If a frontend library needs a to parse JSON, you can use the json library to convert a python dict to a JSON valid string. Use the escapejs filter import json def foo(request): json_string = json.dumps(<time_series>) render(request, “foo.html”, {‘time_series_json_string’: json_string}) <script> var jsonObject = JSON.parse(‘{{ time_series_json_string | escapejs }}’); </script>
The JSON string you have is an array with 1 object inside of it, so to access the object you have to access the array first. With a json.php that looks like this: [ { “iId”: “1”, “heading”: “Management Services”, “body”: “<h1>Program Overview</h1><h1>January 29, 2009</h1>” } ] I just tried this $.getJSON(“json.php”, function(json) { alert(json[0].body); … Read more
I quickly set up this project and I was able to successfully call my web method, please adjust your code accordingly. Make sure your class property names are the same as the ones that you pass through JavaScript. Webservice public static Contact getContact(Contact cnt) { cnt.name = “Abijeet Patro”; cnt.phone = “Blah Blah”; return cnt; … Read more
I’d happily use JavaScriptSerializer – but if in doubt, consider a third option – Json.NET. Because it is 3rd party, it is unrelated to the MS decisions… that is a double-edged sword, of course – but it is often easier to get a minor fix applied to a standalone 3rd-party libary.
You should override the shouldOverrideUrlLoading method of WebViewClient @Override public boolean shouldOverrideUrlLoading (WebView view, String url) { if(flag) { URL aURL = new URL(url); URLConnection conn = aURL.openConnection(); conn.connect(); InputStream is = conn.getInputStream(); // read inputstream to get the json.. … … return true; } return false } @override public void onPageFinished (WebView view, String … Read more
Since myJSONObject.abc contains a list of products it would make more sense to define the property abc as an array. Like this: var myJSONObject = { “abc”: [ [ {“prod_ver” : “prod 1 ver 1”}, {“prod_ver” : “prod 1 ver 2”}, ], [ {“prod_ver” : “prod 2 ver 1”}, {“prod_ver” : “prod 2 ver 2”}, … Read more
By default, Json.NET ignores the Serializable attribute. However, according to a comment to this answer by Maggie Ying (quoted below because comments are not meant to last), WebAPI overrides that behavior, which causes your output. Json.NET serializer by default set the IgnoreSerializableAttribute to true. In WebAPI, we set that to false. The reason why you … Read more
You should look into loading assets in flutter. You can’t simply import an arbitrary file. Importing is for source code/libraries. You need to declare this file as an asset in your pubspec.yaml flutter: assets: – json_data.json Then in your code you can load this asset as a String: import ‘package:flutter/services.dart’ show rootBundle; Future<String> getJson() { … Read more
Assume , the JSON output is outJSON = [ { team: “TeamA”, name: “Ahmed”, field3:”val3″ }, { team: “TeamB”, name: “Ahmed”, field3:”val43″ }, { team: “TeamA”, name: “Ahmed”, field3:”val55″ }, ] Then see the groupBy function in the DEMO below: DEMO : outJSON = [{ team: “TeamA”, name: “Ahmed”, field3: “val3” }, { team: “TeamB”, … Read more
Since OS X El Capitan, Apple introduced System Integrity Protection which restricts writing to /usr/lib /usr/bin and other sensitive directories (even to root or sudo user) that are used by the installation of Perl bundled with the Operating System. This can cause issues when it comes to installing new modules and also if trying to … Read more
