JQuery setting CSS display: none when should be block - javascript

I'm looking to load a text file into a content div when the user selects a tab, the content is being inserted into the HTML file but the content div is being set to style="display: none;.
How can I get it to set the display to block whenever the relevant tab is selected and set all other contents divs to hide?
JQuery:
$(document).ready(function() {
function resetTabs() {
$("#content > div").hide();
$("#tabs a").attr("id", "");
}
var myUrl = window.location.href;
var myUrlTab = myUrl.substring(myUrl.indexOf("#"));
var myUrlTabName = myUrlTab.substring(0, 4);
(function () {
$("#content > div").hide();
$("#tabs li:first a").attr("id", "current");
$("#content > div:first").fadeIn();
$("#tabs a").on("click", function (e) {
e.preventDefault();
if ($(this).attr("id") == "current") {
return
}
else {
resetTabs();
$(this).attr("id", "current");
$($(this).attr('name')).fadeIn();
}
});
for (i = 1; i <= $("#tabs li").length; i++) {
if (myUrlTab == myUrlTabName + i) {
resetTabs();
$("a[name='" + myUrlTab + "']").attr("id", "current");
$(myUrlTab).fadeIn();
}
}
})()
});
$(document).ready(function() {
$("#tabContent1").load("test.txt");
$('a[name="#tab2"]').click(function() {
$("#tabContent2").load("test.txt");
});
});
HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="CSS/common.css" />
<script src="JS/common.js"></script>
<title></title>
</head>
<body>
<nav>
<ul id="tabs">
<li>Home</li>
<li>History</li>
<li>Specifications</li>
<li>Gallery</li>
</ul>
</nav>
<div id="content">
<div id="tabContent1"></div>
<div id="tabContent2"></div>
<div id="tabContent3"></div>
<div id="tabContent4"></div>
</div>
</body>
</html>
I'm also getting the following error:
Uncaught TypeError: Object #tabContent2 has no method 'fadeIn'
i
st.event.dispatch
st.event.add.y.handle

How are tabContent and the tab connected? Try setting the name of the tabs to the actual content id's like this:
<nav>
<ul id="tabs">
<li>Home</li>
<li>History</li>
<li>Specifications</li>
<li>Gallery</li>
</ul>
</nav>
<div id="content">
<div id="tabContent1"></div>
<div id="tabContent2"></div>
<div id="tabContent3"></div>
<div id="tabContent4"></div>
</div>
This way your function $($(this).attr('name')).fadeIn(); should work a little bit better.

try this for your fadeIn
var title = $('#current').attr('name');
$(title).fadeIn()
instead of
$($(this).attr('name')).fadeIn();
(oops check edit)

Got it working using a combination of #Jaco Koster JSFiddle and the following JQuery.
$(document).ready(function () {
$("#tabContent1").load("test.txt");
$('a[name="#tabContent1"]').click(function () {
$("#tab2").removeClass('activeTab');
$("#tab3").removeClass('activeTab');
$("#tab4").removeClass('activeTab');
$(this).addClass('activeTab');
$("#tabContent1").load("test.txt");
$("#tabContent1").show();
$("#tabContent2").hide();
$("#tabContent3").hide();
$("#tabContent4").hide();
});
$('a[name="#tabContent2"]').click(function () {
$("#tab1").removeClass('activeTab');
$("#tab3").removeClass('activeTab');
$("#tab4").removeClass('activeTab');
$(this).addClass('activeTab');
$("#tabContent2").load("test2.txt");
$("#tabContent2").show();
$("#tabContent1").hide();
$("#tabContent3").hide();
$("#tabContent4").hide();
});
$('a[name="#tabContent3"]').click(function () {
$("#tab1").removeClass('activeTab');
$("#tab2").removeClass('activeTab');
$("#tab4").removeClass('activeTab');
$(this).addClass('activeTab');
$("#tabContent3").load("test3.txt");
$("#tabContent3").show();
$("#tabContent1").hide();
$("#tabContent2").hide();
$("#tabContent4").hide();
});
$('a[name="#tabContent4"]').click(function () {
$("#tab1").removeClass('activeTab');
$("#tab2").removeClass('activeTab');
$("#tab3").removeClass('activeTab');
$(this).addClass('activeTab');
$("#tabContent4").load("test4.txt");
$("#tabContent4").show();
$("#tabContent1").hide();
$("#tabContent2").hide();
$("#tabContent3").hide();
});
});

Jquery - hover changes to click after several resizes

I am trying to build a basic tab-navigation. When I hover about a tab (step), then the background of the tab gets green.
But after several hovers/resizes of the browser, hover doesnt't work anymore. Then I have to click on the tab in order to get the green background. It kind of freezes.
Thats the jsFiddle:
https://jsfiddle.net/rob_the_mob_87/L84kyym1/
Here is my minimal code:
index.html
<html>
<head>
<title>Tabs</title>
<script
src="https://code.jquery.com/jquery-3.2.1.js"
integrity="sha256-DZAnKJ/6XZ9si04Hgrsxu/8s717jcIzLy3oi35EouyE="
crossorigin="anonymous"></script>
<script type="text/javascript" src="js/static.js">
</script>
<link rel="stylesheet" type="text/css" href="./css/main.css">
</head>
<body>
<div class="process_step active" id="1">Step 1</div>
<div class="process_step" id="2">Step 2</div>
</body>
</html>
main.css
.process_step{
}
.active{
background-color: green;
}
static.js
$(document).ready(function () {
bindShowStepHandlers()
});
this.bindShowStepHandlers = function () {
$('.process_step').each(function() {
$(this).hover(function () {
var clickedStepId = $(this).attr('id');
openStep(clickedStepId);
});
});
}
this.openStep = function (clickedStepId) {
$('.process_step').each(function() {
var stepId = $(this).attr('id');
if (stepId == clickedStepId) {
$(this).addClass('active');
} else {
$(this).removeClass('active');
}
});
}
check this snippet below. i think it is what you want..
$(document).ready(function() {
bindShowStepHandlers()
});
this.bindShowStepHandlers = function() {
$('.process_step').each(function() {
$(this).on('mouseenter',function() {
$(this).addClass('active');
});
$(this).on('mouseleave',function() {
$(this).removeClass('active');
});
});
}
.process_step {}
.active {
background-color: green;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="process_step active" id="1">Step 1</div>
<div class="process_step" id="2">Step 2</div>

