[netmou]

onBlur: function () {
var that = this,
options = that.options;
///////////////////////////////////////////////////////////////////////
if (that.selection == null) {
(options.onInvalidateSelection || $.noop).call(that.element);
}
//////////////////////////////////////////////////////////////////

        // If user clicked on a suggestion, hide() will
        // be canceled, otherwise close suggestions
        that.blurTimeoutId = setTimeout(function () {
            that.hide();
        }, 200);
    },
