Simple angular example not working: ng-repeat + GET - angularjs

I am trying to iterate with ng-repeat, using data served from a REST service.
It works perfectly when the data is a single Json object, but when it comes to be a list of objects the HTML doesn't get the data.
Here is the code:
hello.js
function Hello($scope, $http) {
$http({ method: 'GET', url: 'http://devfz.azurewebsites.net/api/providers' }).
success(function (data) {
$scope.providers = [data];
}).
error(function () {
alert("Error");
});
}

<div ng-controller="Hello">
<table class="table table-striped table-condensed">

<tr>
<th style="min-width: 80px;">Id</th>
<th style="min-width: 80px;">Name</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="provider in providers">
<td>{{provider.id}}</td>
<td>{{provider.name}}</td>
</tr>
</tbody>
</table>
</div>
</div>
</div>
</body>
</html>
Thanks so much :)

Your providers array contains a single element:
$scope.providers = [data]; // array containing a single element: data
If a JSON array is returned by the server, and you want to iterate over that array, then the code should be
$scope.providers = data;

after the controller definition make array providers
$scope.providers = [];
and in success callback concat data.
.success(data) {
$scope.providers = $scope.providers.concat(data)
}

i click button reset class not work, why? who can tell me. thanks very much!!
You don't need that directive (and you don't need to manipulate the DOM yorself). ng-class is itself a built-in directive that does just that.
Just delete your myTd directive and change your element to this:
<td ng-class="{'selected':selectClass}" ng-repeat="item in tableData" ng-click="selectClass = !selectClass" >{{item}}</td>
Actually what you want to do to achieve your requirement by preserving the directive is to remove the class selected from your table rows
To do that modify the reset function as follows
$scope.reset = function(){
$('.selected').removeClass('selected');
}
This function selects all the elements with class name selected and will remove the class from those elements

Angularjs is not displaying update data in table row, ng-repeat not working properly?

Place ng-controller inside the <body> tag.
You used it in the <div> which is closed, so it's can't be available to the rest bottom of the code.
<body ng-controller="nodeappctrl">
//your code here..
</body>
The problem is here:
<div class="container" ng-controller="nodeappctrl">
The nodeappctrl controller should be applied to a tag that is a parent of where you're accessing its scope. As you can see, the table is a child of a sibling of the element the controller is bound to.
For example, move ng-controller="nodeappctrl" to the body tag.

but i am not getting the data when i tried to use bullet chart, other wise i am getting data. when i am using http call for data rather than json object, following error is coming.click here for error page
Here is a simplified version of what I think you were trying to achieve. I don't quite get the .finally() function in your code, so what I do instead is map $scope.jsondata to $scope.transactionData, creating a chartData property within each item, so that when you ng-repeat over them, you can feed each of the nvd3 bullet charts its own data object.
I believe the errors you were getting were caused by the fact that you were trying to feed string values of actualVolume and expectedVolume to nvd3, so I fixed that by converting them to Number values instead:
chartData: {
ranges: [100, 150, Number(record.expectedVolume)*1.5],
measures: [Number(record.actualVolume)],
markers: [Number(record.expectedVolume)]
}
See the rest below... Hope this helps you.
var app = angular.module('plunker', ['nvd3']);
app.controller('MainCtrl', ['$scope', function ($scope) {
$scope.jsondata = [
{
'transactionName': '1',
'actualVolume':'150',
'expectedVolume':'300'
},
{
'transactionName': '2',
'actualVolume':'250',
'expectedVolume':'300'
}
];
$scope.transactionData = $scope.jsondata.map(function(record) {
return {
transactionName: record.transactionName,
actualVolume: record.actualVolume,
expectedVolume : record.expectedVolume,
chartData: {
ranges: [100, 150, Number(record.expectedVolume)*1.5],
measures: [Number(record.actualVolume)],
markers: [Number(record.expectedVolume)]
}
};
});
$scope.options1 = {
chart: {
type: 'bulletChart',
transitionDuration: 500
}
};
}]);

how to read json data from server using angularJs in eclipse?

Hers is my code in html pasted in WebContent folder created using Dynamic Web Project in eclipse:
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.min.js"></script>
<script>
var countryApp = angular.module('countryApp', []);
countryApp.controller('CountryCtrl', function ($scope, $http){
$http.get('country_codes.json').success(function(data) {
$scope.countries = data;
});
});
</script>
</head>
<body ng-controller="CountryCtrl">
<h2>Angular.js JSON Fetching Example</h2>
<table>

<tr ng-repeat="country in countries | orderBy: 'code' ">
<td>{{country.code}}</td>
<td>{{country.name}}</td>
<td>{{country.population}}</td>

The json data is written in "country_codes.json" which is placed at the same location where html file has been placed.

But I am getting the output as shown in below image.Please let me know why it is not reading data from server
you missed ng-app directive

How to display single column data in tabular format with angularjs?

My REST API returns hundreds rows of data that looks something like this:
[
{"roman_number":"I"},
{"roman_number":"II"},
{"roman_number":"III"},
{"roman_number":"IV"}
{"roman_number":"V"},
{"roman_number":"VI"},
{"roman_number":"VII"},
{"roman_number":"VII"},
...
{"roman_number":"MMI"}
]
I'd like to be able to display the data in table like so ...
<table border=1>
<tr><td>I</td><td>II</td><td>III</td><td>IV</td></tr>
<tr><td>V</td><td>VI</td><td>VII</td><td>VIII</td></tr>
<tr><td>IX</td><td>X</td><td>XI</td><td>XII</td></tr>
<tr><td>XIII</td><td>XIX</td><td>XX</td><td>XXI</td></tr>
<tr><td colspan=4> pagination here </td></tr>
</table>
I hope that I do this in angular as I am using angular HTTP to communicate with my REST API. Thanks.
Updated based on Partha Sarathi Ghosh suggestion.
I have this app file:
var app = angular.module("myApp", ['smart-table']);
angular.module('myApp').filter('chunkby', function() {
return function(input, chunk) {
var i,j,temparray=[];
if(! input ) { return; }
for (i=0,j=input.length; i<j; i+=chunk) {
temparray.push(input.slice(i,i+chunk));
}
return temparray;
};
});
... and I have this html ...
<table>
<tr ng-repeat="row in (all_types|chunkby:5)">
<td ng-repeat="col in row">{{col}}</td>
</tr>
</table>
... but I get this error in my console ...
Error: [$rootScope:infdig] ...
... but the data displays ok. I noticed that the plunker demo also gets this error too.
Try this custom filter
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.data = [0,1,2,3,4,5,6,7,8,9,10,11, 12,13,14,15];
});
angular.module('plunker').filter('chunkby', function() {
return function(input, chunk) {
var i,j,temparray=[];
for (i=0,j=input.length; i<j; i+=chunk) {
temparray.push(input.slice(i,i+chunk));
}
return temparray;
};
});
