Hi guys welcome back with another post on lightning web component series. today in this post we are going to learn that how we can create custom modal or popup window in salesforce lightning web component (LWC).

modalLwc.js [LWC JavaScript File]

import { LightningElement,track } from 'lwc';

export default class ModalLwc extends LightningElement {

@track bShowModal = false;

/* javaScipt functions start */

openModal() {

// to open modal window set 'bShowModal' tarck value as true

this.bShowModal = true;

}

closeModal() {

// to close modal window set 'bShowModal' tarck value as false

this.bShowModal = false;

}

/* javaScipt functions end */

}

@track : Marks a property for internal monitoring. A template or function using
this property forces a component to rerender when the property’s value changes.
Use this to store values locally, especially as a user interacts with your
component.
