").focus();
document.all("txt").select();
窗体命令
document.execCommand
窗体COOKIE
document.cookie
菜单事件
document.oncontextmenu
创建元素
document.createElement("SPAN");
根据鼠标获得元素：
document.elementFromPoint(event.x,event.y).tagName=="TD
document.elementFromPoint(event.x,event.y).appendChild(ms)
窗体图片
document.images[索引]
窗体事件绑定
document.onmousedown=scrollwindow;
元素
document.窗体.elements[索引]
对象绑定事件
document.all.xxx.detachEvent('onclick',a);
插件数目
navigator.plugins
取变量类型
typeof($js_libpath) == "undefined"
下拉框
下拉框.options[索引]
下拉框.options.length
查找对象
document.getElementsByName("r1");
document.getElementById(id);
定时
timer=setInterval('scrollwindow()',delay);
clearInterval(timer);
UNCODE编码
escape() ,unescape
父对象
obj.parentElement(dhtml)
obj.parentNode(dom)
交换表的行
TableID.moveRow(2,1)
替换CSS
document.all.csss.href = "a.css";
并排显示
display:inline
隐藏焦点
hidefocus=true
根据宽度换行
style="word-break:break-all"
自动刷新
<meta HTTP-EQUIV="refresh" C>
简单邮件
<a href="[email=aaa@bbb.com?subject=ccc&body=xxxyyy]mailto:aaa@bbb.com?subject=ccc&body=xxxyyy[/email]">
快速转到位置
obj.scrollIntoView(true)
锚
<a name="first">
<a href="#first">anchors</a>
网页传递参数
location.search();
可编辑
obj.contenteditable=true
执行菜单命令
obj.execCommand
双字节字符
/[^/x00-/xff]/
汉字
/[/u4e00-/u9fa5]/
让英文字符串超出表格宽度自动换行
word-wrap: break-word; word-break: break-all;
透明背景
<IFRAME src="1.htm" width=300 height=180 allowtransparency></iframe>
获得style内容
obj.style.cssText
HTML标签
document.documentElement.innerHTML
第一个style标签
document.styleSheets[0]
style标签里的第一个样式
document.styleSheets[0].rules[0]
防止点击空链接时，页面往往重置到页首端。
<a href="javascript:function()">word</a>
上一网页源
asp:
request.servervariables("HTTP_REFERER")
javascript:
document.referrer
释放内存
CollectGarbage();
禁止右键
document.oncontextmenu = function() { return false;}
禁止保存
<noscript><iframe src="*.htm"></iframe></noscript>
禁止选取<body Shortcut Icon" href="favicon.ico">
favicon.ico 名字最好不变16*16的16色,放虚拟目录根目录下
收藏栏图标
<link rel="Bookmark" href="favicon.ico">
查看源码
<input type=button value=查看网页源代码 >
关闭输入法
<input style="ime-mode:disabled">
自动全选
<input type=text name=text1 value="123" >
ENTER键可以让光标移到下一个输入框
<input >
文本框的默认值
<input type=text value="123" >
title换行
obj.title = "123 sdfs "
获得时间所代表的微秒
var n1 = new Date("2004-10-10".replace(/-/g, "//")).getTime()
窗口是否关闭
win.closed
checkbox扁平
<input type=checkbox style="position: absolute; clip:rect(5px 15px 15px 5px)"><br>
获取选中内容
document.selection.createRange().duplicate().text
自动完成功能
<input type=text autocomplete=on>打开该功能
<input type=text autocomplete=off>关闭该功能
窗口最大化
<body >
无关闭按钮IE window.open("aa.htm", "meizz", "fullscreen=7");
统一编码/解码 alert(decodeURIComponent(encodeURIComponent("http://你好.com?as= hehe")))
encodeURIComponent对":"、"/"、";" 和 "?"也编码

></a>' target=_blank);
theFloaters.play();

3.[允许关闭]
与前面两个代码不同的是，广告图下方增加了一个图片按纽，允许访客点击关闭广告图片，下面文本框中就是实现效果所需代码：

var delta=0.015;
var collection;
var closeB=false;
function floaters() {
this.items = [];
this.addItem = function(id,x,y,content)
{
document.write('<DIV id='+id+' style="Z-INDEX: 10; 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()',30);
}
}
function play()
{
if(screen.width<=800 || closeB)
{
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 = '';
}
}
function closeBanner()
{
closeB=true;
return;
}

var theFloaters = new floaters();
//
theFloaters.addItem('followDiv1','document.body.clientWidth-100',0,'<a  href=http://www.dfeng.net target=_blank><img src=ad/doublead/right.gif width=100 height=554 border=0></a><br><br><img src=ad/doublead/close.gif >');
theFloaters.addItem('followDiv2',0,0,'<a  href=http://www.dfeng.net target=_blank><img src=ad/doublead/ad_ad.gif width=100 height=400 border=0 ></a><br><br><img src=ad/doublead/close.gif >');
theFloaters.play();

把上面的代码分别另存为两个JS文件，然后在想实现此效果的页面用

<script type="text/javascript" language="javascript1.2" src="*.js"></SCRIPT>

调用即可，*代表你另存的文件名！注意修改广告图片地址和连接地址！
