Javascript: Can I Use JS to Copy an HTML Element From One Page to Another?

New to JS. Couldn't find any good solutions for this after researching, and seems like it shouldn't be too complicated.
Say I have a page called page1.html with this code:
<div class="page1">
<div class="wrapper">
<p>Some text.</p>
</div>
</div>
Now, I have a second page, page2.html, with this code:
<div class="page2">
</div>
I want to make a copy of the div with class wrapper from page1.html, and insert it into page2.html, within the div with class page2.
Both pages share the same script.js file.
I tried something like this:
page1content = document.querySelector('.wrapper');
page2content = document.querySelector('.page2');
page2content.append(page1content);
However, I'm getting errors on page1.html because the js can't find the div with class page2, and I'm getting errors on page2.html because the js can't find the div with class wrapper.
I found a similar question here, and a couple comments suggest using localStorage.
I am unfamiliar with localStorage so I tried to do some research, and tried something like this:
On page1.html I inserted this script at the bottom:
<script>
var pageContent = document.querySelector(".page1").innerHTML;
sessionStorage.setItem("page1content", pageContent);
</script>
On page2.html I inserted this script at the bottom:
<script>
document.querySelector(".page2").innerHTML=sessionStorage.getItem("page1content");
</script>
It didn't work for me, but perhaps I used it incorrectly.
I also tried to use cloneNode(), but again, wasn't sure how to transplant the clone of the element onto a new page, only onto the same page I'm cloning from.
Is there another way to accomplish what I'm trying to do?
Obviously this is a very basic example; my actual code will be pumping in much more content from page 1 to page 2, but I just want to get the concept working at least.

The code I had in my example in the description was almost correct, I just had to change sessionStorage to localStorage and it worked.

Add class on hover on Angular JS

I'm trying to add a class when hovering the li element in the code below with Angular
<li ng-mouseenter="cola-selected=true" class="pull-left" ng-class="{'selected' : cola-selected}">
<a href="interna.html">
<img src="assets/images/cola.png">
</a>
</li>
This is all the functionality the page will have, so I though maybe it is not necessarily to add a new js file for the js.
When the mouse enter to the li it should have the new class selected. The code above it is not working, and I cannot figure out why.
Here is an example of my code on a fiddle: https://jsfiddle.net/mjrmeffc/

Why do you need an extra file if you can write the logic in your angular application?
I assume you make use of ng-app and have a so called javascript file where your logic is, and you should include it in here.
Here is an example of the proper way of adding/removing a class.
<div ng-app>
<div
class="italic"
ng-class="{red: hover}"
ng-mouseenter="hover = true"
ng-mouseleave="hover = false">
Test 1 2 3.
</div>
</div>
NB I found this in another stackoverflow question, please make proper use of google search first, I don't have enough reputation to flag your question, or to make a comment.
* EDIT *
It seems like you're not yet familiar with AngularJS. You need to include your 'app.js' or 'script.js' whatever you want to call it. In there you define your application using
var app = angular.module('yourappname', [/* add your dependencies here*/]);
//Other logic like controllers or services
And your HTML should be
<div ng-app="yourappname">
<div ng-controller="yourController">
PLEASE ORIENTATE YOURSELF FIRST BEFORE YOU START ASKING QUESTIONS

Try using ng-mouseover attr
<li ng-mouseover="hoverIn()" class="pull-left" ng-class="{{applyClass}}">
write a function hoverIn() in your script and assign value when hover over
$scope.hoverIn = function() {
this.applyClass = "red";
}

Trying to build a content locker using jQuery

I am very new to jQuery and not entirely sure what I'm doing. Will try my best to explain the problem I'm facing.
I'm trying to lock some content on a landing page until a user shares the link using FB, Twitter, LinkedIN or G+. The first version of the script I wrote (which worked fine) ran like this:
<head>
<script type="text/javascript">
...
$(document).ready(function()
{
$('.class').click(clearroadblock());
buildroadblock();
}
</script>
<style>
.class
{
[css stuff]
}
</style>
</head>
<body>
<div id="something">
<ul>
<li> Link1 </li>
<li> Link2 </li>
</ul>
</div>
</body>
The problem I'm now facing is changing out this code to replace the list elements with social share buttons. As they are no longer under .class, but classes like fb-share-button and twitter-share-button. Please help me understand what I need to modify to accommodate this? PS: This is not a Wordpress site.
function clearroadblock()
{
$('#roadblockdiv').css('display', 'none');
$('#roadblockBkg').css('display','none');
}
This is the way I'm clearing the overlay once a click is detected, BTW.
Can I wrap the social buttons in divs, assign them IDs and use those IDs to trigger the click like below?
<div id="Button">
Tweet
</div>
$('#Button').click(clearroadblock());

You can have multiple classes on an element by separating them with a space. Try the following:
class="class fb-share-button"
Your jquery will still work off the "class" class. I would recommend you change this name to something more meaningful though. Your css can target the "class" for general styles, but you can also target fb and twitter separately.
Update
I decided to create a quick JSFiddle for this.
Some of the styles etc won't be the same as what you're doing, but the problem is resolved. I've created a div with id main that contains the content that you want to hide. There's an absolutely positioned div over the top of this, this is the roadblock. The javascript is showing the roadblock (assuming that's what you wanted to do with buildroadblock()).
On click of a link in the ul with id socialMedia we call clearroadblock. Notice the lack of parenthesis. This hides the roadblock.
This isn't a great way of preventing someone from seeing information, you might want to think about pulling the content down from the server when the action is performed, however, I think this answers your question.

