JavaScript - Changing The Default Of A Dropdown List Depending On The Url You Are Coming From

Hi,

I have two dropdown lists with the second one being dependent on the selection in the first.

Options in list 1:
1,3 or 4

List two should be enabled when 3 or 4 is selected in list 1.

So far so good, managed to get it to work with only one set of lists, but I actually have 18 of those sets in this form:

Code:

<select name="fw[$i]" id="fw[$i]">
<option value="1">FWH</option>
<option value="3">links</option>
<option value="4">rechts</option>
<option value="0" selected></option>
</select><br />
<select name="lie[$i]" id="lie[$i]" disabled="disabled" onchange="showBox($i,xxx);">
<option value="0" selected>---</option>
<option value="1">gut</option>
<option value="2">schlecht</option>
<option value="3">Strafschlag</option>
<option value="4">OB</option>
</select>

$i is my index generated by my PHP script and runs from 1 to 18.
Everything works just fine as long as the index is not in play. With the index my function breaks, most probably due to my inability to extract the second parameter (xxx above) from the selection field.

Here's my function, there could be something wrong there too with how exactly to specify the proper dropdown list to enable.

Code:

function showBox(field,val) {
		
if (val > 1) {		
var box = 'lie[' + field + ']';
document.form1.box.disabled == false;
}
else {
document.form1.box.disabled == true;
}
	
}

Finally, I'm not that adept in javascript programming, more like a trial and error guy, how has hit the wall with this problem.
Thanks in advance!

hello
i have this code that tags between three images in an certain amount of time
and this works fine
Code:

<script language = "Javascript">
<?php $count_im=1;
 $req=mysql_query("select * from banner");
	while ($res=mysql_fetch_array($req)){ ?>
var image<?php echo $count_im; ?> =new Image()
image<?php echo $count_im; ?>.src="<?php echo $res["banner"]; ?>"
<?php $count_im++;
}?>
</script>

Code:

<div class="banner">
	<p class="banner_image">
		<img src="banner/12.jpg" name="slide" width="290px">
		<script>
			<!--
			//variable that will increment through the images
			var step=1
			function slideit(){
			//if browser does not support the image object, exit.
			if (!document.images)
			return
			document.images.slide.src=eval("image"+step+".src")
			if (step<3)
			step++
			else
			step=1
			//call function "slideit()" every ... seconds
			setTimeout("slideit()",10000)
			}
			slideit()
			//-->
		</script>
	</p>
</div>

and i want it also to tag between hrefs too, so tried the following but didnt work
Code:

<?php $count_im=1;
 $req=mysql_query("select * from banner");
	while ($res=mysql_fetch_array($req)){ ?>
var image<?php echo $count_im; ?> =new Image()
image<?php echo $count_im; ?>.src="<?php echo $res["banner"]; ?>"

var link<?php echo $count_im; ?> =new String()
link<?php echo $count_im; ?>.href="<?php echo $res["banner_title"]; ?>"

<?php $count_im++;
}?>

Code:

<div class="banner">
	<p class="banner_image">
		<a href="" rel="nofollow" target="_blank" name="links">
		<img src="banner/12.12" name="slide" width="290px"></a>
		<script>
			<!--
			//variable that will increment through the images
			var step=1
			function slideit(){
			//if browser does not support the image object, exit.
			if (!document.images)
			return
			document.images.slide.src=eval("image"+step+".src")
			document.a.links.href=eval("link"+step+".src")
			if (step<3)
			step++
			else
			step=1
			//call function "slideit()" every ... seconds
			setTimeout("slideit()",10000)
			}
			slideit()
			//-->
		</script>
	</p>
</div>

anyone can help???

Hi coders,

I need to achieve two things upon making a selection from a drop down field:

1) Changing the background picture of a cell.
2) Changing the size of a uploaded foreground picture within the same cell.


Code:

<select name=ADDITIONALINFO> 
<option value="25 x 25">25 x 25</option> 
<option value="35 x 35">35 x 35</option> 
<option value="45 x 45">45 x 45</option> 
<option value="55 x 55">55 x 55</option> 
</select>

Any guidance how to achieve this is appreciated.

