How come multiple classes not targeting in textarea?

I want to use validate_empty_field function for both classes .log and .log2. For some reason only .log is targeted but .log2 textarea is not. When you click on text area, if empty, both should show validation error if the other one is empty or if both empty.
$(document).ready(function() {
$('#field-warning-message').hide();
$('#dob-warning-message').hide();
var empty_field_error = false;
var dob_error = false;
// $('input[type=text], textarea')
$('.log, .log2').focusout(function () {
validate_empty_field();
});
function validate_empty_field() {
var field = $('.log, .log2, textarea').val();
// var first_name_regex = /^[a-zA-Z ]{3,15}$/;
if (field.length == '') {
$('#field-warning-message').show();
$('#field-warning-message').html("Please fill out form!");
empty_field_error = true;
} else if (field.length < 1) {
$('#field-warning-message').show();
$('#field-warning-message').html("Please fill out form!");
empty_field_error = true;
} else {
$('#field-warning-message').hide();
}
}
$('.verify-form').submit(function () {
empty_field_error = false;
dob_error = false;
validate_empty_field();
if ((empty_field_error == false) && (dob_error == false)) {
return true;
} else {
return false;
}
})
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<textarea class="log"></textarea>
<textarea class="log2"></textarea>
<div id="field-warning-message"></div>

You should pass the event to the handler so you have access to the target
Change your event listener line to this:
$('.log1, .log2').focusout(validate_empty_field);
and then accept an argument in validate_empty_field
function validate_empty_field(ev){
var field = $(ev.target).val();
if(!field.length){
//textarea is empty!
}else{
//textarea is not empty!
}
}
in fact, you could do all of this in an anonymous function you have already created, and use the on method to stick with JQuery best practices:
$('.log1, .log2').on('focusout', function(){
if(!$(this).val().length){
//this textarea is empty
}else{
//this textarea is not empty!
}
});
And yes, adding one class to all textareas and swapping out .log1, .log2 for that class would be a better option.
EDIT: Final option should cover all requirements.
$('.log').on('focusout', function(){
$('.log').each(function(){
if(!$(this).val().length){
//this textarea is empty
}else{
//this textarea is not empty!
}
}
});

JS a div is not showing after page refresh

In registration form I have a 2 radio button, when one button is selected a dropdown list appears. But after register fails, the selected radio button remains but the dropdown list is not shown anymore, I want the dropdown list to be shown after register fail. There should be a solution with local storage but I dont know exactly how to write it.
here is the code, what I should add to make it happen?
$(document).ready(function() {
$('input[type=radio][name=rdUserType]').change(function() {
if (this.value == '1') {
$('#cityClient').show();
$('#cityLawyer').hide();
}
else if (this.value == '0') {
$('#cityClient').hide();
$('#cityLawyer').show();
}
});
});

So I found the solution finally, I tried and made it :
<script>
$(document).ready(function() {
$('input[type=radio][name=rdUserType]').change(function() {
if (this.value == '1') {
$('#cityClient').show();
$('#cityLawyer').hide();
}
else if (this.value == '0') {
$('#cityClient').hide();
$('#cityLawyer').show();
}
localStorage.removeItem("last");
});
});
function fix(){
var check = localStorage.getItem("last");
console.log(check);
if (check === 'a') {
$('#cityClient').hide();
$('#cityLawyer').show();
}
else{
$('#cityClient').show();
$('#cityLawyer').hide();
}
}
function save(){
// rdAttorney is a id of the selected radio
if (document.getElementById('rdAttorney').checked) {
localStorage.setItem('last', 'a');
}
else{
localStorage.setItem('last', 'b');
}
}
window.onload = fix();
</script>

javascript which I wrote is wrong(may be)

