JavaScript - Need Help Creating A Cookie With A Different $value On Reload
Hi,
i'm not sure this is the right spot for my question ,but i will try. ( sorry if not ) I need to create a script, that sets cookie ,named "something" with a random $value - something(1-500) every time the user refreshes his browser. Something like this : Y.Node.get("#Button1").on("click", function(){ var newValue = "something" + Math.round(Math.random() * Math.PI * 500); Y.Cookie.set("$something", newValue); Y.log("Set cookie '$something' to '" + $something + "'"); But when i refresh the browser the cookie must be with a new Value. I will explain more clearly : I hit Button 1, Activate this script,that sets me the cookie named "something" with a $value for example , something55 I refresh my browser,the same cookie has $value for example something98 Thanks in advance, Regards, Anton P.S. i'm trying to make it work for a few days .so i will be very glad if someone could help me here . Similar TutorialsI am creating a cookie that increases a "value" or "integer" by 1 (ie Y+1) every time any page inside my webpage. Any webpage that i put the code into. right now I need it so that when you visit a page with the code it increases the variable or "cookie" (Y) by 1. when Y reaches a certain number, I.E 10, it resets Y to "0" and redirects you to a URL. Please explain where each value would go in any replies. Please make code as simple and as low in file size as possible. I don't need any sort of flexibility, just a simple redirect to a webpage which WILL NOT have the cookie code in it. EX: when opening the menu of an iPod game it asks you to rate the game, saying remind me later resets the value to "0" and saying rate now, resets to "0" but does not keep counting on the next page. Thanks to all in advance and i hope you completely understood my problem and question! [spoiler] Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

Hi everyone, I am using a jQuery cookie script to set the cookie of some elements on my website.

This is my dilemma and I am not sure if I am handling the right way, so please suggest a new way or provide a valid answer so that I may achieve my goal. Thanks in advance for your help in solving this matter. In short I have a single "A.html" page that uses AJAX to reload in "B.php" into a <DIV id='bDiv'> every second and "C.php" into another <DIV id='cDiv'> with no reloading. The code in B.php generates a random number between 1 and 100. If the number generated is less than 10, I want <DIV id='cDiv'> to refresh its content. I have tried a number of tricks, I could not find anything in jQuery so if there is please point me to the correct function calls. hello im working on my senior design project for my electrical engineering class. and part of the project is to upload an image via php (which ive written and it works great) but when the image is loaded into the same directory as the html file (which is supposed to display the image everytime a new image is uploaded) the image stays the same it doesnt show the new image. but i kno the new image has been uploaded because i can see it my web server. this is the code Code: <html>
<head>
<title>Human Cam</title>
<script type = "text/javascript">
function refresh() {
var refreshTime = 5*1000; //5000ms
var thisImage = "Lighthouse.jpg"; //the image location
var today = new Date(); //the current time
//add the time to the end of the image string
//to make a unique url:
document.images["pic"].src=thisImage+"?"+today;
//reload if the images are loaded:
if (document.images) {
window.onload=refresh;
}
//IF the time is up reload the image
t=setTimeout('refresh()', refreshTime);

I have a index page on which there are several iframes which point to pages from a tomcat server. Sometimes when the index page loads, most of the iframes display session expired error. When I refresh the page, all iframes load properly. I want to reload the page twice whenever I come to that page initially. I also want to reload that page twice when I come to it from another page. Any ideas are welcome. I have tried the following in the onload event ----------------- if(window.location.search.indexOf('reload')<0) window.location.replace(window.location.href+'?reload'); --------------- function loaded() { if (!navigator.fudge) { navigator.fudge = 0; } navigator.fuge++; if (navigator.fudge>1){navigator.fudge=0} else{location.reload()}; } ------------- if(readCookie('reloaded')!