Hi,

I'm trying to integrate an address finder (http://www.craftyclicks.co.uk/) into my shopping cart (OsCommerce). I can get it to work but I need to add my own functionality. I'm not very experienced with JavaScript and my head has entered an infinite loop by now.

The problem is that the address finder script can change the selected country in a drop-down list depending on the postcode entered by the user (using the onblur event handler). What I need it to do is to remove all other countries depending on the postcode. I can get it to remove all other countries but how do i return to the original list of countries when the postcode is changed again? Once all other counties are removed, the drop-down list will obviously only have one option left... I guess the question is also how does a function remember what it has done before, when it is called again?

I have written this short test script as it is easier to work with than the craftyclicks oscommerce contribution:

Dear Javascript programmers,

Do you have an example of a Javascript something like this:

A dropdownlist with values "one" and "two". The radio button is not visible (as a start).
- If you have selected "one" from the dropdown list, then a radio button will appear.
- If you have selected "two" from the dropdown list, then a radio button will NOT appear.

Thanks,

Hello.

The code below lets a user select a drop down option and a picture changes depending on the selection. I am trying to make it so when you select an option on the dropdown the picture shows up in the center of the screen and in the background behind the text.

Here is the code.

Code:

<html>
<head>
<style type='text/css'>

#txt {background-repeat:no-repeat;width:200px;height:200px;}
</style>

<script type='text/javascript'>
function div_bg(team){
	document.getElementById('txt').style.backgroundImage="url(images/" + team + ".jpg)";	
}
</script>

</head>

<body>
<select name='team' onChange='div_bg(this.value);'>
<option name='arsenal' value='arsenal'>Arsenal</option>
<option name='liverpool' value='liverpool'>Liverpool</option>
</select>
<div id='txt'></div>
</body>

Thanks in advance!!

Hi all,

I have been struggling on a bit of code for a while now. I need to populate a second drop down list (Region) based upon the selection of the first (County).
I have found a piece of code that works on its own and have adapted to suit my needs - see below. However, when I drop it into my main page the javascript is not working. It's because of the formObject but I just don't know enough to resolve this! Furthermore, I need the textboxes the user has already completed in the form to retain their value once the javascript kicks in as the completed form will submit to a database.

This piece of code is working well . . . .
Code:

<?php

$link = mysql_connect('myhost', 'myusername', 'mypassword') or die('Could not connect: ' . mysql_error());
mysql_select_db('mydatabase') or die('Could not select database');

if(isset($_GET["County"]) && is_numeric($_GET["County"]))
{
$County = $_GET["County"];
}

if(isset($_GET["Region"]) && is_numeric($_GET["Region"]))
{
$Region = $_GET["Region"];
}

?>

<script language="JavaScript">

function autoSubmit()
{
var formObject = document.forms['theForm'];
formObject.submit();
}

</script>

<form name="theForm" method="get">

<!-- County SELECTION BASED ON city VALUE -->

<?php

?>

<select name="County" onChange="autoSubmit();">
<option value=''</option>

<?php

//POPULATE DROP DOWN MENU WITH COUNTRIES FROM A GIVEN city

$sql = "SELECT * FROM county_regions";
$counties = mysql_query($sql,$link);

while($row = mysql_fetch_array($counties))
{
echo ("<option value=\"$row[CountyID]\" " . ($County == $row["CountyID"]? " selected" : "") . ">$row[County]</option>");
}

?>

</select>

<?php

?>

<br><br>

<?php

if($County!= null && is_numeric($County))
{

?>

<select name="Region" onChange="autoSubmit();">


<?php

//POPULATE DROP DOWN MENU WITH RegionS FROM A GIVEN city, County

$sql = "SELECT * FROM county_regions WHERE CountyID = $County ";
$Regions = mysql_query($sql,$link);

while($row = mysql_fetch_array($Regions))
{
echo ("<option value=\"$row[CountyID]\" " . ($Region == $row["CountyID"]? " selected" : "") . ">$row[Region]</option>");
}

?>

</select>

<?php

}

?>

What follows is my form where the javascript is not working - edited quite a bit to save on space!

