javascript - Why does a function in the form [string](a,b,c){...} report an error?

Question

I want to implement a tab and call the corresponding interface (already packaged) based on the value of the tabIndex passed in

But an error occurred:

Is this way of writing wrong?

Answer 1

this[getData]

Answer 2

However, I thought of a way, first write the function into methods, and then use this[getData] and it works
