我从 io.socket 接收数据，我想将数据放入对象数组中，以便可以在 slickgrid 中显示。由于某种原因，信息中推送的数据为空。有人可以帮我解决这个问题吗？

【解决方案1】：

当你更新 slickgrid 后面的数据时，你需要告诉网格用新数据重绘：

  socket.on('new message', function(data){
    $.each(data, function(idx, obj) {
      info.push(obj);
    });
    grid.invalidate(); // not 100% sure this is needed....
    grid.render();
  })
