Nested JSON data source with DataTables

I have JSON data source with nested obvar
jsonData = {
"block":[
{"name": "Block 1. Social Work",
"subblock": [{
"name": "Block 1.1. Student Org (SO)",
"paragraph": [
{
"name": "Head of SO",
"score": "10,00"
}, {
"name": "Head of Group" ,
"score": "9, 00 "
}]
}]
}]
};
Wher block.name = table caption, subblock.name =
var subbl_content=document.createElement("th");
subbl_content.colSpan=4;
subbl_content.innerHTML=jsonData[0].block[0].subblock[0].name;
paragraph = table content. I try to place it to DataTable in the following way
$(document).ready(function() {
.....
$('#example').DataTable(
{
data: jsonData,
columns: [
{ data: 'block[0].subblock[0].paragraph[0].name' },
{ data: 'block[0].subblock[0].paragraph[0].score' }
]
});
}) ;
It would seem that must work but as a result i have in one Cell next value Head of SOiHead of Group. But when i some change data like
$('#example').DataTable(
{
data: jsonData.block[0].subblock[0].paragraph,
columns: [
{ data: 'name' },
{ data: 'score' }
]
});
All works. Is it normal or are there other methods of solution?

Change Image when Page Refresh in angularJS

This is on of tough task that am facing in my school. am totally new to angularJs. i need to fetch one image out of all retrieved images from the database. And then when i refresh the page the next image want to appear.
for an example first "banner.jpg" appear when i refresh the page "banner1.jpg" want to appear. can anyone help me to do solve this problem. please.
This is my retrieved Json
{
"id": 1,
"path": "Content/Banner/banner.jpg"
},
{
"id": 2,
"path": "Content/Banner/banner1.jpg"
},
{
"id": 3,
"path": "Content/Banner/banner2.jpg"
},
{
"id": 4,
"path": "Content/Banner/banner3.jpg"
},
my angular controller.
appGM.controller('bannerCtrl', ['$scope', '$http', 'urls', function ($scope, $http, urls) {
var request = $http({
method: 'GET',
url: urls.api + 'Banner/Banners'
}).success(function (data, status) {
console.log(data);
console.log(JSON.stringify(data));
console.log(JSON.parse(JSON.stringify(data)));
$scope.BBanner = angular.fromJson(data);
})
.error(function (error) {
$scope.status = 'Unable to load dog images: ' + error.message;
console.log($scope.status);
});
And its my Html
<div class="row">
<div class="col-sm-3 sidenav" ng-repeat="d in BBanner">
<img ng-src="{{d.path}}">
</div>

you can use localstorage to store the in in the first time. After you refresh the page increment the value and save it to the same local storage and so on.
run this Demo multiple time to see the id change.
controller
if(!localStorage.getItem("uID")){
var s = {"id":1};
localStorage.setItem("uID", JSON.stringify(s))
}
$scope.data = [{
"id": 1,
"path": "Content/Banner/banner.jpg"
},
{
"id": 2,
"path": "Content/Banner/banner1.jpg"
},
{
"id": 3,
"path": "Content/Banner/banner2.jpg"
},
{
"id": 4,
"path": "Content/Banner/banner3.jpg"
}]
var item = localStorage.getItem("uID")
item = JSON.parse(item);
alert("Id = " + item.id)
item.id = item.id +1 ;
localStorage.setItem("uID", JSON.stringify(item))
$scope.clear = function(){
localStorage.removeItem("uID");
}
updated
add this to check the image. check the demo again
var item = localStorage.getItem("uID")
item = JSON.parse(item);
var obj = $scope.data.find(function(o){
return o.id === item.id
})
// add this lines
$scope.image =(obj)? obj.path : "invalid id";
if(item.id == 4){
localStorage.removeItem("uIDs");
item.id = 0;
}
item.id = item.id +1 ;

angularjs ng-repeat drop down menu from json nested

I have the following example.json file:
[
{
"interests": [
{
"item": "art"
},
{
"item": "literature"
},
{
"item": "history"
},
{
"item": "science"
}
]
},
{
"experience": [
{
"year": "novice"
},
{
"year": "experienced"
}
]
}
]
and in my view controller, I read the file like this:
app.controller('ProfileCtrl', ["$scope", "$state", "$http",
function ($scope, $state, $http) {
$http.get('files/example.json').success(function (data)
{
$scope.myjsonobj= data;
});
and in my html view, I am injecting the values like this:
<div ng-controller="ProfileCtrl">
...
<select class="form-control" ng-model="user.favs">
<option ng-repeat="p in interests.myjsonobj" value="{{p.item}}">{{p.item}}</option>
</select>
question:
How can I show only the list of values of "interests" in my dropdown menu? How can I access the nested json array in angularjs?
my current setup is not working.

