I just updated the AngularJs version from AngularJS v1.4.8 to AngularJS v1.8.0 and I have a select which requires a default value. for some reason the ng-selected stop working. Can you please advise how to set the ng-selected on 1.8.0 please? (code uses an ng-model)
<input name="questionamount" class="form-control uservalue" type="number" min="0" ng-model="userInput1" ng-disabled="content.NotRelevant" ng-blur="setMainFieldAsTouched(); updateFormVisibility()" ng-change="update('userInput1',userInput1)" val-bubble>
<select name="questionperiod" class="form-control" ng-model="userInput2" ng-disabled="content.NotRelevant" ng-blur="setMainFieldAsTouched()" ng-change="update('userInput2',userInput2)" val-bubble>
<option value="">-- Select a period --</option>
<option value="48">Year</option>
<option value="24">6 Months</option>
<option value="12">Quarter</option>
<option value="4" ng-selected="true">Month</option>
<option value="5">Four Weekly</option>
<option value="2">2 Weeks</option>
<option value="1">Week</option>
</select>
<input name="questionvalue" class="form-control" type="number" min="0" readonly ng-required="content.Mandatory && !content.NotRelevant" max="{{content.TriggerLimit}}" ng-change="update('content.Value',content.Value)" ng-blur="updateFormVisibility()" ng-model="content.Value" val-bubble>
</div> ```
Thanks in advance,

From the docs:
Note: ngSelected does not interact with the select and ngModel
directives, it only sets the selected attribute on the element. If you
are using ngModel on the select, you should not use ngSelected on the
options, as ngModel will set the select value and selected options.
Which would mean, set the value of userInput2 to your default value and do not use the ng-selected attribute. See also this.

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');
Angular < 1.4 works with ng-options shown as such:
<select ng-options="option.value as option.label for option in options" ng-model="selectedValue">
With the following array of options:
[{ value:"4_220588",label:"dropdown 1-test value 1"},{value:"4_220589",label:"dropdown 1-test value 2"}]
If you look at the resultant HTML is is as you would expect:
<select ng-options="option.value as option.label for option in options" ng-model="selectedValue" class="ng-pristine ng-valid ng-touched">
<option value="" class="">-- SELECT ONE --</option>
<option value="0" label="dropdown 1-test value 1">dropdown 1-test value 1</option>
<option value="1" label="dropdown 1-test value 2">dropdown 1-test value 2</option>
</select>
As soon as you change the angular version to Angular 1.4+, the option value attribute get's messed up. Here is the output with the same ng-options using a newer version of angular:
<select ng-options="option.value as option.label for option in options" ng-model="selectedValue" class="ng-pristine ng-valid ng-empty ng-touched">
<option value="" class="" selected="selected">-- SELECT ONE --</option>
<option label="dropdown 1-test value 1" value="string:4_220588">dropdown 1-test value 1</option>
<option label="dropdown 1-test value 2" value="string:4_220589">dropdown 1-test value 2</option>
</select>
What is the solution to getting the value to show up still as the index of the array?
Here is the plnkr: http://plnkr.co/edit/3CTUI9b9ntTGWhXDNQI5?p=preview
Your application logic should not be sensitive to the value attribute in the dropdown, because ng-model will set the model correctly regardless of what is output in the HTML. If you application logic does expect a specific format for this attribute, you have 3 ways to deal with this breaking change.
Use ng-repeat instead of ng-options. This is the least recommended option, as it changes the way the select lists work significantly.
Use a track by clause to enforce the key format that you are expecting, i.e. option.value as option.label for option in options track by option.value. This presumes that option.value exists and is the value you wish to represent. http://plnkr.co/edit/TSXfkpf1lhsE9QYa2NAc?p=preview
Change your application logic to expect the hashkey instead, or preferably correct the logic so that it only relies upon ng-model.
One solution would be to use ng-repeat over the options.
<select ng-model="vm.selectedValue">
<option value="" selected disabled>-- SELECT ONE --</option>
<option ng-repeat="option in options"
value="$index"
ng-selected="option === vm.selectedValue">
{{option.label}}
</option>
</select>
Here is your updated Plunkr.
This should do the trick:
<select ng-options="index as option.label for (index, option) in options2" ng-model="vm.selectedValue">
<option value="">-- SELECT ONE --</option>
</select>
On render the value of the selected option would be string:index but will output the desired value without the type included. Here is your edited plunker with the expected result in the Selected Value:

