Hi, I've been trying to do something to remove the elements from an array, and I still can not try it for about 2 hours ...
This is a string that is entered by an input text (always of the text form [something], that something can be numbers or letters whatever, that later I transform it into an array with split () and I look for where the first square bracket begins and the second one, then I leave the index of the first square bracket to the index of the second one and add it 1 so that when I delete them with splice, all the elements are deleted between the square brackets including these ones, I commented the code that does not work, I mean the splice, please help!
function rec(nombre) {
//var d = nombre.value;
var get = document.getElementById('nack').value;
var usuario = get; // string
var a = usuario.split(''); // Transformo a array
var b = a.indexOf('[') + 1; // busco el indice del primer corchete
var c = a.indexOf(']'); // busco el indice del segundo corchete
var indices = (c - b) +1; // operacion para sacar los indices
for ( b;b< c; b++) {
document.write(parseInt(a[b]));
// a[b].splice(b, c); <----- No me funciona
}

function rec(nombre) {
var d = nombre.value;
var get = document.getElementById('nack').value;
var usuario = get; // string
var a = usuario.split(''); // Transformo a array
var b = a.indexOf('['); // busco el indice del primer corchete
var c = a.indexOf(']'); // busco el indice del segundo corchete
if (b == -1 && c == -1) {
var indices = (c - b); // operacion para sacar los indices
}
else {
var indices = (c - b) +1; // operacion para sacar los indices
}
var fr = a[indices];
var eliminar = a.splice(b, indices); // elimino
var volver = a.join(''); // vuelvo a convertir en string*/
usuario = volver;
document.write(usuario);

</html> The problem is that I need to delete only the brackets inside that have numbers and then I know how to do it, I tried with typeof a[b] == 'number' and neither, and that's why I think the second one form does not help me in this, since you need a for to go through them, but I do not have any ideas left!
POSTDATA: FOR EXAMPLE IF THERE ARE MORE THAN 1 PARENTESIS WITH NUMEROS OSEA: player [234] [42], which can also eliminate both values and if there are 2 or more but one of them is string, only those with numbers are deleted ie: player [hi] [42], only 42 would be deleted please if anyone knows to help me !!
EXAMPLES FOR BETTER UNDERSTANDING:
1)
Voy y me coloco el nombre "Pepe [soy pro] [42]"
el juego automáticamente me elimina el '[42]' dejando como nombre solamente "Pepe [soy pro]"
2) I go and put the name "Pepe [17] [42]"
el juego automáticamente me elimina el '[42]' y el '[17'] dejando como nombre solamente "Pepe"
