Setting Dynamic Links Based On Content Slider Current Status?

Mar 16, 2009

I have a content slider called "Codaslider" (ver 1.1 I believe) setup, and using CSS I have an absolute positioned image hovering above the slider at all times. The effect is what I want, where I have a static image of my company's product hovering above the content slider, and the background images slide around showing various features and such.

I would like to make it where the customer can click anywhere within the bounds of the content slider (including on top of the static image), and be able to follow the link for the image in the content slider.

For example, if the background image shows "New Features" or something similar, I want the customer to be able to click anywhere and get to the "New Features" page.

So basically, is there a way to dynamically set the URL that the static overlaid image points to, based on what page the content slider is on?

Here is the javascript that setups up the content slider:

Code javascript:
<script type="text/javascript">
var theInt = null;
var $crosslink, $navthumb;

Getting Href Attribute Of <base> Tag?

Jul 20, 2005

I'm trying to get the href attribute from the base tag in the document
head. The following does not seem to work... any ideas what I'm doing
wrong?


if(!(document.getElementsByTagName) ||
!(basehrefs = document.getElementsByTagName('base')) ||
!(basehrefs.length) || !(basehrefs.length > 0) ||
!(basehrefs[0].getAttribute) ||
!(basehref = basehrefs[0].getAttribute('href')) )
basehref = ''

This is essentially a very cautious version of:

basehref = doument.getElementsByTagName('base')[0].getAttribute('href')

The big hairy if just provides checks to make sure everything can be
done and provide a contingency if it doesn't...

I want them to enter something like:

And not an individual page like:

http://www.example.com/index.html

Drop Down Multilevel Vs. Base Href

Jul 20, 2006

I need to make a drop-down menu for my multi-level website. I need all the links on this dropdown to work on every page, no matter on what level (subfolders, sub-subfolders etc.) it's called out.

i have a base href tag on every page set to my index page the links in my drop down menu look like this location='supplies/painting.htm'

where 'supplies' is the folder contained in the main root folder, so it should be working but it's not. Whenever i click on this link while i'm in the 'about_us' folder, it tries to bring out the page 'about_us/supplies/painting.htm'

Only thing left to add is that this script is included "as is" with dreamweaver, and thats why i have no idea how it works. I'd code it myself, but the client wants it that way Code:

Overriding Methods In Sub Or Base Classes

Jan 20, 2011

In class based languages you can override methods in subclasses like so:
class BaseClass{
methodA(){
print( name() );
}name(){
return "--base--class--";
}}
class SubClass extends BaseClass{
name(){
return "--sub--class--";
}}

So the following code prints "--sub--class--"
(new SubClass).methodA();
So even though methodA belonged to the BaseClass, it called the overridden version found in SubClass. Would the equivalent code in Javascript print "--sub--class--" or "--base--class--" ?

JQuery :: Passing Base 64 Encoded String Through Ajax?

Feb 1, 2011

I have an image that is encoded as a base 64 string, and I'm having trouble passing that a WCF service using $.ajax(). I initally tried using JSON to pass the argument to the web service, but I kept getting 400 Bad Request errors for anything of reasonable length (if I just pass a test string in, it makes it through, of course). I've tried calling encodeURIComponent on the string before stringifying it, but that hasn't helped. I've also tried various content types ("application/json; charset=utf-8", as well as whatever the default is) and that hasn't made a difference either. Unfortunately, the request is being made through a mobile phone, so debugging options are few. Is there an upper limit to the size of the argument that I'm passing in this? The strings can be a few hundred kb at the low end up to maybe 1 or 2 mb at the high end.

Here is a snippet of the code I am using:

$.ajax({
type: "POST",
url: "http://www.myserver.com/MyService.svc/MyFunction",
cache: false,

[Code]....

No matter what the string consists of, it errors would with a 400 Bad Request error. No further information.

Changing Image In Frame From Base HTML File

Nov 2, 2010

Got an assignment for a javascript class and I have been banging my head against the wall for a week now.[code]In the main page I have tried several different ways to access the "src" property of the image, none of which I am 100% sure is correct. I think the problem is in the main page, in that I am not accessing the image right, but I could be wrong. I have spent hours on google and digging through the book, but I am still coming up empty handed.

Manipulating Css Lass And At The Same Time Having A Base Html Statement In My Html File?

