AngularJS - default value in selectbox - angularjs

I have a problem with default value in select element.
I have form for create new item and update from table.
Here is my code:
Controller:
function MyController($scope){
$scope.data = {};
$scope.selectedItem = null; //selected row from table
this.edit = function(){
$scope.enableEditation = true; // displayed editation form
$scope.data = $scope.selectedItem
}
}
HTML:
<select required ng-model="data.ID" class="form-control">
<option ng-repeat="option in types" value="{{option.ID}}" ng-selected="option.ID == data.ID">{{option.ID}} - {{option.NAME}}</option>
</select>
Default value is allways empty. Generated html in browser is:
<select class="form-control ng-pristine ng-untouched ng-valid ng-not-empty ng-valid-required" required="" ng-model="data.ID">
<option selected="selected" value="? number:4 ?"></option>
<option class="ng-binding ng-scope" value="4" ng-repeat="option in types" ng-selected="option.ID == data.ID">4 - First</option>
<option class="ng-binding ng-scope" value="12" ng-repeat="option in types" ng-selected="option.ID == data.ID">12 - Last</option>
</select>
Where can be problem? Thanks for advices.

Your problem is that your adding the value to the options trough
"value={{option.id}}"
This will always result in type conflict when your working with non-string values, since doing so will convert your id to a string, your simplest solution is to use "ng-value" instead and give it as reference:
"ng-value="option.id"

You just replace ng-selected="option.ID == data.ID" to ng-selected="data.ID"
<select required ng-model="data.ID" class="form-control">
<option ng-repeat="option in types" value="{{option.ID}}" ng-selected="data.ID">{{option.ID}} - {{option.NAME}}</option>
</select>
See the document https://docs.angularjs.org/api/ng/directive/ngSelected

Selected item Show In drop-down in Edit Case Angular JS

View Code Show the Drop Down In Client Side--
<select ng-model="employee.DeptId" class="form-control ng-pristine ng-invalid ng-invalid-required" required="">
<option disabled="disabled" value="">---Please Select---</option>
<option ng-repeat="Dep in ShowDep" value="{{Dep.Id}}">{{Dep.Name}}</option>
</select>
Angular Code In Edit Case----
$scope.EmployeeEdit = function (rowNumber) {
args = employeeArr[rowNumber];
$scope.employee.DeptId = args.DeptId;
}
Not clear about the structure of the data your binding.
So here I am showing your requirement with my own data. I think you could do the same in your cod also.
$scope.degrees = [
{"degree_code":"GB","degree_name":"Bachelor of Science"},
{"degree_code":"GR","degree_name":"Non Degree Undergraduate"}
];
$scope.selecteddegree = {degree_code:"GB"};
<!-- html -->
<select name="degree" class="form-control" ng-model="selecteddegree" ng-options="degree.degree_name for degree in degrees track by degree.degree_code" >
<option value=""> Select Degree </option>
</select>
Use ng-value instead of value in option tag.
<select ng-model="employee.DeptId" class="form-control ng-pristine ng-invalid ng-invalid-required" required="">
<option disabled="disabled" ng-value="">---Please Select---</option>
<option ng-repeat="Dep in ShowDep" ng-value="{{Dep.Id}}">{{Dep.Name}}</option>
</select>

How set default value as first value in angular select option

when am using this code.selected value shown as empty.i want select 1st value as one.
<select class="form-control" name="cityID" id="Select1" ng-change="RoomSelect()" ng-model="sRoom">
<option value="1" selected="selected">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
</select>
When am using ng-model at the time default value selected as empty.otherwise its ok.
Try init sRoom model in controller
$scope.sRoom = 1;
also its better use ng-options instead of repeat option in select tag.
Demo
var app = angular.module('anApp', []);
app.controller('aCtrl', function($scope) {
$scope.sRoom = 1;
$scope.chooses = [{"key":"one","value":1},{"key":"Two","value":2},{"key":"Three","value":3}];
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="anApp" ng-controller="aCtrl">
<select ng-change="RoomSelect()" ng-model="sRoom" ng-options="k.value as k.key for k in chooses">
</select>
</div>
Try this
<select class="form-control" ng-init="sRoom=1" name="cityID" id="Select1" ng-change="RoomSelect()" ng-model="sRoom">
<option value="1" selected="selected">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
</select>
You can also use ng-init
<select class="form-control" ng-init="sRoom=1" name="cityID" id="Select1" ng-change="RoomSelect()"

