I have some problem with my selects. Here is code:
<select ng-model="car" ng-options="car.name for car in cars track by car.id" class="form-control">
<option value="">Choose model name</option>
</select>
<br />
<select ng-options="model.name for model in car.models track by model.id" ng-model="model" class="form-control">
<option value="">Choose car</option>
</select>
I want that when i visit this page that the two selects have default values. For example in first select - "BMW" and in second - "528I" at the same time. I'm trying to do this solution:
<select ng-model="car" ng-init="car.id = 1" ng-options="car.name for car in cars track by car.id" class="form-control">
<option value="">Choose model name</option>
</select>
<br />
<select ng-init="model.id = 5" ng-options="model.name for model in car.models track by model.id" ng-model="model" class="form-control">
<option value="">Choose car</option>
</select>
But it work only for the fisrt select. (And when i choose the name in first select with name with id = 1, the second select to switch to the model with id = 5;)
I don't know how to reailze default values in two selects at the same time.
Have you any ideas?
Here is plunker
You could just use ng-init, like this:
<select ng-init="car=cars[0]" ng-model="car" ng-options="car.name for car in cars" class="form-control">
<option value="">Choose model name</option>
</select>
<br />
<select ng-init="model=car.models[0]" ng-options="model.name for model in car.modelsd" ng-model="model" class="form-control">
<option value="">Choose car</option>
</select>
UPDATE
The syntax of your select was a bit off, you actually don't need to use track by unless you are grouping the values of your select, which you are not. I think that what you actually wanted was to have the model bound to the id of the 'car' rather than having the model bound to the car itself. If that's what you want you could do it like this:
<select ng-init="car=1" ng-model="car" ng-options="car.id as car.name for car in cars" class="form-control">
<option value="">Choose model name</option>
</select>
But then you would have to do something very awkward in order to render the second select with the models of the car, because in that case your variable car would be an int (the id of the car), not the 'car' object, so you would have to do something like this:
<select ng-init="model=5" ng-model="model" ng-options="model.id as model.name for model in ((cars | filter:{id:car})[0].models)" class="form-control">
<option value="">Choose car</option>
</select>
Which is just as awkward as it looks, but if that's what you want... well, here you have an example:
Working example
A better idea in my opinion would be to have the models pointing to the objects, and if you want to initialize the selects through the id, you could do this in the ng-init :
<select ng-init="car=(cars|filter:{id:1})[0]" ng-model="car" ng-options="car.name for car in cars" class="form-control">
<option value="">Choose model name</option>
</select>
<br />
<select ng-init="model=(car.models|filter:{id:5})[0]" ng-options="model.name for model in car.models" ng-model="model" class="form-control">
<option value="">Choose car</option>
</select>
Working Example
You may use ng-model attribute in your controller and assign a default variable like
<div ng-controller="MyController" >
<form>
<select ng-model="myForm.car">
<option value="nissan">Nissan</option>
<option value="toyota">Toyota</option>
<option value="fiat">Fiat</option>
</select>
</form>
<div>
{{myForm.car}}
</div>
</div>
<script>
angular.module("myapp", [])
.controller("MyController", function($scope) {
$scope.myForm = {};
$scope.myForm.car = "nissan";
} );
</script>

I don't know why this is not adding a default selected view:
I thought ng-init would make it have a default selected view.
How do I make the drop down box menu have a default selected value?
<select ng-init="selectedCar = Cars[0]" ng-model="selectedCar" class="form-control" ng-required="true">
<option value="" selected>Select a job title</option>
<option ng-repeat="car in Cars" ng-value="car.firstname car.lastname">
{{car.firstname}} {{car.lastname}}
</option>
</select>
You can try to initialize selectedCar in your controller rather ng-init.
Try the below code.
In your controller initialize it.
For e.g:
$scope.selectedCar = $scope.Cars[0];
And in the template:
<select ng-model="selectedCar" class="form-control" ng-required="true">
<option value="" selected>Select a job title</option>
<option ng-repeat="car in Cars" ng-value="car.firstname car.lastname" ng-selected="selectedCar.id == car.id">
{{car.firstname}} {{car.lastname}}
</option>
</select>
Or
You can try using ng-options. Reference Another way by using ng-options
You can set the default value for the select element by binding the ng-model with the variable you assigned with ng-init since ng-init doesn't assign the default value for the select and option components, but the default value to a variable in the scope.
Try using selected in option to select the default value.
