I have two textboxes and one button,
I want to add one new textfield, that should show card name from textbox1 and Link URL append from textbox2 when I click on button
//AddnNewCardNavigator
var counter=2;
var nmecardtxt= document.getElementById("textbox1").value;
var linkurltxt= document.getElementById("textbox2").value;
$("#addbutton").click(function(){
if(nmecardtxt ==""||nmecardtxt ==0||nmecardtxt ==null
&& linkurltxt ==""||linkurltxt ==""|| linkurltxt ==0||linkurltxt ==null){
alert("Please insert value in Card name and Link Url textboxes and must be correct");
return false;
}
var NewCarddiv = $(document.createElement('div')).attr("id",'cardlink'+counter);
NewCarddiv.after().html()
})
</script>
<!-- text boxes-->
<div class="row">
<div class="col-md-12">
<div id="textboxesgroup">
<div id="textboxdiv1">
<label style="color:blanchedalmond">Card Name: </label><input type="textbox" id="textbox1">
</div>
<div id="textboxdiv2">
<label style="color:blanchedalmond">Link Url: </label><input type="textbox" id="textbox2">
</div>
</div>
</div>
</div>
Your variables nmecardtxt and linkurltxt must be created inside the click function,
because it's empty at the loading of the page.
I also took the liberty to use jQuery for that variables, as you're already using it, and tried to enhance some other things:
(See comments in my code for details)
//AddnNewCardNavigator
var counter = 2;
// On click function
$("#addbutton").click(function() {
// Here it's better
var nmecardtxt = $("#textbox1").val();
var linkurltxt = $("#textbox2").val();
// Modified you test here
if (!nmecardtxt || !linkurltxt) {
alert("Please insert value in Card name and Link Url textboxes and must be correct");
return false;
}
// Modified creation of the card
var link = $(document.createElement('a')).attr("href", linkurltxt).html(linkurltxt);
var NewCarddiv = $(document.createElement('div')).attr("id", 'cardlink' + counter).html(nmecardtxt + ": ").append(link);
$('#cards').append(NewCarddiv);
//NewCarddiv.after().html(); // Was that line an attempt of the above ?
});
body {
background: #888;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Hope it helps.
Here's a simplified version of what you're trying to accomplish:
function addNewCard() {
var name = $('#name').val();
var url = $('#url').val();
var count = $('#cards > .card').length;
if (!name || !url) {
alert('Missing name and/or URL.');
}
var card = $('<div class="card"></div>').html("Name: " + name + "<br>URL: " + url);
$("#cards").append(card);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label for="name">Name:</label>
<input type="text" id="name" name="name">
<label for="url">URL:</label>
<input type="text" id="url" name="url">
<input type="submit" value="Add Card" onclick="addNewCard();">
<div id="cards">

I am trying to learn some javascript in web programming. Starting with a simple school registration webpage: the webpage allows to dynamically create any number of grades by clicking "Grade+" button; under each grade, any number of students can be created by clicking "Student+" button. "Grade+" button works as expected, however clicking "Student+" button does not present the student information, not sure what is happening. Any help will be highly appreciated. Thanks in advance.
The reference codes:
<!DOCTYPE html>
<html>
<body>
<div>
<label>Registration</label>
<div class="form-inline justify-content-center" id="school" style="display:none">
<label for="fname">Grade:</label>
<input type="text" id="grade" name="Grade"><br><br>
<div id="students">
<div id="student">
<label for="fname">First:</label>
<input type="text" id="first" name="First"><br><br>
<label for="lname">Last:</label>
<input type="text" id="last" name="Last"><br><br>
</div>
<div class="text-center" id="add_student">
<span id="idStudentRootCopy">----S----</span>
<button type="button" onclick="addItem('student', 'idGradeRootCopy', false)">Student+</button>
</div>
</div>
</div>
<div class="text-center" id="add_grade">
<span id="idGradeRootCopy">----G----</span>
<button type="button" onclick="addItem('school', 'idGradeRootCopy', true)">Grade+</button>
</div>
</div>
<script>
var count = 0;
function addItem(id, index, root) {
var original = document.getElementById(id);
var before = document.getElementById(index);
var clone = original.cloneNode(true);
clone.style.display='block';
clone.id = id + ++count;
var newFields = clone.childNodes;
for (var i = 0; i < newFields.length; i++) {
var fieldName = newFields[i].name;
if (fieldName)
newFields[i].name = fieldName + count;
}
if (root) {
original.parentNode.insertBefore(clone, before.parentNode);
} else {
original.insertBefore(clone, before);
}
}
</script>
</body>
</html>
If you open up the developer tools of your browsers and click the Student+ button you'll get an error message like:
Uncaught DOMException: Node.insertBefore: Child to insert before is
not a child of this node
So you're actually trying to put the cloned node into the wrong spot. Either way things are a bit confusing. Let's say you have clicked the Grade+ button three times and now you decide to click on Student+ of the first clone - how should it know where to put the student as there are three grades?
Well there's a fix of course. Each Student+ button is a child of an unique clone of the school <div> which you also gave an unique id yet (school1, school2,...). So if you pass the addItem() function a reference to the button you actually clicked, we can get it's parent div like:
clickedElement.parentNode.parentNode.parentNode
and add the cloned node using appendChild() instead of insertBefore().
Here's an example (just click on 'Run code snippet'):
var count = 0;
function addItem(id, index, root, clickedElement) {
var original = document.getElementById(id);
var before = document.getElementById(index);
var clone = original.cloneNode(true);
clone.style.display = 'block';
clone.id = id + ++count;
var newFields = clone.childNodes;
for (var i = 0; i < newFields.length; i++) {
var fieldName = newFields[i].name;
if (fieldName)
newFields[i].name = fieldName + count;
}
if (root) {
original.parentNode.insertBefore(clone, before.parentNode);
} else {
clickedElement.parentNode.parentNode.parentNode.appendChild(clone);
}
}
<div>
<label>Registration</label>
<div class="form-inline justify-content-center" id="school" style="display:none">
<label for="fname">Grade:</label>
<input type="text" id="grade" name="Grade"><br><br>
<div id="students">

