Ember.js EmberArray isAny() Method

Last Updated : 18 Jan, 2023

Ember.js is an open-source JavaScript framework used for developing large client-side web applications which is based on Model-View-Controller (MVC) architecture. Ember.js is one of the most widely used front-end application frameworks. It is made to speed up development and increase productivity. Currently, it is utilized by a large number of websites, including Square, Discourse, Groupon, Linked In, Live Nation, Twitch, and Chipotle.

The isAny() method is used to check if anyone of the item in the array has the desired value or not.

Syntax:

isAny( key, value );

Parameters:

key: It is the property name that we want to check.
value: It is the value to test against. The default value is true.

Returns: True if, for any one of the items in the array, the passed property resolves to the desired value.

To run the following examples you will need to have an ember project with you. To create one, you will need to install ember-cli first. Write the below code in the terminal:

npm install ember-cli

Now you can create the project by typing in the following piece of code:

ember new <project-name> --lang en

To start the server, type:

ember serve

Example 1: Type the following code to generate the route for this example:

ember generate route isAny1

import Route from '@ember/routing/route';  export default class DetailsRoute     extends Route {     details = [         {             name: 'Aaksh',             mobile: '9811129967',             city: 'Delhi',             country: 'India',             gender: 'M',             zipCode: '800020',         },         {             name: 'Sweta',             mobile: '9456712890',             city: 'Mumbai',             country: 'India',             gender: 'F',             zipCode: '400001',         },         {             name: 'Satyam',             mobile: '2222222222',             city: 'Raipur',             country: 'India',             gender: 'M',             zipCode: '110012',         },         {             name: 'Shandya',             mobile: '1122113322',             city: 'Bangalore',             country: 'India',             gender: 'F',             zipCode: '530068',         },         {             name: 'Ayushi',             mobile: '2244668800',             city: 'Thana',             country: 'India',             gender: 'F',             zipCode: '302001',         },     ];     someMoreDetails = [         {             name: 'Yogesh',             mobile: '1133557799',             city: 'Chennai',             country: 'India',             gender: 'F',             zipCode: '600001',         },         {             name: 'Sunny',             mobile: '9911000000',             city: 'Masore',             country: 'India',             gender: 'M',             zipCode: '574142',         },         {             name: 'Khushi',             mobile: '8888888888',             city: 'Pune',             country: 'India',             gender: 'F',             zipCode: '111045',         },     ];     city;     name;     code;     model() {         return this.details;     }     setupController(controller, model) {         super.setupController(controller, model);         controller.set('details', this.details);         controller.set('someMoreDetails',             this.someMoreDetails);         controller.set('city', this.city);         controller.set('code', this.code);         controller.set('name', this.name);     } }
