I switched to typescript and suddenly some of my codes are having errors with:
Object is possibly 'undefined'
The typescript version is 3.2.1
Here's the code:
this.$refs[`stud-copy-${index}`][0].innerHTML = 'Link Copied'
I've tried to add an if condition to check if it's undefined but no luck:
if (this.$refs[`stud-copy-${index}`] !== undefined) {
this.$refs[`stud-copy-${index}`][0].innerHTML = 'Link Copied'
}
CodePudding user response:
Can you try this
(this.$refs[`stud-copy-${index}`] as HTMLElement[])[0].innerHTML = 'Link Copied'