I have tried to write js for my html form. js is working fine with the logically. But if logic fails,I mean if any condition fails it reloads the page,which I don't want. I am providing the code. Please point me out the mistake in js if any.
window.onload = function() {
document.getElementById('submitlink').onclick = function() {
var bflag = document.addpro.brandflag;
var brand = document.addpro.brand1.value;
var cflag = document.addpro.catflag;
var cat = document.addpro.cat1.value;
var color1 = document.addpro.color1.value;
var color2 = document.addpro.color2.value;
if(cb_validation(bflag,brand))
{
if(cb_validation(cflag,cat))
{
if(colorcheck(color1,color2))
{
document.getElementById('addproform1').submit();
return false;
}
}
}
}
function cb_validation(flag,field)
{
if(flag[0].checked)
{
if(field==0)
{
alert('Please Select Both Brand And Category');
field.focus();
return false;
}
else
return true;
}
else
return true;
}
function colorcheck(c1,c2)
{
if((c1==0) && (c2==0))
{
alert('Please Select Both Colours');
document.addpro.color1.focus();
return false;
}
else if((c1==0))
{
alert('Please Select 1st Colour');
document.addpro.color1.focus();
return false;
}
else if((c2==0))
{
alert('Please Select 2nd Colour');
document.addpro.color2.focus();
return false;
}
else
return true;
}
}
I am rookie in js. Please also tell me if I have done any mistake.

return false is what keeps the page from reloading. Right now it is inside your final color check condition. If you never want the page to reload it needs to be after your first cb_validation condition.

Submit() is causing the page refresh which is in below line
document.getElementById('addproform1').submit();
Also both your function is returning true becauseyou are returning true in else block. Hope this points you to right direction....
Good luck....

jquery form validation without click -> when ok show div

is it possible to do this automatically. mean when i type text and click on the second textfield autocheck the first one. then when both ok show the div2 and so on.
here is some code
var step1 = function() {
var first = $("#f_name").val();
var last = $("#l_name").val();
var error = false;
if (first == "") {
$("#f_name").next().text("*ErrorMsg");
error = true;
} else {
$("#f_name").next().text("");
}

} else {
returnfalse;
}
}
$(document).ready(function() {
$('#div1').hide();
$('#div2').hide();
$("#send").click(step1);
$("#send2").click(step2);
});
hope anyone can help me. and sorry for my bad english :)

The way that I would do it is:
Assign a variable, something like numSteps and set its initial value to 1
onFocus and onBlur, run a function that steps through each field, based on numSteps
If any fields are empty (or however you want to validate them), set error = true
if !error numSteps++
Make all elements up to numSteps visible
Hope this helps
Very crude example, but demonstrates what I was referring to:

HTML / Javascript - Trouble changing text when clicked

So I have some HTML code here:
<body>
<b style="font-size: 26px;">How the game works</b>
<u id="HowToPlay_HideShow" style="color: #9FF;">[hide]</u><br>
</body>
And I also used Javascript to turn the hide text into show, and show back into hide when clicked on.
<script>
var HowGameWorks_Hidden = false;
document.getElementById("HowToPlay_HideShow").onclick = function () {
if (HowGameWorks_Hidden == false) {
document.getElementById("HowToPlay_HideShow").innerHTML = "[show]";
HowGameWorks_Hidden = true;
}
if (HowGameWorks_Hidden == true) {
document.getElementById("HowToPlay_HideShow").innerHTML = "[hide]";
HowGameWorks_Hidden = false;
}
}
</script>
This, however, does not seem to work. Clicking on the hide and show text has no effect at all. So I tried removing this piece of code:
if(HowGameWorks_Hidden == true) {
document.getElementById("HowToPlay_HideShow").innerHTML = "[hide]";
HowGameWorks_Hidden = false;
}
And it correctly turns the hide text into show when I click it (but, of course, does not turn the show text back into hide).
So how do I get my code working?

This is because your second if statement will always get triggered if your first one does, since you set HowGameWorks_Hidden to true in it. You need to use an else:
if(HowGameWorks_Hidden == false) {
document.getElementById("HowToPlay_HideShow").innerHTML = "[show]";
HowGameWorks_Hidden = true;
}
else if(HowGameWorks_Hidden == true) {
document.getElementById("HowToPlay_HideShow").innerHTML = "[hide]";
HowGameWorks_Hidden = false;
}
