I'm developing application in Ionic 2. I need to add ion-select options in dynamic way, but I'm stumped on something that is probably very simple. Here is my code snippet.
<ion-select [(ngModel)]="classifications" (ngModelChange)="updateSelectedValue($event)">
<ion-option *ngFor="#key of classifications" value="key" [checked]="true">{{key}}</ion-option>
this.classifications = this.local.get('classifications')._result;
console.log('classifications: '+ this.local.get('classifications')._result);
updateSelectedValue(event:string):void {
this.selectedObject = JSON.parse(event);
console.log('selectedObject: '+this.selectedObject);
}
Output for console log:
classifications: ["Any","Agriculture, Forestry, And Fishing","Mining","Construction","Manufacturing","Transportation, Communications, Electric, Gas, And Sanitary Services","Wholesale Trade","Retail Trade","Finance, Insurance, And Real Estate","Services","Public Administration "]
I'm getting exception as well.
EXCEPTION: Cannot find a differ supporting object '["Any","Agriculture, Forestry, And Fishing","Mining","Construction","Manufacturing","Transportation, Communications, Electric, Gas, And Sanitary Services","Wholesale Trade","Retail Trade","Finance, Insurance, And Real Estate","Services","Public Administration "]' in [classifications in JobsearchPage@30:17]
Edit:
And its not setting its value to select options. I have done this in Angular 1.
<select id="classificationId" data-role="listview" data-inset="true" ng-options="classification as classification for classification in classifications " ng-model="classification" x-ng-change="update(classification)">
<option value=''>Classifications</option></select><select id="classificationId" data-role="listview" data-inset="true" ng-options="classification as classification for classification in classifications " ng-model="classification" x-ng-change="update(classification)"><option value=''>Classifications</option></select>
Edit (from comment to an answer)
export class JobsearchPage {
selectedClassification:string;
constructor(http: Http,
nav: NavController,
messagesService:MessagesService, navParams:NavParams) {
this.http = http;
this.messagesService = messagesService;
this.nav = nav;
this.classifications = new Array("t9it", 'uitut');
console.log('STP selected'+selectedClassification);
}
}
I don't use Ionic but I'm pretty sure ngModel
should point to a field that holds (or gets assigned to) the selected option not the entire list of possible options
<ion-select [(ngModel)]="selectedClassification" (ngModelChange)="updateSelectedValue($event)">
<ion-option *ngFor="#key of classifications" value="key" [checked]="true">{{key}}</ion-option>
class MyComponent {
selectedClassification:string;
}
You can try (ionChange)='func($event)' and func(event){console.log(event);}
