2、电话号码，传真

 

Code  //校验普通电话、传真号码：可以“+”开头，除数字外，可含有“-”            function isTel(object)             {             //国家代码(2到3位)-区号(2到3位)-电话号码(7到8位)-分机号(3位)"              var s =document.getElementById(object.id).value;               var pattern =/^(([0\+]\d{2,3}-)?(0\d{2,3})-)(\d{7,8})(-(\d{3,}))?$/;              //var pattern =/(^[0-9]{3,4}\-[0-9]{7,8}$)|(^[0-9]{7,8}$)|(^\([0-9]{3,4}\)[0-9]{3,8}$)|(^0{0,1}13[0-9]{9}$)/;                  if(s!="")                  {                      if(!pattern.exec(s))                      {                       alert('请输入正确的电话号码:电话号码格式为国家代码(2到3位)-区号(2到3位)-电话号码(7到8位)-分机号(3位)"');                       object.value="";                       object.focus();                      }                  }             }

 

3、邮箱

 

Code  function Check(object)           {          var s =document.getElementById(object.id).value;               var pattern =/^[a-zA-Z0-9_\-]{1,}@[a-zA-Z0-9_\-]{1,}\.[a-zA-Z0-9_\-.]{1,}$/;                  if(s!="")                  {                      if(!pattern.exec(s))                      {                       alert('请输入正确的邮箱地址');                       object.value="";                       object.focus();                      }                  }                          }

Code  //校验手机号码：必须以数字开头，除数字外，可含有“-”             function isMobile(object)             {             var s =document.getElementById(object.id).value;              var reg0 = /^13\d{5,9}$/;             var reg1 = /^153\d{4,8}$/;             var reg2 = /^159\d{4,8}$/;             var reg3 = /^0\d{10,11}$/;             var my = false;             if (reg0.test(s))my=true;             if (reg1.test(s))my=true;             if (reg2.test(s))my=true;             if (reg3.test(s))my=true;                 if(s!="")                 {                     if (!my)                     {                        alert('请输入正确的手机号码');                        object.value="";                        object.focus();                     }                 }             }

 

 

Code  //校验日期            function isdate(object)             {              var s =document.getElementById(object.id).value;               var pattern =/^((\d{2}(([02468][048])|([13579][26]))[\-\/\s]?((((0?[13578])|(1[02]))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(3[01])))|(((0?[469])|(11))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(30)))|(0?2[\-\/\s]?((0?[1-9])|([1-2][0-9])))))|(\d{2}(([02468][1235679])|([13579][01345789]))[\-\/\s]?((((0?[13578])|(1[02]))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(3[01])))|(((0?[469])|(11))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(30)))|(0?2[\-\/\s]?((0?[1-9])|(1[0-9])|(2[0-8]))))))(\s(((0?[0-9])|([1-2][0-3]))\:([0-5]?[0-9])((\s)|(\:([0-5]?[0-9])))))?$/;                  if(s!="")                  {                      if(!pattern.exec(s))                      {                       alert('请输入正确的日期');                       object.value="";                       object.focus();                      }                  }                      }
