Efficient regex for Canadian postal code function

Question

var regex = /[A-Za-z]\\d[A-Za-z] ?\\d[A-Za-z]\\d/;
var match = regex.exec(value);
if (match){
    if ( (value.indexOf(\"-\") !== -1 || value.indexOf(\" \") !== -1 )          


        

Answer 1

regex = new RegExp(/^[ABCEGHJ-NPRSTVXY]\d[ABCEGHJ-NPRSTV-Z][-]?\d[ABCEGHJ-NPRSTV-Z]\d$/i);
if(regex.test(value))
    return true;
else
    return false;

This is a shorter version of the original problem, where value is any text value. Furthermore, there is no need to test for value length.
