<select ng-model="item.value" ng-options="item.name for item in items">
</select>
The above will populate select option in AngularJS, but how can I add selected if my condition is met?
I want to do something like this:
<select ng-model="item.value" ng-options="item.name for item in items" if="item.name == someValueToCheckAgainst" selected endif>
</select>
Obviously the above is wrong, but I was trying to search for this to see if it is possible to do.
This is items
var items = [ 'a', 'b', 'c' ];
var someValueToCheckAgainst = 'b';
so my menu should be like this
<select ng-model="item.value">
<option value="a">a</option>
<option value="b" selected>a</option>
<option value="c">a</option>
</select>
Just figured this out
<select ng-model="form.model">
<option ng-selected="{{item == valueToCheckAgainst}}"
ng-repeat="item in items"
value="{{item}}">
{{item}}
</option>
</select>
For me this statement makes no sense.
<select ng-model="item.value" ng-options="item.name for item in items"> </select>
ng-model is current value (bound model). If your 'item' looks like ’{ value, name }' than you should define your 'select' as
<select ng-model="someValueToCheckAgainst" ng-options="item.value as item.name for item in items"> </select>
The selected option is defined by the value of the ng-model attribute. For further information you can take a look at the official documentation https://docs.angularjs.org/api/ng/directive/select.
I recommend to use ng-option directive instead of ng-repeat for select boxes, beacuse ng-option is specifically created for select box and handles options in best way. And how we can set a default or conditional option value selected in ng-option directive is using ng-init directive with it like this:
<select ng-model="item.value"
ng-options="item.name for item in items"
ng-init="condition ? item.value = items[opt index] : item.value = items[0]">
</select>

I have the following select input in my html which is populated using ng-options. I want to show the selected NAME down below in whereas I want to send the selected ID back to the controller. I get the required id from ng-model="user.category". How can I show the selected name? I also show the names in options.
<select ng-model="user.category" ng-options="category.id as category.name for category in categories" class="form-control" class="select" required>
<option value="{{category.name}}">Select a Category</option>
</select>
<p>Available On : {{user.retailerBranchId}}</p>
<select ng-model="user.category" ng-options="category for category in categories" class="form-control" class="select" required>
<option value="{{category.name}}">Select a Category</option>
</select>
<p>Available On : {{user.category.id}}</p>
If you make retailerBranchId a method you can do it with something like lodash' _.find() (or even native find). You have user.category updating according to your selection, which you say has the id in it, which you can use:
function retailerBranchId() {
return _.get(_.find(this.categories, { id: user.category }), 'name', '');
}
This also fails gracefully; if it can't find any name, or any item that matches the id, it'll return an empty string.
Edit: You would call it in a similar fashion like so:
<p>Available on: {{ user.retailerBranchId() }}</p>
Although really, it's better to use it like this:
<p data-ng-bind="'Available on: ' + user.retailerBranchId()"></p>
Can you try like a below method,
Controller to get selected Category Name:
$scope.getSelectedCategoryDetail=function(selectedCat){
angular.forEach($scope.categories, function(cat){
if(selectedCat===cat.id){
$scope.user.name=cat.name;
}
});
};
Template to have ng-change event:
<select ng-model="user.category" ng-options="category.id as category.name for category in categories" class="form-control" class="select" required>
<option value="{{category.name}}" ng-change="getSelectedCategoryDetail(user.category)">Select a Category</option>
</select>
<p>Category Id : {{user.category}}</p>
<p>Category Name : {{user.name}}</p>
How to get the object of selected option in angular js using ng-repeat? Sample fiddle is here where myself populating the dropdown as,
<select ng-model="id" ng-init="id = '-1'" ng-change="select(option)">
<option value="-1">--Select--</option>
<option ng-repeat="option in list" value="{{option.id}}">{{option.name}}</option>
</select>
If someone chose option with id=1, i want to get the object {id:1, name:'A' in $scope variable.
EDIT: Myself tried with ng-options but filtering is not happening as required based on previous dropdown selection. sample fiddle
Use option object in ng-value={{option}} and whenever u select an option your scope.id will have the desired object.
Basically ur ng-model gets populated with selected value.
