JavaScript - Javascript Coding Help Needed

I have a code that I implemented on my site. I was wondering if there was a way to had an active link within the 'blurb' section? I'm not familiar with Javascript...

var blurb = new Array();
blurb[0]="Text 1"
blurb[1]="Text 2"
blurb[2]="Text 3"
blurb[3]="Text 4"
blurb[4]="Text 5<br>More text<br>Add a link"
blurb[5]="www.link.com"

for (i=0; i < aryImages.length; i++) {
var preload = new Image();
preload.src = aryImages[i];
}

function swap(imgIndex) {
document['imgMain'].src = aryImages[imgIndex];
TheText = blurb[imgIndex];
document.getElementById('blurbarea').innerHTML=TheText;
}

Any help would be great!!

I am an amateur web designer and could really use your help.

I'm working on a test page right now (http://www.piscatawayacres.com/test.html). I'm trying to have 3 effects going on at the same time, but due to my inexperience with Javascript (I, in fact, copied and pasted most of it), I can't get them to work. To complicate things, my test page works to a certain extent, but when I copy and paste the coding to other pages (like alpacas.html, sheep.html, goats.html, etc.) it ceases to work. I have no idea why it does this.

The 3 effects I want to have work:

1. Javascript rollover buttons.

2. A Javascript slideshow--the square picture above the buttons should be changing.

3. I want the image and the buttons to follow the user down the page as they scroll. For some reason though, the buttons (on the couple of pages they work at all) cease to work except at the very top of the page or the very bottom, but not in between.

I've been struggling with this obstacle for a long time, so I would greatly appreciate any help someone could give.

Thanks so much for your help.

P.S. I want to emphasize that some of the coding works on the test.html page, but WON'T work when I copy and paste it elsewhere. I can only assume it is because of conflicts with the coding. I know my coding is not flawless....

Hi, I'm fairly new to javascript & am trying to learn it using best methods. I have been using various books & some video tutorials, such as lynda.com. I've noticed when I do google searches for example tutorials, 9 times out 10, the javascript has been coded into the html file. As a newbie I find it takes a very long time to redo the coding into the separate .js file. And if the coding is relatively complex (and most of it appears that way to someone new to this) I can't get it too work using a separate file for the javascript. I wanted to ask anyone very familiar with this, their suggestions regarding good places for tutorials where the .js file is separated. Apparently there are advantages to having it separate and it's considered best practices from what I've come to understand. Also most of the results from google searches pulls up out-dated coding and/or tutorials that suggest you should already understand what is being referred too. I'm trying to avoid learning it the wrong way. I'm willing to put in the effort, however I don't want to pick up bad habits. Any help is very appreciated. If this was not as clear as I intended it to be, please ask any specifics and I'll try my best to answer.

Hi Experts,

I'm new to this forum and need your help regarding javascript.

I am creating a roster for my team with a web interface.
Ex: A picture is attached for your reference

The time is in IST (+5:30)

I have created a drp down list which has PST, EST,CST time. I need to write a code so that whenever I select any of these times (PST,EST,CST, MST, IST) , it should automatically update the table. Please help.

Regards,
Indy

Okay, I am relatively new to Java and am going to be taking a class on it next fall. For now though, I am trying to code for a client I am currently working with and am hopelessly lost.

The client I am working with has an ecommerce site with Network Solutions which uses aspx. It allows you to code html and link to css, java (pretty much anything except php). The problem I am having is that they currently have their product descriptions coded in div tags:

<div id='alternatebg'>
<div id='detailsgreybox'><div id='alternatename'><p>Alternate Name</p></div></div>
<div id='pd2'><p>Not Available</p></div>
</div>

<div id='usebg'>
<div id='detailsgreybox'><div id='use'><p>Use</p></div></div>
<div id='pd3'><p>Chemicals</p></div>
</div>

What they want to happen is for the sections that have 'Not Available' as the answer to not show up on the live page. I have tried to use <ns:if condition="..."> but do not know how to call for it to see if the div says 'Not Available'.

Any help is greatly appreciated as I can not move forward until I can figure this out.

Hello, I'm new to this forum. I want to improve my ability to write JavaScript and am looking for a friendly place to find some constructive criticism and suggestions on my code.

This script does not have any practical use (that I can think of); it calculates prime numbers. It is just an exercise. I am looking for suggestions on all aspects from the CSS/aesthetics to the HTML and of course the JavaScript.

I posted the script here.

One definite thing that bugs me is the cursor is not in the text field when the page loads. Also it would be better if the user had the option of hitting the return key in addition to the submit button. Suggestions appreciated.

Code:

<!DOCTYPE html>
<html lang="en">
<head>

<title>Prime Number Calculator</title>
	<style type="text/css">
		form{
			width: 200px;
			border: solid 3px blue;
			border-style: double;
			padding:5px;
			text-align:center;
			background-color:#eee;
		}
		#title{
		
			text-align:center;
			border: solid 1px blue;
			background-color:#fff;
			margin:5px;
			padding:0px;
		}
	</style>
	<script src="jquery.js" type="text/javascript"></script>
	<script type="text/javascript">
		var candidates = new Array();
		function calculatePrimes(form){
  			var max = form.input.value; 
			
			//Check to make sure input is a number
			if(isNaN(max)){
				alert("Dude, you must enter a number!");
			}
			
			for(i=2; i<=max; i++){candidates[i]=i;}
			
			var i=2;
			for(i=2; i<Math.sqrt(max); i++){
				if (candidates[i]!=0){
					var j=i*i;
					while(j<max){
						candidates[j] = 0;
						j=j+i;
					}
				}
			}
			
			//Pull the primes out of the candidates
			i=2;
			var primesOut = "";
			for(i=2; i<max; i++){
				if(candidates[i]!= 0){
					primesOut = primesOut + ((i>2)?", " : "" ) + candidates[i];
				}
			}
			form.output.value = primesOut;
		}
	</script>
<head>
<body>
	<form>
		<h2 id="title">Prime-Number Calculator</h1>
		Check up to:<input type="text" name="input" size="5" value="100" \> <br />
		<textarea rows="5" cols="20" name="output"></textarea>
		<input  name="calc" value="Find!" type=button onClick="calculatePrimes(this.form)">

Hi,

I'm still in the early stages of learning Javascript so I'm not sure how (or if it's possible) to do this. I know HTML, CSS, etc... just not too familiar with Javascript. Here's the deal.... I run a website that features a chat room written in Perl for CGI. The chat room will automatically email a user their password if it's forgotten but there is one issue.....it does not have the "Forgot Password?" link. To achieve the Lost Password page, the user must enter an invalid password FIRST on the login screen, otherwise they cannot get to that option and are often requesting assistance.

What I had in mind was an easier way for the user to get their password since new novice members are not sure how to get to the lost password page. I'm not trying to edit the Perl code for the chat, but I wanted to build a "Forgot Password?" page using a Javascript code that will automatically take their username from the "username" login field and direct them to the lost password page which would be "chat2.cgi?action=send_pwd&name=..."

I'm sorry if this is confusing, I'm not sure that I am explaining this right. When the user enters an invalid password, it takes them to the lost password page which contains a link "lost password" and will automatically email them their login details when clicked on. When they click that link, the URL contains the string "chat2.cgi?action=send_pwd&name=username"

What I would like to do is put a link on the login page (like most normal chat rooms have) that says "Forgot Password?". When clicked on, I want it to take them to a page where all they have to do is enter their username in a form and click Submit, then have a Javascript code automatically extract their username from that field and insert their username automatically to the end of that URL (chat2.cgi?action=send_pwd&name=...) where ... would be the name extracted from that form field. This would result in the browser taking them to that URL which would trigger the chat to automatically email the password. Can I do this with Javascript?? If so, any help would be greatly appreciated!

Hello all out there I am going to post this in 2 separate views.

I am working on an assignment from this link

if u scroll down to case 1
is what I am working on

included in the case are 2 other files as to the one i have to work on

i used all the proper steps and instructions and i think I have the correcting coding for my form

however my program still does not work

here is the exact code i am using
let me know if anyone sees any errors, as I am convinced i have it correct?

I'm working on a new custom theme for my WordPress based site, and up until now I've been using the following PHP code to color code links based on whether the post was in the "Wii" category, "Xbox" category, or "PlayStation" category:

PHP Code:
<li>
    <?php if (in_category(3) ) { ?>
    <a style="color:#990000;" href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a>
    <? }elseif (in_category(4) ) { ?>
    <a style="color:#669900;" href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a>
    <? }elseif (in_category(7) ) { ?>
    <a style="color:#0099cc;" href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a>
    <? } else { ?>
    <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a>
    <? } ?>
</li>

Thing is, I've now installed a plugin called "Recently Popular" that logs all visits and can output which posts were viewed the most in the past X days/weeks/months/etc. and the author has it set up to only allow HTML formatting via this line:

PHP Code:
<?php get_recently_popular(1, 'WEEK', 5, 0, 0, '<a href="%post_url%" rel="bookmark" title="%post_title%">%post_title%</a>'); ?>

I've tried sticking PHP in the line, but it only takes HTML. I've tried sticking one of these lines in each of the conditional statements above, but realized that this line outputs the entire "Recently Popular" list, not just one item - so everything would end up being the same color still. I contacted the plugin author, who said that without hardcoding there's no way to get around this via the plugin, but that outputting it normally and running it through JavaScript might give me a way to apply CSS styling to it after it's been rendered.

