转 JAVASCRIPT 小技巧

转 JAVASCRIPT 小技巧
- 源自：cnblog DooIT : http://ttyp.cnblogs.com

  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)

- 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

- 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 oncontextmenu="return false" ondragstart="return false" onselectstart ="return false" onselect="document.selection.empty()" oncopy="document.selection.empty()" onbeforecopy="return false"onmouseup="document.selection.empty()>
- 禁止粘贴
  <input type=text onpaste="return false">
- 地址栏图标
  <link rel="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 onclick="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" onfocus="this.select()">
- ENTER键可以让光标移到下一个输入框
  <input onkeydown="if(event.keyCode==13)event.keyCode=9">
- 文本框的默认值
  <input type=text value="123" onfocus="alert(this.defaultValue)">
- title换行
  obj.title = "123&#13sdfs&#32"
- 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 onload="window.resizeTo(window.screen.width - 4,window.screen.height-50);window.moveTo(-4,-4)">
- 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
- 表格行指示
  <tr onmouseover="this.bgColor='#f0f0f0'" onmouseout="this.bgColor='#ffffff'">
  
  //各种尺寸
  
  s  +=  "/r/n网页可见区域宽："+  document.body.clientWidth;
  s  +=  "/r/n网页可见区域高："+  document.body.clientHeight;
  s  +=  "/r/n网页可见区域高："+  document.body.offsetWeight  +"  (包括边线的宽)";
  s  +=  "/r/n网页可见区域高："+  document.body.offsetHeight  +"  (包括边线的宽)";

  s  +=  "/r/n屏幕可用工作区宽度："+  window.screen.availWidth;
//过滤数字

//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：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,''))"

//消除图像工具栏

//无提示关闭

       str += '<param name="Command" value="Close"></object>';
       document.body.insertAdjacentHTML("beforeEnd", str);
       document.all.noTipClose.Click();
