this.replace([^/x00-/xff]/g,"aa").length;}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*$)应用：javascript中没有像vbscript那样的trim函数，我们就可以利用这个表达式来实现，如下：String.prototype.trim = function(){return this.replace(/(^/s*)|(/s*$)/g, "");}利用正则表达式分解和转换IP地址：下面是利用正则表达式匹配IP地址，并将IP地址转换成对应数值的Javascript程序：function IP2V(ip){re=/(/d+)/.(/d+)/.(/d+)/.(/d+)/g //匹配IP地址的正则表达式if(re.test(ip)){return RegExp.$1*Math.pow(255,3))+RegExp.$2*Math.pow(255,2))+RegExp.$3*255+RegExp.$4*1}else{throw new Error("Not a valid IP address!")}}不过上面的程序如果不用正则表达式，而直接用split函数来分解可能更简单，程序如下：var ip="10.100.20.168"ip=ip.split(".")alert("IP值是："+(ip[0]*255*255*255+ip[1]*255*255+ip[2]*255+ip[3]*1))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- ./?%&=]*)?//利用正则表达式去除字串中重复的字符的算法程序：var s="abacabefgeeii"var s1=s.replace(/(.).*/1/g,"$1")var re=new RegExp("["+s1+"]","g")var s2=s.replace(re,"")alert(s1+s2) //结果为：abcefgi思路是使用后向引用取出包括重复的字符，再以重复的字符建立第二个表达式，取到不重复的字符，两者串连。这个方法对于字符顺序有要求的字符串可能不适用。//得用正则表达式从URL地址中提取文件名的javascript程序，如下结果为page1s="http://www.9499.net/page1.htm"s=s.replace(/(.*//){0,}([^/.]+).*/ig,"$2")alert(s)/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,''))"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,''))"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,''))"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,''))"171.设置和使用cookie<HTML><BODY>设置与读取cookies...<BR>写入cookie的值<input

输出语句2.JS中的注释为//3.传统的HTML文档顺序是:document->html->(head,body)4.一个浏览器窗口中的DOM顺序是:window->(navigator,screen,history,location,document)5.得到表单中元素的名称和值:document.getElementByIdx_x("表单中元素的ID号").name(或value)6.一个小写转大写的JS: document.getElementByIdx_x("output").value = document.getElementByIdx_x("input").value.toUpperCase();7.JS中的值类型:String,Number,Boolean,Null,Object,Function8.JS中的字符型转换成数值型:parseInt(),parseFloat()9.JS中的数字转换成字符型:(""+变量)10.JS中的取字符串长度是:(length)11.JS中的字符与字符相连接使用+号.12.JS中的比较操作符有:==等于,!=不等于,>,>=,<.<=13.JS中声明变量使用:var来进行声明14.JS中的判断语句结构:if(condition){}else{}15.JS中的循环结构:for([initial expression];[condition];[upadte expression]) {inside loop}16.循环中止的命令是:break17.JS中的函数定义:function functionName([parameter],...){statement[s]}18.当文件中出现多个form表单时.可以用document.forms[0],document.forms[1]来代替.19.窗口:打开窗口window.open(), 关闭一个窗口:window.close(), 窗口本身:self20.状态栏的设置:window.status="字符";21.弹出提示信息:window.alert("字符");22.弹出确认框:window.confirm();23.弹出输入提示框:window.prompt();24.指定当前显示链接的位置:window.location.href="URL"25.取出窗体中的所有表单的数量:document.forms.length26.关闭文档的输出流:document.close();27.字符串追加连接符:+=28.创建一个文档元素:document.createElement_x(),document.createTextNode()29.得到元素的方法:document.getElementByIdx_x()30.