dJango template 和 view 沟通的新做法

主要是view中的函数可以直接返回，作为http的response：
view中：

return JsonResponse({'pathname': pathName, 'polygon': json.dumps(originGpxManager.GetPolygon(pathName))}) 

template中：

//send to serversfunction reqListener() {console.log(typeof(this.responseText),typeof(this.response));console.log(this)var response = JSON.parse(this.responseText);console.log(response);var pathName = decodeURI(response['pathname']);var polygon = response['polygon'];console.log('pathName', pathName);//add polygon to gpxmanagerpathManger.AddOriginPolygon(pathName, polygon);}var oReq = new XMLHttpRequest();oReq.addEventListener("load", reqListener);oReq.open("GET", 'decodePathLine_toPolygon' + '/'+pathname+'/' + str_paths);oReq.send();
