javascript小技巧使用集合
取得网络上的打印机 function getnetprinter() { var obj=new ActiveXObject("WScript.Network"); var netprinter=obj.EnumPrinterConnections(); for(i=0;i<netprinter.Count();i+=2) { document.writeln(netprinter.Item(i)+"="+netprinter.Item(i+1)); } } 取得磁盘信息 传入参数如：getdiskinfo('c') function getdiskinfo(para) { var fs=new ActiveXObject("scripting.filesystemobject"); d=fs.GetDrive(para); s="卷标:" + d.VolumnName; s+="------" + "剩余空间:" + d.FreeSpace/1024/1024 + "M"; s+="------" + "磁盘序列号:" + d.serialnumber; alert(s) } 取得系统目录 function getprocessnum() { var pnsys=new ActiveXObject("WScript.shell"); pn=pnsys.Environment("PROCESS"); alert(pn("WINDIR")); } 启动计算器 function runcalc() { var calc=new ActiveXObject("WScript.shell"); calc.Run("calc"); } 读取注册表中的值 function readreg() { var myreadreg=new ActiveXObject("WScript.shell"); try{ alert(myreadreg.RegRead("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\NeroCheck")); } catch(e) { alert("读取的值不存在！"); } } 写注册表 function writereg() { var mywritereg=new ActiveXObject("WScript.shell"); try{ mywritereg.RegWrite("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\MyTest","c:\\mytest.exe"); alert("写入成功！"); } catch(e) { alert("写入路径不正确！"); } } 删除注册表 function delreg() { var mydelreg=new ActiveXObject("WScript.shell"); if(confirm("是否真的删除？")) { try{ mydelreg.RegDelete("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\\MyTest"); alert("删除成功！"); } catch(e) { alert("删除路径不正确"); } } } 取得计算机名域名用户名 function netinfo() { var mynetinfo=new ActiveXObject("WScript.network"); alert("计算机名:"+mynetinfo.ComputerName+"域名:"+mynetinfo.UserDomain+"用户名:"+mynetinfo.UserName); } 返回系统中特殊目录的路径 (Fonts,AllUsersDesktop,Desktop,MyDocuments,Recent.....) function getspecialfolder() { var mygetfolder=new ActiveXObject("WScript.shell"); if(mygetfolder.SpecialFolders("Fonts")!=null) { alert(mygetfolder.SpecialFolders("Fonts")); } } 取得文件信息 调用方式如：getfileinfo('E:\\MyPlace\\TEST\\myjs.htm') function getfileinfo(para) { var myfile=new ActiveXObject("scripting.filesystemobject"); var fi=myfile.GetFile(para); alert("文件类型:"+fi.type+"文件大小:"+fi.size/1024/1024+"M"+"最后一次访问时间:"+fi.DateLastAccessed); } 取得客户端的信息 function clientInfo() { strClientInfo="availHeight= "+window.screen.availHeight+"\n"+ "availWidth= "+window.screen.availWidth+"\n"+ "bufferDepth= "+window.screen.bufferDepth+"\n"+ "colorDepth= "+window.screen.colorDepth+"\n"+ "colorEnable= "+window.navigator.cookieEnabled+"\n"+ "cpuClass= "+window.navigator.cpuClass+"\n"+ "height= "+window.screen.height+"\n"+ "javaEnable= "+window.navigator.javaEnabled()+"\n"+ "platform= "+window.navigator.platform+"\n"+ "systemLanguage= "+window.navigator.systemLanguage+"\n"+ "userLanguage= "+window.navigator.userLanguage+"\n"+ "width= "+window.screen.width; alert(strClientInfo); } Dilog Helper对象的使用 function changeColor()//Dilog Helper对象的使用之调用系统调色板 { var sColor=dlgHelper.choosecolordlg(); sColor=sColor.toString(16); if (sColor.length < 6) { var sTempString = "000000".substring(0,6-sColor.length); sColor = sTempString.concat(sColor); } alert(sColor); mybody.style.backgroundColor=sColor; } function getFonts()//Dilog Helper对象的使用之取得系统支持的字体 { var strFonts=""; for(var i=1;i<dlgHelper.fonts.count;i++) { strFonts=strFonts+dlgHelper.fonts(i)+"|"; } alert(strFonts); } function getBlockFormat()//Dilog Helper对象的使用之取得系统中块的格式信息（如：标题1、标题2....） { var strBlockFormat=""; for(var i=1;i<dlgHelper.BlockFormats.count;i++) { strBlockFormat=strBlockFormat+dlgHelper.BlockFormats(i)+"|"; } alert(strBlockFormat); } 给选中的文本创建链接 function createTxtLink() { var sText=document.selection.createRange(); if(sText.text!="") { document.execCommand("CreateLink"); if(sText.parentElement().tagName=="A") { sText.parentElement().innerText=sText.parentElement().href; document.execCommand("ForeColor",false,"#ffff00"); } } } 以下为取得BlockFormats,填充Select（id为myselect）并根据选择不同的BlockFormat改变样式 //函数fillselect()和changeformat() //对execCommand的一点说明：Executes a command over the given selection or text range function fillselect() { var item=document.createElement("OPTION") item.text="请选择"; item.value=""; myselect.add(item); for(var i=1;i<dlgHelper.BlockFormats.count;i++) { item=document.createElement("OPTION"); item.text=dlgHelper.BlockFormats(i); item.value=dlgHelper.BlockFormats(i); myselect.add(item); } } function changeformat() { var sSelect=myselect.options[myselect.selectedIndex].value; document.execCommand("FormatBlock",false,sSelect); } 取得驱动器类型，调用如：ShowDriveType('c:') function ShowDriveType(drvpath) { fs=new ActiveXObject("scripting.filesystemobject"); disk=fs.GetDrive(drvpath); var whichtype=""; switch(disk.DriveType) { case 0: whichtype="Unknown" break case 1: whichtype="Removable" break case 2: whichtype="Fixed" break case 3: whichtype="Network" break case 4: whichtype="CD-ROM" break case 5: whichtype="RAM Disk" } alert(whichtype); 显示磁盘的SerialNumber try{ alert(disk.SerialNumber); } catch(e){ alert(e.message); } alert(disk.VolumeName);//取得卷标 } </script> －－－－－－－－－－－－－－－－－－－－－－－－－ <OBJECT id=dlgHelper CLASSID="clsid:3050f819-98b5-11cf-bb82-00aa00bdce0b" width="0px" height="0px"></OBJECT> var mywritereg=new ActiveXObject("WScript.shell");

//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,''))"
