java代碼中郵箱正則表達式和js版

java代碼中：

/** 
     * 驗證Email 
     * @param email email地址，格式：[email protected]，[email protected]，xxx代表郵件服務商 
     * @return 驗證成功返回true，驗證失敗返回false 
     */   
    public static boolean checkEmail(String email) {   
        String regex = "\\w+([-+.]\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*";
        return Pattern.matches(regex, email);   
    } 

js版：

 

//jquery 驗證郵箱
 function checkEmail(email){
     if(isNull(email)){
        alert("郵箱不爲空");
         return false;


         }
var patten = new RegExp(/^[\w-]+(\.[\w-]+)*@([\w-]+\.)+[a-zA-Z]+$/);     
if(!patten.test(email)){

alert("請輸入合法的郵箱");
      return false;
}
return true ; 

}
