I want to convert the following PHP code to JavaScript, This is an array of key/value pairs in PHP:
PHP code:
$countries = array("AF"=>"AFGHANISTAN","AX"=>"ALAND ISLANDS");
What's the best way to do this in jQuery or JavaScript?
-
1Note also that jQuery IS JavaScript, so there is no such thing as a jQuery array, only a JS array.Mitya– Mitya2012-08-22 10:23:19 +00:00Commented Aug 22, 2012 at 10:23

javascript doesn't have an associative array (like in PHP, your example above), instead, we call it javascript object:
var countries = {
'AF': 'AFGHANISTAN',
'AX': 'ALAND ISLANDS'
};
Comments
var countries = {
"AF": "AFGHANISTAN",
"AX": "ALAND ISLANDS"
}
Then, to get the value for a given key, use one of the following:
var af = countries["AF"];
var ax = countries.AF;

Use json_encode():
<script>
var countries = <?php echo json_encode($countries); ?>;
</script>
That's what will be stored in countries:
{
AF : "AFGHANISTAN",
AX : "ALAND ISLANDS"
}
If you just want to reproduce such a data structure in JS, use objects as stated in the other posts.

Sorry but the edit changes the meaning of my original answer, and makes not much sense at all - no strings are involved at all, I just go from PHP array to JS object.
