If I have a text string such that:
var cadena1 = "cadena_1";
And I just need to get 1 from the previous string to put it in a variable, how can I do it?
Doing this:
var res = cadena1.split("_");
the result is cadena,1

var res = cadena1.split("_");

it would be enough to do:
var res = cadena1.split('_')[1]; // segundo elemento del array que se obtiene al hacer split

You can use split() by taking the second element:
var cadena1 = "cadena_1";
var res = cadena1.split("_")[1];
console.log(res); Or use substring() if you know that there will only be 1 number. With the possibility of values > 9 would use the option of split()
var cadena1 = "cadena_1";
var res = cadena1.substring(cadena1.length-1);
console.log(res);Just use split ()
var tmp = cadena1.split("_"); //retorna un array
//console.log(tmp);
var num = tmp[1];
console.log(num);
