replace a div hidden intially by a click on a link from 3 other 3 linkes(3 other divs)

Hi I want to replace a div that is already displayed with another Hidden div choosed when i click on one of them(3 other divs(hidden) initially). the 4 links related to the 4 divs and in same way i can do that in each link clicked. below is the code:
<script type="text/javascript">
#4 Id of divs
var models = document.getElementById('models')
var geometry = document.getElementById('geometry')
var assembly = document.getElementById('assembly')
var loads = document.getElementById('loads')
#4 ID OF links (related to each div)
var models1 = document.getElementById('models1')
var geometryy = document.getElementById('geometryy')
var assemblyy = document.getElementById('assemblyy')
var loads1 = document.getElementById('loads1')
geometryy.addEventListener("click", function () {
models.style.display = "none"
loads.style.display = "none"
assembly.style.display = "none"
geometry.style.display = "block"
})
assemblyy.addEventListener("click", function () {
geometry.style.display = "none"
models.style.display = "none"
loads.style.display = "none"
assembly.style.display = "block"
})
loads1.addEventListener("click", function () {
geometry.style.display = "none"
models.style.display = "none"
assembly.style.display = "none"
loads.style.display = "block"
})
models1.addEventListener("click", function () {
models.style.display = "block"

Changing the css of code ouput on an HTML page with Skulpt

I have the following program (using skulpt) which generates python output in the browser on hitting "run". The output code is in the "pre" tags. I have tried various different things to apply the CSS to the executed output, but it isn't working.
This is my css
<style>
.running {
border: 20px outset black ;
background-color: black;
text-align: center;
p: color:white;
pre
{
white-space: pre-wrap !important;
}
}
</style>
This is the HTML part of the code.
<h3>Heading here</h3>
<form>
<textarea id="yourcode" cols="40" rows="10">
print("Hello World")
</textarea><br />
<button type="button" onclick="runit()">Run</button>
<button type="button" onclick="clearit()">Clear</button>
<button type="button" onclick="clearit()">--X--</button>
<button type="button" onclick="clearit()">--Y--</button>
<button type="button" onclick="clearit()">--Z--</button>
</form>
<br>
<br>
<br>
<div class="running">
<pre id="output" ></pre>
<!-- If you want turtle graphics include a canvas -->
<div id="mycanvas">
</div>
I assume it is this that is responsible for generating the output code:
<pre id="output" ></pre>
This is the javascript functionality (for reference) that produces the output code
<body>
<center>
<script type="text/javascript">
// output functions are configurable. This one just appends some text
// to a pre element.
function outf(text) {
var mypre = document.getElementById("output");
mypre.innerHTML = mypre.innerHTML + text;
}
function builtinRead(x) {
if (Sk.builtinFiles === undefined || Sk.builtinFiles["files"][x] === undefined)
throw "File not found: '" + x + "'";
return Sk.builtinFiles["files"][x];
}
// Here's everything you need to run a python program in skulpt
// grab the code from your textarea
// get a reference to your pre element for output
// configure the output function
// call Sk.importMainWithBody()
function runit() {
var prog = document.getElementById("yourcode").value;
var mypre = document.getElementById("output");
mypre.innerHTML = '';
Sk.pre = "output";
Sk.configure({output:outf, read:builtinRead});
(Sk.TurtleGraphics || (Sk.TurtleGraphics = {})).target = 'mycanvas';
var myPromise = Sk.misceval.asyncToPromise(function() {
return Sk.importMainWithBody("<stdin>", false, prog, true);
});
myPromise.then(function(mod) {
console.log('success');
},
function(err) {
console.log(err.toString());
});
}
function clearit(){
document.getElementById('yourcode').value = 'Your awesome code here';
document.getElementById('output').innerHTML = '';
}
</script>
Question: How do I format the code such that the background is black (this works) but the output code on pressing "run" is WHITE.
I don't know if it is due to missing out an ID - I notice the pre tags in the HTML have an id or incorrect use of the tags in the css. An explanation along with a solution (code) would be appreciated.
Other things I have tried in the CSS: (doesn't work either)
<style>
.running {
border: 20px outset black ;
background-color: black;
text-align: center;
p: color:white;
pre {
color:white;
display: block;
font-family: monospace;
white-space: pre;
margin: 1em 0;
}
}
</style>

