Changing Variable Value Based On <option> Selection

Aug 20, 2011

I need to change the value of a variable on a <select> question.

Code:

Currently the variable choses either 1or 2 so when I execute the function it will sum the value ie..3,6 ect.

I would like it to add the value in the text part of the option ie.. 5000,10000,15000.

I realize if I could I could change the value to be the same as the text value but the backend of this software needs the values to stay 1 or 2.

I was trying to do an "if else" statement but I am not sure how to format the syntax to work:

Code:

Changing Hidden Field Value Based On Selected Option

Aug 25, 2009

how to Change a Hidden Fields Name based on selected option. The hidden fields name is sent off and I need to change the name depending on what option they select. For if they select MyList the hidden field name needs to be SelectLists[40] or if they select testlist the hidden field name needs to be SelectLists[41]. This is probably way, way off but I've done this and it doesn't work.

JQuery :: Removing An Option From A Select Based On The Option Value?

Jun 21, 2010

I'm using the following code to remove an option from a select control based on a selection in a different select control and the option text in the select option that is being removed. The code works as I want it to, but I would prefer to use the option value for identifying the option to remove instead of using the option text. I've tried several different ways to do this, but can not find the proper syntax.

Form Submission On Option Selection

Dec 2, 2010

I want to use a drop-down menu selection option to submit a form. But the form's contents change depending on the option. This is the basic form:
<FORM ID="go1" METHOD="POST" TARGET="_self">
<INPUT TYPE=HIDDEN NAME=UserID VALUE="<%UserID%>">
<INPUT TYPE=HIDDEN NAME=Password VALUE="<%Password%>">
<INPUT TYPE=HIDDEN NAME=SubUnitID VALUE="4266">
<INPUT TYPE=HIDDEN NAME=PageID VALUE="1">
<INPUT TYPE="IMAGE" class="hand" border="0" src="/images/my.gif" width="45" height="26" vspace="5">
</FORM>

At the moment, it's an image which gets clicked on but it needs to be the option chosen. I think I can do that with:
function gotoPage(s){
var v = s.selectedIndex;
var select = document.forms.form.elements.input; // selects question
if (v == 1){...}
if (v == 2){...} etc.

However, as I said, the form's contents must change depending on the option chosen: The form's values which change are:
<INPUT TYPE=HIDDEN NAME=SubUnitID VALUE="4266">
<INPUT TYPE=HIDDEN NAME=PageID VALUE="1">

Div To Appear Based On Dropdown Selection?

Aug 2, 2011

Code:
<div id="1">
<asp:DropDownList ID="DD1" runat="server">
<asp:ListItem>option1</asp:ListItem>
<asp:ListItem>option2</asp:ListItem>

[Code]....

I want the div with the id of "option2show" to be hidden unless the user has selected option 2 in the dropdown box.

If the user has selected option 1 then nothing will happen, however iff option 2 has been selected then the option2 div will appeaar. I would like this to happen before any submit buttons are press, so i guess onblur of the dropdown box.

Changing The Url Of An Iframe With A Selection Box

Mar 29, 2006

I have been wrestling with a problem, I am trying to change the url of
an Iframe from a simple selection box, once the user selects the
desired url they wish to visit from the main page the iframe then loads
the url while not affecting the main page. I am using the onchange
event of the select tag to drive the javascript function hopefully
passing the value of the selection wich in this case is the url to the
independant script wich will in turn will change the src of the iframe
from the default page that is loaded when first viewing the page.One
question I have is would it be better to use the onload event to set
the initial src then use the onchange event form the select to change
the src or staticly set the src then use the onchange event to change
it? below is an example of my code so far. Also currently whenever I
try to pass teh value to the script I get an object expected error and
nothing happens.Bear in mind I know enough C++ to make myself dangerous
and can stay on top javascript to a point but right now I am just lost.
just need a nudge in the right direction at this point please :D

<select name="sites" id="sites" onchange="changesite()">
<option value=" "> </option>
<option value="http://www.nanpa.org">NANPA.org</option>
<option value="http://www.google.com">Google.com</option>
<option
value="http://www.spywarewarrior.com">spywarewarrior.com</option>
</select>

Function changesite(value)
{
var newsite = value;
document.frames['websites'].src = newsite;

Hiding Dropdown Menus Based On Selection

Sep 8, 2010

i am building a website form which I would like the user to select a product of interest. Some products are three tiered and some are two tiered.

1. Example of three tier (3 dropdowns required only):Scooters (dropdown 1)Three Wheel Scooters (dropdown 2)
Delux 503S Bird Scooter (dropdown 3)

2. Example of two tier (2 dropdowns required only):Standing Bikes (dropdown 1)Children 300 Series (dropdown 2)

If the user wants to submit their interest for one of the products, I need to have at most 3 dropdown menus. So in Example 1, I would have 3 dropdowns in my form. Dropdown 1: Scooters Dropdown 2: Three Wheel Scooters Dropdown 3: Delux 503S Bird Scooter.In Example 2, I would only need to use the first 2 dropdown menus. (Obviously the first dropdown would contain 'Scooters' and 'Standing Bikes' in the menu list)I would like to alter the code so that the second and third dropdowns are hidden until a selection from the first drop down is made. Once for example, 'Standing Bikes' is selected from the first dropdown menu, the second dropdown menu appears and the third remains hidden due to the fact that it is not required. If I selected Scooters from the first dropdown menu, the second dropdown would appear listing all items associated with this and at this point the third dropdown menu is hidden. If i select 'Three Wheel Scooter' from the second dropdown the third dropdown menu now appears listing all Three wheel Scooters such as 'Delux 503S Bird Scooter'.

Hiding And Displaying Forms Based On Selection

Dec 30, 2010

I am trying to display three different types of forms of the same page. One of the three will appear based on the selection. Right now my code has everything shown when you first reload the page and then when you select something it all disappears and nothing comes back. I am trying to use divs because the forms will perform the same action just with different parameters. It is a lot of code but the forms are the same thing just wrapped in a different div and I know they work. hopefully this will cut down on the amount of time you have to look at it.

Below is what I have so far:
Code:
<html>
<head>
<script type="text/javascript" language="javascript">
function choose()
{
document.getElementById('notes').style.display = 'none';
document.getElementById('tests').style.display = 'none';
document.getElementById('homework').style.display = 'none'; .....

Disable Options In One Menu Based On Selection In Another

Feb 22, 2011

I am new to javascript stuff but am looking to develop a form which includes 2 drop down menus but I would like to grey out some options in the second one based on the selection in the first. Basically this is a simplification of what I have:

<select name="orientation" id="orientation">
<option value="OR1">South</option>
<option value="OR2">East</option>
<option value="OR3">North</option>
<option value="OR4">West</option>
</select>

<select name="location" id="location">
<option value="L1">Front Left</option>
<option value="L2">Front Right</option>
<option value="L3">Rear Left</option>
<option value="L4">Rear Right</option>
</select>

What I would like is that if south or east are selected for orientation then I can only select front left or front right but if north or west are selected then only rear left or rear right are available.
