Question

I want to use a user input value in to controller. for example i want to take a URL and send a HTTP GET request. I have tried the following format , unfortunatly it does not work.

<script>
var app = angular.module('myApp',[]);
app.controller('myCtrl' , function($scope, $http){
$http.get("{{url}}")
.success(function(response){
$scope.data=response.data;
});
});
</script>

Answer 1

Here is the url retrieved from a user's input

 var app = angular.module('myApp', []); app.controller('myCtrl', function($scope, $http) { $scope.callAPI = function() { console.log($scope.url); $http.get($scope.url) .success(function(response) { $scope.result = response.data; }); }; }); 

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <div ng-app="myApp" ng-controller="myCtrl"> Enter url : <input type="text" ng-model="url" /> <input type="submit" ng-click="callAPI()" /> <div ng-bind="result"></div> </div> 

Note : This will show an error if you entered a wrong url

Answer 2

There should be loyout like this:

<input ng-model="url" required/>

then you can use

$http.get($scope.url)....
