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.
Context: I have a a framed page which have two frames.First frame have two iframes and second frame also have two iframes. Each iframe have a form to add record. Each forms have some fields to enter data. To show the layout of the page, I have created a picture. Go through this layout picture at this link: [URL]
Problem: I have set the following javascript variables in the <head> tag of "leftframe.htm" which represents frame "leftframe".
<script type="text/javascript"> var studentFirstName = ""; var studentLastName = ""; [code]...
Now I want to set the value of these variable to the input box (text box) of these forms in different iframes.
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:
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):
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:
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.
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"); ?> <!-- To change this template, choose Tools | Templates and open the template in the editor. [Code]...
I got an unusual request form a client. I got a form and I have to get values from certain input fields and assign them as a value to a hidden field and then submit it through php.I'm using mootools (1.11). I was tinkering around that for a day and wasn't able to solve it. Here is the html:
Code: <div> <label for="primary_domain0">Primary Domain Name <span class="req">*</span></label>

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?
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.
Below is my code, please ignor the comments etc. its very basic. i have a set of data in a var. i am displaying the highest value in that set of data. however one of my sets of data the highest value has 2 occurancies so i want to display both. atm it just displays the first occurance of the highest value and then stops as opposed to all occurances. if you run my script you will see what i mean.
Code:I am having problems with the following. I am wanting to hide <tr> in my table (employees) and only show employees that are in the selected department (selected via dropdown box).I need to set a javascript array to a php array. I am looping and assigning the array and am wanting to pass a javascript variable as the index in php array. I have marked my problem lines in red. Thanx for any help.
<script type="text/javascript" > function display_elements() { var departments = new Array;
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.
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...
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 need to get the values of two hidden fields and values that make a query in my database and return this column to a text field in the same form, I have already informed the forum here that can do that with Ajax, researched and made an example But it is not working.
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.
