I have a multiple selection box that I would like to use the value's from to display images based on selecting these values, eg. if one value is selected then one image would be displayed, if two are selected two would be displayed etc. I would also like a limit on it of three images displayed at once, no matter how many selections.
<select multiple name="item" class="details" action="post" id="mySelect">
<option value="one">One</option>
<option value="two">Two</option>
<option value="three">Three</option>
<option value="four">Four</option>
</select>
Any help would be greatly appreciated, thank you!
What I've tried so far:
<script type="text/javascript">
<!--
function showimage() {
var htmlStr="";
var option = document.getElementById("selectedValue");
for (i=0;i<option.options.length;i++) {
if (option.options[i].selected) {
htmlStr+='<img src="/products/";
htmlStr+=option.options[i].value;
htmlStr+='" /><br />';
}
}
document.getElementById('mySelect').innerHTML = htmlStr;
}
//-->
</script>
The images are located in /products/..
Don't forget to put correct image paths.
function imageFunc(imageid){
var Imageplace=document.getElementById("myImage");
Imageplace.src=imageid;
}
<select multiple name="item" class="details" id="mySelect" onchange="imageFunc(this.value)";>
<option value="1.jpg">One</option>
<option value="2.jpg">Two</option>
<option value="3.jpg">Three</option>
<option value="4.jpg">Four</option>
</select>
<img id="myImage" src="1.jpg"/>
Change your html to this:
<select multiple name="item" class="details" action="post" id="mySelect" onchange="showimage(this.value)">
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
</select>
And your JavaScript to this:
function showimage(option) {
var htmlStr="";
if(option > 3) {
option = 3;
}
for(i=0;i<option;i++) {
htmlStr+='<img src="/products/' + i + '.jpg" /><br />';
}
document.getElementById('images').innerHTML = htmlStr;
}
All your images should be in the products folder with names: 1.jpg, 2.jpg, ...

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>

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
I'm trying to get multiple drop down boxes to open when selecting different prompts from an original drop down menu.
So for example the original drop box would say "Continent" then drop down to a list of continents, when you select a continent a new box opens that asks you "Country" then you select a country and a new drop box opens to select a state.
I've been using this template
<script type="text/javascript">
function CheckDepartment(val){
var element=document.getElementById('othercolor');
if(val=='others')
element.style.display='block';
else
element.style.display='none';}
function CheckOption(val){
var element=document.getElementById('misc')
if(val=='misc')
element.style.display='block';
else
element.style.display='block';
}
</script>
</head>
<body>
<select name="color" onchange='CheckDepartment(this.value);'>
<option>pick a color</option>
<option value="red">RED</option>
<option value="blue">BLUE</option>
<option value="others">others</option>
</select>
<select name="othercolor" id="othercolor" onchange='CheckOption(this.value)' style='display:none;'/>
<option value=""></option>
<option value="hi">hi</option>
<option value="misc" id="misc" >misc</option>
</select>
<select name="third" style='display:none;'>
<option value=""></option>
<option value="first">first</option>
<option value="second">second</option>
</select>
but I can't get a third drop box to open when selecting an option from the second drop box.
edit: third box. I think i deleted my last try so this was kinda a recreation of it from what I remembered. I'm also incredibly new at all of this and don't know if anything I tried makes sense.
Here's a simplified demo.
(It assumes only a "yes" value should trigger the display of the next dependent dropdown.)
const
select1 = document.getElementById("select1"),
select2 = document.getElementById("select2");
document.addEventListener("change", handleDropdownDisplay);
function handleDropdownDisplay(event) {
let changedElement = event.target;
if ((changedElement != select1) && (changedElement != select2)) {
return;
}
if (changedElement.value == "yes") {
changedElement.parentElement.nextElementSibling.classList.remove("hidden");
} else {
changedElement.parentElement.nextElementSibling.classList.add("hidden");
}
}
div {
margin-bottom: 0.5em;
}
.hidden {
display: none;
}
<div>
<label for="select1">Show level 2?</label>
<select id="select1">
<option value="no">No</option>
<option value="yes">Yes</option>
</select>
</div>
<div class="hidden">
<label for="select2">Show level 3?</label>
<select id="select2">
<option value="no">No</option>
<option value="yes">Yes</option>
</select>
</div>
<div class="hidden">
<label for="select3">Would your rather</label>
<select id="select3">
<option value="brains">Eat monkey brains</option>
<option value="vba">Write code in VBA</option>
</select>
</div>
(Btw, level 3 doesn't automatically become hidden whenever level 2 becomes hidden. This is probably functionality you'll want to add.)
<select class="form-control" id="prodname" name="pname" >
<option value="0" disabled="disabled" selected="selected">-- Select Product --</option>
#{
foreach(var product in (List<tbleProdcutDetail>)ViewBag.productlist)
{
<option value="#product.Id">#product.Product_Name</option>
<option hidden>#product.Quantity</option>
}
}
</select>
I want to select this option.
<option hidden>#product.Quantity</option>
I have tried this selector but could not get text.
var productunitprice = $("#prodname option").find("hidden").text();
You can use var text = $("option:selected",this).next().text() Example below.
$("#prodname").change(function() {
var text = $("option:selected",this).next().text()
console.log(text)
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="prodname">
<option value="1">1</option>
<option hidden>1.1</option>
<option value="2">2</option>
<option hidden>2.2</option>
</select>
As an alternative to adding many unused and hidden options.
You can add the unit price to the relevant option directly using a data attribute for example data-unit-price.
foreach(var product in (List<tbleProdcutDetail>)ViewBag.productlist)
{
<option value="#product.Id" data-unit-price="#product.Quantity">#product.Product_Name</option>
}
Then simply read it from the selected option. In my humble opinion it is cleaner and doesn't use additional hidden option elements as storage for data belonging to other options.
$(document).ready(function() {
$("#prodname").change(function() {
var productunitprice = $("option:selected", this).data('unitPrice')
console.log(productunitprice)
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select class="form-control" id="prodname" name="pname">
<option value="1" data-unit-price="5.25">product 45</option>
<option value="2" data-unit-price="12.99">product 94</option>
</select>
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>
I have a system where you are able to choose a car. You can then choose the transmission and color. Different cars and transmissions bring up different colors. Not sure how to make an image appear of a car when a color is chosen. So for example I choose the rs6 and automatic and then the black color. I would then want an image to appear depending on the color chosen. How would I program it so different cars and colors bring up different images. Im relatively new to coding. Any help would be aprreciated.

$("#car").change(function () {
transmission();
});
$("#trans").change(function () {
transmission();
});
function transmission() {
if ($("#car").val() == "car1" && $("#trans").val() == "auto") {
$("option[value$='red']").hide();
$("option[value$='white']").hide();
$("option[value$='green']").hide();
} else {
$("option[value$='red']").show();
$("option[value$='white']").show();
$("option[value$='green']").show();
}
}
For now it is only working for Audi - Automatic - black and blue to show you the basic idea but it is repeating code and you can do the same for the rest of the cars too.
In this example I am setting the src of the image as the car selected. For example if you select car1 and man and red then src of the image as car1manred.jpg, also I'm changing the alt attribute as well so that you can see the change.
you have to do a lot of manual work. I have created an object for the data that will determine how many cars you have in each category. It would be better if you use JSON for that.
Also I have made car1autoblack (which gets the src of the images) as an array but you can make it as an object and include other things about the cars in this category. for example name, price, availability and much more
$("#car").change(function () {
transmission();

transmission();
selection();
