在b/s开发中经常用到的javaScript技术
<script> <BR>function checkAll(str) <BR>{ <BR>var a = document.getElementsByName(str); <BR>var n = a.length; <BR>for (var i=0; i<n; i++) <BR>a[i].checked = window.event.srcElement.checked; <BR>} <BR>function checkItem(str) <BR>{ <BR>var e = window.event.srcElement; <BR>var all = eval("document.hrong."+ str); <BR>if (e.checked) <BR>{ <BR>var a = document.getElementsByName(e.name); <BR>all.checked = true; <BR>for (var i=0; i<a.length; i++) <BR>{ <BR>if (!a[i].checked){ all.checked = false; break;} <BR>} <BR>} <BR>else all.checked = false; <BR>} <BR></script>
3.8 文件上传过程中判断文件类型
画图:
id=S <script> <BR>S.DrawingSurface.ArcDegrees(0,0,0,30,50,60); <BR>S.DrawingSurface.ArcRadians(30,0,0,30,50,60); <BR>S.DrawingSurface.Line(10,10,100,100); <BR></script>
写注册表：
<script> <BR>var WshShell = WScript.CreateObject("WScript.Shell"); <BR>WshShell.RegWrite ("HKCU\\Software\\ACME\\FortuneTeller\\", 1, "REG_BINARY"); <BR>WshShell.RegWrite ("HKCU\\Software\\ACME\\FortuneTeller\\MindReader", "Goocher!", "REG_SZ"); <BR>var bKey = WshShell.RegRead ("HKCU\\Software\\ACME\\FortuneTeller\\"); <BR>WScript.Echo (WshShell.RegRead ("HKCU\\Software\\ACME\\FortuneTeller\\MindReader")); <BR>WshShell.RegDelete ("HKCU\\Software\\ACME\\FortuneTeller\\MindReader"); <BR>WshShell.RegDelete ("HKCU\\Software\\ACME\\FortuneTeller\\"); <BR>WshShell.RegDelete ("HKCU\\Software\\ACME\\"); <BR></script>
TABLAE相关(客户端动态增加行列）
<script> <BR>function numberCells() { <BR>var count=0; <BR>for (i=0; i < document.all.mytable.rows.length; i++) { <BR>for (j=0; j < document.all.mytable.rows(i).cells.length; j++) { <BR>document.all.mytable.rows(i).cells(j).innerText = count; <BR>count++; <BR>} <BR>} <BR>} <BR></script>
１．身份证严格验证：
<script> <BR>var aCity={11:"北京",12:"天津",13:"河北",14:"山西",15:"内蒙古",21:"辽宁",22:"吉林",23:"黑龙江",31:"上海",32:"江苏",33:"浙江",34:"安徽",35:"福建",36:"江西",37:"山东",41:"河南",42:"湖北",43:"湖南",44:"广东",45:"广西",46:"海南",50:"重庆",51:"四川",52:"贵州",53:"云南",54:"西藏",61:"陕西",62:"甘肃",63:"青海",64:"宁夏",65:"新疆",71:"台湾",81:"香港",82:"澳门",91:"国外"} <br><br>function cidInfo(sId){ <BR>var iSum=0 <BR>var info="" <BR>if(!/^\d{17}(\d|x)$/i.test(sId))return false; <BR>sId=sId.replace(/x$/i,"a"); <BR>if(aCity[parseInt(sId.substr(0,2))]==null)return "Error:非法地区"; <BR>sBirthday=sId.substr(6,4)+"-"+Number(sId.substr(10,2))+"-"+Number(sId.substr(12,2)); <BR>var d=new Date(sBirthday.replace(/-/g,"/")) <BR>if(sBirthday!=(d.getFullYear()+"-"+ (d.getMonth()+1) + "-" + d.getDate()))return "Error:非法生日"; <BR>for(var i = 17;i>=0;i --) iSum += (Math.pow(2,i) % 11) * parseInt(sId.charAt(17 - i),11) <BR>if(iSum%11!=1)return "Error:非法证号"; <BR>return aCity[parseInt(sId.substr(0,2))]+","+sBirthday+","+(sId.substr(16,1)%2?"男":"女") <BR>} <br><br>document.write(cidInfo("380524198002300016"),"<br/>"); <BR>document.write(cidInfo("340524198002300019"),"<br/>") <BR>document.write(cidInfo("340524197711111111"),"<br/>") <BR>document.write(cidInfo("34052419800101001x"),"<br/>"); <BR></script>
２．验证ＩＰ地址
<script> <BR>function isip(s){ <BR>var check=function(v){try{return (v<=255 && v>=0)}catch(x){return false}}; <BR>var re=s.split(".") <BR>return (re.length==4)?(check(re[0]) && check(re[1]) && check(re[2]) && check(re[3])):false <BR>} <br><br>var s="202.197.78.129"; <BR>alert(isip(s)) <BR></script>
３．加sp1后还能用的无边框窗口！！

电话号码的验证
要求：
(1)电话号码由数字、"("、")"和"-"构成
(2)电话号码为3到8位
(3)如果电话号码中包含有区号，那么区号为三位或四位
(4)区号用"("、")"或"-"和其他部分隔开
(5)移动电话号码为11或12位，如果为12位,那么第一位为0
(6)11位移动电话号码的第一位和第二位为"13"
(7)12位移动电话号码的第二位和第三位为"13"
根据这几条规则，可以与出以下正则表达式：
(^[0-9]{3,4}\-[0-9]{3,8}$)|(^[0-9]{3,8}$)|(^\([0-9]{3,4}\)[0-9]{3,8}$)|(^0{0,1}13[0-9]{9}$)

具有在输入非数字字符不回显的效果，即对非数字字符的输入不作反应。

//Obj参数指定数据的来源(限定Table),默认第一行为字段名称行
//GetTableData类提供MoveNext方法,参数是表的行向上或向下移动的位数,正数向下移动,负数向上.
//GetFieldData方法获得指定的列名的数据
//Sort_desc方法对指定的列按降序排列
//Sort_asc方法对指定的列按升序排列
//GetData方法返回字段值为特定值的数据数组,提供数据,可以在外部进行其他处理
//Delete方法删除当前记录,数组减少一行
