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).
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,
Quote:
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.
I have an object with a single Method to load content from a xml file. The problem is... how do I add a property to the object to store the data loaded?? I tryed adding a simple Array inside the object, but didn't work.
How do I store an object reference inside a variable when I want the object reference to to reference the first "ul" html element nested inside the current object (as referenced by this keyword)?
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)
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).
Code: if(localStorage) { // Set Item button1 = document.createElement("input");
[Code].....
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.
For a calendar project implemented with pure HTML/CSS/JS I need to access local data files (.ICS). These ICS/iCal data has to be accessed also by other applications (eg. sync, backup, etc).Can anyone point to a possible solution to use HTML5 compatible calls (or jQ plugin) AND how to access the localStorage files also from the other apps.
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?
I am working on a cognos requirement, where we have implemented java script code. The thing is, At the run time, when we give a serial number in a text box and press finish button. The serial number which we gave has to be stored in the text box. Later when the user clicks the "Clear" Button. The serial number text box has to prompt for fresh value.
I am using JavaScript for a web project and I'm using cookies and I have 5 links for different movie trailers and I have a trailers.html page with a div with a id="movie" and want to know so that when you click on a Movie trailer link so that it stores a value in a cookie so that you can check on the trailers page which trailer was chosen and display in the div tag
I have 3 divs in a page, and each div contains a submit button. When the submit button is pressed, i want to process a form contained in that particular div and insert the id of the div into a database in which the submit button was there.So, i want to retrieve the id name of the div and store it in a PHP variable so that i can put it in my sql query. How do i achieve it?
I'm new to using cookies. I am using JavaScript for a web project and I'm using cookies and I have 5 links for different movie trailers and I have a trailers.html page with a div with a id="movie" and want to know so that when you click on a Movie trailer link so that it stores a value in a cookie so that you can check on the trailers page which trailer was chosen and display in the div tag
I am currently in the process of writing an interactive calendar in jscript. It's my first major project so bear with me please, I'm quite new :P.
I was hoping to add a section of code to the calendar which would allow me to display events happening on a certain date and add new ones etc.
However I was not sure how best to store the information as I know javascript is not 'designed' to access files. I was wondering maybe a cookie or learning how to use SQL? Or is there something that I haven't come accross yet?
The purpose of my application is to require a website visitor to complete a form before participating in a search application. I have a specific reason for doing this with client-side javascript, but I'm not going to go into the explanation of "why."
Ideally, the visitor goes to http://www.hopelandinc.com/golf-homes.html. If they haven't registered in 90 days, they'll be redirected to a registration form. Once they complete the reg form, they'll have a cookie set (called "isRegistered") and be taken back to the golf homes page.
For testing purposes, it is not necessary to actually complete the form. You can go to the golf-homes.html page, which will set the regReturn cookie, and then bypass the form submission by going directly to http://hopelandinc.com/registration-thanks.html
In short, it ain't working. (IE 6 test).
golf-homes.html calls the function securePage() below, which sets regReturn and redirects to search-registration.html.
search-registration is a form that posts to an ASP script, then redirects to registration-thanks.html
registration-thanks.html calls the function addRegistrationCookie which adds the isRegisteredCookie, and then redirects to the value stored in regReturn.
I've been trying to figure out why it doesn't work all day, and can't find the problem. Hopefully some super-genius here will be able to help!
Here is the function I'm using to retrieve a cookie value ("regReturn") and redirect to a specified web page:
I'm not sure it's possible that using javascript to locate/get components X|Y then other language, like java-jsp to save/retrive these data.
For instance, a GUI presents a layout of tables/chairs for a exhibition, some small images represent tables/chairs of various sizes/styles, which considered as movable components in this GUI, and their positions specified by X|Y.
regardless of how to connect to database (initially javascript should be able to provide every components' X|Y).
Can any one tell where to find a example, or the idea to implement?
