常用js驗證

一、驗證類
1、數字驗證內
  1.1 整數
      /^(-|/+)?/d+$/.test(str)
  1.2 大於0的整數 （用於傳來的ID的驗證)
      /^/d+$/.test(str)
  1.3 負整數的驗證
      /^-/d+$/.test(str)
2、時間類
  2.1 短時間，形如 (13:04:06)
      function isTime(str)
      {
        var a = str.match(/^(/d{1,2})(:)?(/d{1,2})/2(/d{1,2})$/);
        if (a == null) {alert('輸入的參數不是時間格式'); return false;}
        if (a[1]>24 || a[3]>60 || a[4]>60)
        {
          alert("時間格式不對");
          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})$/);
         if(r==null)return false;
         var d= new Date(r[1], r[3]-1, r[4]);
         return (d.getFullYear()==r[1]&&(d.getMonth()+1)==r[3]&&d.getDate()==r[4]);
      }
  2.3 長時間，形如 (2003-12-05 13:04:06)
      function strDateTime(str)
      {
        var reg = /^(/d{1,4})(-|//)(/d{1,2})/2(/d{1,2}) (/d{1,2}):(/d{1,2}):(/d{1,2})$/;
        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 只有小時和分鐘,形如(12:03)
3、表單類
  3.1 所有的表單的值都不能爲空
      <input οnblur="if(this.value.replace(/^/s+|/s+$/g,'')=='')alert('不能爲空!')">
  3.2 多行文本框的值不能爲空。
  3.3 多行文本框的值不能超過sMaxStrleng
  3.4 多行文本框的值不能少於sMixStrleng
  3.5 判斷單選框是否選擇。
  3.6 判斷複選框是否選擇.
  3.7 複選框的全選，多選，全不選，反選
  3.8 文件上傳過程中判斷文件類型
4、字符類
  4.1 判斷字符全部由a-Z或者是A-Z的字字母組成
      <input οnblur="if(/[^a-zA-Z]/g.test(this.value))alert('有錯')">
  4.2 判斷字符由字母和數字組成。
      <input οnblur="if(/[^0-9a-zA-Z]/g.test(this.value))alert('有錯')">
  4.3 判斷字符由字母和數字，下劃線,點號組成.且開頭的只能是下劃線和字母
      /^([a-zA-z_]{1})([/w]*)$/g.test(str)
  4.4 字符串替換函數.Replace();
5、瀏覽器類
  5.1 判斷瀏覽器的類型
      window.navigator.appName
  5.2 判斷ie的版本
      window.navigator.appVersion
  5.3 判斷客戶端的分辨率
      window.screen.height;  window.screen.width;
 
6、結合類
  6.1 email的判斷。
      function ismail(mail)
      {
        return(new RegExp(/^/w+((-/w+)|(/./w+))*/@[A-Za-z0-9]+((/.|-)[A-Za-z0-9]+)*/.[A-Za-z0-9]+$/).test(mail));
      }
  6.2 手機號碼的驗證
  6.3 身份證的驗證
      function isIdCardNo(num)
      {
        if (isNaN(num)) {alert("輸入的不是數字！"); return false;}
        var len = num.length, re;
        if (len == 15)
          re = new RegExp(/^(/d{6})()?(/d{2})(/d{2})(/d{2})(/d{3})$/);
        else if (len == 18)
          re = new RegExp(/^(/d{6})()?(/d{4})(/d{2})(/d{2})(/d{3})(/d)$/);
        else {alert("輸入的數字位數不對！"); 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("輸入的身份證號 "+ a[0] +" 裏出生日期不對！"); return false;}
        }
        return true;
      }

 

3.7 複選框的全選，多選，全不選，反選
<form name=hrong>
<input type=checkbox name=All οnclick="checkAll('mm')">全選<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/>

<input type=checkbox name=All2 οnclick="checkAll('mm2')">全選<br/>
<input type=checkbox name=mm2 οnclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 οnclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 οnclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 οnclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 οnclick="checkItem('All2')"><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 文件上傳過程中判斷文件類型
<input type=file οnchange="alert(this.value.match(/^(.*)(/.)(.{1,8})$/)[3])">

畫圖:
<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>

寫註冊表：
<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相關(客戶端動態增加行列）
<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>

１．身份證嚴格驗證：

<script>
var aCity={11:"北京",12:"天津",13:"河北",14:"山西",15:"內蒙古",21:"遼寧",22:"吉林",23:"黑龍江 ",31:"上海",32:"江蘇",33:"浙江",34:"安徽",35:"福建",36:"江西",37:"山東",41:"河南",42:"湖北 ",43:"湖南",44:"廣東",45:"廣西",46:"海南",50:"重慶",51:"四川",52:"貴州",53:"雲南",54:"西藏 ",61:"陝西",62:"甘肅",63:"青海",64:"寧夏",65:"新疆",71:"臺灣",81:"香港",82:"澳門",91:"國外 "}
 

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:非法地區";
 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%11!=1)return "Error:非法證號";
 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．驗證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>

電話號碼的驗證

要求：
　　(1)電話號碼由數字、"("、")"和"-"構成
　　(2)電話號碼爲3到8位
　　(3)如果電話號碼中包含有區號，那麼區號爲三位或四位
　　(4)區號用"("、")"或"-"和其他部分隔開
　　(5)移動電話號碼爲11或12位，如果爲12位,那麼第一位爲0
　　(6)11位移動電話號碼的第一位和第二位爲"13"
　　(7)12位移動電話號碼的第二位和第三位爲"13"
　　根據這幾條規則，可以與出以下正則表達式：
　　(^[0-9]{3,4}/-[0-9]{3,8}$)|(^[0-9]{3,8}$)|(^/([0-9]{3,4}/)[0-9]{3,8}$)|(^0{0,1}13[0-9]{9}$)

具有在輸入非數字字符不回顯的效果，即對非數字字符的輸入不作反應。
