Display image based on different values from dropdown options - javascript

I am a little stuck on how I can display images from my image folder based on different values from my options. I want to display images of different drinks based on the users selected options. So if I select Vodka, Sweet, Blended it would display an image of a drink that fits that parameter. I have images saved as the names of the combined values of each group.
ex: "B1X.jpg" would display an image of a boozy frappe.
JS
function displayDrink(src) {
var mixedDrink = $("alcohol").val() + $("flavor").val() + $("type").val() + ".jpg";
}
HTML
<body>
<form>
<select id="alcohol">
<option value="A">Select Alcohol</option>
<option value="B">Vodka</option>
<option value="C">Whiskey</option>
<option value="D">Rum</option>
<option value="E">Tequila</option>
<option value="F">Gin</option>
<option value="G">Bourbon</option>
<option value="H">Scotch</option>
<option value="I">Vermouth</option>
<option value="J">Spirits</option>
<option value="K">Cognac</option>
</select>
<select id="flavor">
<option value="0">Select Flavor</option>
<option value="1">Sweet</option>
<option value="2">Sour</option>
<option value="3">Savory</option>
<option value="4">Spicy</option>
<option value="5">Smoky</option>
<option value="6">Bitter</option>
<option value="7">Fruity</option>
<option value="8">Herbaceous</option>
</select>
<select id="type">
<option value="W">Select Type</option>
<option value="X">Blended</option>
<option value="Y">Iced</option>
<option value="Z">Chilled</option>
</select><br /><br />
</form>
</body>

Have an image tag such as:
<img class="image-container"></img>
select the container:
const container = document.querySelector('.image-container');
subscribe to changes of each of your select elements:
const alcoholSelect = document.querySelector('#alchohol');
const flavorSelect = document.querySelector('#flavor');
const typeSelect = document.querySelector('#type');
alcoholSelect.addEventListener('change', () => handleDrinkSelect());
flavorSelect.addEventListener('change', () => handleDrinkSelect());
typeSelect.addEventListener('change', () => handleDrinkSelect());
add the handler: (make sure to adjust the output string to match the relative location of your images folder)
function handleDrinkSelect () {
container.src = `${alcoholSelect.value}${flavorSelect.value}${typeSelect.value}.jpg`;
}
You could also do it more cleanly with event delegation

How to show/hide items from a select list based on another selection

In JavaScript, how to show/hide items from a select list based on another selected option that contain a certain word or words?
I am very new to JavaScript, so any help would be appreciated.
There are two drop-downs: "group" and "alph".
<select name="group">
<option value="Angry (Two)">Angry (Two)</option>
<option value="Happy (Two)">Happy (Two)</option>
<option value="Sad">Sad</option>
<option value="Tired (One)">Tired (One)</option>
</select>
<select name="alph">
<option value="ABC">ABC</option>
<option value="ABC-1">ABC-1</option>
<option value="ABC-2">ABC-2</option>
<option value="DEF">DEF</option>
<option value="DEF-1">DEF-1</option>
<option value="DEF-2">DEF-2</option>
<option value="DEF-3">DEF-3</option>
</select>
Without IDs, for the first dropdown (name group), if the selected value contains " (Two)", then the list will only show:
<select name="alph">
<option value="ABC-2">ABC-2</option>
<option value="DEF-2">DEF-2</option>
</select>
If the user changes selection, and the selected value contains " (One)", then the list will only show:
<select name="alph">
<option value="ABC-1">ABC-1</option>
<option value="DEF-1">DEF-1</option>
</select>
If the user changes selection, and the selected value does not contain neither " (One)" or " (Two)", then the list will show:
<select name="alph">
<option value="ABC">ABC</option>
<option value="DEF">DEF</option>
<option value="DEF-3">DEF-3</option>
</select>
Note: I am not able to add IDs or attributes. I can only access the name of the select and the value.
Use data-* to create groups, then use a querySelector to get all the options and test if they are apart of the group or not. If they are apart of the group show them otherwise hide them.
// The main group
let groups = document.querySelector('select[name=group]')
// Add a change event
groups.addEventListener('change', (e) => {
// Get the currently selected Group
let current = e.target.options[e.target.selectedIndex]
// Get the data-group number
let group = current.getAttribute('data-group')
// Get all the items from the second dropdown
let opts = Array.from(document.querySelectorAll('select[name=alph]>option'))
// Hide items that are not appart of the group
opts.forEach(itm => itm.style.display = itm.getAttribute('data-group') == group || !itm.getAttribute('data-group') ? 'initial' : 'none')
// Reset the the selection
document.querySelector('select[name=alph]').selectedIndex = 0
})
/* Hide option two items by default */
select[name=alph]>option[data-group]{display:none;}
<select name="group">
<option>Select One...</option>
<option data-group="1" value="Angry (Two)">Angry (Two)</option>
<option data-group="2" value="Happy (Two)">Happy (Two)</option>
<option data-group="3" value="Sad">Sad</option>
<option data-group="4" value="Tired (One)">Tired (One)</option>
</select>
<select name="alph">
<option>Select One...</option>
<option data-group="1" value="ABC">ABC</option>
<option data-group="1" value="ABC-1">ABC-1</option>
<option data-group="2" value="ABC-2">ABC-2</option>
<option data-group="2" value="DEF">DEF</option>
<option data-group="3" value="DEF-1">DEF-1</option>
<option data-group="3" value="DEF-2">DEF-2</option>
<option data-group="4" value="DEF-3">DEF-3</option>
</select>

List displaying different option based on chosen value

I am using the following js and html code to display the lists.
MAIN PROBLEM is that when the sub-categories & categories become to many, the categories change but the sub-categries are not displaying from a certain cagory going downwards. Problem is on desktop/laptops. Working correctly on mobile device. Am not god at javascript
<script type="text/javascript">
$(function() {
$('#vehicle').on('change', function() {
var vehileType = $('#vehicle').val();
$('#vehicle-type option').hide();
$('#vehicle-type option[vehicle="'+vehileType+'"]').show();
});
});
</script>
<select id="vehicle" required name="brand">
<option value="">Select Make</option>
<option value="ABT">ABT</option>
<option value="AC">AC</option>
</select>
<select name="model" id="vehicle-type" class="form-control">
<option vehicle="ABT" value="ABT">ABT</option>
<option vehicle="ABT" value="ABT1">ABT1</option>
<option vehicle="AC" value="AC">AC</option>
<option vehicle="AC" value="AC1">AC1</option>
</select>
First I put vehicle options to custom variable var vehicleTypeOptions = $('#vehicle-type option[vehicle="' + vehileType + '"]');
Then after show I add this $('#vehicle-type').val(vehicleTypeOptions.first().val()); so it will set the value of first vehicle type option
I also put .trigger('change') for a #vehicle so it will set vehicle types by the vehicle make so you don't have to manually set one option
Here is a working demo:
$(function() {
$('#vehicle').on('change', function() {
var vehileType = $('#vehicle').val();
var vehicleTypeOptions = $('#vehicle-type option[vehicle="' + vehileType + '"]');
$('#vehicle-type option').not(vehicleTypeOptions).hide();
vehicleTypeOptions.show();
$('#vehicle-type').val(
vehicleTypeOptions.first().val()
);
}).trigger('change');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="vehicle" required name="brand">
<option value="">Select Make</option>
<option value="ABT">ABT</option>
<option value="AC">AC</option>
</select>
<select name="model" id="vehicle-type" class="form-control">
<option vehicle="ABT" value="ABT">ABT</option>
<option vehicle="ABT" value="ABT1">ABT1</option>
<option vehicle="AC" value="AC">AC</option>
<option vehicle="AC" value="AC1">AC1</option>
</select>

