I'm thinking in moving from Chosen to Select2 because Select2 has native methods for ajax. Ajax is critical because usualy you have to load a lot of data.
I executed sucessfully the example with the JSON of api.rottentomatoes.com/api/
I did a JSON file to test the ajax, but it didn't works.
I don't know how the JSON should be. It seems that there is no detailed documentation:
https://github.com/ivaynberg/select2/issues/920
I tried unsucessfully several JSON formats, so I tried to copy a JSON format similar to api.rottentomatoes but it doesn't works.
I may be missing something stupid.
function MultiAjaxAutoComplete(element, url) {
$(element).select2({
placeholder: "Search for a movie",
minimumInputLength: 1,
multiple: true,
ajax: {
url: url,
dataType: 'jsonp',
data: function(term, page) {
return {
q: term,
page_limit: 10,
apikey: "z4vbb4bjmgsb7dy33kvux3ea" //my own apikey
};
},
results: function(data, page) {
return {
results: data.movies
};
}
},
formatResult: formatResult,
formatSelection: formatSelection,
/*initSelection: function(element, callback) {
var data = [];
$(element.val().split(",")).each(function(i) {
var item = this.split(':');
data.push({
id: item[0],
title: item[1]
});
});
//$(element).val('');
callback(data);
}*/
});
};
function formatResult(node) {
return '<div>' + node.id + '</div>';
};
function formatSelection(node) {
return node.id;
};
/*MultiAjaxAutoComplete('#e6', 'http://api.rottentomatoes.com/api/public/v1.0/movies.json');*/
MultiAjaxAutoComplete('#e6', 'https://raw.github.com/katio/Quick-i18n/master/test.json');
$('#save').click(function() {
alert($('#e6').val());
});
I did this jsfiddle:

If you switched to JSON make sure you switch dataType to JSON from JSONP.
The format is specified here: http://ivaynberg.github.io/select2/#doc-query
The JSON should look like this:
{results: [choice1, choice2, ...], more: true/false }
Basically the only required attribute in the choice is the id
. if the option contains other child options (such as in case of optgroup-like choices) then those are specified inside the children
attribute.
The default choice and selection renderer expect a text
attribute in every choice - that's what is used to render the choice.
so a complete example of a US state using default renderer might look like this:
{
"results": [
{
"id": "CA",
"text": "California"
},
{
"id": "CO",
"text": "Colarado"
}
],
"more": false
}
Hope this gets you started.
