My get method is responding with JSON data that i want to render in a table.
This is the output when i console.log the variable declared i my get-method:
This is my controller method:
$scope.getProdukt = function (searchText, typeVariable) {
var results = produktService.searchPakninger(searchText, typeVariable);
angular.forEach(results,
function (value, key) {
console.log(key);
console.log(value);
console.log(value.status.status + ' her er status.status');
$scope.searchValue = value;
});
};
I can't seem to reference the object correctley to get the info i want. Bellow is the table I would like to render the data in. {{searchValue}} returns the entire object in one table cell. I also need an ng-repeat since there can be more than one object.
<table class="table" id="mixTables">
<thead>
<tr>
<th>GTIN</th>
<th>EPDNR</th>
<th>NAVN</th>
<th>Handling</th>
</tr>
</thead>
<tbody ng-if="!searchEmpty">
<tr ng-repeat="obj in searchValue">
<td>GTIN: nummer: {{obj.GTIN}}</td>
<td>Kategori navn: {{obj.KategoriNavn}}</td>
<td>Kategori kode: {{obj.KategoriKode}}</td>
<td><button class="btn btn-green pull-right" type="button" ng-click="addProdukt()">Velg <span class="fa fa-plus-circle"></span></button></td>
</tr>
</tbody>
</table>
I have updated my table, but no data is obj-data i rendered in the table. I dont think obj.GTIN is the right way to reference the data in the json object. The solutions with promises did not work in the controller.
------------------------------------------------------UPDATE------------------------------------------------------------------
I am also trying with a promise in the controller. Here is what i have so far:
$scope.getProdukt = function (searchText, typeVariable) {
var results2 = produktService.searchPakninger(searchText, typeVariable)
.then(function (response) {
var object = JSON.stringify(this.response);
//$scope.searchValue = response.data;
//$scope.isEmpty = false;
console.log('async promise = ' + object);
});
}
The console log prints out undefined for the object variable. I have been trying JSON.parse() as well, but with no luck. response.length is 1 or more for valid searchText.
I assume that your produktService.searchPakninge returns a html promise, so you have to use the .then function. You can then assign the results to a variable, and loop through them with ng-repeat:
$scope.getProdukt = function (searchText, typeVariable) {
produktService.searchPakninger(searchText, typeVariable)
.then(function(response) {
$scope.result = response.data;
});
};
And the view:
<tbody>
<tr ng-repeat="item in result">
<td>{{item.GTIN}}</td>
<td>{{item.Egenskaper}}</td>
<td>{{item.Markedsnavn}}</td>
<td><button class="btn btn-green pull-right" type="button">Velg <span class="fa fa-plus-circle"></span></button></td>
</tr>
</tbody>
Since you get your data in one cell I assume searchPakninger does not return a promise, so this should be enough:
<tbody>
<tr ng-repeat="obj in searchValue">
<td>{{obj.GTIN}}</td>
<td>{{obj.Egenskaper}}</td>
<td>{{obj.Markedsnavn}}</td>
<td>{{obj.KategoriNavn}}</td>
<td>{{obj.KategoriKode}}</td>
<td><button class="btn btn-green pull-right" type="button">Velg <span class="fa fa-plus-circle"></span></button></td>
</tr>
</tbody>
In case it returns a promise though, you should also transform your function as:
$scope.getProdukt = function (searchText, typeVariable) {
produktService.searchPakninger(searchText, typeVariable)
.then(function(response) {
$scope.result = response.data;
});
};

After I adding candidate, I believe that the $scope.candidates array is updated correctly, however the table in my view does not change. I don't know what i'm doing wrong.
Potential Issue
I think 'm_assesment_assesment_id' is stored as a String and not a Integer, which is the root of your problem.
[
{ "id":"14",
"m_assesment_assesment_id":"3", // Note: the numbers are wrapped in quotes
"percentage":"50"
},
{ "id":"15",
"m_assesment_assesment_id":"5", // JSON parsers will interpret these as Strings, NOT numbers
"percentage":"10"}
]
Background to Understanding Problem
Since the ng-repeat is using the item.m_assesment_assesment_id property, Angular resolves these as Strings. When this String is passed into the Array, the Array is interpreted as a JavaScript Object and not an array. For example:
// Both the following evaluate to the same thing
// Using dot accessor
item.m_assesment_assesment_id
// Using square brackets to access data through Object Notation
item["m_assesment_assesment_id"]
This is why JavaScript interprets your Array as an Object, using item.m_assesment_assesment_id as a key and not and index.
