Making Window Objects Persistent / Serialized?
Sep 28, 2009
I am trying to set up a chat window in my website. Pretty much I have the main page, and a pop-out child page that contains the chat. I want users to be able to change pages on the main page, but the issue is that when they change the page, the reference to the child page (where the chat is) is lost, is there a way to make the window object persistent such as serializing it and putting it in a cookie? It looks like JSON is made for like functions, but can't really serialize a window object.

I want to post a form and reload the results $("#shoppingcart").load("/catalog/shoppingcart.php", $("#"+frmId).serializeArray());
This works fine, but I would like to add a key and value to the array. How do I do that?

I have a web app, written in Javascript, that communicates to a back-end
server via XMLHttpRequest.
The logic goes:
* Login
* Perform transaction
* (delay while the user does something)
* Perform transaction
* ...
* Logout
It would be really convenient if I could make the whole thing a single HTTP
connection. That way, I avoid needing IPC and session management at the
server end, and a single instance of a CGI script can represent the entire
session. When the socket gets closed, the CGI script terminates and
implicitly logs the user off. All very simple.
Can I use HTTP pipelining with XMLHttpRequest to do this? The docs seem to
say (it's quite hard to tell) that I have to call open() after each send(),
which will presumably create a new HTTP session. Can I 'persuade' the
browser to reuse an existing session?

Is it possible to store other attributes than id and value of an input to a serialized array?Example:
html field:
<input type="text" name="NOT1NO" id="NOT1NO" value="1" custom="test" />
Using serializeArray creates array like
[
{
name: NOT1NO
[code]....

I've been applying a javascript based, user switch button to a site from this article: [URL] On [URL] (right top menu option).So far, it is working but the user selection is not persistent from page to page. I think it may have something to do with the onload and unload
actions in the attached js file: [URL]
}
window.onload = function(e) {
var cookie = readCookie("style");
[code]....
I was wondering if these functions have to be in the header of every page instead of in a linked file, or if there is something else I'm missing...

I have two divs, one with the ID 'leftcol' and the other 'bodydiv'. I have found some code on DynamicDrive site to resize and hide the leftcol div but I want bodydiv to expand to fill the space. Both are absolute divs though, and leftcol is simply "left: 210px;" and "width:auto;". The dynamic drive script is persistent so if I hide the menu it is still hidden on the next page. I need to do something similar. Say for example that I call it toggle (elementId), I need to hide leftcol and set "left: 0px;" for bodydiv, but next time show leftcol (can use the existing animation function for that) and set left back to 210px for leftcol. As I say, it must persist on each machine.

I need a little script so a window that I open when I load my homepage, will only display for like 5 seconds and then close itself. I've played around with meta tags to no avail.

I'm trying to make an ajax post to some php and whenever the user clicks the submit button, it reloads the page and is adding the serialized data to the URL thus breaking the page and giving me an error that I do not have a person selected. I've tried adding "return false;" everywhere I can and it still doesn't work. Here's my code:
// EDIT CONTACT AJAX
$("editForm").submit(function() {
$.post("/ajax/edit-contact.php", $("editForm").serialize(),
function(data) {[code]...
// I've tried adding a "return false;" here and it doesn't work
}
// I've tried adding a "return false;" here and it doesn't work
);
// I've tried adding a "return false;" here and it doesn't work

I'm trying to code a website that's built around an iframe (as in, the nav bar links to content which appears in a central iframe). Now, in one of my pages I've got links that are supposed to open a small text block when they're clicked.
how to do this using either divs or the DHTML window widget [URL], but in both cases the tab appears inside the iframe, and it's pretty cramped. I want to position it relative to the parent window, not the iframe, but so far haven't been able to figure out how to do this.

Is there a way in Javascript or Jquery to return an array of all objects underneath a certain point, ie. the mouse position. Basically, I have a series of images which link to various web pages but I have a large semi transparent image positioned over the top of the other images. I want to find the href of the background image that the mouse pointer clicks over.

I have an application that uses the Google Maps API to display
customized maps via a generated XML file. The XML is generated via a
"Wizard" system to determine what the XML holds.
I am looking for a way to keep the XML file "persistent" across the
pages via Javascript. The way the Maps API works is that the Client
feeds the items to be mapped to google, which generates the maps.
Storing the XML file on the server would mean I would have to download
the (possibly large) XML file each time the next wizard page displayed.
If the XML file was persistent on the client side (stored as a string
or document object), the display time would be cut, and my bandwidth
limits from my webhost would not be in danger of being hit.
I'd rather not have to access the wizard system session variables if I
can avoid it. Any ideas/references to code?

I'm trying to use the following code to load xml files:
ImportXML = function (ts) {
this.file = ts;
if (document.implementation &&
document.implementation.createDocument) {
this.doc = document.implementation.createDocument("", "", null);
this.doc.obj = this;
this.doc.onload = this.callBack;
this.doc.load(this.file);
} else if (window.ActiveXObject) {
this.doc = new ActiveXObject("Microsoft.XMLDOM");
this.doc.onreadystatechange = this.ready;
this.doc.obj = this;
this.doc.load(this.file);
} else {
alert("Error");
}
}
ImportXML.prototype.ready = function () {
if (myDoc[counter].readyState == 4) this.obj.callBack();
}
ImportXML.prototype.callBack = function () {
alert('loaded');
}
var xmlDoc = new ImportXML("bar.xml");
The problem I'm having is with the second line that reads
this.doc.obj = this;
IE tells me that object doesn't support this property or method. How is
it possible to get a reference to the object (xmlDoc) in the prototypes
'ready' and 'callBack" with IE?

I want to try and make a menu using javascript and DHTML. I want the
menu to be horizontaly placed on top of the webpage. When I move the
cursor over it a popup menu comes up. Sort of like what you can find
on the first page of Micrsoft.com near the top. But I want the menu to
have a more transparent blue color. Is that possible? Also where would
I go to find out how to do this?

If you have a javascript interpreter running in an environment unknown
to you (as in what objects it exposes to the language) is it possible
to loop through all objects in some way?
This is a non-browser environment, specifically the scripting engine
for doing xslt extensions in msxml.

"When we combine FUNCTIONS with OBJECTS we get METHODS". Then he creates an empty ARRAY:
var a = [];
then he uses the "push() method" to add elements to the array.
a.push(1,2,3);
uh, methods are for *objects* right? Yet he is using them on an ARRAY.how an array can magically becomes an object that is manipulated by a "method"?I mean, the array is still an array, no? It never actually becomes an object, right? Yet we still use a *method* to manipulate it. See my conceptual quandry?

I have a client who wants a gallery of images to pop up on her enter page similar to this site, http://bit.ly/mUscmo . It won't be identical, but she likes the way the images all pop up and then just stay there.I know how to function JavaScript, but I don't know how to write it from scratch. Is there any where I could find a code that does something similar to this?