Load navbar from external HTML and set current anchor class to active

I'm trying to load a navigation bar from an external HTML file, and automatically set an anchor's tag class to "active" based on the current page.
Here's the code:
<html>
<head>
<title>Main</title>
<style>
.active {
background-color: green;
}
</style>
<script>
$(document).ready(loadAndSet());
function loadAndSet() {
loadBar();
setActive();
}
function loadBar() {
$('#bar').load('navigation.html');
}
function setActive() {
var aObjects = document.getElementById("bar").getElementsByTagName("a");
for (var i = 0; i < aObjects.length; i++) {
if (document.location.href.indexOf(aObjects[i].href) >= 0) {
aObjects[i].className = "active";
}
}
}
</script>
</head>
<body>
<div id="bar"></div>
<h1>Content Title</h1>
<p>Some content</p>
</body>
</html>
And here's navigation.html:
<ul>
<li>Home</li>
<li>Page 2</li>
</ul>
What am I doing wrong?
EDIT:
New code:
<html>
<head>
<title>Main</title>
<style>
.active {
background-color: green;
}
</style>
<script>
$(document).ready(loadBar());
function loadBar() {
$('#bar').load('navigation.html', setActive);
}
function setActive() {
$("#home").addClass("active");
}
</script>
</head>
<body>
<div id="bar"></div>
<h1>Content Title</h1>
<p>Some content</p>
</body>
</html>
And navigation.html:
<ul>
<li><a id="home" href="index.html">Home</a></li>
<li><a id="page2" href="page2.html">Page 2</a></li>
</ul>
The navigation bar doesn't even load...
Your navigation.html code is missing the closing ul-Tag: change the last <ul> to </ul>.
The second problem is a little bit more difficulty. The page index.html can have multiple different values in document.location.href!
It can be:
http://www.stackoverflow.com/index.html
or
http://www.stackoverflow.com/
or even
http://www.stackoverflow.com
Your code wouldn't work for the last two versions of the url.
The third problem is, that the load() function can take a few seconds, so that the code isn't loaded at the time your setActive() is executed. You have to wait until load is finished. You can achieve this by using a callback function:
$(document).ready(loadBar());
function loadBar() {
$('#bar').load('navigation.html', setActive);
}
function setActive() {
var aObjects = document.getElementById("bar").getElementsByTagName("a");
for (var i = 0; i < aObjects.length; i++) {
if (document.location.href.indexOf(aObjects[i].href) >= 0) {
aObjects[i].className = "active";
}
}
}
You can give every link an unique id and then use this little javascript at the end of every site.
<script type="text/javascript">
$(document).ready( function(){
$("#IFOFYOURLINK").addClass("active");
});
</script>
EDIT:
Try to use
function loadBar() {
$('#bar').load("navigation.html", setActive);
}

HTML5 LocalStorage - simple issue with jQuery

it should be $('.filter-option a'), not $('.filters a').
localStorage setting true and false should change their places (true when it was false and vice versa).
if (checked) actually will work even for false value, because it turns out that checked is String, not Boolean. So it should be if (checked == 'true')
I also simplified some places in code.
Updated fiddle.
$(document).ready(function()
{
$('.filter-option a').on('click', function()
{
var data_filter = $(this).data('filter');
$(this).toggleClass("active");
localStorage.setItem(data_filter, $(this).hasClass("active"));
});
$('.filter-option a').each(function()
{
var data_filter = $(this).data('filter');
var checked = localStorage.getItem(data_filter);
if (checked == 'true')
{
$(this).addClass('active');
}
});
});

how to target specific css element in javascript?

I've got my code:
$(document).ready(function() {
$('#topznav ul li').click(function() {
$('#topznav').animate({
marginLeft: '10px'
}, 400);
});
});
I've got a question about the second line. It won't work. I mean, nothing really animates. The script file is loaded correctly because other functions work. What am I doing wrong here?
try this:
$(document).ready(function() {
$('#topznav ul li').click(function() {
$('#topznav').animate({
marginLeft: '+=10px'
}, 400);
});
});
Here I am posting what I got
<html>
<head>
<script src="http://code.jquery.com/jquery-1.9.0.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#topznav ul li').click(function() {
$('#topznav').animate({
marginLeft: '+=10px'
}, 400);
});
});
</script>
</head>
<body>
<div id="topznav">
<ul >
<li>
test1
</li>
<li>
test2
</li>
<li>
test3
</li>
</ul>
</div>
</body>
</html>
This works fine
