I'm struggling with the following issue - I have an HTML form in which there are three select fields. Before submitting values, I want to make a form validation in which at least ONE of the four dropdowns should be selected. I have the following code but it keeps requiring all the dropdowns.
Link to the code: jsfiddle
Code - HTML
<div class="container">
<div class="row">
<div class="col-lg-12">
<form method="post" id="myform">
<div class="form-group ">
<label class="control-label " for="select">
Select a Choice
</label>
<select class="select form-control" id="select1" name="select1" required>
<option value="">---</option>
<option value="First Choice">1</option>
<option value="Second Choice">2</option>
<option value="Third Choice">3</option>
</select>
<select class="select form-control" id="select2" name="select2" required>
<option value="">---</option>
<option value="First Choice">a</option>
<option value="Second Choice">b</option>
<option value="Third Choice">c</option>
</select>
<select class="select form-control" id="select3" name="select3" required>
<option value="">---</option>
<option value="First Choice">X</option>
<option value="Second Choice">Y</option>
<option value="Third Choice">Z</option>
</select>
</div>
<div class="form-group">
<div>
<button class="btn btn-primary " name="submit" id="sub" type="submit">
Submit
</button>
</div>
</div>
</form>
</div>
</div>
</div>
Code - JS:
$(document).ready(function () {
$('#sub').click(function() {
check = $(".select option:selected").length;
if(!check) {
alert("You must select an option from at least one dropdown");
return false;
}
});
});
Where I make a mistake in the code?
Take a look at this
jsfiddle example
You need to remove the "required" attribute and manage required values using JS because if you set all combobox to required you'll be forced to fill all of them.
<div class="container">
<div class="row">
<div class="col-lg-12">
<form method="post" id="myform">
<div class="form-group ">
<label class="control-label " for="select">
Select a Choice
</label>
<select class="select form-control" id="select1" name="select1">
<option selected disabled value="">---</option>
<option value="First Choice">1</option>
<option value="Second Choice">2</option>
<option value="Third Choice">3</option>
</select>
<select class="select form-control" id="select2" name="select2">
<option selected disabled value="">---</option>
<option value="First Choice">a</option>
<option value="Second Choice">b</option>
<option value="Third Choice">c</option>
</select>
<select class="select form-control" id="select3" name="select3">
<option selected disabled value="">---</option>
<option value="First Choice">X</option>
<option value="Second Choice">Y</option>
<option value="Third Choice">Z</option>
</select>
</div>
<div class="form-group">
<div>
<button class="btn btn-primary " name="submit" id="sub" type="submit">
Submit
</button>
</div>
</div>
</form>
</div>
</div>
</div>
JS code
$(document).ready(function () {
$('#sub').click(function() {
check = $('option[disabled]:selected').length;
if(check == 3) {
alert("You must select an option from at least one dropdown");
return false;
}
});
});
Hope it helps you
First, you must delete the required on your select tags. Then, use something like this in the jquery part:
$(document).ready(function () {
$('#sub').click(function() {
var anySelected = false;
$(".select option:selected").each(function(){
if(!$(this).val() == ""){
anySelected = true;
}
});
if(!anySelected) {
alert("You must select an option from at least one dropdown");
return false;
}
});
});
Here is a working fiddle.
Hope it helps!

