188BET靠谱吗To help you get started creating Zotero plugins, we've created a simple Hello World plugin that demonstrates how to access Zotero from an external extension.See188BET靠谱吗Interacting with Zotero from Within Firefoxfor more information.

You can obtain theHello World code from github.

For more information on the basic elements and layout of a Firefox extension, see theXUL School Tutorialin the Mozilla Developer Center.

The most important code is in188BET靠谱吗chrome://helloworldzotero/content/hello.js188BET靠谱吗, which defines a method to insert a new item into the Zotero database and registers a callback function with the Zotero Notifier to receive a notification when an item is modified.The script is loaded by188BET靠谱吗chrome://helloworldzotero/content/include.js, which is included into the main overlay by188BET靠谱吗chrome/content/helloworldzotero/overlay.xul.188BET靠谱吗The latter also adds a menu item to the Zotero Actions menu.

188BET靠谱吗Once installed, the plugin will display an alert whenever an item is added, modified or deleted in Zotero.(You'll probably want your own plugin to do something slightly less annoying.)
