JavaScript - Need To Get Two Dropdown Box Combinations To Sawp Images In A Div!
I need to know how I would go about making it so that when people select an option like men it populates a different set of dropdown options in the second dropdown (and a different set of options if I select women, etc...), and then I can select an option like Hair Care Products and have it swap out the image in a div to show mens hair care products. I have code to do this for just one dropdown, but I don't know how to make it work with two dropdowns that populate different info based on the selection of the first dropdown. Any help given would be much appreciated.
Code: <label>
<select name="menu" id="menu">
<option value="Men" selected="selected">Men</option>
<option value="Women">Women</option>
</select>
</label></td>
<td align="left"><label>
<select name="type" id="type">
<option value="Hair Care Products" selected="selected">Hair Care Products</option>
<option value="Combs and Brushes">Combs and Brushes</option>
</select>
</label>
<div id="show_picture"><img src="picture1.gif" width="40" height="40" /></div>
Similar TutorialsUsing 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! I looked around for a solution but could not find one. I am trying to find combinations of numbers that can add up to a total. The numbers available and the total are different each time. For example, I have an array that contains the following numbers: [16,12,8,6,4,2] I want to find the combinations that add up to 140, like this: 8x16,1x12 8x16,1x8,1x4 11x12,1x8 Notice I do not do: 8x16,2x6 8x16,3x4 This is because as a rule, only the first number can be used in multiple of more than one. All other number pairs can only be a 1x. Output string could be formatted like this in a single string containing all combinations: 8x16,1x12|8x16,1x8,1x4|11x12,1x8 The code I will am including is far from finished, but some of what I do have works (the "submit" code does not work yet). I am able to prevent certain kinds of input including Shift-Ins pasting, but Ctrl-v pasting still works (and I do not want it to). Could you please tell/show me what code needs to be entered to my existing functions, or what new function I need to create (and call from my existing functions) to eliminate any kind of CtrlKey input?

The form has two different select boxes and based on your options selected for select box #1 and select box #2, the hidden input field "redirect" (which is currently empty) would then populate dynamically with the URL associated with that combination mentioned below. The hidden redirect input field (now containing dyanmically generated data) would then pass the new value via HTTP_POST to .net script that will handle the redirect processing step fed to it. Here are the mappings: If selections = Elementary & Vocabulary = http://www.widget.com/content/elem-vocab If selections = Elementary & Writing = http://www.widget.com/content/elem-writing If selections = Elementary & ELD = http://www.widget.com/content/elem-eld If selections = Middle School & Vocabulary = http://www.widget.com/content/midscl-vocab If selections = Middle School & Writing = http://www.widget.com/content/midscl-writing If selections = Middle School & ELD = http://www.widget.com/content/midscl-eld If selections = High School & Vocabulary = http://www.widget.com/content/hiscl-vocab If selections = High School & Writing = http://www.widget.com/content/hiscl-writing If selections = High School & ELD = http://www.widget.com/content/hiscl-eld Here's a snippet of a different method that I tried, but it did not work. I think the above mentioned method would probably be best. Code: <script language="javascript" type="text/javascript">

document.fillgaps.redirect.value = "http://www.widget.com/content/" + document.fillgaps.grade.value + "-" + document.fillgaps.solution.value ;

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 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. Hello, I am completely new to HTML/JS/CSS, therefore I know very little. I have two drop-down prompt controls with month names. One has just one value (say "July") and the other has all the months of the year ("January".."December"). The first prompt control is hidden on the page. How do I set the default selection of the second prompt control to the value present in the first prompt control? So, when the page is run, the second prompt control should automatically show "July". I was reading up on the selectedIndex property (?), but I know that it won't work because I want Index 0 to be selected in the first control and Index 6 in the second, and I expect it to change every month (next month it will be index 7 that should be automatically selected). If it matters, I am using IE8. Thanks! 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! Joe Hey everyone! I'm in the process of creating a portfolio site for my artwork and I'm requesting help. The website has a scalable JQuery background which changes depending on which thumbnail you click. I've uploaded the progress he http://www.aldousmassie.com/newprogress I'm using this code at the moment to scroll through the background: Code: <!-- SCRIPT FOR CHANGING BG ON CLICK -->

Unfortunately, the bottom code overwrites the top. Is it possible for each different background image to have their own "set" of images that could be scrolled through onclick? I'd appreciate any tips that point me in the right direction. Thank you. Hi there, I've been searching for an answer to this for the last few days but with no luck, so I thought I'd register here to see if anyone can possibly help. All I've been able to find everywhere for this is examples of changing images when rolling over them or clicking them, and I don't need that. What I need is a bit of javascript that will recognise some image paths on a page and replace those image paths with other ones. It's for an ecommerce website on a certain platform, using a customer reviews section which outputs star images based on the customer's rating. So, the images used (which look awful) are, for example, "sourcehere/stars_5.gif", "sourcehere//stars_4.gif", and so on. Just 5 of them. I want to design my own 5 images, upload those images, and then have the javascript replace the rubbish looking ones on the page with my own images. I thought I'd be able to find something quite easily, but so far all I can find is examples of mouseover events and so on, and I don't need any of that, just the entire image replaced with my own image. Can anyone help please? I'm a beginner with javascript so I'll need it spelled out to me! Thankyou for your time. Please help have a look at the scripts... Where's gone wrong that whenever an image fades out into 0, it reappears before another image comes out? I've wanted to make the image disappear shortly before a new image is loaded. I've worked on this and played around with the scripts, yet no finding... Please do tell me if you know the answer to it. Thanks.

I need a short and simple script a (drop down menu) that I can duplicate about 100-150 times on a page. I need it to be universally compatible IE7-9, Firefox, Chrome, Opera. The one I was originally using worked incredibly slow in IE. Any help would be hugely appreciated and we can figure out a price on the script. Thanks a ton in advance. HI I am trying to add a 'orderby' or 'sortby' dropdown to a website to give various options of order picked from a MySQL recordset, the example below is what I am looking for that changes on re-fresh and remembers the selection chosen. Example Site - Waterstones Bookstore I think it would be a mixture of Javascript and PHP?? I have searched for hours looking for a solution Many thanks in advance Ok i have a question. Is there any way to short down the drop down in "Alphabetical" order. I have a drop down select list which gets its values from mysql DB and i want it to sort it down in alphabetical order to easy selection for the user. Thanks in advance. Hello friends. I need a little help with this code i can't get to work. Under 500.000 euros a link to another website need to open when selected in the dropdown menu.
