Retrieving Form Values In Javascript
Sep 29, 2006
I am trying to create a form for authorised users to upload photos to
an image gallery. I'm attempting to perform simple validation of the
fields by ensuring the fields aren't empty and that the extensions are
right. However, I can't seem to access the actual values of the fields
to start with.
If I simplify my problem, can anyone tell me why this would work in a
Javascript alert:
alert(document.form.Photo1.value);
//This outputs 'D:/images/x.jpg'
but this won't:
var photonumber = "Photo" + 1;
alert(document.form.photonumber.value);
// I get "undefined"
The reason I'm doing this is because I'm looping through a finite set
of images and need to check each one is valid.
Is it because I'm not initialising the "photonumber" string correctly?

I have a form with a lot's of number of Text and Hidden Fields. I just do a simple loop to get each value for each attribute. I have about more than 2000.
if i do something simple like :
for (var i=0; i<2000; i++)
aValue = i+10;
it runs well. But if i do something like
for (var i=0; i<2000; i++)
aValue = document.myForm.elements[i].value;
it gives me 100% CPU for a long time before i submit the form.

So I'm a novice coder and have been trying to piece together a (seemingly) simple function. I want the user to be able to enter in a certain amount of time into a form, and then when they click submit, it opens a new page and closes after that amount of time.There is a very simple form on the first page that accepts input and looks like so:
<form action="onbreak.php" target="_blank" method="POST"><p class="fillable">I would like to view <input type="text" name="url" id="url" value="" size="30"/> for <input type="text" name="timeinput" id="timeinput" value="" size="3"/> minute(s). <input type="submit" value="Break Me!"/></p></form>

I'm trying to figure out what I'm doing wrong here. I have a select control and I'm trying to determine what index or value was selected and I can't seem to get it to work right. I'm sure it's something simple but I'm new at this.

I am trying to create a script to randomly assign recipients to givers for a Secret Santa.he participants are placed into groups. A giver cannot be assigned a recipient with whom he is grouped. I want to return all of the assignments in a table. I have made the following script. When I run it, it seems to get stuck in a loop. Any ideas why this might be? If you have any questions about how I want this thing to run, feel free to ask.

I am using the SVG plugin. I have a simple test and I am unable to retrieve the x and y values of a text object.
$('#objID1', svg.root()).attr('x')
This returns as empty. Where as:
$('#objID1', svg.root()).attr('fill')
successfully returns the fill value.
HTML code:

I have a form that has been dynamically created from PHP. It is basically a calculator and the number of form elements as well as names of the elements can vary greatly.
I basically want to add a button that will open a new browser window with the form info being passed to it. Basically it will create a quotation for the customer that is suitable for printing.
The only way I know to do the popup window is with javascript (unless php can do it). I know how to access form elements with javascript if the form element exists, but given most of the elements may change, I do not know how to access them.

I have:
1 form on the page. (no name, no id value set.)
3 hidden form elements named: catalog, vwoidc, oid
!!! I can only include the javascript right after the body tag. The
form is found near the end of the loaded page.
<form action="actionURL" method=post>
<input type=hidden name=catalog value=store>
<input type=hidden name=vwoidc value=69a6e1deb02417250691>
<input type=hidden name=oid value=60323></form>
Everything I've tried needs to have the javascript executed after the
page has been fully loaded.

Is their a way of iterating thru each tag within a form and returning the
value given in the id property, by that I mean the below html would return
the values idBoxOne, idBoxTwo, idBoxThree from the FormXX form.
<form name="FormXX" method="post" action="default.htm">
<input id="idBoxOne" name="bxOne" type="text">
<input id="idBoxTwo" name="bxTwo" type="text">
<input id="idBoxThree" name="bxThree" type="text">
</form>
Up to this point I've only used JavaScript to change CSS properties,
innerHTML and outerHTML so I'm rather new to the game.

Is there a way to retrieve the DOM element number in a form? For instance if I had 5 checkboxes with the same name and an event was fired to gather data, could I determine the DOM element number for each checkbox checked? I know this may seem like meaningless information, but I need it to do some other work on the page.

So, I have a form that, when the user clicks on a link, uses J/S to generate extra form fields for extra information. I can retrieve the value of the dynamically generated fields using $_POST in I.E., but it doesn't work in Firefox (no value is returned). Retrieving values for the static fields is fine in both I.E. and Firefox.
Here's the code - is there a function I'm using that could be replaced with something more friendly to Firefox?:
<script type='text/javascript'>
var i = 1;
function addArea() {
var newArea = addElement();
[Code].....

I have a form that gets values that a user has selected from a list menu field, that end up like this added to the URL:[url]
Instead of the Field being mentioned more than once, how can I have it where it could mention the field once with the values coma separated eg:[url]
Would I use JS to change the URL? or VBscript?

I have 4 text boxes that are supposed to load 4 seperate values of data from one field in one table from a database. The field is called interface_cropsettings (from the interface table) and these values have been concatenated and comma seperated in this field.
Code:
Once the form is filled out and saved, the data is inserted into the database and the values from these 4 text boxes are concatenated, comma seperated and inserted into that one field correctly.
(Example)
If the 4 text boxes have the following values:
In the database field they become:
However, if the form is closed and then re-opened, each text box displays the entire database field rather then each value seperated in the corresponding text box.
(Example)
All 4 text boxes display this:
I already know why the data appears like this in the form, my problem is that I'm not sure how to write the javascript to seperate the values into the correct corresponding fields, assuming javascript is what I should be using!
Also, this is kind of irrelevant but just in case you're wondering, this form is part of a cold fusion application!
