how to populate select option in angular - angularjs

I have a dynamically created data. Based on this I am creating a form. But problem is option is not added to to the select. What is wrong in this.
customerB :
{
rows:3,
columns: 2,
name: 'customerB',
fields:
[
{type: "select", name:"teacher_id", label: "Teacher" , endpoint: "/teachers", required: true, check:[ { id : "1982", name : "Mr Bob"}, { id : "18273", name : "Mrs Katrine"} ]}
],
}
HTML
<div class="rows" ng-repeat="field in customerB">
<div class="columns" ng-repeat="newvalue in field">
<div class="controls" ng-switch="newvalue.type">
<div class="form-group">
<label class="control-label">{{newvalue.label}}</label>
<select class="form-control" ng-switch-when="select" ng-model="hiii" ng-required="newvalue.required" ng-options="item.id as item.name for item in newvalue.check">
</select>
</div>
</div>
</div>
</div>

You got an object which got an array, inside the array you got another array which is not correctly manipulating.
Try understanding the following code snippet:
HTML:
<select name="repeatSelect" id="repeatSelect">
<option ng-repeat="option in data.availableOptions" value="{{option.id}}">{{option.name}}</option>
</select>
JS
availableOptions: [
{id: '1', name: 'Option A'},
{id: '2', name: 'Option B'},
{id: '3', name: 'Option C'}
]
OR follow the link: https://docs.angularjs.org/api/ng/directive/select

This assumption might be wrong but I think in here ng-repeat="field in customerB" you are accessing object property directly without the scope variable. So you need to add whatever the scope variable name in front of the property name.
<div class="rows" ng-repeat="field in obj.customerB">
Other than that code you provided work perfectly.
Demo
angular.module("app",[])
.controller("ctrl",function($scope){
$scope.obj = { customerB :
{
rows:3,
columns: 2,
name: 'customerB',
fields:
[
{type: "select", name:"teacher_id", label: "Teacher" , endpoint: "/teachers", required: true, check:[ { id : "1982", name : "Mr Bob"}, { id : "18273", name : "Mrs Katrine"} ]}
],
}}
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<div class="rows" ng-repeat="field in obj.customerB">
<div class="columns" ng-repeat="newvalue in field">
<div class="controls" ng-switch="newvalue.type">
<div class="form-group"> <label class="control-label">{{newvalue.label}}</label> <select class="form-control" ng-switch-when="select" ng-model="hiii" ng-required="newvalue.required" ng-options="item.id as item.name for item in newvalue.check"></select> </div>
</div>
</div>
</div>
</div>

Adding the input fields dynamically from nested json object in angulajs

var inputs={
'firstname': '',
'lastName':'',
'account':{
'role':'',
'status':''
}
}
This is my model array. I want to display it dynamically in Webpage and by modifying the json array the changes should affect the form too.
Here is the image
UPD:
for your situation, you can use ng-switch to generate elements according to conditions.
Notice(already included in the code snippet):
ng-repeat will generate it's own scope, so your model won't update unless you bind it with the original scope. ref here.
OLD ANSWER:
use ng-model to implement two-way-databinding.
refer the code snippet below:
angular.module("app", []).controller("myCtrl", function($scope) {
$scope.inputs = {
'firstname': 'test first name',
'lastName': 'test last name',
'account': {
'role': 'test role',
'status': 'test status'
}
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.4/angular.min.js"></script>
<div ng-app="app" ng-controller="myCtrl">
<!-- First Name: <input type="text" ng-model="inputs.firstname"><br>
Last Name: <input type="text" ng-model="inputs.lastName"><br> Account Role: <input type="text" ng-model="inputs.account.role"><br>
Account Status: <input type="text" ng-model="inputs.account.status"><br> -->
<div ng-repeat="(key1, value) in inputs" ng-switch="key1">
<div ng-switch-when="account">
<div ng-repeat="(key2, value2) in value">
{{key1 | uppercase}} => {{ key2 | uppercase}}
<input type="text" ng-model="inputs[key1][key2]">
</div>
</div>
<div ng-switch-default>
{{key1 | uppercase}}
<input type="text" ng-model="inputs[key1]">
</div>
</div>
{{inputs}}
</div>
/My html should look like this/
<head>
<script data-require="angular.js#1.4.1" data-semver="1.4.1" src="https://code.angularjs.org/1.4.1/angular.js"></script>
<script src="script.js"></script>
</head>
<body ng-controller="MainCtrl">
<script type="text/ng-template" id="tree-structure">
<label>{{dt}}</label><input type="text" name="" value="{{dt.label}}">
<ul class="childElement">
<li ng-repeat="dt in dt.nodes" ng-include="'tree-structure'">
</li>
</ul>
</script>
<ul class="parentList">
<li ng-repeat="(key, value) in inputs" >
<div ng-repeat="(key1, value1) in value">
<label>{{key1}}</label>
<input type="text" name="" value="{{value1}}">
<!-- <div ng-repeat="(key2, value2) in value1">
<label>{{key2}}</label><input type="text" name="" value="{{value2}}">
</div> -->
</div>
<div ></div>
</li>
</div>
</ul>
</body>
</html>
Some observations :
Your JSON should be formatted properly with type of the field.
If you want to access the object properties as a form fields then it should be structured in a good way so that we can dynamically add the type of the field as well.
[{
name: 'firstName',
type: 'text'
}, {
name: 'lastname',
type: 'text'
}, {
account: [{
name: 'role',
type: 'text'
}, {
name: 'status',
type: 'text'
}]
}]
As your JSON have nested objects. So, first iterate it recursively and create one dimensional array then create the fields using 1D array.
DEMO
var myApp = angular.module('myApp',[]);
myApp.controller('MyCtrl', function($scope) {
var inputs = [{
name: 'firstName',
type: 'text'
}, {
name: 'lastname',
type: 'text'
}, {
account: [{
name: 'role',
type: 'text'
}, {
name: 'status',
type: 'text'
}]
}];
$scope.fields = [];
function structuredObj(obj) {
for (var i in obj) {
if (obj[i].type == 'text') {
$scope.fields.push(obj[i]);
} else {
structuredObj(obj[i])
}
}
};
structuredObj(inputs);
});