Jul 16, 2010

I came across a very odd browser behavior when trying to modify a css class using javascript and at the same time having a base html statement in my html file.Without the base html statement, all browsers work fine and I can change the css class definition using javascript easily.With a base html statement, only FireFox still works while Internet Explorer and Google Chrome dont work anymore. If there is a cross-domain issue, while one browser does work and the others dont? An example of what I'm talking about, with the base statement:

http://freebsdcluster.org/~casaschi/tmp/example-base.html
Without the base statement:
http://freebsdcluster.org/~casaschi/tmp/example-nobase.html

how to tweak the code in the case with the base html statement in order for the javascript to work with all browser (modifying the class definition) ?I want to be able to manipulare css classes with javascript when a base html statement is in my html code.This is essentially the code:

<!--
-->
<base href='http://www.google.com'>
<style id='myStyle' type='text/css'>[code]....

Retrieving Form Value

Jul 23, 2005

I have:

1 form on the page. (no name, no id value set.)
3 hidden form elements named: catalog, vwoidc, oid

!!! I can only include the javascript right after the body tag. The
form is found near the end of the loaded page.

<form action="actionURL" method=post>
<input type=hidden name=catalog value=store>
<input type=hidden name=vwoidc value=69a6e1deb02417250691>
<input type=hidden name=oid value=60323></form>

Everything I've tried needs to have the javascript executed after the
page has been fully loaded.

Retrieving Cookies

May 15, 2006

I have the code below that will retrieve a cookie that was placed by the server (ie: joes.com) that the document resides on. I want to be able to retrieve a cookie set by another server (ie: freds.com) but I want to retrieve it from a page served by joes.com. This code apparently using 'document.cookie' determines the server that the document resides on and looks for cookies from that server. Anybody know of code that will let you determine the server?

var name = "cookie";
function getCookie(name) {
var cname = name + "=";
var dc = document.cookie;

if (dc.length > 0) {
begin = dc.indexOf(cname);
if (begin != -1) {
begin += cname.length;
end = dc.indexOf(";", begin);
if (end == -1) end = dc.length;
return unescape(dc.substring(begin,
end));
}
}
return null;
}

Retrieving The ID Names From Within A Form

Jul 20, 2005

Is their a way of iterating thru each tag within a form and returning the
value given in the id property, by that I mean the below html would return
the values idBoxOne, idBoxTwo, idBoxThree from the FormXX form.

<form name="FormXX" method="post" action="default.htm">
<input id="idBoxOne" name="bxOne" type="text">
<input id="idBoxTwo" name="bxTwo" type="text">
<input id="idBoxThree" name="bxThree" type="text">
</form>

Up to this point I've only used JavaScript to change CSS properties,
innerHTML and outerHTML so I'm rather new to the game.

Working With XML And Retrieving Nodes

Nov 14, 2004

function Xml_feed(file)
{
this.load = function()
{
var txt, str, title;
var threads = xml.getElementsByTagName('thread');
var len = threads.length;
var box = document.getElementById('box-a');
while (len-->0) {
txt = document.createElement('button');
title = threads[len].getElementsByTagName('title');
str = threads[len].getElementsByTagName('author');
txt.setAttribute('label', title[0].childNodes[0].nodeValue + ' by ' + str[0].childNodes[0].nodeValue);
box.appendChild(txt);
}
};

var xml = document.implementation.createDocument("","",null);
xml.onload = this.load;
try {
xml.load(file);
} catch (e) {
alert('There was a problem loading the XML file');
}
}
var feed = new Xml_feed('blah.xml');


in the red:

Is that how I should be retrieving the value from a child node? (the getElementsByTagName)..

in the blue:

I tried doing this.xml but had problems with doing that, i.e,
this.xml = document.implementation.createDocument("","",null);
this.xml.onload = this.xml.load;
try {
this.xml.load(file);
} catch (e) {
alert('There was a problem loading the XML file');
}
I'll guess that text in the red is why..
btw, this was in an XUL app.. not sure how much that would matter though..

Retrieving Certain Text From A Webpage

Dec 27, 2010

For a personal project, I want to see if I can make a Greasemonkey userscript (or eventually a Firefox add-on) to list how far a certain ad on Craigslist is from where the user is (by the city listed beside the ad). My question is really just looking for ideas on how I can parse out the city's from the webpage text (with javascript or some other language?). Not even sure if this is possible.

The city's or ads aren't their own div elements or anything (nothing can ever be so simple) - but the city's listed are formatted by <font size="-1"></font>, and each ad is in it's own paragraph tag.. maybe I can use that somehow?
