Faking a toggle switch with an Input Range, dealing with custom range

I need to fake a toggle switch with an input range.
The idea is to create a short range, with just 2 values, min and max. the css button will match one end of the range. So far you click on it, the div containing the range will move a bit bringing the other end of the ranger under your mouse.
I have this function, which applies on all input ranges on the page. But i need to apply it only on some classes, not all. But i can't find the right syntax and it doesn't work.
The Javascript:
$('input[type="range"]').on('change', function() {
$('div#launcher01').css('margin-top', parseInt($(this).val() ) > 0 ? parseInt($(this).val() ) + 'px' : '0px');
});
CSS:
.fakbl input {
height: 50px;
width: 50px;
HTML:
<div id="launcher01">
<div class="fakbl">
<input type="range" id="launch01" name="launch01" min="0" max="50" step="50"" />
</div>
</div>
Fiddle

Since you are already using jQuery, you can phrase your widget-maker as a jQuery plugin as follows :
$.fn.rangeButton = function(containerSelector) {
return this.each(function() {
var $self = $(this);
$self.on('change', function() {
$self.closest(containerSelector).css('margin-left', ($self.val()/3) > 0 ? ($self.val()/3) + 'px' : '0px');
}).trigger('change'); // trigger 'change' immediately to initialize everything.
});
};
Now, invoke the widget on each of your ranges, and pass a selector for the appropriate container :
$('#launcher01 input[type="range"]').rangeButton('#launcher01');
$('#launcher02 input[type="range"]').rangeButton('#launcher02');
Demo
Alternatively, by giving all containers the same class, you can invoke all your widgets with a single command :
$('.myClass input[type="range"]').rangeButton('.myClass');
Demo

May I ask a refinement please?
I completed the fake button. As you can see in this FIDDLE
(the white box will disappear, I added some opacity to it just to show that the button is working)
The red box (now green due to my buggy code part) is in the background and I would need it to change color depending on the status. I tried this but it doesn't work.
Here the code:
$.fn.rangeButton = function(containerSelector) {
return this.each(function() {
var $self = $(this);
$self.on('change', function() {
$self.closest(containerSelector).css('margin-left', ($self.val()/3) > 0 ? ($self.val()/3) + 'px' : '0px');
// this part is not working, if you remove this part, the button works flawlessy
if ($self = 100) {
document.getElementById("fakbuttonsfondo01").style.backgroundColor="rgb(0, 191, 1)";
} else {
document.getElementById("fakbuttonsfondo01").style.backgroundColor="rgb(0, 0, 255)";
}
// end of buggy code
}).trigger('change'); // trigger 'change' immediately to initialize everything.
});
};
$('#launcher01 input[type="range"]').rangeButton('#launcher01');
$('#launcher02 input[type="range"]').rangeButton('#launcher02');
Thanks:)

Detect page find/search to expand a collapsible

My team is using an expandable box to condense info on our wiki (in Confluence), it's pretty standard using display:none/block. I'd like this to work with the browser's find functionality. I've found that when I switch to hiding the content using max-height the browser at least finds the text correctly, but I'd like to expand the collapsible when a match is found inside it and re-collapse it when find is no longer looking at it. Is there a way to do that?
I've already tried the focus and selectionchange events to no avail. I guess I could track scrolling for jumps or track keystrokes but neither of those really tells me if the collapsible is where the query was found.
tl;dr is there a way to detect browser find?
Update: Here's an idea of what the code looks like:
var expand = document.querySelector('.expand');
expand.querySelector('.head').addEventListener('click', function(e) {
//toggle a class .show on .expand
})
And my CSS:
.expand .body {
opacity: 0;
max-height: 0;
padding: 0 20px 0 40px;
transition: all .4s;
}
.expand.show .body {
max-height: 3000px;
opacity: 1;
padding: 10px 20px 20px 40px;
}

