hello,
i want to make a counter. It is something strange that i want to do.

Well, i want to check 2 variables and then if one variable is bigger/lower to increase/decrease a counter.

I had make one but the max number was only 1/-1



<SCRIPT>
<!--
R1=(will be from 0-1024);
R2=(will be from 0-1024);
var R11=0;
var R22=0;
var R3=0;

if (R1<100)
R11++;

if (R2<100)
R22++;

if (R11>R22)
R3++; //my problem is here. it can't take more than 1
if (R11<R22)
R3--; //same here

document.write(R11);
document.write(R22);
document.write(R3);

// -->
</SCRIPT>

Hi,

Firstly this is a javascript issue, not a java issue so your post should be in the scripts forum.

The reason you only ever get to 1 and -1 is that your code is only executed once, if you continued executing your code in a loop of some sort or keep refreshing the page and passing the current values each time you refresh as parameters, reinitialise your counter variables with the values passed and execute your code again - then you will get passed 1 and -1.

I don't know how you can do it every 50ms though. You could refresh your page every second, not sure how to get milliseconds.

<meta http-equiv="REFRESH" content="1">

this will refresh your page every second. Remember to pass your values to the page when you refresh.

Hope this helps

Hi,

Sorry I forgot you will need a server technology like JSP, ASP or PHP in order to pass and retrieve values between pages. I think you should rather ask in the scripts forum, they will be able to help you better than I have.

I'm not a java script coder. If I understand the problem right, then you need some simple counter that is updated periodically.

Take a look at this code. You should be able to get what you need from it.


<html>


<head>

<script type = "text/javascript">

tid = 0;
count = 0;

var to;

function time()
{
tid=window.setTimeout("time()",to);

count ++;
f.result.value = count;
}

function start(x)
{
f = x;
to = 60 * 60; // change this value to change the "refresh" rate

time();
}

function cleartids() {
window.clearTimeout(tid);
}
</script>



</head>


<body onload="start(document.forms[0])" onunload="cleartids()">
<center>


<form name = "counter">
<input type = "text" name = "result" size = 8>



</body>
</html>

This thread doesn't seem to be going anywhere. If you could try to reexplain your problem, and post your most-up-to-date code, I can help you.

The first thing, I will say you'll need to use setInterval (not setTimeout). However, both receive a fucntion as a first argument, not a string as shown in the previous example:

var i = setInterval(action,time in miiliseconds); /* same as setTimeout */

i want to put that if (R11>R22)
R3++; //my problem is here. it can't take more than 1
if (R11<R22)
R3--; //same here
somewhere to the code that you gave me...because that i want from javasctipt is to check 2 variables. In depent from the values i want to "play" with the R3!

to = 60 * 60; // change this value to change the "refresh" rate

the time is hour? 60*60=3600sec?

Dr. Script

well, as i said at the beginning, i have 2 variables. The values are from 0 to 1024.

R1=(will be from 0-1024);
R2=(will be from 0-1024);

i check them:


if (R1<100)
R11++;

if (R2<100)
R22++;

i put 2 more variables that i want to check them later....


...and i want to increase/decrase one counter.something like that


if (R11>R22)
R3++; //my problem is here. it can't take more than 1
if (R11<R22)
R3--; //same here


the time that i want to execute those commands are in msec. Also i want to view the value of R3 at the broswer.

well i made that

function time()
{
tid=window.setTimeout("time()",to);
if (R1<100)
R11++;

if (R2<100)
R22++;

if (R11>R22){
count ++;
f.result.value = count;}

if (R11<R22){
count --;
f.result.value = count;}
}

it works somehow...

when tha page load, it checks if (R1<100) . If it is true, then the count begin to increase without stop!
i want to increase only one time and then recheck the two condiotions.

is any way?

I'm having a little trouble following what you need.

Why don't you post what you have done already.

}

function start(x)
