Dynamic Form Field Generation From <select>?
Mar 21, 2005
I have a form with a number of <select> fields, some of which require additional fields to be displayed/enabled depending on which <option> is chosen. For example, in the following code, I'd like a <textarea> field to be displayed if users choose the 'Other' option:
<label for="venue_type"><p>What type of venue do you require?</p></label>
<select name="venue_type" id="venue_type">
<option value="null">--Please choose--</option>
<option value="Meeting/Training/Seminar room">Meeting / training / seminar room</option>
<option value="Computer Suite">Computer Suite</option>
<option value="Examination room">Examination room</option>
<option value="Lecture theatre / auditorium">Lecture theatre / auditorium</option>
<option value="Other">Other type of venue</option>
</select>
I'm guessing that it's possible to do this using onchange, but am not too great with Javascript .

What I'm trying to do here is to create an editing form based upon the field descriptions extracted from a database, and use jQuery (e.g., datepicker) to handle the input. So, using the datepicker example, I create an input item, make it a 'text' type, give it a name and an id, and then use $('#'+textfld.id).datepicker({ ... }) to set it up. This is NOT done at $document.ready time, but while running the form's JavaScript, so I don't know if that's the problem or not; I can't see how to use $document.ready here due to the dynamic nature of each field.
AFAICT, what should happen here is that a jQuery datepicker should be created and associated with the text field - but nothing at all is happening.

I'd like some help trying to generate input fields on the fly. What I
have on an HTML page is a single text input field labelled #1, e.g. #1
<input type="text">. Next to the field is a button that, on click, I'd
like to automatically generate a second text input field below the
first, labelled #2. Everytime the button is clicked, another field is
created with an incremented label.
I explored iframes, but these text fields will be part of a larger
form that has to be passed together. I'd rather not use hidden text
fields because I don't want to hardcode a limit to the number of
fields available. Please point me in the right direction, or let me
know if this isn't possible.

I am using ASP to dynamically generate a series of forms. When the
page is loaded, everything appears to be correct, except that the
first form generated fails with a "FormName is Null or not an Object"
error. Each subsuquent form created by the code after that works
perfectly. Why is it that the first form, generated with exactly the
same block of code, fails? Code:

I have to do a project, the requirements i have got are, same link on multiple pages should lead to a single page on client's site, but the page should be different for each link clicked.
What i understand from this is, we will send parameters with each link to a JS or php file and then generate a dynamic page each time, but i am not clear how many files we need to call and what will be the sequence. I want to implement this in JS and php.
how to implement it with JS and PHP if we send parameters with the url and if we don't send any parameters.

I've been working on a redesign of our site at ExperiencePlus for some time now, and long ago chose CBE menu 9 over the other menu technologies out there because of its browser independance. Problem is, as you can see, we have a pretty large site; load-times for the menus and associated scripts are approaching prohibitive. So I'm trying to speed things up.
You can see the results of some simplification here - still about the same speed by my guesstimates.
So, my question is twofold, I guess. First, Mike, do you have any ideas about how long it will take X menu 4 to reach maturity? No pressure ;^) If it were ready now, I'd just drop CBE in favor of X.
Second question: How much performance improvement can I expect from removing unnecessary code (sliding, for example) from the CBE core files? I haven't played with that stuff at all, except to read it now & then when looking for solutions to problems. Does anyone have a similarly large implementation of CBE menu9 that runs faster, so that perhaps they could share their experience?
One final thing: I'm planning to eventually shove all this into a PHP document that will auto-generate chunks of the menu from database queries, especially around the tour & country listings and our "Resource Room." (X menu 4 looks like it would be vastly superior for that purpose, since it's so lean.) I'm interested in hearing from anybody who's tried to do something like this, whether they succeeded or not.

