 Q:

Validate multiple fields with same name jquery?

I have multiple select inputs in my page that are dynamically created with same name.
My code:
<select name="area[]" id="area[]" class="area">
    <option value="">Select Area</option>
    <?  
     $cities = $this->city_model->get_all($posters->product_id);
         foreach($cities as $city) {?>
           <option value="<?=$city->city_id?>"><?=$city->city_name?></option>
        <? }?>
 </select>

I want that user select a value from each select input, I am using jQuery function like this:
 $('.area').each(function(){ 
if($(this).val() == "") {
  alert("please select Area");
}  return false;
});

$('.quantity').each(function(){ 
if($(this).val() == "" || $(this).val() == 0) {
  alert("please select Quantity");
  return false;
}
});
$('#form').submit();

i did same same with it, it is also working, but it also submits the form as well, even i restrict it at
 <input type="submit" name="something" id="something" value="something" onclick="checkType();return false;">    

A:

You are missing a close brace on your if statement. Try this:
$('.area').each(function(){ 
   if($(this).val() === "") {
      alert("please select Area");
      return false;
   }
});

EDIT: I re-added the return false part, as it is likely the OP only wants to show 1 alert regardless of how many items are invalid.
Here is a working example

  Q: 

 Validate multiple field with same name jquery? 

 I have multiple choice remark in my page that are dynamically created with same name. 
 My code: 
 < choose name="area [ ] " id="area [ ] " class="area " > 
     < option value="">Select Area</option > 
     <?  
      $ cities = $ this->city_model->get_all($posters->product_id);

            < option value="<?=$city->city_id?>"><?=$city->city_name?></option > 
         <? }? > 
  < /select > 

 I desire that exploiter select a value from each blue-ribbon input, I am using jQuery routine like this: 
  $ (' .area').each(function () { 
 if($(this).val () = = " ") { 
   alert("please choice Area "); 
 }   return false; 
 }); 

 $ (' .quantity').each(function () { 
 if($(this).val () = = " " || $ (this).val () = = 0) { 
   alert("please select Quantity "); 
   return delusive; 
 } 
 }); 
 $ (' # form').submit (); 

 i did same same with it, it is besides working, but it also put in the class as well, even i qualify it at 
  < input type="submit " name="something " id="something " value="something " onclick="checkType();return false; " >

 You are missing a airless brace on your if statement. Try this: 
 $ (' .area').each(function () { 
    if($(this).val () = = = " ") { 
       alert("please select Area "); 
       render false;
