I am trying to use jQuery AJAX. What my requirement is, i wish to load user names from DB in dataset, convert it to JSON format and store it in memory or using jQuery data for use while a user is browsing my site, i.e for a session. This way I can use autocomplete or my own code to display data to user.
View 1 RepliesMy table is a data table, and I'm contemplating using it as the data store as well, rather than keep a js array of data separately. The cell values are retrieved by ajax, then inserted into the table. I'm thinking that the duplication of data (once in the js array, once in the table) is likely to lead to strange results somewhere along the line, where the two data sets get out of synch. It seems to me that jquery makes using a table in this way rather simple (I refer to the jquery selectors in particular). The table includes some editable-in-place columns.
If any such edits, and user presses a Save button above the table, the save function finds the edited fields and sends an appropriate ajax call, then refreshes the table with the outcome (eg it worked, so new values remain shown, it didn't work, revert, or something like that, it's not too important here). Hence the need to maintain some 'awareness' of the values in the cells. I'm content with using attributes as needed to support this (e.g., to be able to revert to original value, to mark cells that have been edited). Table may contain up to 500 rows, ten columns. How it compares with keeping the data in a js array?

View 1 Replies View RelatedI wanted to define additional attribute to a tag to manage information. I realized that XHTML might not like it and discovered the data(name,value) function. I was wondering how I could retrieve all tags e.g. "div" that have that data variable set.

I have a project that I need to read some data from an XML file.
Something like:
However, since JS is a client side script so it can't read from client side, is there any alternate way to do this? I am thinking to create a "Data" class, and many "Data" objects, is this an elegant way to do it?

I've gone back and forth on the best way to store data in HTML elements which is used to support JavaScript. For instance, I might have a bunch of rows each associated with a SQL ID, and upon clicking the delete element, want to grab the id, and send it to the server. I've successfully used the following three solutions, but would like to standardize on just the best.
Option 1 is technically valid, but seems excessive. Option 2 will work fine, but is considered by some as bad practice. Option 3 requires the extra step of splitting the ID from some identifier string, and care not to have the same record twice on the page.

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.
Is this available yet? If so, how would I use it?
I want to be able to send data store in JavaScript variable to my email account.
I have tried using mailto: command and for some reason it doesn't work.
Lets say I wanted store a long string of text into a local storage member on a browser using javascript.
window.localStorage.setItem("key",longStringText);
Now lets assume that the text itself contains characters outside of the normal ISO-8859-1 character set (like asian or russian characters). Would the individual char values be stored as one byte or two bytes?
"hello" -> 5 * 1 bytes = 5 (normal 8859 character sets)
"hello" -> 5 * 2 bytes = 10 (unicode or an extended character set size).
Is ISO-8859-1 still stored like ASCII once was as 8 bits? Or is it 16? If I was to use a 2 byte character set then would that cut the size of my allocated local storage space by half?

In my project i am using ajax and jquery. After going to a page via ajax without page reload i want to see the same page if the user refresh the browser. I used the cookie plugin inorder to solve. As it is not safe i am trying to do the same using session. I have dowloaded the jquery session plugin and initialized the session variable using the below satements.
var SESSION_URL = $.session("current_url",Url);
var SESSION_DATASTRING = $.session("dataString",dataString);
and i am getting the session value in the same jquery $(function) where it is initialised, through alert($.session("current_url");
But i am not getting this session value in an another jquery event like
window.load(function(){
});
How can i get the initialized session value in an another event.
I am trying to reference a session variable inside some JQuery code. Theseexamples below arewhat I am using currently just to try and see if I can get something to display and nothing shows up.[code]Just to make sure an alert works, I threw in a alert("hi"); which works fine. It is when I try to write out the session variable it fails.

View 5 Replies View RelatedI can successfully change the background image using the following:
jQuery(document).ready(function($) {
$("div#largeimage").randombg({

But, what I want to do is change this ONCE per user session. So instead of change this on every refresh / page load I want to load it once, store that setting in a cookie/session, and not do it again until the next session.
I have a little problem with saving a single checkbox state (check or uncheckd) for a session with jQuery.
I did find similar problems and solutions but i couldn't apply the help or solutions to my situation. So i give it a little try here..
Good to know is that I'm new to jQuery.
What i would like to achieve
I have one single checkbox that, when checked, will unhide some div's. When you uncheck the checkbox the div's will hide again. This is sort of an "Option". This works fine with the piece of jQuery code i have now.
The problem is that when a user checks the checkbox and then loads another page (/page2) the checkbox is unchecked again. I would like to store the checkbox state for a session. So users don't have to check the checkbox again, and again after browsing to the next page (if they wish to use this option).[code]...
I have a php page (target_market.php), with a form that has 34 checkboxes. I would like the be able to click the boxes and have JS post the 'checked' value to a php session varibale when a button is clicked. If the user navigates away from the page and returns, the pages needs to reload the checkbox session variables.
How do I post the 'checked' value as either YES or NO using JS to another page (target_session.php), so that i can add them to database at a later stage?, but also retrieve the session variables and update the check boxes should the user come back to the target_market.php page?
i have a requirement in which i want to use click event to set some value into a jsp session object.
now from what i have tested, this seems to be logically very wrong, but the fact is that i want this thing to work somehow as there are no alternative for me in this case.
here is the code which i am trying.
$(document).ready( function() {
var key = 'false';
// initial value
[Code].....
i know that this question might come into the category of absurd questions, but can anyone point out some logic for something similar, i have a jsp page and i want to set these values in the session based on the button click.
I have a question here, I have a mother page of 2 divs, one for the category list of foods on the left and the right div is a placeholder for the selected food of the category,
Then i have a modal box, which loads the list of foods associated to the category when clicked,
What i wanted to do is, when i select a food from the modal box and click submit, I wanted to populate the selected food into the right div of the mother page, so far the farthest i went is loading the list of food into the modal window,
its like a shopping cart, but instead of redirecting your users to another page, you display all their orders on the same page... can this be achieve, im using jquery+php sessions
Right im trying to incorporate a splash screen on recent project like the one here... [URL] But im trying to implement cookies with it so it only loads the splash screen once every browser session but i havent managed to figure this out yet
View 2 Replies View RelatedI'm creating chat with LONG POLLING. To keep main domain ajax requests (send message) untouched (unqueued), I had to put my long-polling script to subdomain.So I've got 2 "domains"
foo.cz
channel.foo.cz
I do not mind about any Same Origin Policy right now as I put
header("Access-Control-Allow-Origin: *");
at top of that script. I also do use
ini_set('session.cookie_domain', '.foo.cz');
in all scripts (sending, receiving, chatting room).
For debugging, i've got this in my channel.foo.cz/getNews.php:
print_r($_SESSION);
print_r($_COOKIE);
die();
My problem is:
I do load chatting room Ajax (jquery) requests channel.foo.cz/getNews.php getNews.php returns this:
array()array()
It look that cookies and session isn't setted up. But! If I look into my FF cookie browser, I do see that domain for these cookies set in chatRoom is .foo.cz If I try to copy ajax request uri and paste it into browser url, it returns me
