vue js get width of element

To get the width of an element in Vue.js, you can use the ref attribute to reference the element in your template, and then access its offsetWidth property in the mounted lifecycle hook. Here are the steps to achieve this:

  1. In your template, add the ref attribute to the element you want to get the width of. For example, if you have a <div> element with a class of "my-element", you can add the ref attribute like this: <div ref="myElement" class="my-element">.

  2. In your Vue component, import the ref property from the vue package. This allows you to access the element using the reference you defined in the template. Add the following line at the top of your component: import { ref } from 'vue';.

  3. Inside your component's setup function, create a ref property and assign it to the reference name you used in the template. For example, if you used ref="myElement", create a ref property like this: const myElement = ref();.

  4. In the mounted lifecycle hook, access the width of the element using the offsetWidth property. This property returns the layout width of the element, including padding, border, and scrollbar (if any). You can assign the width to a variable for further use. Here's an example: mounted() { const elementWidth = this.$refs.myElement.offsetWidth; }.

  5. You can now use the elementWidth variable to perform any necessary operations with the width of the element.

That's it! You have successfully obtained the width of an element in Vue.js by using the ref attribute and accessing the offsetWidth property in the mounted lifecycle hook.
