Select2 and initSelection callback

Question

On page load, I\'m trying to use initSelection to select ID 60 (specified value of the input field). I can\'t seem to get it to work properly.

The PHP scrip

Answer 1

Finally solved it! I figured select2 didn't want an array since it's a single value, so I selected the first element of the data.results array.

callback(data.results[0]);

And if you have set multiple:true, just accept the entire results array;

callback(data.results);

Answer 2

You could also use this for less code:

    initSelection: function(element, callback) {
        return $.getJSON("/jQueryScripts/jQuerySelectListArtists.php?id=" + element.val(), null, function(data) {
            return callback(data[0]);
        });
    }

I saw this example in the Select2 wiki, but i had to deal with callback(data) vs callback(data[0]) like you did.
