I am trying to fetch data in AngularJS using Http Get request. I have created a separate controller.js file where I have implemented Http get service.
I have created a database.json file within the app.When I am trying to run my app on http-server, I am unable to fetch data from the data file created.
I am getting the following error in my console.
index.html:

</li>
</ul>
</div>
</body>
</html>
controller.js:
var app = angular.module("myApp", [ ]);
app.controller('datactrl', function($scope, $http) {
$http.get('http://127.0.0.1/AngularJS/HttpGet/database.json')
.then(function(response) {
$scope.persons = response.records;
});
});
database.json:
{
"records": [
{
"Name" : "asd",
"Age" : "20"
},
{
"Name" : "asd",
"Age" : "20"
},
{
"Name" : "asd",
"Age" : "20"
}
]
}
Can anybody please help me to resolve this issue..?

I want to be able to dynamically filter by the user clicking the button repersenting who's specific phone number they would like to see instead of using "filter: {Name: 'Bob'}" only showing Bobs info but I have not been able to find a way to use a variable in place of 'Bob'. I have provided the code in images.
Plunker was right in how I use a variable in my filter, I just did what Shb said in the comments as well so my buttons were out of scope and I just adjusted the tags ng-app and ng-controller to the body and Punkers solution to the filter works. Thanks guys something I should have easily seen.

I am looking at this tutorial. And I have such code:
<!DOCTYPE html>
<html lang="en" ng-app="">

<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $http) {
$http.get("http://localhost:8080/book_store/rest/books_json/get")
.then(function(response) {
$scope.books = response.data;
});
});
</script>
<div ng-app="myApp" ng-controller="myCtrl">
<input id="filter_input" type="text" ng-model="nameText"/>
<ul>
<li ng-repeat="book in books | filter:nameText | orderBy:'name'">
{{book.name}} - {{book.price}}
</li>
</ul>
</div>
</body>
</html>
http://localhost:8080/book_store/rest/books_json/get is returning following json:
[
{
"book_id":1,
"name":"Book1",
"bought":false,
"genre":"MR",
"price":20,
"users":[
],
"author":{
"author_id":1,
"name":"Gogol",
"books":[
]
}
},
//...
]
But I see in a browser networking that request wasn't fire. What have I done wrong?
Remove the ng-app="" from the html tag or provide the module name ng-app="MyApp".
Also remove one of the ng-app directives either from the the body tag or the html tag.
It is good practice to user the ng-app directive on the HTML tag if you are using just one angular app.
Goole chrome is giving this error

But I am able to see "left image" fine when the app is run.

The browser is trying to load your unparsed template variable as a url before the desired item.image value is substituted in.
You can fix this by using ng-src instead of src on your image tag: https://docs.angularjs.org/api/ng/directive/ngSrc.
I have created a simple demoapp and it seems to work perfectly file.
The demoapp uses restangular for the get request.
/* the emp.json file from where the data is coming*/
[
{"id":1,
"subject":"#aashima"
},
{"id":2,
"subject":"#aansh"
},
{"id":3,
"subject":"#artle"
},
{"id":4,
"subject":"#harish"

The app works perfectly but the problem in here is that the json response from my backend will be something like this
{"user":[
{"id":1,
"subject":"#aashima"
},
{"id":2,
"subject":"#aansh"
},
{"id":3,
"subject":"#artle"
}
]
}`
I tired to integrate the code with this json response, does Restangular supports this json and if it does do I need a different approach !!!
I'm trying to ng-repeat over 'cols' as a starting point. But I'm getting an error when trying to consume this JSON
{
"cols":["id","name","type"],
"rows":[
["284","JAMES DEAN","Employee"],
["243","Brian J Adamms","Employee"],
["237","Test Account","Brokerage Account"],
["241","Robert Borkman","guest"]
]
}
The error appears to be in the angularJS file, but Im sure the problem is elsewhere.

Here is a "plunker" example - run console - you'll see the same error I'm getting - and the JSON shows as an empty array.

Thank you all for help
I don't think the error is in angular source, and it will handle that JSON just fine: http://plnkr.co/edit/knJQ0S?p=preview
Im able to get what problem you are facing see the below code
<html ng-app="myapp" >
<head lang="en">
<meta charset="utf-8">
<title>Custom Plunker</title>
<script src="Scripts/Angular.js"></script>
</head>
<body >
<div ng-controller="TestCtrl" >
<div ng-repeat="data in data.cols">
{{data}}
</div>
</div>
<script>
var myapp = angular.module('myapp', []);
function TestCtrl($scope, $http,$timeout) {
$scope.data = {
"cols": ["id", "name", "type"],
"rows": [
["284", "JAMES DEAN", "Employee"],
["243", "Brian J Adamms", "Employee"],
["237", "Test Account", "Brokerage Account"],
