I have a form in "jQuery Dialog Box" and in which there is a <textarea> and the other is a pair of <input type="radio" /> buttons
Both are required fields and if the user leaves the testarea empty or do not check any of the radio , the user should get the message and the Dialog box should not close.
I have tried doing the validation, its working for Textarea but not for the radio buttons.
Here is the Fiddle I created : http://jsfiddle.net/JLDf5/
Here is the code for the same:
HTML
<div id="sessionReason" title="End Transaction">
<p class="validation-summary-errors marginBottom10">Provide the following information to proceed:</p>
<div class="marginBottom" id="sessionDocumentMessage">
<label class="marginBottom5 marginTop10">Return the document?</label>
<br>
<label>
<input type="radio" name="sessionDocuments" />Return</label>
<br>
<label>
<input type="radio" name="sessionDocuments" />Keep</label>
<br>
</div>
<p class="marginBottom5" id="sessionReasonMessage">Reason for ending the transaction:</p>
<textarea id="sessionReasonBox" class="reasonBox"></textarea>
</div>
jQuery
$('#sessionReason .validation-summary-errors').hide();
$("#sessionReason").dialog({
buttons: {
"End Transaction": function () {
var sessionReasonBox = $("#sessionReasonBox").val();
if ($('[name="sessionDocuments"]').is(':checked')){
$('#sessionReason .validation-summary-errors').show();
$("#sessionDocumentMessage label").addClass("redtext");
}
if (sessionReasonBox == "") {
$('#sessionReason .validation-summary-errors').show();
$("#sessionReasonMessage").addClass("redtext");
return false;
}
else {
$('#sessionReason .validation-summary-errors').hide();
$("#sessionReasonMessage").removeClass("redtext");
}
$(this).dialog("close");
},
"Cancel": function () {
$(this).dialog("close");
}
}
});
Please suggest!
IF blocks needs ELSE IF and the close should be inside the IF block. and check for ! (not) radio checked. and no need return false.
if (!$('[name="sessionDocuments"]').is(':checked')){
$('#sessionReason .validation-summary-errors').show();
$("#sessionDocumentMessage label").addClass("redtext");
}
else if (sessionReasonBox == "") {
$('#sessionReason .validation-summary-errors').show();
$("#sessionReasonMessage").addClass("redtext");
//return false;
}
else {
$('#sessionReason .validation-summary-errors').hide();
$("#sessionReasonMessage").removeClass("redtext");
$(this).dialog("close");
}

I'm implemented the code taken from here to check if radio button is checked and if not, see a warning message.
My code works, but I have a button for submit with ajax (jQuery(function($)) that go ahead also if radio input is not checked.
Some idea to avoid to run function jQuery if function validateForm() is validated?
Here my code:
document.getElementById("filter").onsubmit = validateForm;
function validateForm() {
var validConsumo = validateConsumo();
//if all fields validate go to next page
return validConsumo;
}
function validateConsumo() {
var select = document.getElementById("filter").select,
errorSpan = document.getElementById("error_select"),
isChecked = false,
i;
errorSpan.innerHTML = "";
for (i = 0; i < select.length; i += 1) {
if (select[i].checked) {
isChecked = true;
break;
}
}
if (!isChecked) {
errorSpan.innerHTML = "* You must pick a value";
return false;
}
return true;
}
jQuery(function($) {
$('#filter').submit(function() {
var filter = $('#filter');
$.ajax({
url: filter.attr('action'),
data: filter.serialize(), // form data
type: filter.attr('method'), // POST
beforeSend: function(xhr) {
filter.find('button').text('Filtering...'); // changing the button label
},
success: function(data) {
filter.find('button').text('Filter'); // changing the button label back
$('#response').html(data); // insert data
}
});
return false;
});
});

