I am using a very easy (but functional for my needs) Javascript script to validate input fields.
Here my main code:
<script language = "javascript">
function manage(txt) {
var bt = document.getElementById('send');
if (txt.value && txt2.value && txt3.value != '') {
bt.disabled = false;
}
else {
bt.disabled = true;
}
}
</script>
Here are my fields
<input type="text" name="FNAME" id="txt" class="input" size="20" placeholder="First Name *" onkeyup="manage(this)">
<input type="text" name="LNAME" id="txt2" class="input" size="20" placeholder="Last Name *" onkeyup="manage(this)">
<input type="text" name="EMAIL" id="txt3" class="input" size="20" placeholder="Email *" onkeyup="manage(this)">
and here my Submit button:
<input type="submit" name="submit" id="send" class="button button-primary" value="Subscribe" disabled>
What this does is to leave the submit button disabled until all fields have some value entered and works absolutely fine, however I also have a new and additional select option being:
<select name="Countries">
<option value="">Select Country</option>
<option value="Afghanistan">Afghanistan</option>
<option value="Åland Islands">Åland Islands</option>
<option value="Albania">Albania</option>
......
</select>
I've tried to apply the following changes:
<script language = "javascript">
function manage(txt) {
var bt = document.getElementById('send');
if (txt.value && txt2.value && txt3.value && txt4.value != '') {
bt.disabled = false;
}
else {
bt.disabled = true;
}
}
</script>
<select name="Countries" id="txt4" onkeyup="manage(this)">
<option value="">Select Country</option>
<option value="Afghanistan">Afghanistan</option>
<option value="Åland Islands">Åland Islands</option>
<option value="Albania">Albania</option>
......
</select>
However it does not seem to work. Some expert advise would be greatly appreciated. Thank you very much.
The proper form is
if (txt.value!='' && txt2.value!='' && txt3.value!='' && txt4.value!='')
You don't want to set the onkyeup event, but onchange. More universal event is oninput.
You should also check the required form elements tag attribute, which can provide you similar functionality without javascript. See here.
First of all, listening keyup event on your select will work only in case if select was changed by the keyboard. In case if it was changed by mouse, your event won't be fired. Better to listen onchange
On another hand, you should check the emptiness of all text fields, as you do for txt4.value!='':
if (txt.value!='' && txt2.value!='' && txt3.value!='' && txt4.value!='') {
...
}
Now it will work.
function manage(txt) {
var bt = document.getElementById('send');
if ( txt.value != '' && txt2.value != '' && txt3.value != '' && txt4.value != '' ) {
bt.disabled = false;
}
else {
bt.disabled = true;
}
}
<input type="text" name="FNAME" id="txt" class="input" size="20" placeholder="First Name *" onkeyup="manage(this)">
<input type="text" name="LNAME" id="txt2" class="input" size="20" placeholder="Last Name *" onkeyup="manage(this)">
<input type="text" name="EMAIL" id="txt3" class="input" size="20" placeholder="Email *" onkeyup="manage(this)">
<select name="Countries" id="txt4" onchange="manage(this)">
<option value="">Select Country</option>
<option value="Afghanistan">Afghanistan</option>
<option value="Åland Islands">Åland Islands</option>
<option value="Albania">Albania</option>
</select>
<input type="submit" name="submit" id="send" class="button button-primary" value="Subscribe" disabled>
I have done this type of functionality before. So I'm sharing my code here.
