Prevent refresh of page after alert - javascript

I am trying to validate a form. I am successful on that, but if the alert kicks in, the page refresh and since i am using a pop up, this one closes and i have to open it again. I need to prevent that in the case of a miss click.
Here are the code:
HTML
<div class="row">
<form action="" method="" id="formBoard" name="formOfBoard">
<div class="col-75">
<label for="bname">Name of the Board: </label><br>
<input type="text" id="boardname" name="boardname">
</div>
<div class="row">
<div class="col-75">
<label for="ipadd">IP Address:</label><br>
<input type="text" name="ipadd" id="ipaddress">
</div>
</div>
<div class="row">
<div class="col-75">
<label for="portnum">Port:</label><br>
<input type="text" name="portnum" id="portnum">
</div>
</div>
<div class="row">
<div class="col-75">
<label for="imgadd">Upload image:</label><br>
<img src="node_modules/#tabler/icons/icons-png/file-upload.png" alt="Insert image" class="insrtimg" name="imageboard" id="insertimage">
</div>
</div>
<div class="row">
<div class="col-80">
<div>
<div class="btnfrm" style="background-color: #F30D0DBF; color:antiquewhite" onclick="closeForm()">Discard</div>
<input type="submit" class="btnfrm" style="background-color: rgb(67, 221, 67);" value="Save" onclick="validateIndexForm()">
</div>
</div>
</div>
</form>
</div>
</form>
</div>
JavaScript
function validateIndexForm(){
let x = document.getElementById("boardname").value;
let y = document.getElementById("ipaddress").value;
let z = document.getElementById("portnum").value;
let w = document.getElementById("insertimage").value;
let ipfrmt = /^(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/;;
if(x == ""){
alert("Please insert the boards name");
return false;
}
if(!y.match(ipfrmt)){
alert("Please insert a valid IP address");
return false;
}
if(z != isNaN() && !(z > 0)){
alert("Please insert the correct port");
return false;
}
return x, y, z;
}

The likely reason for the reload may be from the form action that is returning the default values into the URL, meaning it is causing new navigation (this can be seen in the dev console, such as chrome, by turning this on via the dev tool preferences.
I have tested this only with the HTML/JavaScript so not sure what other parts of the application are doing but hopefully this helps.
Change the button onclick to the form onsubmit action
passing through the event to the function
prevent default when an error occurs
<div class="row">
<form action="" method="" id="formBoard" name="formOfBoard" onsubmit="validateIndexForm(event)">
<div class="col-75">
<label for="bname">Name of the Board: </label><br>
<input type="text" id="boardname" name="boardname">
</div>
<div class="row">
<div class="col-75">
<label for="ipadd">IP Address:</label><br>
<input type="text" name="ipadd" id="ipaddress">
</div>
</div>
<div class="row">
<div class="col-75">
<label for="portnum">Port:</label><br>
<input type="text" name="portnum" id="portnum">
</div>
</div>
<div class="row">
<div class="col-75">
<label for="imgadd">Upload image:</label><br>
<img src="node_modules/#tabler/icons/icons-png/file-upload.png" alt="Insert image" class="insrtimg" name="imageboard" id="insertimage">
</div>
</div>
<div class="row">
<div class="col-80">
<div>
<div class="btnfrm" style="background-color: #F30D0DBF; color:antiquewhite" onclick="closeForm()">Discard</div>
<input type="submit" class="btnfrm" style="background-color: rgb(67, 221, 67);" value="Save" >
</div>
</div>
</div>
</form>
</div>
</form>
</div>
function validateIndexForm(event){
let x = document.getElementById("boardname").value;
let y = document.getElementById("ipaddress").value;
let z = document.getElementById("portnum").value;
let w = document.getElementById("insertimage").value;
let ipfrmt = /^(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/;;
if(x == ""){
event.preventDefault();
alert("Please insert the boards name");
return false;
}
if(!y.match(ipfrmt)){
event.preventDefault();
alert("Please insert a valid IP address");
return false;
}
if(z != isNaN() && !(z > 0)){
event.preventDefault();
alert("Please insert the correct port");
return false;
}
return x, y, z;
}
Note: to make further improvements to the lines of code that are repeated (prevent default) the function could be broken out into a validation function that returns true or false based on the inputs.

Unintentional popup FORM closing when clicking on a BUTTON or on a INPUT ( with JS code)

I'm finding a strange behaviour in a popup FORM when I click on a BUTTON (that operates on some object using a JS code), and on a INPUT (used for submit): in both cases, the form closes, and it is an unexpected action.
Probably is due to something very easy and common that I'm not fixing, but i can't find it.
This is the HTML interested part:
<form name="contactform" id="contactform" class="contact-form">
<div class="contactform-container">
<div class="common">
<label for="name">Nome</label>
<input type="text" id="name" name="name" />

