I have the dropdown as demonstrated below. All of this work. I just need to set default value for each one. I know how to do it for the upper level but how to do it for the next levels?
This is my html code:
<html ng-app="plunker">
<head>
<meta charset="utf-8" />
<title>AngularJS Plunker</title>
<script data-require="angular.js#1.2.x" src="https://code.angularjs.org/1.2.20/angular.js" data-semver="1.2.20"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl">
<div class="row">
<div class="col-md-4 col-xs-4 col-sm-4">
<select required ng-change="onBookChange(books,book)" ng-model="book" ng-options="bb.bookName for bb in books" class="form-control" >
<option value="">--Select--</option>
</select>
</div>
<div class="col-md-4 col-xs-4 col-sm-4">
<select required ng-model="chapter" ng-change="onChapterChange(books,chapter)" ng-options="cha.chapterName for cha in books.selectedChapters" class="form-control" >
<option value="">--Select--</option>
</select>
</div>
<div class="col-md-4 col-xs-4 col-sm-4">
<select required ng-model="title" ng-change="onTitleChange(books,title)" ng-options="t for t in books.selectedTitles" class="form-control" >
<option value="">--Select--</option>
</select>
</div>
</div>
</body>
</html>
and this is my javascript code:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.books=[
{
id:1,
bookName:'C++',
chapter:[
{chapterName:'Introduction',titles:['About Author','C++ Basic']},
{chapterName:'OOPS basic',titles:['Class','Object','Data Encapsulation','Inheritance','Interface']},
]
},
{
id:2,
bookName:'Java',
chapter:[
{chapterName:'Java Introduction',titles:['About Author','Java Intro']},
{chapterName:'Java basic',titles:['Variables','Function','Function Overloading','Class','Object']},
]
},
{
id:3,
bookName:'Angular JS',
chapter:[
{chapterName:'Introduction',titles:['MVC','Model','View','Controller']},
{chapterName:'Key Features',titles:['Template','Scope','Expressions','Filter','Controller','Module']},
]
}
];
$scope.onBookChange=function(b,book){
//alert("inside");
b.selectedChapters=book.chapter;
}
$scope.onChapterChange=function(b,cha){
//alert("inside");
// console.log(cha);
b.selectedChapter=cha;
b.selectedTitles=cha.titles;
}
$scope.onTitleChange=function(b,t){
// alert(t);
b.selectedTitle=t;
}
});
Please see demo below
var app = angular.module('app', ['ui.bootstrap']);
app.controller('homeCtrl', function($scope) {
$scope.books = [
{

you have your ng-models set to book, chapter, title. You just need to assign the default values to these on the scope
$scope.book = $scope.books[0];
//in the onBookChange function
$scope.chapter = book.chapter;
//in the onChapterChange function
$scope.title = cha.titles[0];

i have a dynamic form in angular. and i want to send the response as json. how do i generate JSON from the form?
here's the complete code,I have to get json, and post it to some api.
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>
<div ng-app="myApp" ng-controller="dyf" ng-submit="submit()">
<form name="userFormOne" novalidate>
<table>
<tr class="form-group" ng-repeat="x in names">

<script>
var app = angular.module('myApp', []);
app.controller('dyf', function($scope, $http) {

.then(function (response) {$scope.names = response.data;console.log(response.data);});
$scope.data ={};

In AngularJs we use ng-model to bind inputs value to our controller, sample:
This full sample to figure out how to create a simple form, from array and how to send it as JSON to your API.
Note: On submit check your console, and see the objects value.
var app = angular.module("app", []);
app.controller("ctrl",
function ($scope) {
var options = [
{ name: "a" },
{ name: "b" },
{ name: "c" }
];
$scope.names = [
{ id: 1, field: "insert name", name: "name", placeholder: "your name is", value:null, type:"text" },
{ id: 2, field: "insert phone", name: "phone", placeholder: "your phone is", value: null, type: "tel" },
{ id: 3, field: "insert age", name: "age", placeholder: "your age is", value: null, type: "number", min: 0, max: 20 },
{ id: 4, field: "select country", name: "country", placeholder: "your country is", value: null, type: "select", options: options }
];
$scope.sendMe = function() {
console.log($scope.names);
}
});

