How to specify minlength in jquery?

How to specify minlength in jquery? - javascript

If the status value is completed then comment field is required is working good.But the problem is, I want to specify comment field is required for minimum of 50 character.
The Below code: index.php
<!-- Select Basic -->
<div class="form-group">
<label class="col-md-4 control-label" for="selectbasic">Status</label>
<div class="col-md-4">
<select id="status" name="status[]" class="form-control" >
<option value="Pending">Pending</option>
<option value="Work in process">Work in process</option>
<option value="Completed">Completed</option>
</select>
</div>
</div>
<!-- Text input-->
<div class="form-group">
<label class="col-md-4 control-label" for="textinput">Comment</label>
<div class="col-md-4">
<input id="commentss" name="comment[]" type="text" placeholder="" class="form-control input-md" />
</div>
</div>
<div class="col-md-8 col-sm-12 col-24">
<div class="input_fields" style="color:black">
<button class="add_field btn " onclick="incrementValue()" >Add More</button>
<div>
<input type="text" name="mytextt[]" hidden="" ></div>
</div>
</div>
Javascript
<script type="text/javascript">
$(document).ready(function () {
$("#status").click(function () {
if ($("#status").val() == "Completed") {
$("#commentss").attr("required", "required");
}
else
$("#commentss").attr("required", false);
});
});
</script>

Use length to find the length of the string
if($('#commentss').val().length < 50){
alert("Please enter 50 characters atleast");
} else {
//submit
}

For this please use below code :
<script type="text/javascript">
$(document).ready(function () {
$("#status").click(function () {
var commenttext = document.getElementById('commentss').value;
if (commenttext.length < 50)
{
alert("Please Enter minimum 50 character!")
}
else
{
//Add code
}
});
});
</script>

In Jquery ...
For Dynamic Tracking ...
(You can use blur or keyup even too.)
$(function() {
//disable submit if you want to
$('#commentss').on('input', function(e) {
if(this.value.length >= 50) {
//success
} else {
//fail?
}
});
});
To Validate on Click only ...

bootstrap 4 validation with password confirmation and submit disabled until form validated (Registration form)

In a simple form there are 3 input fields with regex pattern in each.
Two of them ('Password' and 'Confirm Password') must match. If the don't, a message "Not Matching" is displayed. If they do, "Valid" is displayed.
How can I (via the javascript) force the Bootstrap 4 validation's red border and 'X' icon to be displayed in the following case :
Entering 'aa' in the 'Password' field (it matches the regex hence the valid green border and V icon).
Entering 'aa' in the 'Confirm Password' field (it matches the regex hence the valid green border and V icon).
Now I add another character to 'Confirm Password' and it immediately displays "Not Matching", but since it's ok according to the regex - it is still green with a 'V' icon.
I need to force the red border and 'X' icon when this happens.

Couldn't you toggle the is-invalid class as needed on both password inputs?

Demo: https://www.codeply.com/p/AQBzIBAsZl

With help from #Zim I got started and managed to solve it.
Following is the code for a full Registration form with comparison of the 2 passwords.
Notice that the Submit button is enabled ONLY when all elements in the form are valid!
Note 1 : I tested it extensively but it might have a bug or a design flaw (please let us all know about it if you find one).
Note 2 : When it comes to Javascript and JQuery, I was born a mere 2 weeks ago, so I guess my solution is not as elegant as can possibly be (again, let us all know if you can improve it).

