Yeah, you're kind of all over the place with that code. Try this
(note the comments):
$("#load_abbr_data").click(function()
{
var abbrs = {}; // hash
$.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;
// add to hash
abbrs[abbr] = desc;
});
// still inside getJSON callback, dump output
// by iterating all properties of abbrs hash
for (var a in abbrs)
{
// 'a' is the current property we're iterating
document.write(a + " is short for " + abbrs[a]);
}
});
});