</div>
</div>
<div class="text-center" id="add_grade">
<span id="idGradeRootCopy">----G----</span>
<button type="button" onclick="addItem('school', 'idGradeRootCopy', true,this)">Grade+</button>
</div>
</div>
Update
If you click on the Grade+ button, it will automatically also 'create' a student input field as it's div is part of the school div. So move it out of the school div and change it's display mode to none.
If you want the new student input field to appear right before the Student+ button, we indeed need to use .insertBefore().
Here's the modified example:
var count = 0;
function addItem(id, index, root, clickedElement) {
var original = document.getElementById(id);
var before = document.getElementById(index);
var clone = original.cloneNode(true);
clone.style.display = 'block';
clone.id = id + ++count;
var newFields = clone.childNodes;
for (var i = 0; i < newFields.length; i++) {
var fieldName = newFields[i].name;
if (fieldName)
newFields[i].name = fieldName + count;
}
if (root) {
original.parentNode.insertBefore(clone, before.parentNode);
} else {
clickedElement.parentNode.insertBefore(clone, clickedElement);
}
}

I am creating a multi-page form (by which I mean on certain button clicks, specific elements change between hidden and visible) following this page's setup. I have 2 pages: 1. add animal and 2. add another animal. I would like to be able to repeat page 2 as many times as the user clicks the button add another animal before they click submit, and store all the inputted animal names to be sent to a python function (so every time a user types in a name on the add another animal page, the previous animal's name isn't overwritten.
My HTML, CSS, and JS are below.

I've this structure here:
<div>
<div class="row">
<input id="1a">
<input id="1b">
</div>
<div class="row">
<input id="2a">
<input id="2b">
</div>
<div class="row">
<input id="3a">
<input id="3b">
</div>
<div class="row">
<input id="4a">
<input id="4b">
</div>
</div>
If the user leaves everything empty, there is no problem. But when he enters for example something into 1a and leaves 1b empty, this should cause an error. So how can I find out if a & b is filled for each row? It's a bit tricky and I have no idea how to deal with this.
You can achieve it in this simple way
$('button').on("click", () => {
$('body').find(".row").each(function(index, row){
var count = 0;
$(row).find("input").each(function(i, input) {
if($(input).val() !== "")
count++;
})
if(count === 1)
alert("Row " + (index + 1) + " is invalid");
});
});

something like that ?
const inRow = document.querySelectorAll('.row')
, valida = document.querySelector('button')
, respon = document.querySelector('output')
;
valida.onclick =_=>
{
let OK = true
inRow.forEach(eR=>
{
let vals = 0
eR.querySelectorAll('input').forEach(eI=>{ vals+=eI.value.length ? 1:0 })
if (vals===1) OK=false
})
respon.value = OK ? 'OK' : 'bad'
}

