Json data binding with calendar in Angular Calendar component

27 Sep 20233 minutes to read

In most of the real cases, the model data will be available with JSON format only. Here we have showcased Calendar component by setting JSON string to value property. In this JSON, we have used ISO formatted date string which is frequently used date format to get proper date and time value without any misreading.
Also our Calendar component supports the ISO formatted date value, so parsed JSON value can be directly set to Calendar model.

app.component.ts

import { Component } from '@angular/core';
export interface User {
    selectedDate: Date;
}
export interface JSONUser {
    selectedDate: string;
}
@Component({
    selector: 'app-root',
    template: `
    <!-- To Render Calendar -->
    <ejs-calendar id="calendar" [(value)]='user.selectedDate' (change)='onChange($event)'></ejs-calendar>
    <div class="valuestring">
    <b>User model</b>:  <br/>
    <br/><br/>
    <b>JSON Data</b>: <br/>
    <br/><br/>
    </div>`
})
export class AppComponent {
    public user?: User | any;
    public JSONData: JSONUser = JSON.parse('{ "selectedDate": "2018-12-18T08:56:00+00:00"}');
    public model_result: string = JSON.stringify(this.JSONData);

    constructor() {}
    public ngOnInit() {
        this.user = this.JSONData;
    }
    onChange(args: any) {
        this.JSONData.selectedDate = args.value;
        this.model_result = JSON.stringify(this.JSONData);
    }
}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
//Syncfusion ej2-angular-calendars module
import { CalendarModule } from '@syncfusion/ej2-angular-calendars';
import { AppComponent } from './app.component';


/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        CalendarModule //declaration of ej2-angular-calendars module into NgModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
