If you want to only get the first number/decimal in the string, you can use the following:

<script type="text/javascript">
var str = "ABC12g345";
str = parseFloat(str.replace(/^\D+/,""));
alert(str);
</script>

The regular expression will strip out any non-numbers in the beginning of the string, and then take the numbers left at the beginning.  Hope one of the two helps.
