I'm troubleshooting some issues with menus closing and when I alert the return value from something like:
timer = setTimeout("closeMenu(id)",500);
I get 2,3,4. It seems to increment. Does that just represent how many times the timeout code has been executed?
when, inside a function, one simply says:
if(...) {return;},
one means something like exit, or leave, right?
Got a timing issue with sending a URI string out to a server side script right before a client side form validation process returns true..The problem is that the return true gets called to quickly for the submission of the URI string to be completed.So my question is, might there be a way to mix a return and a setTimeout?
View 6 Replies View RelatedI'm trying to move pictures around on the screen, with a slight delay
between the first picture and second picture (following onmousemove).
When I add the setTimeout function I must be doing it wrong because
the function that calculates the new coordinates for the picture
returns 32 million and change instead of the coordinate. This causes
the picture to not be able to appear on the display, obviously.
Here's the calling code (snipped for readability) that works without
setTimeout:
I've noticed that setTimeout seems to return a simple integer as it's "id" which can be used to clear the timeout ahead of time. So, in order to have multiple setTimeouts called (which requires the previous one to be cleared before the next one is called), I simply did this:
clearTimeout(setTimeout(function() {
/* some code */
}, 1000) -1);
Note the "-1"... each time this code is called, it starts a new setTimeout and clears "instance-1" which is supposed to be the previous instance. The idea is that this block can be called hundreds of times, and when the calling finally stops, the inner code is executed 1 second later. This SEEMS to be working (yes, even in MSIE!). Question is, am I fooling myself? Is this wrong?
appears only in IE: l2 = obj.parentNode.getElementsByTagName("select")[0].value; --> object does not support this property or method var l2 = obj.parentNode.getElementsByTagName("select")[0].value;
View 4 Replies View RelatedI have the following function that's supposed to say "Please make a guess" 20 seconds after an initial confirmation is displayed. However, it's immediately displayed as soon as someone hits "Cancel". If I change it's time to 40000 (20 seconds after the initial function is called), it does do it 40 seconds total, so it kind of does what I want. So it seems that the second setTimeout is initiated from the time the script is called generally, but I'm looking for a way specifically to have the 20 seconds start only after the "cancel" button is hit.

All is on the title, sorry for my english, i'm french :) I have an html page with style
<style>
#mydiv {
margin-left:auto;
margin-right:auto;
width:250px;
}
</style>
with jquery, i try to get the margin-left ($('#mydiv').css('margin-left'), but the function return 0px, unable to retrieve the good value (auto) anyone has idea to retrieve the value "auto" when margin-left is "auto" ?
I want know what is the mean of these symbol:
||
{}
I'm wondering if its because I don't fully understand setTimeout(). I have a web page that calls a function on the Onload. This function calls two separate functions and then
uses setTimeout() to keep calling itself. Each function randomly generates
a number and then I update the image.src with that.
If I run setTimeout() on just one function by itself, it almost always displays a new pic...but when I put the setTimeout() in the startup function a get a lot of duplicates. I've been watching it for a long time and I don't think it's a coincidence. Any idea
as to why it seems like both functions don't run/update the pic all the time? If I uncomment the line, alert("hello"), it runs all the time? Code:
i'm working on a small idea and i would like to run this code:-
document.getElementById(id).style.height = origheight+"px";
after a set time period (about 20ms i guess ;) ), however, the following line creates errors:-
var t1 = setTimeout("document.getElementById('+id+').style.height = '+origheight+'px' ",0.5);
any ideas why?
<img src=http://xxx.com/yyy.jpg
onmouseover="settimeout("document.location='http://www.google.com'"),
2000">
I want to have a 2 seconds delay before it is directed to an URL when the
mouse is over the image.
However, it seems that setTimtOut does not like parameters in the function
part.
I have a HTML page with a form with 2 buttons like this
....
<input type="button" value="Add" onClick="ClickAdd();"/>
<input type="button" value="Reset" onClick="ClickReset();"/>
....
I also have this javascript code:
----------------------------------------
function ClickAdd() {
setTimeout(test.Add, 100);
//test.Add();
};
function ClickReset() {
setTimeout(test.Add, 100);
//test.Reset();
};
Test = function () {
this.total = 0;
};
Test.prototype.Add = function() {
this.total++;
alert(this);
};
Test.prototype.Reset = function(i) {
this.total = 0;
alert(this);
};
Test.prototype.toString = function() {
return (this.total);
};
test = new Test();
-------------------------------------------
the thing is:
in the ClickAdd function, if i call test.Add() directly, is works ok But if I call it using setTimeout, the /alert(this)/ shows [object Window]....
Does anyone know whether the ECMA, or an other standard document,
specifies a maximum for the value that can be pass to the setTimeOut()
function in Javascript?
The below pasted code is my attempt to get the text of a span to change
every second. However, it seems to just set the text of the span to be the last item
in the array. Code:
I am modifying the suckerfish dropdown code to use settimeout to have
a slight pause before the menus disappear to make it more user
friendly. I have hit a snag with the following statement:
li.
{
timerID=setTimeout('this.getElementsByTagName("UL")
[0].style.display = "none"', timecount);
}
If I put take the statement
this.getElementsByTagName("UL")[0].style.display = "none";
out of the settimeout function, it works. (w/o the pause, obviously).