Select value not selected in Angularjs

I have this html markup:
<div ng-repeat="prop in props" style="margin-bottom: 10px;">
<label class="col-md-4 control-label">Property {{$index + 1}} ({{prop.AddressLine1}})</label><div class="col-md-8">
<select ng-model="prop.Grade" class="form-control" ng-options="opt.name for opt in propGradings track by opt.id"> <option ng-selected="{{option.id == prop.Grade}}" ng-repeat="option in propGradings" ng-value="{{option.id}}">{{option.name}}</option> </select>
</div>
</div>
This static array to fill in the dropdown:
$scope.propGradings = [{ name: "1", id: 1 }, { name: "2", id: 2 }, { name: "3", id: 3 }, { name: "4", id: 4 }];
I'm able to load the items in the dropdown, but I'm not able to preselect the correct value based on the prop.Grade value.
HTML Output:
Any idea what am I doing wrong?
When selecting options from a dropdown, type matters for binding purposes. When using ng-options, you can use as to bind something to the model as a non-string value. In your case, you may want to bind to the integer value of the id.
Syntax: select as label for value in array
> select: The value that gets bound to ng-model
> label: What value visibly shows up in the dropdown
> value: Current item in array
> array: Data source for generating the options
Example of binding to an integer value:
var app = angular.module("myApp", []);
app.controller("myCtrl", function ($scope) {
$scope.props = [{Grade: 1}];
$scope.propGradings = [{ name: "1", id: 1 }, { name: "2", id: 2 }, { name: "3", id: 3 }, { name: "4", id: 4 }];
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
Binding with an integer value:
<div ng-repeat="prop in props" style="margin-bottom: 10px;">
<label class="col-md-4 control-label">Property {{$index + 1}} ({{prop.AddressLine1}})</label>
<div class="col-md-8">
<select ng-model="prop.Grade" class="form-control" ng-options="opt.id as opt.name for opt in propGradings">
<option ng-selected="{{option.id == prop.Grade}}" ng-repeat="option in propGradings" ng-value="{{option.id}}">{{option.name}}</option>
</select>
</div>
</div>
</div>
Example of binding to a string value:
var app = angular.module("myApp", []);
app.controller("myCtrl", function ($scope) {
$scope.props = [{Grade: "1"}];
$scope.propGradings = [{ name: "1", id: 1 }, { name: "2", id: 2 }, { name: "3", id: 3 }, { name: "4", id: 4 }];
});

HTML form is not generated in angular scope

I am trying to generate a HTML form with angularjs ngRepeat. I load a JSON file that contains the fields of desired form and save this object in my $scope. I have a ngRepeat element that generates form inputs based on the JSON object.
The problem is when I print $scope.<myFormName> it just have one field name "{{header.name}}" as I expect some fields based on my JSON model.
Actually I see the form generated in HTML properly but the same thing does not happen in angular scope.
angular.module("myApp",[])
.controller("myCtrl",["$scope",function($scope){
// In this funtion I Set fields of form and make my model empty
$scope.getHeaders = function () {
console.info('getHeaders');
$scope.headersForCreation = [
{
name: 'givenName',
type: 'string',
caption: "nameAndFamily"
},
{
name: 'userName',
type: 'string',
caption: "userName"
},
{
name: 'password',
type: 'password',
caption: "password"
},
{
name: 'passwordConfirm',
type: 'password',
caption: "passwordConfirm"
},
{
name: 'mail',
type: 'string',
caption: "email"
},
{
name: 'mobile',
type: 'string',
caption: "mobile",
regex: '0[1-9][0-9]{9}'
}
];
$scope.userInputsInCreation = {};
angular.forEach($scope.headersForCreation, function (headerItem, key) {
$scope.userInputsInCreation[headerItem.name] = '';
});
}; // end of get header
$scope.getHeaders();
console.log($scope.createForm)

