In this example, this.refs references the directive lwc:ref='myDiv' to access the at runtime.In Salesforce, new Lightning web components (LWCs) can be created and added to projects that already contain Aura components. To use refs, add the lwc:ref directive to your element and assign it a value. Refs locate DOM elements without a selector and query elements in a specified template only. Using JavaScript to manipulate the DOM isn’t recommended when programming Lightning web components, but some third-party JavaScript libraries require it.Įnables a third-party web component or custom element to be rendered as a native web component in an LWC template.
