使用Greasemonkey脚本跨域本地存储 [英] Local storage across domains using a Greasemonkey script

问题描述

是否可以使用Greasemonkey脚本跨域存储数据?我想允许从使用相同Greasemonkey脚本的多个网站访问Javascript对象.

Is it possible to store data across domains using a Greasemonkey script? I want to allow a Javascript object to be accessed from multiple websites that are using the same Greasemonkey script.

推荐答案

是的，这是 GM_setvalue() ，它可以按域每个脚本存储数据.

Yes, that is one of the purposes of GM_setvalue(), it stores data, per script, and across domains.

请注意，沼泽标准GM_setValue()有点问题.它可能会使用大量的全局资源或导致脚本实例崩溃.

Beware that the bog-standard GM_setValue() is somewhat problematic. It can use lots of global resources or cause a script instance to crash.

以下是一些准则:

1. 请勿使用GM_setValue()来存储字符串以外的任何内容.除此之外，请使用诸如 GM_SuperValue 之类的序列化程序.甚至看起来无辜的整数也可能导致默认的GM_setValue()崩溃.

1. Do not use GM_setValue() to store anything but strings. For anything else, use a serializer such as GM_SuperValue. Even innocent looking integers can cause the default GM_setValue() to crash.

与其存储许多小变量相比，不如将它们包装在一个对象中并用一个序列化器存储起来更好.

Rather than store lots of small variables, it may be better to wrap them in an object and store that with one of the serializers.

最后请注意， localStorage 在javascript中具有特定含义，而localStorage 是 特定于域的.

Finally note that localStorage has a specific meaning in javascript, and localStorage is domain specific.