I am using a dropdown like below
<select class="form-control"
data-ng-model="vm.priceBuilder.projectID"
data-ng-change="vm.changeProject(option)"
data-ng-options="option.pK_ProjectID as option.projectNumber for option in vm.projectList">
<option value="">Please select...</option>
</select>
and my controller binding is
changeProject(selectedProject) {
this.getSubTask(selectedProject.fK_ProjectID);
};
Here selectedProject is undefined. what is actual cause I can not understand.
clearly option is not defined you need to call the ng-change wither with the model or use the model in your function.
<select class="form-control"
data-ng-model="vm.priceBuilder.projectID"
data-ng-change="vm.changeProject(vm.priceBuilder.projectID)"
data-ng-options="option.pK_ProjectID as option.projectNumber for option in vm.projectList">
<option value="">Please select...</option>
</select>
I have some doubts with using ngoptions. I am not able to set value attribute for the option items.Here is example plunker
$scope.ListOfValues=[{optiontext:'Active',optionvalue:'opt1'},
{optiontext:'inactive',optionvalue:'opt2'},
{optiontext:'terminated',optionvalue:'opt3'}];
And my html code is
<select id="emptype" ng-model="empstatus" ng-options="emp.optionvalue as emp.optiontext for emp in ListOfValues">
</select>
The generated html is as shown below.
<select id="emptype" ng-model="empstatus" ng-options="emp.optionvalue as emp.optiontext for emp in ListOfValues" class="ng-valid ng-dirty ng-valid-parse ng-touched">
<option value="string:opt1" label="Active">Active</option>
<option value="string:opt2" label="inactive">inactive</option>
<option value="string:opt3" label="terminated">terminated</option>
</select>
I was expecting it to be as shown below
<select id="emptype" ng-model="empstatus" ng-options="emp.optionvalue as emp.optiontext for emp in ListOfValues" class="ng-valid ng-dirty ng-valid-parse ng-touched">
<option value="opt1" label="Active">Active</option>
<option value="opt2" label="inactive">inactive</option>
<option value="opt3" label="terminated">terminated</option>
</select>
So why does it add string: to the value attribute? How i can get my desired output?
It has to deal with 1.3 -> 1.4 Angular version API change - if you check this plunkr (v.1.3) it will show just indexes as values of the <option> tags.
To make it also work with Angular +1.4 you should add the following statement to your ng-options expression track by emp.optionvalue. See this plunkr (v.1.4) .
<select id="emptype"
ng-model="empstatus"
ng-options="emp.optionvalue as emp.optiontext for emp in ListOfValues track by emp.optionvalue">
</select>
But the value of the ng-model is correctly updated in both cases, see {{empstatus}} in template of my examples.
So as #ExplosionPills say that should not be a issue.
I would like to have a select with a placeholder in angularjs with bootstrap. The solutions I have found do not work with angular
Here is my angular markup:
<select ng-model="myModel"
ng-options="p.name for p in ..."
class="form-control list-selector required">
<option value='' disabled selected>Please Choose</option>
</select>
If someone has a working solution...
thanks :)
You need to add an empty option to your select:
<option value="">- Please Choose -</option>
Here is a working example: http://jsfiddle.net/DianaNassar/FShdc/
For Angularjs Versions and reactive forms , if you are using ngValue to bind values in options , the following type of solution will work:
<option value='' selected ng-value="null">Please Choose</option>
For Angular 2+ Versions something like this will work-
<select class="form-control"
formControlName="roomType"
(change)="changeRoomType($event)">
<option [ngValue]="null" selected>Room Type</option>
<option *ngFor="let room of roomTypes" [ngValue]="room">{{room}}</option>
</select>
