javascript小技巧[转]
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" 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
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 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网页正文全文宽："+ document.body.scrollWidth;
s += "\r\n网页正文全文高："+ document.body.scrollHeight;
s += "\r\n网页被卷去的高："+ document.body.scrollTop;
s += "\r\n网页被卷去的左："+ document.body.scrollLeft;
s += "\r\n网页正文部分上："+ window.screenTop;
s += "\r\n网页正文部分左："+ window.screenLeft;
s += "\r\n屏幕分辨率的高："+ window.screen.height;
s += "\r\n屏幕分辨率的宽："+ window.screen.width;
s += "\r\n屏幕可用工作区高度："+ window.screen.availHeight;
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

JavaScript就这么回事
有些时候你精通一门语言，但是会发现你其实整天在和其它语言打交道， 也许你以为这些微不足道，不至于影响你的开发进度，但恰恰是这些你不重视的东西会浪费你很多时间，我一直以为我早在几年前就已经精通JavaScript 了，直到目前，我才越来越觉得JavaScript远比我想象的复杂和强大，我开始崇拜它，就像崇拜所有OOP语言一样～
趁着节日的空隙，把有关JavaScript的方法和技巧整理下，让每个在为JavaScript而烦恼的人明白，JavaScript就这么回事！并希望JavaScript还可以成为你的朋友，让你豁然开朗，在项目中更好的应用～
适合阅读范围：对JavaScript一无所知～离精通只差一步之遥的人

12: </form>
[color=Purple]50 验证Select项[/color]
1: function checkList(selection) {
2: if (selection.length == 0) {
3: window.alert(“You must make a selection from the list.”);
4: return false;
5: }
6: return true;
7: }
51 动态改变表单的action
1: <form name=”myForm” action=”login.html”>
2: Username: <input type=”text” name=”username”><br>
3: Password: <input type=”password” name=”password”><br>
4: <input type=”button” value=”Login” onClick=”this.form.submit();”>
5: <input type=”button” value=”Register” onClick=”this.form.action = ‘register.html’; this.form.submit();”>
6: <input type=”button” value=”Retrieve Password” onClick=”this.form.action = ‘password.html’; this.form.submit();”>
7: </form>
52 使用图像按钮
1: <form name=”myForm” action=”login.html”>
2: Username: <input type=”text” name=”username”><br>
3: Password: <input type=”password”name=”password”><br>
4: <input type=”image” src="/”login.gif"” value=”Login”>
5: </form>