设置表单中所有文本型的成员的值为空:var form = window.document.forms[0]for (var i = 0; i<form.elements.length;i++){if (form.elements[i].type == "text"){form.elements[i].value = "";}}31.复选按钮在JS中判断是否选中:document.forms[0].checkThis.checked (checked属性代表为是否选中返回TRUE或FALSE)32.单选按钮组(单选按钮的名称必须相同):取单选按钮组的长度document.forms[0].groupName.length33.单选按钮组判断是否被选中也是用checked.34.下拉列表框的值:document.forms[0].selectName.options[n].value (n有时用下拉列表框名称加上.selectedIndex来确定被选中的值)35.字符串的定义:var myString = new String("This is lightsword");36.字符串转成大写:string.toUpperCase(); 字符串转成小写:string.toLowerCase();37.返回字符串2在字符串1中出现的位置:String1.indexOf("String2")!=-1则说明没找到.38.取字符串中指定位置的一个字符:StringA.charAt(9);39.取出字符串中指定起点和终点的子字符串:stringA.substring(2,6);40.数学函数:Math.PI(返回圆周率),Math.SQRT2(返回开方),Math.max(value1,value2)返回两个数中的最在值,Math.pow(value1,10)返回value1的十次方,Math.round(value1)四舍五入函数,Math.floor(Math.random()*(n+1))返回随机数41.定义日期型变量:var today = new Date();42.日期函数列表:dateObj.getTime()得到时间,dateObj.getYear()得到年份,dateObj.getFullYear()得到四位的年份,dateObj.getMonth()得到月份,dateObj.getDate()得到日,dateObj.getDay()得到日期几,dateObj.getHours()得到小时,dateObj.getMinutes()得到分,dateObj.getSeconds()得到秒,dateObj.setTime(value)设置时间,dateObj.setYear(val)设置年,dateObj.setMonth(val)设置月,dateObj.setDate(val)设置日,dateObj.setDay(val)设置星期几,dateObj.setHours设置小时,dateObj.setMinutes(val)设置分,dateObj.setSeconds(val)设置秒[注意:此日期时间从0开始计]43.FRAME的表示方式: [window.]frames[n].ObjFuncVarName,frames["frameName"].ObjFuncVarName,frameName.ObjFuncVarName44.parent代表父亲对象,top代表最顶端对象45.打开子窗口的父窗口为:opener46.表示当前所属的位置:this47.当在超链接中调用JS函数时用:(javascript :)来开头后面加函数名48.在老的浏览器中不执行此JS:<!-- //-->49.引用一个文件式的JS:<script type="text/javascript" src="aaa.js"></script>50.指定在不支持脚本的浏览器显示的HTML:<noscript></noscript>51.当超链和ONCLICK事件都有时,则老版本的浏览器转向a.html,否则转向b.html.例:<a href="a.html" onclick="location.href='b.html';return false">dfsadf</a>52.JS的内建对象有:Array,Boolean,Date,Error,EvalError,Function,Math,Number,Object,RangeError,ReferenceError,RegExp,String,SyntaxError,TypeError,URIError53.JS中的换行:/n54.窗口全屏大小:<script>function fullScreen(){ this.moveTo(0,0);this.outerWidth=screen.availWidth;this.outerHeight=screen.availHeight;}window.maximize=fullScreen;</script>55.JS中的all代表其下层的全部元素56.JS中的焦点顺序:document.getElementByIdx_x("表单元素").tabIndex = 157.innerHTML的值是表单元素的值:如<p id="para">"how are <em>you</em>"</p>,则innerHTML的值就是:how are <em>you</em>58.innerTEXT的值和上面的一样,只不过不会把<em>这种标记显示出来.59.contentEditable可设置元素是否可被修改,isContentEditable返回是否可修改的状态.60.isDisabled判断是否为禁止状态.disabled设置禁止状态61.length取得长度,返回整型数值62.addBehavior()是一种JS调用的外部函数文件其扩展名为.htc63.window.focus()使当前的窗口在所有窗口之前.64.blur()指失去焦点.与FOCUS()相反.65.select()指元素为选中状态.66.防止用户对文本框中输入文本:onfocus="this.blur()"67.取出该元素在页面中出现的数量:document.all.tags("div(或其它HTML标记符)").length68.JS中分为两种窗体输出:模态和非模态.window.showModaldialog(),window.showModeless()69.