I do have a working table using JSON and angular, I set up my $http header to get the Json in the particular .api, I run it but nothings appear in getting my Json file in the $Http.get, I would like to ask if this is a valid header, I mean is there something wrong with my delimeter?
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-rc.0/angular.min.js"></script>
<script type="text/javascript">
var myTable=angular.module('myTable',[]);
myTable.controller('tableCtrl',function($scope,$http){
$http.get ("http://staging.api.sample.com/events.json", {header: {Authorization: 'vsdnmsndjednmsdnjemsdjendmsdnjeNmJHMN'}}); .success(function(response) {
debugger
$scope.members=response.events;
$scope.totals = response.paging;
});
});
Remember about correct style guide. It should help you. Also check this link https://github.com/johnpapa/angular-styleguide/
(function {
'use strict';
angular
.module('myTable', [])
.controller('tableCtrl', tableCtrl);
tableCtrl.$inject = ['$scope', '$http'];
function tableCtrl($scope, $http) {
$http.get("http://staging.api.sample.com/events.json", {
header: {
Authorization: 'vsdnmsndjednmsdnjemsdjendmsdnjeNmJHMN'
}
}).then(function(response.data) {
$scope.members = response.data.events;
$scope.totals = response.data.paging;
}).catch(function(error) {
});
});
}());
This query is wrong:
$http.get("http://staging.api.sample.com/events.json", {
header: {
Authorization: 'vsdnmsndjednmsdnjemsdjendmsdnjeNmJHMN'
}
}
You can pass parametes by get building query like this one:
$http.get("http://staging.api.sample.com/customer/1") or
$http.get("http://staging.api.sample.com/customer/" + some_param). If you would like to send some object to you API you should use POST. For example:
$http.post("http://staging.api.sample.com/events.json", {object});

I'm coding a mobile application with ionic. I have to get a data (daily changing data) from a web page with JSON, but I want to get old data too. For example:
data.json?date=2016-11-10
data.json?data=2016-12-10
How can I send request to JSON?
To send data from PHP, once you get your data from the database, the array will apply json_encode($array); and to return you put return json_encode ($ array);
Try this!
var date = '2016-11-10';
$http({
method: 'GET',
url: data.php,
params: {date: date},
dataType: "json",
contentType: "application/json"
}).then(function(response) {
});
The question is confusing, so I'm not sure how to answer. If you are having trouble formatting a request to a REST service, you will need to find out how the service expects the date to be formatted in your field-value pair i.e:
date=2016/11/10 or date=20161110
If those don't work, this answer may help The "right" JSON date format
However, if you are actually wondering how to serialize a date in JSON, this link may help http://www.newtonsoft.com/json/help/html/datesinjson.htm
I prefer to use services for ajax requests.
Create a Service
//Service
(function() {
'use strict';
angular
.module('appName')
.factory('appAjaxSvc', appAjaxSvc);
appAjaxSvc.$inject = ['$http', '$log', '$q'];
/* #ngInject */
function appAjaxSvc($http, $log, $q) {
return {
getData:function (date){
//Create a promise using promise library
var deferred = $q.defer();
$http({
method: 'GET',
url:'/url?date='+date
}).
success(function(data, status, headers,config){
deferred.resolve(data);
}).
error(function(data, status, headers,config){
deferred.reject(status);
});
return deferred.promise;
},
};
}
})();
Then Use it in Controller
(function() {
angular
.module('appName')
.controller('appCtrl', appCtrl);
appCtrl.$inject = ['$scope', '$stateParams', 'appAjaxSvc'];
/* #ngInject */
function appCtrl($scope, $stateParams, appAjaxSvc) {
var vm = this;
vm.title = 'appCtrl';
activate();
////////////////
function activate() {
appAjaxSvc.getData(date).then(function(response) {
//do something
}, function(error) {
alert(error)
});
}
}
})();
I am new to angular and I am trying to load a CSV list inside a factory and then convert it to json. I am using Papaparse (CSV to json library) inside the factory. When I console log the factory I get the array of objects which is exactly what I want but when I pass it inside my controller I get a single object which holds all the data.
