ng-repeat for an json object which has arrays - angularjs

I have a JSON object which is data for a chart. This has 2 properties labels and data. Both are arrays. Along with the chart I wish to display a table as well. I am not able to figure out how to use the ng-repeat directive here.
JSON Object
$scope.chartdata={
labels: ["XYZ", "ABC","DEF"],
data: [4286, 38870, 3955]
};
HTML
<table class="table table-striped">
<thead>
<tr>
<th>Labels</th>
<th>Data </th>
</tr>
</thead>
<tr ng-repeat="cht in chartdata">
<td>{{cht.labels}}</td>
<td>{{cht.data}}</td>
</tr>
</table>
Do I need to change the JSON structure? I do not wish to cos it works for my chart directive and I want to resues the same JSON for displaying the table as well.

You need to use $index, because these are 2 separate properties within the chartdata object
<table class="table table-striped">
<thead>
<tr>
<th>Labels</th>
<th>Data </th>
</tr>
</thead>
<tr ng-repeat="label in chartdata.labels">
<td>{{label}}</td>
<td>{{chartdata.data[$index]}}</td>
</tr>
</table>
That said the object structure you have can probably be revised to be more like the model (unless you are using the object structure for something else that expects it in that format)
$scope.chartdata = [
{
label: "XYZ",
data: 4286
},
...
];
In the latter case too, you could use the above structure and set up a method that transforms the object into the dual array structure that you need for the something else.

I am trying to execute multiple ng-repeat so that I can access a third level array in my json and display in a table but can't get this working

I am trying to nest ng-repeat but looks like I am not doing it correctly.
I need all the lineItem in the json to be displayed.
Since, json value I am trying to display is a 3rd level array, I tried nested
ng-repeat but does not work.
<table border="1" width="100%">
<tr>
<th>Id</th>
<th>materialNumber</th>
<th>quantity</th>
</tr>
<tbody ng-repeat="subConfig in values.subConfigs.subConfig">
<tr ng-repeat="lineItem in subConfig.lineItems.lineItem">
<td>{{lineItem.lineItemId}}</td>
<td>{{lineItem.materialNumber}}</td>
<td>{{lineItem.quantity}}</td>
</tr>
</tbody>
</table>
here is jsfiddle I tried:
Your json was not in correct format values should not be array also you need to change ng-repeat="s in values.subConfigs.subConfig"> to ng-repeat="s in values.configBOM.subConfigs.subConfig">
Something like
<tbody ng-repeat="s in values.configBOM.subConfigs.subConfig">
<tr ng-repeat="lineItem in s.lineItems.lineItem">
<td>{{lineItem.lineItemId}}</td>
<td>{{lineItem.materialNumber}}</td>
<td>{{lineItem.quantity}}</td>
</tr>
</tbody>
Here is working fiddle
Its a very minor mistake :
Please change your json to an object instead of an array , the format you have given is wrong .
So it should be :
$scope.values={} //whatever you want to write inside
instead of:
$scope.value=[];
Secondly while you are doing ng-repeat you have to change this line :
<tbody ng-repeat="subConfig in values.subConfigs.subConfig">
to :
<tbody ng-repeat="subConfig in values.configBOM.subConfigs.subConfig">

display data angular 4 (converting obj to array)

I'm trying to display an object of an object in an array, I've been hitting my head against the wall since I cant change the backend.
this is what I got so far, M01, M02, M03... might refer to months since we are November there are 11 however if it was February id be only M01 and M02. since I got a property of an object I cant loop it on a second for and I'm having a lot of trouble with it
this is my view
<div *ngIf="estados" class="table-responsive col-lg-12 tablilla">
<table class="table table-bordered table-striped table-responsive">
<thead>
<tr>
<th></th>
<th *ngFor="let month of listaMonthsNames">{{month}}</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let estado of estados">
<td>{{estado.nom_item}}</td>
<td *ngFor="let month of estado.M[0]">{{month}}</td>
</tr>
</tbody>
</table>
</div>
I think this will help you :
There is no direct way to access Object from the Template side so,
All you need to do is provide Object.keys access to the Template side by this way from Component :
// Component Side :
objectKeys = Object.keys;
// Template Side :
<td *ngFor="let key of objectKeys(estado.M)">
Key: {{key}}, value: {{estado.M[key]}}
</td>