53 表单数据的加密
1: <SCRIPT LANGUAGE='JavaScript'>
2: <!--
3: function encrypt(item) {
4: var newItem = '';
5: for (i=0; i < item.length; i++) {
6: newItem += item.charCodeAt(i) + '.';
7: }
8: return newItem;
9: }
10: function encryptForm(myForm) {
11: for (i=0; i < myForm.elements.length; i++) {
12: myForm.elements[i].value = encrypt(myForm.elements[i].value);
13: }
14: }
15:
16: //-->
17: </SCRIPT>
18: <form name='myForm' onSubmit='encryptForm(this); window.alert(this.myField.value);'>
19: Enter Some Text: <input type=text name=myField><input type=submit>
20: </form>
JavaScript就这么回事5：窗口和框架
54 改变浏览器状态栏文字提示
1: <script language=”JavaScript”>
2: window.status = “A new status message”;
3: </script>
55 弹出确认提示框
1: <script language=”JavaScript”>
2: var userChoice = window.confirm(“Click OK or Cancel”);
3: if (userChoice) {
4: document.write(“You chose OK”);
5: } else {
6: document.write(“You chose Cancel”);
7: }
8: </script>
56 提示输入
1: <script language=”JavaScript”>
2: var userName = window.prompt(“Please Enter Your Name”,”Enter Your Name Here”);
3: document.write(“Your Name is “ + userName);
4: </script>
57 打开一个新窗口
1: //打开一个名称为myNewWindow的浏览器新窗口
2: <script language=”JavaScript”>
3: window.open(“http://www.liu21st.com/”,”myNewWindow”);
4: </script>
58 设置新窗口的大小
1: <script language=”JavaScript”>
2: window.open(“http://www.liu21st.com/”,”myNewWindow”,'height=300,width=300');
3: </script>
59 设置新窗口的位置
1: <script language=”JavaScript”>
2: window.open(“http://www.liu21st.com/”,”myNewWindow”,'height=300,width=300,left=200,screenX=200,top=100,screenY=100');
3: </script>
60 是否显示工具栏和滚动栏
1: <script language=”JavaScript”>
2: window.open(“http: ?????????????
61 是否可以缩放新窗口的大小
1: <script language=”JavaScript”>
2: window.open('http://www.liu21st.com/' , 'myNewWindow', 'resizable=yes' );</script>
62 加载一个新的文档到当前窗口
1: <a href='#' onClick='document.location = '125a.html';' >Open New Document</a>
63 设置页面的滚动位置
1: <script language=”JavaScript”>
2: if (document.all) { //如果是IE浏览器则使用scrollTop属性
3: document.body.scrollTop = 200;
4: } else { //如果是NetScape浏览器则使用pageYOffset属性
5: window.pageYOffset = 200;
6: }</script>
64 在IE中打开全屏窗口
1: <a href='#' onClick=”window.open('http://www.juxta.com/','newWindow','fullScreen=yes');”>Open a full-screen window</a>
65 新窗口和父窗口的操作
1: <script language=”JavaScript”>
2: //定义新窗口
3: var newWindow = window.open(“128a.html”,”newWindow”);
4: newWindow.close(); //在父窗口中关闭打开的新窗口
5: </script>
6: 在新窗口中关闭父窗口
7: window.opener.close()
66 往新窗口中写内容
1: <script language=”JavaScript”>
2: var newWindow = window.open(“”,”newWindow”);
3: newWindow.document.open();
4: newWindow.document.write(“This is a new window”);
5: newWIndow.document.close();
6: </script>
67 加载页面到框架页面
1: <frameset cols=”50%,*”>
2: <frame name=”frame1” src="/”135a.html"”>
3: <frame name=”frame2” src="/”about:blank"”>
4: </frameset>
5: 在frame1中加载frame2中的页面
6: parent.frame2.document.location = “135b.html”;
68 在框架页面之间共享脚本
如果在frame1中html文件中有个脚本
1: function doAlert() {
2: window.alert(“Frame 1 is loaded”);
3: }
那么在frame2中可以如此调用该方法
1: <body onLoad=”parent.frame1.doAlert();”>
2: This is frame 2.
3: </body>
69 数据公用
可以在框架页面定义数据项，使得该数据可以被多个框架中的页面公用
1: <script language=”JavaScript”>
2: var persistentVariable = “This is a persistent value”;
3: </script>
4: <frameset cols=”50%,*”>
5: <frame name=”frame1” src="/”138a.html"”>
6: <frame name=”frame2” src="/”138b.html"”>
7: </frameset>
这样在frame1和frame2中都可以使用变量persistentVariable
70 框架代码库
根据以上的一些思路，我们可以使用一个隐藏的框架页面来作为整个框架集的代码库
1: <frameset cols=”0,50%,*”>
2: <frame name=”codeFrame” src="/”140code.html"”>
3: <frame name=”frame1” src="/”140a.html"”>
4: <frame name=”frame2” src="/”140b.html"”>
5: </frameset>

//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,''))"

JavaScript就这么回事
有些时候你精通一门语言，但是会发现你其实整天在和其它语言打交道， 也许你以为这些微不足道，不至于影响你的开发进度，但恰恰是这些你不重视的东西会浪费你很多时间，我一直以为我早在几年前就已经精通JavaScript 了，直到目前，我才越来越觉得JavaScript远比我想象的复杂和强大，我开始崇拜它，就像崇拜所有OOP语言一样～
趁着节日的空隙，把有关JavaScript的方法和技巧整理下，让每个在为JavaScript而烦恼的人明白，JavaScript就这么回事！并希望JavaScript还可以成为你的朋友，让你豁然开朗，在项目中更好的应用～

