When I use ajax to submit a comment form in Django,the page will redirect to a blank page shows me the success data:

```
{"status":"success", "msg":"添加成功"}

```

,but not stay in current page.I want the page stay in current page and show me the new comment.

Here is my update\_comment view:

```
def update_comment(request, news_pk):
    news = get_object_or_404(News, id=news_pk)
    comment_form = CommentForm(request.POST or None)
    if request.method == 'POST' and comment_form.is_valid():
        if not request.user.is_authenticated:
            return render(request, 'login.html', {})
        comments = comment_form.cleaned_data.get("comment")
        news_comment = NewsComments(user=request.user, comments=comments, news=news)
        news_comment.save()

    # return redirect(reverse('news:news_detail', kwargs={'news_pk': news.id}))
        return HttpResponse('{"status":"success", "msg":"添加成功"}', content_type='application/json')
    else:
        return HttpResponse('{"status":"fail", "msg":"添加失败"}', content_type='application/json')

```

Here is my ajax:

```
$(document).on('submit', 'comment_form', function(e){
        e.preventDefault();

        $.ajax({
            cache: false,
            type: "POST",
            url:"{% url 'operation:update_comment' news.id %}",
            data:{'news_pk':{{ news.id }}, 'comments':comments},
            async: true,
            beforeSend:function(xhr, settings){
                xhr.setRequestHeader("X-CSRFToken", "{{ csrf_token }}");
            },
            success: function(data) {
                if(data.status == 'fail'){
                    if(data.msg == '用户未登录'){
                        window.location.href="login";
                    }else{
                        alert(data.msg)
                    }
                }else if(data.status == 'success'){
                    window.location.reload();//refresh current page.
                }

                },
        });
    });

```

Here is my form:

```
<form id="comment_form" action="{%  url 'operation:update_comment' news.id %}" method="POST" >
{% csrf_token %}

<textarea id="comment_textarea"name="comment"></textarea>

<input type="submit" value="Submit"> </input>

</form>

```
