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:
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 theref
attribute like this:<div ref="myElement" class="my-element">
.In your Vue component, import the
ref
property from thevue
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';
.Inside your component's
setup
function, create aref
property and assign it to the reference name you used in the template. For example, if you usedref="myElement"
, create aref
property like this:const myElement = ref();
.In the
mounted
lifecycle hook, access the width of the element using theoffsetWidth
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; }
.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.
