JavaScript - Auto Refresh On Jquery Script
I currently have this on my companies website and it's having a bit of trouble sometimes where it will only work after a refresh. Is it possible to do a refresh of this div and script as soon as the site loads, instead of using the auto refresh. I tried using auto refresh and it works but whatever time interval I put for the auto refresh is the time that the script pops up, so it kind of just makes it worst.
Code: <script type="text/javascript">
$(document).ready(function() {
$("#twitter").getTwitter({
userName: "lubellrosen",
numTweets: 4,
loaderText: "Loading Events...",
slideIn: true,
slideDuration: 750,
showHeading: false,
headingText: "Latest Tweets",
showProfileLink: false,
showTimestamp: false
});
});
</script>

PHP Code: setTimeout('updateShoutbox()', 4000); I know very little about js, so any help is appreciated. I have some sample ajax code i have been toying around with. I have it updating & working properly, but you have to click a button first. How can I set it so that it automatically reads the contents of the text file on page load, and updates every 1000ms? I was trying Code: onload=setinterval(JavaScript:xmlhttpPost("status.php"),1000)
but had not luck Any suggestions? Code below. PHP Code: <? $myFile = "testFile.txt"; $fh = fopen($myFile, 'r'); $theData = fread($fh, 3); fclose($fh); echo $theData; ?> Code: <html>

I was also able to get a button that toggles the start/stop of the scrolling. What I need to happen is when the scrolling reaches the bottom of the screen, I need it to refresh. Is this possible? Thank you in advance!!! I've a web page when a user logs in, it will have a link that shows the "username" and a link for "logout". After the user logs out, the "username" and the "logout" links will change to "login" and "register" links, respectively. The page uses javascript to check a user cookie, if the user cookie exists, it will show the "username" link and the link for "logout". If no user cookie exists, "login" and "register" links will replace the "username" and "logout" links. Here's the problem: When a user who has log in, clicks the "logout" link, a perl script will delete the user cookie, and redirects back to the same page. The page does not show "login" and "register" links AUTOMATICALLY. Both links will appear ONLY after the user MANUALLY Refreshes the page. It appears that I need a system to refresh the page automacally ONLY one time. How can this be done? I'm using meta refresh to refresh my web page. I have a small compose email window that appears via ajax when the user clicks on a name. Is there a way I can disable the screen refresh in my ajax code while they are composing their message? I have a web page that loads and Auto scrolls to the end. I need to either auto scroll up, or when it reaches the bottom auto refreshes back to the top. I have had to define a length longer than the document or I get scroll bars and the Iframe won't scroll. Here is the code. [Code] <html> <head> <script type="text/javascript" language="JavaScript" ></script> <title>How to Scroll the Page With JavaScript</title> <meta name="description" content="How to scroll the page automatically using JavaScript." /> <meta name="keywords" content="javascript, page, scroll" /> <script type="text/javascript"> function pageScroll() { window.scrollBy(0,25); scrolldelay = setTimeout('pageScroll()',5000); // scrolls every 1000 milliseconds } </script> </head> <iframe src="file:///D:/PrivateDocs/WorkflowPage/Stinkyxml.htm" name="frame1" scrolling="auto" frameborder="no" style="float:left" height="4500" width="100%"> <body onLoad="pageScroll()"></body> </iframe> <body> <body onLoad="pageScroll()"></body> </body> </html> [icode] Guy help me for the solution... how to refresh the markers only every x... below are my full scripts....

do i need to apply setInterval on the marker? how to apply it on the marker so it refresh every X second... please help for the solution.... If you go to a Youtube video by Justin Bieber or Rebecca Black, comments are constantly being posted and it seems like the autorefresh for the comments kicks in every half second. I don't plan on having millions of users viewing my page, but still, wouldn't having every user make a [mysql] request to the server every half second really take a toll on the server (especially since I don't plan to ever have the resources that Youtube has)? Facebook also seems to have instantaneous auto-refreshes, be it in comment boxes or their chat interface. So what would be the best method to implement a near-instantaneous autorefresh system with minimal resource usage? A noob needs some help. I'm using a combination of Yahoo Pipes and rssdisplayer.js to display some snippets from several RSS feeds on a new site I'm building. The trouble I'm having is that (i) the feeds don't update when I refresh the page, I think because a cached version of the page is being loaded, and (ii) I'd like to have the div containing the feeds auto-refresh at a given time interval. I've got a Twitter javascript working that does both these things, but can't work out how to get the rssdisplayer.js working this way. The rssdisplayer code is: Code: google.load("feeds", "1") //Load Google Ajax Feed API (version 1)
function rssdisplayer(divid, url, feedlimit, showoptions){
this.showoptions=showoptions || "" //get string of options to show ("date" and/or "description")
var feedpointer=new google.feeds.Feed(url) //create new instance of Google Ajax Feed API
feedpointer.setNumEntries(feedlimit) //set number of items to display
document.write('<div id="'+divid+'">Loading feed...</div>')
this.feedcontainer=document.getElementById(divid)
var displayer=this
feedpointer.load(function(r){displayer.formatoutput(r)}) //call Feed.load() to retrieve and output RSS feed
}
rssdisplayer.prototype.formatdate=function(datestr){
var itemdate=new Date(datestr)
return "<span style='color:gray; font-size: 90%'>"+itemdate.toLocaleString()+"</span>"
}
rssdisplayer.prototype.formatoutput=function(result){
if (!result.error){ //if RSS feed successfully fetched
var thefeeds=result.feed.entries //get all feed entries as a JSON array
var rssoutput="<ul>"
for (var i=0; i<thefeeds.length; i++){ //loop through entries
var itemtitle="<a href=\"" + thefeeds[i].link + "\">" + thefeeds[i].title + "</a>"
var itemdate=/date/i.test(this.showoptions)? this.formatdate(thefeeds[i].publishedDate) : ""
var itemdescription=/description/i.test(this.showoptions)? "<br />"+thefeeds[i].content : ""
rssoutput+="<li>" + itemtitle + " " + itemdate + itemdescription + "</li>"
}
rssoutput+="</ul>"
this.feedcontainer.innerHTML=rssoutput
}
else //else, output error
alert("Error fetching feeds: "+result.error.message)
}
//USAGE SYNTAX: new rssdisplayer("divid", "rssurl", numberofitems, "displayoptions")
//new rssdisplayer("adiv", "http://www.cssdrive.com/index.php/news/rss_2.0/", 5, "date, description")
Hey helpful people. I'm looking for a better solution to refreshing a page of mine, which currently single page (no frames) using meta refresh. To convert it something where it (using frames) would either: a. keep trying to refresh untill a var is recieved from the content, or b. present the browser with a button to refresh and a message that loading failed. But honestly i am a noob at javascript, to an extend i dont have much idea where to start on such a project. but learned this is not possible with regular html that is widely supported anyways. i suspect the:.. window.xx.location='url' ..is useful in this regard, but other than that i am blank on where to start. Any help is appresiated. Thanks in advance Jilli Most of the Javascript I see has some sort of time limit on page reload and is not really what I am trying to accomplish: Code: <meta http-equiv="Refresh" content="10; URL=http://coffeeandtealtd.com/buynow.html" /> I am trying to make our buy page reload after clicking the Paypal "continue shopping" button in Paypal Website Standards. The pop up Paypal shopping cart window closes after clicking the button but our buy page doesn't reload. It doesn't reload in Safari although it seems to be fine in FF and IE. I am new to javascript coding and am not quite sure how to make the page reload in this specific instance only. Any sug's?? I'm attaching my php test file but this is a JS problem. When I scroll down in the web page and the meta refresh hits, in Windows Safari and IE6/7/8 browsers, the web page re-positions back to the top. In Opera and FF the page refreshes but it stays where it is. Can someone look at my test script and see why it is not working in IE and Win Safari? My goal is to have the web page not re-position to the top on the auto refresh. Thanks... I'm wondering if anyone out there has a jquery solution to using an iframe that automatically adjusts it's height of the child and also works cross domain. Any help would be greatly appreciated. I have found a jQuery slide show at http://tobia.github.com/CrossSlide/ which interests me because of its smooth, cross-browser fade transitions. I would like to add a feature which automatically resizes the images proportionally, to fit the browser window. This feature is demonstrated in the Supersized slide show at www.mauitradewinds.com, but I am not satisfied with the quality of fade transition with Supersized -- especially under Safari. I would appreciate any guidance as to how to implement auto-resizing with the Cross-slide plug-in. Additionally, it would help if Cross-slide launched the slide show without waiting for all images to load.
Is this possible? I am writing a script that will display an alert box that reads "your play was saved" after a user clicks the submit button on a form. The only problem is that after clicking save, the page refreshes. Here is the code I tried to use Code: function savedMessage(){
document.getElementById("CmdFinish").addEventListener("click",function(e) {
GM_setValue("Saved", 1); }, false);
if (GM_getValue("saved", 0) == 1) {
alert("Your play has been saved");
GM_setValue("saved", 0); // or GM_deleteValue("saved"); }
}
The button ID is "CmdFinish" and the value is "saved". Is there ANY way i can make the script run only on a page refresh? **Note** The script is for a specific page and not the whole site, so it wont run on every refresh on the site, only when it's needed on 1 page. I was given this bit of code: Code: <img src="current.jpg" name="refresh" width="306" height="408">
<script language="JavaScript" type="text/javascript">
<!--
image = "current.jpg" //name of the image
function Reload() {
tmp = new Date();
tmp = "?"+tmp.getTime()
document.images["refresh"].src = image+tmp
setTimeout("Reload()",1000)
}
Reload();
// -->
</script>
to refresh a webcam image. I want to know what it means--how often is it set to refresh? I don't know javascript so I can't tell. Is it set to refresh whenever the image is new? or what? I would like to move away from my meta-refresh page-in-an-iframe method of refreshing my webcam if I can. My cam uploads a new image every 5 seconds. I need code that would allow the new image to be seen. Will this code do it? I tried it and it doesn't seem to refresh that often. So what does it do, and can it be tweaked? Hi All Is is possible to 'Refresh' a script when the browser window is resized? I know how to execute a script using the (window).resize event but I effectively need to 'destroy' the initial instance and re-load it. This must be acheived without refreshing the browser If it helps I'm using the SmoothDivScroll plugin which has a known bug whereby widths aren't recalculated when the window is resized. The script stops working untill the browser is restored to it's initial width and unfortunately I don't have the expertise to fix that All help appreciated Cheers Craig |