issue in Bootstrap 4 validation on select field

I'm new to jQuery and Bootstrap, I'm using jquery and Bootstrap 4 for validation of my form modal, whenever there is an error it must show the error below the corresponding fields, but in my case the select field gets overwritten by the error and select field disappears but it works fine for input field.
here have a look and if you want to have a close look on image just click on it..
As you can see the select fields get overwritten by the fieldError but it's fine for input field.
here's my jQuery validation code:
$(function(){
setCategorySelect();
$(document).on('shown.bs.modal','#manageItemsModal', function () {
$('#manageItemsModal #btnSubmit').on('click', function(){
if (validateForm()) {
messageSuccess("Very well");
} else {
messageError("Oops!!");
}
});
});
});
function validateForm() {
var validationStatus = true;
if ($('#manageItemsForm #selectedCategory').val().length == 0) {
showFieldError(('#manageItemsForm #selectedCategory'), 'Must not be blank');
if (validationStatus) { $('#manageItemsForm #selectedCategory').focus() };
validationStatus = false;
}
if ($('#manageItemsForm #selectedBrandModel').val().length == 0) {
showFieldError(('#manageItemsForm #selectedBrandModel'), 'Must not be blank');
if (validationStatus) { $('#manageItemsForm #selectedBrandModel').focus() };
validationStatus = false;
}
if ($('#manageItemsForm #serialNo').val().length == 0) {
showFieldError(('#manageItemsForm #serialNo'), 'Must not be blank');
if (validationStatus) { $('#manageItemsForm #serialNo').focus() };
validationStatus = false;
}
if ($('#manageItemsForm #selectedVendor').val().length == 0) {
showFieldError(('#manageItemsForm #selectedVendor'), 'Must not be blank');
if (validationStatus) { $('#manageItemsForm #selectedVendor').focus() };
validationStatus = false;
}
if ($('#manageItemsForm #selectedBranch').val().length == 0) {
showFieldError(('#manageItemsForm #selectedBranch'), 'Must not be blank');
if (validationStatus) { $('#manageItemsForm #selectedBranch').focus() };
validationStatus = false;
}
return validationStatus;
}
function showFieldError(element, message) {
$(element).addClass('is-invalid');
$(element).next().html(message);
$(element).next().show();
}
function clearFieldError(element) {
$(element).removeClass('is-invalid');
$(element).removeAttr('required');
$(element).next().html('');
}
function setCategorySelect() {
var $categorySelect = $('#manageItemsForm #selectedCategory').selectize({
selectOnTab: true,
closeAfterSelect: true,
persist: false,
create: false,
valueField: 'id',
labelField: 'text',
options: [],
preload: true,
onInitialize : function() {
var self = this;
$.ajax({
url: '/assetCategory/search',
type: 'POST',
dataType: 'json',
data: {
searchText: '*'
},
error: function() {
callback();
},
success: function(res) {
self.addOption(res.data);
}
});
},
load: function(query, callback) {
if (query.length <= 2) return callback();
$.ajax({
url: '/assetCategory/search',
type: 'POST',
dataType: 'json',
data: {
searchText: query + "*"
},
error: function() {
callback();
},
success: function(res) {
console.log(res.data);
callback(res.data);
$categorySelect.refreshItems();
},
fail : function() {
callback();

By the way I am using jQuery in Spring boot and everything is working fine(save, update, delete) except for validation from jQuery.
Please help!!

I can't see working code because you using some external references like selectize.
I suggest you get used to "snippets" to provide code.
Bytheway, your problem seems to be just about styles. I can't know, but my bet is you just need to provide a css style for
.select::after.error {
color:red;
}
You can inspect and copy CSS code.