This is my factory
(function() {
var app = angular.module('test');
app.factory('testFactory', ['$http', function($http) {
var url = 'my-list.csv';
var getContact = function() {
return $http.get(url).success(function(data) {
Papa.parse(data, {
header: true,
complete: function(results) {
console.log(results.data);
return results.data;
}
});
});
};
return {
getContact: getContact
};
}]);
}());
And this is my controller
(function() {
var app = angular.module('test');
app.controller('testCtrl', ['$scope', 'testFactory', function($scope, testFactory) {
testFactory.getContact().then(function(data) {
$scope.contacts = data;
console.log(data);
});
}]);
}());
I want be able to do something like this inside my view
{{ contact.firstname }}
The issue is the order of resolution. Inspecting the console statements shows that you're assigning $scope.contacts to the resolution of the $http.get promise, and not the actual parsing.
Instead of returning the $http.get promise, return a deferred promise and resolve at the end of parsing:
var parsePromise = $q.defer();
$http.get(url).success(function(data) {
Papa.parse(data, {
header: true,
complete: function(results) {
console.log(results.data);
parsePromise.resolve(results.data);
}
});
});
return parsePromise.promise;
See working demo here.
Update: As per the comments, you could use .then to chain promises instead of creating a new deferred. The plunkr has both, you can use the changelog to toggle methods.
I am trying to create a website in where I can get a particular json object from a url and then display it on the website. The field that I am trying to display is UV_INDEX out of three fields. Nothing is being printed out. I don't even know if it is getting the json object.
<!DOCTYPE html>
<html>
<body>
<h2>EPA </h2>
<p id="demo"></p>
<script>
var getJSON = function(url) {
return new Promise(function(resolve, reject) {
var xhr = new XMLHttpRequest();
xhr.open('get', url, true);
xhr.responseType = 'json';
xhr.onload = function() {
var status = xhr.status;
if (status == 200) {
resolve(xhr.response);
} else {
reject(status);
}
};
xhr.send();
});
};
getJSON('http://iaspub.epa.gov/enviro/efservice/getEnvirofactsUVDAILY/ZIP/92507/JSON').then(function(data) {
document.getElementById('UV_INDEX').innerHtml=json.result;
alert('Your Json result is: ' + json.result); //you can comment this, i used it to debug
result.innerText = data.result; //display the result in an HTML element
}, function(status) { //error detection....
alert('Something went wrong.');
});

I added a third-party chrome extenstion for CORS issue. But I get this error
Uncaught (in promise) ReferenceError: json is not definedmessage: "json is not defined"stack: (...)get stack: function () { [native code] }set stack: function () { [native code] }__proto__: Error
You can try using a Ajax plugin to make CORS request where the CORS headers are not being served from service.
Add Jquery library and add your installed CORS ajax scripts after that:
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
<script type="text/javascript" src="js/jquery.ajax-cross-origin.min.js"></script>
Now you can make cross origin request by just adding crossOrigin: true in your Ajax:
E.g.
$.ajax({
crossOrigin: true,
url: "http://iaspub.epa.gov/enviro/efservice/getEnvirofactsUVDAILY/ZIP/92507/JSON/",
success: function(data) {
console.log(data);
}
});
You can try putting the same URL in the below demo page to receive the Json data.
See live demo.
i'm building application which uses CORS requests. Each request i use get host address from a constant
angular.module('siteApp').constant('baseUrl', {
'server':'htttp://localhost/',
})
And in each service i use to send request like this:
angular.module('siteApp').factory('DocsSvc', function ($http, baseUrl) {
var baseurl = baseUrl.server ;
$http.get(baseurl + 'document')
Is it possible to make 'htttp://localhost/' value - to came from config.json file into baseUrl constant or baseUrl factory?
