django接收ajax请求,Django/AJAX：用POST发送和接收响应

今晚我第一次修改Javascript/JQuery、AJAX、JSON和GeoDjango，我完全搞砸了！在

到目前为止，我已经能够通过POST请求成功地从AJAX提交一个搜索查询，在Django中执行搜索，然后将序列化的数据传回AJAX。但是，我不知道如何用AJAX再次解码它！在

我收到这个错误：(Uncaught TypeError: Cannot read property length of undefined)

当我添加以下尝试处理数据时：$.each (json.results, function (i, val) {

//Loop through each returned item and push onto name

name.push(val.id);

//Loop through each returned item and push name onto var zip

zip.push(val.name);

});

我认为这就是相关的Ajax：

^{pr2}$

我的观点是以防万一：from django.shortcuts import HttpResponse

from django.views.generic import TemplateView

from django.core.serializers import serialize

from AlmondKing.Events.models import Event

from django.core.exceptions import SuspiciousOperation

class MapView(TemplateView):

template_name = "index2.html"

def post(self, request, *args, **kwargs):

if request.POST[event_search]:

self.object = Event.objects.search(request.POST[event_search])

return HttpResponse(serialize(geojson,self.object), content_type="application/json")

else:

raise SuspiciousOperation("Blank Request Received")

样本输出：b{"type": "FeatureCollection", "crs": {"type": "name", "properties": {"name": "EPSG:4326"}}, "features": [{"properties": {"tags": [], "name": "Party", "zip": "19146"}, "geometry": null, "type": "Feature"}, {"properties": {"tags": [], "name": "Jamboree", "zip": "19146"}, "geometry": null, "type": "Feature"}]}

我对如何帮助AJAX理解数据感到困惑。我使用POST以便在基于类的TemplateView中执行函数。然而，POST的AJAX设置似乎不能很好地解释序列化的响应。我怎么能一个请求就完成这些呢？在
