My firefox plugin called yslow that gives advice on speeding up loading times says: JavaScript scripts block parallel downloads; that is, when a script is downloading, the browser will not start any other downloads. the page load faster, move scripts to the bottom of the page if they are deferrable.
I always thought that js should be in the header. What do you think?
I have built a site that loads new content from a database when the user hits the end of the page. This works fine in all desktop browsers and on the iPad, but is not working on the iPhone. Have tried an iPhone 3g and 4.
Here is the code:
$(window).scroll(function(){
if($(window).scrollTop() == $(document).height() - $(window).height()){
$.ajax({
type: 'POST',
url: 'nextSet.php',
data: "?dummy=" + new Date().getTime(),
dataType: 'html',
cache: false,
beforeSend: function() {
$('#scrollLoading').show();
$('#scrollLoading').html('<p><img src="/images/ajax-loader.gif" alt="loading..." /></p>');
},
success: function(response){
$('#scrollLoading').hide();
$('#resultsPageSearch p').css('margin','0');
$('#sortDrop').show();
$('select.sortddl').selectmenu('destroy');
$('select.sortddl').selectmenu({style:'dropdown'});
$('#resultsSection').append(innerShiv(response));
},
error: function (request, status, error) {
alert(request.statusText);
}});}});
I hired a programmer to develop a drag and drop system for my blog. The user should be able to browse one of my blog entries and click, drag and drop an image from my entry to a fixed bottom bar on that page.The problem we are facing is that when dragging an image, it wont place it on the bottom bar until the whole page is scrolled down to the bottom of the page. This is a problem because some of the pages can be very lengthy
View 2 Replies View RelatedI'm building a simple portfolio gallery and am having trouble determining why the content is loading at the bottom of the page and then "jumping" into place once all images are loaded. This occurs in all browsers I tested on both the Mac and PC which were Mac - Firefox 3.0.5, Safari 3.2.1, Opera 9.6.3. PC-IE 6 and 7, Firefox 3.0.5, and Opera 9.27.

View 4 Replies View RelatedI have 6 headers that are animated gifs. They transition, 3 of them left to right, the other 3 right to left.I would like to have them to change to next header in sequence no matter which page on my site they click.I'm not sure this can be done, but think javascript is my best bet. Can anyone point me in the right direction?
View 4 Replies View RelatedI have a site that is very jQuery and image heavy. The main sections of the site link to sections that are built with several Tabs, and as it loads, you briefly see all the content load and then it is hidden by the Tabs code.
The plan is to have a full window DIV that sits above all the content with a loading icon that plays until the entire page loads, and then it fades down.
After some hair pulling and research I have code in place that does exactly as I ask, however it does not seem to work in IE6+7. It works in all other browsers.
The current code is:
CSS for the loading DIV is:
A working link is [url]
I have a lot of javascript functions that request information from an iframe hidden on the page. I see other sites do this, but their browser does not do the loading action (like the processing circle in Firefox). When I do it on my site, each browser shows the loading icon, as if a page was loading. Is it possible to not have this?

That is a sample link. Go down right side of page where you see three buttons: Trailers Featurettes Clips.Those return iframe information to work.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
Is it just extraneous code possibly? It seems to be ok (from right to left) in Firefox 3 but using IE and Opera, it scrolls from btm to top and I cannot figure out why.
I am using my script to update my table with the click number and then redirect to the stored href link code...
The only problem I have with this is that my web page gets replaced.
What I really want to do is open a new window and have the new web page in that. I can put a notice to say it will open a new window, its just that it will really annoy people if my page closes on them when they are half way through a tutorial !
What do I need to do to open the link in a new window ?
is there a way to rid of the page header (usually it's the page title and url) and the page footer (usually it's the page number and date) without having user to change from the web browser's the page setup ?
Can this be done using javascript or just html meta tags?
Also we control the contents of what is printed from a web page without having to redirect the page? Example, I have three paragraphs on a web page and I don't want the middle paragraph to be printed.
It's about my previous post I'm using a Java Script Calendar on external page(JavaScript). My problem is when you click on the page where the calendar is displayed it Closes down and it's visible after refreshing the page.
View 1 Replies View Relatedi'm new to JS and am trying to use an image several times on the same page, having each image show rollover behavior. The rollover code works for the first image on the page, but when I hover over subsequent images it only changes the rollover state of the first image on the page, not the image I'm hovering over. I'm using the following functions to change rollover state:
gallery_on = new Image ( );
gallery_off = new Image ( );
gallery_on.src = "gallery_on.png";
gallery_off.src = "gallery_off.png";

I�ve added a randomized header script to my page :
[URL]
The code is working correctly but due to the page load time - there is a delay in the new header image appearing when switching pages.
Here is the Javascript:
// JavaScript Document
var chosenImage=new Array();
chosenImage[0]="header_01.jpg";
chosenImage[1]="header_02.jpg";
[code]....
The function is called from the html page using the following:
<body onload="randomImage()";>
Is there anyway to avoid this delay or will i be forced to grin and bear it due to the weight of the pages i�m loading in.
I placed an anchor at the end of my long page inside a top <iframe>.
my entry field is in another iframe at the bottom. when i enter something and hit return, it adds a new line to the html file as well as <a name=END></a> tag (there is only one END tag at the end of the file)
I then request top frame to reload and goto END tag.
sometimes it works, sometimes it won't (IE). Is this normal ? Is it Frame related?
i use this script, and its working so far. except i want the element to stick to the bottom not the top..

i already tried to rename some words to bottom, but this doesnt work (ie iebody.scrollTop to iebody.scrollBottom)
I am trying to write in AJAX something similar to how Bing does the image search, where when you reach the bottom of the page, it loads more images. I can make it load my content once, but after that it just loads the content into the same div, not adding it to the existing page. Here is some of my code:
At the bottom of the main page I have:
<div id="results"></div>
My AJAX response is:
document.getElementById('results').innerHTML = xhr.responseText;
and my AJAX php file just echo's back a line of text.

View 9 Replies View RelatedI am looking for a javascript function that can log the following information for each pageview:
1. The total page rendering time (not php script execution time, but the time at which the entire page is rendered from the user's perspective - all images loaded, ads served etc)
2. The URL of the page
3. The browser used to access the page
4. The country the page was accessed from
The script should then store the information in a database via an AJAX call after it's been collected.
It sounds like a tall order, but it will help me get a picture of how fast or slow my site feels depending on where you live (e.g. how far you are from the server), what browser you're using, and which pages are the slowest to render (keep in mind this is not script execution time or query time, but literally the time at which the page starts to render, to when it finishes rendering).
I have a single webpage that contains information on all 50 U.S. states. There are 50 links at the top to jump down to the state you want, and at the bottom of the information for each state a Back to Top link.
I'm making the Back to Top link into something more complex, and it will require three or four lines of code.
So that I don't have to repeat the code 50 times, and create a burden when I need to edit it, I want to place it in a .js file and call it x. Then below the information for each state I'll simply have:
Does calling code from a .js file 50 times slow down the page load? Which method would load faster?
A website I've been working on has a black bar across the bottom. Under some conditions, however, there is a gap between the bar and the bottom of the page -- white for the body. The conditions vary between browsers and OSes. To keep things simple, I'll describe what happens with my principle development environment -- Chrome under Ubuntu.
The main body of the website is fixed width, centered against a neutral background. If the browser window is narrowed so that a horizontal scrollbar appears, the gap appears.
I have tried various things to find the gap so I can move the bar down or whatever but nothing seems to work. I tried using the document height but I found that it is greater than the actual display area which probably means that it is including something not visible (which is fine) but how do I reliably determine the extra? Or is there another solution I should be looking at (I won't bother listing all that I have tried)?
Not sure where this needs to be asked but i figure its javascript. I am wanting the page to snap to the bottom (scroll all the way to the bottom) on page load only. Allowing the user to scroll up without auto snapping to the bottom again. Is it possible to do this ?
