问题 I'm building a little locally run CSS driven site map for auditing a huge intranet site. I've already coded the ability, to bring up a context menu which provides for options to make updates to the DOM of index.html. I would like to save these changes to index.html. I know JavaScript doesn't allow manipulation to the client file system, but I've also read in places that it is allowed if the JavaScript is retrieved from the local machine. Can anyone confirm this and point me in the right

问题 There are a couple of different approaches for choosing an HTML5 browser storage (IndexedDB, Web Storage), but from what I read in the spec, the "same origin policy applies".
