JavaScript - Show The Loading Box At The Centre Of Screen
I have the div box
Code: <div id="ajax_loader"><center><img src="/css/ajax-loader.gif" alt=""/></center></div> Quote: #filter { display: none; position: absolute; top: 0%; left: 0%; width: 100%; min-height: 900px;; overflow:visible; background-color:#000; z-index:900000; opacity:0.5; filter: alpha(opacity=50); } #ajax_loader{ display: none; position: absolute; top: 50%; left: 50%; z-index:900001; overflow: visible; height:40px; width:60px; background-color:white; vertical-align:middle; padding-top:10px; border:1px solid black; } The problem when the page loads then my content height is around 2000px. So the animations loads on the center of screen but on the upper portion of page which is visible when the page loads. bUt my submit button is at the bottom of page so when i click submit the ani,atiosn stays at the top . I want the animation to load on the screen which is currently visible not which is at the startup Similar TutorialsHi, I am an asp.net developer and I wanted to display user popup (kind of) which freezes the screen so that user won't click anything else on the screen. There are some predefined controls in asp.net, but I wanted do this using Javascript. Where can I find a sample with code? Thanks There is a stand-alone, full-screen slide show code published at http://www.javascriptkit.com/script/...ow/index.shtml I would like to know how to set the size of the show to less than full-screen, and how to integrate the show with other web content. Dear Experts, I am very new for javascript so I am not even sure it is possible or not. The situation is like this, I have a page, which is actually a photo gallery with a table having 3 rows. First row shows the full screen size pic. Second row displays the Caption of that image and third row shows thumbnail view of six different images and the previous and next button. this is the sample layout: <table> <tr> <td colspan=8> Full size image will be shown in this cell </td> </tr> <tr> <td colspan=8> Caption of the image will be displayed here </td> </tr> <tr> <td>Previous Button</td> <td>Pic1 thumbnail view</td><td>Pic2 thumbnail view</td><td>Pic3 thumbnail view</td> <td>Pic4 thumbnail view</td><td>Pic5 thumbnail view</td><td>Pic6 thumbnail view</td> <td>Next Button</td> </td> </tr> My requirement is whenever the user click on the thumbnail view, which is in the 3rd row, the corresponding full screen size pic should open in 1st row of the table. As my photo gallery should be having more than 6 pics, lets take 20 pics, I want to show only 6 thumbnails in 3rd row at a time. Whenever user press "Next" button the 3rd row having 6 thumbnails should show other 6 thumbnails and previous button should show previous 6 thumbnails. I have a guess that it can be done using arrays, but how????? I have no idea. So please if you have any guesses it will be nice if you can post the entire code here as I will not be in a position to work on the hints given by you. Thanks in advance. Charles Hi all, this is my first post so forgive me for any errors but i'll try and give all the information i can. i use Xara Designer Pro and i have used a 3rd party software to create a html menu however i have a html loading screen on my site and the menu always appears on top of the screen and while the screen is loading, this is the only thing that appears on top everything else is fine, i have put this to the people on the xara forums and the opinion is that its probably the JS file that the menu is using that is telling it to appear on top. i was wondering what i should look for to determin this problem or if someone could take a look at it for me? i'll upload the JS here and see if anyone can help. my site is at www.pcevo.co.uk however you need to CTRL + F5 to refresh wihtout the cache to see the loading screen if you are on a fast connection.
Hello all, I have the following code to load a new html page into the 'new content' div once the user scrolls to the bottom of the page. It all works fine. No problems, except I would like it to pause for a moment whilst it is loading, and show a loading box div at the bottom of the screen as it loads the new content, just to give some positive feedback for the user. So the new div would sit in a fixed position at 'bottom:0px;' and have a loading image inside it. Is this easy to do? I am new to javascript so bear with me Code: alreadyloading = false;
nextpage = 2;
$(window).scroll(function() {
if($(window).scrollTop() + $(window).height() == $(document).height()) {
if (alreadyloading == false) {
var url = "page"+nextpage+".html";
alreadyloading = true;
$.post(url, function(data) {
$('#newcontent').children().last().after(data);
alreadyloading = false;
nextpage++;
});
}
}
});
The 'new content' is a div which is at the bottom of the page and is where the new content loads to! Thank you very much I want to have a screen (50% transparent white) pop up over an image on rollover with a button that, when pushed, will swap the image with a different one. Anyone know the easiest way to do this. The image is in a scrolling bunch of images similar to this: http://kellyperso.com
How do I show the default icon for pdf, doc, etc... else show the image? Code: Show the default icon for pdf, doc, etc... else show image.