HTML Code
<form method="Post" class="form">
<input type="text" name="FNAME" id="txt" class="input" size="20" placeholder="First Name *" onblur="manage(this)">
<input type="text" name="LNAME" id="txt2" class="input" size="20" placeholder="Last Name *" onblur="manage(this)">
<input type="text" name="EMAIL" id="txt3" class="input" size="20" placeholder="Email *" onblur="manage(this)">
<select name="Countries" id="txt4" onchange="manage(this)" class="input">
<option value="">Select Country</option>
<option value="Afghanistan">Afghanistan</option>
<option value="Åland Islands">Åland Islands</option>
<option value="Albania">Albania</option>
</select>
<input type="submit" name="submit" id="send" class="button button-primary" value="Subscribe" disabled>
</form>
Javascript Code:
<script>
function manage($e){
var input = document.getElementsByClassName("input");
var status=false;
for(var i=0;i<input.length;i++){
if(input[i].value.trim()!='' && input[i].value.trim()!=null && input[i].value.trim()!=undefined){
status = true;
} else {
status = false;
break;
}
}
console.log(status);
if(status===true){
var email = document.getElementById("txt3").value;
if(!(/^([a-zA-Z0-9_.+-])+\#(([a-zA-Z0-9-])+\.)+([a-zA-Z0-9]{2,4})+$/.test(email.trim()))){console.log('1');
document.getElementById('send').disabled = true;
} else {console.log('2');
document.getElementById('send').disabled = false;
}
} else {
document.getElementById('send').disabled = true;
}
}
</script>
There are many ways to resolve this type of functionality but for this case, I have used the above code to achieve the goal. If you have any queries, please let me know. Thanks.

I have few fields on this code snippet. Here I have radio button If Field_One is checked show mentioned input field (country select, first name, last name, mobile, email, trans id) same like if Field_Two is checked show mentioned field (reference no, id no and trans id)
Here Trans ID. First Name, Last Name is mandotory for both radio button and its a required field. But I have added few required field without last name.
And Field_Two radio field will show field like reference id and id no. I want if only one field is required field and if only one field is filled up then its ok from both reference id and id no.
But My code is not working properly See the below snippet
One thing if First Country is Africa then show another Dropdown box with Country2 but its also required when Africa is selected but Africa not selected its not required.

Im trying to get this code to run with only plain JS.
When the user selects 'Other' I want my input field to show but only when they select 'Other'.
Ive hidden the input so its not displayed before its called.
I set a listener on the select field
Created the if/else statement looking for the value of the select field and set that to the value of other.
What am I missing here?
const select = document.getElementById('title');
let textField = document.getElementById('other-title').style.display = "none";
//This sets the focus on the first input field
function setFocusToTextBox(){
document.getElementById("name").focus();
}
setFocusToTextBox();
select.addEventListener("change", function() {
if(select.value === 'other') {
textField.style.display = "block";
} else {
textField.style.display = "none";
}
});
<fieldset>
<legend>Basic Info</legend>
<label for="name">Name:</label>
<input type="text" id="name" name="user-name" placeholder="Enter Your Full Name">
<label for="mail">Email:</label>
<input type="email" id="mail" name="user-email" placeholder="Enter Valid Email">
<label for="title">Job Role</label>
<select id="title" name="user-title">
<option value="full-stack js developer">Full Stack JavaScript Developer</option>
<option value="front-end developer">Front End Developer</option>
<option value="back-end developer">Back End Developer</option>
<option value="designer">Designer</option>
<option value="student">Student</option>
<option value="other">Other</option>
</select>
<label for="other-title">Other Title</label>
<input type="text" id="other-title" name="job_role_other" placeholder="Your Job Role">
</fieldset>
The problem is here:
let textField = document.getElementById('other-title').style.display = "none"
You are assigning textField string value "none".
Do this instead:
let textField = document.getElementById('other-title');
document.getElementById('other-title').style.display = "none";
This works:
const select = document.getElementById('title');
var textField = document.getElementById('other-title');
var otherTitleLabel = document.getElementById('other-title-label');
//This sets the focus on the first input field
document.getElementById('other-title').style.display = "none";
otherTitleLabel.textContent="";
function setFocusToTextBox(){
document.getElementById("name").focus();
}
setFocusToTextBox();
select.addEventListener("change", function() {
if(select.value === 'other') {
textField.style.display = "block";
} else {
textField.style.display = "none";
otherTitleLabel.textContent="";
}
});

I have a textarea element that is not displayed. If the user selects "Other" option in the select element, the textarea should show, but it is not showing with the below code.
The following is my select element :
<select class="form-control" name="feed" id="feed" value="" style="width:540px">
<option selected="selected" disabled="true">Please select</option>
<!-- <option></option> -->
<option value="Excellent" id="Excellent"> All text is excellent</option>
<option value="Other" id="Other" onclick="showHide(this)"
>Other feedback (free text)</option
>
</select>
The following is my textarea element :
<div class="form-group">
<label for="fb_text"></label>
<textarea
class="form-control"
name="fb_text"
id="fb_text"
rows="5"
placeholder="Describe yourself here..."
value=""
style="width:540px;display:none"
></textarea>
</div>
The following is my JS :
function showHide(elm) {
var Fbtext = document.getElementById("fb_text");
if (document.getElementById("feed").value == "Other") {
Fbtext.classList.remove("hide");
}
}
You can pass value from select using onchangeevent to your function and check if that value is equals to Others if yes display textarea else hide it. Working example :
function showHide(elm) {
if (elm == "Other") {
//display textbox
document.getElementById('fb_text').style.display = "block";
} else {
//hide textbox
document.getElementById('fb_text').style.display = "none";
}
}
<select class="form-control" name="feed" id="feed" value="" onchange="showHide(this.value)" style="width:540px">
<option selected="selected" disabled="true">Please select</option>
<!-- <option></option> -->
<option value="Excellent" id="Excellent"> All text is excellent</option>
<option value="Other" id="Other">Other feedback (free text)</option>
</select>
<div class="form-group">
<label for="fb_text"></label>
<textarea class="form-control" name="fb_text" id="fb_text" rows="5" placeholder="Describe yourself here..." value="" style="width:540px;display:none"></textarea>
</div>
Add change event to the select element, see if the selected option is 'Other', hide the text area else show.
const textareaEle = document.querySelector('textarea');
document.querySelector('select').addEventListener('change', function() {
textareaEle.style.display = (this.value == 'Other') ? 'block' : 'none';
});
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
<select class="form-control" name="feed" id="feed" value="" style="width:540px">
<option selected="selected" disabled="true">Please select</option>
<!-- <option></option> -->
<option value="Excellent" id="Excellent"> All text is excellent</option>
<option value="Other" id="Other">Other feedback (free text)</option>
</select>
<div class="form-group">
<label for="fb_text"></label>
<textarea class="form-control hide" name="fb_text" id="fb_text" rows="5" placeholder="Describe yourself here..." value="" style="width:540px;"></textarea>
</div>
I have not checked but I understand in your code you try to remove a class (hide) that you have not assigned, because you hide the textarea with the attribute style
Please try this example, I understand in your example you use bootstrap, for demonstration I have added hide
const feed = document.querySelector('#feed');
const fbtext = document.querySelector('#fb_text');
feed.addEventListener('change', handleChange);
function handleChange(event) {
const value = event.target.value;
if (value === 'Other') {
fbtext.classList.remove('hide');
return false;
}
fbtext.classList.add('hide');
}
.hide {
display: none;
}
<select
class="form-control"
name="feed"
id="feed"
value=""
style="width:540px"
>
<option selected="selected" disabled="true">Please select</option>
<option value="Excellent" id="Excellent"> Excellent</option>
<option value="Other" id="Other">Other</option>
</select>
<div class="form-group">
<label for="fb_text"></label>
<textarea
class="form-control hide"
name="fb_text"
id="fb_text"
rows="5"
placeholder="Describe yourself here..."
></textarea>
</div>
I have a basic form with some input fields and a dropdown(select field).
Almost all fields have a form of validation. When a field has an error, an error message with the CSS class 'errorText' is displayed next to the field.