Just you have to change your option to this
<option ng-repeat="option in list" value="{{'Id : ' + option.id + ' Name : ' + option.name }}">{{option.name}}</option>
Hope this will work for you and you were looking for the same result
You have 2 option to get as Object.
option 1 :
you can use Filter to get Object
<select ng-model="id" ng-init="id = '-1'" ng-change="select((list|filter:{id:id}))">
<option value="-1">--Select--</option>
<option ng-repeat="option in list" value="{{option.id}}">{{option.name}}</option>
</select>
updated fiddler here
option 2 :
set your value as Object (option)
<select ng-model="id" ng-init="id = '-1'" ng-change="select(option)">
<option value="-1">--Select--</option>
<option ng-repeat="option in list" value="{{option}}">{{option.name}}</option>
</select>
This is my HTML code
<select id="drplist" ng-model="node.field.name" data-nodrag class="form-control" ng-change="currentColumnInfo(node.field.name,Item.Type,formname)">
<optgroup label="{{primaryObjectName}}">
<option ng-repeat="Item in columnsList" value="{{Item.name}}" id="{{Item.name}}" ng-selected="true">{{Item.name}}</option>
</optgroup>
<optgroup label="{{object.formName}}" ng-repeat="object in secondaryObjectList">
<option ng-repeat="Item in object.fields" value="{{Item.name}}" id="{{Item.name}}">{{Item.name}}</option>
</optgroup>
</select>
I am getting node.field.name, item.Type, and formname as undefined when this ng-change function ng-change="currentColumnInfo(node.field.name,Item.Type,formname)" fires; can anybody help me?
You can't reference Item outside of the ng-repeat loop.
I think what you need to do is transform your data structure for columnsList and object.fields into one data structure, and use the label group by group for (key, value) in object expression for ng-options
I have a problem to read the information selected that is propagate in a select.
<div ng-show="deviceDetail != null" ng-model="example" >
<select >
<option value="NONE">Select</option>
<option ng-repeat="option in deviceDetail" ng-change="selectOption()">{{option}}</option>
</select>
<br/>
The value of the selection is: {{example}}
</div>
this is the HTML code and in the {{example}} I want to see the information that the user selected.
this is the part of the js releted:
$scope.selectOption = function() {
$scope.example = option.productName;
};
How I can fix it?
Thanks a million!
Set your example scope variable directly in <select> instead calling ng-change event and assigning into that function.
You can directly set option.name to example model with the use of ng-options too.
Here You have applied ng-model directive to div tag.
<div> is not input element so apply ng-model to <select> element here.
I would suggest to use ng-options directive for filling the selection list in <select>. ng-repeat is also fine.
Here you are binging ng-change event so in the function if requires then you can pass the object on which event is triggering so you can use that object or perform any operation on that.
Below is the modified template.
<div ng-show="deviceDetail != null">
<select >
<option value="NONE">Select</option>
<option ng-model="example" ng-options="option in deviceDetail" ng-change="selectOption(option)">{{option}}</option>
</select>
<br/>
The value of the selection is: {{example}}
</div>
You should to pass current option:
<select >
<option value="NONE">Select</option>
<option ng-repeat="option in deviceDetail" ng-change="selectOption(option )">{{option}}</option>
</select>
$scope.selectOption = function(option) {
$scope.example = option; // is there property .productName?;
};
Try this:
<div ng-show="deviceDetail != null">
<select >
<option value="NONE">Select</option>
<option ng-model="option" ng-options="option in deviceDetail" ng-change="selectOption(option)">
{{option}}</option>
</select>
<br/>
The value of the selection is: {{example}}
Js:
$scope.selectOption = function(option) {
$scope.example = option;
};
You should use ng-options
The value of the selection is: {{example}}
I'd like to set the ng-class of a optiones-element as active. Unfortunately it doesn't work.
This is my option-menu:
<select>
<option ng-repeat="item in items">{{item}}</option>
</select>
and the item "one" should be active
<select>
<option ng-repeat="item in items" ng-class="{selected: item=='one'}">
{{item}}
</option>
</select>
It doesn't work. Does anyone know how to set the option tag as active?
An example of how it works is this:
<select>
<option>Blue</option>
<option selected>Green</option>
<option>Red</option>
</select>
Below is the right way "select" works in Angularjs, notice the included ng-model directive, if missing it doesn't work.
<select ng-model="selectedItemId" ng-options="item.id as item.name for item in items">
<option value="">-- choose item--</option>
</select>
to make an item of the list active, just set SelectedItemId variable assigned to ng-model at controller side.
$scope.selectedItemId = 1; //the Id belonging to the option to be selected
I see that you want to loop over the options using ng-repeat and then manually select the right option. It is nicer to use the select directive of Angular in that case:
<select ng-model="selectedItem" ng-options="items"></select>
See https://docs.angularjs.org/api/ng/directive/select for more information.
