LocalStorage And SessionStorage Aimed At Mobile Browsing?

Oct 14, 2010

I've recently written a small javascript library that creates a unified interface for localStorage and sessionStorage.

The code is here[URL]... I'm looking for people to give me feedback and to help me work on it should you so wish.

JQuery :: Wrap-like Method Aimed At Attributes?

Sep 11, 2011

This is probably wishful thinking, but I'm wondering if there is an elegant way to take an array of strings and "wrap" each of them into becoming the value of a particular attribute in an html tag? The particular option is form-building; I have a bunch of options a,b,c and need to build <input type=checkbox value=a>, value=b, value=c, etc. I know I can do it by iterating. But I'm wishing for something like the "wrap" method that would let me wrap the input tag around each possible value of the attribute. Does that exist?

Browsing For Files From A Browser?

Jan 20, 2010

I have a tabular html form where users can enter a number of titles and file specifications in columns. Having the users actually ENTER the full filespec (path AND filename) has proven problematic so I'd like to give them a way to browse around the local system on which the browser is running, and select the file. When done, they hit Submit and the filespec get sent to php along with everything else on the form.....

So far I've gotten lots of "you can't do that" (I stupidly thought the input type="file" would actually work), and found a few javascript samples that MIGHT do it if I could get any of them to work. I CAN'T be the first person ever to need a way for users to do this to upload or email files or whatever. I"m sure I'm missing something important, but I'm astonished there isn't a reasonable way to do this in html.

First, CAN THIS be done in javascript - Display the form. Show any previously entered values in the fields. Let the user change existing filespecs, enter new filespecs, or browse the system to select filespecs. Put whatever they select in the field. When they hit submit send the filespec (the WHOLE filespec) along with the other data back to php for storage?

If so, does anyone have a pointer to a good, simple, idiot-proof example? Unfortunately, at this time I know VERY little about javascript, so I need something that can be understood and quickly implemented...

Error Firefox Using LocalStorage

Jul 12, 2010

So i am working on a piece that using local storage and saves them to an un ordered list. I have been using Chrome for the console and inspector abilities and it has been going well. I've tested it before in Safari and Opera and I know it works. However, in Firefox (and IE but I don't care about that) I am getting a console error.

Here is the code being executed:

There is some jQuery thrown in there but basically it says, test for a localStorage key of i, if it is not null create the list item, add one to i and repeat.

I am getting the following error in firefox only:

Index or size is negative or greater than the allowed amount" code: "1 [Break on this error] while (localStorage.key(i) != null)

Way To Store An OBJECT In LocalStorage?

Mar 21, 2011

I've been experimenting with Local Storage. I can do things like this just fine:

But if I do this:

...then place it in local storage, reading it back gives me a TEXT STRING that says "[Object object]" and not the actual object.

I would like to be able to store multiple values in one object, but it doesn't seem to work.

I also tried to store a variable obtained with "document.getElementById" and when read back it just says [HTMLDivElement] (something like that) instead of the actual element.

Am I doing something wrong, or does local storage not support objects? (btw, tested on FF 3.6).

JQuery :: What Are The Latest Versions Of Jquery.mobile-min.js And Jquery.mobile-min.css

Jan 11, 2012

For my Dreamweaver program I want to update to the latest version so I can build within it, but I'm confused as to what are the latest versions of jquery.mobile-min.js and jquery.mobile-min.css. The site has 1.0 as the latest stable build. But Dreamweaver's third-party folder (the place that houses jQuery mobile scripts) has 1.0a3 for the css and 1.5 for the mobile.min file. I was told by Adobe that they do not update jQuery scripts when updating their program. I think that's a mistake, myself. Whether it is or not, it sure would be useful now.

LocalStorage: Cannot Get Storage Event To Fire

Jun 7, 2011

I'm attempting to track changes to values I've stored in the localStorage object. From everything thing I've read, this is done by adding a "storage" event listener to the window object but the test file I made doesn't seem to fire the event. I was under the impression that there was pretty good support for this (although I do realize the spec is still under revision).

if(localStorage) {
// Set Item
button1 = document.createElement("input");


I create two buttons on the page - the first to write a value to localStorage (which works) and the second to clear all values from localStorage (also works). The problem is the event just does not want to fire for me. Even if I set the event on the window's "onstorage" property rather than use addEventListener, no event fires. I've tried in the most recent Chrome, Firefox and Safari browsers.

localStorage.setItem("artist-2", "2");
localStorage.setItem("artist-3", "3");

Password Protected HTHL5 LocalStorage Security?

Apr 21, 2011

I've just started my venture into HTML5 localStorage. I now have a javascript my server sends to those who visit my ip address. I store all their data using localStorage. I have a few security questions regarding the HTML5 localStorage situation:

1. Can a script that did not create the local storage retrieve/modify the localStorage of another script just by guessing the key maliciously or unintentionally?

2. Can another script use the clear() method to remove my scripts data? Edit: I just tried this myself. And, yes, I deleted my data, all of it with clear() using a different script. Is there any way to prevent this? Is it only my end that will be able to do it or could I load a script from a site has a hidden clear() method and destory all other javascript apps data?

3. If item (2) is true, any ideas on how to protect my scripts data for the user from the clear method?

4. if item (2) is false, cool, my first idea is to create a uniqnue string random string and ask the user to creat a password to encrpt that string and just use that string with enumeration added to it for the keys.

5. Does anyone know where localData is stored? Is it encrypted already, in plain text, in well-known or hidden location?

Using LocalStorage To Store A Large Amount Of Data - > 5mb

Dec 13, 2011

I've been using localStorage to store a large amount of data (> 5mb). I know that most browsers limit localStorage to 5mb. However, on the specification site it states,


User agents may prompt the user when quotas are reached, allowing the user to grant a site more space. This enables sites to store many user-created documents on the user's computer, for instance.

Is this available yet? If so, how would I use it?

AJAX :: Cross-browsing Request Work Around - Every Browser Doesn't Work ?

Jun 14, 2010

The "Permission denied" cross site issue.

I have to check from my external domain if a service is running on localhost:8080 of a local machine.

I'm using XMLHttpRequest to do it.

I'm checking a local-web-server, not a file.

Every browser doesn't work, but Firefox. So I'm looking for a work-aorund.

An iframe? a flash swf? an applet java? HTA applications?

A side question is, why does FF work? Because it's a local-web-server?

JQuery :: When Click On The Gallery Thumb It Should Open The First Photo In Fancybox And Browsing Through The Gallery Should By Peanuts?

May 2, 2011

I've found a post regarding this issue but it's a little bit different this time.So I've created a .php script which creates some galleries where users can click them and browse their respective photos. It works like a charm in Chrome and FireFox, but IE doesn't like it.With this code:



When I click on the gallery thumb it should open the first photo in fancybox and browsing through the gallery should by peanuts. And it is, but with IE just opens the .jpg in a blank page without fancybox. The strange thing is I've used the same script approach in another website and the fancybox works just fine with IE too. So why doesn't in this case?

JQuery :: Scrolling On Mobile Safari

May 25, 2010

I'm developing a website and I need the browser to scroll to an anchor. It MUST be animated, so I tried to use jQuery for that. Tried this:

function goToByScroll(id){
$('html,body').animate({scrollTop: $("#"+id).offset().top},'slow');

It works perfectly on Firefox and Safari(on the Mac). On Mobile Safari it first goes to the top of the page, then it scrolls to the anchor I want it to scroll to. What's the trick to make it work?
