Parsing JSON result to object by using checkbox

I have loaded a JSON list into a table and I would like to parse 1 JSON result or multiple results into an object, so I can send it to the server.
My table looks like this so far:
HTML
<tr ng-repeat="t in student">
<td ng-model="herkanserNaam">{{ t.Name }}</td>
<td>{{ t.City }}</td>
<td>
<div class="checkbox" ng-click="laatzien(herkanserNaam, herkanserCheck)" ng-model="herkanserCheck">
<label>
<input type="checkbox">
</label>
</div>
</td>
</tr>
Controller
$scope.laatzien = function(name, active) {
var herkanser = [{
"name" : name,
"active" : false
}];
console.log(herkanser);
}
How would I be able to check one or multiple results and save the data(t.Name) into an object by using a checkbox? So far the function laatzien() is returning the empty values defined in herkanser.

The reason your laatzien method is failing is due to how you are using your directives. Let's work with the example you provided to get your laatzien method to fire.
HTML
<tr ng-repeat="student in students">
<td>{{ student.Name }}</td>
<td>{{ student.City }}</td>
<td>van</td>
<td>Huis</td>
<td>j.huis#student.han.nl</td>
<td>
<div class="checkbox">
<label>
<input type="checkbox" ng-model="student.isActive" ng-change="laatzien(student)">
</label>
</div>
</td>
</tr>
Javascript
$scope.laatzien = function (student) {
var herkanser = [{
"name": student.name,
"active": student.isActive
}];
console.log(herkanser);
}
I have made some opinionated changes in your example for readability purposes, others were needed to get the directives to fire as expected. Below are the changes to your snippets.
Renamed the student array to students. This will require a change in your controller from $scope.student to $scope.students.
Renamed the t object to student.
Removed the ng-click directive from your div.
Added an ng-change directive on your checkbox. Now when you click the checkbox your laatzien method should fire.
Added an isActive property to your student. Inside of your laatzien method, you may now check the state of the checkbox. If the checkbox is checked, student.isActive = true. If the checkbox is not checked, student.isActive = false.

From your code, you seem to want to build the "list of checked students" and send that to the server. In other words, what you want, is to allow the user to check on multiple students and at the end collect everything that was checked and send it over to the server.
If that's the case then your strategy to put an ng-click over the checkbox is wrong.
What you need is to bind your checkbox to your $scope model. Such as this:
<input type="checkbox" ng-model="t.isChecked" ng-true-value="true" ng-false-value="false'">
When the user checks the checkbox for a student. Your model will automatically be updated.
To collect the data to send over the server you need to put an ng-click on a submit button. In the event handler, simply loop through every student in your $scope "students" model and only save the ones that have isChecked property to true to be sent over to the server.
Hope this helps!

You could make a function to push thet item into an obj like so...
$scope.students = [
{
"name":"John",
"city":"Boston"
},
{
"name":"Amy",
"city":"Dallas"
}
]
$scope.activeObj = [];
$scope.laatzien = function(obj) {
if($.inArray(obj, $scope.activeObj) == -1) {
$scope.activeObj.push(obj);
} else {
var index = $scope.activeObj.indexOf(obj);
$scope.activeObj.splice(index, 1);
}
}

Filter separate variable in Angular

So I have some code that looks like this:
<input ng-model="search" type="text">
<td ng-repeat="key in targets">
{{ display_names[key] }}
</td>
To be more clear:
targets is a variable containing not-human readable ids such as key012
display_names is an object which has keys like: key012: "USA"
I would like to filter the display_names value from the search? Looking at the angularjs docs, I know I can filter key, but I haven't figured out how to filter display_names
Example
Here's a full example:
var TS = angular.module('myapp', []);
TS.controller('test', function($scope) {
$scope.targets = ["id_1", "id_2"];
$scope.display_names = {
"id_1": "USA",
"id_2": "Mexico"
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="myapp" ng-controller="test">
<input ng-model="search" placeholder="Search...">
<ul>
<li ng-repeat="key in targets">{{display_names[key]}}</li>
</ul>
</body>

<td ng-repeat="key in targets">
<span ng-if="display_names[key].indexOf(search) > -1">{{ display_names[key] }}</span>
</td>
use ng-if, or you could also use ng-show. Differences here
This way, as you write in search (which should be in $scope.search) angular will refresh the ng-repeat values to show
If you want to search it case-insensitive, you could use toLowerCase() function before using indexOf
display_names[key].toLowerCase().indexOf(search) > -1

You can't use a filter | in the html because you don't have the value you want to filter against in the array you are iterating over. Instead you can use ng-if to show/hide the elements based on the search. Something like:
<div ng-repeat="key in targets" ng-if="!search || !!display_names[key].match(search)">
{{ display_names[key] }}
</div>
The !! boolean cast is done because otherwise a new Regex object will be returned for the match which triggers a digest cycle which will return another new object and so on.
You also probably want to iterate over <tr> rather than <td>, and you need a <table> element for these elements to be allowed.
Example: http://plnkr.co/edit/qrpLKD9x4IBXowpIgnrf?p=preview
You could also write a custom filter for this, but it is a lot more work:
.filter('displayNames' function () {
return function (key, names, search) {
return !search || !!names[key].match(search);
};
});
And use it like key in targets | displayNames:display_names:search

How to ng-repeat array of an object in object?

