Getting the Current Value using angular ng-change? - angularjs

I am trying to get the user selected value from select list using ng-change, but i can't seem to find what went wrong:
Everytime i select any other option i get "Sam" , my question is how can i get the userselected value instead of the default one "Sam"
Here is the html:
<body ng-app="myApp" ng-controller="myCtrl">
<div>
<p> Employee Name/Employee ID:
<select ng-model="pickEmp" ng-change="setEmployee(pickEmp)">
<option ng-value="James">James</option>
<option ng-value="Sam">Sam</option>
<option ng-value="Patrick">Patrick</option>
</select>
</p>
</div>
</body>
and here is the JS
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope,$http) {
$scope.formObject = {
empId:'Sam',
que1:{
status:'YES',
payBand:0-11
}
$scope.setEmployee = function(){
$scope.pickEmp = $scope.formObject.empId;
}

Inside the setEmployee function, you are setting the ng-model as value sam. remove that line.
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope,$http) {
$scope.formObject = {
empId:'Sam',
que1:{
status:'YES',
payBand:0-11
}}
$scope.setEmployee = function(){
console.log($scope.pickEmp)
}
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="myApp" ng-controller="myCtrl">
<div>
<p> Employee Name/Employee ID:
<select ng-model="pickEmp" ng-change="setEmployee(pickEmp)">
<option ng-value="James">James</option>
<option ng-value="Sam">Sam</option>
<option ng-value="Patrick">Patrick</option>
</select>
</p>
</div>
</body>

Show filtered data with angular

I'm a very begginer in AngularJS(1.6) and I need to filter some results from a selected option.
I have to filter cities from states, and until there i'm doing fine. But then I need to filter and show the stores in this city on a list. Does anyone knows how to do It?
My code:
<!DOCTYPE html>
<html data-ng-app="myApp">
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.7/angular.min.js"></script>
</head>
<body data-ng-controller="testController">
<select id="state" ng-model="stateSrc" ng-options="state for (state, city) in states" ng-change="GetSelectedState()">
<option value=''>State</option>
</select>
<select id="city" ng-model="citySrc" ng-options="city for (city,store) in stateSrc" ng-change="GetSelectedCity()" ng-disabled="!stateSrc">
<option value=''>City</option>
</select>
<select id="city" ng-model="store" ng-options="store for store in citySrc" ng-disabled="!stateSrc || !citySrc">
<option value=''>Store</option>
</select>
<script>
angular
.module('myApp', [])
.run(function($rootScope) {
$rootScope.title = 'myTest Page';
})
.controller('testController', ['$scope', function($scope) {
$scope.states = {
'STATE_1': {
'City_1': ['Store_1', 'Store_2'],
'City_2': ['Store_3', 'Store_4']
},
'STATE-2': {
'City_3': ['Store_1', 'Store_2'],
'City_4': ['Store_3', 'Store_4']
}
};
$scope.GetSelectedState = function() {
$scope.strState = $scope.stateSrc;
};
$scope.GetSelectedCity = function() {
$scope.strCity = $scope.citySrc;
};
}
])
</script>
</body>
</html>
Thank's a lot!
It would be really helpful if you posted what your data source looks like. Assuming citySrc has objects containing arrays of stores, I would set a selectedCity in your controller when you call GetSelectedCity(), and then:
<ul>
<li ng-repeat="store in selectedCity.store">{{store}}</li>
</ul>
This will create list items for each store in your selectedCity object.

