can any one guide me i am new to programming

Thanks in advance!!!

Ok, I would post my entire data here but then yall would be reading insane amounts of script. I've got a div content jquery slider on my site I am making and it works beautifully in all browsers(took me a while). Then, I decided why not have it where when people click on a "read more" link that it pops up a box, instead of directing to the new page, and displays the contents of a div. It would not work at all. My question is there a possible way to do this?

I have gotten my script to do exactly what I want it to do with one exception. I have some thumbnail images that people can mouse over and the actual image is 100px by 75px. That is what I use for my thumbnail and they reside in www.website.com/images/thumbs/image1.jpg. I have the large version of the image that resides in www.website.com/images/image1.jpg. Its actual size is 640px by 480. When I mouse over my thumbnail, I don't want the thumbnail to appear for the larger image, I want the large image to appear instead? Let me know if you need ellaboration. Any help would be great! Thank you.

Javascript
Code:

   <script language="JavaScript">
function Change_Big_One(thumb){
document.getElementById('BigOne').src=thumb.src.replace("_th","")
}
</script>

HTML THUMBNAIL
Code:

<div><img src="https://www.website.com/images/thumbs/image1.jpg" class="thumb" onMouseOver="Change_Big_One(this)"></div>

HTML LARGER IMAGE
Code:

<div><img src="" id="BigOne"></div>

QUESTION 1:

Hello. I would like to know if this is possible with Javascript, and if yes, if someone can please provide me with the code or point me in the right direction.

Let me start of by saying that this is for an eBay listing. I know that they accept basic / limited javascript and if what I am asking is possible, I hope that it can work on eBay listings.

I would like to know if it's possible to determine the dimensions of an image with Javascript from an Image url, and to then resize it or not based on the the size of the image.

So, let's say this is the URL: www.adomainname.com/image.jpg

and let's say that image is 1400 px x 1400 px. I would first like the javascript code to detect that size. I also would like the maximum dimension for any side of the image to be 600 px. If both sides of the image are over 600 px, for both sides to be reduced proportionally to 600 px or lower. If any one side of the image is larger than 600 px, the image is to be resized to 600 px or lower. If both sides are under 600 px, the image is to not be reduced. It would also be nice if it can detect whether the image is portion or landscape based on I guess the larger side, because an image at 600 px in height might be too big, but in width might be o.k.

So, in this example (the 1400 px by 1400 px), the image is to be resized to 600 px x 600 px.

For an image that's 300 px x 500 px, it should remain as such.

For an image that's 400 px x 700 px, it should be resized to 400 / (700 / 600) px by 600 px, which is approximately 343 px x 600 px.

I have looked a bit into this and I see things being mentioned about the image being loaded first completely on the screen, or about using server side language like PHP, and so on, but like I said, keep in mind that this is for eBay, and so I am limited.

Note: The part that I am most interested in is in being able to detect the size / dimensions of the image.

QUESTION 2:

On a side note, does anyone know if it's possible to have a Javascript enlarging function for images, in which when one clicks on an image, it is enlarged, but either in a popup window that's smaller than the one behind it, and possibly centered, or by making the background go dark and then bringing up the enlarged image (is the latter done with Javascript; I have seen this effect for a while now and have always wondered.)

Hello,

I am working on a page that has a jQuery full browser BG image and I am trying to also utilize a MooTools gallery. There seems to be some interference between the two JavaScripts as only one works (whichever one is last in order in the header of the HTML document).

I am a complete novice with JavaScript so if anyone could help that would be great.

Thank you in advance.

I can't really get any help over on the greasemonkey forums so hopefully I can get some needed help here.

My goal with a script I am writing is to remove signatures from a forum I am a part of. Some of the people abuse it with half a page of stuff and it's out of control. So here is what the HTML source code for it looks like

Code:

<hr size="1" noshade>I have been trying to set my attendance to the all star games but when I do a game search on the map it is showing no games at all.

The very bottom where it has the 'span' tag and it says "SEC Champions" is where the Signatures are located. I want to completely remove that using my script and this is what I have right now

Code:

function sigRemove() {
	var sigs = document.getElementsByTagName('span');
	for (var i = 0; i < sigs.length; i++) {
		sigs[i].style.display = 'none';
	}
}

I know it's incomplete but I only want to remove that bottom span tag and everything inside of it and not every span tag on the page. Please help and I apologize for the long post

Hello,

I have been using interstitial boxes for quite a while and have never had a problem. I was required to create an interstitial box this week. When the home page is display in Firefox and Safari, the interstitial box displays right away as it is supposed to do; however, it will not display in Internet Explorer 7 unless you refresh the screen.

Is this a known problem? Is there a way of correcting this?

Thank you for your help, Elbee

Hello there, I'm an IT student that recently started to learn JavaScript. I'm trying to write a code that starts with a prompt inputs a number like n. Then the code will ask another n prompts for data input. For example I will input 5 for first prompt, code will ask for 5 more prompts for input. Can't figure out how to do it

I want to create several pages (they can be text or html) with basic informatons for css formatting.
example:
<div class="appname"
name: this app
<div class="appdetails">
Version: 1.0
Date: 1/1/2011
Description: this is an app
</div>
</div>

I want to be able to save several of these and load them into a web page where they are formatted and displayed.

This needs to be a client side solution so that I can be able to access this offline.

Any suggestions?

Edit: so far I have tried this but I am not sure about it.
<object type="text/html" data="app1.html">

Hi guys, I am working with a plugin calld Hashslider which is a fairly simple div slider.

