Using JS Cookies To Change Elements To Display:none
Aug 16, 2004
I've been trying to hack together a certain javascript lately, but as a complete novice I don't quite know how to achieve what I want.
Basically, I have a few information-request forms on my site. Once someone has submitted the form, I'd like the confirmation page to set a cookie, using JavaScript. Once the cookie has been set, I'd want to be able to hide page elements that have a particular ID or CSS class. Obviously, I can hide these elements using display:none. But, that only needs to apply to these elements if the cookie exists. If there is no cookie, the elements obviously need to show.
I've done quite a bit of research about JavaScript and cookies, but unfortunately have not found anything that works "out of the box" or that I understand well enough to hack together. What terms or concepts should I be looking for to learn how to do this? Or better, is there a script already out there that will work? If I could only find a working example, I think I could understand much better.

I run a review site with multiple cities. For each city page, I want to display different banners. When someone comes to my site, they select the city they are from and a cookie is set. The cookie is called "transfer_page" and the values are "LA" "NY" "London" etc.
I have different banner campaigns for each city. So, once a visitor has selected their page (and the cookie has been set), I want them to only see the banners that apply to their city.
Here is the cody I'm using right now. I'm using smarty templates as well, if that helps at all. (so I'm using the {literal} tag as well)
Here is what I'm come up with so far:
{literal}
<script type="text/javascript">
function checkCookie()
{
[Code]....

I'm not to good at javascript. I know VB.net, but I have not learned javascript yet. I am working on a project to get a survey to pop up for new visitors on the index page of our site.
What I need to do: On load look for a cookie, if that cookie is not found run a script telling the site to pull up another page in lightview [URL] using its own "on load" command. If the cookie is there the site will not open this other page.
What I've done: I already found a way to do most of this, but I can only use a hyper link as a trigger for the site to load the other page in lightview.
Here is a link of what I have so far: [URL]

I 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.

I am trying to display some xml elements that are formatted like [code]...
I can see that this is because of the [0] in the getElementsByTagName - if I change it to 1 or 2 it shows the 2nd or 3rd set of directions. But I want it to show all of them.

check the code snippet below:
<div id="Mu00">
<div id="Mu001"></div>
<script type="text/javascript">
jQuery('#Mu001').load('http://www.myserver.com/page1.html');
[Code]....
NOTE jQuery load function is used to fetch the content for the <div> above.
Everything works (it displays the content that is fetched by jquery load function), but it also displays the literal HTML code "jQuery('#Mu001').load('http://www.myserver.com/page1.html');
" and "jQuery('#Mu002').load('http://www.myserver.com/page2.html');
"

I've got a <div> inside a <form> which I show/hide when a user clicks on a show/hide link. That div holds several form options which I DON'T want to submit with the form when the div is hidden.
At the moment, even when my div is hidden, the values within it are still being submitted with the form.
Is it possible to / how do I - hide the div so any values enclosed in it do NOT get submitted along with the form?

So never done this one before so I am having a bit of a time trying to figure this one out.
Say I have a list of LI element and only a few of them have a inline style of display block, the rest have a display of none.
How would I go about looping through and dertmining the number of elements that have a display of block?
for(var m = 0; m < li.style.display.length; i++)
{
alert(m);
};
The above is just crazy but where my mind melts..

At my job I constantly need to be up to the moment on the weather, and I want to create a display that will combine important elements from different weather services onto one screen that I can hang on the wall. What are need are basic <div>'s from several different sites. I know I could use iframes but I don't want to display entire sites, just the elements I need from them. Then I want to be able to have some DOM control over them (e.g. setting refresh time for each element).

I have a feature similar to 'folding', where the user can hide parts of the page if they dont want to use these features.. some of this is done automatically, if a user chooses one type of template on the page, the settings for that one are displayed (and the other settings invisibleised).
Originally I did this with php, reloading the page with a variable to switch the sections on or off. This was proving to be a pain re speed and also cos there were a lot of form elements that needed to be saved each time it was reloaded.
So I decided to do this with javascript, using the following function:
function toggleDisplay(divId) {
var div = document.getElementById(divId);
div.style.display = (div.style.display=="block" ? "none" : "block");}
using block and none to either display or hide.
Problem is, I have lots of form stuff in the areas that will be hidden, and these are getting sent through on submit even though they are in a div thats set to display:none. I was hoping display:none would actually result in these not being sent.
anybody know of a nice clean way of preventing these hidden elements not being sent? (there are lots of em so it would have to be applied to the whole div that contains em)

I tried to enumerate through a index array to assign different ids to newly retrieved JSON data, the li element is initially set to be hidden and the hidden data can be seen from console. But the browser is failing to show the data when I tried to use ('li#a').animate({opacity: "show"}, "slow"); I also tried to use .animate right after each <li> appendTo the body and failed to show as well. I am wondering how to fix this? Is there any better way of handling this with out creating an enumerating array?

