I am trying to create a simple vote/poll program with javascript, I have tried to run it on xammp to see if it needed to be executed on a web server with no success. Do I need to include any script js files apart from vote.js like jquery or something? I am not sure.
Can someone help Thanks.

You only close html tag, didin't open tag

I am a beginner, so appreciate the patience on this one. I am trying to embed a really simple tab structure on my website. I'm not sure why it is not working. Here is the code below.
My guess it is something to do with the JS, but again, I am only really new to this.
Any help would be greatly appreciated! Thanks!
(I have used code found on CodePen for this)
<html lang="en" >
<head>
<script>$(function () {
var activeIndex = $('.active-tab').index(),
$contentlis = $('.tabs-content li'),
$tabslis = $('.tabs li');
// Show content of active tab on loads
$contentlis.eq(activeIndex).show();
$('.tabs').on('click', 'li', function (e) {
var $current = $(e.currentTarget),
index = $current.index();
$tabslis.removeClass('active-tab');
$current.addClass('active-tab');
$contentlis.hide().eq(index).show();
});
});</script>

There are lots of stuff happening there.
At first sight, you are not using JavaScript, you are using a library called JQuery, so you need to "import" it, otherwise that code won't work.
It must be placed before your JQuery code.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
I would recommend placing the code you've written at the bottom of the page, before the closing body tag
---> HERE
</body>
Improvements:
Separating your code into "modules" or smaller chunks.
Everything inside style tag, cut it and paste it in a new file, for example, style.css.
Everything inside script tag, cut it and paste it in a new file, for example, app.js.
After that import them, the JavaScript file, before the closing body tag, like mentioned before, and the css next to the others styles imports.
So, you'll end up with something like this:
Top of the page, inside head tag
...
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/normalize/5.0.0/normalize.min.css">
<link rel="stylesheet" href="./style.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
</head>
Bottom of the page, before closing body tag
...
<script src="./app.js"></script>
</body>
You can check which external sources are being used (like JQuery or Bootstrap) by clicking on the settings inside a Codepen environment. This particular script use JQuery, this can be imported in your <head> with a <script> tag using the online hosted version (CDN) or manually downloading it.
You can use this for now:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
you can use this code for creating your simple tabs
(function() {
'use strict';
var tabMenus,
tabContents;
tabMenus = document.querySelectorAll('.tab_menu_item_link');
tabContents = document.querySelectorAll('.tab_content');
for (var i = 0; i < tabMenus.length; i++) {
tabMenus[i].addEventListener('click', function(e) {
e.preventDefault();
for (var i = 0; i < tabMenus.length; i++) {
tabMenus[i].className = 'tab_menu_item_link';
}
this.className = 'tab_menu_item_link is-active';
for (var i = 0; i < tabContents.length; i++) {
tabContents[i].className = 'tab_content';
}
document.getElementById(this.dataset.id).className = 'tab_content is-active';
});

Reloading the page using JavaScript is very easy.
You can achieve this by using location.reload()
If you want to achieve reloading using a button, then be sure to add a return false; right after you call location.reload() to prevent bubbling (parents of the button won't know the event occurred).
So, your code will look something like this :
document.getElementById('yourButton').addEventListener('click', function(){
location.reload();
return false;
});
Hope this helps ! :)
I'm constructing a tree-view that slides out based on the buttons the user clicks in the preceding column. I get this error when I click on the first column of buttons:
Uncaught TypeError: $(...).effect is not a function
at runEffect1 (test:39)
at HTMLDivElement.<anonymous> (test:66)
at HTMLDivElement.dispatch (jquery-dbg.js:4737)
at HTMLDivElement.c3.handle (jquery-dbg.js:4549)
How do I fix it? These functions worked when I used vanilla JavaScript and without the SAPUI5 imported, but using jQuery now gives problems. I need to use SAPUI5 with jQuery. Also, the snippet doesn't work due to adding SAPUI5.
$(document).ready(function() {
$(function() {

function runEffect1() {
var selectedEffect = "slide";
var options = {};
/* Hide the columns so that they can slide into display*/
$("#column_2").hide();
$("#column_3").hide();
$("#column_4").hide();
// Run the effect
$("#column_2").effect(selectedEffect, options, 450, function() {
$("#column_3").effect(selectedEffect, options, 450, function() {
$("#column_4").effect(selectedEffect, options, 450, callback);
});
});
};
// Callback function to bring a hidden box back
function callback() {
setTimeout(function() {
$("#effect").removeAttr("style").hide().fadeIn();
}, 100);
};
// Set effect from select menu value
$("#column_1").on("click", function() {
runEffect1();
return false;

Normally you don't need the following code in your HTML, because they are duplicated
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
And where did you place the js code? The $(document).ready(function(){ one. It must be place after the all of the js library.
i have a Sidebar on the left of the Screen. I can toggle it by pressing a button. On the right I have the content.
I want to place the button on a horizontal bar on the top. The sidebar seems to cover this bar so I can not see the button.
This is my current code:
The Html File:

navIsOpen = !navIsOpen;
}
function SaveEntry(){ // save the entry
var txtTitle = $("#titleInputField").val();
var txtField = $("#textArea").val();
alert(txtTitle + "#" + txtField);
}
function NewEntry() { // create a new entry
alert("neuer Eintrag");
}
This is what I want to archieve
It seems I just have to fix the CSS to get it done.
I added margin-top:0; to your topBar and removed top: 0; from your sideNav.
Try this:
var navIsOpen = true;
function InitDocument(){ // Initialization
ToggleNavbar();
}
function ToggleNavbar(){ // show - hide the navbar
var sideNavWidth = "0px";
var mainAreaWidth = "0px";
if (navIsOpen)
{
sideNavWidth = "200px";
mainAreaWidth = "200px";
}
$("#sideNav").width(sideNavWidth);
$("#mainArea").css('margin-left',mainAreaWidth);
navIsOpen = !navIsOpen;
}
function SaveEntry(){ // save the entry
var txtTitle = $("#titleInputField").val();
var txtField = $("#textArea").val();
alert(txtTitle + "#" + txtField);
}

alert("neuer Eintrag");

