When using this.$refs in Vue, be mindful that the object may be undefined

After switching to TypeScript, I encountered errors in some of my code related to:

Object is possibly 'undefined'

The version of TypeScript being used is 3.2.1

Below is the problematic code snippet:

this.$refs[`stud-copy-${index}`][0].innerHTML = 'Link Copied'

I attempted to handle the issue by adding an if condition to check for undefined values, but it did not solve the problem:

if (this.$refs[`stud-copy-${index}`] !== undefined) {
  this.$refs[`stud-copy-${index}`][0].innerHTML = 'Link Copied'
}

Answer №1

Would you please give this a shot?

(this.$refs[`stud-copy-${index}`] as HTMLElement[])[0].innerHTML = 'Link Copied'
