I currently have this:
<div>
<label for="market-type">Market Type</label>
<select id="market-type" type="text" ng-model="tradingFee.market_type">
<option value="stock">Stock Market</option>
<option value="otc">OTC Market</option>
</select>
</div>
which assigns the selected option's value to tradingFee.market_type. What I wish is to be able to do this plus assign the selected option's text to tradingFee.market_type_human_friendly_text, for example. Only being able to do one of the assignments is not enough. Is this possible somehow?
You could do this, but not with this syntax. use ng-options so that the ng-model holds both value and display name.
In your controller set array of objects:
$scope.marketType = [{id:"stock", displayName:"Stock Market"}, {id:"otc", displayName:"OTC Market"}];
and
<select id="market-type" type="text"
ng-model="tradingFee.market_type"
ng-options="mt.displayName for mt in marketType track by mt.id">
<option value="">--Select--</option>
</select>
Now the ng-model will have both id as well as value. i.e example:
tradingFee.market_type will be {id:"otc", displayName:"Stock Market"} if you select that specific item from the dropdown. With this you do not have to worry about maintaining 2 separate properties for displayName and id.
angular.module('app', [])
.run(function($rootScope) {
$rootScope.marketType = [{
id: "stock",
displayName: "Stock Market"
}, {
id: "otc",
displayName: "OTC Market"
}];
$rootScope.tradingFee = {
market_type: {
id: 'stock'
}
};
});
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<div ng-app="app">
<select id="market-type" type="text" ng-model="tradingFee.market_type" ng-options="mt.displayName for mt in marketType track by mt.id">
<option value="">--Select--</option>
</select>
{{ tradingFee.market_type }}
</div>
You could just use ng-change on your select to fire a custom event handler that sets the secondary value.
<select id="market-type" type="text" ng-model="tradingFee.market_type"
ng-change="updateSecondary()">
<option value="stock">Stock Market</option>
<option value="otc">OTC Market</option>
</select>

I have a form using a select. I'm trying to set a default value, which I want to disable, so the dropdown will show "-- select state --" as the first option and will force the user to make a selection.
My problem is it's not working and the select always starts out blank.
Here is my code:
<select ng-model="contactEditCtrl.addressData.state" style="width: 50%;">
<option ng-disabled="$index === 1" ng-selected="true">--Select State--</option>
<option value="{{state.abbreviation}}" ng-repeat="state in contactEditCtrl.states">{{state.name}}</option>
</select>
Check this one with default <option> and ng-options:
<select ng-model="contactEditCtrl.addressData.state"
ng-options="state.name as state.name for state in contactEditCtrl.states" >
<option value="" ng-disabled="true">-- select state --</option>
</select>
Demo fiddle
It will be converted to:
<select ng-model="addressData.state" style="width: 50%;"
ng-options="state.name as state.name for state in states" class="ng-valid ng-dirty">
<option value="" ng-disabled="true" class="" disabled="disabled">-- select state --</option>
<option value="0">CCCCC</option>
<option value="1">QQQQQQ</option>
</select>
The empty option is generated when a value referenced by ng-model doesn't exist in a set of options passed to ng-options. This happens to prevent accidental model selection: AngularJS can see that the initial model is either undefined or not in the set of options and don't want to decide model value on its own.
In short: the empty option means that no valid model is selected (by valid I mean: from the set of options). You need to select a valid model value to get rid of this empty option.
Taken from here
So I'd suggest writing it like this.
var app = angular.module('myApp', []);
// Register MyController object to this app
app.controller('MyController', function MyController($scope) {
this.addressData = {state: "--Select State--"};
this.states = [{abbreviation: 'a', name:'ant'}, {abbreviation: 'b', name:'asd'}, {abbreviation: 'b', name:'asd2'}]
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.22/angular.min.js"></script>
<div ng-app='myApp' ng-controller='MyController as contactEditCtrl'>
<select ng-model="contactEditCtrl.addressData.state" style="width: 50%;">
<option value="--Select State--">--Select State--</option>
<option ng-value="state.abbreviation" ng-repeat="state in contactEditCtrl.states">{{state.name}}</option>
</select>
</div>
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){
$scope.user.name=cat.name;
}
});
};
Template to have ng-change event:
<select ng-model="user.category" ng-options="category.id as category.name for category in categories" class="form-control" class="select" required>
<option value="{{category.name}}" ng-change="getSelectedCategoryDetail(user.category)">Select a Category</option>
</select>
<p>Category Id : {{user.category}}</p>
<p>Category Name : {{user.name}}</p>
I am new to angular.
