Checking if all selects are completed in Jquery

I am trying to count the number of VISIBLE selects (Which I've done in the alert in the Jquery) and also count the number of VISIBLE selects that have an option selected. If both numbers match then do some action.
Currently, when I change the first select and choose an option, it doesn't alert with a value. When I change the next select and choose an option it shows the count is 1 when it is meant to be 2. when I select the third select then it shows 3. However these numbers are all inaccurate. What is the cause of this?
<div id="secondPanelID">
<div class="form-group input-group">
<label for="gestationalAgeInWeeks">Gestational Age : </label>
<div>
<select id="gestationalAgeInWeeks" name="gestationalAgeInWeeks" class="form-control">
<option disabled selected value>SELECT</option>
<option value="0">0</option>
</select>
</div>
</div>
<div class="form-group input-group">
<label>days</label>
<div>
<select name=gestionalDays class="form-control">
<option disabled selected value>SELECT</option>
<option value="0">0 Days</option>
<option value="1">1 Day</option>
</select>
</div>
</div>
</div>
Added listeners to each of the selects
$("select[name=gestationalAgeInWeeks]").change(checkingColourSelectsGeneralData);
$("select[name=gestionalDays]").change(checkingColourSelectsGeneralData);
Jquery
var selectCounterInGeneral = 0;
function checkingColourSelectsGeneralData(){
alert($('#secondPanelID select:visible').length)
$('#secondPanelID select:visible').change(function () {
var o = $(this);
if (!o.hasClass('counted')) {
selectCounterInGeneral++;
o.addClass('counted');
}
alert("number of selects: "+selectCounterInGeneral);
});
}

Just check if all visible selects have value this way:
function countSelected(e) {
var toReturn = true;
$('select:visible').each(function(i) {
if( !$(this).val() ) {
toReturn = false;
};
});
console.log( toReturn );
};
$('select').on('change', countSelected);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select>
<option disabled selected value>--choose--</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
<select>
<option disabled selected value>--choose--</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
<select style="display: none;">
<option disabled selected value>--choose--</option>
<option value="1">1</option>
<option value="2">2</option>
</select>

how can i store two info on a single select and call them in separate textbox HTML/JS

<span id="s_home_country">
<select name="Home Country" id="home_country">
<option value="Select one" selected="selected">Select one</option>
<option value="h1">Home1</option>
<option value="h2">Home2</option>
<option value="h3">Home3</option>
<option value="h4">Home4</option>
</select>
</span>
and I have another data that i want to incorporate, when Home1 is selected, I want this to show 21-dec into another textbox automatically. and so on..
var Home_country = [
"21-Dec",
"01-Jan",
"01-Jan",
"01-Jan",
];

You could use an object and an event listener.
var home_country = {
"h1":"21-Dec",
"h2":"01-Jan",
"h3":"01-Jan",
"h4":"01-Jan",
};
var selectbox = document.getElementById('home_country');
var textbox = document.getElementById('home_country_date');
selectbox.addEventListener('change', function(e){
textbox.value = home_country[this.value]
})
<span id="s_home_country">
<select name="Home Country" id="home_country">
<option value="Select one" selected="selected">Select one</option>
<option value="h1">Home1</option>
<option value="h2">Home2</option>
<option value="h3">Home3</option>
<option value="h4">Home4</option>
</select>
</span>
<input type="text" id="home_country_date">

Please find below snippet just add another attribute data-attr1 and on change of select list find selected option and get its attribute with name data-attr1 and pass attribute's value to textbox
$("#home_country").on("change",function(){
$(".txtvalue").val($(this).find("option:selected").attr("data-attr1"));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span id="s_home_country">
<select name="Home Country" id="home_country">
<option value="Select one" selected="selected">Select one</option>
<option data-attr1="21-Dec" value="h1">Home1</option>
<option data-attr1="01-Dec" value="h2">Home2</option>
<option data-attr1="02-Dec" value="h3">Home3</option>
<option data-attr1="03-Dec" value="h4">Home4</option>
</select>
</span>
<input type="text" class="txtvalue" />

Add an event listener to your select input which outputs the relevant value from your array when an option is selected:
var el = document.getElementById('home_country');
var textbox = document.getElementById('your_textbox_el');
el.addEventListener('change', function(e){
if (e.target.value == 'h1') {
textbox.value = Home_country[0];
} else if (e.target.value == 'some other condition') {
// do something else
}
}

Unless I'm misunderstanding you, you can just put the values of the Home_country array inside the value properties of the options like so:
<span id="s_home_country">
<select name="Home Country" id="home_country">
<option value="Select one" selected="selected">Select one</option>
<option value="21-Dec">Home1</option>
<option value="01-Jan">Home2</option>
<option value="01-Jan">Home3</option>
<option value="01-Jan">Home4</option>
</select>
</span>
Now, when you do get the value of your select element, it will be the value in the array that you gave.