I have a list for example
<ul id="applications">
<li id="id-1" class="util"></li>
<li id="id-1" class="app"></li>
<li id="id-1" class="util"></li>
<li id="id-1" class="app"></li>
</ul>
Then I want a select some of the list with some animate effect, first the all of the elements would disappear, then the elements that I wanted would display one by one the code:
$('#applications li').each(function (index) {
setTimeout(function (e) {
e.hide("slow");
}, index * 100, $(this));
});
$('#applications li[class="app"]').each(function (index) {
setTimeout(function (e) {
e.fadeIn("fast");
}, index * 100, $(this));
});
The final effect is that all the elements would disappear first but the element I wanted would not display? Then I think about the queue,before I use it I change a little about the code:
$('#applications li').each(function (index) {
setTimeout(function (e) {
e.hide("slow");
}, index * 100, $(this));
});
$('#applications li')
.each(function (index) {
setTimeout(function (e) {
e.fadeIn("fast");
}, index * 100, $(this));
});
The yellow part is the different from the former one, the effect is that all the elements would disappear first, then all the would display again without any problem!

I am creating a form to enable advertisers to create listings on an accommodation directory site.One of the form fields is a drop down with the following optionshotelguestHouseselfCateringinnholidayParkcampingThe top part of my form is the same for all these accommodation types. However I need to include a section specific to the accommodation type. This section will include groups of radio buttons and checkboxes allowing the advertiser to choose which facilities/amenities are available.For exampleA hotel may have 24 room service campsite may have a shop on siteI was planning to have a separate div for each of the accommodation specific sections and toggling the display based on the choice of the accommodation type from a drop down list.I have just had a horrible thought that it may be possible if javascript was not enabled that either none of the sections would be displayed or even worse all of them at once.

My problem here is quite simple: I have a wrapped set of elements, and I would like to change the value of each one of them. Take a look here:
init : function() {
$('[data-role="page"]').live('pagebeforecreate', function(e) {
var page = $(e.target);
Localization.localize(page.find('[i18n]'));
});

I have been trying unsuccesfully for three days to figure something out, and it has brought me here. I am a noob javascripter, so please bear with me. I have created a page with an input button that refers to a function:
<!DOCTYPE html>
<html lang="en">
<head>
[code]....
i would like to change certain style elements of the array each time the button is clicked. I have 5 color sets i would like use for the page, so i would like the button to trigger the color change in a loop, ie when the last color group is reached, the next click returns to the original color set and it continues again.The things i want to change are the background color of two div's and the top row of a table. My style sheet is seperate, and I will also do the same for the javascript once I can get it to work properly.

I have two img tags and a jquery script which changes the value of the src attribute of each one picked from an array of images and alternatively set the display to block and assign a decreasing z-index.
The problem is that when the hidden image pops up, it seems as if, at first, set the css display to block and then change the source of the file as, for a second, it hangs to the previous loaded picture. Well I thought it was easy to manage by setting a delay but instead seems not to do anything. And then with a setTimeout but it doesn't work as expected..

I have an Iframe and some links to different pages. I have the code set up so that it changes the "src" to display the new page. The reason I have it set this was is because I want to be able to manipulate the content in the Iframe. I want to be able to hidden a portion of the new page once it is rendered in the iframe. This is what i have so far. Basically I need my intoIframe function to execute only after the has fully executed. How I accomplish this
Code:
function completeView(){
var tds = document.getElementById("alinks");
var link = tds.getElementsByTagName("a");
for ( i=0; i<link.length - 1; i++){
if ( i > 0){
link[i].onclick = function(){
showDoc(this);
return false;
}}}}
addLoadEvent(completeView);
function showDoc(whichDoc){
if (!document.getElementById || !document.getElementsByTagName || !document.getElementById("viewer"))return false;
var source = whichDoc.getAttribute("href");
var placeholder = document.getElementById("viewer");
placeholder.setAttribute("src",source);
}
function intoIframeUP(){
if (window.frames[0] != null){ alert('Frame is here');}
var mine = window.frames[0].document.getElementsByTagName("body")[0].innerHTML;
var sharepoint = window.frames[0].document.body.innerHTML;
alert(sharepoint);
}

I am new to JavaScript and I am having a difficult time finding what I thought would be easy to find.I have 4 text strings that when a user runs his/her mouseOver, I'd like to display a corresponding picture in a display area. I thought that would be easy enough. However, it gets a bit complicated for me since I am also using CSS to position the display area. For some reason all I can find out there are examples using HTML tables for display image positioning. I don't want to use tables. I'm not sure if this will make a difference but my style sheet is external. Also, the text does not link/go to another page.
