How do I edit the text of a button when the content is displayed/actively showing?

Using this example:
$('[data-switch]').on('click', function(e)
{
var
$page = $('#page-2')
, blockToShow = e.currentTarget.getAttribute('data-switch')
;
// Hide all children.
$page.children().hide();
// And show the requested component.
$page.children(blockToShow).show();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button data-switch="#about_me">Click to read about me</button>
<button data-switch="#education">Click to show my education</button>
<button data-switch="#about_name_bravitus">Click to read about the name Bravitus</button>
<div id="page-2">
<div id="about_me" class="container">
<h1>This is about me section</h1>
<div>about me about me about me</div>
</div>
<!-- Hidden blocks that you show when requested. -->
<div id="education" class="container" style="display: none;">
<h1>This is about my education</h1>
<div>education education education</div>
</div>
<div id="about_name_bravitus" class="container" style="display: none;">
<h1>This is about the name bravitus</h1>
<div>bravitus bravitus bravitus</div>
</div>
</div>
How would one go about changing the font color and weight of the button text when the content is being displayed (not based on when the button is clicked)?
I have tried to find posts with a similar request, but I am greatly struggling. Any direction would be appreciated.

There is many ways to do that, like this one :
const
btns_Switch = document.querySelectorAll('[data-switch]')
, page2_parent = document.querySelector('#page-2')
;
btns_Switch.forEach( btn =>
{
btn.onclick = e =>
{
page2_parent.dataset.switch = btn.dataset.switch;
setButtonActive();
}
})
setButtonActive(); // init on page load...
function setButtonActive()
{
let activBtn = page2_parent.dataset.switch;
btns_Switch.forEach( btn =>
btn.classList.toggle('active', activBtn === btn.dataset.switch ))
}
#page-2[data-switch="about_me"] > div:not(#about_me) ,
#page-2[data-switch="education"] > div:not(#education) ,
#page-2[data-switch="about_name_bravitus"] > div:not(#about_name_bravitus)
{
display : none;
}
button.active
{
background : yellow;
font-weight : bold;
}
<button data-switch="about_me">Click to read about me</button>
<button data-switch="education">Click to show my education</button>
<button data-switch="about_name_bravitus">Click to read about the name Bravitus</button>
<div id="page-2" data-switch="education" > <!-- set initial ID value -->
<div id="about_me" class="container">
<h1>This is about me section</h1>
<div>about me about me about me</div>
</div>
<div id="education" class="container" >
<h1>This is about my education</h1>
<div>education education education</div>
</div>
<div id="about_name_bravitus" class="container" >
<h1>This is about the name bravitus</h1>
<div>bravitus bravitus bravitus</div>
</div>
</div>

Show/Hide the same div and close all other divs

I am trying to write a code when click on the link it toggleSlide the relevant div and hide all other divs. But the issue I am facing, when I click to close same div then it reopens.
jQuery(document).ready(function($){
var facetTitle = $('.facetwp-facet-title');
facetTitle.on('click', facetAccordian);
// Facet Accordian Function
function facetAccordian(){
var _this = $(this);
$(".filters-holder .facetwp-facet-title").removeClass("opened");
$(".filters-holder .facetwp-facet").slideUp("opened");
var filters = _this.parent().find('.facetwp-facet');
_this.toggleClass('opened');
filters.slideToggle();
}
});
.facetwp-facet {
display:none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="filters-holder">
<div class="fl-col">
<div class="facetwp-bb-module">
<h4 class="facetwp-facet-title">Type</h4>
<div class="facetwp-facet">
Content Here
</div>
</div>
</div>
<div class="fl-col">
<div class="facetwp-bb-module">
<h4 class="facetwp-facet-title">Size</h4>
<div class="facetwp-facet">
Content Here
</div>
</div>
</div>
</div>

Basic we have to check if the one you click on already is "opened"
var opened = _this.hasClass("opened");
Then we can use that to determent if we shall toggle the class or not.
if (!opened) {
_this.toggleClass('opened');
filters.slideToggle();
}
Demo
jQuery(document).ready(function($) {
var facetTitle = $('.facetwp-facet-title');
facetTitle.on('click', facetAccordian);
// Facet Accordian Function
function facetAccordian() {
var _this = $(this);
var n = _this.hasClass("opened");
$(".filters-holder .facetwp-facet-title").removeClass("opened");
$(".filters-holder .facetwp-facet").slideUp("opened");
var filters = _this.parent().find('.facetwp-facet');
if (!n) {
_this.toggleClass('opened');
filters.slideToggle();
}
}
});
.facetwp-facet {
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

