Java script validation issues

I have a bug that I could not figure out in my validation method. I have a function that validate the "code" table in my database to make sure the user can not input duplicate data. It is all working as expected and here is the code:
function validateCode() {
$('#code-error').html('')
if ($('#code').val() != '') {
$.ajax({
url: '${createLink(action:'checkCode')}',
type: 'GET',
data: {
'code': $('#code').val(),
},
// dataType:'json',
success: function (data) {
if (data == 'true') {
$('#code-error').html('Code already exist')
$(':input[type="submit"]').prop('disabled', true);
} else {
// $('#code-error').html('Code not exist')
$(':input[type="submit"]').prop('disabled', false);
}
},
error: function (request, error) {
alert("Request: " + JSON.stringify(request));
}
});
}
}
But it is not stable.First the message and the button are disabled in the first couples of tried but if I continue to test it by re-enter the code that exist and the code that does not exist the button disabled however the error message is not showing under the input box.
Here is my html code :
<div class = "row" style = "margin-top:15px;">
<div class = "col-md-12">
<div class = "row">
<div class = "col-md-5 text-right" style = "font-weight: bold"><span class="placeholder">Code</span></div>
<div class = "col-md-7">
<div class="form-group">
<input style = "width: 50%"type="text" class="form-control" onkeyup="validateCode()" id="code" placeholder="Enter code" name="code">
<input type="hidden" name="current-code" id = "current-code">
<div class = "row">
<div id = "code-error" class = "col-md-12" style ="color:red"></div>
</div>
</div>
</div>
</div>
</div>
</div>
And here is my controller function for validating the code:
def checkCode() {
def allow
String compareCode = params?.code
def customer = Customer.findByCode(compareCode)
if (customer == null) {
allow = false //not exist
} else if (customer != null) {
allow = true //exist
}
render allow
}

jQuery validate , how to make validation rules for dynamically generated fields?

I have an HTML form with dynamically add more fields. For example company name. I am trying to use the jQuery validate method to validate. It is working fine with the existing company name field. Here is the code.
<script>
$("#company_creation_form").validate({
rules:{
company_name: {
required: true,
minlength: 3
}
},
submitHandler: function (form) {
$.ajax({
type: "POST",
url: "<?php echo BASE_URL;?>crm/thankyou/",
data: $(form).serialize()+"&company_count="+company_count,
success: function () {
alert("thanks");
}
});
return false; // required to block normal submit since you used ajax
}
});
</script>
When I click on add more button another company name field will create on the form. The below code is failed to validate the dynamically generated field. Here I am getting the field count globally in this variable company_count
<script>
$("#company_creation_form").validate({
rules:{
company_name: {
required: true,
minlength: 3
},
I tried like below, but this is giving me error
if(company_count> 0){
var new_field = jQuery("#company_name"+company_count);
new_field : {
required: true,
minlength: 3
},
}
The above block code is showing error in the text editor it self
},
submitHandler: function (form) {
$.ajax({
type: "POST",
url: "<?php echo BASE_URL;?>crm/thankyou/",
data: $(form).serialize()+"&company_count="+company_count,
success: function () {
alert("thanks");
}
});
return false; // required to block normal submit since you used ajax
}
});
</script>
Can anyone help me with how to make validation for these dynamically generated fields? Any help would be greatly appreciated. I am using form submission by using Ajax.
Code to add company fields dynamically
var company_room = 0;
var company_room1 = 0;
function add_another_company() {
company_room++;
company_room1++;
var objTo = document.getElementById('company_field')
var divtest = document.createElement("div");
divtest.setAttribute("class", "form-group removeclass2" + company_room);
//var rdiv = 'removeclass2' + company_room;
divtest.innerHTML = '<div class="form-row"><div class="col-sm-5"> <div class="form-group pad-tp-5"><input type="text" class="form-control aj4" id="company_name" name="company_name" placeholder="Company Name"></div></div><div class="col-sm-2"> <div class="form-group"> <button class="btn btn-danger bdr-rds-100 btn-pad" type="button" onclick="remove_another_company(' + company_room + ');"> <i class="fa fa-minus"></i> </button> </div></div></div>';
objTo.appendChild(divtest);
var E_fields = $('.aj4');
var E_count = 1;
$.each(E_fields, function() {
jQuery(this).attr('id','company_name' + E_count);
jQuery(this).attr('name','company_name' + E_count);
E_count++;
});
}
function remove_another_company(rid2) {
company_room1--;
$('.removeclass2' + rid2).remove();
var E_fields = $('.aj4');
var E_count = 1;
$.each(E_fields, function() {
jQuery(this).attr('id','company_name' + E_count);
jQuery(this).attr('name','company_name' + E_count);
E_count++;
});
}

