javascript小技巧

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.οnmοusedοwn=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" CONTENT="8;URL=http://c98.yeah.net"> 简单邮件
<a href="mailto:aaa@bbb.com?subject=ccc&body=xxxyyy"> 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 οncοntextmenu="return false" οndragstart="return false" onselectstart ="return false" οnselect="document.selection.empty()" οncοpy="document.selection.empty()" onbeforecopy="return false"οnmοuseup="document.selection.empty()> 禁止粘贴

<link rel="Shortcut Icon" href="favicon.ico">

<input type=button value=查看网页源代码 οnclick="window.location = 'view-source:'+ 'http://www.csdn.net/'"> 关闭输入法
<input style="ime-mode:disabled"> 自动全选
<input type=text name=text1 value="123" οnfοcus="this.select()"> ENTER键可以让光标移到下一个输入框
<input οnkeydοwn="if(event.keyCode==13)event.keyCode=9"> 文本框的默认值
<input type=text value="123" οnfοcus="alert(this.defaultValue)"> 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

//特殊用途

//不缓存

//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：οnkeyup=
"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： οnkeyup=
"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：οnkeyup=
"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：οnkeyup=
"value=value.replace(/[\W]/g,'') "onbeforepaste=
"clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"

//消除图像工具栏

//无提示关闭

//取得控件得绝对位置(1)

//获得控件的绝对位置(2)

oRect = obj.getBoundingClientRect();

oRect.left

oRect.

//最小化,最大化,关闭

//光标停在文字最后

//页面进入和退出的特效

进入页面<meta http-equiv=
"Page-Enter" content=
"revealTrans(duration=x, transition=y)">

推出页面<meta http-equiv=
"Page-Exit" content=
"revealTrans(duration=x, transition=y)">

这个是页面被载入和调出时的一些特效。duration表示特效的持续时间，以秒为单位。transition表示使

用哪种特效，取值为1-23:

　　0 矩形缩小

　　1 矩形扩大

　　2 圆形缩小

　　3 圆形扩大

　　4 下到上刷新

　　5 上到下刷新

　　6 左到右刷新