With the settimeout function, I get "this.getElementByTagName is not a
function" error.
I have tried putting this.getElementsByTagName("UL")[0] is a variable
and then using that in the settimeout function, but then each li will
only open the very last menu in the list. (ie all the menu items open
the last sub menu) Code:
Can I have two setTimeouts running at the same time - with two
different intervals?
I want to start one timer and, before it times out, start another one
I've tried this and they seems to interfer with one another.
var SessionTimer;
function StartSessionTimer()
{
SessionTimer = setTimeout('RedirectToSessionTimedOutPage(),60000)
}
function RestartSessionTimer()
{
clearTimeout(SessionTimer);
StartSessionTimer();
}
function RedirectToSessionTimedOutPage()
{
window.location = '/SessionTimedOut.html'
}
When I load the page and call StartSessionTimer(), I know it works because the page redirects after ten minutes (the value of 60000). However, in certain situations I need to be able to call back to the server with AJAX and then have the timer reset - that's when I call the RestartSessionTimer() function. When I do this, for some reason the ten minute window does not get reset.
To troubleshoot, if I remove the second line in the RestartSessionTimer() function the redirect is getting blocked (as planned). However, when I put the second line back in, the page just redirects as originally called - the SessionTimeout value is never
reset properly.
The code above looks good to me, but for some reason the SessionTimeout var does not get reset in the RestartSessionTimer function; it retains its original value?
I have a pop-up menu; one of those where you scroll over the menu, and
a submenu pops up beneath it. Everything's running smoothly on every
browser I've tested with, except for one problem on every browser: the
"clearing" of the menu.
The menu itself is being called by:
onMouseOver="menu(1)" onMouseOut="clearIt()"
function menu(x) let's "x" refer to a predefined array, which
determines which menu to pop up. That menu is stored in a variable,
showMenu. If x==0, then it changes showMenu to a whitespace, thus
"clearing" the submenu altogether.
clearIt() is a simple function, pasted here:
function clearIt() { setTimeout("menu(Ɔ')", 7000) }
The idea is that the menu will disappear after 7 seconds. The problem
I'm having, though, is that the 7 seconds starts after the first
onMouseOut, and doesn't restart when the visitor mouses over the
second button. So, if I look at the first submenu for 6 seconds, then
when I go to the second button the menu only stays open for 1 second,
instead of starting the timer over.
Here we are again pondering why setTimeout will not work, or rather mucks things up. This will work. addOn(obj);
function addOn (obj)
{
var parentNode = obj.parentNode;
var span = parentNode.getElementsByTagName("span")[0];
span.style.display="block";
thkOn(obj);
[Code]...
function funt()
{
var link = document.getElementsByClassName("class")[0];

I have a window up whose Javascript implementation checks for a cookie with code something like this:
function lookieCookie()
{
alert(document.cookie);
setTimeout(lookieCookie, 10000);
}
The first call to lookieCookie is in the onload event handler. The cookie is actually set by a PHP routine that is in another script. The PHP script certainly appears to be setting the cookie. The alerts from lookieCookie are clearely happening at the appropriate time intervals (I can't get into the room with the actual code at the moment, so if I have messed up the syntax here, I know that it is not messed up in the real code), but the cookie being set from PHP does not show up.
Obviously the PHP might be doing the wrong thing. In tha case I have to get on the guy that writes the PHP script. Should the code I wrote work even if the cookie is set after the page has loaded, but between iterations of lookieCookie()? If yes, then I must get on the PHP coder and get his page fixed.
I have an image that when hovered, another image pops up (this popup image has a 'learn more' button on it), but when someone attempts to mouse over the button, the image restores to its original image. I was advised to use 'setTimeout' but do not know how to apply it with the following code...
I understand WHY it's going back to its original state (the mouse is hovering outside of the area coordinates), but how can I apply the setTimeout script to DELAY the image from going back to its original state?
Script is suppose to print out a string with a short delay between chars... like a typewriter... Why doesn't this work?
<script type="text/javascript">function hehe(bam) { document.write(bam)}function CharPrinter(st) { num = st.length; i = 0; while(i <= num) { bam = st.substr(i,1) setTimeout(hehe(bam),1000) i++; }}CharPrinter("lol");</script>
I'm trying to build the framework for an AJAX back/forward button fixer. Basically it uses the hash fix for them (using text after the # to add history objects). To this effect, the function to check for updates has to be run every second or so. No problem, I'll just use setInterval for that.
For whatever reason, though, setInterval gives me an error. Specifically that oldLocation (global variable) is undefined (in the checkURL function). So I try setTimeout. Same thing. When I just call the function explicitly once (adding checkURL(); to the end of the script) everything works wonderfuly; it's just setting it up on a timer that messes up. Frankly, I've no idea why it's doing this. (The bug just seems so odd) Maybe a more advanced JS coder can shed some light on it.. Code:
I know sometimes javascript and php can be used together. Anyone know how to add a javascript set timeout to this? So that this php include will re-execute after so much time? Or is there a php refresh command I can add to this code itself, not the page.
