Essentially, I am searching for a computed property that will evaluate to true when the window.innerwidth is 768px or less and to false when it exceeds 768px.
This is what I have attempted:
computed: {
isMobile() {
if (window.innerWidth <= 768) {
return true
}
return false
}
}
However, this computes the property only once, so any changes in window size are not reflected. How can I address this issue?
To ensure responsiveness, you can add an event listener to the window in your Vue component:
new Vue({
el: "#app",
data() { return { windowWidth: window.innerWidth } },
mounted() {
window.addEventListener('resize', () => {
this.windowWidth = window.innerWidth
console.log(this.isMobile)
})
},
computed: {
isMobile() {
return this.windowWidth <= 768
}
}
})
Another option is utilizing the Vuetify framework:
computed: {
isMobile() {
return this.$vuetify.breakpoint.smAndDown
},
},
Source: https://vuetifyjs.com/en/features/breakpoints/#breakpoint-service-object
For computed properties to update, they rely on changes in their dependencies. This means that the isMobile property may not be reactive.
