Javascript RegExp in Forms

[ExpDisease]

I cannot get the result right. I write area and phone by numbers but it still gives me error

Code: Select all

function validate_text(field,alerttext) {
   with(field) {
      
     var re = /[a-zA-Z]/g;
       if(re.test(field)) { return true;}else{alert(alerttext);return false;}
   }
}
function validate_number(field,alerttext){
     with(field) {
       
       var re = /[0-9]/g;
        if(re.test(field)) { return true;}else{alert(alerttext);return false;}
     }
}



function validateForm(thisForm){
   with(thisForm)
   {
      if(validate_number(area,"wrong area code") == false) {
      
         area.focus();return false;   
      }
      if(validate_number(phone,"wrong phone") == false) {
      
         phone.focus();return false;   
      }
      if(validate_text(name_surname,"wrong name") == false) {
      
         name_surname.focus();return false;   
      }

   }
}

Code: Select all

...<b>Name Surname :</b><input style="margin-left:10px;" type="text" name="name_surname"/>
<br /><br />
    <b>phone :</b><input type="text" style="margin-left:19px;" maxlength="4" size="4" name="area" />
-<input type="text" style="margin-left:5px;" maxlength="7" size="10" name="phone" /><br /><br />....
