Show child elements if parent is visible

I'm trying to have my form show child elements if the parent is visible and I keep getting an "undefined" error with my child element, even though I have it defined. I'm trying to have set this up where:
Q1: Checked responses will show parent elements (divs).
Q2: Depending on this response, it'll show child elements (divs).
Is there a way to do this?
//Next Tab
function next() {
var formTabOne = document.getElementById("stepOne");
formTabOne.classList.add("formTrans");

target.classList.remove("formTrans");

.getElementsByClassName returns a collection, bizMgr and bizEE are both collections. You have to iterate the collections and set each element to style.display = 'block'. You can't just call xxx.style.display on a javascript collection. You would want to change your code like the following:
if (q2value == "1") {
if (biz.style.display = "block") {
//bizMgr.style.display = "block"; -NO
//bizEE.style.display = "block"; -NO
for(let i = 0; i < bizMgr.length; i++){
bizMgr[i].style.display = "block";
}
for(let j = 0; j < bizEE.length; j++){
bizEE[j].style.display = "block";
}
}
} else {
if (biz.style.display = "block") {
//document.getElementsByClassName("bizEE").style.display = "block"; -NO
for(let j = 0; j < bizEE.length; j++){
bizEE[j].style.display = "block";
}
}
}

Why does my page refresh when I press buttons?

This is the relevant code of my page :
HTML :
<button class="ajout-col"><i class="fas fa-columns"> Ajouter une colonne</i></button>
<div class="table-responsive">
<table class="table">
<thead>
<tr>
<th></th>
<th>
<button class="btn"><i class="fas fa-trash remove-col"></i></button>
<button class="btn"><i class="fas fa-text-height text-col"></i></button>
<button class="btn"><i class="fas fa-sort-numeric-down nbr-col"></i></button>
<input type="text" class="form-control">
</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<button class="btn"><i class="fas fa-trash remove-row"></i></button>
</td>
<td>
<input type="text" class="form-control">
</td>
</tr>
</tbody>
</table>
</div>
<button class="ajout-lig"><i class="fas fa-list-ul"> Ajouter une ligne</i></button>
Javascript :
$('body').on('click', '.remove-row', function() {
$(this).parents('tr').remove();
});
(Any button of the grid refreshes my page, I just put the remove-row one because it's the shortest code only for clarity purpose)
(Issue is located on the second tab, just fill info on the first tab to be able to access the second tab)
Any time I press a button from the grid, it refreshes my page
I searched on google and it appears I have to add "return false" or "e.preventDefault();" to fix the issue, and I tried, but it only fixes partially the issue
If I add any of those at the end of each .on('click'), it fixes the issue for Adding a column or a row
But deleting a row or a column is going to work 1 or 2 times, and then my page is going to refresh again... same for the other buttons (text and number buttons)
Thanks in advance for any help ! :)

This happens because a button with no type attribute acts as type="submit" and also try to submit the form data to server and refresh the page finally. Please try to set the type to the buttons like type="button" for no page refreshes.
<button class="ajout-col" type="button">
<i class="fas fa-columns"> Ajouter une colonne</i>
</button>

Replace <button class="ajout-lig"><i class="fas fa-list-ul"> Ajouter une ligne</i></button>
to
<button class="ajout-lig" type="button"><i class="fas fa-list-ul"> Ajouter une ligne</i></button>
I think this problem is due to, these buttons are actually submitting the form. if we doesn't specify the button type, it will take as a submit type button

Validation for email or phone number for same text field in angularjs

I am working on registration form for my project in AngularJs. Users can register with his/her Email/Phone. I need to validate that particular text-box.
I have validations for both, with different text fields, with ng-pattern. But how can I validate for both in one text field?
I have updated my code, here:- enter code here
http://plnkr.co/edit/mCVxHxl2DIvqOYtVapRN?p=preview

Use /^([_a-z0-9]+(\.[_a-z0-9]+)*#[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,5}))|(\d+$)$/
Demo