Actually you can detect key press combination such as Ctrl+F like below
var map = {17: false, 70: false};
$(document).keydown(function(e) {
if (e.keyCode in map) {
map[e.keyCode] = true;
if (map[17] && map[70]){
// FIRE EVENT YOU EVENT
}
}
}).keyup(function(e) {
if (e.keyCode in map) {
map[e.keyCode] = false;
}
});

JQuery or Javascript that will make an element fade away automatically

So I am making a clicker game and am kind of stuck. I want a popup like cookieClicker has when you get an achievement. It pops up and tells you what happened, you can click the x or it will just fade away after a few seconds.
I tried making something with pure javascript and CSS to no avail, it would fade away nicely but not automatically.
So how do I make it so whenever X element is made/displayed then it goes away after 3 seconds?
Also, if it matters the element would be created by a javascript function, and multiples might be created at the same time.
P.S. I tried searching and found something about auto-fading in javascript but nothing in there seemed to work either.
EDIT: After trying to view cookieclicker source and playing the game again it appears it doesn't even have this functionality. The closest thing I can compare it to is when you would add something to your cart on a website, then it alerts you the item was added and then fades away.

Here is one approach which uses Javascript to trigger a CSS transition:
var button = document.getElementsByTagName('button')[0];
var div = document.getElementsByTagName('div')[0];
function autoFader() {
if (window.getComputedStyle(div).getPropertyValue('display') === 'none') {
div.style.display = 'block';
setTimeout(function(){
div.style.opacity = '0';
},10);
setTimeout(function(){
div.removeAttribute('style');
},4010);
}
}
button.addEventListener('click',autoFader,false);
div {
display: none;
width: 200px;
height: 100px;
margin: 20px auto;
padding: 6px;
font-size: 20px;
color: rgb(255,255,255);
text-align: center;
border: 3px solid rgb(127,0,0);
background-color: rgb(255,0,0);
opacity: 1;
transition: opacity 3s linear 1s;
}
<button type="button">Click Me</button>
<div>
<p>Hi, I'm an auto-fading pop-up.</p>
</div>

So, your openPopup function might look like this:
function openPopup(/* options here */) {
const popup = actuallyOpenPopup();
waitSomeTimeAndCloseIfNotClosedYet(popup);
}
where 2nd function should take a popup instance (which has .close method probably, or dismiss)
and start a timeout. You need to keep that timeout, so if close was called, you need to cancel it.
Something like this:
function waitSomeTimeAndCloseIfNotClosedYet(popup) {
const originalClose = popup.close;
/* monkey patching, decorating,
separate method - whatever you prefer */
popup.close = function () {
clearTimeout(this.timeout);
originalClose.call(this);
};
popup.timeout = setTimeout(() => popup.close(), 3000);
}
So, if was closed manually - it wont be called twice, if not, will fire up a timeout and close automatically.
Via CSS you can only achieve visible closing, but not removal of nodes. (Google for transition visibility, fade out modal etc.)
Hope this helps!

Toggling between two different Opacities

I have all 26 letters in the alphabet and I want to make it so that when you click on it will fade to a lower opacity but if you click on it again it will come back to 1.0 opacity. I have not a single clue on how I would go about specifically choosing the letter that was clicked on and I also cant seem to figure out how I would toggle it to a specific opacity.
$(document).ready(function() {
$(".alphabetLetter").click(function(event) {
var x = event.target||event.srcElement;
if(event.target.style.opacity == 1.0){
$(x).fadeTo('slow',0.5);
} else if(event.target.style.opacity == 0.5){
$(x).fadeTo('slow',1.0);
}
});
});

You can select for the currently clicked element by using $(this) inside the click event handler.
$(document).ready(function() {
$(".alphabetLetter").click(function(event) {
if ($(this).css('opacity') == '1')
$(this).animate({'opacity':0})
else
$(this).animate({'opacity':1})
});
});