<!-- item.m_assesment_assesment_id will evaluate as a String as the JSON data specifies the String format, triggering Object evaluation, not Array evaluation -->
<tr ng-repeat="candidate in candidates[item.m_assesment_assesment_id]" class="well whel">
Here is some good overview of Array Evaluation:
https://www.w3schools.com/js/js_arrays.asp
Associative Arrays Many programming languages support arrays with
named indexes.
Arrays with named indexes are called associative arrays (or hashes).
JavaScript does not support arrays with named indexes.
In JavaScript, arrays always use numbered indexes.
Solutions
There are a couple of solutions. If you have access to manipulating the JSON formatting, I would recommend correcting the problem there:
{
"id":"14",
"m_assesment_assesment_id": 3, // No quote == Integer
"percentage":"50"
}
But this would require you to have access to the server code constructing the response and there may be architectural reasons for using a string.
Alternatively, you could change your ng-repeat:
<tr ng-repeat="candidate in candidates[parseInt(item.m_assesment_assesment_id)]" class="well whel">
However there is a performance loss as this requires more processing during Angular's $digest() event. This will not be significant for small datasets, but it is worth noting.
If you don't have access to changing the JSON formatting on the server and you don't want to put extra load on the $digest event, your control could process the response data from the AJAX calls. This is often the approach recommended by Angular documentation.
angular.module("selectionApp", ["isteven-multi-select"])
.controller('candidateCtrl', function ($scope, $http) {
$scope.candidates = [];
$scope.arrAddCandidate = [];
$scope.getPercentagePenilaian = function () {
var url = SITEURL + 'xxx/xxx/' + 14;
$http.get(url).then(function (response) {
// USE OUR CONVENIENCE METHOD HERE TO CONVERT STRINGS TO INTEGERS
$scope.percentage_penilaian = processPercentagePenilaian(response.data);
for(var i in response.data){
$scope.arrAddCandidate[response.data[i].m_assesment_assesment_id] = "addCandidate"+response.data[i].m_assesment_assesment_id;
}
})
};
// *** MORE of your code exists between these functions
// ALSO YOU HAVE TO CALL THIS IN THE CALLBACK OF THE APPROPRIATE AJAX CALLBACK
var processPercentagePenilaian = function(items) {
// Loop through the Items
angular.forEach(items, function(item, key) {
// For Every Item, convert the m_assesment_assesment_id to an Integer
item.m_assesment_assesment_id = parseInt(item.m_assesment_assesment_id);
});
// End Controller
});
I'm using Angular 1 with a factory that polls a REST API for JSON data. This JSON then populates a table with ng-repeat-start, and using ng-repeat-end I have a hidden table row with additional data.
Seems rather ordinary to me.
But the problem is, when I poll the API every 5 or 10 seconds, how can I keep the collapsible table row open when the next poll occurs?
In most cases the data does not change, so there's no reason to close the collapsible row, yet it closes at every poll that my factory makes.
Here's an example of one of the tables.
<table class="pure-table pure-table-horizontal alerts-table" id="alert-nagios-host-table">
<thead>
<tr>
<th>Hostname</th>
<th>Status</th>
<th>Output</th>
</tr>
</thead>
<tbody>
<tr class="parent-row" ng-repeat-start="alert in alerts" ng-click="child.expanded = !child.expanded">
<td>{{alert.hostname}}</td>
<td ng-class="{3:'grayBg', 2:'redBg', 1:'yellowBg', 0:'greenBg'}[alert.state]">{{alert.status}}</td>
<td>{{alert.output}}</td>
</tr>
<tr class="child-row" ng-init="child.expanded = false" ng-show="child.expanded" ng-repeat-end>
<td colspan=4>Duration: {{alert.duration}}</td>
</tr>
</tbody>
</table>
Here is my factory that polls the data, and an example of one of the angular controllers.
mondashApp.factory('AlertsPoller', function ($http, $timeout) {
var data = {resp: {}, count: 0};
var count=0;
var poller = function (url, success) {
count++;
$http.get(url).then(function (responseData) {
data.count = count;
data.resp = responseData.data;
success(data);
$timeout(function () {poller(url, success);}, 5000);
});
};
return {
poller: poller
};
});
mondashApp.controller('nagiosHostAlertsCtrl', function nagiosHostAlertsCtrl($scope, AlertsPoller) {
AlertsPoller.poller('/alert/nagios/host', function(response) {
$scope.alerts = response.resp.alerts;
});
});

I'm trying to fetch single record from datasource by Id in UI via Angular-js.
