I'm using Choices.js for multi select and for a select with a search box. I am also using angular.js to populate the data but it doesn't seem to work. Can anybody help me with populating the options dynamically.
The data is being retrieved using Ajax.
This is what I've tried
<label for="docno" class="col-form-label">Name :</label>
<select id='docno' class="choices form-select" ng-model="docno" ng-change='getDocs()' required="true">
<option ng-repeat="d in documents" ng-value="d.docno" selected='selected'>{{d.name}}</option>
</select>
You can use setValue in choices instance like below :
var choices = new Choices(document.getGetElementById("docno"));
var myDynamicItems = [
{
value: 'Value 1',
label: 'Label 1',
id: 1
},
{
value: 'Value 2',
label: 'Label 2',
id: 2
}
];
inst.choices.setValue(myDynamicItems);
if you use default single select from choices.js, just remove data-trigger attribute and it should work fine.

I have a JSON saved that has plenty information:
I am able to fill a select menu with all the names of each element inside the JSON this way:
<select ng-model="car.marca" ng-options="item.brakeId as item.name for item in fillBreaks" class="form-control cforms" required>
<option value="" disabled selected>Sleccionar Marca</option>
</select>
Getting this as result: a select menu filled with the names:
I am able to get the BreakId of the selected element, in this case is saved in 'car.marca' using ng-model.
ng-model="car.marca"
My question is, Based on the selected element lets say 'BrakeId: 9' how can I display the rest of the information of that selected id?
I want to display the price, description, stock, and so on.
You can get the selected object by doing a find on fillBreaks (should be fillBrakes?) for an object with a matching brakeId using ng-change like below. This will allow you to display the additional brake information while keeping car.marca true to holding just a brakeID.
var exampleApp = angular.module('exampleApp', []);
exampleApp.controller('ExampleController', ['$scope', function($scope) {
$scope.car = null;
$scope.fillBreaks = [
{ brakeId: 0, name: 'Brake A', description: 'Good brakes', price: 100, stock: 1 },
{ brakeId: 1, name: 'Brake B', description: 'Great brakes', price: 200, stock: 1 },
{ brakeId: 2, name: 'Brake C', description: 'The best brakes', price: 300, stock: 1 }
];
$scope.brakeInfo = null;
$scope.getBrakeInfo = function(brakeId) {
$scope.brakeInfo = $scope.fillBreaks.find(function(item){return item.brakeId == brakeId});
}
}]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="exampleApp" ng-controller="ExampleController">
<select ng-model="car.marca" ng-options="item.brakeId as item.name for item in fillBreaks" ng-change="getBrakeInfo(car.marca)" class="form-control cforms" required>
<option value="" disabled selected>Sleccionar Marca</option>
</select>
<p>{{ brakeInfo }}</p>
</div>
You can change your ng-options to grab the entire selected object, instead of just it's ID.
ng-options="item as item.name for item in ctrl.fillBreaks"
See this JSFiddle for example
P.S. A little trick to remove the Placeholder option from the dropdown is to add style="display: none;" to it, so that it can't be intentionally selected; also illustrated in the JSfiddle
Well, I have two problems that worry me a lot ... First, I don't know how to give a default value to the select box.
And I I'm not able to change the value of the select box via an event click ... I've created a fiddle example if someone could give me a hand it would be very appreciated!
HTML
<select id="FilterBox" data-bind="value: siteGetOne">
<option value="-2">City Wide</option>
<!-- ko foreach: sites -->
<option data-bind="text: name, value: $data"></option>
<!-- /ko -->
</select>
Selection Option Object : <span data-bind="text: siteGetOne"></span><br/>
Selection Option name : <span data-bind="text: siteGetOne().name"></span><br/>
Selection Option id : <span data-bind="text: siteGetOne().id"></span><br/>
Set Value to 1
Set Value to 2
Set Value to 3
JS
var viewModel = function() {
var self = this;
setValue = ko.observable();
self.sites = [
{ name: 'Site 1', id: 1},
{ name: 'Site 2', id: 2},
{ name: 'Site 3', id: 3}
];
self.siteGetOne = ko.observable(self.sites[2].id);
self.siteGetOne.subscribe(function (newValue) {
console.log(newValue);
}, self);
}
ko.applyBindings(new viewModel());