='Yes') { createCookie('reloaded','Yes',1); window.location.reload(); } else eraseCookie('reloaded'); function createCookie(name,value,days) { if (days) { var date = new Date(); date.setTime(date.getTime()+(days*24*60*60*1000)); var expires = "; expires="+date.toGMTString(); } else var expires = ""; document.cookie = name+"="+value+expires+"; path=/"; } function readCookie(name) { var nameEQ = name + "="; var ca = document.cookie.split(';'); for(var i=0;i < ca.length;i++) { var c = ca[i]; while (c.charAt(0)==' ') c = c.substring(1,c.length); if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length); } return null; } function eraseCookie(name) { createCookie(name,"",-1); } --------------------------- several meta tags to get the page each time from the server e.x. <META HTTP-EQUIV="Pragma" CONTENT="no-cache"> <META HTTP-EQUIV="Expires" CONTENT="-1"> I have cpa gateway on a site that when the customer completes a function of the gateway. The external js of the gateway sends a command to the website to reload the site. Is there any way I can have some sort of event listener to know if that command is sent or not? The problem I'm having is its causing a loop in my existing JS. So it keeps looping the page. I would like to be able to set a cookie when the command is sent and then just have the cpa gateway not load. Thanks all! I haven't been on here in awhile so I have been learning a lot on my own! But this one stumps me Eric. Hi, I am using javascript function for refreshing html page. I have used [window.location.reload(true);] method to reload page from server. This code works if i use it by using Link/button etc. For Example: <input type="button" value="Refresh" onclick="window.location.reload(true);" /> But i want to refresh page when page loads. For Example: <body onload = "window.location.reload(true);> But this time, page reloads in an infinite loop. i don't know why... I have also used following function (against body onLoad) to reload and then stop, but this also does'nt work. function doLoad(){ var timeoutId = setTimeout( window.location.reload(true), 1000 ); window.clearTimeout(timeoutID); } Is there a way to stop reloading page after one refresh ? Thanks... If multiple pages reference the same external JS sheet, does the sheet reload every time you go to a new page or does it stay in memory?
Hey guys, I have read the past posts and I see that there have been some other people who have had issues with resetting a form. Right now - on this mess in progress - I have a function that runs on body load: Code: function load ()
{
document.forms[0].reset();
}
I know it is running because originally it was an alert, but this is not clearing the form. I need to get all checkboxes and fields to clear. I have also tried: Code: function load ()
{
document.getElementById("regForm").reset();
}
No dice. Any idea what I am missing? The temp page is he http://www.temp1.hangnailproductions...ISTRATION2.php My script is he http://www.temp1.hangnailproductions...egistration.js Thanks guys, sorry if things are clunky and sloppy, I'm doing my best but still pretty bad. -AJ topic has been answered
Hi all, I'm new to javascript and html so this may be a silly question, and I'm sorry if I'm posting this in the wrong forum section. Anyway, I need some kind of javascript that will work in a framed page. Right now when I try to navigate to another framed page located elsewhere on my website it's pulling it up in that frame, so it's an ever expanding framed webpage. I need it to simply open the new page up in the whole browser, and not in the individual frame.. Any help is appreciate, (There may as well be an html solution but I couldn't find one)... Thanks. Hi... I am having a problem with the resize... I use the script below to adjust the size of the frame. It works nicely for me. The only problem is, the frame initially jumps to the bookmark, and then on the reload, jumps to the top of the page. Any ideas on how to keep the frame at the bookmark in the web page, instead of jumping back up to the top???? Thanks much in advance.... <script> <!-- function resize_iframe(){ if ( window.frames["MainWindow"].document.body.scrollHeight=0 ) { } else { document.getElementById("MainWindow").height=100 document.getElementById('MainWindow').height=window.frames["MainWindow"].document.body.scrollHeight + 20 } } // --> </script> <IFRAME src="main.htm" frameborder="0" scrolling="no" ID=MainWindow NAME=MainWindow HEIGHT=800 WIDTH=1012 onLoad=resize_iframe();></IFRAME> I have several links that when a user clicks on one of them, it calls a javascript function that injects html using the innerHTML function. Lets say I wish to go to a different link, i would like to remove the already existing code and replace it with code that is called by the new function when the user clicked on the new link. I have already done a variation of parent.removeChild(element); and it didnt work properly. I have also tried location.reload() function but it seems to be refreshing the window AFTER i inject the html code with innerHTML function. Any ideas why it is doing this? It should refresh the window first and then execute the next line of