I'm breaking my head with an item that maybe even simple to do but after twelve hours of work the mind does not help ... rsrsrsrs

Friends, I have a query stirng, for example:

&requiredfields=(Vencedor:vencedor).(Categoria:competitividade|Categoria:produtividade)

Where I need to add a new item to it in a specific position. See:

&requiredfields=(Vencedor:vencedor).(Categoria:jovem parceiro|Categoria:competitividade|Categoria:produtividade)

Note that it includes Categoria:jovem parceiro in the query string at the beginning of the parentheses and made a breakdown with | . The position of where this specific character begins I already have, to better contextualize, when items have the same key, they must be inside the same parentheses separated by | , in this way, the position from where it begins - in this example -% how much do i already have I need to move on.

They could help me with this problem. I need to do this with JavaScript. Thanks in advance!

If you already have the position and want to insert text2 into text1, at position X, you can use:

var texto1 = "&requiredfields=(Vencedor:vencedor).(Categoria:competitividade|Categoria:produtividade)"
var texto2 = "Categoria:jovem parceiro|"
var posicao = 37; //Coloque aqui a posição que você já tem
var novotexto = [texto1.slice(0, posicao), texto2, texto1.slice(posicao)].join('');
