To make a computed property in Vue.js dependent on the current time, you can utilize a combination of JavaScript’s Date object and Vue’s reactivity system.
For example, we write
The current time is: {{ currentTime }}
The current hour is: {{ currentHour }}
In this example, we have a computed property
currentHour that depends on the currentTime data property.We initialize
currentTime with the current date and time.We update
currentTime every second using setInterval to ensure that the computed property is re-evaluated as time progresses.With this setup,
currentHour will automatically update every second to reflect the current hour based on the system time.We can similarly create computed properties dependent on other time-related aspects such as minutes, seconds, etc., by accessing different methods of the
Date object.
