JS正则表达式

1）验证密码
   function verifyPassword(str){
      var reg=/^[A-Za-z0-9]+$/;
      if( reg.test(str) ){
          return true;
      }else{
          return false;
      }
   }

2）检查邮箱格式
   function verifyemail(str){
      var reg=/\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/;
      if( reg.test(str) ){
          return true;
      }else{
          return false;
      }
   }

/*****验证邮箱****/
function validateEmail(value){
return /^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?$/i.test(value);
}

3）检查值是否为空
   function checkIsNull(checkValue){
      if( checkValue.replace(/\s/g,"").length<1){
          return false;
      }else{
          return true;
      }
   }

4）检验邮编的格式
   function verifyPost(str) {
      var reg = /^[1-9][0-9]{5}$/;
      if( reg.test(str)) {
          return true;
      }else {
          return false;
      }
   }
5）检查身份格式
   function verifyCard(str){
      var reg= /^\d{18}|\d{15}$/   ;
      if( reg.test(str) ){
          return true;
      }else{
          return false;
      }
   }

6）检查下拉框的选项
   function checkSelected(checkValue){
      if( checkValue.replace(/\s/g,"").length<1 || checkValue == "-1"){
          return false;
      }else{
          return true;
      }
   }

7）验证手机号码的格式
   function verifyHandset(str) {
      var reg = /^(\+86)|(86)?1[3,5,8]{1}[0-9]{1}[0-9]{8}$/;
      if( reg.test(str)) {
          return true;
      } else {
          return false;
      }
   }

8）/*****验证用户名是否含有特殊符号****/
function validateSimpleName(value){
var re=/[\\:*;?"'$<>|]/;
if(value.match(re)){
return false;
}
return true;
}

9）/*****验证联系电话****/
function validateTelephone(value){
if(value=="格式：02585034082或13387723412"){
return true;
} else {
return /^((0(((\d{2,3})-(\d){7,8})|(\d{2,3}(\d){7,8})))|([1-9]\d{4,10}))$/.test(value);
}
}

电话号码正则表达式（支持手机号码，3-4位区号，7-8位直播号码，1－4位分机号）
   function verifyPhone(str) {
      var reg = /((\d{11})|^((\d{7,8})|(\d{4}|\d{3})-(\d{7,8})|(\d{4}|\d{3})-(\d{7,8})-(\d{4}|\d{3}|\d{2}|\d{1})|(\d{7,8})-(\d{4}|\d{3}|\d{2}|\d{1}))$)/;
      if( reg.test(str)) {
          return ture;
      } else {
          return false;
      }
   }

验证电话号码的格式
   function verifyPhone(str) {
      var reg = /($\d{3,4}$|\d{3,4}-|\s)?\d{7,8}/
      if( reg.test(str)) {
          return ture;
      } else {
          return false;
      }
   }

10、验证是否为正整数

function isPositiveInt(s){
var patrn=/^[0-9]*[1-9][0-9]*$/;
if (!patrn.exec(s)){
return false;
}
return true;
}

function checkAlumni(){
   var newPassword = document.getElementById("newPassword").value;
   var againNewPassword = document.getElementById("againNewPassword").value;
   if( newPassword != "" || againNewPassword != "") {
       if( newPassword.length <3 || newPassword.length >12){
           alert('密码长度不能小于3大于12!');
           document.getElementById("againNewPassword").value = "";
           document.getElementById("newPassword").focus();
           return false;
       }

       if( !verifyPassword(newPassword)){
           alert('密码应该由英文字母、0-9的数字组成!');
           document.getElementById("againNewPassword").value = "";
           document.getElementById("newPassword").focus();
           return false;
       }

       if( againNewPassword != newPassword) {
           alert('两次输入的密码不一致，请重新输入！');
           document.getElementById("againNewPassword").value = "";
           document.getElementById("newPassword").focus();
           return false;
       }
   }

   if( !verifyemail(document.getElementById("email").value)) {
       alert('请填写正确的邮箱格式!');
       document.getElementById("email").focus();
       return false;
   }

   if( !verifyPost(document.getElementById("postNumber").value)){
       alert('请填写正确的邮编格式!');
       document.getElementById("postNumber").focus();
       return false;
   }
   return true；
}
