Hello people I created two divs and when i hover to h3 shows me something. I want display this only when i click on h3. How i can do this?
How to change hover to click? When i do this doesn't working.
Sorry for my bad language.
$(document).ready(function () {
$('li.requirement').hover(function () {
$(this).find('span').show();
}, function () {
$(this).find('span').hide();
});
});
#wrap {
background: #e7e7e7;
padding: 0px;
text-align: center;
width: 100%;
}
#left, #right {
background: #ccc;
display: inline-block;
padding: 20px;
}
li {
list-style-type: none;
padding: 0px;
margin: 0px;
}
span.lewy {float:right; background:red; padding:20px;}
span.prawy {float:left; background:red; padding:20px;}
h3 {text-align:center;}
h3.praw {float:left;}
h3.lew {float:right;}
.calosc {max-width:500px; margin: 0 auto; border:1px solid red;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="wrap">
<div id="left"><div class="lef">
<li class="requirement" id="requirement_1">
<h3 class="lew">SPR</h3>
<span class="fr drag lewy" style="display:none;">1 kontakt</span>
</li>
</div></div>
<div id="right"><div class="praf">
<li class="requirement" id="requirement_2">
<h3 class="praw">SPR 2</h3>
<span class="fr drag prawy" style="display:none;">2 kontakt</span>
</li>
</div></div>
</div>

You can use .on('click', function(){}); and then inside this function you check to see if it's already visible or not. Take a look here
EDIT
As you want to be just the <h3> clickable, i made an adjustment in the code below, and now you need to cehck for the visibility of the h3 parent, because now the context of this is now h3 and no more the li
$(document).ready(function () {
$('.clickableH3').on('click', function () {
if ($(this.parentElement).find('span').is(":visible")){
$(this.parentElement).find('span').hide();
}else{
$(this.parentElement).find('span').show();
}
});
});
#wrap {
background: #e7e7e7;
padding: 0px;
text-align: center;
width: 100%;
}
#left, #right {
background: #ccc;
display: inline-block;
padding: 20px;
}
li {
list-style-type: none;
padding: 0px;
margin: 0px;
}
span.lewy {float:right; background:red; padding:20px;}
span.prawy {float:left; background:red; padding:20px;}
h3 {text-align:center;}
h3.praw {float:left;}
h3.lew {float:right;}
.calosc {max-width:500px; margin: 0 auto; border:1px solid red;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="wrap">
<div id="left"><div class="lef">
<li class="requirement" id="requirement_1">
<h3 class="lew clickableH3">SPR</h3>
<span class="fr drag lewy" style="display:none;">1 kontakt</span>
</li>

<div id="right"><div class="praf">

Well you see, in your js code, where you have "hover" ? Well you type "click" there instead ...

The jQuery hover function can have 2 parameters, which is your case. The first one for the hover, the second is for the unhover
So if you want to be able to close and hide on click I advise to use some css and use toggleClass. But if you wan to keep only javascript you can do like this:
$(document).ready(function () {
$('li.requirement').click(function () {
var $elm = $(this);
if( $elm.hasClass('showed') ){
$elm.find('span').removeClass('showed').hide();
}else{
$elm.find('span').addClass('showed').show();
}
});
});

Web menu button to keep a different color

I don't probably know how to search for this precise question and I haven't found anything, so I am sorry if there is already asked somewhere.
I only have 3 buttons and the index is the "Inicio" page. I've applied a :hover to the buttons, but I want to keep it fixed for the button of the displayed page. Obviously, I want to have "Inicio" in this state at the beginning.
(jsfiddle below)
<!-- menu -->
<nav id="nav">
<ul>
<a id=inicio href=#><li class="boton"><p class="text_menu">INICIO</p></li></a>
<a id=productos href=#><li class="boton"><p class="text_menu">PRODUCTOS</p></li></a>
<a id=contacto href=#><li class="boton"><p class="text_menu">CONTACTO</p></li></a>
</ul>
</nav>
#nav {
padding-top: 27px;
padding-left: 25%;
}
#nav ul li {
list-style:none;
display:inline-block;
margin-left: 4%;
text-align: center;
font-family: 'Dosis', sans-serif;
font-size: 100%;
color: #FFF;
}
.text_menu {
padding-top: 5px;
}
.boton {
width: 15%;
height: 57px;
background-color: #0099ff;
border-radius: 10px 10px 0px 0px;
-moz-border-radius: 10px 10px 0px 0px;
-webkit-border-radius: 10px 10px 0px 0px;
border: 0px solid #000000;
}
.boton:hover {
background-color: #0033ff;
}
Here is a jsfiddle:

Thanks for your responses.