I have this data:
{
"order":[
{
"id":1,
"table":1,
"foods":"{'foods':[{'id':2, 'name':'Nasi Minyak', 'qty':1}]}",
"drinks":"{'drinks':[{'id':1,'name':'Teh O Ais','qty':1}]}",
"waiter":"ali",
"foods_status":0,
"drinks_status":0,
"created_at":"2015-07-12T00:30:52.637Z",
"updated_at":"2015-07-12T00:30:52.637Z"
},
{
"id":2,
"table":2,
"foods":"{'foods':[{'id':2, 'name':'Nasi Goreng', 'qty':1}]}",
"drinks":"{'drinks':[{'id':1,'name':'Milo Ais','qty':1}]}",
"waiter":"abu",
"foods_status":0,
"drinks_status":0,
"created_at":"2015-07-12T00:51:43.552Z",
"updated_at":"2015-07-12T00:51:43.552Z"
}
]
}
I try to grab all foods name inside table like this:
<table class="table-bordered table table-striped">
<thead>
<tr>
<td>#</td>
<td>Name</td>
<td>Action</td>
</tr>
</thead>
<tbody>
<tr ng-repeat="order in orders">
<td>{{order.id}}</td>
<td>{{order.foods.name}}</td>
<td>
<button class="btn btn-danger" ng-click="">Delete</button>
</td>
</tr>
</tbody>
</table>
And this is my $http.get to get the data:
$http.get("../api/orders")
.success(function(data) {
var order = data.order;
$scope.orders = order;
});
I managed to bind the id but I could't bind the name inside the foods array.
How to get the name inside the foods array of this data?
Plunker:

You need another ng-reapeat. Something like this:
<tr ng-repeat="order in orders">
<td>{{order.id}}</td>
<td>
<span ng-repeat="item in order.foods.foods">{{item.name}}/</span>
</td>
<td>
<button class="btn btn-danger" ng-click="">Delete</button>
</td>
</tr>
Another consideration is about the format of your JSON. this line:
"foods":"{'foods':[{'id':2, 'name':'Nasi Minyak', 'qty':1}]}"
the way it is, "foods" is holding a String, and not a Object. To make the ng-reapeat work, you will need to force JSON from string using
JSON.parse(jsonString);
or change your JSON to:
"foods":{"foods":[{"id":2, "name":"Nasi Minyak", "qty":1}]}
Side note, why repeat the keys "foods" and "drinks"? Doesn't seem logic to me. Change your data structure to:
"order":[
{
"id":1,
"table":1,
"foods":[{"id":1, "name":"Nasi Kerabu", "qty":1},{"id":2, "name":"Nasi Minyak", "qty":1}],
"drinks":[{"id":1,"name":"Sirap Ais","qty":1},{"id":2, "name":"Milo Ais", "qty":1}],
"waiter":"ali",
"foods_status":0,
"drinks_status":0,
"created_at":"2015-07-12T00:30:52.637Z",
"updated_at":"2015-07-12T03:30:35.684Z"
},
...
]
and use:
<td> <span ng-repeat="item in order.foods">{{item.name}}</span> </td>
Here is a plunker with these modifications:
http://plnkr.co/edit/UVvCVzh4hbsEwolyWpDs?p=preview

Here is a plunker that works http://plnkr.co/edit/snE9Em0tCKh0nUHIlTFn?p=preview.
Consider modifying your JSON file. Use double quotation marks instead of single quotation marks.
In your modified JSON file in your new plunker remove double quotations marks here "[{'id':1,

I have made some changes in your data and it fix the issue you are facing.
Here is plunker link
`http://plnkr.co/edit/nxBGMMyuNIzUOvQAu7YY?p=preview`

