Javascript: how to function if class exists or change

Thank you, everyone!
I am keep going design my game with Javascript.
There is box, id called 'box1'.
Also, there is a hidden button.
I have a function to change the box1 class.
I want to change the visibility if the box1 has the class "glow".
In fact, I am planning to check 9 boxes class. Therefore, I may use && for "if" condition.
$(document).ready(function() {
if (document.$('#box1').classList.contains('.glow')) {
$(".btn-warning").css('visibility', 'visible');
}});

something like you can design your code
You have a 9 blocks with its like box1, box2, so on
Loops through get all class nodes
$("div[id^='box']").foreach(function(){
if($(this).hasClass(".glow"))
{
// your logic
$(".btn-warning").css('visibility', 'visible');
}
}
I hope this will work for you

Thank you everyone for your comments.
I change my logic.
I finish the code myself.
gameboxsize is the div for 9boxes.
setInterval(function() {
var gamebox = document.getElementById('gameboxsize');
var nodesSameClass = gamebox.getElementsByClassName('glow');
console.log(nodesSameClass.length);
var winNum = nodesSameClass.length;
if (winNum === 9) {
$(".btn-warning").css('visibility', 'visible');
}
});

change div with Javascript

With pure Javascript I want to create a tab effect to toggle content in a div. Content is the name of the class I want to add or remove the second class active from
<script>
function changeClass(element) {
if (classList !=='active') {
element.classList.add('active');
}
else { element.classList.remove('active'); }
}
</script>
<ul>
<li onclick = "changeClass("content")">

The error is that you're not selecting any elements (wonder why nobody caught this), but trying to change the classlist of a string ("content".classList...). Make sure you select the proper element first:
function changeClass(element) {
element = document.getElementsByClassName(element)[0]; // assuming here we're selecting the first one
if (!element.classList.contains('active')) { // had to fix this as variable classList wasn't defined
element.classList.add('active');
}
else {
element.classList.remove('active');
}
}
Also, as #Teemu suggested in comments, but refused to write it, feel free to use element.classList.toggle('active');.
So the whole code should be:
function changeClass(element) {
element = document.getElementsByClassName(element)[0]; // assuming here we're selecting the first one
element.classList.toggle('active');
}

If you want to simply toggle between two classes, you can do something like this:
function changeClass(element) {
element.classList.toggle('Content');
}
Though in this case you've to pass a reference to the element rather than it's className.

Appending hash/subpage to URL when loading content in expanding divs

I'm loading in separate .html documents inside divs with this code:
JS
$('.thumbnail').click(function() {
var idStr = ("project/"+$(this).attr('id')) + " #projectcontainer";
$('#projectcontainer').animate({opacity:0});
$('#projectcontainer').hide().load(idStr,function(){
$(this).slideDown(500).animate({opacity:1}, function() {
$.scrollTo('#gohere',800);
$('#close').fadeIn(500).css({'display': 'block', 'height': '25px'});
});
});
});
HTML
<div class="thumbnail" id="atmotype.html">
<img src="image.whatever">
</div>
It all works as intended but I also wanna append an ID when you open a project, and also be able to link directly to said content (already expanded in the div). I've been trying around and can't come up with a solution, and that being said I'm pretty awful with JS in general.
Would really appreciate if someone could enlighten me on how this works.

