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:
View 2 RepliesI have a function that changes the innerHTML of a DIV element. I want to pass to that function as a parameter a reference to the DIV to be changed. In the example below it works the first time (executed with the body onLoad event). As the subsequent function declaraton is rewritten by the function itself, it can no longer reference the targeted DIV. I tried to pass a string teference and use eval(), but this time it fails the third time it is executed.
Code:

I have develop an ActiveX with Visual C++ 6
And I will call functions on this ActiveX from a javascript.
I know how to instantiate the activex object (with the balise <object>).
But how can I do to call a function of my ActiveX and pass to this function
some parameter by reference.
Here is what I have :
the function in the ActiveX :
void test(long *t, long FAR* nb)
{
t = 3 ;
}
And here is what I try to call this function in javascript:
var myT = 0;
my_control.test(myT); // here is the problem that
alert("T : " + myT);
But I receive the value 0
So how can I do to pass parameter by reference to a function of an ActiveX?
Is there anything to change in my function in the ActiveX?
This code does not working in Mozilla. Works fine in IE.

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.
i'm wondering how i can get a reference to the next td in a row? Do i need to assign all td's an id or something? i could do that failry easily because the table gets generated dynamically via a php function.. i just hink this would be nice that way when i go to delete something (with those infamous checkboxes) i would like the javascript prompt to display what it is that will be deleted..
View 7 Replies View RelatedI need to do a function in javascript to check or

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.

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?
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
to each webform because the data is different. so in the separate js
file from a common function I want to call
PopulateSpecificForm(DataRow) and put that method in each webform.
It doesnt work? any ideas?
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;
and:
var referenceToBodyNode = window.body;
both of which got me "body undefined".
So what is the right way to get a reference to the body?
I'm working on an asp.net 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?

I'm looping thru all the document form elements with the below loop. While looping I would like to know if this element is from the second table in the form. My issue is the table has no name. How can I know if I'm dealing with an element that is in the second table of the form?
Code:
var field = document.forms['ovrFrm'].elements;
for (i = 0; i < field.length; i++) {
//DO SOMETHING HERE

This works in firefox:
document.eval(formname).elements.length
it does not work in any other browser
I call the same elements tag in lots of places, I'd have to wrap a large chunk of code in eval to make it work in other browsers. Is there any other way to call a dynamic object name?
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...
$(function(){
$('.table_pay').dblclick(function(){
if($('div', this).is('.value')){
[code]...
What to do on the 13th line that the reference object which is on the 2nd line (the class named"table_pay") will be its reference call..

View 2 Replies View Relatedi have a custom button on the browser toolbar which points to a html application (HTA) which launches it when clicked.

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?
