Array Undefined After Setting Equal To Values Of Several <INPUT> Fields
Apr 7, 2009
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.

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.

Basically, I am asked to set fixed height on a group of tabs. The tab that has maximum text will set the height for the rest of the tabs. The simplified version of the code looks like below:
<ul>
<li><a href="">Tab 1</a></li>
<li><a href="">Tab 2</a></li>
<li><a href="">Tab 3</a></li>
</ul>
Taking this example, I want to set the fixed height for <a> tag.

Ive attached a screen shot of the type of layout I have. I have two columns, the left column is straight forward single div, but the right may have up to three divs inside of it (there is an outer div called right-col which I forgot to shade in which wraps around div box1 and 2), and I would like the last div to extend so it is the same size as the div on the left (similarly, if the content on the right was longer then the left, then I would want the left div to expand). Ive attached a screenshot of what I mean. There are loads of plugins, that show you how to make two/three columns equal heights, but I have not found anything to show me how to make two columns in a div equal height to another whole column - hope that makes sense.

Is there a way that I could get id values of input fields that are inside certain divs and these divs have same class. For example say I have this code (simplified):
Code:
<div class="jep">Some label</div>
<div class="jep"><input id="20"></div>
<div class="jep">Some label</div>
[Code]....
So what I know is the class name "jep" so how to get all the input field id's that are inside divs that holds this certain class "jep" ?

I have just started learning JavaScript, so I do not know much about it at this moment. I need suggestion regarding validation of input values which are actually in an array. My HTML looks like this:
Link# 1: <input name="url[]" size="80" type="text">
Title# 1:<input name="title[]" size="80" type="text">
Link# 2: <input name="url[]" size="80" type="text">
Title# 2:<input name="title[]" size="80" type="text">
Link# 3: <input name="url[]" size="80" type="text">
Title# 3:<input name="title[]" size="80" type="text">
.
.
.
.
.
And so on. (up to 20)
User can add more input fields by adding "Add" button; I'm using JavaScript for that purpose. By default, only a couple of fields is shown. I want to validate these all fields using a loop or a number of loops, such that an alert appears if any field is left blank and also if any value in title[] array matches another value in that array and same for the second array url[] Examples of working would be something like this:
If Link# 1 is left blank: alert("Link# 1 is empty");
or
If Link# 2 is left blank: alert("Link# 2 is empty");
or
If Title# 1 is left blank: alert("Title# 1 is empty");
or
If Title# 2 is left blank: alert("Title# 2 is empty");
or
If Link# 1 == Link# 2: alert("Link# 1 is same as Link#2");
or
If Link# 1 == Link# 3: alert("Link# 1 is same as Link#2");
or
If Title# 1 == Title# 3: alert("Title# 1 is same as Title#3"); etc, etc.

is this correct
var mid = math.floor((0 + array.length)/2)
from here you could use array.slice to divide the array into two equal sized arrays?

When the user enter a value into the quantity input field it calculates the first amount another entry to the same field would calculate the second amount instead of the second input fields entry. The other input fields behave the same as the first one. How do I match the input fields to quantity? Here is the code.
<code>
<?php
include_once ("db.php");
//include_once("common.php");
?>

How would I go about creating a new arrary which consists of the values for every text input within a form? The array would need to be created dynamically when the function is called (by clicking a button or whatever). Is this possible?
So if the input fields looked like this:
<input type=text value=banana>
<input type=text value=pear>
<input type=text value=grapes>
An array like this would be created once i ran the function:
var values=new Array("banana",pear","grapes")

I have two forms with identically named arrays on each. I need to copy the values to the second form's array. Here's a simplified version of the HTML:
<form name="mainform">
<input type="text" size="10" name=firstnames[] value="Joe"/>
<input type="text" size="10" name=firstnames[] value="Bob"/>
<input type="text" size="10" name=firstnames[] value="Pat"/>
[Code]....
I'd like to be able to submit hiddenform with the firstnames array equal to ['Joe', 'Bob', 'Pat']. But I seem to be getting an awful lot of ['', '', ''] no matter how I go about it.

let me try to explain better what I'm trying to do. I'm a real newbie I don't know much javascript but I understand more or less the logic behind it... tell me if this solution should work and if you know how to do it please show me. [URL]... I need to make div#photo's width to match the total width measurement of all the images it contains. If you load the page and you don't touch the size, it will work fine... but that's not realistic. If I resize the page, which will happen often on this kind of page (I'm assuming), the whole thing goes haywire (try it, scroll to the last image and resize the page you'll see what I mean). What can I do? Is my idea the right solution? Am I not explaining this clearly enough? Let me know please, I'm desperate. I've been trying to get CSS to do this for me for 3 hours now. Nothing works.

I am having trouble with some javascript code that checks the first 2 letters of what the user inputs and whether it equals a certain set of characters. If the user for instance types in 'TT' in an input field, then i want the holding div to disappear, if anything else is typed in then this action wont happen. My code is below:
Code:
<script type="text/javascript">
function checkCode() {
var x=document.forms["myform"]["code"].value.substring(0, 2);
if (x == 'TT')
[Code]...
I believe the problem lies in the javascript line: "if (x == 'TT')", as the rest of the script responds but it just doesnt recognise whether 'x' starts with 'TT'

I have a draggable marker on my page that sets the value of a javascript variable when the marker is released.I want to submit this value to store it in a database however I cannot figure out how to pass this javascript variable as a hidden form field.Here is my code. I suspect this is completelyhow to make this "lat" value available to me after the form has been submitted.
Code:
<form name="myform" method="post" action="" >
<input type="hidden" name="lat" id="lat"

I have multiple fields in a form with the same name. Lets call the fields with the same name "junk_array". My first field of junk_array is a input type=hidden. All the others fields in junk_array that follow are type=text. I can reference this first hidden field in IE with document.form.field[0].value. In, fact my form works absolutely wonderful in IE 6. However, netscape 4.7 does not recognize my first field in the array as the hidden field. Netscape sees the first visible text field as the first field in the array, subscript 0. What totally and utterly perplexes me, is that, from a previous thread, I can do this and get 9999 back in an alert
box in Netscape and IE. So, this proves Netscape doesn't have some evil code that disregards hidden fields. I guess...
<body onload="alert(document.myForm.test[0].value);">
<form name="myForm">
<input type="hidden" name="test" value="9999">
<input type="hidden" name="test" value="8888">
<input type="text" name="test" value="6">
<input type="text" name="test" value="3">
</form>
I even copied these fields directly below the opening <form> tag in my form and both Netscape and IE see the first hidden field as as
subscript 0.
However, my form is much more complicated. I have tables within tables and about 30 other fields. In my form I cannot for the life of me get Netscape to recognize the first hidden field of junk_array to zed as index 0.
Somehow, If I make the first type=hidden fields visible, netscape does work nicely. Why when I toggle type=hidden to type=text does Netscape cooperate. What is happening here? Anyone else have this problem with hidden fields in Netscape? I could post the code to my form but it is
big.

I have been looking for the past 2 days for a script that I can add and delete table rows.
I have found a lot but so far all of them add an input field but I desperatly need a textarea or ideally a section of input fields.
I have tried to change the code from input to text area but none of them worked.
Have you come across to a similar script.
I would appreciate any contributions.
What I am trying to do is a page where the user will add their employees details so we can order business cards for them. So I have fileds such as, Name, Tel Num, Email, Cell etc.

I am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form.For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields.