Here's a full simple example:
HTML:
<p class="alphabet">abcdefghijklmnopqrstuvwxyz</p>
JavaScript:
// Your container
var $wrap = $('p.alphabet');
// Wrap all letters in <span>
$wrap.html(function(){
return $(this).text().replace(/./g, '<span class="letter">$&</span>');
});
// Attach the event
$wrap.find('.letter').click(function(){
var isHidden = $(this).css('opacity') == .5;
$(this).fadeTo(300, isHidden ? 1 : .5);
});
Demo: http://jsbin.com/eyajel/1/edit

The opacity can just be done with css transitions and regular old styles.
The CSS
.letter {
transition: opacity 1s;
color: red;
cursor: pointer;
}
.letter.active {
opacity: 0.2;
}
The Javascript
$('body').on('click', '.letter', function(e){
$(this).toggleClass('active');
});
Here is a JSFiddle as an example. It also includes a way to take a string of letters and turn them into markup that works with this: http://jsfiddle.net/PFjnB/1/

How to disable all div content

I was under the assumption that if I disabled a div, all content got disabled too.
However, the content is grayed but I can still interact with it.
Is there a way to do that? (disable a div and get all content disabled also)

Many of the above answers only work on form elements. A simple way to disable any DIV including its contents is to just disable mouse interaction. For example:
$("#mydiv").addClass("disabledbutton");
CSS
.disabledbutton {
pointer-events: none;
opacity: 0.4;
}
Supplement:
Many commented like these: "This will only disallow mouse events, but the control is still enabled" and "you can still navigate by keyboard". You Could add this code to your script and inputs can't be reached in other ways like keyboard tab. You could change this code to fit your needs.
$([Parent Container]).find('input').each(function () {
$(this).attr('disabled', 'disabled');
});

Use a framework like JQuery to do things like:
function toggleStatus() {
if ($('#toggleElement').is(':checked')) {
$('#idOfTheDIV :input').attr('disabled', true);
} else {
$('#idOfTheDIV :input').removeAttr('disabled');
}
}
Disable And Enable Input Elements In A Div Block Using jQuery should help you!
As of jQuery 1.6, you should use .prop instead of .attr for disabling.

Here is a quick comment for people who don't need a div but just a blockelement. In HTML5 <fieldset disabled="disabled"></fieldset> got the disabled attribute. Every form element in a disabled fieldset is disabled.

I just wanted to mention this extension method for enabling and disabling elements. I think it's a much cleaner way than adding and removing attributes directly.
Then you simply do:
$("div *").disable();

You can use this simple CSS statement to disable events
#my-div {
pointer-events:none;
}

The disabled attribute is not part of the W3C spec for DIV elements, only for form elements.
The jQuery approach suggested by Martin is the only foolproof way you're going to accomplish this.

Wrap the div within the form and fieldset tags:
<form>
<fieldset disabled>
<div>your controls</div>
</fieldset>
</form>

similar to cletu's solution, but i got an error using that solution, this is the workaround:
$('div *').prop('disabled',true);
// or
$('#the_div_id *').prop('disabled',true);
works fine on me

If you wanted to keep the semantics of disabled as follows
<div disabled="disabled"> Your content here </div>
you could add the following CSS
div[disabled=disabled] {
pointer-events: none;
opacity: 0.4;
}
the benefit here is that you're not working with classes on the div that you want to work with

One way to achieve this is by adding the disabled prop to all children of the div. You can achieve this very easily:
$("#myDiv").find("*").prop('disabled', true);
$("#myDiv") finds the div, .find("*") gets you all child nodes in all levels and .prop('disabled', true) disables each one.
This way all content is disabled and you can't click them, tab to them, scroll them, etc. Also, you don't need to add any css classes.

As many answers already clarified disabled is not a DIV attribute. However xHTML means Extensible HTML. It means you can define your own HTML attributes (all Frontend frameworks does that as well). And CSS supports attribute selectors which is [].
Use standard HTML with your defined attribute:
<div disabled>My disabled div</div>
Use CSS:
div[disabled] {
opacity: 0.6;
pointer-events: none;
}
NOTE: you can use CSS attribute selector with ID or Class names as well e.g. .myDiv[disabled] {...} Also can apply value filter e.g.: following HTML disabling standard attribute with value div[disabled=disabled] {...}.

