我已经构建了一个ajax帖子,我通过它将一些数据发送到另一个PHP文件,最后进行实时搜索……但事情是它有点慢,当我在框内输入内容时,ajax占用1 -2秒即可开火….我希望搜索类似于youtube的搜索或FaceBook搜索,非常快,当我在那里输入内容时会立即显示建议…任何想法如何解决这个问题？

这是代码：

$("#seArch").keyup(function(){
            VAR value = $(this).val();
            var categ = $("#categ").val();
                if (value.length >= 1)
                {
                    $.ajax({
                       tyPE: "POST",url: "../core/search.PHP",data: { string : value,categ : categ },success: function(result){ 
                            $(".each_movie").hide();
                            $(".search_movie").remove();
                            $("#movies").append(result);
                       }
                    });
                }
                else
                {
                        $(".each_movie").show();
                        $(".search_movie").remove();
                }
    });

和PHP

$src = $_POST['string'];
$categ = $_POST['categ'];

$sql = MysqL_query("SELECT * From movies WHERE `$categ` LIKE '%".$src."%' ") or die(MysqL_error());
while ($sql_grab = MysqL_fetch_assoc($sql))
{
    ?>
        <div class="search_movie">
         <p style="margin-bottom:5px;font-family:'Lucida Sans Unicode','Lucida Grande',sans-serif;color:rgba(255,255,0.3);font-Size:12px;">Din: <?PHP echo $sql_grab['airdate']; ?> in cinematografe.</p>
        <table>
            <tr>
                <td rowspan="2" valign="top"><img class="main_pic" src="<?PHP echo $sql_grab['mainpic']; ?>" width="180px" /></td>
                <td><p class="name"><?PHP echo $sql_grab['name']; ?></p></td>
            </tr>
            <tr>
                <td><div class="desc_wrapper" id="<?PHP echo $id; ?>" style="display:inline-block;"><p class="desc"><?PHP echo MysqL_real_escape_string($sql_grab['description']); ?></p></div><p nr="<?PHP echo $id; ?>" id="more<?PHP echo $id; ?>" class="more" style="posITion:absolute;margin:30px 2px;color:rgba(255,0.2);cursor:pointer;display:inline-block">...citeşte</p></td>
            </tr>
        </table>
        </div><!--each movie end-->
    <?PHP   
}
