Inconsistency Btw Form.element And DOM
Jan 30, 2004
I used DOM to add another input field ot the middle of a HTML form, when I do a submit or look at the fields using form.elements, they are in the right position in IE.
However, if I do it in Mozilla, the new input field shows up at the end rather in the right position. For me, the ordering in submit is important. Is there anyway to get around the problem?
BTW, using DOM to go through the fields is a pain too because one cannot just use getElementsByTagName('INPUT') because there are also textarea and select.

I'm having some problems understanding the append() function. What I'd like to do is select an element using it's ID and add a row to the table with a HTML form element. The table is dynamically generated using a Django template ( form.as_table() ) so I'm not able to alter the original HTML markup too much.
If I had a table like this...

I have created a form with malsup's Form Plugin wherein it submits on change of the inputs. I have set up my jQuery script to index drop down menus and visible inputs, and uses that index to determine whether keydown of tab should move focus to the next element or the first element, and likewise with shift+tab keydown. However, instead of moving focus to the first element from the last element on tab keydown like I would like it to, it moves focus to the second element. How can I change it to cycle focus to the actual first and last elements? Here is a live link to my form: [URL]. Here is my script:
$(document).ready(function() {
var options = {
target: '#c_main',
success: setFocus
[Code]....

How does one cause a form element to appear ONLY if a certain form selection is made before it?
That is for example say there is a form element of type Radio called "format" so only if they select format value = normal then the form input fields called URL and Name are to appear as the next choices otherwise form input field Group and checklist Places are to appear as the next choices.

I'm working on a script that will produce multiple dynamic forms based on the results of an ajax request. The ajax request does a db query that will return 0 to x number of rows. For each row, a new serialized form is created. Since the forms do not exist at page load, I'm having problems getting the value of the form elements so that I can run other functions on them (update inputs and selects). I've stripped down everything so that I can show a basic example. In the example, how would I get the value of "#orderID"? The body contains a div (previousList) that has a list of items that when clicked will trigger the ajax query. It also has a div (line details) that will hold all of the forms that are generated.
<div id="lineDetails">
check it out </div>
<div id="previousFrm" class="ui-widget-header ui-state-highlight ui-corner-all">
<h3>Previous Returns/Cancels</h3>
<div id="previousList">
<ul class="previous" id="returnList">
<li id="1000997" class="names">1000997: 101853</li>
<li id="1000995" class="names">1000995: 101853</li> .....
But callingconsole.log("order line value is " + $("#orderID").val());
results in 'undefined'.

I have a form in my webpage and i am referring to the form element as formname.elementname. But when i select 5000 records from one screen and goes to other screen the form in the new screen stops recognising its element. If i do not select 500 records from screen on and directly going to screen 2 the screen works perfectly fine. Any Known bug with i think.

I'm trying to make it so that if the user sets focus to a form element
(text), it automatically sets focus to the very next form element. This
will, in effect, prevent the user from modifying the value. I know I can do
this by setting the form element to 'readonly' but that's not possible as
I'll need to modify that value elsewhere in my JS. Anyway...
I know I can do something like this:
document.forms[1].elements[4].focus().
Only problem for me with the above method is that I'm generating my form
dynamically so I won't know a) which element number the current field is and
b) which, if any, is the next element. I've tried setting up an event
handler so:
but that doesn't work. Apparently, I can't use nextSibling when working
with a form element. So I'm wondering how I can do what I'm needing to do?

Is it possilble to get the name of a form by an element within it. Scenario: I have a page that has a menu system and on of the <a href> I have this
Code:
a href="javascript:formSubmit(this);" class="delete" onClick="javascript:setTextValue('request', 'delete');">Delete</a>
That then goes to this funcion (please forget the setTextValue) that works which just sets a hidden input to that value for processing later

How do I get the ordinal of a form element from a reference to the
object itself.
For example:
<html>
<script language="javascript">
function disp_val(objField){
alert(---the ordinal of objField in form---)
}
</script>
<body>
<form>
<input type="text" onblur="disp_val(this)"><br>
<input type="text" onblur="disp_val(this)">
</form>
</body>
</html>
I need to pass the ordinal to another function which I have no control
over. Not having any luck figuring this out. I'm sure it's simple and
I'm missing the obvious solution. I'm workign strictly with IE 5.5+.

Is it possible to use variables as the name for a form element e.g.
<script type="text/Javascript">
<html>
<head>
<script type="text/Javascript">
var myvar = 1;
</script>
</head>
<body>
<input name="myvar" type="radio" value="radiobutton" />test
</body>
</html>
I tested the above and looked at the course. The name is shown as "myvar" and not "1", so I guess it didn't work.

In a thread somewhere, someone wanted to know if there was a form element that would create a slider bar for the users to select a rating for something or other.
Well I went away and made one in DHTML and it works in all but five browsers (IE 3.0 4.0, NN 4.79 Opera 5.02 6.00) that I have tested it on.
Once I had made it, I decided to make it more customizable by allowing users to set the width of the bar more easily.
Then I considered using XML to create the slider bar so that it would work for non-JavaScript users, I decided against this for two reasons, not many people use XHTML for their pages and I don't know XML. Instead I just included a noscript section with just a normal text box in.
Then someone at school told me that I could use ActiveX to create a slider bar. Well, lets just say that I know more about XML than ActiveX and leave it at that.
So as it stands this is just your average, run-of-the-mill, DHTML script. I'm posting it here to see if anyone can think of any ways that I could make it better or just tell me how damn good it is. :D I don't mind either way, honest.
I plan on submitting it to Dynamic Drive so that's why there are credits all over the place if you're wondering.

I'm trying to determine a better method of finding the index value of a form element. I need to find it because the JavaScript validation class has a function for validating a single form element, but it requires that the index number of the element in the form be passed in.Currently I am accomplishing this by a function that I wrote which I call for each field I want to validate:
function getIndex(element)
{
for (var i=0; i<document.thisForm.elements.length; i++)

Here's my situation:
I want to loop through a set (10) of similar named form elements to check if they are blank:
for (i = 1; i <= 10; i++)
{
if (document.form1.firstname??.value=="")
{
alert("A FIRST NAME is required to proceed");
document.form1.firstname??.focus();return false
}
}
My question is how do I refer to the loop variable "i" in location "??"

Having a form like this:
HTML Code:
when I capture the dispatch of the form and try to get the value of any of these file fields:
PHP Code:
There's a Javascript error saying that form.file is undefined. It's strange because I see in Firebug that "file" actually exists as a property of "form". The same happens if I get rid of the temporary variable "form" and I do it this way:
So, I eventually had to use the getElementById('image' + i) method in order to do what I wanted. But there must be a "natural" way to get a value from an array defined in a form.

i have a menu generated by a list with nested lists. i want the parent link to stay highlighted when the mouse hovers over the sub menus. because those sub menus are also generated by jquery (qtip), CSS alone won't do it (triedul.topnav li:hover a {background-color: #F00;}).is there a way to do this using jquery?

Mozilla-based browsers have watch and unwatch methods to detect change
in value of form elements (or any Javascript variables really). IE
doesn't support this.
Is there a a reliable cross-browser way alternative to this? Something
that will let me detect a change in value for a form element and
trigger my own callback function upon change?
Hopefully, something that is generic enough to be called as
"MyWatch(element)"!

I have this form that depending on the shift you choose certain form elements get grayed out. Here's the part that I don't understand. I validate the form in php and display the errors but the form re-enables everything that was grayed out. Not the behavior I was expecting. How would I go about this?I attached a copy of the HTML source created from php.