U can simply add class like .hovered to current button like
HTML:
<li class="boton hovered"><p class="text_menu">CONTACTO</p></li></a>
CSS:
.hovered {
background-color: #0033ff;
}
UPD: Fiddle
UPD2: For page changing
U simply can add and remove class on `click' like:
$('nav ul a').on('click', function(){
$('nav ul a li.hovered').removeClass('hovered');
$(this).children('li').addClass('hovered');
})
Fiddle2

If you want to use without JQuery, you have to use it in javascript
HTML :
<a id="mnu1" class="mnu hovered" src="#" onclick="makeSelected('mnu1')"> One </a>
<a id="mnu2" class="mnu" src="#" onclick="makeSelected('mnu2')"> Two </a>
<a id="mnu3" class="mnu" src="#" onclick="makeSelected('mnu3')"> Three </a>
CSS :
.mnu{
background-color : #451;
margin-left:20px;
font-size:30px;
}
a:hover{
background-color:#ccc;
}
.hovered{
background-color:#ccc;
}
JS :
var prev_mnuid= "mnu1";
function makeSelected(mnuid){
document.getElementById(prev_mnuid).className = "mnu";
document.getElementById(mnuid).className = "mnu hovered";
prev_mnuid=mnuid;
}

dynamically changing text in div

Can someone please take a moment to look over this and let me know where I am going wrong in my code?
For some reason, the content div won't change when the buttons are clicked.
It's very simple, and right now I feel very confused for not being able to find my error.
CSS:
#wrapper {
margin: 0 auto;
width:100%;
max-height: 133px;
font-family:Arial, Helvetica, sans-serif;

line-height:1.5em;
}

text-indent: -5000px;
display:block;

}
JavaScript:
$('button').bind('click', function() {
$('div#content').html($('div#content' + ($(this).index()+1)).html());
});

The selector $('button') is the problem. You don't want to select a button - element but an element within the div #button, am I right?
So you should take $("#button a") as selector, if you want to append the event handler to all links within the #button element.

David Müller had it correct regarding the button selector being an issue.
The switching wasn't occurring with the event on the link because the index of the links will be 0 since both are only children. If the event is instead on the parent div, the switching works. Below is a jsfiddle and the code.
http://jsfiddle.net/VrKsh/2/
<div id="wrapper">
<div id="button">
<div id="button1">
Content1
</div>
<div id="button2">
Content2
</div>
</div>
<div id="content">
<div id="content1">
<ul>
<li>Stuff1</li><br />
<li>Stuff1</li><br />
<li>Stuff1</li>
</ul>
</div>
<div id="content2" style="display:none;">
<ul>
<li>Stuff2</li><br />
<li>Stuff2</li><br />
<li>Stuff2</li>
</ul>
</div>
</div>
<script type="text/javascript">
$('#button div').bind('click', function() {
$('div#content div:visible').hide();
$('div#content' + ($(this).index() + 1)).show();
});

