带有jquery的序列化参数，用于ajax

Question

I need help to prepare parameters for $.ajax submit.

I have multiple pairs of html inputs (i pairs):

> <input type="hidden" value="31" name="product_id"> <input
> type="hidden" value="3" name="quantity">
> 
> <input type="hidden" value="34" name="product_id"> <input
> type="hidden" value="1" name="quantity">

if I use this jquery code:

   function send(){      

   var parameter1 =$("input[name$='product_id']").serialize();
   var parameter2 = $("input[name$='quantity']").serialize();

  $.ajax({
   type: "POST",
   url: 'index.php?route=checkout/cart/add', 
   data: parameter1+'&'+parameter2  
  });
};

I send parameters like this:

product_id=31&product_id=30&quantity=2&quantity=2

How pass parameters like this:

product_id=31&quantity=2&product_id=30&quantity=2

Thanks

Answer 1

if you want parse them in same order they are in html do

data = '';
$('input[type="hidden"]').each(function(){
    data += '&' + $(this).attr('name') + '=' + $(this).attr('value');'
});