You can use a pipe '|' to OR two regular expressions together:
/<email-pattern>|<phone-pattern>/
so your final regex would be:
/^([_a-z0-9]+(\.[_a-z0-9]+)*#[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,5}))|\d+$/

You can use angular form validation and ng-pattern directive for input use ng-pattern="/^(?:\d{10}|\w+#\w+\.\w{2,3})$/"
Working Demo
var app = angular.module("MY_APP", []);
app.controller("MyCtrl", function($scope) {
$scope.submitted = false;
$scope.submit = function(userData){
console.log(userData)
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="MY_APP">
<div ng-controller="MyCtrl">
<form name="userForm" novalidate ng-submit="userForm.$valid && submit(userData)">
<div class="errorMsg" ng-show="submitted==true && userForm.$invalid">
<ul>
<li ng-show="submitted==true && userForm.emailphone.$error" class="errorMsg">
wrong format, It should be email or 10 digit mobile number
</li>
</ul>
</div>
<input type="text" name="emailphone" ng-model="userData.user" id="emailphone" required
ng-pattern="/^(?:\d{10}|\w+#\w+\.\w{2,3})$/" />
<button type="submit" ng-click="submitted = true">Submit</button>
</form>
</div>
</div>

Here is an example as well.

function validate(){
var value = $("#email_phone").val();
var regex = new RegExp('^([a-zA-Z0-9_\.\-])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})|(^[0-9]{10})+$');
if(value){
if(!regex.test(value)){
$("#error").text("Please enter valid email address or phone number.")
}else{
$("#error").text('')
}
}else{
$("#error").text('This field is required.')
}

This code might work for you: Here is the ans of your question
<script type="text/javascript">
function validate(){
var phoneNo = document.getElementById('txtEmailormob');
var c=document.forms["myForm"]["email"].value;
var atpos=c.indexOf("#");
var dotpos=c.lastIndexOf(".");
var errorMsg = document.getElementById("errorMsg");
var successMsg = document.getElementById("successMsg");
if(phoneNo.value==""||phoneNo.value==null){
errorMsg.style.display="block";
document.getElementById("errorMsg").innerHTML = "Please enter your Mobile No or Email ";
return false;
}
if ((phoneNo.value.length < 10 || phoneNo.value.length > 10) && (atpos<1 || dotpos<atpos+2 || dotpos+2>=c.length)) {
errorMsg.style.display = "block";
successMsg.style.display = "none";
document.getElementById("errorMsg").innerHTML = " Mobile No. is not valid, Please Enter 10 Digit Mobile No or Please Enter valid Email. ";
return false;
}
successMsg.style.display = "block";
document.getElementById("successMsg").innerHTML = " Success ";
errorMsg.style.display = "none";
return true;
}
</script>

Javascript div show hide onclick with image sprite

I am trying to work on writing a div swap with images using javascript. I have created two divs. One which is display block, and the second div which is display none. When the user clicks on the image, an onclick is supposed to hide the showing div and show the hidden div in it's place.
When the user clicks the same image location, the image shifts based on the xy value and the divs are supposed to swap out again. I cannot seem to get this to function correctly. I can get the click to swap out the divs when I don't set the display on either divs, but that leaves both divs showing stacked. I am almost there but cannot find what I am missing to only show one div at once. Is there a better way that I could be doing this? Please help?

Here is my javascript:

}
else {

text.innerHTML = "hide";
}
}
</script>

The following code should work for you, although you are really better off attaching your events using addEventListener() instead of inline in the HTML. You also identified the id lhtext twice in your HTML, which is not allowed.
function lhtrial() {
ele = document.getElementById("trialarea");
ele2 = document.getElementById("trialarea2");
if (ele.style.display === "none") {
ele.style.display = "block";
ele2.style.display = "none";
} else {
ele.style.display = "none";
ele2.style.display = "block";
}
}