</div>
</form>
</div>
The BUTTON that create problem is the one with class reloadButton.
The INPUT is the one with id submit.
I think css aren't necessary.
Regarding the JS part:
let formEls = formPopup.querySelectorAll('.common, .message, .note');
let charCode = [];
const refreshButton = document.querySelectorAll('.reloadButton')[0];
const passInput = document.getElementById('password');
window.onload = function () {
document.querySelector('#reserveBtn').addEventListener('click', function () {
formPopup.classList.add('active');
});
getCode();
formPopup.querySelector('.closeButton').addEventListener('click', function () {
cleanForm();
formPopup.classList.remove('active');
});
formPopup.addEventListener('click', function (ev) {
if (ev.target.id == 'contactform-bg') {
cleanForm();
formPopup.classList.remove('active');
}
});
refreshButton.addEventListener('click', function (ev) {
charCode = [];
getCode();
});
passInput.addEventListener('keyup', function () {
passVal = passInput.value;
checkPass(passVal);
});
};
let cleanForm = function () {
formEls.forEach((item, i) => {
item.classList.remove('typing');
});
// console.log(window['contactform-bg'].innerHTML);
// console.log(document.getElementById('contactform').innerHTML);
// console.log(document.contactform.innerHTML);
document.contactform.name.value = '';
document.contactform.familyName.value = '';
document.contactform.email.value = '';
document.contactform.message.value = '';
passInput.value = '';
};
function getCode() {
let sChars = 'A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,0,1,2,3,4,5,6,7,8,9,!,#,#,$,%,^,&,*,(,)';
let arrayChars = sChars.split(',');
for (var i = 0; i <= 3; i++) {
// trova un indice casuale tra 0 e la lunghezza dell'array
RefIndex = Math.floor(Math.random() * arrayChars.length);
// assegna il carattere estratto dall'array (strana indicazione del font come giapponese(??)
let char = arrayChars[RefIndex];
charCode[i] = char.toLowerCase;
createImgCaptcha(char, i);
}
}
I avoid to add the createImgCaptcha function because it just create CANVAS and doesn't have any impact on the matter.
Is there anyone able to explain to me why the FORM closes? I tried following the steps in JS but found no errors.
Thanks in advance.
Ok, I found the problems and fixed them.
There were little mistakes one different from another. So, I list them:
The "FORM close object": there was a missing '#' characer in the ref attribute, so I changed the HTML from to , adding also the type attribute for greater completeness.
The "class reloadButton": I finally read that a <button>Click to do something</button> is a default submit button. I didn't know... so, I just added the right type attribute to solve, in this way: <button class="reloadButton" type="button">.
The "submit button": in this case, I changed the prevent JS command: function stopEvent(event) { event.preventDefault();}.
Now, everything works correctly. Sorry if I bored you with these silly things; either way, it's always best to learn from mistakes.

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).

Replicating and differentiating portions of a form

UPDATE:
Using the code that colecmc provide(Thank you!!) I updated the codepen. I like how the date.now is added, but I would like to just do a an incremental increase. Im not sure how to apply that to this function I tried zer00ne's index incremental but am doing something wrong.
let cloneList = [],
index = 0; // index must be declared apart from function or else you will set it to the initial value every time the function is called.
document.getElementById('launch').onclick = function(event) {
event.preventDefault();
var addOnDiv = document.getElementById('addon');
var container = document.getElementById('add-components')
var clonedNode = addOnDiv.cloneNode(true);
var component = clonedNode.querySelector('input');
index++;
clonedNode.id = index+1;
cloneList.push(clonedNode.id);
component.id = `componentID_${clonedNode.id}`;
component.name = `componentName_${clonedNode.id}`;
container.appendChild(clonedNode);
}
Im having an issue with my form. Initially I had two forms on the page. However on submit only the info from the first form was written. I tried combining the forms. Now if i fill out the campaign and component inputs and submit it writes to the correct tables(good!). However the component section is supposed to be replicated. A campaign can have as many components as the user wants. I am using cloneNode and before I combined the table it added more component sections. Now that they are combined the function no longer works. Im confused if this is even the right approach for what Im doing. I included a copdpen that shows a stripped down version of what Im trying to do.
Basically I want to be able to press add component, add as many new components as I'd like fill them out and have then all written as records to the db. I need a way to differentiate all the clones (new ids or names?)

JS:
document.getElementById('launch').onclick = function() {
var addOnDiv = document.getElementById('addon');
var container = document.getElementById('add-components')
var clonedNode = addOnDiv.cloneNode(true);
container.appendChild(clonedNode );
}
You will want to try something like this before appending to the container clonedNode.id = Date.now();
That will provide a way to differentiate all the clones by giving a unique id. You can take it a step further like this:
let cloneList = [];
document.getElementById('launch').onclick = function(event) {
event.preventDefault();
var addOnDiv = document.getElementById('addon');
var container = document.getElementById('add-components')
var clonedNode = addOnDiv.cloneNode(true);
var component = clonedNode.querySelector('input');
clonedNode.id = Date.now();
cloneList.push(clonedNode.id);
component.id = `componentID_${clonedNode.id}`;
component.name = `componentName_${clonedNode.id}`;
container.appendChild(clonedNode);
}