<select ng-init="selectedCar = Cars[0]" ng-model="selectedCar" class="form-control" ng-required="true">
<option value="" selected>Select a job title</option>
<option ng-repeat="car in Cars" ng-value="car.firstname car.lastname" selected>
{{car.firstname}} {{car.lastname}}
</option>
Or you can use ng-selected
<select ng-init="selectedCar = Cars[0]" ng-model="selectedCar" class="form-control" ng-required="true">
<option value="" selected>Select a job title</option>
<option ng-repeat="car in Cars" ng-value="car.firstname car.lastname" ng-selected="$first">
{{car.firstname}} {{car.lastname}}
</option>
I want to set whatever I choose i want to save it to viewmodel but I can't figure out how to set option that I selected to ng-model. If nothing is selected value will be select one. Available options are YES (true) / NO (false). Thanks guys
<select automationid="APR" name="cost"
class="ddl"
ng-model="tempDefaultCost.cost"
ng-options="item.value as item.text for item in costFlyoutCtrl.trueFalseLookup">
<option value="">Select One</option>
</select>
If I understood your question correctly, You can add an extra option to select box which is disabled and selected:
with ng-repeat:
<select automationid="APR" name="cost" class="ddl" ng-model="$ctrl.selectedItem">
<option value="" disabled selected>Select one</option>
<option ng-repeat="x in $ctrl.items">{{x.label}}</option>
</select>
and also with ng-options:
<select automationid="APR" name="cost"
class="ddl"
ng-model="$ctrl.selectedItem"
ng-options="x.label for x in $ctrl.items">
<option value="" disabled selected>Select one</option>
</select>
And in your controller:
this.items = [{value: true, label: 'TRUE'}, {value: false, label: 'FALSE'}];
this.selectedItem;
DEMO
HTML code:
<select name="category" onchange="change(this.selectedIndex)">
<option selected disabled hidden>Choose your category</option>
<option value="1">TVs</option>
<option value="2">Laptops</option>
<option value="3">Smartphones</option>
<option value="4">Peripherals</option>
<option value="5">Components</option>
<option value="6">Cameras</option>
</select>
PHP code:
$category = $_POST['category'];
$db->INSERT("INSERT INTO items Values(NULL,'$name','$category','$brand','$nick','$review','$rating')");
I want to save to base by POST my category. For example TVs. And the program saves "value" for example "1". When the value didn't exist it worked, but now I need it to JS function. How to do - name="category" reads option, not value?
So basically what a value is for is to indicate what an input should hold as a content,
so consider doing this
<select name="category" onchange="change(this.selectedIndex)">
<option selected disabled hidden>Choose your category</option>
<option value="TVs">TVs</option>
<option value="Laptops">Laptops</option>
<option value="Smartphones">Smartphones</option>
<option value="Peripherals">Peripherals</option>
<option value="Components">Components</option>
<option value="Cameras">Cameras</option>
</select>
hope it helped!!
I would like to have a dynamic select option values bind to select dropdown.
<div ng-repeat="condition in conditions">
<div class="form-group">
<select ng-model="condition.Description" class="form-control">
<option value="">- Select -</option>
<option ng-value="{{age.Description}}" ng-repeat="age in ageConditions">{{age.Description}}</option>
</select>
</div>
</div>
I like
age in ageConditions
to be dynamic. I also tried ng-options="dynamicOptions" but it always bind to the same list.
I want to achieve this with ng-repeat.
Repeat 1:
<select ng-model="condition.Description" class="form-control">
<option value="">- Select -</option>
<option ng-value="ageCondition1">ageCondition1</option>
<option ng-value="ageCondition2">ageCondition2</option>
</select>
Repeat 2:
<select ng-model="condition.Description" class="form-control">
<option value="">- Select -</option>
<option ng-value="yearsCondition1">yearsCondition1</option>
<option ng-value="yearsCondition2">yearsCondition2</option>
</select>
As shown i want the option in select to be dynamic in ng-repeat.
Any idea?
<select ng-model="condition.Description" class="form-control">
<option value="">- Select -</option>
<option value="getValue(age, $parent.$index)" ng-repeat="age in ageConditions"> getText(age, $parent.index)</option>
</select>
Please note that $parent.$index is used.
the dynamic nature van be achieved used functions which return the value based in $index.
$scope.getValue = function(age, index) {
if(index === 1) return age.Desciption else age.years;
}
$scope.getText = function(age, index) {
if(index === 1) return age.Desciption else age.years;
}
hope this helps
Solved this by creating a directive that created a new scope for select.
I have this select element in a row (of which there can be a few) which represents an item. But the scope for manufacturer does not update when this is selected. The default for the item's manufacturer attribute is null (since when it's created - it no manufacturer has been selected yet)
<select ng-model="manufacturer" ng-options="manufacturers.name for manufacturers in manufacturers" ng-change="change()" class="ng-valid ng-dirty">
<option value="" selected="selected" class=""> --Select a Manufacturer--</option>
<option value="0">Choice1</option>
<option value="1">Choice2</option>
<option value="2">Choice3</option>
</select>
I guess my question is - how do I get the manufacturer attribute in the item to update with the select box?
Thanks!
If it helps - here's the scope of the cams item:
$scope.cams = [
{channels:1, manufacturer:null},
{channels:1, manufacturer:null}
];
Turns out ng-model="manufacturer" should have been ng-model="cam.manufacturer":
<select ng-model="cam.manufacturer" ng-options="manufacturers.name for manufacturers in manufacturers" ng-change="change()" class="ng-valid ng-dirty">
<option value="" selected="selected" class=""> --Select a Manufacturer--</option>
<option value="0">Choice1</option>
<option value="1">Choice2</option>
<option value="2">Choice3</option>
</select>
Now it works perfectly.
You could use this:
HTML
<selectmultiple ng-model="selectedValues">
<option ng-repeat="lang inLanguages" value="{{lang.name}}" ng-click="selected(selectedValues)">{{lang.name}}</option>
</select>
angularjs:
$scope.selected = function(nowSelected){
$scope.selectedValues = [];
if( ! nowSelected ){
return;
}
angular.forEach(nowSelected, function(val){
$scope.selectedValues.push(val);
});
};