Preselect value in dropdown in Angular

I am trying to preselect a value in a dropdown/selectbox in Angular. It should be really simple, but it will not work.
This is my markup:
<select name="type" ng-model="ctrl.typeId" required>
<option value="1">Type 1</option>
<option value="2">Type 2</option>
<option value="3">Type 3</option>
<option value="4">Type 4</option>
</select>
In my controller i simply have:
vm.typeId = 2;
But it does not select anything. Instead, when using inspector on the dropdown element i see a new <option> with the value "? number:2 ?".
What am i missing?
Not need to ctrl in controller
$scope.typeId="2"
for selecting option with value 2
var app = angular.module("app",[]);
app.controller("ctrl" , function($scope){
$scope.typeId ='2';
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<select name="type" ng-model="typeId" required>
<option value="1">Type 1</option>
<option value="2">Type 2</option>
<option value="3">Type 3</option>
<option value="4">Type 4</option>
</select>
</div>
Select dropdown will give you a string so if you want to set something in dropdown you should initialize its model with a string value not number value.
Try this - vm.typeId = "2";

How to use ng-options in angular where Label and value are same

I am trying to create dropdown using ng-options, but at edit page its not working.
js file :
$scope.items = [
{name:"Angular"},
{name:"java script"},
{name:"Css3"},
{name:"Html5"},
];
$scope.name= "Css3";
html file :
<div class="form-group">Name</label>
<select class="form-control" ng-model="name" ng-options="a.name for a in items track by a.name" placeholder="Select Item"></select>
</div>
its working fine.
but I got selected value like this :
name:{
name:"selectedValue"
}
but I want like this :
name:"selectedValue"
in $scope.selected after selected value from dropdown.
and I referred this blog
after comparing #Satpal's demo and my output by inspect element and getting this :
my output
<select class="form-control ng-pristine ng-valid" ng-model="name" ng-options="a.name as a.name for a in items" placeholder="Select Item">
<option value="0" selected="selected" label="Angular">Angular</option>
<option value="1" label="java script">java script</option>
<option value="2" selected="selected" label="Css3">Css3</option>
<option value="3">Html5</option>
</select>
Satpal's output:
<select class="form-control ng-pristine ng-valid" ng-model="name" ng-options="a.name as a.name for a in items" placeholder="Select Item">
<option value="0">Angular</option>
<option value="1">java script</option>
<option value="2" selected="selected">Css3</option>
<option value="3">Html5</option>
</select>
Use the following expression of ngOption
select as label for value in array
Code
a.name as a.name for a in items

selected option into ng-repeat

I'm having the following script,
<select ng-model="create.Category" class="form-control input-sm" name="category" required>
<option value="" disabled="" selected="">Select Category</option>
<option ng-repeat="cat in categories" value="{{ cat.type }}">{{cat.type}}</option>
</select>
so my controller looks like this (categories is a factory which reaturn my categories to fill the select options, and info is an object instance with the parameters):
app.controller('myCtrl', function($scope, categories, info) {
$scope.categories = categories;
$scope.create = info;
});
so, my select options are filled perfectly, however, the ng-model="create.category" which has a value, is not been selected, it display the first category on the list.
Any guessing?
use ng-selected in select and compare the cat.type with value given
<select ng-model="create.Category" class="form-control input-sm" name="category" required>
<option value="" disabled="" selected="">Select Category</option>
<option
ng-selected="{{create.Category == cat.type}}"
ng-repeat="cat in categories" value="{{ cat.type }}">{{cat.type}}</option>
</select>
The preferred way is to use ngOptions :