I have created a row with three select box. the add field adds same row with three select box. I want to fetch the value for Field1 , Field 2 & Field3 in same object for all rows.
I am using ngRepeat to generate the rows and each select box is an individual select directive.
You can easily bind the value of a select to an attribute of an object. Try something like this:
<select ng-model="myObject.firstValue">
<option ng-repeat="option in firstList" value="{{option.name}}">
{{option.name}}
</option>
</select>
<select ng-model="myObject.secondValue">
<option ng-repeat="option in secondList" value="{{option.name}}">
{{option.name}}
</option>
</select>
To bind an ng-model to a directive use this
app.directive('directive', function () {
return {
template: '<div><input type="text" ng-model="ngModel" /></div>',
replace: true,
scope: {
ngModel : '=',
},
};
});
from here: Passing ng-model in nested directives
So, it's very simple.
You have to use [$index] in ng-model for every field in order to make it unique so that your object can easily bind into all field.
<div ng-repeat="item in vm.object">
<select name="select1"
ng-model="vm.selectedValue1[$index]"
ng-options="field1 as field1.title for field1 in vm.field1(item)">
<option value="">Select Item</option>
</select>
<select name="select2"
ng-model="vm.selectedValue2[$index]"
ng-options="field2 as field2.title for field2 in vm.field2(item)">
<option value="">Select Item</option>
</select>
<select name="select3"
ng-model="vm.selectedValue3[$index]"
ng-options="field3 as field3.title for field3 in vm.field3(item)">
<option value="">Select Item</option>
</select>
</div>
I have list of locations in a select box. On selection of a location, the corresponding incidenttypes should be displayed in another select box.
$scope.locationNames=[
{id:"Onboard",value:"On-board service"},
{id:"Clubhouse",value:"Clubhouse"},
{id:"Gate",value:"Gate"}
];
$scope.incidentTypesList={
Onboard:[
{id:"IFE faulty",value:"IFE faulty"},
{id:"223",value:"No special meal as ordered"},
{id:"Spoilt",value:"Spoilt/damaged belongings"}
];
Clubhouse:[
{id:"",value"No appointments available"},
{id:"",value="Late/delayed transport service"},
{id:"",value="Facilities not available"}
];
};
I am able to get location names in the list using the below code.
<select class="firstDropDown" ng-model="location" ng-options="item.id as item.value for item in locationNames">
<option value="">Select location</option>
</select>
Can you please help me how to implement on selection on this to show the values in another select box.
I think the solution below fits your needs. There were some syntax errors in your array which needed to be fixed.
HTML
<div ng-app="myApp" ng-controller="myAppCtrl">
<select class="firstDropDown" ng-model="location" ng-options="item.id as item.value for item in locationNames">
<option value="">Select location</option>
</select>
<select class="secondDropDown" ng-model="incident" ng-options="incident.id as incident.value for incident in incidentTypesList[location]">
<option value="">Select incident</option>
</select>
</div>
JS
var myApp = angular.module("myApp", [])
myApp.controller("myAppCtrl", function($scope){
$scope.locationNames=[
{id:"Onboard",value:"On-board service"},
{id:"Clubhouse",value:"Clubhouse"},
{id:"Gate",value:"Gate"}
];
$scope.incidentTypesList={
Onboard:[
{id:"IFE faulty",value:"IFE faulty"},
{id:"223",value:"No special meal as ordered"},
{id:"Spoilt",value:"Spoilt/damaged belongings"}
],
Clubhouse:[
{id:"",value:"No appointments available"},
{id:"",value:"Late/delayed transport service"},
{id:"",value:"Facilities not available"}
]
}
});

How do i render the values inside dropdown(selectbox options).
I need to show 'header' and 'footer' names inside selectbox.
$scope.sections = [
{
"header":{
"background-color":"#fff",
"color":"#fff"
},
"footer":{
"background-color":"#fff",
"color":"#fff"
}
}
];
I tried in the following way but not working,
<select name="section" class="form-control" ng-model ="section">
<option ng:repeat="options[0] in sections">
{{options[0]}}
</option>
</select>
You need to iterate over keys instead of values.
<option ng-repeat="(option, val) in sections[0]">
{{option}}
</option>
Or with ng-options
ng-options="option for (option, val) in sections[0]"
