Google chrome扩展程序：本地存储 [英] Google chrome extension: local storage

问题描述

我正在为Google Chrome开发扩展程序，并遇到了一些麻烦。我创建了一个options.html页面，并将其添加到manifest.json文件中。页面显示正确。

I'm developing an extension for Google Chrome, and have run into some trouble.I created an options.html page and added it to the manifest.json file.The page shows properly.

我保存了选项，然后返回到应该运行扩展的页面。

I saved the options, and then went back to the page on which the extension is supposed to run.

不幸的是，本地存储选项是返回一个'null'而不是选项。如果我直接从扩展的JS脚本中设置本地存储选项，它可以正常工作，但如果它是从选项页面设置的，则不会。

Unfortunately, the Local storage for the options was returning a 'null' instead of the option. If I set the local storage option directly from the extension's JS script, it works fine but not if it was set from the options page.

任何想法如何访问options.html我的Javascript文件中的本地存储值是否在扩展名中？

Any idea how i can access the options.html local storage values from my Javascript file in the extension?

推荐答案

have you set them using either:

localStorage["var"]=data;

或

localStorage.var=data;

，您是否使用

and are you loading them using

var myvar = localStorage.var;