Here is the code for startrs Code:

// hashslider v0.9 by manuel huegel, copyright 2010
// mgoys.com


$(document).ready(function(){
					   
//get width and height of the wrapper and give it to the UL	
	var wrapperwidth = $('#slider').width() *  $('#slider ul > li').size();
	$('#slider ul').css('width', wrapperwidth);
	var wrapperheight = $('#slider').height();
	$('#slider ul').css('height', wrapperheight);	
						   
						   
//set my li width
	var width = $('#slider').width();
	$('#slider ul li').css('width', width);

//set my counter vars
	var counter = $('#slider ul > li').size();
	var decount = 1;
	var autocount = 1;
	
//create my number navigation
	var createNum = 1;
	$('#numbers li:first-child').html(createNum).addClass('activenum').attr('id', 'id1');
	while ( createNum != counter) {
	$('#numbers li:last-child').after('<li>  </li>');
	createNum++;
	$('#numbers li:last-child').html(createNum);
	$('#numbers li:last-child').attr('id', 'id' + createNum);
	}
	
//get my number-width (number navigation should always be centered)
	var numwidth = $('#numbers li:first-child').width() * $('#numbers li').size();
	$('#numbers').css('width', numwidth);


	
//slide the button to the next item
function goNext() {
	if ( decount != counter) {
	$('#slider ul').animate({ left: '-=' + $('#slider').width() }, 400, 'swing', function() { });
	$('.activenum').removeClass('activenum').next().addClass('activenum');
	decount++;
	window.location.hash = decount;
	}
}

function goBack() {
	if ( decount != 1) {
	$('#slider ul').animate({ left: '+=' + $('#slider').width() }, 400, 'swing', function() { });
	$('.activenum').removeClass('activenum').prev().addClass('activenum');
	decount--;
	window.location.hash = decount;
	}
}

//make the number clickable
$("#numbers li").click(function() { 
	//$('#info4').html( $(this).html() ); 
	var clickednum = $(this).html() * - $('#slider').width() + $('#slider').width();
	//$('#info4').html( clickednum );
	$('#slider ul').animate({ left: clickednum }, 400, 'swing', function() { });
	$('.activenum').removeClass('activenum');
	$(this).addClass('activenum');
	decount = $(this).html();
	window.location.hash = $(this).html();	
});


//thaths the hash-shizzle
if ( window.location.hash != '') {
//get hash, scroll to position
	var hashnum = window.location.hash.substr(1) * - $('#slider').width() + $('#slider').width();
	$('#slider ul').animate({ left: hashnum }, 0, function() { });
//set counters to position
	decount = window.location.hash.substr(1);
	$('.activenum').removeClass('activenum');
	var hashname = window.location.hash.substr(1);
	$('#id' + hashname).addClass('activenum');
}
	
//get my clickers
$("#right").click(function() { goNext(); });	
$("#left").click(function() { goBack(); });	


//get mousewheel function
$("#slider ul").mousewheel(function(event, delta) { if (delta > 0) { goBack();	event.stopPropagation();event.preventDefault(); } });
$("#slider ul").mousewheel(function(event, delta) { if (delta < 0) { goNext();  event.stopPropagation();event.preventDefault();	} });







});

As you will see the current code loops through all of the slides, and when it reaches the last (or first) the previous and next links become unclickable. I would like to go a stage further than this and make them dissapear entirely.

I don't know how to do this or even to start, I dont even know what function to edit.

Please help guys.

Thanks in advance

Hi,
Well this plugin stops working after completely loading the flash content or game. I did a few changes to it but still, it won't show the game after completely loading the flash.
Can someone tell me what's wrong?
Here is the link to live working example http://files.cryoffalcon.com/Piecema...s/testing.html

Hello.

I'm creating a simple auto updating script based on PHP and using jQuery to set the interval to 1000 miliseconds. It works in FireFox, as the only one I've tested so far, but in Internet Explorer (Version 7 right now, didn't test others) it just freezes and doesn't auto update. Doesn't auto update either if I refresh the page, so something's messed up here.

I'm using the same way of auto updating on other things, such as a chat-page - works on those in all browsers, so I'm kinda on a lost track here.

Here's the JavaScript/jQuery:
Code:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
function loadContent() {
	$('#count').load('counter.php', function() {
        setTimeout("loadContent()", 1000);
    });
    return false;
}
$(loadContent);

And this is what I put on the body of the page:
Code:

<div id="count"></div>

Can anyone see what my problem is? And any workarounds for this?

Hello. Is it possible to use java script to direct users to different page depending on their username login and password? And if so, what is the script?

The website i am creating is for a conference my school is hosting. What I want to do is give the username and password for each delegation to use; once they log in, they will be directed to a page which contains information pertaining only to their delegation.

Right now, this is the script I have, but it only directs to one page, which is "user1.php". I want to be able to direct user2 to user2.php, user3 to user3.php and so on.

<?php
$usernames = array("user1", "user2", "user3", "superman");
$passwords = array("pass1", "pass2", "password3", "supermans password");
$page = "user1.php"

for($i=0;$i<count($usernames);$i++){
$logindata[$usernames[$i]]=$passwords[$i];
}
if($logindata[$_POST["username"]]==$_POST["password"]){
session_start();
$_SESSION["username"]=$_POST["username"];
header('Location: '.$page);
exit;
}else{
header('Location: login.php?wrong=1');
exit;
}
?>

Any help would be greatly appreciated. Thanks!
