js客户端验证

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

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


<input type=checkbox name=All2 onclick="checkAll('mm2')">全选<br/>
<input type=checkbox name=mm2 onclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 onclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 onclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 onclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 onclick="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 文件上传过程中判断文件类型
<input type=file onchange="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 onload="numberCells()">
<TABLE id=mytable border=1>
<TR><TH>&nbsp;</TH><TH>&nbsp;</TH><TH>&nbsp;</TH><TH>&nbsp;</TH></TR>
<TR><TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD></TR>
<TR><TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD></TR>
</TABLE>
</BODY>
</HTML>

１．身份证严格验证：

<script>
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 "}
  
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%11!=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>