I'm not experienced with JavaScript, unfortunately... does anyone know how I can do this?

I'm working very hard to create a dynamic web-site for use in the education sector using server-side php/MySQL and client-side HTML with javascript.
I have a logon page (index.php) which looks to see if the cookie 'mylogon' is set with the value 'Again'. This cookie is set when the PHP element on the server detects an invalid username/password combination. If so I have a javascript function (see below) call from the HTML <body onload="check_invalid_user()">

I know that the function Get_Cookie is working ok and that the javascript variable 'again' has the value 'Again' in it and has a length of 5. The alert function is not executed though.

function check_invalid_user()
{
again = Get_Cookie('mylogon');
// document.write(again);
// document.write(again.length);
If (again == 'Again')
{
alert("User-id and/or password incorrect -- Please re-enter");
}
}

Any help would be appreciated Many thanks in advance. (Yeah you guessed it I'm new and raw to this stuff.

How to create a popup blocker with javascript? I am looking for solution to open Enquiry form [Ex: send-query.php] through javascript linking. How can I do that?
And how to display a popup blocker message like in the attached file?
This is the url of my pop up image: http://www.rhapsody.com/thompson-squ...mpson-square-2
[When you click on play button then if you have popup blocker enabled you will get popup blocker message from the site]

I have a script that works good, but it says undefined underneath, this must mean an error. But I cant work out how to get rid of it.
This is the html it is a transistional XHTML doc type.
Code:

<div id="slidedom">
<script type="text/javascript" src="js-files/slider.js"></div></script>

Then I have the js file which I will have to post all of as I am not sure of the error bit.
Code:

var variableslide=new Array()

//variableslide[x]=["path to image", "OPTIONAL link for image", "OPTIONAL text description (supports HTML tags)"]

variableslide[0]=['images/sign-1.gif']
variableslide[1]=['images/sign-3.gif']
variableslide[2]=['images/sign-4.gif']

//configure the below 3 variables to set the dimension/background color of the slideshow

var slidewidth='188px' //set to width of LARGEST image in your slideshow
var slideheight='60px' //set to height of LARGEST iamge in your slideshow, plus any text description
var slidebgcolor='#FFF'

//configure the below variable to determine the delay between image rotations (in miliseconds)
var slidedelay=3000

////Do not edit pass this line////////////////

var ie=document.all
var dom=document.getElementById

for (i=0;i<variableslide.length;i++){
var cacheimage=new Image()
cacheimage.src=variableslide[i][0]
}

var currentslide=0

function rotateimages(){
contentcontainer='<center>'
if (variableslide[currentslide][1]!="")
contentcontainer+='<a href="'+variableslide[currentslide][1]+'">'
contentcontainer+='<img src="'+variableslide[currentslide][0]+'" border="0" vspace="3">'
if (variableslide[currentslide][1]!="")
contentcontainer+='</a>'
contentcontainer+='</center>'
if (variableslide[currentslide][2]!="")
contentcontainer+=variableslide[currentslide][2]

if (document.layers){
crossrotateobj.document.write(contentcontainer)
crossrotateobj.document.close()
}
else if (ie||dom)
crossrotateobj.innerHTML=contentcontainer
if (currentslide==variableslide.length-1) currentslide=0
else currentslide++
setTimeout("rotateimages()",slidedelay)
}

if (ie||dom)
document.write('<div id="slidedom" style="width:'+slidewidth+';height:'+slideheight+'; background-color:'+slidebgcolor+'"></div>')

function start_slider(){
crossrotateobj=dom? document.getElementById("slidedom") : ie? document.all.slidedom : document.slidensmain.document.slidenssub
if (document.layers)
document.slidensmain.visibility="show"
rotateimages()
}

if (ie||dom)
start_slider()
else if (document.layers)
window.onload=start_slider

I have taken out the credit, as I have changed it a bit, but will reinstate it later on. All I really need to know is how to define it in the XHTML maybe. Can anyone help?

Pretty pretty please help me with this I am running out of time and pulling my hair out with this whole thing.
Thanks a million in advance!
Rhonda

new to JavaScript, simple question...

question: how do i determine an output from a prompt to be bold?

e.g. a user enters "hello" and the output printed from the prompt becomes bold


one=parseFloat(prompt('enter number',0.bold));

Hi,

I'm trying to get my head around JS, but not too successfully yet.

My objective is probably simple (but not to me ): to have a form where visitors enter 12 separate digits (ideally in minutes & hours, but am happy to use decimals), and the average of these (to two decimal points) is returned as document.write is it? - along with other text, to make a complete & coherent sentence, including the average of the 12 numbers.

Does anyone have any code convenient that could do this?

Thanks,

LJ
