Basically on the load of a page I am making an ajax call that returns a string with integers seperated by commas. I have verified that the returns from the ajax call are working correctly, but then I am trying to take that string, break it into an array, and use the values in that array to use setTimeout and call the function at those intervals.
//Create our array outside of a function so it's available
var wait_time = new Array();
//function that handles the ajax return
function process_wait_time_return(str)
{
wait_time = str.responseText.split(',');
update_current_show(0, wait_time);
}
//Function that changes the div html with new information
function update_current_show(array_index, wait_time)
{
$("currently_playing").innerHTML = array_index;
var next_index = array_index + 1;
setTimeout('update_current_show(next_index, wait_time)', 3);
}
This is on a test page, so for testing purposes I'm just updating the div with the current array index to verify it's cycling through the array, which it's not.
I 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.
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);
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:
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:
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.
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?
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.
function calc(value, rate) { setTimeout("calc(value, rate)", 1000); } In FireFox error console it says that "value" and "rate" are not defined. But they are?
<script language="javascript"> <!-- function reloadOpener(){ setTimeout(doItNow,2000); } function doItNow(){ window.opener.location.reload(); } //--> </script> And there's a button in the body that says:
onClick="reloadOpener();"
When I try it without the setTimeout function, the opener page reloads no problem. I just need it to wait a wee minute, but when the setTimeout is there, nothing happens. Ever.
For the sake of completeness I have tried it with:
Note that if you press the start button N times, the counter increments by 1, N times. So you must press the stop button N times to stop the incrementing entirely.
The question is what is the semantics here that is responsible for this stacking, for want of a better word.
It seems like it just runs the last setTimeout line and pops out all at once. I've even tried adding a=, b=, c=,. etc at the begining of each line to no avail.
