    <script type="text/javascript">
    $(document).ready(function(){
        $('#selTrim').change(function(){
            var trim_id1 = $(this).val();
            if(trim_id1){
                $.ajax({
                    type:'POST',
                    url:'<?= base_url();?>H1_specifications/h1_trim_detail',
                    data:'trim_id1='+trim_id1,
                    success:function(data){
                        $('#specContWrap').html(data);