ng repeat dynamic with key objet json AngularJS

I have a small problem I would like to set up a ng-repeat dynamic with the values I receive from my JSON object,
First, i made my th from my table with the keys
Secondly, i would like to do my td in dynamic (without putting the name of the key ex: obj.NOM, obj.TYPE ...)
I managed to do something with an Object.keys but logic is not good so I need some help
this is my JSON object ( i show you just the little piece of code that I have a problem )
"HEADER":[
{"NOM":"API-APP","TYPE":"string","DESCRIPTION":"Code application"},
{"NOM":"API-SIGNATURE","TYPE":"string","DESCRIPTION":"Signature de la requete API"},
{"NOM":"API-TIMESTAMP","TYPE":"integer","DESCRIPTION":"Timestamp en microseconde"}]
and this is my ng repeat
<span><b>HEADER</b></span>
<br>
<br>
<table class="table">
<th ng-repeat ="(key, itemHeader) in itemHead.HEADER[0] track by $index">{{key}}</th>
<tr ng-repeat ="(key, itemHeader) in itemHead.HEADER track by $index" >
<td>{{getFirstPropertyValue(itemHeader,$index)}}</td>
</tr>
</table>
I explain i made first a ng-repeat for th with the keys and I would like put my data (3 data per row) in td without put ( .NOM .TYPE .DESCRIPTION)
So I took the function object.key which works very well but that makes me just one element per row but I need 3 elements per row
this is my scope for the function object.key
$scope.getFirstPropertyValue = function(obj,index){
return obj[Object.keys(obj)[index]];
}
and this my result
thanks in advance for your help
<table class="table">
<thead>
<tr>
<th ng-repeat="(key, itemHeader) in itemHead.HEADER[0]">
{{key}}
</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in itemHead.HEADER">
<td ng-repeat="column in row">
{{column}}
</td>
</tr>
</tbody>
</table>

How to iterate data in different tr in angular js

I am new to angular js .I want to iterate the below json in different tr. Currently i am getting the data in a single row by using ng-repeat.Is there is any by which i can set the data in different rows
{
"id": 2,
"project": "wewe2012",
"date": "2013-02-26",
"description": "ewew",
}
Required Output:
<tr>
<td>Emp id</td>
<td>Emp id</td>
</tr>
<tr>
<td>Project</td>
<td>wewe2012</td>
</tr>
<tr>
<td>date</td>
<td>2013-02-26/td>
</tr>
<tr>
<td>description</td>
<td>ewew</td>
</tr>
You do not need to use ng-repeat as you are not iterating over an object literal structure. As long as your view is bound to your controller, you can do the following. For the purposes of this example, I will assume your object is called exampleObject.
Note: If your object literal was an array of structures, you could use ng-repeat and iterate over the object to produce a view, however in this case, it is not necessary.
There is a post here explaining how to iterate over an object to create a table.
Object
var exampleObject = {
"id": 2,
"project": "wewe2012",
"date": "2013-02-26",
"description": "ewew",
}
View
<tr>
<td>Emp id</td>
<td>{{exampleObject.id}}</td>
</tr>
<tr>
<td>Project</td>
<td>{{exampleObject.project}}</td>
</tr>
<tr>
<td>date</td>
<td>{{exampleObject.date}}/td>
</tr>
<tr>
<td>description</td>
<td>{{exampleObject.description}}/td>
</tr>

Angularjs smart-table not sorting $index table cells

I have a problem withe the Smart Table AngularJS Sorting, I implemented this on my table as:
The initialized app:
angular.module('myproyApp', ['smart-table'])
The controller side:
$scope.dataList = []; //any json collection with: id, name and description
The view side with st-table directive:
<table class="table table-bordered table-striped" st-table="dataRows" st-safe-src="dataList">
<thead>
<tr>
<th><span class="glyphicon"></span>Q</th>
<th st-sort="name">Name</th>
<th st-sort="descripcion">Description</th>
<th>Actions</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in dataRows">
<td class="col-md-1">{{$index + 1}}</td>
<td class="col-md-4">{{row.name}}</td>
<td class="col-md-4">{{row.description}}</td>
<td>Change</td>
</tr>
</tbody>
</table>
On click the sorting header's cells the table is sorting, but the sorting isn't working for the $index cells. Please if you have any think to include the $index cells to sort. I want not to use the indexes on dataList $scope values, I need that this index will be include only on table view.
Track by is used to link your data with the DOM generation made by ng-repeat. When you add track by you tell angular to generate a single DOM element per data object in the given collection. Because $index has to do with the DOM there is no way to have it relate to a particular data entry. Here's a more detailed explanation.
If you really want to do it without touching your dataList, you could call indexOf in your table:
<tbody>
<tr ng-repeat="row in dataList | orderBy:sortField">
<td class="col-md-1">{{dataRows.indexOf(row)}}</td>
<td class="col-md-4">{{row.name}}</td>
<td class="col-md-4">{{row.description}}</td>
<td>Change</td>
</tr>
</tbody>
Where there is a scoped variable called sortField which is a string that is the name of the field you wish to sort by. I implemented a similar thing in this plunker, using the smart-tables module. http://plnkr.co/edit/AF90dQ
I would advise against this because it quickly becomes expensive for large arrays, and runs into problems if your entries aren't unique.