Because your controller initialized before AngularJS form directive.
angular.module("myApp",[])
.controller("myCtrl",["$scope","$timeout",function($scope, $timeout){
// In this funtion I Set fields of form and make my model empty
$scope.getHeaders = function () {
console.info('getHeaders');
$scope.headersForCreation = [
{
name: 'givenName',
type: 'string',
caption: "nameAndFamily"
},
{
name: 'userName',
type: 'string',
caption: "userName"
},
{
name: 'password',
type: 'password',
caption: "password"
},
{
name: 'passwordConfirm',
type: 'password',
caption: "passwordConfirm"
},
{
name: 'mail',
type: 'string',
caption: "email"
},
{
name: 'mobile',
type: 'string',
caption: "mobile",
regex: '0[1-9][0-9]{9}'
}
];
$scope.userInputsInCreation = {};
angular.forEach($scope.headersForCreation, function (headerItem, key) {
$scope.userInputsInCreation[headerItem.name] = '';
});
}; // end of get header
$scope.getHeaders();
$timeout(function(){ console.log($scope.createForm); });
}])

How to handle selected/unselected ng-class to manage a tabbed popover

My code is as follows (the fiddle):
<div ng-controller="myCtrl">
<div ng-model="currentTab" ng-init="currentTab='Tab1'"/>
<div ng-init="popovers = [
{ name: 'Popover1',
displayName: 'Pop over with two tabs',
tabs: [
{ name: 'Tab1',
displayName: 'First tab',
description: ['First tab description']
},
{ name: 'Tab2',
displayName: 'Second tab',
description: ['Second tab description']
}
]
}
]"/>
<b>Tabs in popover</b>
<div
class="popover"
ng-repeat="p in popovers"
>
Popover name: {{p.displayName}}
<div ng-repeat="t in p.tabs"
class="tab"
ng-class="currentTab==t.name?'selected':''"
ng-click="currentTab=t.name"
>
{{t.name}}
</div>
<div ng-repeat="t in p.tabs"
class="tabContent"
ng-class="currentTab==t.name?'selected':''"
>
<p>{{t.displayName}}</p>
</div>
</div>
</div>
There is something I don't get which make the code not working perfectly, as the selected class name is never removed as one click on the tab.
When you want to modify a variable of your parent scope from within a ng-repeat you need to use $parent.currentTab.

How to get option text value using AngularJS?

I'm trying to get a text value of an option list using AngularJS
Here is my code snippet
<div class="container-fluid">
Sort by:
<select ng-model="productList">
<option value="prod_1">Product 1</option>
<option value="prod_2">Product 2</option>
</select>
</div>
<p>Ordered by: {{productList}}</p>
{{productList}} returns the value of the option, eg: prod_1. I'm trying to get the text value 'Product 1'. Is there a way to do this?
The best way is to use the ng-options directive on the select element.
Controller
function Ctrl($scope) {
// sort options
$scope.products = [{
value: 'prod_1',
label: 'Product 1'
}, {
value: 'prod_2',
label: 'Product 2'
}];
}
HTML
<select ng-model="selected_product"
ng-options="product as product.label for product in products">
</select>
This will bind the selected product object to the ng-model property - selected_product. After that you can use this:
<p>Ordered by: {{selected_product.label}}</p>
jsFiddle: http://jsfiddle.net/bmleite/2qfSB/
Instead of ng-options="product as product.label for product in products"> in the select element, you can even use this:
<option ng-repeat="product in products" value="{{product.label}}">{{product.label}}
which works just fine as well.
Also you can do like this:
<select class="form-control postType" ng-model="selectedProd">
<option ng-repeat="product in productList" value="{{product}}">{{product.name}}</option>
</select>
where "selectedProd" will be selected product.
<div ng-controller="ExampleController">
<form name="myForm">
<label for="repeatSelect"> Repeat select: </label>
<select name="repeatSelect" id="repeatSelect" ng-model="data.model">
<option ng-repeat="option in data.availableOptions" value="{{option.id}}">{{option.name}}</option>
</select>
</form>
<hr>
<tt>model = {{data.model}}</tt><br/>
</div>
AngularJS:
angular.module('ngrepeatSelect', [])
.controller('ExampleController', ['$scope', function($scope) {
$scope.data = {
model: null,
availableOptions: [
{id: '1', name: 'Option A'},
{id: '2', name: 'Option B'},
{id: '3', name: 'Option C'}
]
};
}]);
