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:
Please ensure all amounts are entered in U.S. format (with comma for thousands separator and period for decimal point).
Sometimes you just have to tell the client what's right :-)
