I am trying to write a webapp that will retrieve a set of orders from a backend database, display each order to the user one by one allowing update before moving on to the next order.
Is this feasible using purely AngularJS or would I need to contemplate jQuery as well? I can display all the orders in an ng-repeat but I would rather only display them one at a time.
EDIT
The PHP below will return a number of records in the form
[{round:1, name:"Mr Smith", house:22, road:"The Street", year:2013, period:10, result:"O", amount:20}...]
to the controller NewOrderCtrl.
What I would like to know is how to loop through each record retrieved, display the data in the ng-view so that it can be updated, submit and the next record displayed.
JS
var orderApp = angular.module('orderApp',['ngRoute']);
orderApp.config(function($routeProvider,$locationProvider) {
$locationProvider.html5Mode(true);
$routeProvider
.when("/neworder", {templateUrl: "partials/neworder.html", controller:"NewOrderCtrl"})
.otherwise({redirectTo: '/'});
});
function NewOrderCtrl($scope,$http) {
$http.get('php/get_orders.php')
.success(function(data) {
$scope.order = data;
});
};
PHP
<?php
include 'conn.php';
$rs = mysql_query("SELECT d.id,
d.number AS round,
c.name,
c.house,
c.road,
o.year,
o.period,
o.result,
o.amount
FROM tbldrop d
LEFT JOIN vwcustomer c
ON d.customer = c.id
LEFT JOIN tblorder o
ON d.customer = o.customer
WHERE d.number > 0
ORDER BY d.number, d.position");
$items = array();
while($row = mysql_fetch_object($rs)){
$items[] = $row;
}
echo json_encode($items);
?>
neworder.html (currently displays all records retrieved)
<div ng-controller="NewOrderCtrl">
<div ng-repeat="customer in order">
<div>
<span ng-bind="customer.name"></span><br/>
<span ng-bind="customer.house"></span>
<span ng-bind="customer.road"></span><br/>
</div>
<form role="form">
<div class="form-group">
<label for="result" class="control-label">Result:</label>
<div>
<input type="text" ng-model="customer.result" placeholder="Enter result">
</div>
</div>
<div class="form-group">
<label for="amount" class="control-label">Amount:</label>
<div>
<input type="text" ng-model="customer.amount" placeholder="Enter amount">

In order to give a complete answer, we would need some code samples or even a jsfiddle to play with, but as a generic answer, yes this is entirely possible with only angularjs.
With the extremely limited amount of information I have, I would suggest doing something like this:
Controller:
$scope.items = [];
$http({method: 'GET', url: '/someUrl'}).success(function(data) {
$scope.items = data;
});
$scope.itemIndex = 0;
$scope.nextItem = function() {
if ($scope.items[$scope.itemIndex + 1]) {
$scope.itemIndex++;
}
};
HTML:
{{ items[itemIndex] }}
<button ng-click="nextItem()">Next</button>
Here's a JSFiddle using $timeout instead of $http to simulate the server response time: http://jsfiddle.net/Z5chE/

Having issues getting a simple filter to work for an album selection app i'm building for experience using jsonplaceholderdata. I tried to set ng-model to an expression and filtering by that expression but nothing changes when i enter text into my input bar. Unsure as to what I'm missing.

This is my angular js code:
var app = angular.module('myApp', []);
app.controller('AlbumCtrl', function ($scope, $http) {
$http.get("http://jsonplaceholder.typicode.com/albums").then(function(response) {
$scope.albumData = response.data;
console.log($scope.albumData);
});
});
app.controller('PhotoCtrl', function($scope, $http) {
$http.get("http://jsonplaceholder.typicode.com/photos").then(function(response) {
$scope.photoData = response.data;
// console.log($scope.photoData);
});
});
Any help is much appreciated.
You don't need to use a controller function. Because your q is already on the $scope, it will work as soon as you start typing in the input box.
Your controller is outside of the scope of the 'q' scope variable though.
var app = angular.module("app", []);
app.controller('emp', ['$scope', 'empService', function($scope, empService){
$scope.doSearch = function(){
empService.findEmployeeById($scope.searchempno, function(r){
$scope.empno = r.empno;
$scope.ename = r.ename;
$scope.salary = r.salary;
$scope.dptno = r.dptno;
});
};
}]);
app.service('empService', ['$http', '$log', function($http, $log){
this.findEmployeeById = function(empno, cb){
$http({
url: 'employees.json' + empno,
method: 'GET'
}).then(function(resp){
cb(resp.data);
});
};
}]);

