Forms (onChange?)
Oct 11, 2005
I'm making a form and I need it to do this:
From a drop-down box, the user chooses their country.
- User selects a country other than Australia, nothing happens.
- User selects Australia, another drop-down box appears with Australian states
* If they select a state other than Victoria, nothing happens
* If they select Victoria, another drop-down box appears with Region
I'd like the subsequent drop-down boxes to be either inactive and unclickable (technical terms here ) or not visible at all until the above conditions happen.

how to add forms in javascript, but it's limited to text input forms.
<script type="text/javascript"><!--
function updatesum() {
document.form.sum.value = (document.form.sum1.value -0) + (document.form.sum2.value -0);
}
//--></script>
Where the inputs sum1 and sum2 are text fields you put whatever numbers you want in. That works fine. Great. Now what I'm having trouble with is modifying the code so that it will add one form with an input number with a form that spits out a randomly generated number.
<input type="button" value="D20" onclick="this.form.display.value = Math.round (20 * Math.random())" class="buttonHi" /> <input name="display" type="text" size="6" value="" />
This is what I'm using for my random number generator. So basically I want to be able to put, say, 5, into the input text field above this. And then click on the d20 button to get a random number, say, 15, and then have the first code add the inputted 5 with the randomly generated 15.

Is there something that will update as soon as the user changes information in a textbox as appose to what onChange does, which is update once the focus has been taken off of the textbox? I am writing a custom cart and I am using AJAX to update the price according to how many they are ordering, I was hoping to have it update the price as soon as the user put in the volume, but it doesnt update until the user clicks somewhere else on the page.

Can I target the element and base an onChange outside of directly calling it in the element tag?
Due to the nature of my script, the best I can do is wrap a tag around the element.
example of what I am trying to do
Code:
<script>
document.form.field1.onchange = function();
<script>
And if this might work, can I call it in the head or must it come after the element.

Using DOM in IE, how can I loop through FORMs and access FORM elements
in a specific form? For example, www.hotmail.com has about 13 forms.
I believe the one displayed is dependent on the URL. If I want to
access the submit button of the visible form, which is usually the last
one, how is that done?
Currently, I look for type=submit using DOM but it doesn't find
anything and only loops through the first FORM elements.

I've been trying to teach myself JavaScript via a book and a number of
JavaScript Tutorials Online. I have more understanding of what I am doing,
although definetly not has much as what I have read on this newsgroup.
I'm trying to learn a new skill in order to hopefully get a job. My job went
to india while I was out on medical leave (carpal tunnel.)
My question, I have two JavaScript / Htm pages identical to the one below.
I'm trying to figure out how I could put both of these "identical"
javascript pages into One HTM page. But I am clueless as to what to look
for and or how to proceed. I'm thinking that I need to somehow add a
checkbox_checker() and a checkbox_checker(2) or something like this.
I've looked at the "For Dummies" book on JavaScript, and my Beginning
JavaScript Book as well as Google'd. Funny thing is though you have to have
enough "knowledge" of JavaScript to know what to look for....

If I have a form as below:
<form name="Show" style="position:absolute;top:200;left:450;background-
color: yellow">
Mouse location.<br>
X: <input type="text" name="MouseX" value="0" size="4"><br>
</form>
Then accessing the value of the text box is simple:
alert(document.Show.MouseX.value)
But what if I use a div instead, how can I get at the same value?
<div id="Show" style="position:absolute;top:200;left:450;background-
color: yellow">
Mouse location.<br>
X: <input type="text" name="MouseX" value="0" size="4"><br>
</div>

i have two forms(form1 and form2) on my html page.
question1 : can i access form 1 variables in form 2?. if so how?
question 2: when form2 action is saveci.jsp . can i access form1
variables in saveci.jsp. if so how?.
basically when form2 is submitted, form1 variables should be accessed
in the jsp which processes form2.

i'm trying to use javascript to change the content of a textbox in a
different frame.
by clicking on a 'folder' link in 'leftFrame' i want to put the value
assigned by that link into the 'folderName' textbox in the
'uploadForm' form in 'mainFrame'. i'm doing this as...
onClick="parent.mainFrame.uploadForm.folderName.value='fold er'"
this works perfectly fine with IE and Safari on my Mac OS X machine
and IE 6 on my PC laptop but anything Mozilla-based on either machine
gives me an error i just can't seem to get round...
'parent.mainFrame.uploadForm has no properties'

I'm trying to add an input element to all forms using appendChild.
The script first searches for input elements with the name of "myinput".
If it finds an input element with that name, it assigns the value "myvalue".
If it can't find an input element with that name, it tries to create a new one for all forms.
Code:
What's wrong with my code?

I'm not a JS person, so hopefully this'll be nice an easy .
The follwoing bit of code:
Code:
<script language="javascript">
// if form exists , set cursor in first input field
function focusonform()
{
if (document.forms[0]) {
document.forms[0].elements[0].focus();
}
else
{window.focus();}
}
</script>
This appears to work fine on a page with no forms using Mozilla 1.0, IE6 on win2000. But NOT on IE6 on XP - I get the following message:
A Runtime Error has occured.
Do you wish to Debug?
Line: 70
Error: 'document.forms.0.elements.0'

I am trying to create a form (a quiz to be exact) and I know how to create one in php. The only problem with this is that the location that I am planning on installing the quiz does not allow me php access, a cgi-bin or even internet access . Iam able to use html pages from a location stored on the desktop or in a network folder.
My idea is to have the first page be the actual quiz with the users selecting the answers. The following page (whether its a popup, text file, or a new page) would be where the answers are displayed and then ultimately printed to paper. Most of the scripts that I have found that would do something similar are email style scripts (I am unable to use this method)
This is what I have in php and is the type of format I am looking for in javascript. (I'm not very proficient in php as I just started and I have no clue about javascript) Code:

I'm embarking on a rather interesting wine cellaring project where I need to enable a user to add form fields (a complete table row with several fields) on demand.
If they start filling out the form and need another row for another bottle, I need them to be able to click a button that adds a new row to the table with the same fields.
I also need perhaps another button that will create the row and duplicate the form field values of that row. The winery, wine namen and variety may be the same but the year may change and I dont wan thte user to have to do any double entry. I've been researching DOM and have been looking at sites like Quirksmode.
Am I heading in the right direction? I'm just about to go an buy a book on DOM and start really getting into it.

I need someone to point me to the write direction here. I know nothing of javascript, and I've tried looking everywhere I can on Google.
I have a drop down of all the sizes I have in a database. I call them to a form with the ID number as the value. What I want is when a user selects a size, it gets added to the table. For example:
<table>
<tr>
<td>Paper</td><td>size</td><td>quantity</td>
</tr>
<!--Repeat this bit with javascript according to the Paper/size chosen on the drop down -->
<tr>
<td>Glossy</td><td>4x6</td><td><input quantity form></td>
</tr>
<!--End repeat here -->
</table>