All- I have a page coded that pulls files from a directory using PHP then sets them up using a Flash type player to stream the video. My problem is that I have to resize the video window for each computer I play it on. They all have different resolutions. I was able to use: Code: <script type="text/javascript" src="/jwplayer/swfobject.js"></script>
<script type="text/javascript">
var x = (+screen.width);
var y = (+screen.height);
if (x == '1920' & y == '1080')
{
var xn = 1440;
var yn = 900;
document.write(xn);
document.write(yn);
}
if (x == '1024' & y == '600')
{
var xn = 900;
var yn = 400;
document.write(xn);
document.write(yn);
}
swfobject.registerObject("player","9.0.98","/jwplayer/expressInstall.swf");
</script>
To pull out the current Resolution of the user and pass to a variable the resolution I want the video to be. Here is where the video code is Code: <object id="player" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" name="player" width="900" height="400">
<param name="movie" value="/jwplayer/player.swf" />
<param name="allowfullscreen" value="true" />
<param name="allowscriptaccess" value="always" />
<?
echo "<param name='flashvars' value='file=../Movies$full_dir.mp4 =../Movies$full_dir.jpg' />";
?>
<object type="application/x-shockwave-flash" data="/jwplayer/player.swf" width="900" height="400">
<param name="movie" value="/jwplayer/player.swf" />
<param name="allowfullscreen" value="true" />
<param name="allowscriptaccess" value="always" />
<?
echo "<param name='flashvars' value='file=../Movies$full_dir.mp4&image=/Movies$full_dir.jpg' />";
?>
<p><a href="http://get.adobe.com/flashplayer">Get Flash</a> to see this player.</p>
</object>
</object>
In the video part, where it says Height and Width, I just need to have it take the 2 variables i created depending on the resolution used. Variables xn or yn. Any ideas? Please Please help! been stumped on this all afternoon!! Thanks Defyer! I use a program that produce a graphic (imagine a sinusoid, more or less). There is no opportunity to obtain from the program an output of the coordinates of the points of this curve. I desperately tried a way to achieve this, for example using a program that transform a normal raster image in a vector, and after read the vector, but all this is not precise nor accurate. I wonder if there is a way to obtain this result. Bye Hi I have the code below which geocodes a postcode and returns a lat a long value. Its standard code from Google maps. I just want to print these values to a screen. I tried document.write(value) but this produces nothing. Any help would be greatly appreciated. Code: <script type="text/javascript">
var localSearch = new GlocalSearch();
function usePointFromPostcode(postcode)
{
localSearch.setSearchCompleteCallback(null,
function()
{
if (localSearch.results[0])
{
var resultLat = localSearch.results[0].lat;
var resultLng = localSearch.results[0].lng;
}
document.write(resultLat+resultLng);
//alert("Latitude: " + resultLat + "\nLongitude: " + resultLng + " q");
});
localSearch.execute(postcode + ", UK");
}
</script>
TIA Stew Hi there, Firstly my title may be a bit misleading as I don't i'm not sure how to do it. My situation is that I have a small piece of javascript that 'cycles' through a bunch of URL's (the URL's are reports produced by SSRS). The problem is that each time the javascript loads a new URL it has to generate the report, so I have a few seconds where the screen says 'Generating Report'. What I would like is a system that never displays the Generating Report, instead I would like to maybe pre-load the next report so it is ready to show instantly. Does anyone have any idea how to do this? Any help would be greatly appreciated. Cheers, Tom. Hi everyone, I am having trouble getting a loading bar to appear from my javascript. I have the following code in place Code: $(document).ready(function(){
$(window).scroll(function(){
var h = $('#footer').height();
var y = $(window).scrollTop();
if( y > (h*0) && y < (h*1.0) ){
$('#loading').fadeIn("slow");
$('#loading').delay(10000).fadeOut();
$("#portfolios").delay(1000).fadeIn("slow");
}
});
})
