When i grab object and try to drop in div it doesn't work,no errors in console nothing,logically i have everything done well and i realize what i am doing but in this case i'm stuck.
being a beginner surely is tough,i'm pretty sure i have done some silly mistake in my code.i did easily dropping 1 instance of object in div,but dropping multiple instances sure is another hardcore.

here's a simple representation of a problem I have. When you click on the button, all black divs should change to black. But the big one styled with css doesn't. Any ideas? thanks a lot.
var v;
function link() {
v = document.querySelectorAll('[style*="background:black;"]');
v.forEach(function(value) {
value.style.backgroundColor = "red";
});
}
.box1 {
background-color: black;
height: 200px;
width: 200px;
border: 2px solid green;
font-size: 25px;
color: white;
}

<div class="box1"> css styled box</div>

Try this
var v;
function link(){

v.forEach(function(value){
value.style.backgroundColor = "red";
});

I want to let user go to some website when he clicked my website background picture(parent div), but the function need be closed when user clicked my website content(child div), and then when user clicked the background picture(parent div) again, the function will be activity.
I try many times, but when I clicked my website content(child div), and clicked website background picture(parent div) again, the function didn't work.
What can I do? Thank you!
Here is my code:

}
</style>
<script type="text/javascript">
function bgADlink(){
window.open('https://www.google.com');
}
var i = 0;
function test1(){
if(i == 0 || i == 1)
bgADlink();
return i = 0;
}
function test2(){
bgADlink=false;
return i = 1;
}
</script>
</head>
<body style="margin:0px; background-color:#eeeeee;">
<div class="head">Test</div>
<div class="tt" onclick="test1()">
<div class="content" onclick="test2()"></div>
</div>
</body>
</html>
just remove that || i == 1 condition from test1() function like below.
function test1(){
if(i == 0)
bgADlink();
return i = 0;
}

I am not sure that is what you need, but basically you need to stop event bubbling from child to parent.

There are different problems in your code.
Because events propagate from an inner element, to it's parent element (not only parent but all the hierarchy up), the "tt" div will always fire, so the best thing to do is to stop the propagation of the events with
onclick="event.stopPropagation();test1()"
I don't really understand what you're trying to accomplish with the "i" and why your having a function bgADlink() and then assigning it a Boolean, JavaScript lets you do that, but basically your function is now a Boolean.
I made you a small sample fiddler yo you can see the stopPropagation working, hope it helps.

I am having issues coding a chat box program for a school project. I am having 3 problems with the program. First, my chat message does not post properly in my chat box. Secondly, I want to be able to click exit and have it close to window but am not completely sure how to do it. Lastly, I would like the chat to echo the message or to have ahard coded response at the least. I'm researching how to do that I'm not quite sure how to do this. I have a style sheet and html. Here is my html:

.welcome {

.logout {
float:right; }
.msgln {
margin:0 0 2px 0; }
Some of the css is unnecessary I'm pretty sure but when I tried taking some out it caused issues. Any help is greatly appreciated.
try copying the following - i put the styling into the head, moved the javascript to the end, and swapped the input for a button. This is ties to the onclick and appends the new comment into the chat window. It works, but could be done better, also I have not addressed the issue of closing the window, but this does post the new comment into the chat region.

one problem is that you are using a form that then posts to the same page - reloading it.
I copied your code into a testpage (called chatTest.html) and got the following url after hitting the send button:
chatTest.html?usermsg=test+message&submitmsg=Send
your message does get posted into the chat section but is then removed when the page reloads. and because you are not specifying a method - it is treating it as a get form and posting the message as a querystring appended to the url.
if you are planning on saving the comments to a database, then you should change the action of the form to a different php page, process the results and return the saved content into the chat section- perhaps using Ajax so that you don;t have to reload the page on every chat submission.
When I hover my mouse over a div with id one, dialog box appears, but the div with id three moves to the right.
I want the dialog box to appear over div with id three without it moving to right.

You need a wrapper to position the dialogboxes against:
<div class="wrapper">
<div id="one"></div>
<div id="dialogone"></div>
</div>
Then you'll need to position the wrapper relatively, and position them to your liking (eg. with float). The dialog can be positioned absolutely, for example: position: absolute; left: 100% to position them just outside the wrapper to the right.

How would i get it too loop?
Also, if you see anything wrong with the general code it would be appreciated if you point it out! I am new to Jquery, JS and HTML/CSS so positive criticism will help me learn!
Thanks!
You can use the setInterval function to execute your code every X ms
