Make the jQuery UI Autocomplete widget appear on blur, not keypress.

jquery-autocomplete-blur.js

/*
 * Use the small setup below to make the
 * jQuery Autocomplete widget show on input-blur,
 * rather than on every keypress.
 */
(function ($) {
    
var field = $('.selector');

field.autocomplete({
    
    select: function (e, ui) {
        // Make sure the input has its value set properly
        field.val(ui.item.value);
    },
    
    change: function (e, ui) {
        // This prevents the autocomplete from showing straight after selecting a response
        if (typeof(ui.item) === 'undefined' || ui.item.value !== field.val()) {
            field.autocomplete('search');
        }
    }
        
}).unbind('keypress keydown input focus'); // Remove unwanted events

}(jQuery));