Hi I am developing angularjs application. I tried many ways to set default value for dropdown in Angularjs but I am not able to set default value.
<select ng-change="getModel(b.ID)" ng-model="b.ID" id="brand" ng-options="b.MakeName for b in list">
<option value="1">-- Select a Make --</option>//Not working
</select>
<select ng-change="getStyle(a.ID)" ng-model="a.ID" ng-options="a.ModelName for a in Modellist" id="make" >
<option value="1">-- Select a Model --</option>
</select>//Not working
<select ng-change="getallDetails(c.ID)" id="type" ng-model="c.ID" ng-options="c.BodyStayleName for c in ModelStyle">
<option value="1">-- Select a Type --</option>
</select>//Not working
May I know am i missing here anything? Any help would be appreciated. Thank you.
Use ng-init or set the default value to the model variable inside the controller,
$scope.BrandId = "1";
DEMO
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.5/angular.min.js"></script>
<script>
angular.module("myapp", [])
.controller("MyController", function($scope) {
$scope.register = {};
$scope.BrandId = "1";
$scope.brands = [{
id: "1",
name: "TOYOTA"
}, {
id: "2",
name: "HONDA"
}, {
id: "3",
name: "MARUTI"
}, {
id: "4",
name: "BMW"
}];
});
</script>
</head>
<body ng-app="myapp">
<div ng-controller="MyController">
<div>
<select ng-init="BrandId=='1'" ng-model="BrandId" ng-options="brand.id as brand.name for brand in brands"></select>
</div>