assuming 'interests' is your controller shortname.
you can use:
<option ng-repeat="p in myjsonobj[0].interests" value="{{p.item}}">{{p.item}}</option>
Ideally, you should loop the data object to find the index with the 'interests' key vs hardcoding [0].
update: removed "interests." from the repeat. doesn't seem like you have the ctrl shortname binding.

I'm not an angular guy. But with my javascript knowledge it seems to me that the
"interests.myjsonobj"
should be
"myjsonobj.interests"

How to get back an array of objects which have a particular value using filters in AngularJS?

var foo = [
{
"id": 12,
"name": "Test"
},
{
"id": 2,
"name": "Beispiel"
},
{
"id": 3,
"name": "Sample"
},
{
"id": 4,
"name": "Test"
},
{
"id": 5,
"name": "Sample value"
},
{
"id": 6,
"name": "Testvalue"
}
];
I am trying to get a simple search input, which shows a couple of listings on ng-repeat. The search is basically a filter which shows searched items in that listing. What I have achieved is when I search something, with $http, it gets back the whole list of foo, and within that it filters. How can I just get the data with my keyword, and the whole JSON? For example if I search sample, how can I get the objects of id 3 and 5 so that I can display a new set of listings, or if I search with ID number 12, I get the object which has id as 12. The search term will be dynamic. I will be giving a $http call on every search as well.
Thanks.

If I understood well, it should work:
(function() {
angular
.module('app', [])
.controller('MainCtrl', MainCtrl);
MainCtrl.$inject = ['$scope', '$http'];
function MainCtrl($scope, $http) {
$scope.foo = [
{
"id":12,
"name":"Test"
},
{
"id":2,
"name":"Beispiel"
},
{
"id":3,
"name":"Sample"
},
{
"id":4,
"name":"Test"
},
{
"id":5,
"name":"Sample value"
},
{
"id":6,
"name":"Testvalue"
}
];
}
})();
<!DOCTYPE html>
<html ng-app="app">
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.8/angular.min.js"></script>
</head>
<body ng-controller="MainCtrl">
<input type="text" ng-model="search" placeholder="Search">
<ul>
<li ng-repeat="item in foo | filter: search">
<span ng-bind-template="{{item.id}} - {{item.name}}"></span>
</li>
</ul>
</body>
</html>
Note: If you want to perform a $http request based on search input, look at this DEMO.

You can use $filter to achieve this.
function YourController($filter) {
var result = $filter('filter')(foo, {"id":3,"id":5});
};
You can iterate result later.

Proper display of layered json data

I have json that looks like this:
[
{
"Id": 1,
"Name": "Item1",
"Order": 1,
"Categories": [
{
"Id": 1,
"Name": "Item1-Subitem1",
"Order": 1,
"Subcategories": [
{
"Id": 1,
"Name": "Item1-Subitem1-Subsubitem1",
"Order": 2
},
{
"Id": 2,
"Name": "Item1-Subitem1-Subsubitem2",
"Order": 1
},
...
and with angular I need to display on first page (or route) link on main items. For example:Item1Item2And when clicked on them links should be displayed with names from 'Categories'For example:Item1-Subitem1Item1-Subitem2And when clicked on these links there should be displayed links with name from 'Subcategories'For example:Item1-Subitem1-Subsubitem1Item1-Subitem1-Subsubitem2
Now my first links work but I don't know how to get that nested data from same json according to value from url. When I click on links in first view I go to page I need but without data. No errors is displayed. I belive I need to parse id from url but how to achieve that?

In secondList.js, you've defined your scope with the wrong name. It should be:
scope: {
secondList: '='
},
After you fix that, you're also missing the final factory in service.js:
app.factory('singleList', ['$http', function ($http) {
return {
get: function () {
return $http.get('data.json').then(function (re) {
return re.data;
});
}
};
}])
