使用JQuery和AJAX在Django中刷新div

// In my template
    var tag_cloud_floor = function(floor) {
    $.ajax({ url: "/{{ user }}/{{ tag }}/",data: {tag_cloud_floor: floor},type: 'POST',success: function(data) {
                         $('#tag_cloud).html(data);
                     },});

};

这是我的看法.

@login_required
def tag_page(request,username,tag):
  if username == request.user.username:
    tags = request.user.userprofile.tag_set.all()

    if request.is_ajax() and request.POST:
      floored_tags = []
      for t in tags:
        if t.item_set.all().count() >= int(request.POST['tag_cloud_floor']):
          floored_tags.append(t)
      tags = floored_tags

    tag = Tag.objects.get(title=tag)
    items = tag.item_set.all()
    return render_to_response("tag_page.html",{ 'user': request.user,'tag': tag,'tags': tags,'items': items })
  else:
  return httpResponseRedirect('/' + request.user.username + '/')

目前,它将整个html页面放入#tag_page div.我希望它用新的#tag_page div替换旧的#tag_page div.如果我替换$(‘#tag_cloud’).html(data); with $(‘body’).html(data);它刷新整个页面应该如何,但我觉得刷新整个页面是一种浪费.

如果有更好的方法,请告诉我.
