I have five digit US zip codes coming out of the database. When JavaScript see them, it treats them as a number and lops off the leading zeros.
How do I get JavaScript to treat the numbers as a string so that they display correctly?

Quote them.
In both JavaScript and JSON
05123is an octal number equal to2643(thanks @Marc B) and"05123"is a string containing only numeric characters.Don’t quote them in your database, of course. You’ll want to quote them in the JavaScript or JSON you are generating in the server-side code that’s reading the information from the database and passing it to your client-side code. Ordinarily, that’s as simple as casting the zip code to a string (or, as is the more likely case, not casting your numeric zips to a number.)
