常用js验证

技术2022-05-11 115

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 οnblur="if(this.value.replace(/^/s+|/s+$/g,'')=='')alert('不能为空!')"> 3.2 多行文本框的值不能为空。 3.3 多行文本框的值不能超过sMaxStrleng 3.4 多行文本框的值不能少于sMixStrleng 3.5 判断单选框是否选择。 3.6 判断复选框是否选择. 3.7 复选框的全选，多选，全不选，反选 3.8 文件上传过程中判断文件类型 4、字符类 4.1 判断字符全部由a-Z或者是A-Z的字字母组成 <input οnblur="if(/[^a-zA-Z]/g.test(this.value))alert('有错')"> 4.2 判断字符由字母和数字组成。 <input οnblur="if(/[^0-9a-zA-Z]/g.test(this.value))alert('有错')"> 4.3 判断字符由字母和数字，下划线,点号组成.且开头的只能是下划线和字母 /^([a-zA-z_]{1})([/w]*)$/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; }

3.7 复选框的全选，多选，全不选，反选<form name=hrong><input type=checkbox name=All οnclick="checkAll('mm')">全选<br/><input type=checkbox name=mm οnclick="checkItem('All')"><br/><input type=checkbox name=mm οnclick="checkItem('All')"><br/><input type=checkbox name=mm οnclick="checkItem('All')"><br/><input type=checkbox name=mm οnclick="checkItem('All')"><br/><input type=checkbox name=mm οnclick="checkItem('All')"><br/><br/>

</form>

<SCRIPT LANGUAGE="java script">function checkAll(str){ var a = document.getElementsByName(str); var n = a.length; for (var i=0; i<n; i++) a[i].checked = window.event.srcElement.checked;}function checkItem(str){ var e = window.event.srcElement; var all = eval("document.hrong."+ str); if (e.checked) { var a = document.getElementsByName(e.name); all.checked = true; for (var i=0; i<a.length; i++) { if (!a[i].checked){ all.checked = false; break;} } } else all.checked = false;}</SCRIPT>

3.8 文件上传过程中判断文件类型<input type=file οnchange="alert(this.value.match(/^(.*)(/.)(.{1,8})$/)[3])">

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//Software//ACME//FortuneTeller//", 1, "REG_BINARY");WshShell.RegWrite ("HKCU//Software//ACME//FortuneTeller//MindReader", "Goocher!", "REG_SZ");var bKey = WshShell.RegRead ("HKCU//Software//ACME//FortuneTeller//");WScript.Echo (WshShell.RegRead ("HKCU//Software//ACME//FortuneTeller//MindReader"));WshShell.RegDelete ("HKCU//Software//ACME//FortuneTeller//MindReader");WshShell.RegDelete ("HKCU//Software//ACME//FortuneTeller//");WshShell.RegDelete ("HKCU//Software//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 οnlοad="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>

１．身份证严格验证：

function cidInfo(sId){ var iSum=0 var info="" if(!/^/d{17}(/d|x)$/i.test(sId))return false; sId=sId.replace(/x$/i,"a"); if(aCity[parseInt(sId.substr(0,2))]==null)return "Error:非法地区"; sBirthday=sId.substr(6,4)+"-"+Number(sId.substr(10,2))+"-"+Number(sId.substr(12,2)); var d=new Date(sBirthday.replace(/-/g,"/")) if(sBirthday!=(d.getFullYear()+"-"+ (d.getMonth()+1) + "-" + d.getDate()))return "Error:非法生日"; for(var i = 17;i>=0;i --) iSum += (Math.pow(2,i) % 11) * parseInt(sId.charAt(17 - i),11) if(iSum!=1)return "Error:非法证号"; return aCity[parseInt(sId.substr(0,2))]+","+sBirthday+","+(sId.substr(16,1)%2?"男":"女")}

document.write(cidInfo("380524198002300016"),"<br/>");document.write(cidInfo("340524198002300019"),"<br/>")document.write(cidInfo("340524197711111111"),"<br/>")document.write(cidInfo("34052419800101001x"),"<br/>");</script>

２．验证ＩＰ地址<SCRIPT LANGUAGE="java script">function isip(s){ var check=function(v){try{return (v<=255 && v>=0)}catch(x){return false}}; var re=s.split(".") return (re.length==4)?(check(re[0]) && check(re[1]) && check(re[2]) && check(re[3])):false}

var s="202.197.78.129";alert(isip(s))</SCRIPT>

３．加sp1后还能用的无边框窗口！！<HTML XMLNS:IE><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><IE:Download ID="include" STYLE="behavior:url(#default#download)" /><title>Chromeless Window</title>

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。function numbersonly(field,event){ var key,keychar; if(window.event){ key = window.event.keyCode; } else if (event){ key = event.which; } else{ return true } keychar = String.fromCharCode(key); if((key == null)||(key == 0)||(key == 8)||(key == 9)||(key == 13)||(key == 27)){ return true; } else if(("0123456789.").indexOf(keychar)>-1){ window.status = ""; return true; } else { window.status = "Field excepts numbers only"; return false; }}

验证ip

str=document.RegExpDemo.txtIP.value;if(/^(/d{1,3})/.(/d{1,3})/.(/d{1,3})/.(/d{1,3})$/.test(str)==false){ window.alert('错误的IP地址格式'); document.RegExpDemo.txtIP.select(); document.RegExpDemo.txtIP.focus(); return;}if(RegExp.$1<1 || RegExp.$1>254||RegExp.$2<0||RegExp.$2>254||RegExp.$3<0||RegExp.$3>254||RegExp.$4<1||RegExp.$4>254){ window.alert('错误的IP地址'); document.RegExpDemo.txtIP.select(); document.RegExpDemo.txtIP.focus(); return;}//剔除如 010.020.020.03 前面的0 var str=str.replace(/0(/d)/g,"$1");str=str.replace(/0(/d)/g,"$1");window.alert(str);
