I would like to make an array containing strings in this format:
[Texto com acento espaço e números 99]
Example, if I have this string:
var texto = "Eu quero comprar [qtdOvos] e [qtdFrutas] somando o total de [totalCompras]";
I need to mount the following array:
var arrayStrings = ["[qtdOvos]", "[qtdFrutas]", "[totalCompras]";
Is there any way to do this through regular expression?
Yes, it is possible. You can use: .match(/(\[\w+\])/g) .
In this case you have to "escape" the [ because they are reserved in Regex. You create a capturing group with () , you use \w+ to say that it is a letter or number and g to say that it is recurring.
If you want to "catch" everything within [] more comprehensively you can use /(\[.*?\])/g .
You can do this:
var texto = "Eu quero comprar [qtdOvos] e [qtdFrutas] somando o total de [totalCompras]";
var arrayStrings = texto.match(/\[[A-Za-z0-9]+\]/gi);
arrayStrings will contain exactly what you want:
["[qtdOvos]", "[qtdFrutas]", "[totalCompras]"]
Another expression that can be used is /\[(?:.*?)\]/ which will correspond to everything that is between [ and ] .
var texto = "Eu quero comprar [qtdOvós] e [qtdFrutâs] somando o total de [total Comprãs]";
var array = texto.match(/\[(?:.*?)\]/g);
// [qtdOvós],[qtdFrutâs],[total Comprãs]
