Using Var.replace("foo") When No Break Spaces Are Present?
Apr 28, 2010
I have grabbed all the links in an array and tried bubble sorting them alphabetically. The first two things I noticed was the " " which I can eliminate but I use Firebug as my debugger and it reports whitespace as whitespace. I do use a lot of 's in the HTML so it may be these that cause the results to show "undefined". I tried removing "undefined" and got a null instead. I tried removing the null and got undefined.
As I am looking at the ".text" property and Firebug probably shows as whitespace , maybe I should look for and possibly use ".innerHTML" instead. All I need is to remove leading, trailing & multiple spaces.

The first example works as planned and has a valid .height/width value, but the second and third example using encoding/space doesn't (0 height/width). I was under the impression that replacing spaces with %20 was supported?
1:
javascript Code:
imageFile = new Image();
imageFile.src = "/somedir/somedir/image.png";
imageFile = new Image();imageFile.src = "/somedir/somedir/image.png";
[Code]....
I haven't been able to resolve this on my own and searching for answers on the internet has been going on for along time now. I'm simply pondered as to why that encoded format doesn't work and how to use a spaced filename.

I'm trying to create/find a script that will do the following: -load a css file regardless of any conditions. -do not load the css file if a certain text is present in a specified html div tag.
i know this is done with a if/else state like this:
if (condition)
{
code to be executed if condition is true
[Code].....
how to add the condition for the variable text and to specify the css file.
I want the javascript to ignore loading the css if a div tag like this: <div class="menu-opener"><a class="gwt-Anchor" href="javascript:">Text1<img src=..//img.jpg"></a> /div>contains the word Text1, or any other I specify. Else, if any other text inside the div, the css should load normally.

I'm setting up an application that involves blog posts with comments boxes appended to the div that contains the posts. The comments boxes are in iframes and load an html file on the same domain. There are multiple posts/boxes on each page. I need a javascript that will only run the append script when the posts are written and appear on the page. So in non js language, I'm looking for this:
if div id post#5 appears on the page, show the iframe that contains the comments box that goes with post number 5. else don't show it.

I have a frame in which there are 2 IFrames., both being loaded from
the same domain. One IFrame is loaded from http://test1.xyz.com and the
other IFrame is loaded from https://test1.xyz.com/test
I am getting an error while accessing data in the HTTP IFRAME from the
HTTPS IFRAME.
Is it possible at all to access the data in the other IFrame, when the
protocol is different?

For example, I have the following:

I have been studying php for a while now and i know that, i am now starting php oop and that going well but i have never done anything like this. Anway i am creating a booking system which at the end of the process asks who supplied your voucher which they then select a supplier.
The issue i have is my client wants it so if groupon is selected then an input text box should appear so that the user can input a security code from groupon.
So basically it is
<select name="supplier" id="supplier">
<option value="">please select supplier</option>
<option value="Groupon">Groupon</option>
<option value="KGB Deals">KGB Deals</option>
<option value="Other">Other</option>
</select>
So if value="Groupon" then <input type="text" name="security" id="security" /> should appear next to it.
page cant refresh as it will lose its data which would have taken the user about 10 minutes to fill out :(

Do these functions include the height of an element's horizontal scrollbar (if present)? It doesn't seem to be mentioned in the jQuery documentation.

There is a website based game I would like to build, but I am not sure that the main functionality would be possible to program. I have tried to do as much research as possible. I know that javascript can do drag and drop, but would it be possible for the user to specify which images (out of a catalogue of thousands) they would like to be present on screen/toplay with?
It would need to work like this: The user is presented with a catalgoue of images. They can refine this catalogue according to things like colour, type etc. The user chooses which images they would like to play with by adding them to their personal choices (e.g. with an 'add this item' button). In the next step the user is taken to a page showing all the items added to their personal list, which they can then drag and drop around the screen. The user can then save/share their 'creation'.

I have a single javascript file that contains all of my javascript functions. Each of the these functions are particular to different pages on my entire site. How can I create logic that will only allow those functions to work when certain elements or identifiers are present on a page?

I'm working on a webpage which is completely self-sufficient. This means if you copied the source you would be able to load it locally without any glitches from your computer. I want to embed a "Save As" feature into this document using only javascript or jquery. For various reasons I do not have access to a server-side language to perform this action. I've done some research but can't seem to find a definitive way to do this.
My goal:
User clicks "Save As HTML" button which triggers jquery to copy the source of the page and present it to the user as a mypage.html download. My fall back approach will be to open a new tab with just the desired html and instruct the user to manually "File -> Save As". However, this is very undesirable and I would like to find a solution to fulfill the goal above.

I am currently trying to use Javascript to dynamically resize a navigation div (that is present on every page) according to the size of the main content div.
I am currently using the following code;
Code:
This works the first time I go to the site and if I refresh a page. However, if I use my on site navigation to switch between pages the div simply uses the height variable defined within my CSS (this needs to be here for users with JS disabled)
Does anybody have any ideas on what the problem might be. It's as if the script is only executed the first time any page on the site is loaded, but then not again.

I have a line of code:
var cdate=dayarray[day]+", "+montharray[month]+" "+daym+" "+year+" "+hours+":"+minutes+":"+seconds+" "+dn+""
What I require is a bigger space here:
var cdate=dayarray[day]+", "+montharray[month]+" "+daym+" "+year+" "+" "+" "+hours+":"+minutes+":"+seconds+" "+dn+""
I tried +"xxx"+ (where the xs are three spaces) but that didn't work either.

I am trying to get two values from a web service response.
The web service was called using jquery $ajax:
$.ajax({
url : "http://localhost:3032/ufs/integration/copymoveTerm",
type : "POST",
dataType : "xml",
[Code]....
All I want to do is to get the values of UNDO_COUNT and MSG into separate variables.
Here is the jquery I am trying to use:
function undoSuccess(xmlData, status, xmlResponse)
{
$(xmlResponse).find('res:OUTPUT').each(function () {
var undoCount = $(this).attr('res:UNDO_COUNT).text();
var msg = $(this).attr('res:MSG).text();
});
}
I have tried it with and without the name space "res:". I have tried it with xmlData and with xmlResponse I have tried changing the web service so that UNDO_COUNT and MSG were elements in their own right or were attributes of OUTPUT all without success it just bypasses the initial find on OUTPUT.

the title says it: is it ok to pass strings with spaces trough url? i tried it and it seems to work, but it also seems to me that more correct way to do it is to use '+' instead of space since that's what php get method does. i'm using window.location to redirect to another page.

Does anyone here know how to append whitespace nodes in mozilla without them being 'compressed'? Sampled numerous possibilities including 'u0020' but multiple spaces invariably get crunched down to one (MSIE is cooperative).
