If it's in a string, you can just use:

newstr = oldstr.replace(/,/,".");

For example, head on over to W3Schools and enter:

<html><body>
    <script type="text/javascript">
        var oldstr="8,5";
        var newstr = oldstr.replace(/,/,".");
        document.write(newstr);
    </script>
</body></html>

to get:

8.5

If you want to swap the thousands separators and decimal point, it's a little bit trickier:

<html><body>
    <script type="text/javascript">
        var oldstr="1.472.318,5";
        var newstr = oldstr.replace(/,/,"xyzzy");
        newstr = newstr.replace(/\./g,",");
        newstr = newstr.replace(/xyzzy/,".");
        document.write(newstr);
    </script>
</body></html>

will give you:

1,472,318.5

If you want to intelligently figure out which separator is being used, that's even trickier. What I would do in that case is analyse the string for specific formats. Check how many of each of the . and , characters are and ensure the one with a count of one is treated as the decimal. But that will not work for edge cases like 1,500 - is that fifteen hundred or one point five?

What I would do then is simply put a big message on the web page along the lines of:
