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).

Modals are used to display content in a layer above the app. This paradigm is used in cases such as the creation or editing of a record, as well as various types of messaging and wizards.

modalLwc.html [LWC HTML File]

<lightning-button variant="brand"

label="Open Modal"

title="Open Modal"

onclick={openModal}

class="slds-m-left_x-small"></lightning-button>

<lightning-icon icon-name="utility:close"

alternative-text="close"

variant="inverse"

size="small" ></lightning-icon>

<span class="slds-assistive-text">Close</span>

</button>

<h2 id="modal-heading-01" class="slds-text-heading_medium slds-hyphenate">Modal Header with LWC</h2>

</header>

</p>

</div>

<button class="slds-button slds-button_neutral" onclick={closeModal}>Cancel</button>

</footer>

</div>

</section>

</template>

</template>

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.

modalLwc.js-meta.xml [LWC Metadata XML File]

<?xml version="1.0" encoding="UTF-8"?>

<target>lightning__AppPage</target>

<target>lightning__RecordPage</target>

<target>lightning__HomePage</target>

</targets>

</LightningComponentBundle>
