I'm having some experiment with the new html5 features, I got the point where I need to store and retrieve data that I don't know it's key or value. It is appeared that there is no document about I want to do.How can I retrieve the first, the last and all record(s) ?
View 1 Repliesm working on a website that uses a lot of ajax. There is a function to store favorites using the Cookie pluginon the site that works like this:

I have some code that attempts to save a user's preference settings. It first tries to use "localStorage", and if that fails (only old versions of MSIE), then a cookie is used instead.For example, if I intentionally misspell "localStorage" by instead using "localStor" (simulating a browser that doesn't understand the object name), the code simply does not run.unfortunately, that doesn't work.
View 2 Replies View RelatedI am working on a web app for the iPad and I am storing all my content in cookies. I am wondering how easy it is to transfer it to Local Storage.
View 1 Replies View RelatedWhat Ive done is use local storage to set a value in my web app.
Then my next task was to write said value on my page (This took me hours but finally got it done).
My next task is using Setinterval(or what ever the correct way to solve my problem) to subtract a number (lets use "1" for this example) Every 5 seconds from the local storage value.So basically After I click the button. Value is set and displayed. After another button is click. Every 5 seconds the localstorage is subtraced by 1. I think the code im looking for is similar to this

How to store some strings at the client side for firefox, chrome & IE?I use the Prototype JavaScript Framework on Windows Vista Home.
View 1 Replies View RelatedHow to store some strings at the client side for firefox, chrome & IE?
This code works on firefox & chrome but does not work on IE - no alert window appears.
var key = "localorder";
localStorage.setItem(key, 'asc');
alert('localorder ' + localStorage.getItem(key));
This code does not work on firefox, chrome nor IE - no alert window appears.
var key = "order";
sessionStorage.setItem(key, 'asc');
alert('order ' + sessionStorage.getItem(key));
I use the Prototype JavaScript Framework on Windows Vista Home.
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?
It seems that this code makes webkit browsers and opera anchor back to where the fade happens everytime the fade action occurs.
CSS Code:
.slider {
margin: 0 auto;
overflow: hidden
}
.slide_content {
margin: 0 auto;
width: 800px;
height: 202px;
}
.slide_content img {
border-width: 1px;
border-style: solid;
border-color: #43474A;
} .....
Been trying to add an image before the closing of the anchor tag:
<body>
<a href="http://www.test.com/">http://www.test.com/</a>
</body>
If I use:
$("a").append("<img src='testimage.png' /");
No image will appear in WebKit (Chrome, Safari, etc). Firefox and IE works fine.
Is there any way one can retrieve the local IP Address of a computer? For example 192.168.0.1 as opposed to the internet connection IP address. Or is there a way to retrieve a unique identity of a computer using either PHP or javascript. Or any other sort of code?

I have two Javascript functions to set and retrieve a cookie:
function setCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
} else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
function getCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
I can set and retrieve the cookie in Internet Explorer 9. The problem is that with Chrome, I don't know if it is not setting the cookie or not retrieving it right but I always get a NULL instead of the cookie value.
I have written this program:
var scores=[];
function sortScores(scoreRecs){
for(i=0;i<scoreRecs.length;i++)
[code]...
to take an array of variables in calling the function (ie sortScores), place these variables into an empty array("scores"), apply the bubble sort to scores, and then alert scores in sorted form. When I use test values like I have above, where they are all just numbers, this program works perfectly and alerts the "scores" array, correctly sorted. However, what I would like to do is to call the function with an array of records, each containing two fields, and apply the same sort to the array of records, based on the value in the first field of each record.To illustrate, i'd like to be able to call the function thus:
sortScores([{score:0,index:0},{score:2, index:1},{score:1,index:2}]);
and for it to sort the records in descending order of the value of the "score" field. So the above call would alert:
[{score:2,index:1},{score:1,index:2},{score:0,index:0}]
however, i'm not sure how i'd reference the numeric part of the f1 of each record in the sort?
What solutions would you guys recommend for storing data on the client? Is there something better than cookies? I've heard about the flash data storage, but, in my opinion, using flash for something as basic as client-side data caching is like using a sledge hammer to kill a fly.
View 1 Replies View RelatedDoes anyone have a reputable reference about internal string storage in
JavaScript? (for some particular implementation I mean).
Say having 1,048,576 characters long string from the geometric
progression:
function generateLargeString() {
var s = 'a'
for (var i=1; i<21; ++i) {
s = s.concat(s);
}
return s;
}
- the internal size should be 2 mebibytes and not 1 (?) if strings are
indeed stored as Unicode 16-bit. From the other hand it would be
tempting for an engine developer do not spend extra bytes on ASCII
chars...
So does anyone know of any documented engine optimizations on the
matter? Would be expected on some engine to have the string from above
twice smaller than say
function generateLargeString() {
// 1200 ETHIOPIC SYLLABLE HA
var s = String.fromCharCode(0x1200);
for (var i=1; i<21; ++i) {
s = s.concat(s);
}
return s;
}
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.

[URL]
check this url and i need one clarification in this image it clearly display the size of the mail box i 3mb and you are used already 21% like that,
this same scenario only we are going to use in our application , we are developing a H.R based application in that if client bought space from us.
for example if the client bought 250 mb space from us means, we need to intimate like that image which i posted above, -- ur using space is 250 mb ur alredy used 200 mb like that.
for this how is it possible using java??? and for this any server side works are there or using front side application itself we can finish this task?
Suppose I've made my range so that it covers a word, using range.expand('word'). Typically to add the next word, I would write range.moveEnd('word', 1). But this seems not to work in Webkit. Perhaps it should be implemented differently?
View 4 Replies View RelatedI have some JS code that uses XMLHttpRequest to get an XML file then loops through to display each item from the file. This happens relatively quickly but there is about a second delay before the content shows up--I want to display a loading message while that is happening. Everything's working great in Firefox, but all the webkit browsers I've tried (Chrome + Safari), don't display the loading message in any fashion. It's not that the function to display the loading message isn't firing (because if I open it and then take out the code to close it, it does appear after all the XML processing is done).
I've even tried making opening the loading message a prerequisite (with setTimeout even, to make sure it's not just happening too fast), for running the XMLhttprequest, and it still don't show up. My hypothesis is that the browsers seem wait until all the processing is completed (ie: the XML file has been downloaded and converted to HTML) before doing anything. So both the open and close loading message functions are firing, but they're "let loose" at the same time so the net result is no loading message. I'm not exactly at liberty to disclose the code, so I'm hoping there is some known issue with this that someone is aware of, without having to show all my code.

This appears to be an issue with webkit and not jQuery specifically, but I've noticed this:
NewDomRadio = '<input type="radio" checked="checked"id="testme" name=" testme" />';
$('div').prepend(NewEnumDom);
will not work in Safari (I'm using 5.0 w/ Snow Leopard).
Chrome appears to have somewhat fixed this, although destroying and recreating the element a few times re-introduces the bug. The source will read "checked=checked" correctly, but the DOM inspector reports checked: false.
There seem to be two workarounds:
1] Removing the name attribute (!!!)
2] Placing the checked attribute at the end.
