Local Storage is a wonderful resource that is fundamental to the working of web pages, even more so in the case of browser apps. Without this type of memory being attached to the browsers, many aspects of programming would be impossible. Without it, there would be no webprog3 for example! If you need to pass information from one browser window/tab to another, using Local Storage to save and retrieve it is the only practical method I know of. (That is, providing the pages involved reside on the same domain, or in the case of offline apps, reside in the same HD folder.)
I have already outlined the simple usage of Local Storage via Javascript/JQuery here in the FULL HELP section.
At the time of writing I was a bit worried about questions of memory capacity, but the moment I significantly increased my Firefox's domain Storage Default Quota, things ran smoothly, and I have never looked back. (See HERE for how to do this - it's very simple.)
Take a look at this app at WP3's brother website howsoft.com:
All well and good.
However, the reason I have brought up the topic of Local Storage here is because it has a limitation which is a bit of a bummer!
As well as designing web pages for use on the Internet, I am also interested in producing offline browser apps. The "howText" app you see in this section of the site is an example of one. In its development, I ran up against a problem. I wanted it to run on both Firefox and Google Chrome, at least. And therein lies the rub!
FIREFOX WILL NOT ALLOW YOU TO USE Local Storage OFFLINE!
Since I normally use Local Storage to pass information to my printing modules, I was stuck!
But as you might have already seen, I managed to solve the problem with a technique that I was unfamiliar with previously. We shall be going into the details of this when I discuss the "howText" app a little later on. OK?