This is code for a button, but when it is checked it should print "checked" but everytime I press it, it logs "not checked" no matter the status of the button. How do I fix this?
document.addEventListener('DOMContentLoaded', function() {
var checkbox = document.querySelector('#auto-admit .mdc-switch');
function isChecked() {
if (checkbox.checked ) {
// do this
console.log('Checked');
} else {
// do that
console.log('Not checked');
}
}
checkbox.addEventListener('change', function() {
isChecked();
});
isChecked();
}
);
<div id="auto-admit">
<div class="mdc-switch">
<div class="mdc-switch__track"></div>
<div class="mdc-switch__thumb-underlay">
<div class="mdc-switch__thumb"></div>
<input
type="checkbox"
id="autoadmit-switch"
class="mdc-switch__native-control"
role="switch"
aria-checked="false"
/>
</div>
</div>
<label
id="autoadmit-switch-label"
class="mdc-button switch-label"
for="autoadmit-switch"
>Auto admit</label
>
</div>
You are trying to get the div container, rather than input.
var checkbox = document.querySelector('#auto-admit .mdc-switch__native-control');
document.addEventListener('DOMContentLoaded', function() {
var checkbox = document.querySelector('#auto-admit .mdc-switch__native-control');
function isChecked() {
if (checkbox.checked ) {
// do this
console.log('Checked');
} else {
// do that
console.log('Not checked');
}
}
checkbox.addEventListener('change', function() {
isChecked();
});
isChecked();
}
);
<div id="auto-admit">
<div class="mdc-switch">
<div class="mdc-switch__track"></div>
<div class="mdc-switch__thumb-underlay">
<div class="mdc-switch__thumb"></div>
<input
type="checkbox"
id="autoadmit-switch"
class="mdc-switch__native-control"
role="switch"
aria-checked="false"
/>
</div>

