[jQuery] Json help adding into Object

[jQuery] Json help adding into Object


I have some code that I need help with. I have a database with a list
of abbreviations with is encoded into JSON in a PHP script, the script
below pulls in that data and stores the data as objects (or thats how
I want it to be).
$("#load_abbr_data").click(function()
{
var abbrs = {}
    $.getJSON("jsondata.php",function(data)
        {
            $.each(data.abbr_data, function(i,get_abbr_data)
            {
                var abbr = get_abbr_data.ABBR;
                var desc = get_abbr_data.DESCRIPTION;
                var lang = get_abbr_data.LANG;
                abbrs =
                {
                    abbr : [desc],
                }
            });
        });
});
So I would like the resulting object to look like:
var abbrs =
{
HTML : [ 'HyperText Markup Language']
, PHP: 'Personal Home Page'
}
But I don't think it does (or at least it only saves the last record).
And have this script run:
var somevar = "PHP";
    for( var i = 0 ; i < abbrs[somevar].length; i++)
    {
        var expanded = abbrs[somevar];
    }
alert( somevar + " is short for " + expanded );
But the problem is I can't get it to save as the example object. And
when I run the above script nothing works. Could I please have some
help in getting the JSON script working please.
