Vue Get Element By Key:In Vue.js, you can retrieve a specific element in a list by its unique identifier or key using the $refs property. This is useful if you need to manipulate or access a specific element in the list, such as when you want to update its data or trigger an event on it. To use $refs, you need to assign a ref to the element when you define it in your template. Then, you can access the element by its ref name and key using the $refs property. Keep in mind that this should be used sparingly and as a last resort, as manipulating the DOM directly in Vue can lead to unexpected behavior.
How can you retrieve a specific element in a Vue.js component using its unique key?
This is a Vue.js component that renders a list of items using a v-for directive. Each item is wrapped in a div element with a unique key attribute based on its index. The component also has a mounted lifecycle hook that retrieves the second element using a ref attribute, and updates a data property with its content. The updated data is then rendered in a paragraph element using Vue’s template syntax.