I just need a little help with this code.
var prv3;
var markIt3 = function(e) {
if (prv3 === this && this.checked) {
this.checked = false;
prv3 = null;
} else {
prv3 = this;
}
};
$(function() {
$('input.class_x').on('click', markIt3);
});
$('input[type=radio]').on('change', function() {
var current = $('input.class_x').filter(':checked');
var sbmtBtn = document.getElementById('SubmitButton');
sbmtBtn.disabled = true;
if (current.length > 1) {
sbmtBtn.disabled = false;
} else {
sbmtBtn.disabled = true;
}
}).change();
My request is the following:
can anybody just FIX what is missing in order for the form Submit button to go back to be disabled as it is supposed to be, because this form only enables it when 2 input type radio have been checked?
This form previous description is the main idea of everything:
A form, with several input type radios. Check at least 2 and the Submit button enables. But if you uncheck any of them, the Submit button should disable back, but I cannot manage to achieve this PART.
I just need a little HELP with IT, nothing else.
Please, DON'T change my code too much!Can it be done?
Check the fiddle right here: https://jsfiddle.net/Suiberu/70tkgk5t/13/
Thanks!
Actually problem is deselecting radio button not detected as a change. How about this
var prv3;
var markIt3 = function(e) {
if (prv3 === this && this.checked) {
this.checked = false;
prv3 = null;
} else {
prv3 = this;
}
checkIfValid();
};
$(function() {
$('input.class_x').on('click', markIt3);
});
function checkIfValid() {
var current = $('input.class_x').filter(':checked');
var sbmtBtn = document.getElementById('SubmitButton');
sbmtBtn.disabled = true;
if (current.length > 1) {
sbmtBtn.disabled = false;
} else {
sbmtBtn.disabled = true;
}
};
input {
display: block;
margin: 0.5em 0;
}
input[type='submit']:disabled {
color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form name="myform" autocomplete="off" method="post">
<input class="class_x" type="radio" name="name_1" value="value_1" id="id_1" />
<input class="class_x" type="radio" name="name_2" value="value_2" id="id_2" />
<input class="class_x" type="radio" name="name_3" value="value_3" id="id_3" />
<input type="submit" name="name_submit" value="OK" class="class_submit" id="SubmitButton" required/>
</form>
Or you can change the type of your inputs to checkBoxes and it will simply do the magic.
Here is the JSFiddle link.
var prv3;
var markIt3 = function (e) {
if (prv3 === this && this.checked) {
this.checked = false;
prv3 = null;
} else {
prv3 = this;
}
};
$(function () {
$('input.class_x').on('click', markIt3);
});
$('input[type=checkbox]').on('change', function () {
var current = $('input.class_x').filter(':checked');
var sbmtBtn = document.getElementById('SubmitButton');
sbmtBtn.disabled=true;
if (current.length > 1) {
sbmtBtn.disabled = false;
} else {
sbmtBtn.disabled = true;
}
}).change();
input {
display: block;
margin: 0.5em 0;
}
input[type='submit']:disabled {
color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form name="myform" autocomplete="off" method="post">
<input class="class_x" type="checkbox" name="name_1" value="value_1" id="id_1" />
<input class="class_x" type="checkbox" name="name_2" value="value_2" id="id_2" />
<input class="class_x" type="checkbox" name="name_3" value="value_3" id="id_3" />
<input type="submit" name="name_submit" value="OK" class="class_submit" id="SubmitButton" required />
</form>
Only the type has been changed from radio button to checkbox.
this.checked = false
..does not fire the change event, so the change code doesn't get fired when a radio button is unchecked.
Add the following line of code after that line:
$(this).change();
That will fire the change code.
Try using .prop() function instead
$('input[type=radio]').on('change', function() {
var current = $('input.class_x').filter(':checked');
var $sbmtBtn = $('#SubmitButton');
$sbmtBtn.prop('disabled', true);
if (current.length > 1) {
$sbmtBtn.prop('disabled', false);
} else {
$sbmtBtn.prop('disabled', true);
}
}).change();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<input type="radio" class="class_x">
<input type="radio" class="class_x">
<input id="SubmitButton" type="submit">
</form>
.prop() documentation
I'm trying to disable the submit button until all inputs have some data. Right now the button is disabled, but it stays disabled after all inputs are filled in. What am I doing wrong?
$(document).ready(function (){
validate();
$('input').on('keyup', validate);
});
function validate(){
if ($('input').val().length > 0) {
$("input[type=submit]").prop("disabled", false);
} else {
$("input[type=submit]").prop("disabled", true);
}
}
Here's a modification of your code that checks all the <input> fields, instead of just the first one.
$(document).ready(function() {
validate();
$('input').on('keyup', validate);
});
function validate() {
var inputsWithValues = 0;
// get all input fields except for type='submit'
var myInputs = $("input:not([type='submit'])");
myInputs.each(function(e) {
// if it has a value, increment the counter
if ($(this).val()) {
inputsWithValues += 1;
}
});
if (inputsWithValues == myInputs.length) {
$("input[type=submit]").prop("disabled", false);
} else {
$("input[type=submit]").prop("disabled", true);
}
}

Vanilla JS Solution.
In question selected JavaScript tag.
HTML Form:

var form = document.querySelector('form')
var inputs = document.querySelectorAll('input')
var required_inputs = document.querySelectorAll('input[required]')
var register = document.querySelector('input[type="submit"]')
form.addEventListener('keyup', function(e) {
var disabled = false
inputs.forEach(function(input, index) {
if (input.value === '' || !input.value.replace(/\s/g, '').length) {
disabled = true
}
})
if (disabled) {
register.setAttribute('disabled', 'disabled')
} else {
register.removeAttribute('disabled')
}
})
Some explanation:
In this code we add keyup event on html form and on every keypress check all input fields. If at least one input field we have are empty or contains only space characters then we assign the true value to disabled variable and disable submit button.
If you need to disable submit button until all required input fields are filled in - replace:
inputs.forEach(function(input, index) {
with:
required_inputs.forEach(function(input, index) {
where required_inputs is already declared array containing only required input fields.