OK, so I didn't have your HTML so I had to mock some up. You will obviously have to tweak this a little to work with your ID's. I tried to keep it as close as possible to the ID's/classes you were already using.
I removed the pure javascript functions and the onclick events in favor of jquery since you were already using it. Hopefully this kind of simplifies things a bit and makes it more manageable.
NOTE: I added a hidden input field to keep track of company count. This way it will be included when you $(form).serialize in your ajax options (as you are adding it with a variable now). I included code to preserve the company_count variable also, so basically you will have 2 company counts. I did this just to show you an easier way to keep track of this without having to micro manage it. :)
Try out this code and let me know what your getting in console if it is not working. Thanks

When the cursor leaves the input box #select-or-enter-category, this code checks whether the given input exists in the dropdown or not

I have this code I use for showing a warning message:
<div class="row clearfix">
<div class="col-sm-8 col-sm-offset-2">
<div>
<div class="form-line focus">
<span class="category-status" style="color: red;">
This entered category is not found in the category list.<br>
Press button on the right to save this new category.
</span>
</div>
</div>
</div>
</div>
Then, I have another code use for typeahead dropdown:
<div class="row clearfix">
<div class="col-sm-7 col-sm-offset-2">
<div class="form-group form-float">
<div class="form-line focus">
<input type="hidden" id="cat-id" name="category_id" value="">
<input type="text" id="select-or-enter-category" name="category" data-provide="typeahead"
placeholder="Enter/Select a category" value="" required="required" class="form-control">
</div>
</div>
</div>
<div class="col-sm-1">
<button type="button" id="save-category" data-toggle="tooltip" data-placement="top" title=""
class="btn btn-warning" data-original-title="Save this input as New Category">
<i aria-hidden="true" class="fa fa-bookmark-o" style="display: inline;"></i>
</button>
</div>
</div>
And this is my javascript/jquery code:
When the user types keyword in an input box #select-or-enter-category,
this javascript code will give a dropdown as typeahead for the given keyword.
/**
* Autocomplete for category - ADD TASK MODAL
* #return {[type]} [description]
*/
$(document).ready(function(){
axios_get('/axiosCategory', function(data) {
var cat = [];
var $input = $("#select-or-enter-category");
let temp;
data.forEach(function(item) {
temp = {
id: item.id,
name: item.categoryName
}
cat.push(temp);
});
$input.typeahead({
source: cat,
autoSelect: true
});
$input.change(function() {
// console.log($input);
var current = $input.typeahead("getActive");
if (current) {
$('#cat-id').val(current.id);
}
});
});
});
When the cursor leaves the input box #select-or-enter-category, this code checks whether the given input exists in the dropdown or not. If not, the warning message will show up that will ask the user to save the input as a new category.
/**
* Display the message asking the user to save the
* new category
*
* #return void
*/
$('#select-or-enter-category').focusout(function() {
let val = $(this).val();
axios_get('/axiosCategory', function(data) {
let search = false;
data.forEach(function(item) {
if (val == item.categoryName) {
search = true;
}
});
if (search == false) {
$('.category-status').removeAttr('hidden');
} else {
$('.category-status').attr('hidden', true);
}
});
});
Then problem is that when the user clicks an item from the dropdown using the mouse, the error message shows up which is not what I want to happen.
I want the error message to show up only when the cursor actually leaves the input box #select-or-enter-category.
But if the user only uses keyboard for choosing an item from the dropdown and enter it, there is no problem.
Do you have any suggestions?

Try this one
$(document).ready(function(){
axios_get('/axiosCategory', function(data) {
dataGlobal = data;
var cat = [];
var $input = $("#select-or-enter-category");
let temp;
data.forEach(function(item) {
temp = {
id: item.id,
name: item.categoryName
}
cat.push(temp);
});
$input.typeahead({
source: cat,
autoSelect: true
});
$input.change(function() {
var current = $input.typeahead("getActive");
if (current) {
$('#cat-id').val(current.id);
}
});
$input.focusout(function() {
let val = $('#select-or-enter-category').val();
let current = $input.typeahead("getActive");
let search = false;
let str = current.name.substring(0,val.length);
if (str == val) {
val = current.name;
}
dataGlobal.forEach(function(item) {
if (val == item.categoryName) {
search = true;
}
});
if (search == false) {
$('#category-status').removeAttr('hidden');
} else {
$('#category-status').attr('hidden', 'hidden');
}
});
});
});

Adding Jquery UI to UL in HTML

I want to be able to add jquery UI to the list on GoalNotes This table gets populated by what the user enters in the "name1" and "data1" input fields.