The problem is in Your HTML, the nodes of your .input-group does not have allways the same structure. In some cases you have .invalid-feedback just after the input such as this HTML
<div class="form-group">
<label for="serialNo" class="col-form-label"><span class="text-danger">*
</span>Serial No.</label>
<input type="text" class="form-control" id="serialNo" name="serialNo">
<div class="invalid-feedback"></div>
</div>
For other fields the .invalid-feedback isn't after the input but outside from .form-group. take a look
<div class="input-group date" data-date-format="dd-M-yyyy">
<input type="text" class="form-control" id="purchaseDate" name="purchaseDate" />
<span class="input-group-text input-group-append input-group-addon">
<i class="simple-icon-calendar"></i>
</span>
</div>
<div class="invalid-feedback"></div>
This difference in HTML structure of the form made your showFieldError() and clearFieldError() not working allways as you expected, because $(element).next() don't catch the right DOM node for insert/remove the validation message. So in some cases clearFieldError remove the wrong HTML tag and this can make your selects disappear
function showFieldError(element, message) {
$(element).addClass('is-invalid');
$(element).next().html(message);
$(element).next().show();
}
function clearFieldError(element) {
$(element).removeClass('is-invalid');
$(element).removeAttr('required');
$(element).next().html('');
}
So you have to fix Your HTML to obtain the same structure for all fields. Put the <div class="invalid-feedback"></div> allways just below the select or input field. Otherwise you have to change the selector that you pass to showFieldError() and clearFieldError() functions according to your HTML
Otherwise a simply approach is to add a ID to divs with class .invalid-feedback, an ID which you can easily manage by his related input ID, something like
<div class="input-group date" data-date-format="dd-M-yyyy">
<input type="text" class="form-control" id="purchaseDate" name="purchaseDate" />
<span class="input-group-text input-group-append input-group-addon">
<i class="simple-icon-calendar"></i>
</span>
</div>
<div id="purchaseDate_err_mex" class="invalid-feedback"></div>
in this way you can pass the input name to your functions and them becomes
function showFieldError(input_id, message) {
$('#'+input_id).addClass('is-invalid');
$('#'+ input_id +'_err_mex').html(message).show();
}
function clearFieldError(input_id) {
$('#'+input_id).removeClass('is-invalid');
//$('#'+input_id).removeAttr('required');
/* don't need to remove required attribute from mandatory fields */
$('#'+ input_name +'_err_mex').html('').hide();
}
and the validation function
function validateForm() {
var validationStatus = true;
if ($('#selectedCategory').val().length == 0) {
showFieldError('selectedCategory', 'Must not be blank');
if (validationStatus) { $('#selectedCategory').focus() };
validationStatus = false;
}
........
return validationStatus;
}
You only check if the length of all fields is more than 0, so you can validate the entire form within a loop
function validateForm() {
var validationStatus = true;
var form_inputs = $('#manageItemsForm input, #manageItemsForm select')
$.each(form_inputs,function(){
var input_id = $(this).attr('name');
clearFieldError(input_id);
if ($.trim($(this).val()).length == 0 && $(this).is("[required]")) {
showFieldError(input_id, 'Must not be blank');
if (validationStatus) { $('#'+input_id).focus() };
validationStatus = false;
}
});
return validationStatus;
}

Submit form not working when using jQuery

I have a form and when the user clicks submit, I would like the form to hide and a thank you message to appear. Unfortunately with the code I have, it's not working and I can't figure out why. I think it might be something with the jQuery so I'd like to try and re-write this function using vanilla JS, but I'm not sure how.
It is the last part of the function, the if (empty.length), hide form, show thank you message that is causing me problems. Everything else is working fine, so its this function I would like to try and write in JavaScript, or try another way using jquery to make it work. The problem is it doesn't work in my code, but when I open this in a jsfiddle, it doesnt just hide the form it opens a new page and I get an error. I don't want the user to be directed to a new page, I just want the form to close and thank-you message to appear. I am very new to this so I apologize if my code is messy.
UPDATE: I really think the issue here is the jQuery, can I write this in plain JS and would that fix it?
var $subscribe = $('#click-subscribe');
var $subscribeContent = $('#subscribe-content');
var $subscribeClose = $('#subscription-close');
$subscribeContent.hide();
$subscribe.on('click', function(e) {
e.preventDefault();
$subscribeContent.slideToggle();
});
$subscribeClose.on('click', function(e) {
e.preventDefault();
$subscribeContent.slideToggle();
})
var $form = $('#signup-form'),
$signupForm = $('.form-show'),
$formReplace = $('#thank-you');
$formReplace.hide();
$form.on('submit', function() {
var empty = $(this).find("input, select, textarea").filter(function() {
return this.value === "";
});
if (empty.length <= 0) {
$signupForm.hide();
$formReplace.show();
} else {
return false;
}
});