There's a feature I want to implement, but don't really know how to code. The intention is to use jQuery to convert words with a certain class attribute into Wikipedia links.
An example to make things clearer:
PLAIN TEXT: There is a <span class="wiki">penguin</span> there.
EXPECTED RESULT: There is a <a href [url] there.
Hence the code would have to grab the string of words inside the tag and place them inside a href with the first part of the link already attached to it. Doesn't seem too complicated, but I wasn't able to do it.
I have been trying to use the code below (created by Patrick Haney and improved by enraged) as a basis, but no deal. This code subistitutes words for code, but it searches for specific words.
If anybody knows a script like that, modify the code below,

I have a form that allows for dynamic field creation. Basically, you click the + button, and an addition row of fields (2 text fields) are created. The area that is dynamically created is wrapped by a <div id>, within which is, and this might be bad practice so please feel free to mock me , another few nested div id's. It looks something like this:
Code:
Each time you hit the +, it creates a new div id beneath the "Adds" id.
What I'd like to do is see the values of the id's "row_fqdn" and "row_ip". Is there a quick way to access the values of nested id's?
I found a workaround but it seems pretty messy and drawn out, something like this:
Code:
I'm looking for a way to do something like this:
Code:
But that doesn't work.

A while back, I an working on dynamic form creation. I wanted a user to be able to enter into a text field how many designs he or she would like, then, based on that number, be provided with a pair of text boxes that asked 1) name of design 2) quantity of that particular design. I received this cool way of doing it by user thraddash:
<head>
<script type="text/javascript">
function BuildFormFields($amount){
var
$container = document.getElementById('FormFields'),
$item, $field, $i;
$container.innerHTML = '';
for ($i = 0; $i < $amount; $i++) {
$item = document.createElement('div');
$item.style.margin = '3px';
$field = document.createElement('span');
$field.innerHTML = 'Name of Design';
$field.style.marginRight = '10px';
$item.appendChild($field); .....
As a followup, I wonder how to control in a table where each of these text boxes will appear.

I have a form with a field that asks for a full year. If the year is greater than 20 years ago, I'd like additional form fields to be revealed. If the year is equal to or less than 20 years ago, it will not reveal the fields. (And it should be based on getFullYear(), so I don't have to update the script every year, yeah?)
I figured out how to script onclick functions and some basic .value == functions in order to show/hide just about every type of form field. So I don't need that info. But I'm unsure of how to calculate the value.

I have a form with a dropdown and input field:
<form1>
<select name="warranty" id="warranty" onChange="doadate()">
<option value="Select">Select</option>
<option value="In Warranty">In Warranty</option>

But it's not working, it stays disabled after load even when the DOA is selected in the dropdown form field.

I have a form where a user may select a box from above which will query the database and autofill in the fields. This works properly for all of my input text fields but I have a select box where a user selects their state that I am unable to get to properly populate.
The select box is populated on page load in the following format....
<select id="state" name="state">
<option value="1">ALABAMA</option>
<option value="2">ALASKA</option>
</select>
[Code]....
Everything populates correctly except where I try to set the val on the state select field. It does not change at all. I need it to display the statename with the value of the state (number).

I have a form with two select fields (facility[] and lightbox[]), along with a few other text inputs. Both of the select fields allow the user to select multiple options. This is fine for our needs, as long as the user only selects fields from within one select box. As soon as the user decides to make a selection from the other select field, I'd like to permit that, but clear all other selections from the first field.

I am developing a small app in Joomla! where I need to sequentially number file folders. On the page where I add new folders I have a select menu to select the type of folder. In this case, either Action, Reference, or Archive. What I want to have happen is after I select the type of folder, I want to enter the next available number in the form field. I realize to do this without resubmitting the page I need to use javascript and onchange. The problem is I am almost clueless when it comes to javascript (I am working on it though) so I need some help. This is what I have.
Code:
<fieldset class="adminform">
<legend><?php echo JText::_( 'Folders' ); ?></legend>
<table class="admintable">
[code]...
I assume I have to pass my php array into a javascript array then call that based on my select menu. Only I have no clue how to go about doing that.

I'm trying to create a dynamic menu where a user selects one item and another select list is shown, then another and another (and so on). Here is my JS, it *should* be taking the ID of the div, comparing it to the selected value and then showing another div by settings it's class property to visible:
