The page consists of 2 dropdowns and one checkbox.
The checkbox options in Q03 should depend according to the user selections in Q01 and Q02.
As an instance, if the user selects "shower" in the Q01 and "Burke" as the design in the Q02.
In that case, Q03 should be a single specific checkbox value.

Even there are no console errors when it runs via the browser the expected result won't be shown.
It is expected to get different checkboxes in those 2 instances.
You have manythings going wrong here,
value="showers " should be value="showers" (without space)
You should not use index as the the check
Take a look at this code, I have added one condition you can add other as per your requirement.
$('#build,#design').on('change', function() {
var amount = $('#build').val();
var designVal = $('#design').val();
//alert(amount);
if (amount == 'showers' && designVal == 'Burke') {
$("#append_checkbox").html('<input type="checkbox" name="designs[]" value="13mm Compact Laminate only"/>13mm Compact Laminate only');
}
//your other conditions

I have two different select elements. One where a user select their gender and the second where a user selects a place they live.
I have;
<select class="selectGender" name="gender" id="styleSelect" required>
<option value="">None</option>
<option value="male">Male</option>
<option value="female">Female</option>
</select>
and
<select class="selectPlace" name="place" id="styleSelect" onchange="return checkGender()" required>
<option name="dorm" value="">None</option>
<option name="dorm" value="town" name="">Town</option>
<option name="g" value="city">City</option>
</select>
What I want is that when a user selects male as gender and selects town from other select element, he should get an alert "not allowed".
Here's what I have done so far but I get nothing from this.
function checkGender() {
let gender = document.getElementsByName('gender');
let place = document.getElementsByName('place');
if (gender.value == "male" && place.value == "town") {
alert("Not allowed");
}
}
You have error on your html code check this
enter code here
<select class="selectGender" name="gender" id="styleSelect" required >
<option value="">None</option>
<option value="male">Male</option>
<option value="female">Female</option>
</select>
enter code here
<select class="selectPlace" name="place" id="styleSelect1" onchange="checkGender()" required>
<option name="dorm" value="">None</option>
<option name="dorm" value="town">Town</option>
<option name="g" value="city">City</option>
</select>
<script>
function checkGender(){
let gender=document.getElementsByName('gender')[0].value;
let place=document.getElementsByName('place')[0].value;
console.log(gender);
console.log(place);
if (gender=="male"&&place=="town") {
alert("Not allowed");
}
}
</script>
Couple of errors with your code:
You can't have two or more elements with the same id but both of your selects have id="styleSelect".
You should add the checkGender() function to your first select too, as users not necessarily choose the second select last. Changing the first select should also fire the handler to check the values of the options.
As others have mentioned, getElementsByName returns a NodeList collection of elements with the given name. It means, you need to grab the element at the zeroth index.
You can check the working code below by clicking on the "Run code snippet" button:
function checkGender() {
let gender = document.getElementsByName('gender')[0];
let place = document.getElementsByName('place')[0];
if (gender.value === "male" && place.value === "town") {
alert("Not allowed");
}
}
<select name="gender" onchange="checkGender()" required>
<option value="">None</option>
<option value="male">Male</option>
<option value="female">Female</option>
</select>
<select name="place" onchange="checkGender()" required>
<option value="">None</option>
<option value="town">Town</option>
<option value="city">City</option>
</select>
Try
document.getElementsByName('gender')[0].value
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.)
I'm new to Javascript and I'm trying to link two comboboxes ! In the first combo box I have the names of some states in greece and in the other the cities ! In the second I have all the cities in Greece and I want when I select a state from the first combo box only certain cities to appear on the second ! For example if I select Attikis , then I want to be shown in dropdown menu only Agias Paraskeuis and not Agias Varvaras and Agiou Dimitriou and vice versa !
My code is this :
<form action="?" method="get">
<div class="jtype">
<label for="nomos"> Νομός </label>
<form name="nomoi_poleis" action="">
<select id="combo_nomoi" name="combo_nomoi" onchange="cityChange()" >
<option value="attikis"> Attikis</option>
<option value="thessalonikis"> Thessalonikis</option>
</select>
<br></br>
<label for="poli">Πόλη</label>
<select id="poleis" name="poleis">
<option value="agias varvaras"> Agias Varvara</option>
<option value="agias paraskeuis">Agias Paraskeuis</option>
<option value="agiou dimitriou"> Agiou Dimitriou</option>
</select>
</form>
</div>
</form>
Ana my JS :
<script type="text/javascript">
function changeCity(){
var nomos = document.getElementById("combo_nomoi");
if (nomos.value == "attikis"){
document.getElementById("attikis");
}
else{
document.getElementById("thessalonikis");
}
}
</script>
0The easiest way is to have a set of <select> menus, all but one of which has its display property set to none, with the one you want to display set to inline. Then in your onchange handler you run through your list of selects in a loop, setting the display property accordingly. Note inline event handlers like that are not very good practice; better to set them up via JavaScript in your page initialisation code. It misght look something like:
(HTML)
<select id="states">
<option value="0" selected="selected">State 1</option>
<option value="1">State 2</option>
...
</select>
<select id="cities_0" style="display: inline;">
<option value="...">Name 1</option>
<option value="...">Name 2</option>
...
</select>
<select id="cities_1" style="display: none;">
<option value="...">Name 1</option>
<option value="...">Name 2</option>
...
</select>
JavaScript
function change_city(evt)
{
var states=document.getElementById('states'),whichstate;
whichstate=states.options[state.selectedIndex].value;
for(var i=0;i<states.options.length;i++)
document.getElementById('cities_'+i).style.display=(i==whichstate ? 'inline' : 'none');
}
The following is a crude example(using only JS) to get this working:
http://jsfiddle.net/FMZ2H/
HTML
<form action="?" method="get">
<div class="jtype">
<label for="nomos">Νομός</label>
<form name="nomoi_poleis" action="">
<select id="combo_nomoi" name="combo_nomoi">
<option value="attikis">Attikis</option>
<option value="thessalonikis">Thessalonikis</option>
</select>
<br></br>
<label for="poli">Πόλη</label>
<select id="poleis" name="poleis">
<option id="option1" value="agias varvaras">Agias Varvara</option>
<option id="option2" value="agias paraskeuis">Agias Paraskeuis</option>
<option id="option3" value="agiou dimitriou">Agiou Dimitriou</option>
</select>
</form>
Javascript:
document.getElementById("combo_nomoi").onchange = cityChange
function cityChange() {
var elem = document.getElementById("combo_nomoi");
if (elem.options[elem.selectedIndex].text == "Attikis") {
document.getElementById("option1").disabled = true;
document.getElementById("option2").disabled = false;
document.getElementById("option3").disabled = false;
}
if (elem.options[elem.selectedIndex].text == "Thessalonikis") {
document.getElementById("option1").disabled = false;
document.getElementById("option2").disabled = true;
document.getElementById("option3").disabled = true;
}
}
As shown above, you could disable the options you don't want your user to select. I'll leave it to you to do it an better way than selecting each option by their id.
I'm working on a website project and really need help as I'm new to all this. I'm basically given values to every option in the drop down menu's and make them add together which I've managed. But then I want to the total value from the menus to then be the range for a pseudo random to be a generated and added to the age I input.
When I hit submit I'd like it to calculate all that and display the result on a new page. I want to be able to do all this within javascript and html.
Any help would be greatly appreciated! My coding is below. Thanks so much!

