I am currently experimenting with the beta version of Vue 3 and encountering an issue while trying to access a ref in the setup function. Here is my component:
JS(Vue):
const Child = createComponent({
setup () {
let tabs = ref()
console.log(tabs)
return {}
},
template: '<div ref="tabs" >Wow</div>'
})Demo: https://jsfiddle.net/xkeyLwu4/2/
However, the value of tabs.value remains undefined. Can someone point out what I might be doing wrong here?
Ensure that your setup() function returns a reference with the same name.
Do not attempt to log the DOM result until after it has been mounted using onMounted.
const Child = createComponent({
setup () {
let tabs = ref()
onMounted(() => console.log(tabs.value))
return { tabs }
},
template: '<div ref="tabs" >Wow</div>'
})
For more examples, refer to the documentation available at:
In order to initialize the ref, it is essential to pass a value to it:
let data = ref([data1, data2, ...])
console.log(data) // The value of data.value has been set to [data1, data2, ...]
