How To Get A Reference To Next <td>?

Apr 7, 2005

i'm wondering how i can get a reference to the next td in a row?

Name Reference

Mar 15, 2006

This code does not working in Mozilla. Works fine in IE.
<input type=text value=100 name=textbox>
This perhaps, because of Microsoft policy to globalize all tag names. Is there any method for cross-browser fix without using getelementbyid? Is there any method to pass values from outside of <script>, inside? (something like "global" in php functions) Javascript must be kept inside <script> tag.

How To Reference By Id More Elements With The Same Id?

Jul 23, 2005

I need to do a function in javascript to check or
uncheck all checkboxes with the same id. I want this function to work
in every form and every page of my site, as I will use the same id

Js Reference To A PHP Variable?

Jul 25, 2009

i have this code:if (! $_POST["Name"] || ! $_POST["LName"] || ! $_POST["email"] || ! $_POST["phone"])
$Alert_Message = "Invalid Form";
}i got a js script from another forum here on this site that looks like this, and does work well:print <<<JSOUT
<script type="text/javascript">
confirm("Form is INVALID");


exit;i have 4 different messages that i want to choose from to be displayed in the js script, and I want to store the message that i want to use in a PHP variable along the way. the variable is: $Alert_Message . i am trying to do this with my confirm() function in js:confirm($Alert_Message);the code is not registering, so something is obviously wrong. can i reference PHP this way in a js script? if not, how would i go about doing this another way? can i change a js variable along the way in my PHP code instead, and then reference THAT variable when i get to my js script?

Open A Pdf By Entering Reference

Jul 23, 2005

We're in the process of re-writing the Intranet at work, and my javascript
knowledge could be written on the back of a post card. ;-)

Can any of you point me in the direction of some code that would enable a
form to open a specific pdf file? Details are below.

All of our purchase orders are saved back to pdf files. Each pdf has the
prefix "PO_" followed by the po reference, then the file extension ".pdf".
For example, our file would be called "PO_12345M.pdf".
Each set of files is archived into years (folders are called 2003, 2004,
2005 etc.) so it will probably need a drop down box to select year, unless
it can search through all the folders.

The visitor should only need to enter the PO reference, and the code puts
the "PO_" and the ".pdf" on the end of it, and hey presto Acrobat opens with
the PO, or you get an error dialog if the file cannot be found.

Get Reference To A Possible Popup Window

Jan 4, 2006

Since a few years I make use of an online service which provides me
statistics about visits to my web site. The only thing I have to do is
to include a few lines of Javascript in the most important page. The
company providing this service - Nedstat - has been acquired by a more
commercial party called Webstats4U and they have now decided to cause a
popup window to appear with a commercial message, every new day you
start up the page. Given the nature of the web page, this is
unacceptable. Does anybody know how to check whether a window has been
opened from a page and - if so - how to get a reference to that popup
window so that I can close it?

How To Reference Js Code In Two Locations

Jul 8, 2006

Example: I have an aspx page with several fields and a grid. When I
click on the grid i use js to poulate the form layout. I have maybe 15 different forms each with a different table. I have a lot of common js code that I put in a
separate file.

I have a function in that file that needs t obe specific

What Is The Corrent Way To Get A Reference To The Body?

Oct 14, 2006

I've been doing this to get a reference to the body node of a document,
but I'm sure there must be something simpler than this:

var arrayOfBodyElements = document.getElementsByTagName("body");
var referenceToBodyNode = arrayOfBodyElements[0];

I tried:

var referenceToBodyNode = document.body;


var referenceToBodyNode = window.body;

both of which got me "body undefined".

So what is the right way to get a reference to the body?

Onunload Without Body Tag Reference?

Jul 20, 2005

I'm working on an site and am trying to implement a popup help
window. I want the window to close when the user advances to the next page
in our application. The thing is, I'm doing this on a component basis and I
don't have access to the body tag from within my help component, so I can't
add the onunload tag. Is there some other way of achieving what I want? Can
I add an eventhandler to the body tag through javascript?

Reference Parameter Question

Jul 20, 2005

I am writing a validation function: what I want to do when an error is detected is to open a second window containing error messages. The form being validated is rather long, and there are several points in the code where I write the messages. So, I would like to have a separate function just to open the second window with an appropriate title (something like "the following errors were detected in your form"). something labout like this:

Passing Object By Reference?

My question is commented in the script:

function Love(){
var req = {
ring : 'gold',


console.log(details.ring); // why does this return gold and not silver if req is passed by reference and we already changed its value above and so it's pointing to the same memory position?

Reference And External File

Apr 24, 2007

I found this javascript for a scrolling box to place on my web page. The information which scrolls in the scrolling box is embedded in the web page. I want to have it reference an external file. How do I do this?

The script set a variable called mymessage='Your message goes here'.

If I created a text file which is in the same folder as the web page, how can I get the text to be pulled from that file? Say for instance my file is at http://pacs/myTextFile.txt.

Multiple Forms - How To Reference DIV

Mar 24, 2011

How do I reference a div in a form when there are multiple forms on a page? Each form will have a unique id. I'm trying to change the style.display of a div in a particular form. I can alter elements inside that div (whether they have id's or names), but I can't seem to reference the containing div. For example, I have a div with an id=customOrder. Inside the div I have 3 objects. I want to be able to change the display value for the div instead of having to change each objects' display. I'm currently passing (this.form) on a button click (which is what triggers the display of this div - well hopefully eventually). I've tried several things, but I guess I'm not getting the right combination.

The ultimate thing I'm trying to accomplish (and maybe this is part of my issue) is I have a series of 2 drop down menus I want to use for numerous items for purchase. I've included the drop down menus as "php includes", so when the page renders out, there will be multiple instances of the drop down menus (multiple instances of id's and names) - unless there is another way around this, I've got to work this way. I've got so far as to be able to distinguish which form's "add to cart" button was clicked and its corresponding drop down values. As of now, when I code a textarea to be hidden, it hides ALL textareas on the page (because I can't figure out how to reference a div on a formID by formID basis... If I need to supply a mock-up example, I can put one together...

Invalid Character In String Reference

Jul 23, 2005

Is there anything 'wrong' with setting the value of a drop down menu
using the following?

document.frmStep1.drpInvaddress.value = 'A1020761603!>>R2'

This string is a key in our database that I have no control over and I
want to set the value of the menu according to this value because it
is unique. I suspect that the '' or the '>' or the '!' is making
Javascript think that this is a different type of data than string.

Is there a way to 'force' Javascript to interpret this as string?

How To Build A Reference To A Global Variable

Jul 23, 2005

I declare multiple variables halfway down the page. The number between "mech" and "Num" is generated dynamically in the XSL. Later on I need to reference that variable in a function, but I need to build the variable name in script. How do I convert it from a string reference to a ref to the global variable?

function changePreference(pos,mt){
//mt does not reference mech2Num, I need it to.
changePreference(2,'my' + pos + 'Num');

var mech1Num=1|2|3|4|5|6;
var mech2Num=1|2|3|4|5|6;
var mech3Num=1|2|3|4|5|6;
