#16325 — setimeout() problem

http://www.jmrw.com/Chess/Tableau_echecs/index.htm#diaporama

On this page the button "stop" doesn't work everytime..

<button id="but_stop" onClick="stop()"> stop </button>

function stop() {clearTimeout(play); play = false; }

It should stop this function:

function diaporamarandom() {
c++;
document.getElementById('quantite').value = c;
c=Math.floor(Math.random()*listechrono.length)
document.getElementById('vue').style.backgroundImage = 
'url(images/'+liste[c]+'.jpg)';
play = setTimeout('diaporamarandom()',tempo); }

I don't understand why.

thanks

Declare play globally.

=============

var play = true;

function stop() {
   // clearTimeout(play); // not needed now
   play = false; 
};

function diaporamarandom() {
   if (!play) return;

Thanks

My var play is defined globally line 663 I think

Line 674 I added :

------------------
function diaporamarandom() {
 if (!play) return;
-----------------

diaporamrandom() does'nt work anymore.

if  I put

-----------------
function diaporamarandom() {
play=true;
 if (!play) return;
-----------------

diaporamarandom() works, but stop() does'nt anymore.

Use:

var play =  true;

Ofcourse it "works", it just returns if play is false.

Put that as the global definition outside the function.

Are you just experimenting with random code, 
or are you programming while understanding the code you write down?

<button type="button" id="but_stop" etc etc

Otherwise the button will submit the page every time you click it.

adding type="button" in

changes nothing

Only if the code is inside a <form>,
and even then only on certain inferior browsers.

Strange question,
even ideomatically questionable, 
only valid true if you do not wish to be helped,
define 'can' as 'will'
and define 'help' as 'take over your job or quest'.

Sorry, I am a beginner in javascript.and my language is french, so it is a 
bit difficult for me.

I have been told to put var play=true; as a global variable. I think I have 
done it and the problem is not solved.

Thanks

Our language is Javascript. ;-)
This is not an English only NG, some of us are French natives [not me].

Getting help is not the same as having your problem solved.

Please make a minimalistic code where you show what the problem is,
and show it to us.

Try to understand what each statement does and why.
Perhaps add temporary breakpoints to undestand the changing of the value of 
"play". Or use the console provided in some browsers.

If you understand the your problem yourself, perhaps you can fix it, 
otherwise maybe someone here will point you to the error in the code or in 
the expectation.

Then post in French.  The educated here will generally it easier to
understand good plain French than to understand what is thought to by a
French person to be sufficiently like English.

If you want the others to be able to read it, then add an English
version; but put at the top "posted in both French and English".

Then you can cross-post your question to c.l.j & fr.c.l.j rather than
posting multiply.

It's also a good idea to say that you have read the FAQ of this
newsgroup (if true).

Probably not.

You post a problem without bothering to format your source code for
readability, to give enough context to understand it.  Your URL points
to a page that doesn't validate, with source code that's very
difficult to read, and seems to be a mix of custom code and very old
auto-generated code.

Only four and a half hours later, after three separate people have
offered what help they can, you respond with this plaintive moan.  No
probably no one can help you.

It's a shame, because the page looks interesting, and I'd like to
offer help.

There's nothing wrong with that.  Beginners are welcome here.  But you
need to be willing to learn and abide by the conventions of this
group.  Here's some starter information:

I think Evertjan's advice is what you really need.  Try to make a
smaller test case that demonstrates the problem but doesn't have as
much clutter as your main code.  If you don't find the issue yourself
in doing this, you will be much more likely to get people here willing
to help.

Best of luck,

I apologize.

Cleaning and formating my code I found the error (an unnecessary function 
which disturbed)

I understand now what you were explaining me about formating  source code 
for readability.

I understand too that I cannot expect others do the bad job and the kind of 
questions I can ask in this newsgroup

Thanks having severe with me. It helped me.

My only excuse is I am a beginner.

I'm very glad to hear it.  Do you understand how and why it
interfered?

> for readability.

I was discussing it for the purposes of posting here, but it's a
useful habit in general.  If you can understand the structure at a
glance, you can spend more of your time trying to understand the
logic.


> I understand too that I cannot expect others do the bad job and the kind of
> questions I can ask in this newsgroup

There are plenty of questions you are welcome to ask here.  The main
thing is that you need to be willing to do enough on your own to make
it interesting for us to spend time on it.  And please remember that
it is not a paid help group, but a group of volunteers who are here
for discussing interesting aspects of the language, including at times
helping beginners.


> Thanks having severe with me. It helped me.

You're welcome, I guess.  It's funny, because I imagine my reputation
here is not one of being particularly harsh.  We have plenty of harsh
voices.  But your "Nobody can help me?" really annoyed me for some
reason.  I'm not usually so harsh.  I'm glad it helped.


> My only excuse is I am a beginner.

It's a reasonable excuse.  We expect you continue being a beginner for
a while.  But please do take away some lessons in appropriate posting
to USENET.

Cheers,

  -- Scott

Most people wouldn't have bothered to post that.
You have the right attitude.