I have it so when the user reacher the 'footer' div of the page, new posts appear which are contained in the 'portfolios' container div. They appear fine but no loading bar appears... The loading bar 'gif' is in the 'loading div id'. There is a 'display:none;' in the css on the loading div and the portfolios div. Any reason why the 'loading' div doesn't display but the portfolios does? I want the loading gif to show whilst the 'portfolios' is loading basically when the user hits the bottom of the page. Any help would be appreciated! Thank you! Hi there I know this picture_viewr js is a fullscreen slide Would it be possible to set a screen size (700x500 e.g.) and then set a background color or the part that would be outside this window??? Thx a lot allberto http://www.alfaaudiovisual.com/pictu...er/ByB/ByB.htm Hi Guys, I would like to be able to change my webpage background image according to the screen resolution the user uses so: if screen resolution is greater than or equals to 1200*600 then background = mybackground.jpg no-repeat else background = #000000 THANKS A MILLION! I have been using wz_tooltip and have a big tooltip that needs to be opened at the top of the screen, not by the cursor in order to be read. What do I add to the script to do this? Thanks, Wina I am using this javascript code to detect screen size and display an alternate css. Code: if (screen.width<1600)
{
document.write('<link rel="stylesheet" href="<?php echo $path ?>/css/templateadjust.css" type="text/css" />');
}
This works fine in FF and Chrome but doesn't seem to work in IE. Any idea why? Ok. My first fish is swimming across the screen perfectly fine. He starts from the left side and goes to the right side. But for the second fish, he is on the right side and he won't swim to the left side. How do I get him to start swimming? Then he will stop after the interval of 80 reaches like the left one and then start over from the left to the right. Here is my code: Code: var fish1Position = 0;
var fish2Position = 0;
horizontal = new Array(80);
var fillPosition = 10;
for(var i = 0; i < 80; ++i) {
horizontal[i] = fillPosition;
fillPosition += 10;
}
horizontal2 = new Array(80);
var fillPosition2 = 10;
for(var i2 = 80; i2 > 0; i2--) {
horizontal2[i2] = fillPosition2;
fillPosition2 = fillPosition2 - 10;
alert(fillPosition2);
}
function fish1Swim() {
document.getElementById("fish1").style.left = horizontal[fish1Position] + "px";
++fish1Position;
if (fish1Position == 79)
fish1Position = 0;
}
function fish2Swim() {
document.getElementById("fish2").style.right = horizontal2[fish2Position] + "px";
++fish2Position;
if (fish2Position = 79)
fish2Position = 0;
}
function startSwimming() {
setInterval("fish1Swim()",100);
setInterval("fish2Swim()",100);
}
Hi friends, I have a dropdown menu,when i select one item from the dropdown menu,i want a checkbox to be created on the screen.How do i achieve this? Thank You Madhusudan Hi nerds, We have some problems with some javascript code. We are creating a new button like the ones known from addthis/sharethis and would like the same behavior as there popups. We have tried by putting together some different scripts, and the action is about right. We do still have one problem, and that is the position of the popup. If the button is placed at the right site of a website, it floats out of the screen, making scrollbars. Also it don't have same position behavior in Firefox, IE, Opera ... The button can be seen he http://www.langthis.com The code related to this problem should bed this: Code: function move_box(an, box)
{
var cleft = 0;
var ctop = 0;
var obj = an;
while (obj.offsetParent)
{
cleft += obj.offsetLeft;
ctop += obj.offsetTop;
obj = obj.offsetParent;
}
var winW = window.innerWidth ? window.innerWidth : document.documentElement.clientWidth ? document.documentElement.clientWidth : document.body.clientWidth;
var winH = window.innerHeight ? window.innerHeight : document.documentElement.clientHeight ? document.documentElement.clientHeight : document.body.clientHeight;
if (cleft+box.offsetWidth > winW) {
cleft = cleft - box.offsetWidth - 30;
if (cleft < 3)
cleft = -3;
}
box.style.left = cleft + 'px';
ctop += an.offsetHeight + 8;
// Handle Internet Explorer body margins,
// which affect normal document, but not
// absolute-positioned stuff.
if (document.body.currentStyle &&
document.body.currentStyle['marginTop'])
{
ctop += parseInt(document.body.currentStyle['marginTop']);
}
if (ctop+box.offsetHeight > winH) {
ctop = ctop - box.offsetHeight - 20;
if (ctop < 3)
ctop = -3;
}
box.style.top = ctop + 'px';
}
If someone would be interested in rewriting the script, we would credit this in our about page. Else we would be thankful if someone just could help with the existing code. Best regards Langthis team Hi, I want a link on my website where when you press it, it print screens. somthing like, <a href=printscrn();">Print Screen</a> anyone any ideas? Simon |