Code:

<head>
 
<script language="JavaScript">

function autoSubmit()
{
var formObject = document.forms['subform'];
formObject.submit(); 
}

</script>

</head>

It's probably obvious to you guys!!

Thanks in advance for your help.

Not sure exactly where to post this thread as it involves HTML, Javascript and embedded media players. It probably would be more appropriate here as there is much Javascript involved....

Hello,

I am trying to construct a Jukebox for my website. I have spent considerable time all over the WEB and at this forum which addressed the issue in a 50 page thread. Please see:

http://codingforums.com/showthread.php?t=50666

I got a lot of ideas from this thread but still cannot figure a way to do the following within the Jukebox. These are my main two questions for everything below:

1. How can I have the Jukebox cycle through all tunes and then start over from the beginning?

2. How can I allow the user to select a tune from a list but not a drop down list, have the Jukebox start from the user’s selection and then play all songs to the end. Then as in #1, start over from the beginning?

Per this thread I came away with basically two ways to assemble the jukebox. One uses links in a drop down list which the user can choose from. The other is to use an .m3u playlist. The user can only select a “playlist” from the drop down.

Below, I have included the code for each Jukebox. To see the Jukeboxes in action please go to my website where I have posted some test pages exhibiting the jukeboxes that I am referring to.

The following is the Jukebox which utilizes an .m3u playlist. If I end up using this idea I would like the tunes in the .m3u playlist to be displayed and allow the user to be able to choose a tune in the list. Then have the list play to the end of all tunes in the list. Then start over from the beginning of the list. After this code is the .m3u playlist.

Go to url removed and click on the link that says:
“Media Player Using an .M3U Playlist”

Here is the .m3u playlist for the above code:


Code:

#EXTM3U
#EXTINF:Bill Evans - G Waltz
media/G Waltz.mp3
#EXTINF:Dan Pincus - In Your Time
media/In Your Time.mp3

The following code is for the Jukebox that has a list of links in a dropdown list. If I go with this idea, I would like for the list not to be a dropdown list but just a list of tunes. The user should be able to click on any tune in the list and the player should start from that point, play all the remaining tunes in the list and then start from the beginning.

Go to url removed and click on the link that says:

Another idea I found on the WEB also uses an .m3u playlist. The good thing about it is that it lists all the tunes in the playlist which the user can then select from. This jukebox calls up an entire Windows Media Player. If I was to use this idea I would like to be able to disable the left side of the player where the user has options such as burning to CD, Media Guide, Radio Tuner etc…

Go to url removed and click on the link that says:
“Media Player Within an IFrame Using .m3u Playlist””

I need help with this js...
this is dropdown list...if user choose okc in first list(vrsta) in second (celik) user can choose C0270 and C0370...if chosen pc in first list in second user can choose C1330 and C1530 etc...
There are two boxes...ans15 and ans14...and button which user clicks
The idea is that user choose one option(okc,pc or cc) and choose option (C0270 or something else) onclick some values should be written in boxes
example:
chosen okc and C0270 in ans15 "hello" and in ans14 "goodbye" should be writen
if chosen okc and C0370 in ans15 "hi" and in ans14 "bye" should be writen


Code:

<script type="text/javascript">
function setOptions(chosen) {
var izbor = document.form3.celik;
izbor.options.length = 0;
if (chosen == " ") {
  izbor.options[izbor.options.length] = new Option('choose',' ');
 
}
if (chosen == "okc") {
  izbor.options[izbor.options.length] = new Option('C0270','C0270');
  izbor.options[izbor.options.length] = new Option('C0370','C0370');
}
if (chosen == "pc") {
  izbor.options[izbor.options.length] = new Option('C1330','C1330');
  izbor.options[izbor.options.length] = new Option('C1530','C1530');

}
if (chosen == "cc") {
  izbor.options[izbor.options.length] = new Option('C1120','C1120');
  izbor.options[izbor.options.length] = new Option('C1220','C1220');

 }


}

Howdy,

So I have some javascript/html on one file (another.html) that I would like to split into two separate pages:

home2.html
cars.js

If you view the code for home2.html everything works up until the model form box. That's where my problem lies. I can get the code to work on another.html but I'm splitting it up incorrectly in home2.html

Help would be much appreciated.

