Custom Events
The following events get triggered on the input element during the life-cycle of a typeahead.
typeahead:active – Fired when the typeahead moves to active state.
typeahead:idle – Fired when the typeahead moves to idle state.
typeahead:open – Fired when the results container is opened.
typeahead:close – Fired when the results container is closed.
typeahead:change – Normalized version of the native change event. Fired when input loses focus and the value has changed since it originally received focus.
typeahead:render – Fired when suggestions are rendered for a dataset. The event handler will be invoked with 4 arguments: the jQuery event object, the suggestions that were rendered, a flag indicating whether the suggestions were fetched asynchronously, and the name of the dataset the rendering occurred in.
typeahead:select – Fired when a suggestion is selected. The event handler will be invoked with 2 arguments: the jQuery event object and the suggestion object that was selected.
typeahead:autocomplete – Fired when a autocompletion occurs. The event handler will be invoked with 2 arguments: the jQuery event object and the suggestion object that was used for autocompletion.
typeahead:cursorchange – Fired when the results container cursor moves. The event handler will be invoked with 2 arguments: the jQuery event object and the suggestion object that was moved to.
typeahead:asyncrequest – Fired when an async request for suggestions is sent. The event handler will be invoked with 3 arguments: the jQuery event object, the current query, and the name of the dataset the async request belongs to.
typeahead:asynccancel – Fired when an async request is cancelled. The event handler will be invoked with 3 arguments: the jQuery event object, the current query, and the name of the dataset the async request belonged to.
typeahead:asyncreceive – Fired when an async request completes. The event handler will be invoked with 3 arguments: the jQuery event object, the current query, and the name of the dataset the async request belongs to.
Example usage:
$(\'.typeahead\').bind(\'typeahead:select\', function(ev, suggestion) {
console.log(\'Selection: \' + suggestion);
});