Clear check mark and dropdowns when opposite radio button is chosen

How do I clear the checkmark in my checkbox when clicking on the opposite radio button? For some reason I cannot get it to clear will someone please tell me what I am doing wrong? I also would like to know how to reset the dropdowns if there chosen as well I cannot get a good grasp on this syntax I guess :/ $("#div12 > .clearfix input:select").val(""); Where am I going wrong?
function showhideCOREForm(transferring_vehicle_license) {
if (transferring_vehicle_license == "Current") {
document.getElementById("div11").style.display = 'block';
document.getElementById("div12").style.display = 'none';
$("#div12 > #secondYearCB").prop("checked", false);
FC.wantsASecondYear = false;
} else if (transferring_vehicle_license == "Expired") {
document.getElementById("div12").style.display = 'block';
document.getElementById("div11").style.display = 'none';
$("#div6 > .clearfix input:text").val("");
}
}
<input type="radio" value="Current" name="transferring_vehicle_license" id="transferring_vehicle_license" required="yes" onclick="calculateTotal()" onchange="showhideCOREForm(this.value);"/><label for="transferring_vehicle_license">Current Registration</label>
<input type="radio" value="Expired" name="transferring_vehicle_license" id="notransferring_vehicle_license" onclick="calculateTotal()" onchange="showhideCOREForm(this.value);"/><label for="notransferring_vehicle_license">Expired Registration</label>
<div id="div12" style="display:none">

<select name="month2" id="month2" size="1">
<option value="">Choose an Option</option>
<option value="2">2</option>
<option value="14">14</option>
</select>
<select name="month3" id="month3" size="1">
<option value="">Choose an Option</option>
<option value="3">3</option>
<option value="15">15</option>
</select>
<div id="secondYear" class="labelDoubleIndent">
<b>Do you want to add a second year?</b>
Yes: <input type="checkbox" name="secondYear" id="secondYearCB" />
</div><!-- secondYear -->
</div>
</div>
<div id="div11" style="display:none">
</div>

You are using just wrong selector: the #secondYearCB is not a first child of #div12. Use descendant selector instead:
$('#div12 #secondYearCB').prop("checked", false);
The same reason is for select - select is not input! Use just:
$("#div12 > .clearfix select").val("");

Both selectors are wrong to the CHECKBOX and SELECT.
Checkbox, as you are using an ID in it, just use the ID:
$("#secondYearCB").prop("checked", false);
The Selects, they are not INPUT, so use only the "select" word.
$("#div12 > .clearfix > select").val("");
P.s.: I add ">" to get only the direct SELECT childs inner the ".clearfix" div, if you don't want this, just remove it.

How do I set validation on select Tag in my web form?

I want to set validation on select tag in my form so that the user cannot proceed without choosing a location.
Below is the form...
<form name="form1">
Pickup Suburb:
<select id="pick" class="pick" name="pick"/><br />
<option value="none">-- Please select a location --</option>
<option value = 1>City </option>
<option value = 2>Airport </option>
<option value = 3>Abbotsbury </option>
<option value = 4>Abbotsford </option>
<option value = 5>Acacia Gardens </option>
<option value = 6>Agnes Banks </option>
<option value = 7>Airds </option>
<option value = 8>Akuna Bay </option>
</select>
<br />Rear facing baby seat
<select class="rfbs" name="rfbs" style="width:50px">
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
</select><br />
<br />Booster seat
<select class="bs" name="bs" style="width:50px">
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
<br />
<br />Luggage Trailer
<select class="lt" name="lt" style="width:50px">
<option value="0">0</option>
<option value="1">1</option>
</select>
<br />
<br /><input class="show-popup" type="submit" value="Get Quote">
</form>
I have applied a JavaScriptpopup window to show the results when user fills the form so is it possible to apply validation that shows an error message if the user tries to submit the form without choosing a location.
Any help would be highly appreciated.

Because select field has always been chosen value (default first option), you can just check:
if($('#pick').val()=='none') {
alert('choose some value');
return false;
}

The form element allows a onSubmit tag that will get called if the user tries to submit the form.
You could try something like this:
<form onsubmit="checkFormValidity()">
<select id="location" ... >
Then in your javascript you can then do something like this:
function checkFormValidity(){
var select = document.getElementById("location");
if(select.options.selectIndex == 0)
{
return false;
}
return true;
}

One line I would like to add to make sure that form will not be submitted
if($('#pick').val()=='none'){
alert('choose some value');
return false; // this is a missing line
}
Note: To use jQuery, you need to download it and add it to your web form
Edit:
<form id="form1" name="form1" method="post">
Pickup Suburb:
....
</select>
<br /><input class="show-popup" type="submit" value="Get Quote">
</form>
JavaScript
$( "#form1").submit(function( event ) {
if($('#pick').val()=='none'){
event.preventDefault(); //will prevent default form submission
alert("Please select one of the options provided");
return false;
}
});
You can check Demo on jsfiddle

jquery form only passing first select box values on submit

I'm new posting here, have visited several times over the years to read every ones ideas.
My issue is I have a form with 2 select boxes, second one populated with values upon selection in the first. The second holds a url value which you got to upon submit.
This function works perfectly using the onchange but on submit only the first of the second select list urls work. I can swap them but only the first works, all the others only pass the primary url followed by a crosshatch '#'.
<script>
$(document).ready(function($){
$("#category").change(function() {
$('select[name="product"]').removeAttr("name").hide();
$("#" + $(this).val()).show().attr("name", "product");
});
/* ' This works on all
$(".product").change(function() {
document.location = $(this).val();
});
*/
/* this only passes url on first product option list else passes opening url + #*/
$('#discover').submit(function() {
document.location = $(".product").val();
return false;
});
});
</script>

because $(".product").val(); will find first occurrence of DOM having class product so in any case it will fetch first one... u can do this using
$('#discover').submit(function() {
document.location = $('select[name="product"]').val();
return false;
});

Open Fiddler (fiddler2.com) and watch the post go past. I find that generally when more than one control on a page uses the same name, the browser actually passes all of them, but the server-side framework expecting each post parameter to be unique, ignores all but the last one.

when you submit , you have only one select box with attribute name ,so you can select the selected value by that attribute
$('#discover').submit(function() {
document.location = $('select[name="product"]').val();
return false;
});
