Error message: "The use of Vue 3 refs in the render function is

I am facing an issue with my Vue component wherein the root element is set as ref="divRef". Strangely, when I try to access divRef.value inside the onMounted function, it returns undefined. Any assistance on this matter would be greatly appreciated.

import { defineComponent, onMounted, ref, Ref, h } from "vue"

export default defineComponent({
    setup(props, context) {
        const divRef = ref() as Ref<HTMLElement>

        onMounted(() => {
            console.log(divRef.value) // undefined
        })

        return () => {
            return h(
                "div",
                {
                    ref: "divRef"
                },
                "This is a div"
            )
        }
    }
})

Answer №1

When using the render function, make sure to pass the actual divRef, not just a string representation of it:

return h(
    "div",
    {
        //ref: "divRef"   // AVOID THIS
        ref: divRef
    },
    "This is a div"
)

When trying to access the text within a <code>div

element, it's important to note that div elements do not have a default value attribute. To retrieve the text content, you should utilize the innerText property in the following manner: divRef.innerText.

Update

As per the information provided in the documentation, when working with Vue 3, you must pass the ref itself as the reference in your return element in order to access $el. Your code snippet would look something like this:

return () => {
  return h(
    "div", {
      ref: divRef
    },
    "This is a div"
  )
}

When utilizing JSX in the render function, it is necessary to pass the actual divRef instead of just a string.

set() {
  const divRef = ref() as Ref<HTMLElement>

  return () => <div ref={divRef}></div>
}
