模态框获取id一直不变，都是同一个id值

$('.refund-btn').click(function(){
    //此处必须是$(this),否则$('.refund-btn')重新获取，导致值一直不变
    var id = $(this).attr('data-id');
    //var id = $('.refund-btn').attr('data-id');错误，这样会导致一直一个id值，一直不变，需要用$(this).attr('data-id')
    var form = $('#refund-order-form');
    form.attr('action', form.attr('action').replace('__order_id__', id));
    
    $.get('{$ajaxRefundInfoUrl}'.replace('__id__', id),function(rs){
        if(rs.status==200){
            //默认为订单金额
            $('#refundorderform-refund_amount').val(rs.model.price);
            $('#refundorderform-refund_reason').val(rs.model.refund_reason);
            $('#refundorderform-is_cancel').val(rs.model.is_cancel);
            $('#refundorderform-refund_explain').val(rs.model.refund_explain);
            $('#refundorderform-refund_remark').val(rs.model.refund_remark);
        }
    },'json');
    
});
