如何过滤关键字上的DIV内容

Question

我有一个搜索框，在其下输入用户。在此事件中，我试图仅显示div下的相关结果。

$(document).ready(function() { 
 
    $('#trainername').keyup(function() { 
 
     var tr = $('.trainers_listWrap li'); 
 
     if ($(this).val().length >= 2) { 
 
      var inputdata = $.trim($("#trainername").val()); 
 

 
      var noElem = true; 
 
      var val = $.trim(this.value).toLowerCase(); 
 
      el = tr.filter(function() { 
 
       return $(this).find('.mt-radio').text().toLowerCase().match("^" + val); 
 
      }); 
 
      if (el.length >= 1) { 
 
       noElem = false; 
 
      } 
 
      tr.not(el).fadeOut(); 
 
      el.fadeIn(); 
 
     } else { 
 
      tr.fadeIn(); 
 
     } 
 
    }) 
 
});
