Question

在页面加载时，我使用此代码显示数据库中的数据：

<script>

$(function feed(){

  var page = 1;
  var type = '<?php echo $filter ;?>';

  var theData = {};
  theData['page'] = 'profile';
  theData['type'] = type;
  theData['username'] = '<?php echo $user_data->username; ?>';
  theData['get_activities'] = 'true';

  $.ajax({
      type: "POST",
      url: "data.php",
      data: theData,
      dataType:'json',
      success: function(data){
          $("#activities").html(data.activity_feed);
          if(page < data.total_pages){
              $("#activities").after('<div id="loader"><button id="load_more_activities">Load more</button></div>');
          }
      }
  });
  $("#activity_container").on("click", "#load_more_activities", function(){
      var next = page+=1;
      var type = '<?php echo $filter ;?>';

      var theData = {};
      theData['page'] = 'profile';
      theData['type'] = type;
      theData['username'] = '<?php echo $user_data->username; ?>';
      theData['get_activities'] = 'true';
      theData['page_num'] = next;

      $.ajax({
          type: "POST",
          url: "data.php",
          data: theData,
          dataType: "json",

          success: function(data){
              $("#activities").append(data.activity_feed);
              if(next == data.total_pages){
                  $("#loader").html("No more data");
              } else {
                  $("#loader").html('<div id="loader"><button id="load_more_activities">Load more</button></div>');
              }
          },
      });
  });
});
</script>

一切正常，但如果我刷新页面超过5或6次，或者如果load_more_activities函数被调用超过5或6次......那么就不会执行post并且我没有显示任何数据...

此代码有问题，或者我的主机提供商可能有一些限制吗？
