Good evening, I have a question, I need to enter a number in javascript print it in the console for the amount entered. For example if you want the string to be an asterisk "*": If I enter a number 5, the result should be: *****.
Something that works like this: 5 * "*" = *****
The str.repeat method will do that for you:
var str = "Hello world!";
str.repeat(2);
Result: Hello world! Hello world!
If you want to multiply numbers it will simply be like a normal multiplication
A workaround very used in your case is to use the join method of the Array object:
function calcularResultado(){
var caracter = $('#caracter').val();
var repeticiones = parseInt($('#repeticiones').val());
if (caracter.length!==1 || isNaN(repeticiones)) {
$('#resultado').text = '';
return;
}
$('#resultado').text(Array(repeticiones + 1).join(caracter));
}
$(function(){
$('#caracter').on('keyup', calcularResultado);
$('#repeticiones').on('keyup', calcularResultado);
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Carácter: <input id="caracter" type="text" maxlength="1" placeholder="Introduce carácter" /><br /><br />
Número: <input id="repeticiones" type="number" placeholder="Nº de repeticiones" /><br /><br />
<div id="resultado"></div>I hope this serves you. Greetings.
function Concatenar_String(A_Repetir, Num_Veces)
{
for(var i = 0; i < Num_Veces; i ++)
{
Valor_Final += A_Repetir;
}
return Valor_Final;
}
