Convert json date to date format in jQuery

Hello everyone, I am going to share the code-sample for convert JSON date to date format using jQuery. Before implementation, you need first add the script file "date.format.js" for the reference to achieve this.


The date format js is give in the below section, please go below and see the date.format.js and copy and use it.

Table of content for JSON date format
  1. JSON date
  2. Parse JSON date to date
  3. Date format types
  4. Demo link for live output
  5. JavaScript code for date format
  6. Full example code for multiple date format


 The JSON date is
        /Date(1297246301973)/

The JQuery Code is
        var jsonDate = "\/Date(1297246301973)\/";
        var date = new Date(parseInt(jsonDate.substr(6)));

Here you can convert it to your specific given date format. i.e.

1.      Default date format: "ddd mmm dd yyyy HH:MM:ss"       
2.      Short Date format: "m/d/yy"       
3.      Medium Date format: "mmm d, yyyy"       
4.      Long Date format: "mmmm d, yyyy"       
5.      Full Date format: "dddd, mmmm d, yyyy"      
6.      Short Time format: "h:MM TT"       
7.      Medium Time format: "h:MM:ss TT"       
8.      Long Time format: "h:MM:ss TT Z"       
9.      ISO Date format: "yyyy-mm-dd"       
10.  ISO  Time format: "HH:MM:ss"       
11.  ISO  DateTime format: "yyyy-mm-dd'T'HH:MM:ss"       
12.  ISO  Utc Date Time format: "UTC:yyyy-mm-dd'T'HH:MM:ss'Z'"


The Js code sample as given below


var date = "\/Date(1297246301973)\/";
var nowDate = new Date(parseInt(date.substr(6)));
var result = "";
        result += nowDate.format("ddd mmm dd yyyy HH:MM:ss") + " : ddd mmm dd yyyy HH:MM:ss <br/>";
        result += nowDate.format("dd/mm/yyyy") + " : dd/mm/yyyy <br/>";
        result += nowDate.format("m/d/yy") + " : m/d/yy <br/>";
        result += nowDate.format("mmm d, yyyy") + " : mmm d, yyyy <br/>";
        result += nowDate.format("mmmm d, yyyy") + " : mmmm d, yyyy <br/>";
        result += nowDate.format("dddd, mmmm d, yyyy") + " : dddd, mmmm d, yyyy <br/>";
        result += nowDate.format("yyyy-mm-dd'T'HH:MM:ss") + " : yyyy-mm-dd'T'HH:MM:ss <br/>";
        result += nowDate.format("UTC:yyyy-mm-dd'T'HH:MM:ss'Z'") + " : UTC:yyyy-mm-dd'T'HH:MM:ss'Z'<br/>";

        $(function () {
            $("#lblDate").html(result);
        });

The example code as given below

In Angular 17 where the standalone true option is set by default, the app.config.ts file is generated in src/app/ and provideHttpClient(). We can be added to the list of providers in app.config.ts Step 1:   To provide HttpClient in a standalone app we could do this in the app.config.ts file, app.config.ts: import { ApplicationConfig } from '@angular/core'; import { provideRouter } from '@angular/router'; import { routes } from './app.routes'; import { provideClientHydration } from '@angular/platform-browser'; //This (provideHttpClient) will help us to resolve the issue  import {provideHttpClient} from '@angular/common/http'; export const appConfig: ApplicationConfig = {   providers: [ provideRouter(routes),  provideClientHydration(), provideHttpClient ()      ] }; The appConfig const is used in the main.ts file, see the code, main.ts : import { bootstrapApplication } from '@angular/platform-browser'; import { appConfig } from '

To encrypt and decrypt data, simply use encrypt () and decrypt () function from an instance of crypto-js. Node.js (Install) Requirements: 1.       Node.js 2.       npm (Node.js package manager) 3.       npm install crypto-js npm   install   crypto - js Usage - Step 1 - Import var   CryptoJS  =  require ( "crypto-js" ); Step 2 - Encrypt    // Encrypt    var   ciphertext  =  CryptoJS . AES . encrypt ( JSON . stringify ( data ),  'my-secret-key@123' ). toString (); Step 3 -Decrypt    // Decrypt    var   bytes  =  CryptoJS . AES . decrypt ( ciphertext ,  'my-secret-key@123' );    var   decryptedData  =  JSON . parse ( bytes . toString ( CryptoJS . enc .
