The ng-options get asynchronous . How can I set the default value?
<select class="form-control"
ng-options="item.id as item.value for item in mInsu.INS_MAX_AMOUNT track by item.id"
ng-model="custInfo.mInsu.selAmount" required>
</select>
I tried to do like this:
<select class="form-control" ng-model="custInfo.mInsu.selAmount" required>
<option ng-repeat="item in mInsu.INS_MAX_AMOUNT" value="{{item.id}}">{{item.value}}</option>
</select>
Luckly, it can meet my requirement.
So, why can't set default value in asynchronous ng-options?
Add the below lines in your controller:
$scome.custInfo.mInsu.selAmount = mInsu.INS_MAX_AMOUNT[0].id;
which assigns the first value as default.

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.

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 a drop down which contains the following values
<select class="form-control">
<option value="critical">Critical</option>
<option value="high">High</option>
<option value="medium">Medium</option>
<option value="low">Low</option>
</select>
Because of this in drop-down the value is always selected to "Critical"
In my scope i have defined the values of severity per drop-down. How do i select that ?
For example say the value is "High". How do i set the default value to high and not critical
You'll need to define at object within your scope and bind it to the ng-model of your select.
Script
$scope.form = {
"severity": "high"
};
HTML
<select class="form-control" ng-model="form.severity">
<option value="critical">Critical</option>
<option value="high">High</option>
<option value="medium">Medium</option>
<option value="low">Low</option>
</select>
There are a couple of ways to select an option with angular:
1- Bind it to a model and set the model:
<select class="form-control" ng-model="myValue">
And
$scope.myValue = 'medium';
2- You can set it in a directive by jQuery or JS:
$("#yourselectid").val('low');
in my controller, is set the two scope variables "otherscope" and "options".
otherscope: {"ID":"1", "VAL1":"X", "VAL2":"Y", ...}
othersope.ID is the value, which should be the selected one. it contains 1 object
options: [{"ID":"1", "TEXT":"Sometext"}, {"ID":"2":"Sometext2"}, ...]
options.ID are the available options to compare with otherscope.ID. it contains about 50 objects.
it works, but it take about 10 seconds to render. is this the correct way to set the selected value?
<label class="item item-input item-select">
<div class="input-label">
Options
</div>
<select ng-model="otherscope.ID">
<option ng-repeat="option in options track by option.ID" value="{{option.ID}}">{{option.TEXT}}</option>
</select>
</label>
change options to option in ng-repeat
<option ng-repeat="options in options track by option.ID" value="{{option.ID}}">{{option.TEXT}}</option>
should be:
<option ng-repeat="option in options track by option.ID" value="{{option.ID}}">{{option.TEXT}}</option>
I have a problem when I change the value of one dropdown on ng-change. It will changes the other dropdown value also even both dropdown ids are different.
anyone knows why its happening?
Below is my code:
<select class="form-control" id="Billable{{$index}}" ng-init="invoice.source_item=''" ng-model="invoice.source_item" ng-change="BillableItemDetails(invoice.source_item,$index)">
<option class="ng-binding" value="">Select Billable Item...</option>
<option class="ng-binding" ng-repeat="BillableItem in BilableItemsList" value="{{BillableItem.id}}">{{BillableItem.name}}</option>
</select>
use different ng-model variable with different dropdown
Here is Plnkr
HTML
<select ng-model="dd1_Value" ng-change="changedd(ddValue.key)">
<option ng-repeat="d in dd track by d.id">{{d.name}}</option>
</select>
<p>DropDown 1 : {{dd1_Value}}</p>
<select ng-model="dd2_Value">
<option ng-repeat="d in dd track by d.id">{{d.name}}</option>
</select>
<p>DropDown 2 : {{dd2_Value}}</p>
Controller
app.controller('MainCtrl', function($scope) {
$scope.dd = [
{id:1,name:'a'},
{id:2,name:'b'},
{id:3,name:'c'},
{id:4,name:'d'},
{id:5,name:'e'},
{id:6,name:'f'}
]
});
Change the value of ng-model="invoice.source_item" to a unique scope variable for each DropDown.
<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>