Browsers tested: IE 9, Chrome, Firefox and jquery-1.7.1.min.js
$(document).ready(function () {
$('#chkDisableEnableElements').change(function () {
if ($('#chkDisableEnableElements').is(':checked')) {
enableElements($('#divDifferentElements').children());
}
else {
disableElements($('#divDifferentElements').children());
}
});
});
function disableElements(el) {
for (var i = 0; i < el.length; i++) {
el[i].disabled = true;
disableElements(el[i].children);
}
}
function enableElements(el) {
for (var i = 0; i < el.length; i++) {
el[i].disabled = false;
enableElements(el[i].children);
}
}

HTML input controls can be disabled using 'disabled' attribute as you know. Once 'disabled' attribute for an input control is set, event handlers associated with such control are not invoked.
You have to simulate above behavior for HTML elements that don't support 'disabled' attribute like div, if you wish.
If you have a div, and you want to support click or a key event on that div, then you have to do two things:
1) When you want to disable the div, set its disabled attribute as usual (just to comply with the convention)
2) In your div's click and/or key handlers, check if disabled attribute is set on the div. If it is, then just disregard the click or key event (e.g. just return immediately). If disabled attribute is not set, then do your div's click and/or key event logic.
Above steps are browser independent as well.

How to disable the contents of a <div/>
The CSS pointer-events property alone doesn't disable child elements from scrolling, and it's not supported by IE10 and under for <div/> elements (only for SVG).
http://caniuse.com/#feat=pointer-events
To disable the contents of a <div/> on all browsers.
Jquery:
$("#myDiv")
.addClass("disable")
.click(function () {
return false;
});
CSS:
.disable {
opacity: 0.4;
}
/* Disable scrolling on child elements */
.disable div,
.disable textarea {
overflow: hidden;
}
To disable the contents of a <div/> on all browsers, except IE10 and under.
Jquery:
$("#myDiv").addClass("disable");
CSS:
.disable {
/* Note: pointer-events not supported by IE10 and under */
pointer-events: none;
opacity: 0.4;
}
/* Disable scrolling on child elements */
.disable div,
.disable textarea {
overflow: hidden;
}

This is for the searchers,
The best I did is,
$('#myDiv *').attr("disabled", true);
$('#myDiv *').fadeTo('slow', .6);

As mentioned in comments, you are still able to access element by navigating between elements by using tab key. so I recommend this :
$("#mydiv")
.css({"pointer-events" : "none" , "opacity" : "0.4"})
.attr("tabindex" , "-1");

Or just use css and a "disabled" class.
Note: don't use the disabled attribute.
No need to mess with jQuery on/off.
This is much easier and works cross browser:
.disabled{
position: relative;
}
.disabled:after{
content: "";
position: absolute;
width: 100%;
height: inherit;
background-color: rgba(0,0,0,0.1);
top: 0;
left: 0;
right: 0;
bottom: 0;
}
Then you can shut it on and off when initializing your page, or toggling a button
if(myDiv !== "can be edited"){
$('div').removeClass('disabled');
} else{
$('div').addClass('disabled');
}

I thought I'd chip in a couple of notes.
< div > can be disabled in IE8/9. I assume this is "incorrect", and it threw me off
Don't use .removeProp(), as it has a permanent effect on the element. Use .prop("disabled", false) instead
$("#myDiv").filter("input,textarea,select,button").prop("disabled", true) is more explicit and will catch some form elements you would miss with :input

I would use an improved version of Cletus' function:
$.fn.disable = function() {
return this.each(function() {
if (typeof this.disabled != "undefined") {
$(this).data('jquery.disabled', this.disabled);
this.disabled = true;
}
});
};
$.fn.enable = function() {
return this.each(function() {
if (typeof this.disabled != "undefined") {
this.disabled = $(this).data('jquery.disabled');
}
});
};
Which stores the original 'disabled' property of the element.
$('#myDiv *').disable();