If I gave the number in input field like 1001 and click the search button. It will not show the details. I have checked the console, there is no error. My JSON file has been placed the same location of the HTML file.
Thanks,
SamBhishma
I have created an updated plunker here. First issue was what I mentioned in the comment. In your view, you are writing <input type="text" class="form-control" ng-model="searchEmpno"/>and in your controller, you're trying to access this variable as searchempno
Second issue is in your http request. You cannot pick and choose the data from json file based on the id. You have to get the entire JSON file, parse it and filter out the value if it matches your searchEmpno model value. I fixed it in the plunker.
Third issue, you are attaching plain values to your scope like $scope.empno , $scope.ename. Instead, you need to put such values into an object, so in your controller, put the matched employee object in the scope and in your view, reference it as {{obj.ename}} and so on.
Another thing, no need to return callbacks inside then. The clean way of handling successful, failed http calls is:
$http.get('url').then(function successCallback(response) {
// this callback will be called asynchronously
// when the response is available
}, function errorCallback(response) {
// called asynchronously if an error occurs
// or server returns response with an error status.
});
Read more about them here.
Take a look at the updated plunker to see if it matches your needs.
Problem is your model variable is wrong inside the view, try this
<input type="text" class="form-control" ng-model="searchEmpno"/>

I have been having this issue with Controllers in Angular. I looked it up as much as possible, but I could not resolve the issue.
I am trying to implement a simple controller, but for the life of me, I cannot get the binding to work. It's not displaying my data. For example when I say, {{ test }}, I get just that, not the "Hello World!" string.
var app = angular.module('App', []);
app.controller('Hi', function($scope){
$scope.hello = "hello!";
});
app.controller('todoCtrl', ['$scope', '$http', function($scope, $http) {
$scope.test = "Hello World!";
$scope.formData = "";
$http.get('/api/todos')
.success(function(data) {
$scope.todos = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
$scope.createTodo = function() {
$http.post('/api/todos', $scope.formData)
.success(function(data) {
$scope.formData.text = "";
$scope.todos = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
};
$scope.deleteTodo = function(id) {
$http.delete('/api/todos/' + id)
.success(function(data) {
$scope.todos = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
};
}]);

I just executed your code while placing angular file link above the script tag, so that AngularJs is loaded before your script can call angular modules.
I think you're putting angular after your script which is why you are running into this issue. Your code works just fine. I tested it.
Put it like this
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.7/angular.min.js"></script>
<script src="script.js"></script>
Here script.js will be your controller script.

You are specifying loginController in your html as well as in your route configuration. I'm not certain that this is the cause of the problem, but doing both is unnecessary. Remove one of them.
In other words, eliminate controller: 'loginController' from below
$stateProvider
.state('login',{
url:'/login',
templateUrl:'view/login.html',
controller:'loginController'
});
or eliminate: ng-controller="loginController" from:
<div ng-controller="loginController" class="col-xs-12 col-sm-6 col-md-4 center-block" id="lgBlock">
Also, unrelated, but I doubt that these two lines:
$scope.userName = angular.element('#usrName').val();
$scope.password = angular.element('#pass').val();
do what you think. The purpose of angular.element is to wrap elements as jquery elements. I suspect you want to use document.getElementById here to get references to the items. However, you're using ngModel here, so none of this should be necessary if you use consistent spelling. (In one place you have userName and in another usrName.)
issue was wrong spelling of adapter
/* wrong one */
$scope.loginProcedure ={
procedure:'login',
adaptor:'SQL',
parameters:[$scope.userName, $scope.password]
};
/*write one */
$scope.loginProcedure ={
procedure:'login',
adapter:'SQL',
parameters:[$scope.userName, $scope.password]
};
I'm new to AngularJS and am trying to use it to link up with a simple web API I have in place. I already have URLs that return JSON data in the format: http://127.0.0.1:8000/posts/ followed by a date in the format YYYY-MM-DD. (example would be http://127.0.0.1:8000/posts/2015-07-28)
I have an input text box which I want to use to get the JSON data from my API and list it out, meaning if I enter 2015-07-28 into the input box, it should pull the JSON data from the API appropriately without a page refresh by appending the string value from the input box onto whatever URL I want (in this case that would be http://127.0.0.1:8000/posts/).
Here is what I have as of right now:

Use ng-change or watch your model. Depending on your input you may want to use the debounce in ng-model-options.
var ListingApp = angular.module('ListingApp', []);
ListingApp.controller('PostCtrl', function($scope, $http) {
$scope.select = "";
var postJSON = "http://127.0.0.1:8000/posts/" + $scope.select;
console.log(postJSON);
function getPost() {
$http.get(postJSON)
.then(function(res) {
$scope.posts = res.data;
console.log($scope);
});
}
// option #1 with ng-change="change()"
$scope.change = function() {
getPost();
}
// option #2 with watch
$scope.$watch('select', function (val, old) {
console.log(val);
getPost();
});
