This is what I have:

JQuery :: Evaluate Component Of AJAX Response After Injecting HTML Component In Page?

Nov 1, 2010

You have an AJAX request and the response is mixed HTML + JavaScript. The javascript is referring to elements in the HTML component. Currently the JavaScript gets evaluated first thing when success is triggered and the HTML is returned as a parameter. Obviously this is not going to work ( in this scenario anyway ). As a previous Mootools user I was used to Request.HTML's responseJavaScript parameter and evalScripts option. None of there options are available in the $.ajax implementation.

P.S. I know I could make the javascript a file and load it separately. I know I can make my response JSON and have the js and html in separate properties of the JSON object. I want neither.

HTA Window Glue Component

Jun 2, 2005

Fully commented...

<?XML version="1.0"?>
<?component error="true" debug="true"?>

'HTA Window Glue' script component (file name: HTAWnGlue.wsc)


a tacky attempt at persisting 'window settings', to restore
size/position at run time (within available screen space)


include a link element inside an HTA element, like so:

<link style="behavior:url(HTAWnGlue.wsc)">


(no need for '<!--' these '-->' outside of this file)


*.xml is saved to the 'Application Data' directory (by default), in
a folder entitled 'HTAWnGlueData' the xml files are named/retrieved,
according to each HTA's APPLICATIONNAME value

the HTA's WINDOWSTATE attribute must be kept to its default value of
"normal" for the adhesion behavior to stick, so to speak...


there are three 'resource' tags in this component:

sets the top-level directory, where the data folder
is created; this can be changed in the text of that
tag, for example:
<resource id="glueDir">C:Temp</resource>
currently that is: 0x1a
(- the shell special folder constant for 'ssfAPPDATA')

"minWidth" and "minHeight"
set minimum dimensions of a window...


white-space counts as data in the resource tags

the initial resize can be hidden from view, if a seperate script is
included immediately below the opening <!-- <head> --> tag of
the HTA, like so:

<script type="text/JScript">

- "normal" WINDOWSTATE is important in this context

all things considered, the component is probably best suited for
resizable HTA's without minimize and maximize buttons...


<implements type="Behavior" id="GlueCode" />

<resource id="glueDir">0x1a</resource>
<resource id="minWidth">100</resource>
<resource id="minHeight">100</resource>

<script language="JScript">

JQuery :: Picking The Order Of Images In A Component?

Jun 22, 2010

I have a problem. I have a div component where I'll drag multiple images. This part is working perfectly. But I am not able to read the order of these images played in the component. What happens, I can play any position in the image of the div component, however, like to read in order as they are, from left to right.

I believe it is possible, but the solution must be complicated. Some of his friends could help me in the routine javascript to read this?

Background Image Gone After Adding JS Component / Get That Back?

Nov 16, 2010

Am just starting a new site and this morning noticed my header background image (logo) was missing.

Started out with normal CSS/HTML navigation menu.

Then I added a Vista buttons navigation menu:

and the logo was gone. Not exactly sure at what point it disappeared yesterday as I didn't notice it missing until this morning. The navigation is about the only point of difference so I think this is the issue but have no idea why.

Building A Horizontal Slider/menu Component?

Sep 8, 2011

building an HTML/CSS component that would:

1) Feature a small set of icons that would be placed on the right-side of a div

2) If someone clicked on one of the icons, the component would slide out towards the right, featuring various UI elements (i.e. descriptive text and form elements). The component slides out to match the width of the content (not fixed width)

3) The slider slides back if the user clicks on the "X" in top right corner or moves their mouse/clicks outside the slider area.

4) A nice to have would be if the component is towards the right side of the screen, the component slides out left (so it does not go outside the screen area or show a horizontal slider on the bottom of the screen window).

A visual of what I am trying to accomplish can be found in the attached file.

Firebug Console.log Not Working?

Nov 28, 2009

I have firebug installed in my firefox browser, but I can't get console.log, console.debug or console.trace to work. My console window remains empty despite all my efforts. For example I have some code which throws up an alert box ( alert ('here is an alert') so I know 100% that it is being executed. If I now place the line
console.log("please log this to the console");next to it, nothing gets written to the console. I also have firephp installed and this is logging to the console for my php code absolutely fine

Using Firebug To See What's Being Executed On An Element?

Jul 27, 2011

how I could use firebug to step through massive amounts of javascript that were written by someone else. I'm trying to figure something out for work which has me stumped.

An old co-worker wrote some scripts based on prototype to show input fields on a form when certain options were selected on the previous input fields. I'm trying to duplicate his old code but for some reason it's just not working. I can see that the reason those input fields aren't showing up is because display:none is being added on to the element by the js on the second step after the breakpoint (break on attribute change in firebug). This happens on the working page as well but the working page has about 10 more steps afterwards that eventually remove that style.

Uncaught Exception: Exception... "Component Returned Failure Code: 0x80004003

Sep 23, 2009

I am needing some help with an error I'm getting from a project I'm working on. First off let me preface this all with the fact that I'm a total javascript noob. I'm really trying to understand what I'm doing wrong. So any help or advice is MORE than welcome. Here's what is happening. I found this code that will duplicate a row in a table and modifiy the name of a input in the row. Well for my purposes I have two different tables I need to work with. (each one idividually) So I changed the code a bit to make it accecpt a variable to use for the table name. (before it was static) and now I'm getting a error. Error: uncaught exception: [Exception... "Component returned failure code: 0x80004003 (NS_ERROR_INVALID_POINTER)" nsresult: "0x80004003 (NS_ERROR_INVALID_POINTER)" location: "JS frame :: :: addRow :: line 14" data: no] This is the old code that would work (only for one of the tables)