The problem
The form with nane goalsList1 is sending whenever you click on the button.
Why? because the button is submit button.
The solution(s)
Replace the button's type to button. (link)
Prevent the form submission by event.preventDefault(). (link)
There are more ways but those are the major.
Note: your code still not working but now you can see the error message.

Validation in Jquery ajax form submission

I am trying to validate user to enter a unique mobile number and email id.
It is checking and showing result mobile/email exist or not but if it exists still the form is submitting. Since I am new to jQuery validation I am not able to figure out how I should do it correctly nor can I find a perfect tutorial to do it in a right way.
Here is my code, I know lots of mistakes would be there and I apologize for those small mistakes.
On my form I have given On blur function to check mobile number and email
From these two functions I am checking in database if exist or not
function check_availability() {
//get the mobile number
var main = $('#main').val();
//use ajax to run the check
$.post("tutor/check_mobile", {
main: main
},
function(result) {
//if the result is 1
if (result == 1) {
//show that the username is available
$('#mobile_availability_result').html(' ');
} else {
//show that the username is NOT available
$('#mobile_availability_result').html('Mobile Number already registered ');
}
});
}
function email_availability() {
//get the email
var main = $('#email_tuitor').val();
//$email = urldecode("[email]")
//use ajax to run the check
$.post("<?php echo base_url(); ?>tutor/check_email", {
main: main
},
function(result) {
//if the result is 1
if (result == 1) {
//show that the username is available
$('#email_availability_result').html(' ');
} else {
//show that the username is NOT available
$('#email_availability_result').html('Email already registered ');
}
});
}
This is the jquery ajax form submission is it possible to do every validation on blur ?
$(document).ready(function() {
$('.error').hide();
$("#next_tutor").click(function() {
$('.error').hide();
var main = $("#main").val();
if (main == "") {
$("label#main_error").show();
$("input#main").focus();
return false;
}
var name = $("#name").val();
if (name == "") {
$("label#name_error").show();
$("input#name").focus();
return false;
}
var email_tuitor = $("#email_tuitor").val();
if (email_tuitor == "") {
$("label#email_tuitor_error").show();
$("input#email_tuitor").focus();
return false;
}
var password_tuitor = $("#password_tuitor").val();
if (password_tuitor == "") {
$("label#password_tuitor_error").show();
$("input#password_tuitor").focus();
return false;
}
var tutor = $("#tutor").val();
// Returns successful data submission message when the entered information is stored in database.
var dataString = 'main=' + main + '&name=' + name + '&email_tuitor=' + email_tuitor + '&password_tuitor=' + password_tuitor + '&tutor=' + tutor;
// AJAX Code To Submit Form.
//alert(dataString);
//die;
$.ajax({
type: "POST",
url: "<?php echo base_url(); ?>tutor/tutor_sub_ses",
data: dataString,
cache: false,
success: function(result) {
//alert(result);
$("#abc").hide();
$("#tutorreg2").slideToggle("slow").show();
}
});
return false;
});
});
<form class="form-horizontal" action="#">

<div class="form-group">
<div class="col-sm-8">
<input type="password" class="form-control" id="password_tuitor" placeholder="Password">

</div>
<div class="form-group">
<div class="col-sm-8 text-right">
<button type="submit" class="btn btn-warning" id="next_tutor">Next</button>
</div>
</div>
</form>

The quick way will be to use a global switch to enable sending the form. I would to it this way:
Create global variables with default values
var mobileApproved = false, emailApproved = false;
Check status and prevent sending if value is false in click handler
$(document).ready(function() {
...
$("#next_tutor").click(function() {
if (!mobileApproved || !emailApproved) {
return false;
}
...
})
...
})
In your check functions manage approved status after each ajax response
...
$.post("tutor/check_mobile", {
main: main
},
function(result) {
//if the result is 1
if (result == 1) {
//show that the username is available
$('#mobile_availability_result').html(' ');
mobileApproved = true;
} else {
//show that the username is NOT available
$('#mobile_availability_result').html('Mobile Number already registered ');
mobileApproved = false;
}
});
...
$.post("<?php echo base_url(); ?>tutor/check_email", {
main: main
},
function(result) {
//if the result is 1
if (result == 1) {
//show that the username is available
$('#email_availability_result').html(' ');
emailApproved = true;
} else {
//show that the username is NOT available
$('#email_availability_result').html('Email already registered ');
emailApproved = false;
}
});

In order to stop the form from submission. You can keep a flag lets say formvalid.
Keep formValid as false initially. Based on your blur function, make it true if email and mobile are available else keep it false. In your form submission, put an if condition to check , if formvalid is true or not. If true then process with form submission else stop and throw error.