It seems p: color: white; is invalid css, since p is an element not a style property. Instead, this line should be just color: white;.
Example snippet below:
.running {
border: 20px outset black;
background-color: black;
text-align: center;
color:white;
pre {
white-space: pre-wrap !important;
}
}
<h3>Heading here</h3>
<form>
<textarea id="yourcode" cols="40" rows="10">
print("Hello World")
</textarea><br />
<button type="button" onclick="runit()">Run</button>
<button type="button" onclick="clearit()">Clear</button>
<button type="button" onclick="clearit()">--X--</button>
<button type="button" onclick="clearit()">--Y--</button>
<button type="button" onclick="clearit()">--Z--</button>
</form>
<br>
<br>
<br>
<div class="running">
<pre id="output">Test output should be white!</pre>
<!-- If you want turtle graphics include a canvas -->
<div id="mycanvas">
</div>

jQuery/Javascript : How to prepend elements without going back to the top of last prepended element?

Whenever I click prepend, after all elements are prepended, the view of the chat area switches to the top of the chat area or the last prepended element. This is different from append, whereby after all elements are appended, the view of the chat area does not switch to the end of the chat area or last appended element but still stays at its previous position.
How do I make the prepend function act in the same way as append in the sense that the view of the chat area does not change similar to FB's load previous message function?
Here is a sample code that illustrates what I mean.

</div>

</div>
</div>
</div>
</body>
</html>

In HTML there should be return in your onlick:
<a onclick="return loadMessage();" class="load btn btn-default">Load More Msg</a>
In JS you need to add return false to your function loadMessage.
var loadMessage = function(){
var firstMessage = $messagesWrapper.find('> p:nth-child(2)');
$.ajax({
....
if(messages.length<10){
$('.load').hide();//hide the load button if remaining messages to load is <10
}
success: function(messages){
$.each(messages, function() {
prependMessage(this);
});
},
....
});
return false;
};

Try this:
<div id="response" class="msg form-group">
<a onclick="loadMessage(); return false;" class="load btn btn-default">Load More Msg</a>
</div>
If this doesn't work, try another way:
var loadMessage = function(){
e.preventDefault(); // preventing any scroll action
var firstMessage = $messagesWrapper.find('> p:nth-child(2)');
(...)
And
var prependMessage = function(data){
e.preventDefault(); // preventing any scroll action
var message = document.createElement('p');
(...)
If this doesn't work please provide the whole code so we can reproduce.

AngularJS: Function call on ngSwipeLeft

Title pretty much explains it all. Inputting ngSwipeLeft="someFunction()" does not seem to work as I hoped it would. Maybe I am doing it wrong, but what are your ideas? Here is the documentation for ngSwipeLeft.
Example
Thanks,
Ben

I think what you need to do is create a controller for that javascript, and then work off of its scope.
<div ng-show="!showActions" data-ng-swipe-left="someFunction()">
Some list content, like an email in the inbox
</div>
<div ng-show="showActions" data-ng-swipe-right="someFunction()">">
<button ng-click="reply()">Reply</button>
<button ng-click="delete()">Delete</button>
</div>
And the JS
$scope.showActions = false;
$scope.someFunction = function () {
$scope.showActions = !$scope.showActions;
};
That is how I do it in my applications. I hope it helps.
Here is the Plunk.
The plunk works but it is a little off. It sometimes highlights instead of switching over. It works best when swiping to the right side.