Each order would be an object like this:
{
"id":2,
"table":2,
"foods":"{'foods':[{'id':2, 'name':'Nasi Goreng', 'qty':1}]}",
"drinks":"{'drinks':[{'id':1,'name':'Milo Ais','qty':1}]}",
"waiter":"abu",
"foods_status":0,
"drinks_status":0,
"created_at":"2015-07-12T00:51:43.552Z",
"updated_at":"2015-07-12T00:51:43.552Z"
}
Note that foods points to an object, whose only key 'foods' points to an array... whose first component should be an object. However, if you read more closely:
"foods":"{'foods':[{'id':2, 'name':'Nasi Goreng', 'qty':1}]}",
Notice the double quotes surrounding foods's value? They mean that it points to a String instead of an object.
First, you need to delete the double quotes surrounding the values of both foods and drinks:
"foods":{'foods':[{'id':2, 'name':'Nasi Goreng', 'qty':1}]},
"drinks":{'drinks':[{'id':1,'name':'Milo Ais','qty':1}]},
And then replace all the single quotes with double ones, to make the object comply with the JSON object definition:
"foods":{"foods":[{"id":2, "name":"Nasi Goreng", "qty":1}]},
"drinks":{"drinks":[{"id":1,"name":"Milo Ais","qty":1}]},
Now, to get 'name', you need to access order.foods.foods[0].name instead of order.foods.name.

orderBy in ng-repeat

JS:
$scope.termexamlist = {
0:{
0id:"1",
1name:"Doe, John",
2term1:"89"
},
1:{
0id:"2",
1name:"Aayt, Ray",
2term1:"90"
}
};
HTML:
<tr ng-repeat="t in termexamlist">
<td ng-repeat="(key,value) in t">{{value}}</td>
</tr>
i got this ng-repeat code which generates list of students with their term exam grades, i want to sort it by 1name but it didnt work i use to put <tr ng-repeat="t in termexamlist | orderBy:'1name' "> but it didnt work. i tried different codings too but it didnt work either. Sorry im just a beginner in angularjs programming. Thanks for the help :D

You should not have put identifiers when you declared your array
$scope.termexamlist = [
{
0id:"1",
1name:"Doe, John",
2term1:"89"
},
{
0id:"2",
1name:"Aayt, Ray",
2term1:"90"
}
];
This will be enough and enable you to iterate through it and ordering it.
Also, it's strange the way you prefix your variables, but that's none of my business

$scope.termexamlist = [
{
0id:"1",
1name:"Doe, John",
2term1:"89"
},
{
0id:"2",
1name:"Aayt, Ray",
2term1:"90"
}
];
remove 0 and 1 in your data , it will work fine

i got it now, i add underscore to the key of the object so it will look like this $scope.termexamlist={0:{_0id:"1",_1name:"Doe, John",_2term1:"89"}}. i retain the number coz chrome sort the returned data of json_encode

Looping over an ArrayController fails as it is not an Array even though the Controller has the correct model with data

I am attempting to use an ArrayController to handle displaying some data that will be swapped out on user clicks. I currently get this error, Uncaught Error: Assertion Failed: The value that #each loops over must be an Array. You passed App.CurrentListController but If I look at Ember Inspector I can see the CurrentListController and it has the model and the data in it. Basically the Stat page lets you see a bunch of stats and clicking on a specific stat pops up a modal and shows all the record that relate to that stat. If I just store the records on the StatController it works fine but then I cant sort/filter using the ArrayController. So it all works except for when I try and display the contents of CurrentListController it freaks out.
Thanks for any help or direction.
CurrentListController:
App.CurrentListController = Ember.ArrayController.extend({
sortProperties: ['name'], //Initial sort column.
sortAscending: true,
});
StatController:
App.StatController = Ember.ObjectController.extend({
needs:['currentList'],
currentList:[],
actions: {
viewBusiness: function(ids) {
console.log(ids)
var self = this
console.log(this.get('controllers.currentList').get('sortProperties'))
this.store.findByIds('business', ids.split(",")).then(
function(results)
{
$('#editModal').modal('show');
//self.set('currentList', results.sortBy(["name"]))
self.get('controllers.currentList').set('model', results)
console.log(self.get('controllers.currentList').get('arrangedContent'))
});
},
sortBy: function(prop){
var clController = this.get('controllers.currentList')
clController.set('sortProperties', prop)
clController.set('sortAscending', !clController.get('sortAscending'));
}
}
});
Stat Template:
{{#each business in App.CurrentListController}}
<tr {{bind-attr id=business.id}}>
<td>{{business.name}}</td>
<td>{{business.city}}</td>
<td>{{business.state}}</td>
<td>{{business.zip}}</td>
<td class="text-center">{{business.numVendors}}{{/link-to}}</td>
<td class="text-center">{{business.numClients}}{{/link-to}}</td>
</tr>
{{/each}}

App.CurrentListController is not an array. It's an object, a controller object. (btw it is not recommended to access the global namepsace [ ie. using anything with an uppercase letter ] in your template)
What you should do instead is:
App.StatController = Ember.ObjectController.extend({
needs:['currentList'],
currentList: Ember.computed.alias('controllers.currentList.model'),
...
This way you can access the underlying model of your currentList controller (which is an array) and make it available to your template as currentList.
{{#each business in currentList}}
...
{{/each}}
