Convert phoenix form name to id with javascript?

Questions & Help Questions
1

If I have the form field name how do I get the corresponding id?

for example

item[a][b][c] → item_a_b_c

does it work in all possible scenarios to just remove ]$, replace ][ with _ and [ with _

name.replace(/]$/, "").replaceAll("][", "_").replaceAll("[", "_")