Edited Final version : http://jsfiddle.net/xjYcu/286/
couple things you may want to change.
here is the entire fiddle. http://jsfiddle.net/xjYcu/283/
the first one is you should use the options binding for your select.
<select id="FilterBox" data-bind=" options: sites,
optionsText: 'name',
value: siteGetOne,
optionsCaption: 'Choose...'">
</select>
also try changing your click bindings to something like this so you can pass in your parameter.
Set Value to 1
Set Value to 2
Set Value to 3
I am new to angularjs and still learning the language.
I created a select box in an html and I want to populate it with a variable in my controller.
I am able to get the variable in the html using {{variablename}}, but I am not able to get the sub objects within it.
Please see my code here.
You can see that it displays "repeatSelect" in the html but if i try to index an object within it, it doesn't show.(getID is always empty)
Controller has a $scope variable as follows
controller('ExampleController', ['$scope', function($scope) {
$scope.repeatSelect = null;
$scope.data = {
availableOptions: [
{id: '1', name: 'Option A'},
{id: '2', name: 'Option B'},
{id: '3', name: 'Option C'}
],
};
}]);
In the html code,
<tt>repeatSelect = {{repeatSelect}}</tt><br/>
<tt>getID = {{repeatSelect.id}}</tt><br/>
repeatSelect works fine, but repeatSelect.id doesn't.
Please guide
Use ng-options built in directive instead https://docs.angularjs.org/api/ng/directive/ngOptions.
It is designed specifically to work with HTML select lists and has plenty of powerful options.
<div ng-controller="ExampleController">
<label> Repeat select: </label>
<select ng-options="option as option.name for option in data.availableOptions track by option.id" ng-model="repeatSelect"></select>
<hr>
<tt>repeatSelect = {{repeatSelect}}</tt><br/>
<tt>getID = {{repeatSelect.id}}</tt><br/>
</div>

Currently, I've got something like this (simplified):
<select ng-model=model.policyHolder ng-options="person.index as person.name for person in model.insurance.persons">
<option value>Someone else
</select>
This creates a dropdown with options for person names and an empty one for "someone else" at the top. The question is, how do I get that empty option at the bottom of the dropdown?
I would very much like to keep using ng-options for this, especially since controlling the position of the default option seems like too small a change to justify the slightly more verbose <option ng-repeat> way.
Thanks!
use option with value=""
Like:
<select ng-model="model.policyHolder" ng-options="person.index as person.name for person in model.insurance.persons">
<option value="">Someone else</option>
</select>
If you want to show Someone else at the bottom when click on drop-down list you can use.
<select ng-model="model.policyHolder">
<option ng-repeat="person in model.insurance.persons" value="{{person.index}}">{{person.name}}</option>
<option value="">Someone else</option>
</select>
The other answers seem to add an element at the top, not the bottom.
If you want something at the end of the list, you could always add it in the JavaScript.
See working plunk, adapted from the angular select documentation.
Main part copied below:
(function(angular) {
'use strict';
angular.module('defaultValueSelect', [])
.controller('ExampleController', ['$scope', function($scope) {
$scope.data = {
availableOptions: [
{id: '1', name: 'Option A'},
{id: '2', name: 'Option B'},
{id: '3', name: 'Option C'}
],
selectedOption: {id: '3', name: 'Option C'} //This sets the default value of the select in the ui
};
// Add the alternative option
// may need to use $digest, depending on where in the process you do this.
$scope.data.availableOptions.push({ id: '', name: 'None of the above'})
}]);
})(window.angular);
Code in controller:
$scope.infoOptions = [
{ name: 'Select Option', value: '0' },
{ name: 'Some Option', value: '1' }
];
HTML:
<select data-ng-model="nothing" data-ng-options="info.name for info in infoOptions ">
</select>
Angular puts that damn empty option at the top/selected by default. I've seen some answers to this question that suggest selecting a default option in the $scope for the form, but this select box is in a template in a dynamic form (ie. can be a number of select boxes). This is really only for demonstration purposes - is there anyway I can get rid of that empty option in a template?