Creating a dropdown menu

I have a menu that contains a submenu which gets displayed below the main menu when a link inside the main menu is hovered over. What I want to do is add a second submenu inside the first submenu but make it a dropdown. I am not that great at css and I was wondering if anyone can help me with this. I haved followed some tutorials online and I was not able to get the results I was looking for. Here is the html and css I have so far.
<div id="navigation">
<ul id="mymenu">
<li>Home</li>
<li>Gallery</li>
<li>What We Do</li>
<li>Contact</li>
</ul>
</div>
<div id="sublinks">
<ul id="s1">
<li>General</li>
<li>Landon News</li>
<li>Trust Us</li>
</ul>
<ul id="s2">
<li>
Security Systems
<ul id="s2sys">
<li>Arlington HA</li>
<li>Enfield HA</li>
<li>Revere HA</li>
</ul>
</li>
<li>
WLAN Systems
<ul id="s2wlan">
<li>Beverly HA</li>
<li>Holyoke HA</li>
<li>Meriden HA</li>
<li>Revere HA</li>
</ul>
</li>
</ul>
<ul id="s3">
<li>Computers</li>
<li>Strategic Planning</li>
<li>Security Systems</li>
<li>WLAN, WiFi Broadband</li>
</ul>
<ul id="s4">
<li>Email</li>
<li>Address Info</li>
</ul>
</div>
Here is the javascript for the main menu which will display the first submenu
function showsubmenu(id){
submenu = document.getElementById('s'+id);
for(i=1;i<=4;i++){
if(i==id){
submenu.style.display="block";
} else {
document.getElementById('s'+i).style.display="none";
}
}
}
sfHover = function() {
var sfEls = document.getElementById("sublinks").getElementsByTagName("li");
for (var i=0; i<sfEls.length; i++) {
sfEls[i].onmouseover=function() {
this.className+=" hover";
}
sfEls[i].onmouseout=function() {
this.className=this.className.replace(new RegExp(" hover\\b"), "");
}
}
}
if (window.attachEvent) window.attachEvent("onload", sfHover);
Here is the CSS
#navigation{
height:32px;
margin:0 auto;

}
#navigation ul{
height:32px;

}
#sublinks li li a:hover {
background-color: #8db3ff;
}
/* ----------- Hide Sub menu ----------- */
#s2, #s3, #s2sys, #s2wlan{display:none;}
What I am trying to do is make the second submenu a dropdown from the first submenu and at the moment it displays within the same line and not as a dropdown. How can I do this?

http://jsfiddle.net/kVztG/1/
To make the sub-sub-menu a dropdown change the css below.
#sublinks li:hover li {
display:block;
position:relative;
top:30px;
}
The position:relative and top:30px stop the dropdowns from appearing ontop of the sub-menu, and display:block stops the li from display inline.

Try adding this css to your drop down ul list that is within your sub-menu.
position: absolute;
top: 30px;
Depending on the type of result your looking for, you might want to amend the top value, or have the dropdown vertical by adding a width

Simple javascript issue - list is NOT expanding correctly

The CSS:
#divMainMenu ul {
list-style-type: none;
padding: 5px 0;
height:400px;
}
#divMainMenu li {
height: 17px;
margin: 3px 0;
padding: 14px 2px;
border: 1px solid #eee7cb;
background: url(../../Images/50pTransparent-20x20.png) repeat;
}
#divMainMenu li ul{
display: none;
}
The html and script:
<script type="text/javascript">
function Show(pObj)
{
pObj = document.getElementById(pObj).id;
if (document.getElementById(pObj).style.display=='none')
document.getElementById(pObj).style.display='block';
else
document.getElementById(pObj).style.display='none';
}
</script>
<div id="divSidePanel">
<div id="divMainMenu">
<ul>
<li onclick="Show('Buyers')">Buyers
<ul id="Buyers" style="display:none;">
<li>Search</li>
<li>Submit request</li>
<li>Send message to owner</li>
</ul>
</li>
<li>Sellers</li>
<li>Contact Us</li>
</ul>
</div>
</div>
The problem:
When I click on the text Buyers, it shows the sub/nested list. However, the other items do not make space for the nested list. Thus the nested list writes over the space of the main list.
Is this a problem with my code or is it the standard way it's meant to work? And is there a way to let the other items 'push down' making way for the nested items?
Thanks!

You need to use min-height: instead of height: in the CSS. If you know jQuery, the .hide() and .show() functions will work MUCH better.

Take this out of your css:
#divMainMenu li ul{
display: none;
}
And change the height property to min-height on your #divMainMenu li selector
Resultant css:
#divMainMenu ul {
list-style-type: none;
padding: 5px 0;
height:400px;
}
#divMainMenu li {
min-height: 17px;
margin: 3px 0;
padding: 14px 2px;
border: 1px solid #eee7cb;
background: url(../../Images/50pTransparent-20x20.png) repeat;
}
#divMainMenu li ul{
}​
