Hello all,

Have you ever get in situation where you need to convert an user's country iso code to country name. This code is a perfect solution for you. This Javascript function is one of a few Javascript library that I modified and extend it ability to have the capability to produce either country name or country code base on what information being pass into the function. I would like to share this. I love sharing small library function that I wrote.

This function intake a string value. The string value can be a country name or country code. It does not matter on whether if which letter is capitalise or not. What does matter is if the name or the code contain within it's database. For instance if you fetch this function with the word "af", it will spit out "Afghanistan". If you fetch it "afghanistan or Afghanistan or afgHanistan", it will spit out "af".

This function return an array value. Array index 0 is the convert value. If the country name or code is not found in the database it will return an error string. Array index 1 will return the original value that was fetch into the function. This is really great where you want to record what went into the script.


Code:
function getCountryCodeOrName (inputValue) {
var nameCountries = {
'Afghanistan' : 'AF',

Nice one!

How to see its result when running on a browser?

I tried to paste it into a HTML file and wrap around it with this

Code:
<script type="text/javascript">
//your codes
</script>
But it is showing an empty page.

How can I test your code and see it works.