I mean : how can i load something from ajax request an make it accessible to app modules
i have tried:
.run(['$rootScope', , function ($rootScope) {
$.ajax('config.json', {async: false})
.success(function (data) {
$rootScope.HOST = data.HOST;
});
And tried to access it from baseUrl:
angular.module('siteApp').factory('baseUrl',function($rootScope) {
return {
server: $rootScope.HOST
But no luck - the baseUrl.server comes undefined into functions
You can use run method of angular.
var app = angular.module('plunker', []);
app.run(function($http, $rootScope){
$http.get('config.json')
.success(function(data, status, headers, config) {
$rootScope.config = data;
$rootScope.$broadcast('config-loaded');
})
.error(function(data, status, headers, config) {
// log error
alert('error');
});
})
app.controller('MainCtrl', function($scope, $rootScope) {
$scope.$on('config-loaded', function(){
$scope.name = $rootScope.config.name;
});
});
see this plunker
If you want to do it even before the angular app starts, you can, instead of using the ng-app directive, use the bootstrap function.
From:
https://docs.angularjs.org/api/ng/function/angular.bootstrap
<!doctype html>
<html>
<body>
<div ng-controller="WelcomeController">
{{greeting}}
</div>
<script src="angular.js"></script>
<script>
var app = angular.module('demo', [])
.controller('WelcomeController', function($scope) {
$scope.greeting = 'Welcome!';
});
// Do your loading of JSON here
angular.bootstrap(document, ['demo']);
</script>
</body>
</html>
You need to tell angular about data change, so modify your code something like this:
.run(['$rootScope', function ($rootScope) {
$.ajax('config.json', {async: false})
.success(function (data) {
$rootScope.HOST = data.HOST;
$rootScope.$apply(); // New line
});
}])
That $apply() is needed since its a non-angular asynchronous call.
use the blow code snippet to load the json values
.run(function ($http, $rootScope) {
$http.get('launchSettings.json')
.success(function (data, status, headers, config) {
$rootScope.config = data;
$rootScope.$broadcast('config-loaded');
})
.error(function (data, status, headers, config) {
// log error
alert('error');
});
});
I have the following code to present data from a link (API) as suggestion for an autocomplete box. Although it is working for one link and not the other. I observed that data format for both are different, modified my code accordingly but it is still not helpful.
.js file:
var plunker= angular.module('plunker', ['ui.bootstrap', 'ngGrid']);
function TypeaheadCtrl($scope, $window, $http, limitToFilter) {
$scope.cities = function (cityName) {
return $http.jsonp("http://mtapi.azurewebsites.net/api/institute").then(function (response) {
return response[0].description;
});
};
}
HTML file:
<input type="text" id="depn" ng-model="formdata.department"
typeahead="suggestion.description for suggestion in cities($viewValue)"
placeholder="department" class="form-control">
If you replace the cities function with this one,
$scope.cities = function (cityName) {
return $http.jsonp("http://gd.geobytes.com/AutoCompleteCity?callback=JSON_CALLBACK &filter=US&q=" + cityName).then(function (response) {
return response.data;
});
};``
Even after I changed my code jsonP request to .get, it is still not working
var plunker= angular.module('plunker', ['ui.bootstrap', 'ngGrid']);
function TypeaheadCtrl($scope, $window, $http, limitToFilter) {
$scope.cities = function (cityName) {
return $http.get("http://mtapi.azurewebsites.net/api/institute").success(function(data) {
return data[0].description;
});
};
}
It is working fine.
Is there a problem with my code, or a back end server issue?
Change your cities function to use the data property of the response in your .then (that's how you'll access the response from a resolved HttpPromise):
var plunker= angular.module('plunker', ['ui.bootstrap', 'ngGrid']);
function TypeaheadCtrl($scope, $window, $http, limitToFilter) {
$scope.cities = function (cityName) {
return $http.get("http://mtapi.azurewebsites.net/api/institute").then(function (response) {
return response.data[0].description;
});
};
EDIT
Even making that code change won't solve your problem. This url does not support cross-origin requests, so you either need to host your angularjs app on the same domain and use a plain $http.get instead of $http.jsonp, or this url needs to support JSONP requests (the content-type of the response from this url is application/json. For JSONP to work it should be application/javascript).
I figured it out lately. Apart from the problem at back end there were issues in this code as well. I was returning the promise, but promise was never resolved to return the value also I was trying to return a string, whereas I should return array of strings. Here's the change:
$scope.aap = result.data;
var res = [];
res.push($scope.aap[0].Description);
return res;
