Textarea Manipulation With Variables?
Oct 12, 2009
This is a personal problem (he he) - not for work or school. I have tried to avoid adding Javascript to the things I need to learn but now I find myself needing to use it. I have several textareas in a form. I found (on this forum) a short piece of code (function) that will clear a textarea. It works just fine as long as I hard code the textarea name. I would like to use this one function and pass to it the name or Id of the text area I want to clear.

I would like to display a series of smaller foreground images on top of a
larger background image and possibly even control the position of the
smaller images dynamically. Is this possible? If so what is the syntax for
placing the small images on top of the large one.

I am attempting to pass two user inputs into one variable (text, not array) to pass through my credit card company.
What I have done it two "onchange" scripts so that when the customer enters their information the script runs it does a search and replace on "name" for there name and "number" for their number. However!! If they change their name (or number) a second time the search and replace will fail as it will no longer find "name". Therefore I though some sort of RegX facilitated where I prefix their name with a hypen i.e. '-'.
Is it possible to use regX in this way in Javascript? Can anyone provide advise or a link?
Alternatively, am I making this a lot harder than it needs to be!? i.e. could I do an onSubmit instead to change it? I have tried this, however it didn't seem to work.

I've written several scripts that have "while" blocks which increment a
date by one day if the date does not match one of a group of dates.
However, sometimes it apparently steps out out the while loop even
though my condition isn't met. Will work for a few loops then steps out
often.
Are there javascript "date" issues? I have also noticed different
results between Firefox and Internet Explorer.

New to javascript and still getting my head around strings...
Consider the following line of code...
var path = location.pathname;
....after execution, the variable "path" contains something like
"file:///C:/Documents%20and%20Settings/user/Desktop/Test/fileread.htm"
How do I parse this down to "C:Documents and SettingsuserDesktopTest"
....or at least to "C:/Documents%20and%20Settings/user/Desktop/Test"
Is there a better function to retrieve the source folder containing the
current HTML document?
I need to know the path to the current folder to reference other files in
the same directory using a FileSystemObject.

we have a piece of code which does some XML manipulation and it broke in IE (at least 7) between jQuery 1.5 and 1.6.At this link is the chunk of code running on 1.5.2:[URL]and at this link is the same exact code on 1.6.1 and erroring in IE: [URL]On the second link, IE is reporting an error down in jQuery for invalid number of arguments to a method. The second alert never shows.

I want a script to receive a time in the 24 hour time format HH:mm (e.g. 18:30) and remove 15 minutes from it.The problem is that if the time inputted was 00:00, then how do I get to 23:45?
I'm sure it's easy if you're in the know.I can do this with PHP, but not with JS.I just need the function / basic line of code that does this. I can work out how to call it etc. myself.

I'm trying to write some javascript code that will swap two rows in a
table, in an attempt to provide users with an easy and visual way to
manually change the order of the listed items in a table.
The sample code works as it should in IE, and switches the two rows
nicely.
In Mozilla however it fails the first time, but for some odd reason it
works fine afterwards.
Mozilla doesn't seem to be removing the duplicated node the first time,
which makes it appear as if an extra node is inserted into the table
(which is actualy the case), but on subsequent attempts, it seems to be
removing the duplicated node perfectly... Code:

I am trying to use Jquery as an XML tool to transform xml data other than the DOM.
This works very well and i can change my xml data.
Now i want back my whole xml that i just transform and this is where there is a problem !
$(xml).find('#id').html('some text').parent.parent.parent ... is not a good way
I read something about the defaultContext but it seems risky / hazardous.
Needed fonction would be $(xml).find('#id').html('some text').getRoot().html(); or something like that.

I've two different frames and I want dynamically read the value's with a for loop in a different frame by object name. See my code example:
alert(top.frames['hiddenframe'].contexthiddenform.afkorting.value);
this works.
Now I want to make the field name (afkorting) dynamically
strName = (top.frames['hiddenframe'].document.contexthiddenform.elements[i].name);
alert(top.frames['hiddenframe'].document.contexthiddenform. + strName + .value);
This construction isn't working. The variable strName gets the name of the object (i.e. afkorting) but the alert doesn't work. Has somebody an idea what I'am doing wrong?

I built an IE-only function that modifies the DOM to create a custom container with rounded corners and some shading at the top. It only gets called when the browser is IE and its version is < 9. It takes the following block:
And turns it into this:
The UI looks identical to FF, which uses the CSS3 attributes to create the rounded box. HOWEVER, in IE8, I can no longer access the embedded <input> element (which does not change). I'm trying to get the value of the <input> tag with the ID of "username" by doing this:
When I disable my DOM manipulation code so that in IE, it remains an ugly, square box, I can get the value of the <input> element with no problem. Once I manipulate the DOM, IE always returns the empty string while FF and Opera work perfectly.

I need this iframe for a facebook tab, since they changed the width to 520px. The original page in the iframe is 700px wide, and I've changed a few CSS properties using the frameReady plugin. It's works just fine, but trouble starts, when i'm navigating the target site, the CSS properties I've changed goes back to the original settings.
This is my code:
<script>
$.frameReady( function() {
$("#gmap-auto1map-gmap0").css("width", "520px");
$(".views-view-grid").css("width", "520px");
[code]....
Try clicking any of the 'view on map' links, then you'll see where I'm getting at.
How could I work around this? Can I make it apply the script every time something new loads into the iframe?

What I have going on is an input box where they type in an account name. And the autocompleter works perfectly if they choose an item in the list.However, I want them to have the option of entering an account that is not in the list. And when they do this, the onblur event triggers the opening of the New Account box where they can fill out the new account information and submit the form back.Once again when a selection is made it works just fine, it's when the user creates a new account that it doesn't trigger the "getAccountInfo" function.

In the below, I would expect this to return the number of milliseconds since the epoch. Instead, it's generating a massive negative number. I presume I've gone wrong with the set[Blah] methods.
javascript Code:
var date_text = '2009-03-06 12:00:00';
var d_tried = new Date();
d_tried.setYear(parseInt(date_text.substr(0,3)));
d_tried.setMonth(parseInt(date_text.substr(5,6)));
d_tried.setDate(parseInt(date_text.substr(8,9)));

I serched bug-fix and I found "metadata.js" but still not working in my Internet Explorer 7.It's just too nice to manipulate XML with jQuery...As a matter of fact... a simple example of extracting some data:Script page:

"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