Using Web-API for retrieving values from DB.
To make it simple : HTML-->Angular-->WebAPI-->DB
When i'm trying it says Id passed is Null..Don't know how to rectify.
hope i've missed to fill hole in somewhere....below snippets fr ref.
(Also can u verify/correct me the way i've coded in html is right way to display values fetched by Id)
HTML :
<div ng-controller="SingleController">
<input type="text" ng-model="_Id" />
<input type="button" value="search" ng-click="search()" />

Please ignore this lengthy snippets.
Could you please help me on this.
Your search function is expecting you to pass a value when it is invoked on ng-click:
<input type="button" value="search" ng-click="search(_Id)" />
I'm trying to generate HTML table from json in AngularJS.
I receive JSON in format like this:
My Service for getting the data looks like this :
customAPI.getUsers = function() {
return $http({
method: 'JSONP',
url: 'http://arka.foi.hr/WebDiP/2013_projekti/WebDiP2013_069/api/admin/users.php'
});
};
and controller for that code looks like this
controller('usersController', function($scope, customAPIservice) {
$scope.filterName = null;
$scope.usersList = [];
/*Search*/
$scope.searchFilter = function(user) {
var keyword = new RegExp($scope.filterName, 'i');
return !$scope.filterName || keyword.test(user.korisnici.korisnik_ime) || keyword.test(user.korisnici.korisnik_prezime);
};
customAPIservice.getUsers().success(function(response) {
$scope.usersList = response.korisnici;
});
});
and my view looks like this :
<input type="text" ng-model="nameFilter" placeholder="Trazi..."/>
<h2 >Korisnici</h2>
<table>
<thead>
<tr>
<th colspan="6">Korisnici sustava</th>
</tr>
<th>Surname</th>
</thead>
<tbody>
<tr ng-repeat="user in usersList| filter: searchFilter">
<td>{{$index + 1}}</td>
<td>{{user.korisnik.korisnik_prezime}}</td>
<td>{{user.korisnik.korisnik_username}}</td>
</tr>
<tr ng-show="usersList == ''">
<td colspan="5">
<img src="img/ajax-loader.gif" />
</td>
</tr>
</tbody>
</table>
I think I messed up somewhere with binding the data with the view but I' still pretty new with angular so I can't find what is wrong. Also I've looked up over internet and couldn't find anything.Please help.
You are not correctly access the properties in your data. Use:
/*Search*/
$scope.searchFilter = function(user) {
var keyword = new RegExp($scope.filterName, 'i');
return !$scope.filterName || keyword.test(user.korisnik.korisnik_ime) || keyword.test(user.korisnik.korisnik_prezime);
};
I wrote a simple application to get JSON data from the sever
C# code
public JsonResult Read()
{
var products = db.Products;
return Json(GetProducts(), JsonRequestBehavior.AllowGet);
}
public IEnumerable<Product> GetProducts()
{
var data = db.Products.ToList();
return (data);
}
In the view i wrote the following to bind view model data.
<div>
<table data-bind="with: products">
<thead><tr><th>From</th><th>To</th><th>Subject</th></tr></thead>
<tbody data-bind="foreach: Object">
<tr>
<td data-bind="text: id"></td>
<td data-bind="text: name"></td>
<td data-bind="text: description"></td>
</tr>
</tbody>
</table>
</div>
<script type="text/javascript">
function ProductsViewModel() {
var self = this;
self.products = ko.observable();
$.getJSON("http://localhost:50998/Home/Read", function (data) {
self.products = JSON.parse(data);
});
}
ko.applyBindings(new ProductsViewModel());
</script>
The Json data return from action is as follows
[{"ID":1,"Name":"Roger","Description":"Test1"},{"ID":2,"Name":"Roger2","Description":"Test2"}]
After i have parse the JSON, i can't use the parsed object to update the observerable.
Does anyone know why this happens?
If you want to set the value of self.products (or the value of any other observable) to the result of JSON.parse you need to call it like this self.products(JSON.parse(data)). Observables are like functions so you need to treat them like functions ;-)