code. It has been quite a frustrating experience for me. Here is a generalization of my code below: 1) event from anchor 'About Me': onClick executes function menuParser('aboutme') 2) switch statement in menuParser() executes code to inject html using innerhtml() 3) user decides to navigate to another anchor 'Science': onClick executes function menuParser('science') 4) in function menuParser() a parameter is tested to see if there is any injected code already 5) condition passes true and location.reload(); is executed 6) then code is injected again using innerhtml() I can see the changes made in a split second, then the entire page is refreshed. Any ideas? Thank you! -Nick Hello everybody What i am doing is: I reload a page periodically and do so with Code: document.location.reload() The Reload is implemented using Code: window.setInterval This works fine, except there is the problem with the focus: If the page with the reload bevaviour is in the background and i have another page in another IE window in the foreground, when the reload is called, the page with the reload in it steals the focus and is now in the foreground. Is there any way to avoid this behaviour? I'm using IE 7. Any help is greatly appreciated. I am running a simple show hide div script as follows: Code: <script type="text/javascript">
<!--
function toggle_visibility(slideshow) {
var e = document.getElementById(slideshow);
if(e.style.display == 'block')
e.style.display = 'none';
else
e.style.display = 'block';
}
//-->
</script>
<a href="#" onclick="toggle_visibility('slideshow');">Show Gallery + </a>
<div id="slideshow" style="display:none">slideshow</div>
It works but the page reloads and returns the user to the top of the page not to the "shown" div. Any way to send them back to the shown div or stop the reload? Any help would be appreciated. Thanks Hello Everyone, I am having trouble with a script that displays the url of an iframe. On this page, I have a single iframe and want to display the url of the iframe in a div. It works upon initial loading, but the url does not change when a link within the iframe is clicked and a new iframe page loads within the frame. My users need the ability to determine and directly link/view the iframe url. Here is the script Code: <iframe id="mainFrame" name="mainFrame" class="inner-center" frameborder="0" scrolling="auto" width="100%" height="400"
src="whats_new.htm"></iframe>
<p>
<div class="footer"><script type="text/javascript" language="JavaScript">
<!--document.write('<input type="text" style="width:100%; " ');-->
document.write( document.getElementById('mainFrame').src);
</script>
</div>
I am a js novice and trying to figure out what to research and implement. Can you reload the content in the div? do I want to look at cross-frame scripting? Any help would be greatly appreciated. Best regards, Eiger Hey everyone, I currently have a grid of thumnails which when clicked will load an image at the top of the page without reloading the page using the following JS: Code: <a href="JavaScript:;" onClick="JavaScript:document.all.Main.src='images/image01.png';"><img src='images/image01thumb.png'></a> This works wonderfully, However, what I need to do now is to produce the same thing but instead of loading an image, load an html file into the page without reloading. Is there a way I could use a similarly simple solution? Thanks hi i would like to create gallery of 6 images that will show random images on page reload without repeating them. am not good in js so any help would be great. i found some code on web, just changed path for images and added lightbox code. it looks like this, but it shows same image few times. Code: <script language="JavaScript">

thanks Sorry if this is the wrong place for this question, but... I'm having an issue with the difference in behavior between the IE and FF back buttons. I'm using jQuery to create collapsable div regions which contain text boxes on a search form. After submit, if the use clicks the back button in FF, the region(s) the user had previously expanded, show as expanded. Also, there search term is still present. In IE, when clicking the back button, all regions are collapsed, in there original loaded state, but the search term is still saved. I put the following code at the top of the page: onload=function(){ alert('Onload!'); } When clicking the back button in FF, nothing happens. For IE, the alert pops up. This tells me that IE reloads the page (but somehow still saves some things, like the search text). My question is, is there a way to keep IE from reloading when the use clicks 'back'? I will be creating my own 'edit' back button for users to get around this, but I also would like to prevent this from confusing users and causing undesired results. Any help would be greatly appreciated. |