By default, my submit button is 'disabled'. I want to remove the 'disabled' attribute from my submit button once all tags with 'errorText' CSS classes are hidden/removed.
my current script just hides all tags with 'errorText' when an error occurs. how do I stop it from doing that and how can I enable my submit button once all fields have been properly enter/validated? Thanks.
EDIT: SOLVED. CODE UPDATED.
// Field Validations
$('#firstName')
.on('blur', function() {
var $this = $(this);
if ($this.val() == '') {
$('label[for="firstName"]').addClass('errorText');
$('#errorFName').show();
} else {
$('label[for="firstName"]').removeClass('errorText');
$('#errorFName').hide();
}
});
$('#lastName')
.on('blur', function() {
var $this = $(this);
if ($this.val() == '') {
$('label[for="lastName"]').addClass('errorText');
$('#errorLName').show();
} else {
$('label[for="lastName"]').removeClass('errorText');
$('#errorLName').hide();
}
});
$('#state')
.on('blur', function() {
var $this = $(this);
if ($('#state').val() == "") {
$('label[for="state"]').addClass('errorText');
$('#errorState').show();
} else {
$('label[for="state"]').removeClass('errorText');
$('#errorState').hide();
}
});
// Submit Button validation
$('input, select').on('keyup, blur', function() {
if ($('.errorText:visible').length ||
$('#firstName' || '#lastName' || '#state').val() == '' ) {
$('input[type="submit"]').prop('disabled', true);
} else if ($('#firstName').val() != '' &&

$('#state').val() != '' ) {
$('input[type="submit"]').prop('disabled', false);
}

If it helps, check this update using data-attribute. We group the label,input,error in a div and handle error message. Also simplified the check valid on input and select element but can be modified.

So I'm trying to change a select box's style if the value is not changed ie. the user has not selected anything. That yesnoCheck is a function which shows an additional input field if the choice "other" is selected. I don't think it affects this form validation though. This same kind of validation works fine with an input field but it won't work with a select box.
I've also treid selectedIndex == 0 but it doesn't work either.
HTML:
<form name="myForm" method="post" action="" onsubmit="return(validate());">
<label for="lastname">Sukunimesi:</label>
<input type="text" id="lastname" name="lastname" /><br />
<select id="car" name="car" onchange="javascript:yesnoCheck()">
<option id="noCheck" value="none">Valitse automerkkisi</option>
<option id="noCheck" value="1">Lada</option>
<option id="noCheck" value="2">Mosse</option>
<option id="noCheck" value="3">Volga</option>
<option id="noCheck" value="4">Vartburg</option>
<option id="yesCheck" value="other">Muu</option>
</select>
<input type="submit" value="Submit" />
</form>
JS:
<script type="text/javascript">
function yesnoCheck() {
if (document.getElementById("yesCheck").selected) {
document.getElementById("ifYes").style.display = "block";
}
else document.getElementById("ifYes").style.display = "none";
}
function validate() {
if (document.myForm.lastname.value.length < 3) {
document.getElementById("lastname").className = "required";
return false;
}
if (document.myForm.car.value == "none") {
document.getElementById("car").className = "required";
return false;
}
alert ("Everything is fine!");
}
</script>
Your code works check your form name and make sure your form exists before the script is run.
function check(){
if (document.myForm.car.value == "none") {
document.getElementById("car").style.border = "1px solid #900";
document.getElementById("car").style.backgroundColor = "#ff9";
return false;
}
}
<form name="myForm">
<select id="car" name="car" onchange="javascript:yesnoCheck()">
<option id="noCheck" value="none">Valitse automerkkisi</option>
<option id="noCheck" value="1">Lada</option>
<option id="noCheck" value="2">Mosse</option>
<option id="noCheck" value="3">Volga</option>
<option id="noCheck" value="4">Vartburg</option>
<option id="yesCheck" value="other">Muu</option>
</select>
</form>
<button onclick="check()">Run script</button>
So the solution was to delete return false; from the function.
