Vue Get Element Property:To get an element’s property using window.getComputedStyle in Vue, you can use the this.$refs object to reference the element and access its computed styles.
First, use this.$refs to access the element and save it to a variable. Then, use window.getComputedStyle with the variable to get the element’s computed styles. Finally, use the getPropertyValue method to retrieve a specific property from the computed styles object.
What is the syntax for getting an element property in Vue.js?
In the mounted() lifecycle hook, the myElement constant is created using the $refs property, which is a special property in Vue.js that provides a way to access elements in the component’s template. The window.getComputedStyle() method is used to get the computed style of the myElement element. The console.log() method is used to log the elementStyle object to the console.
Finally, the values of the computed style properties are assigned to the component’s data properties using the getPropertyValue() method. The values are then displayed in the pre elements using Vue.js template syntax {{ }}.
