如何实现一个命令，所以当firefox-addon被卸载时执行？

问题描述

我使用附加SDK创建了一个Firefox插件。

我的脚本增加了一些东西给firefox，这在这里没关系。如何实现在卸载和禁用时调用的函数的步骤？

我读了，，和和。

所以，在 main.js ;

  exports.onUnload = function（reason）{
 //在附加元件被调用时调用
 //卸载
 //禁用
 //关闭
 //升级
 //降级
}; 
  

I created a Firefox add-on with the Add-on SDK.

My script adds something to firefox, which doesn't matter here. How are the steps to implement a function that is called on uninstall and on disabling?

I read this Code Samples article, this, this and this manual and this Answer, but didn't manage it, it doesn't seem to work or I am lacking of information where to add this and what else I have to program around it.

Also the manual seems to be outdated, cause When I add code from there and compile it with:

cfx xpi

I get warnings, that I should use const {Cu} = require("chrome"); instead of the Components Object - Which i did then and compiled without error, but still, I couldnt get a command to be executed on uninstall yet.

Do I need to write it all in the main.js file? Or do I need an extra unistall file that is called?

Can you give a running example on how to implement this?

解决方案

In main.js, use exports.onUnload.

So, in main.js;

exports.onUnload = function(reason) {
    //called when add-on is 
    //    uninstalled
    //    disabled
    //    shutdown
    //    upgraded
    //    downgraded
};