Normally multiple form controls (ex <input>, <textarea>, <select>, etc) should be inside a <form> tag. Moreover, the behavior described is called form validation which requires said <form> tag to be triggered by a "submit" event.
The following demo features proper HTML
<form> and <fieldset> instead of <div>
added <output> for each <fieldset>
Also the JavaScript is designed to show a message when any pair of <input> has a .value and the other doesn't.
The message: <output>Complete data input</output>
This pseudo-form validation is triggered whenever a user enters data within an <input> and then clicks (aka "blur" event). This entire chain of actions combined is the "change" event.
The <form> tag is registered to the "change" event so if any of the <input> within the <form> is the event origin (aka event.target - the <input> that the user triggers a "change" event on).
const form = document.forms[0];
form.onchange = reqData;
function reqData(event) {
let origin = event.target;
if (origin.tagName === 'INPUT') {
const parent = origin.parentElement;
const output = parent.querySelector('output');
const inputs = [...parent.querySelectorAll('input')];
let total = inputs.length;
let count = 0;
for (let input of inputs) {
if (input.value) {
count++;
}
}
if (count < total && count > 0) {
output.style.opacity = '1';
} else {
output.style.opacity = '0';
}
}
return false;

I made a JQuery function to check for empty required fields inside a closed custom dropdown.
If a required field is empty inside one of the dropdown and if the dropdown is currently closed I want the dropdown to open and if there are no empty values in the required fields I want the dropdown to close.
The problem is that the required fields aren't accessible if the dropdowns are closed and I tried to fix that problem with this function.
For some reason, it only checks for these input fields if the form is submitted at least once and the required fields are opened at least once.
find(':input[required]') doesn't give any output if the dropdown isn't opened at least once, once u open and close the dropdown the function works.
This is the function:
function dropdown_required() {
var required = 0;
$('#visible_fields').find(':input[required]').each(function () {
if (!this.value) {
for (var i = 1; i < 15; i++) {
$('.form_' + i).find(':input[required]').each(function () {
$(this).prop('required', false);
});
}
required++;
}
});
if (required == 0) {
for (var i = 1; i < 15; i++) {
var empty = 0;
$('.form_' + i).find(':input[required]').each(function ()
{
if(!this.value) {
empty++;
}
});
if (empty !== 0) {
if ($(".arrow_" + i).hasClass("rotate_2")) {
$(".arrow_" + i).addClass("rotate_1").removeClass("rotate_2");
$(".form_" + i).fadeToggle();
}
} else if ($(".arrow_" + i).hasClass("rotate_1")) {
$(".arrow_" + i).addClass("rotate_2").removeClass("rotate_1");
$(".form_" + i).fadeToggle();
}
}
}
}

Your function checks if your arrow element has the class rotate_2. The code you pasted has neither rotate_1 or rotate_2 and no else block, so the toggle never executes.
Problem demonstration:
// This group has empty mandatory elements
var empty = 1;
$('#validate').click(function() {
if (empty !== 0) {
console.log("I have empty elements!");
// From your comments, this might be backwards
if ($(".arrow_1").hasClass("rotate_2")) {
console.log("I'm going to show them");
$(".arrow_1").addClass("rotate_1").removeClass("rotate_2");
$(".form_1").fadeToggle();
}
// This is missing in the code
else {
console.log("I wasn't invited to the party");
}
// -------
} else if ($(".arrow_1").hasClass("rotate_1")) {
console.log("I'm out, I don't have empty elements...");
$(".arrow_1").addClass("rotate_2").removeClass("rotate_1");
$(".form_1").fadeToggle();
}
});
$('#simulate').click(function() {
// Simulates manually opening and closing
// In short, add rotate_2 class as if it's been toggled
$('.arrow_1').addClass('rotate_2');
console.log("Toggled manually");
})

I'm trying to change the innerHTML of a div and fade it in when a input in my form comes into focus. I also want to test whether or not it's been faded in at all because when the page loads it will begin faded out.
To summarize, I essentially want to display a tooltip in another div and switch the tooltip with fading in and out as my inputs come into focus on my form.
Here's what I have so far:
<script type="text/javascript">
var visible = 0;
var nameText = "<p>May I get your<br/>full name?</p>";
var emailText = "<p>Could I please<br/>get your email<br/>address?</p>";
var messageText = "<p>What is the<br/>message you<br/>would like to send?</p>";
$('.inp').on("focus", function(event){
if (visible == 0)
{
var fadeTime = 1;
visible = 1;
}
else
fadeTime = 500;
$('bubble').fadeOut(fadeTime).html(function() {
if ($this.attr('id') == "name")
return nameText;
else if ($this.attr('id') == "email")
return emailText;
else if ($this.attr('id') == "message")
return messageText;
}).fadeIn(500);
});
</script>
I'm not receiving any JavaScript errors. My HTML for my bubble and inputs looks like this:
<footer class="container">
<div class="row reveal">
<div class="mailman fourcol">
<img src="images/mailman.png" alt="The Mail Man" />
<div id="bubble">

I did some fix to you. Check the demo.
The main problems are:
focus event should be fired on input element, $('.inp').on("focus", function(event){ should be $('.inp').on("focus", 'input', function(event){
$this.attr(id), you missed var $this = $(this); outside, or just use var id = this.id;.
$('bubble') should be $(#bubble)
