刷新使用jQuery和AJAX在Django一个div [英] Refresh a div in Django using JQuery and AJAX
问题描述
我想刷新我与AJAX和JQuery的(在Django)网页的某一部分。我怎样才能得到它重新显示只有DIV,而不是整个页面。
I am trying to refresh a certain part of my page with AJAX and JQuery (in Django). How can I get it to redisplay only the div, rather than the whole page.
// 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);
},
});
};
下面是我的看法。
@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,它把整个HTML页面到#tag_page股利。我想它来代替旧的#tag_page分区与新的#tag_page股利。如果我更换 $('#tag_cloud)HTML(数据);
与 $(身体)HTML(数据);
它刷新整个页面就应该是这样,但我想刷新整个页面是一种浪费。
Currently, it places the entire html page into the #tag_page div. I want it to replace the old #tag_page div with the new #tag_page div. If I replace $('#tag_cloud').html(data);
with $('body').html(data);
it refreshes the whole page to how it should be, but I figure refreshing the whole page is a waste.
如果有更好的方法来做到这一点,让我知道。
If there is a better way to do this, let me know.
推荐答案
首先,它看起来像你的code坏了 - 这不是一个有效的JavaScript / jQuery的指令:
First, it looks like your code is broken - this is not a valid Javascript/jQuery instruction:
$('#tag_cloud').html(data);
对于只刷新一个 DIV
,我会提取该div的内容到一个单独的模板 my_div.html
,使用包括它的主要页面模板{%包括my_div.html%}
。然后,在我的AJAX的看法,我会渲染和只返回呈现 my_div.html
。
As for refreshing only a single div
, I would extract contents of that div to a separate template my_div.html
, include it in the main page template using {% include "my_div.html" %}
. Then, in my AJAX view, I would render and return only that rendered my_div.html
.