状态栏文字的设置:window.status='文字',默认的状态栏文字设置:window.defaultStatus = '文字.';70.添加到收藏夹:external.AddFavorite("http://www.dannyg.com" ,"jaskdlf");71.JS中遇到脚本错误时不做任何操作:window.onerror = doNothing; 指定错误句柄的语法为:window.onerror = handleError;72.JS中指定当前打开窗口的父窗口:window.opener,支持opener.opener...的多重继续.73.JS中的self指的是当前的窗口74.JS中状态栏显示内容:window.status="内容"75.JS中的top指的是框架集中最顶层的框架76.JS中关闭当前的窗口:window.close();77.JS中提出是否确认的框:if(confirm("Are you sure?")){alert("ok");}else{alert("Not Ok");}78.JS中的窗口重定向:window.navigate("http://www.sina.com.cn");79.JS中的打印:window.print()80.JS中的提示输入框:window.prompt("message","defaultReply");81.JS中的窗口滚动条:window.scroll(x,y)82.JS中的窗口滚动到位置:window.scrollby83.JS中设置时间间隔:setInterval("expr",msecDelay)或setInterval(funcRef,msecDelay)或setTimeout84.JS中的模态显示在IE4+行,在NN中不行:showModalDialog("URL"[,arguments][,features]);85.JS中的退出之前使用的句柄:function verifyClose(){event.returnValue="we really like you and hope you will stay longer.";}} window.onbeforeunload=verifyClose;86.当窗体第一次调用时使用的文件句柄:onload()87.当窗体关闭时调用的文件句柄:onunload()88.window.location的属性: protocol(http:),hostname(www.example.com),port(80),host(www.example.com:80),pathname("/a/a.html"),hash("#giantGizmo",指跳转到相应的锚记),href(全部的信息)89.window.location.reload()刷新当前页面.90.window.history.back()返回上一页,window.history.forward()返回下一页,window.history.go(返回第几页,也可以使用访问过的URL)91.document.write()不换行的输出,document.writeln()换行输出92.document.body.noWrap=true;防止链接文字折行.93.变量名.charAt(第几位),取该变量的第几位的字符.94."abc".charCodeAt(第几个),返回第几个字符的ASCii码值.95.字符串连接:string.concat(string2),或用+=进行连接96.变量.indexOf("字符",起始位置),返回第一个出现的位置(从0开始计算)97.string.lastIndexOf(searchString[,startIndex])最后一次出现的位置.98.string.match(regExpression),判断字符是否匹配.99.string.replace(regExpression,replaceString)替换现有字符串.100.string.split(分隔符)返回一个数组存储值.101.string.substr(start[,length])取从第几位到指定长度的字符串.102.string.toLowerCase()使字符串全部变为小写.103.string.toUpperCase()使全部字符变为大写.104.parseInt(string[,radix(代表进制)])强制转换成整型.105.parseFloat(string[,radix])强制转换成浮点型.106.isNaN(变量):测试是否为数值型.107.定义常量的关键字:const,定义变量的关键字:var>>>---------我想分页！--这么长的文章，在这里来个分页多好啊！哈哈----------<<<程序代码//去左空格;function ltrim(s){return s.replace( /^/s*/, "");}程序代码//去右空格;function rtrim(s){return s.replace( //s*$/, "");}程序代码//左右空格;function trim(s){return rtrim(ltrim(s));}程序代码//替换function replace(s, t, u) {i = s.indexOf(t);r = "";if (i == -1) return s;r += s.substring(0,i) + u;if ( i + t.length < s.length)r += replace(s.substring(i + t.length, s.length), t, u);return r;}程序代码//检查非法字符//str 要检查的字符//badwords 非法字符&|<>=function checkbadwords(str, badwords) {if (typeof (str) != "string" || typeof (badwords) != "string") {return (false);}for (i=0;