Below is a more comprehensive solution to masking divs enabling
no separate CSS
cover the whole page or just an element
specify mask color and opacity
specify Z-index so you can show popups over the mask
show an hourglass cursor over the mask
removing the masking div on maksOff so a different one can be shown later
stretch mask when element resize
return the mask element so you can style it etc
Also included is hourglassOn and hourglassOff which can be used separately
// elemOrId - jquery element or element id, defaults to $('<body>')'
// settings.color defaults to 'transparent'
// settings.opacity defaults to 1
// settings.zIndex defaults to 2147483647
// if settings.hourglasss==true change cursor to hourglass over mask
function maskOn(elemOrId, settings) {
var elem=elemFromParam(elemOrId);
if (!elem) return;
var maskDiv=elem.data('maskDiv');
if (!maskDiv) {
maskDiv=$('<div style="position:fixed;display:inline"></div>');
$('body').append(maskDiv);
elem.data('maskDiv', maskDiv);
}
if (typeof settings==='undefined' || settings===null) settings={};
if (typeof settings.color==='undefined' || settings.color===null) settings.color='transparent';
if (typeof settings.opacity==='undefined' || settings.opacity===null) settings.opacity=1;
if (typeof settings.zIndex==='undefined' || settings.zIndex===null) settings.zIndex=2147483647;
if (typeof settings.hourglass==='undefined' || settings.hourglass===null) settings.hourglass=false;
// stretch maskdiv over elem
var offsetParent = elem.offsetParent();
var widthPercents=elem.outerWidth()*100/offsetParent.outerWidth()+'%';
var heightPercents=elem.outerHeight()*100/offsetParent.outerHeight()+'%';
maskDiv.width(widthPercents);
maskDiv.height(heightPercents);
maskDiv.offset($(elem).offset());
// set styles
maskDiv[0].style.backgroundColor = settings.color;
maskDiv[0].style.opacity = settings.opacity;
maskDiv[0].style.zIndex = settings.zIndex;
if (settings.hourglass) hourglassOn(maskDiv);
return maskDiv;
}
// elemOrId - jquery element or element id, defaults to $('<body>')'
function maskOff(elemOrId) {
var elem=elemFromParam(elemOrId);
if (!elem) return;
var maskDiv=elem.data('maskDiv');
if (!maskDiv) {
console.log('maskOff no mask !');
return;
}
elem.removeData('maskDiv');
maskDiv.remove();
}
// elemOrId - jquery element or element id, defaults to $('<body>')'
// if decendents is true also shows hourglass over decendents of elemOrId, defaults to true
function hourglassOn(elemOrId, decendents) {
var elem=elemFromParam(elemOrId);
if (!elem) return;
if (typeof decendents==='undefined' || decendents===null) decendents=true;
if ($('style:contains("hourGlass")').length < 1) $('<style>').text('.hourGlass { cursor: wait !important; }').appendTo('head');
if ($('style:contains("hourGlassWithDecendents")').length < 1) $('<style>').text('.hourGlassWithDecendents, .hourGlassWithDecendents * { cursor: wait !important; }').appendTo('head');
elem.addClass(decendents ? 'hourGlassWithDecendents' : 'hourGlass');
}
// elemOrId - jquery element or element id, defaults to $('<body>')'
function hourglassOff(elemOrId) {
var elem=elemFromParam(elemOrId);
if (!elem) return;
elem.removeClass('hourGlass');
elem.removeClass('hourGlassWithDecendents');
}
function elemFromParam(elemOrId) {
var elem;
if (typeof elemOrId==='undefined' || elemOrId===null)
elem=$('body');
else if (typeof elemOrId === 'string' || elemOrId instanceof String)
elem=$('#'+elemOrId);
else
elem=$(elemOrId);
if (!elem || elem.length===0) {
console.log('elemFromParam no element !');
return null;
}
return elem;
}
With this you can do for example:
maskOn(); // transparent page mask
maskOn(null, {color:'gray', opacity:0.8}); // gray page mask with opacity
maskOff(); // remove page mask
maskOn(div); // transparent div mask
maskOn(divId, {color:'gray', hourglass:true}); // gray div mask with hourglass
maskOff(div); // remove div mask
see jsfiddle