Right now when you click your .thumbnail element, it is firing your click() event and using $(this).attr('id') for the hash/scroll. To make this run when the page load, you should probably break it out to a separate function that takes the ID as a parameter, and then call this function from your click() event as well as a generic page load using a parameter in location.hash.
$(document).ready(function(){
if (location.hash.length>0){
/* this assumes the page to load is the only thing in the
hash, for example /page.php#project.html */
var hash = location.hash.substring(1); // get hash and remove #
addHashAndScroll(hash); // call function with page name
}
$('.thumbnail').click(function() {
addHashAndScroll($(this).attr('id')); // pass ID value to function
});
}
// this function contains most of your original script
function addHashAndScroll(id){
var idStr = "project/"+ id + "#projectcontainer";
// rest of your code
}
UPDATE:
This is the thing about js it all makes sense when explained but executing it is a bitch. Anyways thanks alot for helping out. Based on your explanation what I get is:
$(document).ready(function() {
if (location.hash.length > 0) {
/* this assumes the page to load is the only thing in the
hash, for example /page.php#project.html */
var hash = location.hash.substring(1); // get hash and remove #
addHashAndScroll(hash); // call function with page name
}
$('.thumbnail').click(function() {
addHashAndScroll($(this).attr('id')); // pass ID value to function
});
}
// this function contains most of your original script
function addHashAndScroll(id) {
var idStr = "project/" + id + "#projectcontainer";
$('#projectcontainer').animate({
opacity: 0
});
$('#projectcontainer').hide().load(idStr, function() {
$(this).slideDown(500).animate({
opacity: 1
}, function() {
$.scrollTo('#gohere', 800);
$('#close').fadeIn(500).css({
'display': 'block',
'height': '25px'
});
});
});
}
I've tried to fiddle around with the closures and whatever minimal experience i have in bug testing js but i keep getting errors originating from this line:
function addHashAndScroll(id) {

Dynamically added input box problem?

I have dynamically added div.In which i have text box.While adding dynamic div i can put a value to the current div but not the previously open divs. I want to ask how to add Value to the previously open text boxes of Div.
Thank You

here is a solution that refresh ALL. (I don't understand the "previously open text box" part of your question. Well I understand it, but it doesn't show in your code. I assume the "rhythm" column of your table is an input/textarea html element (since you use it's value).
Please note I'm not sure what the vitalset function is supposed to accomplish, or what "vitals_form_readings_1_rhythm" is.
function queryDb(statement)
{
dbQuery = new air.SQLStatement();
dbQuery.sqlConnection = db;
dbQuery.text = statement //"SELECT * FROM rhythm";
//alert(dbQuery.text);
try {
dbQuery.execute();
} catch (error) {
air.trace("Error retrieving notes from DB:", error);
air.trace(error.message);
return;
}
return (dbQuery.getResult());
}
function crhythm()
{
var statement = "SELECT * FROM rhythm";
return queryDb(statement)
}
function reading_speedcode()
{
if (!cvitals) {
var crhythms = crhythm();
var i=0;
$(crhythms).each( function () {
crhythm = this.crhythm;
var pr = 'card_' + i;
$('#rhythm1').append('<br/><td class="content_big" id="'+pr+'" name="'+pr+'">' + crhythm + ' </td>');
i++
});
}
});
$(document).ready( function () {
reading_speedcode();
$('#rhythm1 .content_big').live('click', function(event) {
$('#rhythm1').empty()
reading_speedcode();
});
});
now, there are several things about your code.
variable naming. (for god sake use meaningful names!)
reading full table when you need one row
where is cvitals declared or assigned?
string parsing. Jquery is good at working with set of elements, there should be no need to parse "pr" to recover the row number.
if a value is inserted in rhythm table (or deleted) before your click, the vitalset logic fails. you might want to use the table id instead.
make sure "#vitals_form_readings_1_rhythm" is unique, not retrieved from the table.
if you can answer my question from the top of this post(vitalset function, vitals_form_readings_1_rhythm, cvitals) I will try improve the code.

Passing parameter to css :not selector

I have a function to hide all divs on the page except one div.
// hide all div exceept div1
function hideAllExcept()
{
$('div:not(#div1)').slideUp(800);
}
or
// hide all div exceept 'thisdiv'
function hideAllExcept()
{
$('div:not("#div1")').slideUp(800);
}
The above works fine (difference is first function doesn't have "" around #div1). However, I would like to pass a parameter in the hideAllExcept function to dynamically specify which div to not hide. So I changed the function to:
// hide all div exceept 'thisdiv'
function hideAllExcept(thisdiv)
{
$('div:not(thisdiv)').slideUp(800);
}
if i call the function using: hideAllExcept('#div1') or hideAllExcept("#div1") it doesn't work. It seems that $('div:not(thisdiv)') still selects all divs, it doesn't exclude thisdiv.
Any ideas? Many thanks

Change it to:
function hideAllExcept(thisdiv) {
$('div:not('+thisdiv+')').slideUp(800);
}

$('div').not(thisdiv).slideUp(800);

var divid='div:not('+thisdiv+')';
$(divid).slideUp(800);
