Storing Objects in HTML5 localStorage
I'd like to store a JavaScript object in HTML5 localStorage, but my object is apparently being converted to a string.

HTML5 localStorage for assets (stylesheets, JavaScript, images etc)
To save both client download time and network usage, is it possible to use the localStorage feature of HTML5 to store contents of linked stylesheets, javascript files and binary data (e.g. images), rather than hitting the server each time? Would that just complicate things - since I assume you would have to add the linked asset via Java...
Opera localStorage ignores my existence check

Local development using HTML5 storage
I am experimenting with HTML5 local storage functionality, but was frustrated to learn that the browser won't allow local storage when the file is local. My guess is that the browser (Chrome in my case, FF too) wants to see a domain rather than a file location. Has anyone here discovered a workaround for developing locally? Perhaps setti...
HTML5 on iPhone Safari - data stored by localStorage does not always persist. Why?
Hi, I write a simple iPhone web app using HTML5's localStorage.

Do all the HTML5 storage systems work together ?
While there are a lot of good stuff about html5, one thing I don't get is the redondant storage mechanism, first there is localstorage and sessionstorage, which are key value stores, one is for one instance of the app ("one tab"), and the other works for all the instances of that application so they can share data. Both are saved when yo...

How do I include 2 tables in one LocalStorage item?
I've got a table that you can edit, and I've got a simple code saving that list when you're done with editing it. (the tables have the contenteditable on) The problem I've stumbled upon is that if I double click on enter, the table gets divided into two separate tables with the same ID. This causes the code I'm using to set the localSt...
HTML5 localStorage restrictions and limits
HTML5's localStorage databases are usually size-limited — standard sizes are 5 or 10 MB per domain. Can these limits be circumvented by subdomains (e.g. example.com, hack1.example.com and hack2.example.com all have their own 5 MB databases)? And is there anything in the standard that specifies whether parent domains can access their chil...

One value refuses to save, and I can not for the life of me determine why. The following problem c...
