Onchange With Select Tag - Dropdown Box

Aug 26, 2011

I am using the OnChange event with the drop down box populated with countries.....but only works when certain countries are chosen.

When a country is chosen the OnChange event fires, passing a variable to the same page using the location.href.

Once this is done the onload within the body tag calls the function SetFocus() to the First Name text box.....which does not always work either.

Here is the code:

Onchange And Onkeypress Event On A Select Dropdown

Onchange To Fill Second Dropdown List Doesn't Work?

Apr 16, 2009

I have 2 dropdown lists which are connected to a mysql database. When I select an item from the first dropdown list the second dropdown list should show item which are linked to the item from the first list. But the thing is I can select an item from the first one, but the second isn't showing anything.

In the mysql database I have 2 tables: hesk_programma and hesk_projecten. In table hesk_programma there are a ProgrammaID and Programma column. In table hesk_projecten there are a ProgrammaID, a ProjectNumber and a Project column.

ProgrammaID from the two tables are connected to each other, so when I select an item from the first dropdown list with the ProgrammaID AK, the second dropdownlist should only display the items with the ProgammaID AK from the hesk_projecten.

Here is the code I use:

PHP Code:

<?php 
mysql_connect("localhost", "root", "");
mysql_select_db("bestellingen");
$query = "SELECT * FROM hesk_programma ";

[Code]....

By the way, one more thing. The ProjectNumber from the hesk_projecten table should be displayed (when selecting an item in the second dropdownlist) in a input text field.

Dropdown Submenu - Make A Horizontal Drop Down Menu With A Sub Menu ?

Nov 3, 2009

I actually want to make a horizontal drop down menu with a sub menu.As far as I have researched, I think that it can be done by JavaScript. I have searched for some java scripts but they are very long and complex.

That made me wonder that for a funcitonality like a Drop down is so complex?

So here is my question : Is there any JavaScript that can be applied for drop down menu exclusively? Which just presents logic of drop down solely?

OnChange Event - Populate Dropdown Fields Separately From Database

Dec 17, 2011

I have two drop-down fields that are populated separately from the database. Here is my HTML/PHP code
Drop-down field #1
<tr class=bodyTRstyle>
<td width="35%"><p align="left">Venue</td>
<td class=fieldTDstyle width="269"><p align="left">
<select name="VenueName" class=VenueName><option selected><?php echo $VenueName?></option

<?php
$SelectVenueQuery="select * from venue order by VenueName";
$SelectVenueResult=mysql_query($SelectVenueQuery);
while ($VenueRow=mysql_fetch_array($SelectVenueResult)){
extract($VenueRow);
echo "<option value='$VenueName'>$VenueName";}?>
</select></td></tr>

Drop-down Field #2
<tr class=bodyTRstyle>
<td width="35%"><p align="left">Results</td>
<td class=fieldTDstyle width="269"><p align="left">
<select name="GameResults" class=GameResults><option selected>
<?php echo $GameResults?></option
<?php
$ResultsQuery="select * from result order by ResultDate";
$ResultsQueryResult=mysql_query($ResultsQuery);

While ($ResultsRow=mysql_fetch_array($ResultsQueryResult)){
extract($ResultsRow);
echo "<option value='$ResultDate'>$ResultDate";}?>
</select></td></tr>

This code works well as long as the two drop-downs are independent of each other. The result table has VenueName as an element, so each venue has a set of result records in the result table. This is how I want to change it: The Venue dropdown will remain as it is. Once the Venue Name is selected I want the result dropdown to populate with ONLY the result records containing a match on VenueName that was selected in the venue dropdown. How do I do that? Is it with a onChange Event? What are the changes that need to be made? How do I communicate to the second drop-down what was selected in the Venue drop-down??

Pass The Value Of Dropdown To A Function And Enable Another Dropdown

Mar 7, 2010

I have 4 strands of hair left... I have been fighting with this one for almost a week now. I'm trying to pass the value of this dropdown to a function and enable another dropdown(and in the future create the populated dropdown based on this choice). If the original 'Select...' option is chosen it will then hide that second dropdown. In the following code the function actually resides in a js file which has been imported and is working properly. I have tried this as text and as value and both seem to be passing a null value regardless of the option selected.
