animated expanding frame

I am trying to create an animated expanding frame and I think I'm close but it's definetly not right. I'm using the "setTimeout" function to call the frame expansion functions but, either my time setting is off or I'm just not doing it right. I certainly don't understand the concept behind sequential function calls. Could you help and explain?

frames page:
------------------------------------------------------------------------------------

<frameset rows="80,300,*" framespacing="0" frameborder="0" id="ro">
    <frame name="head" src="blank.html" marginwidth="0" marginheight="0" scrolling="no" frameborder="0" noresize>
    <frameset  cols="*,400,*" framespacing="0" frameborder="0" id="exp">
        <frame name="left" src="blank.html" marginwidth="0" marginheight="0" scrolling="no" frameborder="0" noresize>
        <frame name="content" src="for.html" marginwidth="0" marginheight="0" scrolling="no" frameborder="0" noresize>
        <frame name="right" src="blank.html" marginwidth="0" marginheight="0" scrolling="no" frameborder="0" noresize>
    </frameset>
    <frame name="bot" src="blank.html" marginwidth="0" marginheight="0" scrolling="no" frameborder="0" noresize>
</frameset>



javascript:
------------------------------------------------------------------------------------

<script language="JavaScript">

function exp0(){
// the first one is if you want to remove the side frame...
parent.document.all("ro").all("exp").cols="*,450,*";
}
function exp1(){
// the first one is if you want to remove the side frame...
parent.document.all("ro").all("exp").cols="*,500,*";
}
function exp2(){
// the first one is if you want to remove the side frame...
parent.document.all("ro").all("exp").cols="*,550,*";
}
function exp3(){
// the first one is if you want to remove the side frame...
parent.document.all("ro").all("exp").cols="*,600,*";
}

var a = window.setTimeout('exp0()', 100000);
var b = window.setTimeout('window.clearTimeout(a)', 0);
var c = window.setTimeout('exp1()', 100000);
var d = window.setTimeout('window.clearTimeout(c)', 0);
var e = window.setTimeout('exp2()', 100000);
var f = window.setTimeout('window.clearTimeout(e)', 0);
var g = window.setTimeout('exp3()', 100000);
</script>

thanks

I'm not sure to understand the effect, but if you want to implement a sequence of function calls (exp0 then after 10000ms exp1, then after 10000ms exp2,... and so on), the script should be like this:

<script language="JavaScript">

function exp0(){
parent.document.all("ro").all("exp").cols="*,450,*";   // CHANGE PARAMETERS
window.setTimeout('exp1()', 100000);                     // START TIMER FOR EXP1 CALL
}

function exp1(){
parent.document.all("ro").all("exp").cols="*,500,*";  // CHANGE PARAMETERS
window.setTimeout('exp2()', 100000);                     // START TIMER FOR EXP2 CALL
}

function exp2(){
parent.document.all("ro").all("exp").cols="*,550,*";   // CHANGE PARAMETERS
window.setTimeout('exp3()', 100000);                     // START TIMER FOR EXP3 CALL
}

function exp3(){
parent.document.all("ro").all("exp").cols="*,600,*";
}

window.setTimeout('exp0()', 100000);

</script>

SETTIMEOUT is a sort of delayed execution of the given function, with the delay set by the user.

It worked! I reduced the time from "100000" to "1" and the frame expanded with a real animated look. It looks really cool. Thanks!

Now the thing I did wrong was that I had to many "timeouts"?

Since SETTIMEOUT is a sort of delayed execution of the given function, with the delay set by the user, you have to start timer for function EXP1 just __AFTER__ the timeout for EXP0 has expired.

This is the correct sequence:

1) start timeout for EXP0
2) after X ms EXP0 is executed
3) start timeout for EXP1
4) after X ms EXP1 is executed
5) start timeout for EXP2
...

If you write:

var a = window.setTimeout('exp0()', 100000);
var c = window.setTimeout('exp1()', 100000);
var e = window.setTimeout('exp2()', 100000);
var g = window.setTimeout('exp3()', 100000);

All timers start (and expire) togeteher.

And adding:

var b = window.setTimeout('window.clearTimeout(a)', 0);
var d = window.setTimeout('window.clearTimeout(c)', 0);
var f = window.setTimeout('window.clearTimeout(e)', 0);

Timers are canceled just after the start.

One more question. The script doesn't work in netscape. I never even thought to try it till my page was setup. :| is there a way to make it work?  Thanks for the explanation...

The problem is the DOM, try this:

Netscape 7.x and MSIE
---------------------------

<script language="JavaScript">

function exp0(){
parent.document.getElementById("exp").cols="*,450,*";   // CHANGE PARAMETERS
window.setTimeout('exp1()', 100000);                     // START TIMER FOR EXP1 CALL
}

function exp1(){
parent.document.getElementById("exp").cols="*,500,*";  // CHANGE PARAMETERS
window.setTimeout('exp2()', 100000);                     // START TIMER FOR EXP2 CALL
}

function exp2(){
parent.document.getElementById("exp").cols="*,550,*";   // CHANGE PARAMETERS
window.setTimeout('exp3()', 100000);                     // START TIMER FOR EXP3 CALL
}

function exp3(){
parent.document.getElementById("exp").cols="*,600,*";
}

window.setTimeout('exp0()', 100000);

</script>