I'm trying to figure out how to show hidden div but I'm a little rusty on jQuery.
So when a user selects "Yes" from Menu1 dropdown, I want the Menu2 dropdown to show up. l'm using style="visibility: hidden; to hide Menu2.
<div class="form-row">
<div class="form-group col-md-4">
<label for="inputEmail4">Menu1</label>
<select class="form-control" name="name" id="Menu1">
<option value="">--Please choose an option--</option>
<option value="Yes">Yes</option>
<option value="No">No</option>
</select>
</div>
**<div class="form-group col-md-4" style="visibility: hidden;">**
<label for="inputPassword4">Menu2</label>
<select class="form-control" name="pets" id="Menu2">
<option value="">--Please choose an option--</option>
<option value="dog">Dog</option>
<option value="cat">Cat</option>
</select>
</div>
You can do it very easily in jQuery using the show and hide functions:
$("#Menu2Container").hide();
$("#Menu1").on("change", function(){
if ($(this).val()=="Yes")
$("#Menu2Container").show();
else
$("#Menu2Container").hide();
});
How this works:
First give a class or id to #Menu2's container so you can target it in your jQuery, e.g. <div id="Menu2Container">
Hide your Menu2 container in the jQuery when the page loads
Add an event handler for change events on #Menu1 to detect when an option is selected.
In the handler, get the value of the selected option using val()
If "Yes" is selected, show() the #Menu2Container, otherwise hide() it
Working Example:
$("#Menu2Container").hide();
$("#Menu1").on("change", function(){
if ($(this).val()=="Yes")
$("#Menu2Container").show();
else
$("#Menu2Container").hide();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="form-row">
<div class="form-group col-md-4">
<label for="inputEmail4">Menu1</label>
<select class="form-control" name="name" id="Menu1">
<option value="">--Please choose an option--</option>
<option value="Yes">Yes</option>
<option value="No">No</option>
</select>
</div>
<div class="form-group col-md-4" id="Menu2Container">
<label for="inputPassword4">Menu2</label>
<select class="form-control" name="pets" id="Menu2">
<option value="">--Please choose an option--</option>
<option value="dog">Dog</option>
<option value="cat">Cat</option>
</select>
</div>
Note: I would suggest considering if the grid col is the best container to hide for the menu - this obviously depends on your layout, but showing and hiding the col will affect the grid layout and could affect the overall appearance.
You can use this siple javascript code for that.
No need to go for jQuery here.
just give a id to hidden div so we can access it.
document.getElementById('Menu1').onchange = e => {
let hiddenElement = document.getElementById('hiddenDiv')
e.target.value == 'Yes' ?
hiddenElement.style.visibility = 'visible' :
hiddenElement.style.visibility = 'hidden'
}
<div class="form-group col-md-4">
<label for="inputEmail4">Menu1</label>
<select class="form-control" name="name" id="Menu1">
<option value="">--Please choose an option--</option>
<option value="Yes">Yes</option>
<option value="No">No</option>
</select>
</div>
**<div class="form-group col-md-4" id='hiddenDiv' style="visibility: hidden;">**
<label for="inputPassword4">Menu2</label>
<select class="form-control" name="pets" id="Menu2">
<option value="">--Please choose an option--</option>
<option value="dog">Dog</option>
<option value="cat">Cat</option>
</select>
</div>
Vanilla Javascript:
You can use an event listener to change the visibility to visible.
Set a conditional in your event handler and set the handler to change, check to see if the value of the target of your event listener is set to the desired value Yes, if it is, then set the div to visible...
I did add an ID to your DIV to target it directly...
let showMe = document.getElementById("showMe");
let menu1 = document.getElementById("Menu1");
menu1.addEventListener("change", function(e){
if(this.value === 'Yes'){
showMe.style.visibility = 'visible';
}
});
<div class="form-row">
<div class="form-group col-md-4">
<label for="inputEmail4">Menu1</label>
<select class="form-control" name="name" id="Menu1">
<option value="">--Please choose an option--</option>
<option value="Yes">Yes</option>
<option value="No">No</option>
</select>
</div>
**
<div id="showMe" class="form-group col-md-4" style="visibility: hidden;">**
<label for="inputPassword4">Menu2</label>
<select class="form-control" name="pets" id="Menu2">
<option value="">--Please choose an option--</option>
<option value="dog">Dog</option>
<option value="cat">Cat</option>
</select>
</div>
You can simply use ternary operator (short form of if and else)
Along with jQuery functions like => show() and hide() function to display your second menu2 when you select Yes
Just add this code in jQuery:
const $Menu2 = $("#Menu2Container") //element
$Menu2.hide(); //Initially hide
//Change function
$("#Menu1").on("change", function() {
$(this).val() == "Yes" ? $Menu2.show() : $Menu2.hide();
});
Live working demo:
const $Menu2 = $("#Menu2Container") //element
//Initially hide
$Menu2.hide();
//Chage function
$("#Menu1").on("change", function() {
$(this).val() == "Yes" ? $Menu2.show() : $Menu2.hide();
});

There is a wrong variable x, to be changed to c:

var s=document.getElementById("stage");
if(c.options[c.selectedIndex].text==""){
document.getElementById("course_err").innerHTML="You have to select a course";
}else if(s.options[s.selectedIndex].text==""){
document.getElementById("stage_err").innerHTML="You have to select a semester";

You will have to make couple of changes to your code to achieve your desired result.
You should not include the second select box initially in DOM if you want to show it only after user select a specific value.
You will have to add values to your select Options
You Class or Id to your select boxes
Use Jquery .on('change') function to accomplish your desired result
Use the below code for further reference.
var selectLevelTwo = '<div class="col-md-4 col-sm-4 select-level-two"><p>Branch<span class="astric">*</span></p><select class="Academic"><option value="" id="Select">Select</option><option value="" id="PCMB">PCMB</option><option value="" id="PCMC">PCMC</option><option value="" id="PCMS">PCMS</option></select></div>';
$(document).on('change', '.select-level-one', function(){
var firstSelectValue = $('.select-level-one option:selected').val();
if(firstSelectValue == 'science'){
$(this).parent().after(selectLevelTwo);
} else {
$('.select-level-two').fadeOut('fast');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

I'm wondering how I can chain an input box after chaining a selection in my form.
I'm using http://www.appelsiini.net/projects/chained to chain my selects and it works. However, I need to adjust this to also allow for the chaining of an input. In the below example it would be someone would choose an option such has an item has Strength on it then the select menu of value options then input the value. I'm trying to also incorporate into this where after those 3 options of item, controller, value are inputed the user has the option to filter more so another box appear with the same options of strength, agility, etc. http://jsfiddle.net/isherwood/XMx4Q/ is an example of work I used to incorporate this into my own work.
<form id="myform" name="myform" method="post" action="<?php echo $_SERVER['PHP_SELF'];?>">
<div>
<label for="searchterm">Name:</label>
<input type="text" name="searchterm">
</div>
<div>
<div class="chainedSelectFilter">
<select name="specificFilter" class="attribute">
<option value="" selected>Select a Filter</option>
<option value="strength">Has Strength</option>
<option value="agility">Has Agility</option>
<option value="spirit">Has Spirit</option>
<option value="stamina">Has Stamina</option>
</select>
<select name="specificFilter" class="valueController">
<option value=">" selected>></option>
<option value=">=">>=</option>
<option value="=">=</option>
<option value="<="><=</option>
<option value="<"><</option>
</select>
</div>
</div>
</div>
<div>
<label for="submit"></label>
<input type="submit" name="submit" value="Filter">
</div>
Code reference below shows how to accomplish this. Here is jsFiddle that shows it's working.