PS: If you are going to gripe at me for not using PHP or SQL to make things easier (for future updates to code) at least link me to something to learn from then insult me.

--cars.js contained in next post--

Hi,
I have a table displaying records from query, now i want to have a small dropdown listbox on the top right corner called "sort by". The list index would be "date modified", "Price(High-low)" and "Price(Low-High)".
I want my order by clause in my SQL to change according to the values in the dropdownlistbox.
Code:

SELECT * FROM Cars
ORDER BY date modified

How can i pass my selected value from the listbox to my PHP SQL statement?
Thanks

I play a text game that allows you to input javascript into a "QuickBar" set up for links. I currently have a couple of short "links" set up to fill in a form for me, but I am trying to do something else now.

An example for one I use that fills in a specific blank text area:
javascript: var doc=document; if(window.frames.length>0) doc=window.main.document; doc.getElementsByName('light')[0].value=40; doc.getElementsByName('Okay')[0].click(); end();

On a different page than the empty text areas, there is a fixed drop down select with 5 choices, and I would like to set up a 6th choice using the same insert javascript "link" system.

Code:

<tr>
<td>Map size:</td>
<td><select name="map_size">

<option label="7x7" value="7">7x7</option>
<option label="9x9" value="9">9x9</option>
<option label="11x11" value="11">11x11</option>
<option label="13x13" value="13">13x13</option>
<option label="15x15" value="15" selected="selected">15x15</option>

</select></td>
</tr>

What I would like to do is set up another javascript "link" that will add a "30x30" option to that list and be able to select it after clicking the javascript "link."

hello,

i am writing a script that will update a dropdown list based on the selection of a previous list.

the script is run by a PHP script, so instead of posting the PHP, i will post an example client-side script.

the hierachy is:

category, sub category, brand (but sometimes there exists no sub category and the PHP script queries and adds brands instead)
everything works correctly, except for one major issue: you can not change the selection of the third (brand) box

this could be an easy fix for some coders, but i am not experienced in javascript and could really use some help.

here is an example script, sorry it is so long
Code:

<script language="javascript"> 
 
 
function fillprodCat(){

please let me know if this is too confusing to follow (because it certainly looks like it could be), and i will attempt to clean it up

HI
I'm using this form in my site, but I want to amend it so the form updates based on the option ID, not the option Value.

This will make it easier for me to save the correct data in the value field..

Any ideas ?

PHP Code:
<html>
<head>
<script type="text/javascript">
function setOptions(chosen) {
var selbox = document.myform.opttwo;
 
selbox.options.length = 0;
if (chosen == " ") {
  selbox.options[selbox.options.length] = new Option('Please select one of the options above first',' ');
 
}
if (chosen == "1") {
  selbox.options[selbox.options.length] = new Option('first choice - option one','oneone');
  selbox.options[selbox.options.length] = new Option('first choice - option two','onetwo');
}
if (chosen == "2") {
  selbox.options[selbox.options.length] = new Option('second choice - option one','twoone');
  selbox.options[selbox.options.length] = new Option('second choice - option two','twotwo');
}
if (chosen == "3") {
  selbox.options[selbox.options.length] = new Option('third choice - option one','threeone');
  selbox.options[selbox.options.length] = new Option('third choice - option two','threetwo');
}
}
</script>
</head>
<body>
<form name="myform"><div class="centre">
<select name="optone" size="1"
onchange="setOptions(document.myform.optone.options[document.myform.optone.selectedIndex].value);">
<option id="0" value=" " selected="selected"> </option>
<option id="1" value="1">First Option</option>
<option id="2" value="2">Second Choice</option>
<option id="3" value="3">Third Choice</option>
</select><br /> <br />
<select name="opttwo" size="1">
<option value=" " selected="selected">Please select one of the options above first</option>
</select>
<input type="button" name="go" value="Value Selected"
onclick="alert(document.myform.opttwo.options[document.myform.opttwo.selectedIndex].value);">
</div></form>
</body>
</html> 


So how do I get CHOSEN to equal the ID not the value ?

Thanks
