I write ajax on my page, to get subcategories in select option, depending on categories option list click. In all browsers it works good, i can see my request, response in browsers console... but in chrome functions even doesn`t call. Dou you know, in what the problem is? Here is my code:

    <td>

      <span style=color: #898989;>Main categories</span>

      <br />

      <select style=width: 200px;>

        <?foreach ($main_categories as $item){?>

        <option onclick=get_sub_cat(<?=$item['id']?>,2);return false; value=<?=$item['id']?>><?=$item['title']?></option>

        <?}?>

      </select> 

    </td>

    <td>

      <span style=color: #898989;>Subcategories</span>

      <br />

      <select  name=sub_cat style=width: 200px; id=prod_subcat_2>

      </select> 

    </td>





function get_sub_cat(id, select_id){

$.ajax({

   type: POST,

   url: <?=base_url()?>admin/product/get_sub_cat/+id,

   data: ,

   success:function (option_list) {

     $(#prod_subcat_+select_id).children().remove();

     $('#prod_subcat_'+select_id).append(option_list);

   }

 });

}
