如何向 Firefox 插件添加循环计时器？

发布于 2024-10-20 22:47:51 字数 661 浏览 5 评论 0原文

我正在尝试使用新的插件构建器预览 (https://builder.addons.mozilla.org/) 创建一个插件，并且我需要一个大约每 10 分钟运行一次的函数。我尝试过 setInterval 和 setTimeout，但它们都返回以下错误：（

    error: An exception occurred.
Traceback (most recent call last):
  File "resource://jid0-31njasqk3btmpa6paroepuybjn4-myaddon-lib/main.js", line 41, in 
    setTimeout(function() { timedCount(); }, 10000);
ReferenceError: setTimeout is not defined

当我尝试时，setTimeout 被 setInterval 替换。setTimeout 函数在我构建的类似网页中工作得很好。我只是让函数调用本身给出无限循环（听起来很愚蠢，应该有一个 while 循环，但它是在教程中；）但现在我无法克服插件中的错误。

另外，如果你可以帮助我解析这个插件中的本地或远程页面（最好是远程的，但我可以让它解析本地主机上的 django 创建的页面），或者更好，只需告诉我如何使用 python ;)会很棒的。

谢谢！

I am trying to create an addon with the new addons builder preview (https://builder.addons.mozilla.org/), and I need a function to run about once every 10 minutes. I have tried both setInterval and setTimeout, but they both return the following error:

    error: An exception occurred.
Traceback (most recent call last):
  File "resource://jid0-31njasqk3btmpa6paroepuybjn4-myaddon-lib/main.js", line 41, in 
    setTimeout(function() { timedCount(); }, 10000);
ReferenceError: setTimeout is not defined

(with setTimeout being replaced with setInterval when I tried it. The setTimeout function worked great in the similar webpage that I built. I just had the function call itself to give an infinite loop (It sounds stupid, there should be a while loop, but it was in a tutorial;)
But now I can't get past that error in my addon.

Also, if you can help me parse a local or remote page in this addon (preferably remote, but I could make it parse a django-created page on localhost instead), or even better, just tell me how to use python ;) that would be great.

Thanks!

请注意，上面的内容已被弃用

var tmr = require('sdk/timers');

，现在已使用

please note that the above is deprecated

var tmr = require('sdk/timers');

is now used instead

使用计时器模块：

var tmr = require('timer');
tmr.setInterval(timedCount, 10000); // no need for an anon function since you don't pass any arguments to your function nor capture anything in a closure

Use the timer module:

var tmr = require('timer');
tmr.setInterval(timedCount, 10000); // no need for an anon function since you don't pass any arguments to your function nor capture anything in a closure
