| JavaScript object destructor method ??? Eli 19:20:14 |
| | Hi,
Is there any way that I can define a destructor for an object in
JavaScript that will be called automatically when object is discarded?
<script type="text/javascript">
MyOBJ.prototype=new Object();
MyOBJ.prototype.constructor=MyOBJ;
function MyOBJ()
{
alert('Constructor!');
}
MyOBJ.prototype.destructor=function()
{
alert('Destructor!');
}
var my_obj=new MyOBJ(); //<-- will show 'Constructor!'
delete my_obj; //<-- will show 'Destructor!'
</script>
-thanks in advance, Eli

| javascript submit problem : form won't submit Joop 10:06:28 |
| | Hi all,
I'm kinda new to JavaScript, but hey... I'm trying anyway! 
So, here's my problem :
I've created a table in my document, presenting a list of items, one
can 'select' by clicking on it... (Kinda like a menu, you make your
choice from) But since this table can get very long, I've put
something of a 'search-form' on top, which enables the user to make a
selection of products from the list.
Now, the form uses a "post" method, and submits to itself, using the
form action. Some PHP script will make sure that the form is filled
out already, the next time it's presented.
The table, containing a list of products is presented, below the form.
When a user clicks on a product, the product should be "selected". At
first i just used a <a href="zoeken.php?prod_id=24"> link to do this,
but the problem is that my form won't remain in tact.
So now, the global idea is to submit the form after setting a hidden
form-field using JavaScript, using a onClick event.
Here's my code :
<-- the script -->
<head>
<script language="JavaScript">
<!--
var old_Color;
function select_this(id)
{
old_Color = document.getElementById(id).style.backgroundColor;
document.getElementById(id).style.backgroundColor = '#FFCCCC';
}
function deselect_this(id)
{
document.getElementById(id).style.backgroundColor = old_Color;
}
function submit_this(id)
{
document.forms['zoeken'].select_id.value = id;
document.forms['zoeken'].submit();
}
-->
</script>
</head>
<body>
<-- the form -->
<form name="zoeken" action="zoeken.php" method="post" style="margin:
5px;">
<-- a very long form with a lot of variable goes here -->
<input type="submit" value="Zoeken" class="formulierknop">
<input type="hidden" name="select_id" value="">
</form>
<-- the tablerows, in the table, all look like this -->
<tr id="1" onClick="submit_this(1);" onMouseOver="select_this(1);"
onMouseOut="deselect_this(1);" style="cursor: hand; background-color :
'transparent';">
</tr>
Cool huh?!? Everything seems to work, but the submit function. Did I
do something terribly wrong?!? I probably did... 
WHY WON'T MY FORM SUBMIT WHEN I CLICK ON A TABLE-ROW?!?!?!?!? :-S
Thnx in advance to everyone spending time on this!

| IE form.submit() proudces invalid syntax error Bradley Kite 20:38:54 |
| | Hi all.
I'm trying to diagnose/solve a problem with internet explorer, whereby
sometimes the form submits, and other times IE produces an 'invalid
syntax' error.
First, I have a form, and within the form is a button bar and a <div>
block which contains a table of parameters. The div block is used to
create a layer.
Now, when the table contains 15 or less rows in it, any button on the
button
bar which calls form.submit() works as it should, however, where the
table has 16 or more rows, the form.submit generates an "invalid
syntax" error. IE doesnt provide any more detail on this error.
Mozilla/Netscape works as expected regardless of the number of rows.
I am using IE 6.0.2600.0000 but have also tried on other versions of
IE 6
and get the same results.
The code is as follows:
function _runButton()
{
document.getElementById('count_groups_form').submit();
}
<!-- Extra HTML removed -->
<form action="UpdateCount" method="get" id="count_groups_form"
enctype="application/x-www-form-urlencoded">
<input type="hidden" name="edit" value="0">
<input type="hidden" name="new_order" value="0">
<input type="hidden" name="action" value="">
<input type="hidden" name="has_changed" value="0">
<!-- Button Bar -->
<table class="button_bar" width="100%">
<tr>
<!-- other buttons removed -->
<td align="right" width="23%">
<input type="button" class="button" name="_run_button"
value="Run Count" onClick="_runButton();">
</td>
</tr>
</table>
<div align="left" class="count_groups" id="count_groups">
<table width="100%" class="without_border">
<!-- actual rows removed -->
</table>
</div>
</form>
Any help will be much appreciated.

| document.form.submit() doesn't work for large form fields Alan_atwood 09:56:02 |
| | Hello all. I am having a problem with the submit() method that is
driving me nuts. I'm using document.form.submit() with large text
fields (approx. 2000 characters) and am getting a "Invalid Syntax"
error. If I do the same thing with a text field of under 1500
characters, it works fine.
Is there some size limit here that I don't know about? Haven't been
able to find anything so far on this particular problem.
Thanks,
Alan

| Compatibility Issue Sev 18:35:20 |
| | I think (a bit clueless I'm afraid) I'm using a form script in the
template of this site: www.flywessex.blogspot.com
What I would ideally like to do is get rid of the 'Go!' buttons from the
right-hand side drop-down menus, so that the user simply has to select
from the list and is taken straight to the selected page.
I tried a script but it only worked in IE, not Firefox. I've been told
that it just cannot be done AND be compatible with both browsers. I
refuse to give up just yet and thought I'd ask you guys before making my
mind up.
Any help greatly appreciated.
Cheers,
P.