Displaying elements based on search

I would like the .box elements to show/hide based on the words the user searches for, so for example if a user types in 'Title2 Title1' because those words exists inside box one and two they will remain visible with the renaming .box elements hiding. All the text within the .box elements needs to be searchable not just that in the .title element.
Below is how far I've got. It's almost there but it's not quite working as hoped.
Any help would be great.
Many thanks.
<input placeholder="Search" id="search" type="text" />
<div class="box">
<div class="title">Box Title1</div>
<div class="content">
Box title one content
</div>
</div>
<div class="box">
<div class="title">Box Title2</div>
<div class="content">
Box title two content
</div>
</div>
<div class="box">
<div class="title">Box Title3</div>
<div class="content">
Box title three content
</div>
</div>
<script>
$("#search").on("input", function () {
var search = $(this).val();
if (search !== "") {
var searchArray = search.split(" ");
searchArray.forEach(function(searchWord) {
$(".box").each(function () {
if($(this).is(':contains('+ searchWord +')')) {
$(this).show();
} else {
$(this).hide();
}
});
});
} else {
$(".box").show();
}
});
</script>

You need to use a different search method. :contains does not work as you expect. Consider the following example.
$(function() {
function filter(e) {
var term = $(e.target).val();
if (term.length < 3) {
$(".box").show();
return;
}
$(".box").each(function(i, el) {
if ($(".content", el).text().indexOf(term) >= 0) {
$(el).show();
} else {
$(el).hide();
}
});
}
$("#search").keyup(filter);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input placeholder="Search" id="search" type="text" />
<div class="box">
<div class="title">Box Title1</div>
<div class="content">Box title one content</div>
</div>
<div class="box">
<div class="title">Box Title2</div>
<div class="content">Box title two content</div>
</div>
<div class="box">
<div class="title">Box Title3</div>
<div class="content">Box title three content</div>
</div>
So for example if on is entered, no filtering is performed. If one is entered, the script will look inside the content class of each box and if one is found in the text, it will be shown otherwise, it is hidden. If the User clears their search out, all items are shown.

Hide all box before iterate, then only show when match any words:
$("#search").on("input", function () {
var search = $(this).val();
if (search !== "") {
var searchArray = search.split(" ");
// Hide all .box
$(".box").each(function () {
$(this).hide();
})
searchArray.forEach(function(searchWord) {
$(".box").each(function () {
if($(this).is(':contains('+ searchWord +')') ) {
$(this).show();
}
});
});
} else {
$(".box").show();
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input placeholder="Search" id="search" type="text" />
<div class="box">
<div class="title">Box Title1</div>
<div class="content">
Box title one content
</div>
</div>
<div class="box">
<div class="title">Box Title2</div>
<div class="content">
Box title two content
</div>
</div>
<div class="box">
<div class="title">Box Title3</div>
<div class="content">
Box title three content
</div>
</div>

Loop through all .boxs and using regex pattern matching, check either the title or content matches the search query. Show all matched boxes and hide all others
I have also fiddled it here
$("#search").on("input", function () {
var searchables=$('.box');
console.log(searchables)
var query=$(this).val();
searchables.each(function(i,item){
var title=$(item).find('.title').text();
var content=$(item).find('.content').text();
var rgx=new RegExp(query,'gi');
if(rgx.test(title) || rgx.test(content))
{
$(item).show();
}
else
{
$(item).hide();
}
})
})

Add and remove active class to multiple ids automatically in loop

Currently have the following HTML:
<div class="wrapper">
<div id="sat0" class="sat"></div>
<div id="sat1" class="sat"></div>
<div id="sat2" class="sat"></div>
<div id="sat3" class="sat"></div>
<div id="sat4" class="sat"></div>
<div id="sat5" class="sat"></div>
<div id="sat6" class="sat"></div>
<div id="sat7" class="sat"></div>
<div id="sat8" class="sat"></div>
<div id="sat9" class="sat"></div>
<div id="sat10" class="sat"></div>
<div id="sat11" class="sat"></div>
</div>
I want the class="active" added to id="sat0" and id="sat6" on page load. Then a second later the active class should be remove from both and be added to the two next ones so id="sat1" and id="sat7". It should loop endlessly, so when gets to id="sat5" and id="sat11" the next would be "id=sat6" and id="sat0".
Currently using the following javascript.
<script>
$(document).ready(function(){
$("#sat0").addClass("active");
$("#sat6").addClass("active");
setTimeout(autoAddClass, 1200);
});
function autoAddClass(){
var next = $(".active").removeClass("active").next();
if(next.length)
$(next).addClass('active');
else
$("#sat0").addClass("active");
$("#sat6").addClass("active");
setTimeout(autoAddClass, 1200);
}
</script>
It acts rather chaotically. Any thoughts?