how to use indexof in array set in angularjs

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<script>
var app = angular.module('myApp', []);
app.controller('myctrl', function($scope) {
$scope.state = [{name:'TamilNadu', code:1}, {name:'Kerala', code:2}, {name:'Karnataka', code:3}];
$scope.onChange = function() {
var a = this.drop.state; }
});
</script>
<body>
<div ng-app="myApp" ng-controller="myctrl">
State :
<select id="stat" ng-model="drop.state" ng-change="onChange()">
<option ng-repeat = "x in state"> {{x.name}} </option>
<select>
</div>
</body>
In this code, I can be able to get the selected value from the textbox in the variable a. Now, I need to get the code value of the name selected. Is it possible using indexof(). And I need it in dynamic ie., when the 'state' is selected I need that corresponding 'code' from the array set.
<option value="{{x}}" ng-repeat = "x in state"> {{x.name}} </option>
If you add the value on your Option, you may get the complete object, and accessing the code and the Value
you can assign code as value to option
<option ng-repeat = "x in state" ng-value="x.code"> {{x.name}}
Demo
var app = angular.module('myApp', []);
app.controller('myctrl', function($scope) {
$scope.drop = {}
$scope.state = [{name:'TamilNadu', code:1}, {name:'Kerala', code:2}, {name:'Karnataka', code:3}];
$scope.onChange = function() {
var a = $scope.drop.state
console.log(a)
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myctrl">
State :
<select id="stat" ng-model="drop.state" ng-change="onChange()">
<option ng-repeat = "x in state" ng-value="x.code"> {{x.name}} </option>
</select>
</div>
Even though the other answer is valid, this is the right way to go about it:
<select id="stat" ng-model="drop.state" ng-options="x.code as x.name for x in state" ng-change="onChange()">
<option value="">Select a value</option>
</select>
If the purpose of the ng-change was to get the state code, this way it's not needed. Your ng-model will be equal to the selected state code.
You can bind data to a single property., and can access both. with preferred ng-options .
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<script>
var app = angular.module('myApp', []);
app.controller('myctrl', function($scope) {
$scope.state = [{
name: 'TamilNadu',
code: 1
}, {
name: 'Kerala',
code: 2
}, {
name: 'Karnataka',
code: 3
}];
$scope.onChange = function() {
alert(this.drop.state.name);
alert(this.drop.state.code);
}
});
</script>
<body>
<div ng-app="myApp" ng-controller="myctrl">
State :
<select id="stat" ng-model="drop.state" ng-options= "x as x.name for x in state" ng-change="onChange()"> </select>
</div>
</body>

How to use a select menu for user registration in AngularJS?

My current code:

<option value="doctor">Doctor</option>

I need 3 user types to be in the select menu and to pass the selected value to the database.
This might help you, I have listed two ways to achieve this, also have mentioned what value you should pass (I prefer passing id rather than name):

You need to use an angular controller with your view, like this.
var myApp = angular.module('myApp', []);
myApp.controller('MyController', ['$scope', function($scope){
$scope.user = {};
$scope.registerUser = function(){
alert($scope.user.userType);
};
}]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div ng-app="myApp">
<div ng-controller="MyController">
<select ng-model="user.userType" ng-required="true" class="form-control">
<option value="pharmacist">Pharmacist</option>
<option value="chief_pharmacist">Chief Pharmacist</option>
<option value="doctor">Doctor</option>
</select>
<button ng-click="registerUser()">register</button>
</div>
</div>

How to pass an object to the value property in option tag using angular?

I have a select tag which i have loaded the data through angular ng-repeat.
<select ng-model="user.accessRole">
<option ng-selected="{{item.name == user.accessRole.name}}"
ng-repeat="item in accessRoles" value="{{item}}">
{{item.name}}
</option>
</select>
Once I submit this the value I got for accessRole model is as below.
accessRole:"{"id":1,"name":"admin","accessRights":"administrative access"}"
I want this value to be passed without double quotes. That means,
accessRole:{"id":1,"name":"admin","accessRights":"administrative access"}
I tried out this by removing double quotes in value property.(value={{item}})
But it didn't give me the solution.
How can i do this?
It should be like to this.
var app = angular.module('anApp', []);
app.controller('ctrl', function($scope) {
$scope.user = {};
$scope.accessRoles= [{"id":1,"name":"admin","accessRights":"administrative access"}];
$scope.display = function(){
console.log($scope.user);
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.0/angular.min.js"></script>
<div ng-app="anApp" ng-controller="ctrl">
<div class="form-group">
<select ng-options="role as role.name for role in accessRoles" ng-model="user.accessRole" ng-change="display()">
</select>
</div>
</div>
use JSON.parse() to convert string to json object
angular.module("app",[])

$scope.submit = function(){
console.log($scope.user)
$scope.user.accessRole = JSON.parse( $scope.user.accessRole)
console.log($scope.user)
}
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<select ng-model="user.accessRole">
<option ng-repeat="item in accessRoles" value="{{item}}">
{{item.name}}
</option>
</select>
<button ng-click="submit()">click</button>
</div>

Add this in the controller after defining your $scope.countries
$scope.state1 = Object.keys($scope.countries)[0];
Remove ng-init from Html page.
