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

Jul 21, 2009

I have a select dropdown which has two events an onchange and onkeypress.
My problem now is when I use the keyboard arrows to select an item from the list in a select drop down the onchange is selected(invoked) before I even reach the second item in the list when using opera and IE but working fine with Firefox and chrome.The onblur event does not work either because the focus must be set to following tag

3 Level Dynamic MySQL Dropdown

Apr 12, 2010

I'm trying to make 3 drop downs (based off of mysql tables), to narrow down the selection. Source, School, and Program. So when when they select SOURCE(source), all the SCHOOLs in drop2 will be based on the SOURCE selected in the previous dropdown, and whatever school(cid) is selected, the program will be based off that school(cid) and display all the programs for that school. I've google'd high and low for something, and no avail. Here is what I have, I am just trying to make 3 drop downs narrow in, without pressing submit (I am new to ajax and javascript etc) The issue may be in that java part, I've look in the php and mysql, but nothing.

PHP Code:
<table width="517" border="1">†<tr>
<td width="87">Source:</td>†<td width="414">
<? echo'<select name="source" onChange="showUser(this.value)">
<option value="">--Select--</option><?php while() { } ?>'; .....

My javascript
Code:
var xmlhttp;
function showUser(str){
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null){
alert ("Browser does not support HTTP Request");
return;
} .....

Right now, the results display in a table, I don't want that - I need them to display as results in the next dropdown.

JQuery :: Selecting A Dropdown Item From MySQL?

Dec 30, 2011

This one should be easy. In fact, it was working for a long time as far as I know. Then I upgraded from jQuery 1.4.4 to 1.7.1 and a few things stopped working. (This is according to my client; it's possible it's been broken for a long time.)

So a customer logs in and sees his/her registration information. Name, address, phone number, etc... It gets this information from a MySQL database. For the customer's home address, there's a dropdown for the state (MA, NH, etc...) Rather than displaying the default specified in the HTML code, I have a bit of jQuery code that is supposed to change the dropdown selection to the user's home state as stored in the MySQL database.

Unfortunately, nothing happens. It rather than changing to the user's home state, it just displays the default state (AL, the first alphabetically).

[Code]..

I verified that $row['state'] contains valid data by outputting it as HTML on the page (my test data outputs "MA"). And I'm reasonably sure that this used to work in the past.

Mysql Dropdown Fill Input Fields In Php

Apr 7, 2009

I have a mysql database (name) which helds 3 fields, id, naam, email. In php I've made the connection and create a selection menu and with javascript I was able to display, (when I selected for example "Bas" in the selection menu), bas his name into a first input text field. Now a couple of things I still want but can't seem to get it right.

First: I also want to display "bas" his email address in a second input text field. (the database contains more names, but this an example).

Second: The selection menu starts with the first name in the database, but can I make it for example "Select name" as beginning.

Passing Current Value Of Fields To MYSQL Dropdown

Sep 27, 2010

i have a form with fields (30+), and about 5 of them are fields that need to pass into my dropdown (actually a dynmaic dropdown, select SOURCE, then whatever source u select it'll show options that are mysql source=$source), so it can go into my mysql query, and filter out the best results. (i.e date_of_birth, min_credits, state, etc). Needs to be done without submitting, hence javascript. Im echo'ing my query and its saying the variables i'm trying to pass are UNDEFINED. Am I not passing the vars correctly? do i need to prep the vars to "grab" them in the current field?

PHP Dropdown - Populate A Combobox With Data Pulled From A Mysql Db

Apr 11, 2011

I want to populate a combobox with data pulled from a mysql db . The value of second combobox depends on what's been selected in first combobox. I assume pulling the data completely when loading the combobox and then filtering it locally to populate the second combobox based on the selection in first combobox will suit my needs so that i do not have to query server.What is the best way of doing it?

Ajax :: Dropdown Menu Pulling Info From MYSQL Database?

Jun 20, 2009

I need to create three dropdown boxes (box 1:colour, box 2: price, box 3:brand) and when the user presses "GO" they are returned with the correct information, pulled from corresponding fields in my MYSQL database.

For example, colour: silver, price £100-£200, brand:samsung...should return 5 items on the page. I do not need the dropdown boxes to populate depending on ther previous selection - they are static, so to speak. If possible, I would like the information to be retuned to my page without the URL changing, which leads me to think I will need to be ausing ajax....?

SELECT OnChange Auto Fill Other SELECT Boxes

Jul 25, 2002

I searched here and some other places on the net but cant find anything that suits my needs. I have a SELECT box with 3 values Code:

<form name="form1">
<select name="length">
<option name="length" value="none">--Select for All--</option>
<option name="length" value="5">--5 Days--</option>
<option name="length" value="7">--7 Days--</option>
<option name="length" value="10">--10 Days--</option>
</select>
</form>

OnChange, I want to invoke a function that auto populates the rest of the SELECT fields in the form. The select boxes will vary in quantity as the page is dynamic, but the values are always the same (like the code above).

Does this make sense?

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.

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??

JQuery :: Select Dynamically An Option In A Dropdown Select?

Aug 11, 2010

According to [URL] intended way for jQuery to change dynamically the selected option of a dropdown select control isassigningthe desired text instead of the value. I found this way veryinconvenient (data structures usually deal with value codes, not value descriptions) and it seems to work only sometimes.

Trying different options I came out with this approach that seems to do the job so
far:

function setSelect(pID,pSelectedValue)
{
$('#'+pID + ' option:selected').removeAttr('selected');

I want in the select option a standard word, for example: select name.But when I add a line of option just after the first select (bold text), that line takes the first record of the database, but it should be a blank line (nothing linked to it, just a reminder to select a name).This is the code I have now:

<select..onchange() > With Only One <option>

Sep 27, 2007

I have a bunch of select statements in a form, and each select statement
has an onchange="do_something(this)" in it, and this works
nicely..except when there is only ONE OPTION in a given select.
It seems you cannot 'onchange' a single option!

Well, that is reasonable.

The trouble is I have no way of selecting it since the form itself is a
dummy: The form action is basically to submit to a new script with
hidden variables carefully set to get the desired action depending on
the last option selected Code:
