Toggling Background Color on Click with Javascript

I am working on a class project and need to be able to toggle the background color of a transparent png on click. I have been working through a number of examples from the site, but I can't get it working. I am a total novice at Javascript and haven't had luck trying to plug in jQuery code either.
Here is the targeted section:
<div class="expenseIcon"><a href="#">
<img src="images/mortgage.png"></a><br/>
<p>Rent or Mortgage</p>
</div>
On clicking the linked image, the goal is for the background on the image to change to green. Clicking it again would change it back to the default, white. Here's the CSS I'd like to toggle on/off with click.
.colorToggle {
background: #A6D785;
}
I had tried adding class="iconLink" to the href and class="iconBox" to the image with the following Javascript adapted from another post, but it didn't work.
var obj = {};
$(document).ready(function () {
$(".iconLink").click(function () {
var text = $(this).find(".iconBox");
obj.var1 = text;
//alert(obj.var1);
//return false;
$('.iconBox').removeClass('colorToggle');
$(this).addClass('colorToggle')
});
});
Any advice would be greatly appreciated!

Let's break down what is happening with your current code when you click the link.
var obj = {};
$(document).ready(function () {
$(".iconLink").click(function () {
var text = $(this).find(".iconBox");
obj.var1 = text;
$('.iconBox').removeClass('colorToggle');
$(this).addClass('colorToggle')
});
});
JQuery finds all elements with the classname "iconBox". In your case, this is the img element. The reference to that element is then saved in "obj.var1". You do not end up doing anything with this reference, so these two lines can be removed.
All elements with the class "iconBox" have the class "colorToggle" removed. Your img element didn't have this class on it, so nothing happens.
The class "colorToggle" is added to the anchor element. Yes! Now the element wrapping the img has a background color.
Unfortunately, clicking the anchor tag again won't do anything, since the anchor tag will already have the "colorToggle" class and all we would be doing would be trying to add it again. Hmm. Let's try changing addClass to toggleClass. Here's our new code:
$(document).ready(function () {
$(".iconLink").click(function () {
$(this).toggleClass('colorToggle');
}
});
Also, note that because we're working with the anchor element, the p element won't be affected by this change. If you want the entire div to change background colors, use this line instead:
$(".expenseIcon").toggleClass('colorToggle');

Using the given markup:
<!-- to toggle the bg-color onClick of anchor tag -->
<div class="expenseIcon">
<a href="#">
<img src="images/mortgage.png">
</a>
<br/>
<p>Rent or Mortgage</p>
</div>
since the question asks for javascript, heres an option for updating the background-color of an element using the built-in js.style method
//get a handle on the link
//only one element w/ className 'expenseIcon'
//first child of 'expenseIcon' is the anchor tag
var link = document.getElementsByClassName('expenseIcon')[0].children[0];
//get a handle on the image
var image = link.children[0];
//listen for click on link & call bgUpdate()
link.addEventListener('click', bgUpdate, false);
function bgUpdate() {
if(image.style.backgroundColor === 'lightgoldenrodyellow'){
image.style.backgroundColor = 'aliceblue';
} else if (image.style.backgroundColor === 'aliceblue') {
image.style.backgroundColor = 'lightgoldenrodyellow';
}
else console.log('image bgColor: ' + image.style.backgroundColor);
}
a similar example

css
.expenseIcon{
background: red;
}
.colorToggle {
background: blue;
}
jquery
$(".expenseIcon").click(function () {
$('.expenseIcon').toggleClass('colorToggle');
});
By default, the div will have expenseIcon background. ToggleClass will toggle the div class with colorToggle so will override the previous color.
You don't need an hyperlink tag A to manage clicks, just put it on the DIV.

adding and removing a class upon slidetoggle

I have created a 3 x 2 grid of squareish buttons that are monotone in colour. I have a slidetoggle div that pops down inbetween both rows of 3 and as it does so it pushes the content down of the rest of hte page, this is all working perfectly so far.
But i have made a class (.active) thats css is the same as the :hover state so that when i hover over a button the coloured version replaces the monotone version, however i have tried to add some js to make the colour (.active) stay on once i have clicked on a certain button so that you can see which button (product) the slidedown div relates to and the rest are still in monotone around it...
The .active code below works perfectly to turn the bottons colour on and off when you click that one button, but i have set it up so that if one button's div is open and you click on a different one, the open one closes and then the new one opens. This feature however throws off the balance of the code i have for the .active state here. When you have say button 1 open and you click button 1 to close, this works fine, the color goes on and then off, but if yo uhave button 1 open and click on button 2, button 1's div closes and opens button 2's div but then botton 1 stays in colour as button 2 turns to colour. the order is thrown off...
I need to add some js to say, that only one button can be in color (.active) at a time, or that if one is .active it must be turned off before the new one is turned on... Please help :)
$(document).ready(function(){
$("a.active").removeClass('active'); //<<this .active code &
$("#product1").click(function(){
if($(this).parent('a').hasClass('active')){ //<<<this .active code
$(this).parent('a').removeClass('active'); //<<
}else{ //<<
$(this).parent('a').addClass('active'); //<<
} //<<
$("#product2box").slideUp('slow', function() {
$("#product3box").slideUp('slow', function() {
$("#product4box").slideUp('slow', function() {
$("#product5box").slideUp('slow', function() {
$("#product6box").slideUp('slow', function() {
$("#product1box").stop().slideToggle(1000);
//do i need
//something here??
});
});
});
});
});
});
And here is the HTML
<div id="row1">
<a href="#!" class="active"><span id="product1">
<div id="productblueheader">
<div id="productlogosblue1"></div>
</div>
<div id="productstitle">Stops all spam and unwanted email.</div>
<div id="producttext">With over 8 million users ******* is the leading in anit-spam software on the market today! Sort all your spam issues in one place now!</div>
</span></a>
<a href="#!" class="active"><span id="product2">
<div id="productblueheader">
<div id="productlogosblue2"></div>
</div>
<div id="productstitle">The easiest email encryption ever.</div>
<div id="producttext">In todays world, we won’t enter personal details in to untrusted websites, but we send personal information via regular (insecure) email all the time.</div>
</span></a>
<a href="#!" class="active"><span id="product3">
<div id="productblueheader">
<div id="productlogosblue3"></div>
</div>
<div id="productstitle">The easiest email encryption ever.</div>
<div id="producttext">****** is a revelation in security and ease of use. Get the best protection against viruses, spyware, scam websites and other threats.</div>
</span></a>
</div>
(then the same for row2 products 4-6)

you use .each() method of jquery and find .active class to remove it,
and then add .active class.
$(this).parent('a').each(function(){
$(this).removeClass('active');
});
$(this).parent('a').addClass('active');

This ought to work, but I couldn't test it without the relevant HTML:
$(document).ready(function () {
$("#product1").click(function () {
$("a.active").removeClass('active');
$(this).parent('a').toggleClass('active'));
$("#product2box").slideUp('slow', function () {
$("#product3box").slideUp('slow', function () {
$("#product4box").slideUp('slow', function () {
$("#product5box").slideUp('slow', function () {
$("#product6box").slideUp('slow', function () {
$("#product1box").stop().slideToggle(1000);
});
});
});
});
});
});
});
Also, there would probably be a better way to write all those sliding up functions. Do they really need to go on by one by the way?

$(document).ready(function() {
$(".producthandler").click(function() {
var ctx = $(this);
var productboxId = ctx.children().eq(0).attr("id");
ctx.toggleClass('active');
$("#" + productboxId + "box").stop().slideToggle(1000);
$(".producthandler").each(function() {
var ctx = $(this);
var producthandlerId = ctx.children().eq(0).attr('id');
if (productboxId !== producthandlerId) {
ctx.removeClass('active');
$("#" + producthandlerId + "box").slideUp(1000);
}
});
});
});

Keeping buttons in place when using .hide()

Not sure if this is because I'm new to meteor or if I am making an error in my syntax with my HTML or jQuery. Ideally I would like the whole grid to stay in place when a button is clicked. For example if you clicked the button in the middle of the grid there would be a empty spot where that button was before. My question is, why is it that when I click a button the button disappears but moves the whole grid and what do I do to fix this?
HTML:
<head>
<title>bubblepopper</title>
</head>
<body>
<center>{{> grid}}</center>
</body>
<template name ="grid">
<div id="container">
{{#each buttons}}
<button class="button" type="button"></button>
{{/each}}
</div>
</template>
JS:
Buttons = new Meteor.Collection("buttons");
if (Meteor.isClient) {
player = prompt("What is your name?")
Template.grid.buttons = function () {
}
Template.grid.buttons = function () {
var list = [];
for(var i=1; i<=64; i++){
list.push({value: i});
}
return list;
};
Template.grid.events({
'click .button': function(ev) {
$(ev.target).hide()
}
});
}
if (Meteor.isServer) {
}

.hide() works by adding the style display: none to the element. This removes the space used by the element in the rendered page.
If you want to make something invisible but keep its space on the page, use the visibility style:
$(ev.target).css('visibility', 'hidden');
To restore it, set the visibility to visible.

Show div once clicked and hide when clicking outside

I'm trying to show the #subscribe-pop div once a link is clicked and hide it when clicking anywhere outside it. I can get it to show and hide if I change the:
$('document').click(function() {
TO
$('#SomeOtherRandomDiv').click(function() {
HTML:
<div id="footleft">
Click here to show div
<div id="subscribe-pop"><p>my content</p></div>
</div>
Script:
<script type="text/javascript">
function toggle_visibility(id) {
var e = document.getElementById("subscribe-pop");
if(e.style.display == 'block')
e.style.display = 'none';
else
e.style.display = 'block';
}
}
$('document').click(function() {
$('#subscribe-pop').hide(); //Hide the menus if visible
});
$('#subscribe-pop').click(function(e){
e.stopPropagation();
});
</script>

You have to stop the event propagation in your container ('footleft' in this case), so the parent element don't notice the event was triggered.
Something like this:
HTML
<div id="footleft">
<a href="#" id='link'>Click here to show div</a>
<div id="subscribe-pop"><p>my content</p></div>
</div>
JS
$('html').click(function() {
$('#subscribe-pop').hide();
})
$('#footleft').click(function(e){
e.stopPropagation();
});
$('#link').click(function(e) {
$('#subscribe-pop').toggle();
});
See it working here.

I reckon that the asker is trying to accomplish a jquery modal type of display of a div.
Should you like to check this link out, the page upon load displays a modal div that drives your eye into the center of the screen because it dims the background.
Moreover, I compiled a short jsFiddle for you to check on. if you are allowed to use jquery with your requirements, you can also check out their site.
Here is the code for showing or hiding your pop-up div
var toggleVisibility = function (){
if($('#subscribe-pop').is(":not(:visible)") ){
$('#subscribe-pop').show();
}else{
$('#subscribe-pop').hide();
}
}

Changing $(document).click() to $('html').click() should solve the main problem.
Secondly, you do not need the toggle_visibility() function at all, you can simply do:
$('#subscribe-pop').toggle();

jQuery conditionally change events depending on .html( 'string' ) values

Please feel free to change the heading if you think I've worded it wrong.
General
I'm running a wordpress site with multilingual control. And my menu/navigation is dynamic, controlled via the wordpress admin. The multilingual language plugin also changes the dynamic menu/navigation content, as well as page content.
My Contact button, which is in the dynamic navigation, opens a sliding menu using jQuery. Very simple animation using top css. The contact button is on the page twice, hence why I'm not using the .toggle for iterations. See jsFiddle.
Script
var $button = $(".contact-button"),
// var for button which controls sliding div
$slide = $("#content-slide");
// var for the div which slides up and down
$button.on('click', function () {
// function for when button is clicked
if ($button.html() == 'Close') {
// run this if button says 'Close'
$slide.stop().animate({ top: "-269px" }, 300);
// close slide animation
$button.html('Contact');
// change text back to 'Contact'
} else {
// else if button says Contact or anything else
$slide.stop().animate({ top: "0" }, 300);
// open slide animation
$button.html('Close');
// change text to 'Close'
}
});
Problem
Because I'm running multilingual on the site. The navigation spelling changes. See jsFiddle flag buttons for example. This is fine, the animation still runs OK, because it's using the button class 'contact-button'.
But because I'm using the .html to replace the text of the button to "Close" and then on the second iteration, back to "Contact" - obviously this is a problem for other languages, as it always changes to English 'close' and back to English 'Contact'
But my three languages and words that I need the iterations to run through are...
Contact - Close
Contatto - Cerca
Contacto - Chiudere
Can anyone help me expand my script to accommodate three languages, all my attempts have failed. The jsFiddle has the script.
The language functionality in the fiddle is only for demo purposes, so the iteration sequence can be tested from the beginning. I understand if you change the language whilst the menu is open (in the fiddle), it will confused it. But when the language is changed on my site, the whole page refreshes, which closes the slide and resets the sequence. So it does not matter.
Any pro help would be awesome thanks!!!
MY POOR ATTEMPT, BUT YOU CAN SEE WHAT I'M TRYING TO ACHIEVE
var $button = $(".contact-button"),
// Var for button which controls sliding div
$slide = $("#content-slide");
// Var for the div which slides up and down
$button.on('click', function () {
// function for when button is clicked
if ($button.html() == 'Close' || 'Cerca'|| 'Chiudere' ) {
// run this if button says Close or Cerca or Chiudere
$slide.stop().animate({ top: "-269px" }, 300);
// Close slide animation
$(function () {
if ($button.html(== 'Close') {
$button.html('Contact'); }
else if ($button.html(== 'Cerca') {
$button.html('Contatto'); }
else ($button.html(== 'Chiudere') {
$button.html('Contacto'); }
});
// Change text back to Contact in correct language
} else {
// else if button says Contact or anything else
$slide.stop().animate({ top: "0" }, 300);
// Open slide animation
$(function () {
if ($button.html(== 'Contact') {
$button.html('Close'); }
else if ($button.html(== 'Contatto') {
$button.html('Cerca'); }
else ($button.html(== 'Contacto') {
$button.html('Chiudere'); }
});
// Change text back to Close in the correct language
}
});
See my attempt script above which is not working on this jsFiddle.

Here's a working example: http://jsfiddle.net/Qh8fL/2/
When one of the language buttons gets clicked, it stores the strings for Contact and Close using jQuery's .data() method. Then, when the contact/close button gets clicked, it refers to those strings rather than having it hard-coded.
Here are the relevant lines of code:
$("#english").click(function() {
$(".contact-button").html('Contact').data('langTxt',{contact:'Contact',close:'Close'});
});
$("#spanish").click(function() {
$(".contact-button").html('Contatto').data('langTxt',{contact:'Contatto',close:'Close'});
});
$("#italian").click(function() {
$(".contact-button").html('Contacto').data('langTxt',{contact:'Contacto',close:'Close'});
});
if ($button.html() == 'Close') {
//...
$button.html($button.data('langTxt').contact);
} else {
//...
$button.html($button.data('langTxt').close);
}
All you need to do to modify the "close" text appropriately is by editing the close property inside the calls to data() that occur in each of the click events.

You should never depend on label strings ... especially in a multilingual environment. Instead you should use placeholders that you store in an attribute (maybe using .data()). Then you write your own setters for the labels depending on the value of the attribute.
var myLabels = {'close': ['Close', 'Cerca', 'Chiudere'], 'contact' : ['Contact', 'Contatto', 'Contacto']};
var currLang = 2; // to select italian
....
// to set the label
$button.data('mylabel', 'close');
$button.html(myLabels['close'][currLang]);
....
if($button.data('mylabel') == 'close') {
$button.data('mylabel', 'contact');
$button.html(myLabels['contact'][currLang]);
} else {
$button.data('mylabel', 'close');
$button.html(myLabels['close'][currLang]);
}
