JavaScript - Dynamically Remove Options From Dropdown. How To Return To Original Dropdown List?
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: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

Many thanks! Martin Similar TutorialsHi, 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! Joe Hi, I have two dropdown lists, and I want to have each option from the first dropdown list to give the specific options on the second dropdown list. For instance, <select name="module"> <option value="pic1.jpg>TM1</option> <option value="pic2.jpg>TM2</option> <option value="pic3.jpg>TM3</option> </select> <select name="location"> <option value="loc_1">Box1</option> <option value="loc_2">Box2</option> <option value="loc_3">Box3</option> Note: The option values are just examples, but each option must have a value in order for other things to work. Here is what I need to do: If TM1 is selected, only Box1 and Box 2 are available (Box3 is removed from the dropdown "location" list); If TM2 is selected, only Box 2 is available (Box 1 and 3 are removed from the dropdown "location" list); If TM3 is selected, all options in the dropdown "location" list are available. My javascript knowledge is very limited. Any help is greatly appreciated. Thanks in advance, JW Using Javascript / jQuery, I'm trying to produce a series of dropdowns ("<select>") that have their options filtered as the user selects from them. For example: DROPDOWNS Field 1: - value_1 - value_2 Field 2: - value_3 Field 3: - value_4 - value_5 COMBINATIONS - value_1, value_3, value_5 - value_1, value_3, value_4 - value_2, value_3, value_5 When a user selects Field 3 - value_4, the unavailable options will be removed - ie, Field 1 - value_2 (there is no combination that allows value_2 and value_4 to be selected together). I have an array of the allowed combinations like this (although I can tweak the structure if necessary): Code: var combinations = [["value_1", "value_3", "value_5"], ["value_1", "value_3", "value_4"], ["value_2", "value_3", "value_5"]]; When a option is changed all the current entries are removed and only the allowed combinations added back in. Where I'm struggling is with how to find which combinations are acceptable based on what has already been selected. I'd really appreciate any pointers or just a fresh perspective on this because I seem to be going round in circles! Thanks! Hi! I have the following javascript and accompanying html but the i keep getting the error: Unable to get value of the property 'options': object is null or undefined pointing to this line of the code " $thisSelectedValue = $formField.options[ $formField.selectedIndex ].value;" Can someone help me please... thanks in advance.

This works very well.. but i need the dt a span show me the value of the current li (<li class="current-menu-item">), so instead "Select a Field" must say "All Fields" (current value in this example), and when i go to "Motion Graphics" (for example), when page is load must say "Motion Graphics". Can i do this adding a variable to take the value of current li and droping when document.ready? Thanks Hello, I have been looking for this all day - Change currencies throughout the page when choosing between countries or currencies from dropdown menu. What I basically need is a dropdown menu which shows countries or currencies. When you select anyone of it like USD all the prices throughout the page are changed to USD. Now if you change it AUD/CAD/PKR etc they will be changed accordingly. A very good example of this is: http://creativeon.com. When you change currency from right top dropdown menu - it changes the currencies of all the packages in the main content. I am a HTML developer and do not know much about javascripting. Please help me. P.S. I have searched codingforums.com too and found only two links which are not of my use because they are currency converter: http://www.codingforums.com/showthread.php?t=196577 http://www.codingforums.com/showthread.php?t=196373 Best Regards and 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))
{

$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>");
}

It's probably obvious to you guys!! Thanks in advance for your help. 09-01-10 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.

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.

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”” Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>JukeBox</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="Expires" content="-1"> </head> <body> <IFRAME name="frame" src="JukeboxList.m3u" width="100%" height="347" scrolling="no" frameborder="0"> [Your user agent does not support frames or is currently configured not to display frames.] </IFRAME> </body> </html> Thanks!

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. another.html Code: <html>

--cars.js contained in next post-- 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." 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 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">

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 I just recently bought 2 books, AJAX and Javascript, to help me in writing a wep application. They have been great so far except for one thing. I am trying to populate a dropdown list with an XML file, but I want it to load into the dropdown list only AFTER a radio button has been clicked. Does anyone know how to do this or does anyone know where I could go to get some insight on this? Thanks.
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 Hi all, I want to reload an html page onChange event of dropdown list and retain the old values filled in the page. Plz help..... hey guys The first dropdown has some options as : abc(a) bcd(a) cde(b) def(b) efg(c) fgh(c) The second dropdown has : a b c On selecting abc(a) in first dropdown the 'a' must get selected in second dropdown,on selecting cde(b) second dropdown must have 'b' and so on,also the second dropdown value should be disabled(grayed out) for user.Need the code in javascript.ty in advance.

How can I execute this: From the dropdown list build up from mysql database (say a list of fruits). I select "Add New Fruit". This triggers it to either have a modal form to add new fruit or a table form. Once submitted, Select dropdown list RELOADS including the newly added data (fruit) without reloading the whole page which contains other form control such as textbox. |
