JS代码大全
一、验证类 1、数字验证内 1.1 整数 /^(-|\+)?\d+$/.test(str) 1.2 大于0的整数 （用于传来的ID的验证) /^\d+$/.test(str) 1.3 负整数的验证 /^-\d+$/.test(str) 2、时间类 2.1 短时间，形如 (13:04:06) function isTime(str) 
{ 
var a = str.match(/^(\d{1,2})(:)?(\d{1,2})\2(\d{1,2})$/); if (a == null) {alert('输入的参数不是时间格式'); return false;} 
if (a[1]>24 || a[3]>60 || a[4]>60) { alert("时间格式不对"); return false 
} return true; 
} 2.2 短日期，形如 (2003-12-05) function strDateTime(str) { var r = str.match(/^(\d{1,4})(-|\/)(\d{1,2})\2(\d{1,2})$/); if(r==null)return false; var d= new Date(r[1], r[3]-1, r[4]); return (d.getFullYear()==r[1]&&(d.getMonth()+1)==r[3]&&d.getDate()==r[4]); } 2.3 长时间，形如 (2003-12-05 13:04:06) function strDateTime(str) { var reg = /^(\d{1,4})(-|\/)(\d{1,2})\2(\d{1,2}) (\d{1,2}):(\d{1,2}):(\d{1,2})$/; var r = str.match(reg); if(r==null)return false; var d= new Date(r[1], r[3]-1,r[4],r[5],r[6],r[7]); return (d.getFullYear()==r[1]&&(d.getMonth()+1)==r[3]&&d.getDate()==r[4]&&d.getHours()==r[5]&&d.getMinutes()==r[6]&&d.getSeconds()==r[7]); } 2.4 只有年和月。形如(2003-05,或者2003-5) 2.5 只有小时和分钟,形如(12:03) 3、表单类 3.1 所有的表单的值都不能为空 <input onblur="if(this.value.replace(/^ +| +$/g,'')=='')alert('不能为空!')"> 3.2 多行文本框的值不能为空。 3.3 多行文本框的值不能超过sMaxStrleng 3.4 多行文本框的值不能少于sMixStrleng 3.5 判断单选框是否选择。 3.6 判断复选框是否选择. 3.7 复选框的全选，多选，全不选，反选 3.8 文件上传过程中判断文件类型 4、字符类 4.1 判断字符全部由a-Z或者是A-Z的字字母组成 <input onblur="if(/[^a-zA-Z]/g.test(this.value))alert('有错')"> 4.2 判断字符由字母和数字组成。 <input onblur="if(/[^0-9a-zA-Z]/g.test(this.value))alert('有错')"> 4.3 判断字符由字母和数字，下划线,点号组成.且开头的只能是下划线和字母 /^([a-zA-z_]{1})([\w]*)$/g.test(str) 4.4 字符串替换函数.Replace(); 5、浏览器类 5.1 判断浏览器的类型 window.navigator.appName 5.2 判断ie的版本 window.navigator.appVersion 5.3 判断客户端的分辨率 window.screen.height; window.screen.width; 6、结合类 6.1 email的判断。 function ismail(mail) { return(new RegExp(/^\w+((-\w+)|(\.\w+))*\@[A-Za-z0-9]+((\.|-)[A-Za-z0-9]+)*\.[A-Za-z0-9]+$/).test(mail)); } 6.2 手机号码的验证 6.3 身份证的验证 function isIdCardNo(num) { if (isNaN(num)) {alert("输入的不是数字！"); return false;} var len = num.length, re; if (len == 15) re = new RegExp(/^(\d{6})()?(\d{2})(\d{2})(\d{2})(\d{3})$/); else if (len == 18) re = new RegExp(/^(\d{6})()?(\d{4})(\d{2})(\d{2})(\d{3})(\d)$/); else {alert("输入的数字位数不对！"); return false;} var a = num.match(re); if (a != null) { if (len==15) { var D = new Date("19"+a[3]+"/"+a[4]+"/"+a[5]); var B = D.getYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5]; } else { var D = new Date(a[3]+"/"+a[4]+"/"+a[5]); var B = D.getFullYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5]; } if (!B) {alert("输入的身份证号 "+ a[0] +" 里出生日期不对！"); return false;} } return true; } 画图: <OBJECT id=S style="LEFT: 0px; WIDTH: 392px; TOP: 0px; HEIGHT: 240px" height=240 width=392 classid="clsid:369303C2-D7AC-11D0-89D5-00A0C90833E6"> </OBJECT> <SCRIPT> S.DrawingSurface.ArcDegrees(0,0,0,30,50,60); S.DrawingSurface.ArcRadians(30,0,0,30,50,60); S.DrawingSurface.Line(10,10,100,100); </SCRIPT> 写注册表： <SCRIPT> var WshShell = WScript.CreateObject("WScript.Shell"); WshShell.RegWrite ("HKCU\ oftware\\ACME\\FortuneTeller\\", 1, "REG_BINARY"); WshShell.RegWrite ("HKCU\ oftware\\ACME\\FortuneTeller\\MindReader", "Goocher!", "REG_SZ"); var bKey = WshShell.RegRead ("HKCU\ oftware\\ACME\\FortuneTeller\\"); WScript.Echo (WshShell.RegRead ("HKCU\ oftware\\ACME\\FortuneTeller\\MindReader")); WshShell.RegDelete ("HKCU\ oftware\\ACME\\FortuneTeller\\MindReader"); WshShell.RegDelete ("HKCU\ oftware\\ACME\\FortuneTeller\\"); WshShell.RegDelete ("HKCU\ oftware\\ACME\\"); </SCRIPT> TABLAE相关(客户端动态增加行列） <HTML> <SCRIPT LANGUAGE="JScript"> function numberCells() { var count=0; for (i=0; i < document.all.mytable.rows.length; i++) { for (j=0; j < document.all.mytable.rows(i).cells.length; j++) { document.all.mytable.rows(i).cells(j).innerText = count; count++; } } } </SCRIPT> <BODY onload="numberCells()"> <TABLE id=mytable border=1> <TR><TH> </TH><TH> </TH><TH> </TH><TH> </TH></TR> <TR><TD> </TD><TD> </TD><TD> </TD><TD> </TD></TR> <TR><TD> </TD><TD> </TD><TD> </TD><TD> </TD></TR> </TABLE> </BODY> </HTML>
