Good night

in the example below add up if the values of 3 text boxes, and the result comes out in the fourth, how to make this result appear with comma and not with dot?

<html>
<head>
<script type="text/javascript">
function id( el ){
        return document.getElementById( el );
}
function getMoney( el ){
        var money = id( el ).value.replace(/[^0-9]/g,'');
        return parseFloat( money );
}
function soma()
{
        var total = getMoney('campo1')+getMoney('campo2')+getMoney('campo3');
        id('campo4').value = 'R$ '+total/100;
}
</script>
</head>
<body>
        <form action="" method="">
                <input name="campo1" id="campo1" value="25,60" /><br />
                <input name="campo2" id="campo2" value="5,15" /><br />
                <input name="campo3" id="campo3" value="2,63" /><br />
                <input name="campo4" readonly="readonly" id="campo4" /><br />
                <input type="button" onclick="soma()" value="Soma de Valores" />
        </form>
</body>
</html>

    There’s another question and his excellent answers regarding how to treat money in JS, take a look there. The simple/minimalist answer to your question would be id('campo4').value = 'R$ ' + (total/100).toString().replace('.', ',');.

    Vitor, I think that that answer is simpler for your doubt. But advice see the one that @Sergio tagged as duplicate, is much more complete.

  • cool, but where do I find this answer?

  • @Vitormarqueslourenço I gave you the answer in the first comment. And if you read the other question and answer you will know how to answer in even more detail.

With the toLocaleString() Javascript can have this adapted depending on the locale:

22.33.toLocaleString(); /* depende do locale */
"22,33"

Or use a default, for example:

22.33.toLocaleString('EN');
"22.33"
22.33.toLocaleString('PT');
"22,33"