This is the closest I came to what I believe is your way of thinking by looking at your code. (I also removed some unnecessary steps in your code to make it a little bit cleaner). This is for if you must have different names and ID:s on your inputs. However, if you can manage to have the same for both (i.e. component_0, other_0 etc.), you can remove the "names" array and the "names" forEach.
When you want to add an input to your addon-div, just add the ID (and name if you decide to keep it), without the "_0", to the array/s as in the example.
Change the name to "otherName_0" and ID to "otherID_0" in your html and this should work.
var i = 1;
document.getElementById('launch').onclick = function(event) {
event.preventDefault();
var addOnDiv = document.getElementById('addon');
var container = document.getElementById('add-components')
var clonedNode = addOnDiv.cloneNode(true);
var ids = ['componentID', 'otherID'];
var names = ['componentName', 'otherName'];
ids.forEach(function(id) {
var currentInput = clonedNode.querySelector(`#${id}_0`);
currentInput.id = `${id}_${i}`;
});
names.forEach(function(name) {
var currentInput = clonedNode.querySelector(`input[name=${name}_0]`);
currentInput.name = `${name}_${i}`;
});
container.appendChild(clonedNode);
i++;
}

Validating all form fields -- function not working correctly

I created a html form and a function validateForm() to validate the form fields. However the function is only reporting issues with wrong email input, and its not validating the other fields in the form. Can you check my code to see if i have any errors.
Thanks

Edit: I just noticed you're using a class contentform and I thought it was an id. I would also add an id to your form to be able to retrieve all form data with one DOM traversal instead of several.
Also, the reason the email is the only one working is because the browser is validating the email without using your JS.
First I would ditch all the variables declared and replace it with the form object.
var formObject = document.getElementById('contentform');
Then you could check whatever child elements that are required. I would also remove the nesting of your if statements, and instead of alerting an error and returning false, add the error to an array to store each one, then return after all items are validated.
var errorList = [];
var isValid = true;
if(formObject.jobNumber == "") {
errorList.push('Please enter a valid job number');
isValid = false;
}
Then rinse and repeat for each element required. After that, just return the list and status (isValid).
// this should be on its own at the bottom of your function right before you return
if (!isValid) {
alert(errorList);
// I would add some formatting or preferably display in the form view.
}
return isValid;
html file
// add the event handler here
<button type="submit" onclick="validateForm()" class="bouton-contact">Send</button>
Also, these
if (!isValid) {
alert(errorList);
}
should be removed from each if statement and placed at the bottom after all have been checked.
Here you validate your email address: First pass the id to javascript by post method then the function validation() will works.
//html
<div>
<input type="text" name="email" id="email" class="" data-wow-delay=".5s" value="" placeholder="Email..." />
</div>
<span id="emailerror" style="display:none; color:#F00">Enter valid email id*</span>
<input type="submit" onClick="return validation();" class="wow fadeInUp" value="Send" />
//javascript
function validation()
{
var email = document.getElementById('email').value;
if(email == '' || !(/^\w+([\.-]?\w+)*#\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(email)))
{
document.getElementById('emailerror').style.display = 'inline';
var error=1;
}
else
{
document.getElementById('emailerror').style.display = 'none';
}
if(error == 1)
{
return false;
}
else
{
return true;
}
}
now your email validation works fine, thanks

How to Validation that User should enter any of two field

form html
<form action="" method="post" name="add_new_report" id="add_new_report" enctype="multipart/form-data" onsubmit="return AddNewReport(this)">
<div class="field">
<div class="field_180">Cheque</div>
<div class="field_30">:</div>
<div class="field_220">
<input type="text" name="cheque" id="cheque" onChange="updatesum()" />
</div>
<div class="clear"></div>
</div>
<div class="field">
<div class="field_180">Cash</div>
<div class="field_30">:</div>
<div class="field_220">
<input type="text" name="cash" id="cash" onChange="updatesum()" />
</div>
<div class="clear"></div>
</div>
<div class="field">
<div class="field_210"> </div>
<div class="field_222">
<input type="submit" id="Submit" name="Submit" value="Submit" />
</div>
<div class="clear"></div>
</div>
</form>
in this form user should enter either cheque or cash Field how is it possible ? i don't want to be both are mandatory.
If you absolutely do not care about IE <9 you could use something like the following. (otherwise replace the code not working in IE, with some that does)
function oneShouldHaveData(ids) {
var elements = [];
//convert ids to elements (map no IE<9)
elements = ids.map(function (id) {
return document.querySelector('#' + id);
});
//returns true if any element matches expression (some no IE <9)
return elements.some(function (element) {
//could be validation for anything (greater 0 etc.)
return !!element.value;
});
}
//just submit setup :)
document.querySelector('#add_new_report').addEventListener('submit', function () {
console.log(oneShouldHaveData(['cheque', 'cash']));
});
http://jsfiddle.net/LXprX/1/
Simply add this function to your header:
<script>
function validateForm()
{
var x=document.forms["add_new_report"]["cheque"].value;
var y=document.forms["add_new_report"]["cash"].value;
if ((x==null || x=="") && (y==null || y==""))
{
alert("At least one entry should be filled");
return false;
}
else
return true
}
</script>
and change the following field:
onsubmit="if(validateForm()) return AddNewReport(this)"
You can also include AddNewReport in validateForm function and only return validate(this) function.