I played with your code. I don't now if it's someting like that that you wanted but here is an example of random score.
It now use the age to generate a value.
Take a look if you like it at my codepen.
I changed the age input:
Age<input id="age" name="" type="number" value="" />
I also added a new function to generate random number between min-max:
function getRandomInt (min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
}
And modified how the sum is calculated:
var age = document.getElementById('age').value;
sum = parseInt(age) + parseInt(getRandomInt(sum-(age / 4),sum+(age / 4)));
//Add some random. The more you are older, the more random it is.
You can do a lot of different generated sum. If you want less modifications, we also can take the last digit of the age to get the min/max value generated...
Edit:
To help you share variables between pages, Look at this question.
Adding this as an answer as the submitter considers it a good idea:
Put the result from all your maths into hidden fields. Then when you submit the form, the values will be passed along.
You don't need to do anything special really. Just add fields like this:
<input type="hidden" value="[yourValue]" name="fieldName" id="fieldId" />
For the yourValue part, simply insert your caclulated value from the JavaScript:
document.getElementById("fieldId").value = calculatedValue;
Since it's all part of the same form that you're submitting anyway, they will all be past along. You can retrieve the fields on the receiving page as normal.
I downloaded and edited your entire code block. I changed a couple of things.
1. You don't need the onsubmit on your form. You need a call the JavaScript function on a Total button. The submit button is added to submit the form when the user is done.
2. A hidden field to hold your result is added to the form.
3. The function where you do your calculation has an addition to send the calulated total to the new hidden field.
4. You need to add something to the ACTION, so it knows where to submit the form. You can also remove the ALERT. I just added that to be sure it worked right.
I've run and tested this, and it works exactly as expected. This is what the edited code looks like:

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?
