Salesforce PDI Dumps Questions Answers

The correct answers are option C and option D. Lightning Web Components are self-contained and reusable units of an application that follow web standards and can leverage modern web features. They also benefit from a rich component ecosystem that includes standard components, custom components, and third-party components. Visualforce, on the other hand, is a legacy framework that relies on server-side rendering and proprietary markup. It does not offer the same level of modularity, performance, and interoperability as Lightning Web Components. References: The information can be referenced from the official Salesforce documentation and learning materials available on Trailhead. Specifically, it aligns with the objectives outlined in Lightning Web Components Basics, where the benefits and features of Lightning Web Components are discussed. Lightning Web Components Basics

 The issue is that the value of the account type field is not being displayed correctly on the Visualforce page. This can be resolved by adding a getter method for the actType attribute in the custom controller. A getter method is used to retrieve the value of a private variable, ensuring that it’s read-only and cannot be modified by external classes or pages, thus maintaining encapsulation and security. References: The need for getter methods and their usage can be referenced in Apex basics where encapsulation, getters, and setters are discussed: Apex Basics & Database

To include a custom SVG in a Lightning web component, you need to follow these three steps:

• Upload the SVG as a static resource. You can use the Static Resource page in Setup or the Salesforce CLI to upload the SVG file as a static resource. You need to give it a name and a description, and optionally specify a cache control setting1.
• Import the static resource and provide a getter for it in JavaScript. In your Lightning web component’s JavaScript file, you need to import the static resource using the @salesforce/resourceUrl module. Then, you need to define a getter function that returns the URL of the static resource2. For example:

JavaScript

import { LightningElement } from 'lwc';

import customSVG from '@salesforce/resourceUrl/customSVG';

export default class MyComponent extends LightningElement {

get svgURL() {

return customSVG;

}

}

• Reference the getter in the HTML template. In your Lightning web component’s HTML template, you need to use the

In the JavaScript file, you also need to define a handleSVGLoaded method that uses the XMLHttpRequest object to fetch the SVG content and append it to the 

JavaScript

handleSVGLoaded(event) {

const svgElement = event.target;

const xhr = new XMLHttpRequest();

xhr.open('GET', this.svgURL, true);

xhr.onload = () => {

svgElement.innerHTML = xhr.responseText;

};

xhr.send();

}
