            alert('input is empty...');
            return false;
        } 
        else{
        $('[id^="hidden_div"]').hide();
            $('.div_search').show();                
            function loadData(page){
                $.ajax
                ({
                    type: "POST",
                    url: "load_data.php",
                    data: "page="+page+"&word="+searchWord,
                    success: function(msg)
                    {
