Combo Box In An HTML Form ?
Nov 27, 2009
I have a form which takes some values as input and stores them in a db for another use. I have the following java script to validate the entries.
Now I am planning to add a combo box to the form where I have the environment field. Following is the code for the form.
How to implement a combo box( ie first two options are US and UK and third one is a text box which i can enter any value, can't be left blank while submitting the form) with "Environment" field?

An existing JSP is generating the HTML page and table. I have retro-fitted it so that it adds to each input field a 'trigger' to the onkeyup event.
The purpose of this trigger is check for the the cursor keys being pressed (UP, DOWN, LEFT, RIGHT) and then if it is a logically valid move, shift to the next cell in that direction.
Now, the function it calls, doOnKeyUp, for the most part is working fine... when the input field in the table cells are a textbox or textarea, my method can re-focus the fields appropriately.
HOWEVER, I am having a huge headache when the input field is a combo box. Basically, the value of the combo box is changed with the cursor keys (which is default combo box behaviour (I think)), instead of moving to the next editable cell in that chosen direction.
Problem #1: My question: Is there a way to intercept/override the various onKey events or similar for the combo boxes. For the combo boxes, I want to continue to move between table cells UNLESS a do something specific, like press the spacebar to entire an update/modification mode for the current cell. Everything I have done so far does not prevent the combo box events from triggering.
Problem #2: Also, I tried a nasty hack to try and get it to work, by trying to switch the combo box's value back 1 spot (if it appeared to be needed) by changing the <combo box>.selected value. However, that change never appears to be taking hold, so it is staying at whatever the original selected value was. For this one, I am just curious as to the correct way to have javascript change the selected value in a combo box and make it "stick" and make it applied to the view/UI?
Code example:
You can probably tell by the code that I had been trying various things to change the combo box's selection via javascript, but none has worked for me.

What I have got is a form that a user has to fill out and submit (when validated all variables are stored in a session and emailed after multiple forms are completed), currently I have radio buttons, text boxes and a combo box/ drop down list (for location). All parts are working fine and validating fine. My problem is to do with the combo box//ddl. I have successfully validated the ddl so the user must select a location onsubmit and it is added to session and passed fine.At the moment the ddl only has cities or towns in it however as I would like to include different states and possibly different countries I need a code that validates the state first and then only gives the cities/towns that are in that state (otherwise my ddl would be to large). I can do this with links however I can't seem to do it in a form.

Here's the code:
[CODE]
<p><select name="FACILITY" size="1" onChange="redirect(this.options.selectedIndex)">
<option>Bretheren Village</option>
[code]....
the error message comes up put once you click ok you can still submitt the text even if its forbidden.... any way around this, such as deleting the text within the textbox when the error box is shown?

my issue is both a php and a javascript (AJAX) one its one or the other. I have two combo boxes one dependant on the other, populated by AJAX but when I submit the form the secondary combo is not being registered as a php $_POST['var'] in the following action page. The secondary combo is contained and altered using divs and inner.HTML. Is this an expected behaviour or is my issue else where?

I am using javascript to populate a number of text boxes based on the data item selected in the 1st combo box.
I am now working on making the selection of that combo box populate another combo box with items from another table. I can hard the sql code for the 2nd combo box so that when I select an option it populates more text boxes, but want the contents of the 2nd combo box to dynamically change depending on the selection of the 1st box. I would like this to do it without refreshing the page after each 1st combo box selection.
The 2nd box does not populate with the below code as I guess the variable isn't populated, I can put '1' in and it selects products with that prodid, but as explained above i'd like it to read the prodid from the 1st combo box.
Code:
<?php
require "session_logincheck.php";
function selectProductAndPopulate()
{
[Code].....

Regarding 2 combo boxes dependent with each other. Like the STATE AND CITY, when you select a STATE then depending on the state you selected ONLY CITIES under that will be populated on the 2nd combo box.

I have a search page where i have like 10 combo boxes and some radio buttons and check boxes.
Now when the page loads, i do some selection in the combo boxes and when i press reset button it clears all data in the form elements.
But when i select things in combo boxes and do a search by clicking OK button then the search results are displayed there and now if i want to clear all the form elements , i tried to click reset button, but when ever i did a search ie click ok button and after than press reset button reset button is not clearing the form elements.
Reason for this problem: Reset button resets the form to it's state when it was loaded (as opposed to clearing the values) so if the page loaded with the search values in it, when you hit Reset nothing will happen if you haven't changed anything. Code:

how I would go about changing the below to look at an SQL table
<script type="text/javascript">
var regiondb = new Object()
regiondb["2"] = [{value:"1", text:"Site1"},
{value:"2", text:"Site2"},
[Code].....

In my page there are a combo-box and a check-box that should have the following behaviour: When check-box is checked, the combo-box has to take a precise value and has to be not editable by the user. I cannot use DISABLED option because the back-end needs the value in the combo and READONLY option is useless with a combo-box.... So I don't know what to use to make the combo "disabled"

How do i select an option in a combo box? i have tried looking on the internet but dont really know what i should be searching for. what i want to happen is that when a function is called
a line of code will select a specific option in a combo box. something like:
//excuse the dodgy syntax
function select_combo() {
cb_1.select[3] //where option 3 will be selected (or 4 if first index
is 0)
}
the combo box would be something like:
<select>
<option>First</option>
<option>Second</option>
<option>Third</option>
</select>
The function would change the selection in the combo box.

I have to write a web page wht three combo boxes, all three are to be
populated from a database. - there tables = Bulidings, Floors and Offices
The user will choose a 'Building' from the first combo, once it has been
selected, I need to populate the second combo box with the 'floors' of that
selected building. The user will then select the floor, which in turn will
then populate the office combo box for the user to select.

I have 2 combo boxes where you can move the items in combo box 1 to combo box 2. I want to validate that combo box 2 actually has something moved to it. How can I count the items in combo box 2. Combo box 2 will initially have no items in the box on page load. It is up to the user to move the items to combo box 2 and I want to make sure at least 1 item was moved.
