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');

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 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>
Guys after I used the angular directive ng-options I got this result
<select name="users" id="users" ng-options="user.id as user.name for user in users" ng-model="user">
<option value="number:1" label="Developers">Ahmed</option>
<option value="number:2" label="Designers">Jon</option>
<option value="number:3" label="HR">Astm</option>
<option value="number:4" label="Doctor">Fady</option>
</select>
<select name="colors" id="colors" ng-options="color.code as color.name for color in colors" ng-model="color">
<option value="string:ff0000" label="Developers">Red</option>
<option value="string:ffffff" label="Designers">White</option>
<option value="string:000000" label="HR">Black</option>
</select>
why the option value contains the data type such as number:1 or string:ffffff ??
how I can remove the data type from it and keeping only the value ?
Add track by [id] at the end of ng-options.
In your case it would be:
ng-options="user.id as user.name for user in users track by user.id"
and
ng-options="color.code as color.name for color in colors track by color.code"
Right now there is not option in angular to remove that type. If you need that, use custom directive with ng-option as parent.
I have an AngularJS page for editing surgeries, but I can't get any of the <select>'s to show the current value. All the other fields in the form show their current values so I'm not sure what I'm doing wrong.
I have a factory set up with ngResource, this is in my controller.
// Supporting Data
SurgeryData.get({'accessToken':$rootScope.accessToken})
.$promise.then(function(response){
$scope.surgeryData = response.surgeryData;
});
// Surgery Data
SurgeryServices.get({'surgeryId':$stateParams.surgeryId,'accessToken':$rootScope.accessToken})
.$promise.then(function(response){
$scope.surgeryDetails = response;
$scope.formData.surgeryId = $scope.surgeryDetails.surgery.id;
...
$scope.formData.surgeryStatus = $scope.surgeryDetails.surgery_status;
...
$log.log( angular.toJson( $scope.formData.surgeryStatus ) );
$log.log( angular.toJson( $scope.surgeryData.surgery_status ) );
});
This is the HTML for Surgery Status
<select class="form-control" ng-model="formData.surgeryStatus" ng-options="status.name for status in surgeryData.surgery_status"></select>
and this is what I get in the console from my 2 $logs
$scope.formData.surgeryStatus
{"id":16,"name":"Ready For Pick-Up"}
$scope.surgeryData.surgery_status
[{"id":13,"name":"Inventory Not On Site"},{"id":14,"name":"Inventory On Site"},{"id":16,"name":"Ready For Pick-Up"},{"id":15,"name":"Sterilized For Surgery"}]
The <select>'s in the form have all the options but (for this example) Ready for Pick-Up is not selected and I have an empty ? option added to the select
<select class="form-control ng-pristine ng-valid" ng-model="formData.surgeryStatus" ng-options="status.name for status in surgeryData.surgery_status">
<option value="?"></option>
<option value="0">Inventory Not On Site</option>
<option value="1">Inventory On Site</option>
<option value="2">Ready For Pick-Up</option>
<option value="3">Sterilized For Surgery</option>
</select>
ng-init should be the way to go.
View:
<select class="form-control ng-pristine ng-valid" ng-init="formData.surgeryStatus = selected" ng-model="formData.surgeryStatus" ng-options="status.name for status in surgeryData.surgery_status track by status.id">
<option value="?"></option>
<option value="0">Inventory Not On Site</option>
<option value="1">Inventory On Site</option>
<option value="2">Ready For Pick-Up</option>
<option value="3">Sterilized For Surgery</option>
</select>
Viewmodel:
$scope.selected = $scope.surgeryDetails.surgery_id;
ng-init will find the matching value from your options and select it when loading. Be sure to set your ng-model equal to whatever value you want selected, which looks like your Id in this case?
Simply trying to make a default selected value in Angular but thus far I am having no luck.
HTML Before Compile:
<select ng-options="select.Value as select.Name for select in ruleSelect" ng-model="rule.MatchLogic" ng-init="rule.MatchLogic = 0" ></select>
HTML In Browser Source:
<select ng-options="select.Value as select.Name for select in ruleSelect" ng-model="rule.MatchLogic" class="ng-pristine ng-valid">
<option value="?" selected="selected"></option>
<option value="0">All</option>
<option value="1">At Least</option>
<option value="2">At Most</option>
</select>
How do I make value=0 (All) the default selected value.
All you need to do is set your ng-model value rule.MatchLogic to equal the corresponding value in the options. The options you use are ruleSelect.
So for example, set rule.MatchLogic = ruleSelect[someSelector].Value; inside your controller.