function disableItems(divSelector){
var disableInputs = $(divSelector).find(":input").not("[disabled]");
disableInputs.attr("data-reenable", true);
disableInputs.attr("disabled", true);
}
function reEnableItems(divSelector){
var reenableInputs = $(divSelector).find("[data-reenable]");
reenableInputs.removeAttr("disabled");
reenableInputs.removeAttr("data-reenable");
}

Another way, in jQuery, would be to get the inner height, inner width and positioning of the containing DIV, and simply overlay another DIV, transparent, over the top the same size. This will work on all elements inside that container, instead of only the inputs.
Remember though, with JS disabled, you'll still be able to use the DIVs inputs/content. The same goes with the above answers too.

$("#yourdivid textarea, #yourdivid input, #yourdivid select").attr('disabled',true);

This css only/noscript solution adds an overlay above a fieldset (or a div or any other element), preventing interaction:
fieldset { position: relative; }
fieldset[disabled]::after { content: ''; display: inline-block; position: absolute; top: 0; left: 0; right: 0; bottom: 0; pointer-events: all; background: rgba(128,128,128,0.2); }
If you want an invisible i.e. transparent overlay, set the background to e.g. rgba(128,128,128,0), as it won't work without a background.
The above works for IE9+. The following much simpler css will work on IE11+
[disabled] { pointer-events: none; }
Chrome

If you are simply trying to stop people clicking and are not horrifically worried about security - I have found an absolute placed div with a z-index of 99999 sorts it fine. You can't click or access any of the content because the div is placed over it. Might be a bit simpler and is a CSS only solution until you need to remove it.

Its very easy to handle if you want to disable the pointer event
document.getElementById("appliedDatepicker").style.pointerEvents = "none";
or
if you want to enable,
document.getElementById("appliedDatepicker").style.pointerEvents = "auto";

EDIT:
Below I've used .on() method, instead use .bind() method
$(this).bind('click', false);
$(this).bind('contextmenu', false);
to remove your setting, you can use .unbind() method. Whereas the .off() method doesn't work as expected.
$(this).unbind('click', false);
$(this).unbind('contextmenu', false);
After researching hundreds of solutions! learning about pointer-events, below is what I did.
As #Kokodoko mentioned in his solution which is apt for all browsers except IE. pointer-events work in IE11 and not in the lower versions. I also noticed in IE11, pointer-events do not work on the child elements. And hence if we have something like below
<i class="car icon"></i><span>My Blog</span>
where span -is the child element, setting pointer-events: nonewont work
To overcome this problem I wrote a function which could act as pointer-events for IE and will work in the lower versions.
In JS File
DisablePointerEvents(".DisablePointerEvents");
function DisablePointerEvents(classId) {
$(classId).each(function () {
$(this).on('click', false );
$(this).on('contextmenu', false );
});
}
In CSS File
.DisablePointerEvents{
pointer-events: none;
opacity: 0.7;
cursor: default;
}
In HTML
<i class="car icon"></i><span>My Blog</span>
This faked the pointer-events scenario where pointer-events doesnt work and when the above condition of child elements occur.

There are configurable javascript libraries that take in a html string or dom element and strip out undesired tags and attributes. These are known as html sanitizers. For example:
DOMPurify
Insane
sanitize-html
E.g. In DOMPurify
DOMPurify.sanitize('<div>abc<iframe//src=jAva&Tab;script:alert(3)>def</div>');
// becomes <div>abcdef</div>
