怎么样把这段搜索代码来设置搜索默认的值

现在，点击搜索按钮以后，然后直接就显示【音频】的结果去了，实际上应该是默认先显示到【视频】的结果上的，怎么样可以调整默认先显示到【视频】先。有没有大师帮我看看

    <div class="tab">
      <span data-media="video">视频</span>
      <span class="active" data-media="audio">音频</span>
      <span data-media="tuwen">图文</span>
    </div>
    
    
    <script>
    $(function(){
        var keyword="{$_GPC['keyword']}";
        var flid="{$_GPC['flid']}";
        var tid="{$_GPC['tid']}";
        tydata(tid,flid,keyword,'audio');
        //音视图点击
        $('.content .tab span').click(function(){
            var media=$(this).data('media');
            $(this).addClass('active').siblings().removeClass('active');
            tydata(tid,flid,keyword,media);
        })
    })
    function tydata(tid,flid,keyword,media) {
      var cont='';
      $.ajax({
            url:"{php echo $this->createMobileUrl('Tongyongdata');}",
            type:'GET',
            dataType:'json',
            data:{
                flid:flid,
                tid:tid,
                keyword:keyword,
                media:media
            },
            success:function(res){
                console.log(res)
                if(res.errno==0){
                  $.each(res.data, function(k, v) {
                    cont+="<a href="+(v.media=='tuwen'?"{php echo $this->createMobileUrl('mediadetail');}":"{php echo $this->createMobileUrl('mediamenu');}")+"&menuid="+v.id+"&media="+v.media+">"
                    cont+="<li class='sell-li'>"
                    cont+="<img class='sell-img' src={php echo $_W['attachurl']}"+v.thumb+" />"
                    cont+="<div class='sell-mess'>"
                    cont+="<p class='dec'>"+(v.menuname?v.menuname:v.tuwenname)+"</p>"
                    cont+="<p class='message'>"+(v.jianjie?v.jianjie:'')+"</p>"
                    cont+="<p class='message'>"
                    cont+="<img src='../addons/kuowan_video/template/mobile/img/book.png'>"+(v.ksnum?v.ksnum:1)+"课时"
                    cont+="</p>"
                    cont+="</div>"
                    cont+="</li>"
                    cont+="</a>"
                  });
                  if(cont!=''){
                    $(".wrapper-conter").html(cont);
                  }else{
                    $(".wrapper-conter").html("<h4 style='text-align:center;margin-top:1.2rem;'>暂无内容哦！</h4>");
                  } 
                }
            },
            error:function(res){
                
            }
        });
    }
</script>
