Set a locale in javascript

Question

Jquery test the validity of a date via:

!/Invalid|NaN/.test(new Date(value))

new Date(dateString) is the same as Date.parse(dateString) and uses browser/os locale to parse the string.

im trying to parse DD/MM/YYYY but i get an error because my browser is looking for MM/DD/YYYY. Since my product will be used only by DD/MM people, i want to force this behaviour.

I could write a custom validator, but is it possible to change the browser locale via javascript as well?

Answer 1

You can't change the locale, as there is no such feature in the EMCAScript specification.

However, there is a nice package called php.js that implements PHP functions in JavaScript.

Two of the functions are setlocale() and date(). You can use them.

Answer 2

If your product will only be used by DD/MM/YYYY people, set your browser to a DD/MM/YYYY supporting locale.