| Can Java Script allow me to calculate a future date? Guest 09:20:53 |
| | Im a long time java developer and actually have never done anything
with java scripting. I'd like to write a short simple script for
calculating a date in the future based on today's date and a letter.
Can I use javascripting to create a webpage to allow a user to enter a
letter and then click a button to find a future calendar date? I'm just
not sure how much user interaction scripting allows. Does java
scripting allow buttons, textfields and the ability to put enough
smarts in to calculate a future date?

| JavaScript Error Calling Webservice Zeez 06:14:22 |
| | Hi all,
I have a webpage that calls a webservice found on a remote computer.
Below is the code of my webpage:
=====================================
<html>
<head>
<script language="JavaScript">
var iCallID;
function init()
{
service.useService("http://www.webservicex.net/length.asmx?WSDL","MyMath");
iCallID = service.MyMath.callService(onWSresult,
"ChangeLengthUnit", 12, "Feet", "Inches");
}
function onWSresult(result)
{
alert(result.value);
if((event.result.error)&&(iCallID==event.result.id))
{
var xfaultcode = event.result.errorDetail.code;
var xfaultstring = event.result.errorDetail.string;
var xfaultsoap = event.result.errorDetail.raw;
// Add code to output error information here
}
else
{
alert("The method returned the result : " + event.result.value);
}
}
</script>
</head>
<body onload="init()">
<div id="service" style="behavior:url(webservice.htc)">
</div>
</body>
</html>
=====================================
When the "alert(result.value)" is reached, I used to get "undefined" as
a result but now it seems that the webpage freezes and nothing happens.
I'm sure that the webservice I'm calling is functioning properly (if I
type its URL in a brower, it works fine) and I'm sure that the
'webservice.htc' is there in it's proper location.
Note: The above webpage is hosted on a Windows 2003 Server which has a
public IP (i don't know if this might be helpful)
Any ideas would be greatly appreciated!
Thanks

| Finding line numbers of HTML elements E271828 05:06:13 |
| | Hi,
I'm helping to work a developer tool that verifies a given HTML element
has a given attribute (e.g., that all LABEL elements have a FOR
attribute, all INPUT elements have an ID attribute, etc.). Pretty much
all of the functionality is working except a feature that shows in
which line of the HTML source a violation of the user-set rule occurs
(e.g., where a LABEL element doesn't have a FOR attribute). There
doesn't seem to be a straightforward way with Javascript to find out at
which line a piece of a page's HTML code is, so I've been reading
through the XBL/XPCOM source code of Mozilla Firefox's Javascript
Console for some insight. While I'm slowly making progress with that
method, I was wondering if I haven't overlooked some way to do what I
want with Javascript. Has anyone dealt with this kind of problem?
Thanks,
Eric

| complex-syntax question...;) Maya 03:22:54 |
| | I'm trying to implement a drag-n-drop script, found here..
http://cwdjr.net/test/newDrag.html
but it doesn't work quite the way I want it to (div to drag-n-drop moves
down the window when I first click on it..)
I'm having a hard time dealing with the code because I don't understand
some things about it..
first of all, in this script the function that does the drag-n-drop is
called thus:
return dragImg(this,event)
but function is declared thus:
function dragImg(div,evt,how) {
what is the 'how' for ?? it's not passed to function from function
call.. if I take it out from function declaration get error that 'how'
is undefined, but where IS it defined in this script (I mean what does
it evaluate to before code inside function starts running (I tested with
an alert in first line of function, it prints 'undefined', so I really
don't get this...)
also can someone pls explain syntax of these var declarations? (rather,
they're var initializations, right?)
how = how || "relative";
var mx = evt.pageX || evt.clientX + root.scrollLeft;
I've never seen vars initialized like this in JS (or any other language
for that matter) and can't look this up because don't even know what to
search for....
thank you very much...

FAQ Topic - How do I protect my javascript code?
-----------------------------------------------------------------------
In the main, you can't as your code is distributed in source
form and is easily readable. With JScript, there is the Script
Encoder (see MSDN), but this is nothing more than obfuscation.
Disabling the right mouse button also does nothing to protect
your script in a Web browser.
Your code is likely protected under copyright laws. See:

| drag-n-drop Maya 00:22:28 |
| | I need a drag-n-drop script.. I have found one here..
http://javascript.internet.com/page-details/drag-n-drop.html
each div containing an image has an id, and each image has a name, as in
<div id="h" style="position:absolute;left:100;top:350;">
<img src=http://javascript.internet.com/img/cards/hearts.gif name="h">
</div>
but I don't see where he references these id's and names in the JS code..
functions are declared with param 'e', but I don't see this param being
passed to the functions when they're called (called thus:
document.onmousedown = MD;.. etc..)
I need to apply this to a div (which contains a table), but if I put the
same id and name to my <div> as he has here for one of the images it
doesn't work..
what am I missing please.. thank you..

| Populate input fields on a web form Ero 21:44:29 |
| | Is it possible to input values into a web form from an external source
like a client-side javascript?
There is a web site that I'm viewing where I have to enter 5 values in
the form. 4 of the values don't change only one input field does. Is
it possible to create a javascript to run which would popluate the
non-changing values by executing the script or by pressing a button on
the script?
No experience at this so any examples would be helpful.
Thanks

| Cross Domain Scripting with Friendly Domains Jacob JKW 17:53:50 |
| | Having read the CLJ FAQ and having done extensive Googling, I do
understand that in in general cross-domain iframe scripting is not
permitted. One issue I have not seen directly addressed, however, is
scripting across different but still "friendly" domains.
Essentially I'd like to send a signal from the child to the parent in
any form at all. I would think that there might exist a way to set some
variable or object property that could both be read by the parent and
written to by the child (or vice versa).
Am I just totally wrong?
Thanks,
Jacob.
