问到_destroy()还是销毁()？

EN

// Use the destroy method to clean up any modifications your widget has made to the DOM
destroy: function() {
  // In jQuery UI 1.8, you must invoke the destroy method from the base widget
  $.Widget.prototype.destroy.call( this );
  // In jQuery UI 1.9 and above, you would define _destroy instead of destroy and not call the base method
}

$.widget( "demo.widget", {
    destroy: function() {
        // Invoke the base destroy method
        $.Widget.prototype.destroy.call( this );
        // Perform widget-specific cleanup
        ...
    }
});

$.widget( "demo.widget", {
    _destroy: function() {
        // Perform widget-specific cleanup
        ...
    }
});