The main reason you seem to get chaotic behavior is that you're always adding active back to #sat6, because you need to use a block in your else (really, I recommend always using blocks with control-flow statements) so the #sat6 part is conditional:
function autoAddClass(){
var next = $(".active").removeClass("active").next();
if(next.length) {
$(next).addClass('active');
} else {
$("#sat0").addClass("active");
$("#sat6").addClass("active");
}
setTimeout(autoAddClass, 1200);
}
Updated example:
function autoAddClass(){
var next = $(".active").removeClass("active").next();
if(next.length) {
$(next).addClass('active');
} else {
$("#sat0").addClass("active");
$("#sat6").addClass("active");
}
setTimeout(autoAddClass, 1200);
}
autoAddClass();
.active {
background-color: yellow;
}
<div class="wrapper">
<div id="sat0" class="sat">0</div>
<div id="sat1" class="sat">1</div>
<div id="sat2" class="sat">2</div>
<div id="sat3" class="sat">3</div>
<div id="sat4" class="sat">4</div>
<div id="sat5" class="sat">5</div>
<div id="sat6" class="sat">6</div>
<div id="sat7" class="sat">7</div>
<div id="sat8" class="sat">8</div>
<div id="sat9" class="sat">9</div>
<div id="sat10" class="sat">10</div>
<div id="sat11" class="sat">11</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
But another reason would be that the top sequence (starting with #sat0) continues longer than the other; you might want if (next.length == 2) instead of just if (next.length):
function autoAddClass(){
var next = $(".active").removeClass("active").next();
if(next.length == 2) {
$(next).addClass('active');
} else {
$("#sat0").addClass("active");
$("#sat6").addClass("active");
}
setTimeout(autoAddClass, 1200);
}
autoAddClass();
.active {
background-color: yellow;
}
<div class="wrapper">
<div id="sat0" class="sat">0</div>
<div id="sat1" class="sat">1</div>
<div id="sat2" class="sat">2</div>
<div id="sat3" class="sat">3</div>
<div id="sat4" class="sat">4</div>
<div id="sat5" class="sat">5</div>
<div id="sat6" class="sat">6</div>
<div id="sat7" class="sat">7</div>
<div id="sat8" class="sat">8</div>
<div id="sat9" class="sat">9</div>
<div id="sat10" class="sat">10</div>
<div id="sat11" class="sat">11</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
BTW, if you want to make it easier to add/remove divs, you don't need any of those id="..."; just use $(".sat:nth-child(1)") and $(".sat:nth-child(7)") (or if you have other elements in there, $(".sat:eq(0)") and $(".sat:eq(6)")) to start with:
function autoAddClass(){
var next = $(".active").removeClass("active").next();
if(next.length == 2) {
$(next).addClass('active');
} else {
$(".sat:nth-child(1)").addClass("active");
$(".sat:nth-child(7)").addClass("active");
}
setTimeout(autoAddClass, 1200);
}
autoAddClass();
.active {
background-color: yellow;
}
<div class="wrapper">
<div class="sat">0</div>
<div class="sat">1</div>
<div class="sat">2</div>
<div class="sat">3</div>
<div class="sat">4</div>
<div class="sat">5</div>
<div class="sat">6</div>
<div class="sat">7</div>
<div class="sat">8</div>
<div class="sat">9</div>
<div class="sat">10</div>
<div class="sat">11</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
(If you have multiple .wrapper that you're doing this in, you'll have to adjust things a bit to work within them individually...)

on keypress display one div and other should hide

when i press any key i need to display first div "d1" others hide and i press any key again it display secound div "d2" others hide and press any key again it display third div "d3" others hide ..till six div..not repeating the process again.
<div class="objects" id="d1">
<img src="images/d1.jpg" />

<div class="objects" id="d2">
<img src="images/d2.jpg" />
</div>
<div class="objects" id="d3">
<img src="images/d3.jpg" />

<img src="images/d6.jpg" />
</div>
when i press any key i need to display 1st div then i press any key display 2nd div..till 6th div..
how to do it in javascript?

<html>
<head>
<style type="text/css">
.Div
{
display: none;
}
</style>
<script type="text/javascript">
var i = 0;
function KeyHandler() {
i++;
var divs = document.getElementsByClassName("Div");
for (var div = 0; div < divs.length - 1; div++) {
divs[div].style.display = 'none';
}
var ele = document.getElementById("d" + i);
ele.style.display = "block";
}
</script>
</head>
<body onkeyup="KeyHandler()">
Press any key..
<div id="d1" class="Div">
<h5>
Div1</h5>
</div>
<div id="d2" class="Div">
<h5>
Div2</h5>
</div>
<div id="d3" class="Div">
<h5>
Div3</h5>
</div>
<div id="d4" class="Div">
<h5>
Div4</h5>
</div>
<div id="d5" class="Div">
<h5>
Div5</h5>
</div>
<div id="d6" class="Div">
<h5>
Div6</h5>
</div>
</body>
</html>

Try this out
var currentVisible = 0;
document.onkeyup = function() {
// First hide all by class 'objects'
// Requires IE9+ FF3+, others are supported
var objs = document.getElementsByClassName('objects');
for (var i=0; i<objs.length; i++) {
objs[i].style.display = 'none';
}
// Show the one we are supposed to show
if (++currentVisible == 7)
currentVisible = 1;
var el = document.getElementById('d' + currentVisible);
el.style.display = 'block';
}
100% untested tho, since I have no access to any fiddle atm.