You could try using jQuery Validate
http://jqueryvalidation.org/
<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.js"></script>
And then do something like the following:
$('#YourFormName').validate({
rules: {
InputName1: {
required: true
},
InputName2: { //etc..
required: true
}
}
});
Refer to the sample here.
In this only input of type="text" has been considered as described in your question.
HTML:
<div>
<form>
<div>
<label>
Name:
<input type="text" name="name">
</label>
</div>
<br>
<div>
<label>
Age:
<input type="text" name="age">
</label>
</div>
<br>
<div>
<input type="submit" value="Submit">
</div>
</form>
</div>
JS:
$(document).ready(function () {
validate();
$('input').on('keyup check', validate);
});
function validate() {
var input = $('input');
var isValid = false;
$.each(input, function (k, v) {
if (v.type != "submit") {
isValid = (k == 0) ?
v.value ? true : false : isValid && v.value ? true : false;
}
if (isValid) {
$("input[type=submit]").prop("disabled", false);
} else {
$("input[type=submit]").prop("disabled", true);
}
});
}
Try to modify your function like this :
function validate(){
if ($('input').val() != '') {
$("input[type=submit]").prop("disabled", false);
} else {
$("input[type=submit]").prop("disabled", true);
}
}
and place some event trigger or something like onkeyup in jquery.But for plain js, it looks like this :
<input type = "text" name = "test" id = "test" onkeyup = "validate();">
Not so sure of this but it might help.
Here is a dynamic code that check all inputs to have data when wants to submit it:
$("form").submit(function(e) {
var error = 0;
$('input').removeClass('error');
$('.require').each(function(index) {
if ($(this).val() == '' || $(this).val() == ' ') {
$(this).addClass('error');
error++;
}
});
if (error > 0) {
//Means if has error:
e.preventDefault();
return false;
} else {
return true;
}
});
.error {
border: 1px solid red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<form>
<form action="google.com">
<input type="text" placeholder="This is input #1" class="require" />
<input type="text" placeholder="This is input #2" class="require" />
<input type="submit" value="submit" />
</form>
</form>
Now you see there is a class called require, you just need to give this class to inputs that have to have value then this function will check if that input has value or not, and if those required inputs are empty Jquery will prevent to submit the form!
Modify your code
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js" type="text/javascript"></script>
<input type="text"><br>
<input type="text"><br>
<input type="text"><br>

validate();
$('input').on('keyup', validate);
});
function validate(){
$("input[type=text]").each(function(){
if($(this).val().length > 0)
{
$("input[type=submit]").prop("disabled", false);
}
else
{
$("input[type=submit]").prop("disabled", true);
}
});
}
</script>

This is my simple code which I have been working to just show valid or invalid if the wrong text is inserted but the problem I’m having is that when I hit enter the valid and invalid flashes without staying on screen.
Here is my Fiddle
function validate ()
{
var me = document.getElementById("my").value;
if (me == 'my')
{
document.getElementById("Result").innerHTML = "valid";
document.getElementById("Result").style.color = "green";
}
else
{
document.getElementById("Result").innerHTML = "invalid";
document.getElementById("Result").style.color = "red";
}
}
<form>
<button type="button" onclick ="yes" class="fa fa-search"></button>
<input type="text" id="my" onchange="validate()"></input>
<label id="Result"></label>
</form>
What is the mistake i am doing and How can i fix this ?
The problem is that you have your code inside tag. You need to prevent form submission if you want to stay on the page.
I have not included CSS here!!
<div class="container">
<div id="nav">
<div id="search">
<form id="form1">
<button type="button" onclick ="yes" class="fa fa-search"></button>
<input type="text" id="my"></input>
<label id="Result"></label>
</form>
</div>
</div>
</div>
$(document).ready(function(){
$("#form1").submit(function(event){
if ( !validate()) {
alert("Error");
event.preventDefault();
return false;
}
});
});
function validate ()
{
var me = document.getElementById("my").value;
if (me == 'my')
{
document.getElementById("Result").innerHTML = "valid";
document.getElementById("Result").style.color = "green";
return true;
}
else
{
document.getElementById("Result").innerHTML = "invalid";
document.getElementById("Result").style.color = "red";
return false;
}
}
Here is a fiddle. Hope it will help.
