Try parseInt()
parseInt(s)
parseInt(s, radix)
arguments:
s = The String to be passed.
radix = An optional integer argument that represents the radix (i.e., base) of the number to be passed.
For more information refer to "Javascript - The Definitive Guide" page 643 in the 3rd edition.

You would use the function: Number()
<SCRIPT LANGUAGE="JavaScript">
<!--
v = "32";
document.write(v + 1 + "<BR>"); // Ouputs 321
document.write(Number(v) + 1 + "<BR>"); // Outputs 33
//-->
</SCRIPT> - tleish

<!--
v = "32";
document.write(v + 1 + "<BR>"); // Ouputs 321
document.write(Number(v) + 1 + "<BR>"); // Outputs 33

</SCRIPT> - tleish