<div ng-controller="MyCtrl">
<div>
<div>
<pre> Left swipes: {{model.left}}</pre>
</div>
<div>
<pre>Right swipes: {{model.right}}</pre>
</div>
<div>
<pre>Touch clicks: {{model.click}} </pre>
</div>
</div>
<div class="swipy"
ng-swipe-left="swipeLeft()"
ng-swipe-right="swipeRight()"
ng-click="touchClick()">
Swipe me !
</div>
</div>
<style type="text/css">
div {
font-size: 0.9em;
}
div.swipy {
text-align: center;
padding: 15px;
margin: 5px;
border-radius: 2px;
border: 3px groove gray;
background-color: light-gray;
}
</style>
<script type="text/javascript">
app.controller('MyCtrl', function ($scope) {
$scope.model = {
left: 0,
right: 0,
click: 0
};
$scope.swipeLeft = function () {
$scope.model.left += 1;
};
$scope.swipeRight = function () {
$scope.model.right += 1;
};
$scope.touchClick = function () {
$scope.model.click += 1;
};
});

Creating boxes in javascript

I am trying to create multiple boxes along the top of the page using javascript. I have one box but cannot figure out how to get multiple along the top of the page. This is what I have so far:
<html>
<head>
<title>Boxes on Boxes on Boxes</title>
<link rel="stylesheet" type="text/css" href="boxes.css">
<script language="JavaScript">
el=document.getElementById("box1");
width=window.innerWidth-50;
height=window.innerHeight-50;
el.style.left=width*Math.random();
el.style.top=height*Math.random();
el=document.getElementById("box2");
width=window.innerWidth-50;
height=window.innerHeight-50;
el.style.right=width*Math.random();
el.style.top=height*Math.random();
el=document.getElementById("box3");
width=window.innerWidth-50;
height=window.innerHeight-50;
el.style.middle=width*Math.random();
el.style.top=height*Math.random();
</script>
</head>
<body>
<div id="box1">
First box
</div>
<div id="box2">
Second box
</div>
<div id="box3">
Third box
</div>
</body>
</html>
Here is the CSS that I have:
#box1{
background-color:orange;
padding:5px;
width:50px;
height:50px;
position:absolute;
left=100px;
top=100px;
}
#box2{
background-color:blue;
padding:5px;
width:50px;
height:50px;
position:absolute;
left=100px;
top=100px;
}
#box3{
background-color:green;
padding:5px;
width:50px;
height:50px;
position:absolute;
left=100px;
top=100px;
}

You need to either move the <script> element to the end or wrap your code in a DOM ready or onload handler, because otherwise getElementById() won't find any elements because they won't have been parsed yet.
Then you need to include a unit (e.g., "px") in the left and top style properties.
Also there's no need to recalculate the width and height for each box since you're doing the same calculation for each. (And you should declare your variables with var, but although good practice that isn't essential to make it work.)
Here's a working version:
var el=document.getElementById("box1");
var width=window.innerWidth-50;
var height=window.innerHeight-50;
el.style.left=width*Math.random() + "px";
el.style.top=height*Math.random() + "px";
el=document.getElementById("box2");
el.style.right=width*Math.random() + "px";
el.style.top=height*Math.random() + "px";
el=document.getElementById("box3");
el.style.middle=width*Math.random() + "px";
el.style.top=height*Math.random() + "px";
Demo: http://jsfiddle.net/m3Gg3/
Also the left and top properties in your CSS should use : not =.

It is difficult to understand what you want, maybe this?.
<script>
window.onload = function() {
var titles = ["First box", "Second box", "Third box"]
var width=window.innerWidth-50
var height=window.innerHeight-50-120
for (var i = 0; i < titles.length; i++) {
var el = document.createElement('div')
console.log(el)
el.innerHTML = titles[i]
el.style.position = "absolute"
el.style.border = "1px solid rgb(0,0,0)"
el.style.left= (width / titles.length) * i
el.style.top=0
el.style.width = width / titles.length
el.style.height = "120px"
document.body.appendChild(el);
}
for (var i = 0; i < titles.length; i++) {
var el = document.createElement('div')
console.log(el)
el.innerHTML = titles[i]
el.style.position = "absolute"
el.style.border = "1px solid rgb(0,0,0)"
el.style.left=0
el.style.top=(height / titles.length) * i + 120
el.style.width = "120px"
el.style.height = height / titles.length
document.body.appendChild(el);
}
}
</script>

Try this using jQuery :
Here the boxes should be created dynamically and without naming the id's hardcoded it also should be done in a better way with your code. It's easier now as you are creating 4 boxes, what about 100 or more. So it's wise to always take the better way to maintain scalability of our work.

<div id="mainDiv">