6: newItem += item.charCodeAt(i) + '.';
7: }
8: return newItem;
9: }
10: function encryptForm(myForm) {
11: for (i=0; i < myForm.elements.length; i++) {
12: myForm.elements[i].value = encrypt(myForm.elements[i].value);
13: }
14: }
15:
16: //-->
17: </SCRIPT>
18: <form name='myForm' onSubmit='encryptForm(this); window.alert(this.myField.value);'>
19: Enter Some Text: <input type=text name=myField><input type=submit>
20: </form>
JavaScript就这么回事5：窗口和框架
54 改变浏览器状态栏文字提示
1: <script language=”JavaScript”>
2: window.status = “A new status message”;
3: </script>
55 弹出确认提示框
1: <script language=”JavaScript”>
2: var userChoice = window.confirm(“Click OK or Cancel”);
3: if (userChoice) {
4: document.write(“You chose OK”);
5: } else {
6: document.write(“You chose Cancel”);
7: }
8: </script>
56 提示输入
1: <script language=”JavaScript”>
2: var userName = window.prompt(“Please Enter Your Name”,”Enter Your Name Here”);
3: document.write(“Your Name is “ + userName);
4: </script>
57 打开一个新窗口
1: //打开一个名称为myNewWindow的浏览器新窗口
2: <script language=”JavaScript”>
3: window.open(“http://www.liu21st.com/”,”myNewWindow”);
4: </script>
58 设置新窗口的大小
1: <script language=”JavaScript”>
2: window.open(“http://www.liu21st.com/”,”myNewWindow”,'height=300,width=300');
3: </script>
59 设置新窗口的位置
1: <script language=”JavaScript”>
2: window.open(“http://www.liu21st.com/”,”myNewWindow”,'height=300,width=300,left=200,screenX=200,top=100,screenY=100');
3: </script>
60 是否显示工具栏和滚动栏
1: <script language=”JavaScript”>
2: window.open(“http: ?????????????
61 是否可以缩放新窗口的大小
1: <script language=”JavaScript”>
2: window.open('http://www.liu21st.com/' , 'myNewWindow', 'resizable=yes' );</script>
62 加载一个新的文档到当前窗口
1: <a href='#' onClick='document.location = '125a.html';' >Open New Document</a>
63 设置页面的滚动位置
1: <script language=”JavaScript”>
2: if (document.all) { //如果是IE浏览器则使用scrollTop属性
3: document.body.scrollTop = 200;
4: } else { //如果是NetScape浏览器则使用pageYOffset属性
5: window.pageYOffset = 200;
6: }</script>
64 在IE中打开全屏窗口
1: <a href='#' onClick=”window.open('http://www.juxta.com/','newWindow','fullScreen=yes');”>Open a full-screen window</a>
65 新窗口和父窗口的操作
1: <script language=”JavaScript”>
2: //定义新窗口
3: var newWindow = window.open(“128a.html”,”newWindow”);
4: newWindow.close(); //在父窗口中关闭打开的新窗口
5: </script>
6: 在新窗口中关闭父窗口
7: window.opener.close()
66 往新窗口中写内容
1: <script language=”JavaScript”>
2: var newWindow = window.open(“”,”newWindow”);
3: newWindow.document.open();
4: newWindow.document.write(“This is a new window”);
5: newWIndow.document.close();
6: </script>
67 加载页面到框架页面
1: <frameset cols=”50%,*”>
2: <frame name=”frame1” src="/”135a.html"”>
3: <frame name=”frame2” src="/”about:blank"”>
4: </frameset>
5: 在frame1中加载frame2中的页面
6: parent.frame2.document.location = “135b.html”;
68 在框架页面之间共享脚本
如果在frame1中html文件中有个脚本
1: function doAlert() {
2: window.alert(“Frame 1 is loaded”);
3: }
那么在frame2中可以如此调用该方法
1: <body onLoad=”parent.frame1.doAlert();”>
2: This is frame 2.
3: </body>
69 数据公用
可以在框架页面定义数据项，使得该数据可以被多个框架中的页面公用
1: <script language=”JavaScript”>
2: var persistentVariable = “This is a persistent value”;
3: </script>
4: <frameset cols=”50%,*”>
5: <frame name=”frame1” src="/”138a.html"”>
6: <frame name=”frame2” src="/”138b.html"”>
7: </frameset>
这样在frame1和frame2中都可以使用变量persistentVariable
70 框架代码库
根据以上的一些思路，我们可以使用一个隐藏的框架页面来作为整个框架集的代码库
1: <frameset cols=”0,50%,*”>
2: <frame name=”codeFrame” src="/”140code.html"”>
3: <frame name=”frame1” src="/”140a.html"”>
4: <frame name=”frame2” src="/”140b.html"”>
5: </frameset>