I am fetching data from API and I need a searchable dropdown so that when I start typing it shows me the data coming from the API. Currently I have this piece of code.
<select class="formControl" name="repeatSelect" id="repeatSelect" ng-model="facilitiesData.business_id">
<option ng-repeat="option in businesses" value="{{option.id}}">{{option.business_name}}</option>
</select>
Thanks.
Probably you are looking for this. This could be one of the solution.
This has different type of typeaheads. You can pick one as per your needs.
<input type="text" ng-model="customPopupSelected" placeholder="Custom popup template" uib-typeahead="state as state.name for state in statesWithFlags | filter:{name:$viewValue}" typeahead-popup-template-url="customPopupTemplate.html" class="form-control">
Note - You will require a library ui-bootstrap-tpls which is officially created by AngularJS team.
Try this. you cannot directly put textbox inside option and filter select based on it. but this is one way that you can don so. another way is to use plugin or angular material design.
// Angular
var myApp = angular.module('app', []);
myApp.controller('ListCtrl', function($scope) {
$scope.items = [{
'name': 'Item 1'
}, {
'name': 'Item 2'
}, {
'name': 'Account 3'
}, {
'name': 'Account 4'
}, {
'name': 'Item 5'
}, {
'name': 'Item 6'
}, {
'name': 'User 7'
}, {
'name': 'User 8'
}];
});
// jQuery
$('.dropdown-menu').find('.dontClose').click(function(e) {
e.stopPropagation();
});
.dropdown.dropdown-scroll .dropdown-menu {
max-height: 200px;
width: 60px;
overflow: auto;
}
.search-control {
padding: 5px 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
<link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<div class="dropdown dropdown-scroll" ng-app="app">
<button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown">Select <span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1" ng-controller="ListCtrl">
<li role="presentation" class="dontClose">
<div class="input-group input-group-sm search-control">
<span class="input-group-addon">
<span class="glyphicon glyphicon-search"></span>
</span>
<input type="text" class="form-control" placeholder="Query" ng-model="query"></input>
</div>
</li>
<li role="presentation" ng-repeat='item in items | filter:query'> {{item.name}}
</li>
</ul>
</div>
you can use datalist tag also If you want to build your own searchable dropdown ..Here is the working code:
HTML Part:
<html ng-app="app">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<div ng-controller="myCtrl">
<form ng-submit="click(search);">
<label class="child-label" for="existing-phases">Existing: </label>
<input type="text" ng-model="search" list="names">
<datalist id="names" class="form-control" ng-model="name">
<option value=''>-- select an option --</option>
<option ng-repeat="option in contacts | filter:search | limitTo:3" value="{{option.name}}"></option>
</datalist>
<button type="submit">Submit</button>
</form>
</div>
</body>
</html>
JS Part:
var app = angular.module('app', []);
app.controller('myCtrl', function($scope) {
$scope.showContacts = function() {
$scope.contacts = [{
id: 1,
name: "Ben",
age: 28
}, {
id: 2,
name: "Sally",
age: 24
}, {
id: 3,
name: "John",
age: 32
}, {
id: 4,
name: "Jane",
age: 40
}];
};
$scope.showContacts();
$scope.click = function(MyData) {
alert(JSON.stringify(MyData));
};
});
Working Demo is available here..https://plnkr.co/edit/hamW3F05YUPrWwS3RmmG?p=preview
You're in the right path. All you need to do now is create an http service or factory that triggers an API call every keypress, and the result of which populates your $scope.businesses array.
If you want to build searchable drop-down on your own then you can make use of filters.searchable drop-down with filters using textbox
If you want to go for a plugin check angular multi select
I've recenlty used in one of my projects. It is a flexible plugin and it allows multi-select also.
You can use dropdown select plugin
JS
const app = angular.module('DropdownSelectApp', ['DropDownSelect']);
HTML
<dropdown-select dd-model="exampleModel" dd-data="exampleItemList" dd-label="labelName" >
See this like for demo: https://saravanajd.github.io/Angularjs-Dropdown-Search/
I have a label that has class value based on 3 different conditions.
status = true => domain available
status =false=> domain not available
click => domain is selected
but when click on it, class should change to 'check-yes1'. How can i make it to change cssClass when clicked?
<div ng-repeat="(key,value) in newReg.checkedDomains | groupBy: 'domain'">
<label class="checkbox-inline" ng-class="{'check-yes' : ext.status==true}" ng-repeat="ext in value">
<input type="checkbox">
</label>
</div>
i even tried something like
<label class="checkbox-inline" ng-click="updateSelectStatus(ext.status,true)" ng-class="updateSelectStatus(ext.status,false)" ng-repeat="ext in value">
<input type="checkbox">
</label>
$scope.updateSelectStatus = function (status, selected) {
if (selected) {
return 'checked';
}
return status == 'true' ? 'check-yes' : '';
}
sorry to confuse with the mess :)
Full example:
<!doctype html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular.js"></script>
<style>
.check-yes {
background-color: green;
}
.available {
background-color: yellow;
}
.not-available {
background-color: red;
}
</style>
</head>
<body ng-app="plunker">
<div ng-controller="MainCtrl">
<div ng-repeat="(key,value) in newReg.checkedDomains">
<label class="checkbox-inline"
ng-class="{'check-yes': ext.available && ext.status,
'available': ext.available && !ext.status,
'not-available': !ext.available}"
ng-repeat="ext in value">
{{ext.name}} <input type="checkbox" ng-model="ext.status" ng-disabled="!ext.available">
</label>
</div>
</div>
<script>
var app = angular.module('plunker', []);
app.controller('MainCtrl', ['$scope', function($scope) {
$scope.newReg = {checkedDomains:
[
[{
status: true,
available: true,
name: 'com'
},{
status: false,
available: false,
name: 'org'
}],
[{
status: false,
available: true,
name: 'net'
},{
status: false,
available: true,
name: 'biz'
}]
]
};
}]);
</script>
</body>
</html>
Instead of binding to a function, use model.
<label class="checkbox-inline" ng-class="{'check-yes' : ext.status}" ng-repeat="ext in value">
<input type="checkbox" ng-model='ext.status'/>
</label>
I have the following code:

myApp.controller('myController',['$scope','$http',function ($scope,$http){
$http.get('js/data.json').success(function(data){
$scope.elevi = data;
$scope.eleviorder = 'name';
});
}]);
who get this data from data.json
[
{"name":"Udrea",
"prenume":"Alexandru",
"age":"27",
"highscool":"Henri Coanda",
"luckynumber":"7"
},
{"name":"Rizea",

{"name":"Ionescu",
"prenume":"Ema",
"age":"29",
"highscool":"Alexandru Lahovari",

]
My problem is that i can't orderby the luckynumber in natural order it orders the luckynumber like this 11,17,26,47,7,8 instead of 7,8,11,17,26,47
That's because angularjs consider this field as being a string property. So it is ordered in the alphabetical order. If you remove the quotes from the values of the integer properties, it should be working.
[
{"name":"Udrea",
"prenume":"Alexandru",
"age":27,
"highscool":"Henri Coanda",
"luckynumber":7
},
{"name":"Rizea",
"prenume":"Paul",
"age":23,
"highscool":"Mircea Cel Batran",
"luckynumber":11