I think some other javascript/jQuery code are making issues to run the codes, for simple solution make your code as plugin and called it like following.
create new js file called validation.js
(function($){
$.fn.validation = function(){
var $subscribe = $('#click-subscribe');
var $subscribeContent = $('#subscribe-content');
var $subscribeClose = $('#subscription-close');
$subscribeContent.hide();
$subscribe.on('click', function(e) {
e.preventDefault();
$subscribeContent.slideToggle();
});
$subscribeClose.on('click', function(e) {
e.preventDefault();
$subscribeContent.slideToggle();
});
var $form = $('#signup-form'), $signupForm = $('.form-show'), $formReplace = $('#thank-you'); $formReplace.hide();
this.on('submit', function(e){
var empty = $(this).find("input, select, textarea").filter(function() {
return this.value === "";
});
if(empty.length == 0){
$signupForm.hide();
$formReplace.show();
}
e.preventDefault();
});
};
})(jQuery);
Now, call the validation.js at the head like below
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="validation.js"></script>
<script type="text/javascript">
$(function(){
$('#signup-form').validation();
});
</script>

ajax form is not working how it should

hello i been working on a form using ajax but when it comes down to validating a select box
problem 1) every time i leave the job_est value empty the form is still submitted as if it was validated
problem 2) can i use async in ajax
sorry for my writing skills
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>

You should change selectbox's name attribute with value

<option value="job">Job</option>
<option value="est">Estimation</option>
</select>
and in your javascript, it should be
if (job_est.val() == 'select') {
job_est.addClass('hightlight');
return false;
}

Validate form using jqueryvalidate.js and ckeditor Codeigniter

Hello. I have a form that gets validated by jqueryvalidate.js. I have a drop down menu and the menu will be different when I choose "Library Asset" because I need to choose another drop down menu that is hidden.
The problem is, when I am not choose other menu that is not showing another drop down menu..
the required rules still implemented.. so the form can't be submitted except the one that is showing another drop down menu..
Can someone help me here?
This is my code:
View(Js):
<script type="text/javascript">
function showbook()
{
var domObj1 = document.getElementById('emptybox');
var domObj2 = document.getElementById('showupbox');
if(domObj1.style.display =='none')
{
domObj1.style.display = 'block';
domObj2.style.display = 'none';
}
else
{
domObj1.style.display = 'none';
domObj2.style.display = 'block';
}
}
function closebook()
{
var domObj1 = document.getElementById('emptybox');
var domObj2 = document.getElementById('showupbox');
if(domObj1.style.display =='none')
{
domObj1.style.display = 'block';
domObj2.style.display = 'none';
}
}
function showhidebook()
{
console.log($('#CategoryAdviceSelect').val());
if($('#CategoryAdviceSelect').val() == 1)
{
showbook();
}
else{
closebook();
}
}
My validation rules:
<script>
$().ready(function() {
$("#feedback_form").validate({
ignore: "input:hidden:not(input:hidden.required)",
rules: {
CategoryAdviceSelect:"required",
Subject:"required",
Advice:"required",
BookSelect:"required"
},
messages: {
CategoryAdviceSelect:"Please select one of category advice",
Subject:"This field is required",
Advice:"This field is required",
BookSelect:"This field is required"
},
errorElement: "span",
highlight: function(element) {
$(element).parent().addClass("help-block");
},
unhighlight: function(element) {
$(element).parent().removeClass("help-block");
}
});
});
</script>
And my html view
<div class="row-fluid ">

Finally I can solve this..
<script>
$(document).ready(function() {
for(var name in CKEDITOR.instances) {
CKEDITOR.instances["Advice"].on("instanceReady", function() {
// Set keyup event
this.document.on("keyup", updateValue);
// Set paste event
this.document.on("paste", updateValue);
});
function updateValue() {
CKEDITOR.instances["Advice"].updateElement();
$('textarea').trigger('keyup');
}
}
$("#feedback_form").validate({
ignore: 'input:hidden:not(input:hidden.required)',
rules: {
CategoryAdviceSelect:"required",
Subject:"required",
Advice:"required",
BookSelect:{
required: function(element){
return $("#CategoryAdviceSelect").val()==1;
}
}
},
messages: {
CategoryAdviceSelect:"Please select one of category advice",
Subject:"This field is required",
Advice:"This field is required",
BookSelect:"This field is required",
},
errorElement: "span",
errorPlacement: function (error, element) {
if ($(element).attr('name') == 'Advice') {
$('#cke_Advice').after(error);
} else {
element.after(error);
}
},
highlight: function(element) {
$(element).parent().addClass("help-block");
},
unhighlight: function(element) {
$(element).parent().removeClass("help-block");
}
});
});
</script>