Take a look flex-box concepts
Checkout this example of using the new HTML5 semantic elements.
http://www.w3schools.com/html/html5_semantic_elements.asp
I have taken most of the example elements from the link above and created a simple HTML5 page.
You can add/remove/modify any of the section below by removing the HTML or removing/adding additional CSS properties.
var toggleButton = document.getElementById('toggle-button');
var pageWrapper = document.getElementsByClassName('wrapper')[0];
toggleButton.addEventListener('click', function() {
toggleClass(pageWrapper, 'toggle-hidden')
});
function toggleClass(el, className) {
if (el.classList) {
el.classList.toggle(className);
} else {
var classes = el.className.split(' ');
var existingIndex = classes.indexOf(className);
if (existingIndex >= 0) classes.splice(existingIndex, 1);
else classes.push(className);
el.className = classes.join(' ');

Went through a few questions on stackoverflow but could not solve the error.
The intention is to modify and add html to the main document reading a JSON structure.
Uncaught TypeError: Cannot read property 'appendChild' of undefined
Update 1:-
Typo was corrected, marked in code.
Defer was introduced at script load in head section, this makes sure the entire document is loaded before the script starts execution.
Here I am trying to read a JSON, and then looping across its content to add to my main html document.
var json={
"fruit":[
{
"fruitname":"Apple",
"location":"data/png/apple.png",
"quantity":"25",
"price":"2"
},
{
"fruitname":"Mango",
"location":"data/png/mango.png",
"quantity":"35",
"price":"3"
}
]
};
//var cards = document.getElementsByClassName("content"); -- corrected typo
var cards = document.getElementById("content");
var fruits = json.fruit;
//alert(fruits.length);
//alert(fruits[1].fruitname);
for (var i = 0; i < fruits.length; i++) {
var cardelement=document.createElement('div');
cardelement.className = 'card';
// alert(cardelement);
cards.appendChild(cardelement);
var object = document.createElement('div');
object.className = 'object';
// alert(object);
cardelement.appendChild(object);
var image = document.createElement('img');
image.setAttribute("src", fruits[i].location);
object.appendChild(image);
var objectback = document.createElement('div');
objectback.className = 'object-back';
cardelement.appendChild(objectback);
var backfruit = document.createElement('div');
backfruit.className = 'back-fruit';
backfruit.innerHTML = fruits[i].fruitname;
objectback.appendChild(backfruit);
var backprice = document.createElement('div');
backprice.className = 'back-price';
backprice.innerHTML = fruits[i].price + "$ per unit";
objectback.appendChild(backprice);
var backquantity = document.createElement('div');
backquantity.className = 'back-quantity';
backquantity.innerHTML = "In Stock " + fruits[i].quantity + " units";
objectback.appendChild(backquantity);

Why was content undefined
You try to get content by ClassName
var cards = document.getElementsByClassName("content")[0];
But find content in your html:
<div id="content">
Notice that the ID is content. Either change it to class="content" or change the previous code to document.getElementByID("content");
Two issues:
There is no element with class content. On the other hand there is an element with that id. So you probably want to do:
document.getElementById("content");
The script runs too soon -- the elements are not loaded yet when it runs. Either put the script just before the closing </body> tag, or put the code inside an event handler, like
window.addEventListener('DOMContentLoaded', function() {
// your code
});
You are trying to access an element with class name content var cards =document.getElementsByClassName("content")[0]; & there is no class named content
You can modify your code like this ,
var cards = document.getElementById("content");
var json={
"fruit":[
{
"fruitname":"Apple",
"location":"data/png/apple.png",
"quantity":"25",
"price":"2"
},
{
"fruitname":"Mango",
"location":"data/png/mango.png",
"quantity":"35",
"price":"3"
}
]
};
var cards = document.getElementById("content");
var fruits = json.fruit;
//alert(fruits.length);
//alert(fruits[1].fruitname);
for (var i = 0; i < fruits.length; i++) {
var cardelement=document.createElement('div');
cardelement.className = 'card';
// alert(cardelement);
cards.appendChild(cardelement);
var object = document.createElement('div');
object.className = 'object';
// alert(object);
cardelement.appendChild(object);
var image = document.createElement('img');
image.setAttribute("src", fruits[i].location);
object.appendChild(image);
var objectback = document.createElement('div');
objectback.className = 'object-back';
cardelement.appendChild(objectback);
var backfruit = document.createElement('div');
backfruit.className = 'back-fruit';
backfruit.innerHTML = fruits[i].fruitname;
objectback.appendChild(backfruit);
var backprice = document.createElement('div');
backprice.className = 'back-price';
backprice.innerHTML = fruits[i].price + "$ per unit";
objectback.appendChild(backprice);
var backquantity = document.createElement('div');
backquantity.className = 'back-quantity';
backquantity.innerHTML = "In Stock " + fruits[i].quantity + " units";
objectback.appendChild(backquantity);
