解决方案

附加到System.Gadget.Settings.write* 方法，您可以使用System.Gadget.Settings.readString()读回它们.或者，如果您钩上 解决方案

Attach to the System.Gadget.onSettingsClosed event in your main gadget page, and do your reloading there.  If you saved your settings using the System.Gadget.Settings.write* methods, you can read them back with System.Gadget.Settings.readString().  Alternatively, if you hook System.Gadget.onSettingsClosing in your settings page, you can write the values back into your main gadget document using System.Gadget.document.parentWindow.variableName and then reference those variables within the onSettingsClosed handler.  Obviously you'll need to handle the case when the settings dialog was closed by cancelling rather than submitting, but that info is easily available through the event object passed to the events.