Populate textbox based on Dropdown selection - JavaScript

I have a little question as I'm very new to JavaScript. I've made a dropdown containing various counties, and based on which county is selected, I want a specific email-address to populate a text field. I'm working with the following HTML form:
<div
<br>
Email:
<br>
<input type="text" id="email" readonly=>
</div>
<div>
<br>
Counties:
<br>
<select id="counties">
<option value="Choose One">Choose One</option>
<option value="Charlotte">Charlotte</option>
<option value="Collier">Collier</option>
<option value="Hillsborough">Hillsborough</option>
<option value="Lee">Lee</option>
<option value="Manatee">Manatee</option>
<option value="Pasco">Pasco</option>
<option value="Pinellas">Pinellas</option>
<option value="Polk">Polk</option>
<option value="Sarasota">Sarasota</option>
<option value="Brevard">Brevard</option>
<option value="Broward">Broward</option>
<option value="Indian River">Indian River</option>
<option value="Martin">Martin</option>
<option value="Miami-Dade">Miami-Dade</option>
<option value="Monroe">Monroe</option>
<option value="Palm Beach">Palm Beach</option>
<option value="St Lucie">St Lucie</option>
</select>
</div>
For the first 9 counties; I'd like them to go to "first#email.com
And for the remaining 8 counties; I'd like them to go to "second#email.com
I'm looking for some insight in how to add a value to the counties, and based on that value (Choose One = 0, first nine counties = 1, remaining eight = 2) I'd like to populate the text field with id="email" with the respective email.
How could I go about setting this up in JavaScript? Thanks in advance.
You can do it with custom attribute. See this fiddle: https://jsfiddle.net/y2t0utk7/
Html
<div>
Email:
<br>
<input type="text" id="email" />

<option data-mail="0" value="Choose One">Choose One</option>
<option data-mail="1" value="Charlotte">Charlotte</option>
<option data-mail="1" value="Collier">Collier</option>

<option data-mail="2" value="Monroe">Monroe</option>
<option data-mail="2" value="Palm Beach">Palm Beach</option>
<option data-mail="2" value="St Lucie">St Lucie</option>
</select>
</div>
JS
function setMail(){
// find the dropdown
var ddl = document.getElementById("counties");
// find the selected option
var selectedOption = ddl.options[ddl.selectedIndex];
// find the attribute value
var mailValue = selectedOption.getAttribute("data-mail");
// find the textbox
var textBox = document.getElementById("email");
// set the textbox value
if(mailValue=="1"){
textBox.value = "first#email.com";
}
else if(mailValue=="2"){
textBox.value = "second#email.com";
}
}
Since you said you are new in javascript, let's use a pure javascript way to do it.
You can add an onChange to the select HTML tag and the function you passed in will be triggered every time you change its value.
Inside the function, you can base on the value of the selection, to decide what is the new value for the email box, using switch, if statement etc..
To do what you want, you can use integer be the value as you mentioned.
HTML:
<select id="counties" onchange="func()">
Javascript:
function func(){
var dropdown = document.getElementById("counties");
var selection = dropdown.value;
console.log(selection);
var emailTextBox = document.getElementById("email");
// assign the email address here based on your need.
emailTextBox.value = selection;
}

