  • 772

If I have a text string like so:

var cadena1 = "cadena_1";

And I only need to get the 1 from the previous string to put it in a variable, how can I do it?

Doing this:

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

the result iscadena,1

javascript

    it would suffice to do:

    var res = cadena1.split('_')[1]; // segundo elemento del array que se obtiene al hacer split

  2. You can use split()grabbing the second element:

    var cadena1 = "cadena_1";
var res = cadena1.split("_")[1];
console.log(res);

    Or use substring()if you know there will only be 1 number. With the possibility of values > 9​​I would use the option ofsplit()

    var cadena1 = "cadena_1";
var res = cadena1.substring(cadena1.length-1);
console.log(res);

  3. Just use split()

    var tmp = cadena1.split("_"); //retorna un array
//console.log(tmp);
var num = tmp[1];
console.log(num);
