Pass Parameters to Java Script?

[Al Franz]

Anyone understand how to pass parameters to a JavaScript. If anyone finds
this easy to do maybe they could take a look at my short script on this page
and show me how it needs to be changed.

Thanks for any help.

The page doesn't work.

I assume that you are talking about passing parameters from Java to
JavaScript, since you post in comp.lang.java. javascript. If it is so,
then you should check

Actually what I want to do is pass parameters from my HTML code to the
JavaScript. Not sure why the web page does not work for you, are others
having problems? Maybe it had a hiccup?

Add additional parameters to the function call:
<A HREF="javascrip t:launch('photo/2003047.jpg', 500, 300)">

Then, in your function:
function launch(url, wdth, hght) {
remote =
open(url,'','re sizable=yes,scr ollbars=yes,too lbar=no,locatio n=no,directorie s
=no,status=no,m enubar=no,copyh istory=no,width =wdth,height=hg ht');
}

No difference between passing 1 (url) and 3 (url, height, width)-- pass more
if you like.

For various reasons (see the FAQ of comp.lang.javas cript), you should
never use the pseudo-protocol "javascript :".

The best way is to use the ONCLICK event handler, and to use the SRC
attribute to specify an action which will be executed only if JavaScript
is not enabled (if you return false in the ONCLICK event handler).

Example:

<A HREF="nojs.html "
ONCLICK="myMeth od();return false;">
Text</A>

nojs.html being a page handling the case where the user doesn't have
JavaScript.

Actually, the script you propose doesn't work. See correction under.

Then, in your function:

Should be:

function launch( url, wdth, hght )
{
remote = open( url, "WindowName ",
'resizable,scro llbars,width='
+ wdth + ',height=' + hght );
}

What I did is

1) Give a name to the window. A window should always have a unique name,
to avoid nasty side effects.

2) Remove all the parameters which are set to "no" in the open method.
Parameters are set to "no" per default. It's not wrong to mention them,
but it's not useful.

3) wdth and hght are parameters, thus the string should be constructed
using the concatenation operator '+'.

Laurent,

Thank you very much, it is looking better but have a few follow up
questions. I implemented what you said at, even though I kept 2 "no"
parameters in there in case I change those....

http://franz.org/java.htm

1. Can I put the WindowName as a parameter in the HTML, since currently I
have to close a popup before opening a new one since the old parameters will
stick. Should it be in quotes in my HTML, and setup the same as wdth and
hght ?

2. Any way to set a background color for the frame in the window that pops
up?

3. Finnaly the wdth and hght I used as a parameter is the actual photo width
+ 20 pixels and the actual photo height + 30 pixels. Would it be possible
to hard code the 20 and 30 in the script so I could put the actual photo
dimensions in the HTML code parameters.

Thanks again, any help with me finishing up these mods would be great.

Yes, I mentioned you may pass the function any reasonable number of
arguements. Window name would be an arguement. Use it as you would any
other-- string arguements are passed in quotes, but do not quote the dummy
variable.

2. Any way to set a background color for the frame in the window that pops
up?
Hmmm... Not sure on this one. I suspect not-- as you are not actually
opening a document, but rather only an image. if your 'url' was an HTML
document, you could set the background color as in any other document.
Perhaps someone else will know better, or perhaps changing the 'url'
variable to an actual page containing the image is the only way.

3. Finnaly the wdth and hght I used as a parameter is the actual photo width + 20 pixels and the actual photo height + 30 pixels. Would it be possible
to hard code the 20 and 30 in the script so I could put the actual photo
dimensions in the HTML code parameters.

Yes. In the opener function add +20 and +30 to the variables describing
height and width.

Thanks again, any help with me finishing up these mods would be great.

Also, my thanks to Laurent Bugnion for 'fleshing out' my answers-- and my
understanding.

Tried adding that 20 and 30 every which way I could, but doesn't seem to
work. What is wrong with this format???
<SCRIPT language=javasc ript>
function launch4( url, wdth, hght)
{
remote = open( url, "WindowName ",
'resizeable=no, scrollbars=no,w idth='
+ wdth+20 + ',height='+ hght+30 );
}
</SCRIPT>

Is anyone imagined to be able to find anything in this "FAQ"? At
www.faqs.org is a "meta-FAQ" that points to a supposed "FAQ" at
http://developer.irt.org/script/script.htm -- but go ahead and try to figure
out where any information is located there about the pseudo-protocol
"javascript :".

Anyway, I've never come across this admonition, and I don't know why not to
use "javascript :". Several years of experience with it has turned up no
direct evidence of a problem. Can you fill us in?