Html and javascript <select> tags with filtering

I will try to be as specific as I can.
So I need to create a selector that filters the options.
I have:
types of cars
The places where you can drive those cars.
So for example you would select > Ferrari > then the correct areas on the second select tag show up
I.e. Select > Ferrari = London, Cambridge, Devon, New hampshire
Select > Lamborghini = London, Bertshire, Oakwood,
And then finally
they choose (Ferrari + Cambridge) and then press "go" and jump to the final link that will take them to the right page.
My code is:
<script type='text/javascript' src='http://code.jquery.com/jquery-1.6.js'></script>
<script type='text/javascript'>//<![CDATA[
$('#filter-regions').on('click', function() {
var pilotage-carFilter = $('#pilotage-car').text();
var itemFilter = $('#items').text();
console.log('pilotage-carFilter: ' + pilotage-carFilter);
console.log('itemFilter : ' + itemFilter);
console.log('Applying filter now...');
featureList.filter(function(item) {
console.log('Running filter() on item: ('+item+')');
console.log('item.values().pilotage-car: ' + item.values().pilotage-car);
console.log('item.values().item: ' + item.values().item);
return
(pilotage-carFilter==='Ferrari' || item.values().pilotage-car === pilotage-carFilter)
&& (itemFilter==='All items' || item.values().item === itemFilter);
});
return false;
});
//]]>

Im really not sure about javascript at all.
How could I, and/or what is the best way I could achieve this? Are there any examples out there?
EDIT: I found something like this http://jsfiddle.net/dtAgX/1/
But i need a sumbit button that will link to the right page based on selection.
Thanks in advance
You have several options depending on your backend, PHP, ASP ect. or plain HTML.
If you use PHP/ASP you can provide an 'action' and a 'method' for your and have the server provide the correct page, depending on the values of your selects.
If you use plain HTML, you can add an 'onsubmit' event to your and have a javascript redirect to the correct page.
In both cases the "go-button" should be of type "submit".
If you want more help I'll need to know more about your setup :-)
Also, can all cars be driven at all locations?

Cascading Combo box HTML

I am not really a web person and am having trouble creating a cascading combo box. I have my options, but when I cannot figure out how to do a JavaScript command to switch the second box depending on the first box's selection.
These are my first set of options:
<select id="searchType" onchange="selectedOption(this)">
<option value="sessions">Sessions</option>
<option value="files">Files</option>
<option value="clients">Clients</option>
</select>
Depending on what they click there I would like to show these set of options:
SESSIONS
<select id="secondOptions">
<option value="conf">Config ID</option>
<option value="length">Length</option>
<option value="date">Date</option>
</select>
FILES
<select id="secondOptions">
<option value="id">File ID</option>
<option value="length">Length</option>
<option value="sent">Sent</option>
<option value="sessionId">Session ID</option>
</select>
CLIENTS
<select id="secondOptions">
<option value="name">Client Name</option>
<option value="organization">Organization</option>
<option value="specialty">Specialty</option>
<option value="sessionId">Session ID</option>
</select>
And finally a textbox to type into to really specify the search.
Once again, I am trying to do this using JavaScript, but if there is a better way to do this let me know please.
Given the amended html mark-up:
<form action="#" method="post">
<select id="searchType">
<option value="sessions">Sessions</option>
<option value="files">Files</option>
<option value="clients">Clients</option>
</select>
<select id="sessions">
<option value="conf">Config ID</option>
<option value="length">Length</option>
<option value="date">Date</option>
</select>
<select id="files">
<option value="id">File ID</option>
<option value="length">Length</option>
<option value="sent">Sent</option>
<option value="sessionId">Session ID</option>
</select>
<select id="clients">
<option value="name">Client Name</option>
<option value="organization">Organization</option>
<option value="specialty">Specialty</option>
<option value="sessionId">Session ID</option>
</select>
<fieldset id="textAreaSearchBox">
<legend>Search:</legend>
<textarea></textarea>
</fieldset>
</form>
(Note the changed ids, wrapping the form elements in a form, the addition of a fieldset, legend and textarea in the mark-up), the following JavaScript seems to work:
var select1 = document.getElementById('searchType');
var selects = document.getElementsByTagName('select');
select1.onchange = function() {
var select2 = this.value.toLowerCase();
for (i = 0; i < selects.length; i++) {
if (selects[i].id != this.id) {
selects[i].style.display = 'none';
}
}
document.getElementById(select2).style.display = 'block';
document.getElementById('textAreaSearchBox').style.display = 'block';
};
JS Fiddle demo.
