如何/在哪里存储数据在Chrome Tampermonkey脚本中? [英] How/Where to store data in a Chrome Tampermonkey script?
问题描述
localStorage
。这工作正常。但我注意到,几个小时后,我存储的所有数据都被删除了automagicllay。 Facebook本身可能会删除所有localStorage数据。
现在,我搜索了替代品。
- Cookie :否用户清除历史记录后将删除。
- 网络SQL :显然它被w3.org丢弃了。所以在不久的将来,我认为chrome可能不会使用web sql。
我想将数据存储在客户端系统中。我有什么选择?我应该使用FileSystem来存储数据吗?
由于您使用的是 Tampermonkey (Chrome)和Greasemonkey(Firefox)。继续使用 GM_setValue()
。它不能被Facebook或任何其他网站清除。
它具有跨域存储值的优势。
~~~
请注意, Firefox 中的标准 GM_setValue() 。它可能导致脚本实例在无效值上崩溃 - 因此最好使用序列化程序,例如 GM_SuperValue ,用于存储除字符串以外的任何内容。即使天真无邪的整数可能导致默认的 GM_setValue()
崩溃。
目前,只有 GM_setValue()
,Cookie,localStorage和 IndexedDB 可用于持久数据浏览器。
IndexedDB也可能做你想做的事,但它不如 GM_setValue()
。
更新:
如今,别忘了使用:
-
// @grant GM_setValue
和 -
// @grant GM_getValue
另外,如果你请使用GM_SuperValue库,现在将它添加到:
// @require http://userscripts-mirror.org /scripts/source/107941.user.js
在元数据块中。 (因为userscripts.org已经很长时间了。)
I wrote one Greasemonkey/Tampermonkey script for Facebook . I needed to store data to retrieve it later. For that I used localStorage
.
That was working fine. But I noticed that after few hours all data which I stored was removed automagicllay. Probably Facebook itself deletes all localStorage data.
Now, I searched for alternatives.
- Cookies : No this will be removed when user clears history.
- Web SQL : Apparently it is dropped by w3.org. So in near future I assume chrome might not be using web sql too.
I want to store the data in client system. What option do I have? Should I use FileSystem to store data?
Since you are using Tampermonkey (Chrome) and Greasemonkey (Firefox). Go ahead and use GM_setValue()
. It cannot be cleared by Facebook or by any other website.
It has the advantage of storing values cross-domain, as well.
~~~
Beware that the bog-standard GM_setValue()
is somewhat problematic on Firefox. It can cause a script instance to crash on invalid values -- So it's best to use a serializer, such as GM_SuperValue, to store anything but strings. Even innocent-looking integers can cause the default GM_setValue()
to crash.
Currently, only GM_setValue()
, cookies, localStorage, and IndexedDB are available for persistent data on both browsers.
IndexedDB would also probably do what you want, but it is nowhere as easy to use as GM_setValue()
.
Update:
Nowadays, don't forget to use:
// @grant GM_setValue
and// @grant GM_getValue
Also, if you do use the GM_SuperValue library, you would now add it with:
// @require http://userscripts-mirror.org/scripts/source/107941.user.js
in the metadata block. (Since userscripts.org is long dead.)
