Vue Get Element Scroll Position:To get the scroll position of an element in Vue.js, you can use the scrollTop property. This property is used to get or set the number of pixels an element is scrolled from its top position.
First, you need to get a reference to the element using the ref attribute. Then, you can access the scrollTop property of the element using this.$refs.element.scrollTop in the Vue component’s methods or computed properties.
You can also add an event listener to the element to listen for scroll events using the @scroll directive, which will trigger a method to update the scroll position. With these techniques, you can easily get and track the scroll position of an element in Vue.js
What is the method to get the scroll position of an element in Vue?
This code demonstrates how to get the scroll position of an element in Vue. The <div> with id="app" contains a nested <div> element with a specified height and width, and the overflow property set to auto to enable scrolling.
The Vue app is created using Vue.createApp() and includes a data object with two properties, positionTop and positionLeft, both initialized to 0. The mounted() lifecycle hook is used to attach an event listener to the nested <div> element with a reference of myElement.
The event listener listens for the 'scroll' event and updates the positionTop and positionLeft properties in the data object with the current scroll position of the element using el.scrollTop and el.scrollLeft, respectively. These properties are then displayed in two separate <p> tags below the <div> element.
Overall, this code demonstrates how to use Vue’s reactivity system to update the view based on the user’s interaction with the page, specifically the scrolling of a specific element.
