Array Displays Input Info And Word Undefined
Apr 5, 2011
The form allows users to enter there details, and when they click on the signup button the following is suppose to happen
1. Thank you note for signing up is displayed, including details they just entered
2. The details entered are stored in an array
3. When you want to view all signups you can click on a signup button and all details are shown
4. The form resets and clears all input fields
I have a form that allows input and functions that validate input, store input, and shows the input and html for the design layout. [code] The two buttons are called signup and members [code]When i run it i can enter all the details and click on signup all the details are still there and then i click on members and it shows all the details i have just entered along side the string signup but it also displays the words 'undefined', so I think there are problems with the array.

I know that we can split() a string into an array, if we have a string in an input field like this, "javascript rocks"
what if there is only one keyword in the input field?
for instance, it is only a word - "javascript"?

I keep getting <undefined> when I alert out the value of my array 'fadeimages1'. Using php/mysql I retrieve filenames from a directory and create <INPUT> fields to store the filenames. In the javascript portion of the code, I use getElementsByName() to retrieve all of the <INPUT> fields. I then declare an array, 'fadeimages1'. Next, using a for loop I try to copy the values from the <INPUT> fields into the array 'fadeimages1'. When I alert out the length and value variable for each <INPUT> field, I get the correct filename, but after trying to store the value into 'fadeimages1' array, I get value is <undefined> when I alert it out. BTW, the following code uses 'fadeimages1.push()', but I also tried 'fadeimages1[i]=...'. Both result in <undefined> values.

var arrAuth=new Array();
var linkArray = [];
function init(){
var xmlDoc = "";
window.ActiveXObject ? xmlDoc = new ActiveXObject("Microsoft.XMLDOM")

I have a multidimensional associative array in JS which contains category information for a navigation. It's actually set up through PHP, which pulls the info from a database then translates it into JS. I know it's set up correctly since I can see it in the source once the page is rendered. However, accessing this array causes external JS code (from my Slimbox files) to be displayed in the nav. It's as if the array is set up right, but accessing the elements brings in Slimbox code as the elements. It's very strange. You can see the effect here.
It's the secondary nav under Home, Featured Items, etc. Each token that is clickable is separated by an asterisk: [URL]. Notice the other page's navs work great! Try the jewelry nav on the Home page and the categories are set up fine. This is because other pages do not link to Slimbox. (And no, the site aint pretty because I wanted to get the hard stuff working before I work on the look). I've heard of jQuery interfering with Slimbox and Lightbox, but my nav is not using jQuery!

Way back in the day I did some old school HTML....but after many years not touching a web page I've kind of been thrown straight into the fire with some "wish list" items I'm trying to figure out. I've done plenty of searches and somewhat have an understanding of some of the basics of what I need to do...but I'm not the least bit comfortable with Javascript (I'm just assuming that this the language most applicable to what I'm looking for - and after the experience of my one day crash course with PHP I knew I needed to turn to some experts.
Okay I have a rather large web (about 150 pages) of historical transcriptions created with XHTML (with PHP headers and footers embedded). Generally speaking, I don't much like web pages that have right-click disabled and various other protections in place.....but I'm also the sort to obsessively cite my source material and give proper credits....as a researcher who's hard work has been plagiarized and passed off as the fruits of someone else's labor, I wholly understand why many are inclined to put such walls up.

i'm building a website at the moment with a user registration form. something i struggle with everytime is the best way to give feedback to the user (e.g. further instructions for a particular field or error messages).I saw a very nice execution of this recently at this site. /user/register - this looks to be a custom job, but i'm curious is the open-source or even paid plugins that do a similar thing.

I am working on a project that requires me to insert info in input boxes (2 input boxes to be specific, firstname, and last name are the two) and transfer that info into a <select> field when the button is clicked. So, let's say in the first input box which is first name I type Tom and in the second input box which is last name I type Smith. When I click the button I want the first and last name to appear in the select field as an option. Now, i tried researching about adding/removing options for the select field, but nothing on getting info from input boxes to put it as an option in <select>.

var allProductIDs = [5410, 8362, 6638, 6758, 7795, 5775, 1004, 1008, 1013, 1014, 1015, 1072, 1076, 1086, 1111, 1112, 1140]; lastProductID = 6758;
for some reason I get a -1 or I guess which is equivalent to not found for this:
alert(allProductIDs[allProductIDs.indexOf(lastProductID));
I can't figure out for the life of my why because it should find 6758 and that would be index 3. If it's index 3 then I should get back 6758 I would think.

I have a homework assignment which is pretty simple. It is a grade calculator that uses arrays to gather the grades from the user. This is what I have for the problematic section:
var homework = new Array(2);/* The grades entered by the user for Homework 1, 2, and 3 */
var project = new Array (3);/* The grades entered by the user for Project 1, 2, 3, and 4 */
[Code].....
My problem is the document.write portion of the code, where it is supposed to return either homework[0], project [0], or exam[0], it instead returns undefined. There is no problem with any other subscript. And yes, it does successfully prompt me for each of the [0] subscripts in the first part of the code. Am I just missing something that is right in front of my face? Does all arrays not start with the [0] subscript?

I'm just starting up in web design and I have an interesting challenge that I'm hoping can be solved w/java script. I have a site with an application form. When the form is to be submitted, the form data needs to be emailed to the correct person to handle that particular application. However, that can't be determined by anything specific in the form. It can only be determined by the link that they clicked on to get to the form. I really don't want to have 22 identical forms with just a different EmailTo addie, which is what the previous site developer did. Someone please tell me this can be done w/java script? If not w/java script

I am working on a very simple code to determine the highest value from an array and also use parallel arrays.
The problem I am having is, when I try to invoke the parallel array namesArray it returns undefined.
I have coded the function so it can be used to find the highest value in more arrays as this is only the beginning of my code. Im not sure if this is what is causing the problems but I have a feeling it is code...

I'd like to create a quick and dirty validation method for a form. It's not meant to be very secure.
The way I picture it working is this - there is an input field that asks for a password. If the user types in the password correctly, the "submit" div tag will change from "none" to "block". , which will display the submit button. I just am not familiar with JS enough to know if that's possible.
Here's what I'm starting with:

What I am trying to do is build a script that will read through an array of words and compare another word to the list to find where it would be placed alphabetically; between which two words would my word go.
Here is what I have come up with so far which doesn't work with words shorter than the shortest word in my list, or words spelled like the shortest word in my list except having a few more characters, plus more various issues.
Example: My list
If I use keywords "apex," or "as", this script fails.
What can I do to fix my code...

function loadSecondaryNetworks() {
var secondaryNetworks = new Array('13','14');
var select_list_field = document.getElementById('network');

value = value.split('-');

this code is supposed to display and load a secondary drop down menu if a particular ID(13 OR 14) is selected from the first dropdown. it works fine for 14, but not for 13. the "test" alert displays for both 13 and 14, but the second drop down only appears when selecting ID 14. I changed my array to ('13','14','13') and then it worked for both 13 and 14. is there something i am not aware of?

I use ASP to write the arrays at the start of my page:
<script language="Javascript">
var ArrManu1 = new Array();
var ArrManu2 = new Array();
var ArrManu3 = new Array();
[Code]....
...to populate the second dropdown box. However, when the user selects the first option in the first dropdown box (therefore making the variable "Co" equal to 1), ((ManuArr[Co-1])[i-1]) is "undefined" - why doesn't it add "Bell" to the dropdown?