Formatting dynamically formed HTML elements created after Script is run

So this is actually a very tricky concept to portray so here is my attempt.
I am utilizing an HTML form template in LANDesk Service Desk - tool is irrelevant but important to note that there is back-end code that I cannot touch that is generating HTML.
So basically, the tool is pulling data from a back-end database containing a list of objects. It then inputs this data into an HTML form template that I have created using variables as placeholders for the objects. The HTML is then built on the fly with however many objects are in the database. Thus, I have no way of accessing the head - (which means native JS, and inline CSS).
My template looks like this...
<div class="my-template">
<a class="my-template my-link">My Link</a>
</div>
<script>
var myLinks = document.getElementsByClassName('my-link');
for (var i = 0 ; i < myLinks.length ; i++) {
myLinks[i].style.display = "none";
}
</script>
When I view the source on the loaded page it looks something like this...
<body>
<!--misc. page stuff-->
<!--First Item-->
<div class="auto-create">
<div class="my-template">
<a class="my-template my-link">My-Link</a>
</div>
</div>
<!--Second Item-->
<div class="auto-create">
<div class="my-template">
<a class="my-template my-link">My-Link</a>
</div>
</div>
</body>
All of the elements are formatted the way I want them to be...besides the last element on each page. I have determined that this is because each time the tool is running the object through the template, it is running the script. The issue is, there is a stupid default button that they place at the bottom of each object that is broken. (This is why I have the script changing the style to display: none..should have mentioned this earlier). Basically I want to delay the execution of the script until not only the object has been run through the template...but the entire page has loaded...but I can't seem to get the last button to go away.
I know that this is a lot of poorly written words trying to form an explanation, but I really think this is impossible...but I am convinced there has to be a way. (Also, the company isn't providing us with any help in finding a workaround, so I had to basically MacGyver this one

template insertion in a editor

Describing a scenario:
I am going through the code mentioned below.B asically I am trying to figure out how to program so that
when a user clicks on "Use Template" button , it gets inserted into an editor.
Page 1:
There are lot of templates present
When a user clicks on the "Use Template" button on , it gets inserted into an editor that is present in
the next page (Page 2).
Please find the code snippet below for the first two templates I am going through:
<div id="templatesWrap">
<div class="template" data-templatelocation="templateone" data-templatename="Template ONE" data-templateid="" >
<div class="templateContainer">
<span>
<a href="https://app.abc.com/pqr/core/compose/message/create?token=c1564e8e3cd11bc4t546b587jan31&sMessageTemplateId=templateone&sHubId=&goalComplete=200" title="Use Template">
<img class="thumbnail" src="templatefiles/thumbnail_010.jpg" alt="templateone">
</a>
</span>
<div class="templateName">Template ONE</div>
<p>
Use Template
</p>
</div>
</div>
<div class="template" data-templatelocation="templatetwo" data-templatename="Template TWO" data-templateid="" >
<div class="templateContainer">
<span>
<a href="https://app.abc.com/pqr/core/compose/message/create?token=c1564e8e3cd11bc4t546b587jan31&sMessageTemplateId=templatetwo&sHubId=&goalComplete=200" title="Use Template">
<img class="thumbnail" src="templatefiles/thumbnail_011.jpg" alt="templatetwo">
</a>
</span>
<div class="templateName">Template TWO</div>
<p>
Use Template
</p>
</div>
</div>
And so on ....
How does the link "https://app.abc.com/pqr/core/compose/message/create?token=c1564e8e3cd11bc4t546b587jan31&sMessageTemplateId=templatetwo&sHubId=&goalComplete=200" is inserting the template into the editor which is located on the next page? I haven't understood the token part and lot's of ID's present in the link
which I think are thereason behind inserting the template.
Has anyone come across such link before? Please advise.
Thanks
MORE CLARIFICATIONS:
Thanks for your answer.It did help me somewhat. I have few more questions:
Basically, I am using TinyMCE 4.0.8 version as my editor. The templates, I am using are from here:
https://github.com/mailchimp/email-blueprints/blob/master/templates/2col-1-2-leftsidebar.html
Some questions based on "Tivie" answer.
1) As you can see in the code for "2col-1-2-leftsidebar.html " it's not defined inside <div> tags unlike you defined it in <div> tags. Do you think that I can still
use it using "2col-1-2-leftsidebar.html " name?
2)I believe,for explanation purpose, you have included
`"<div contenteditable="true" id="myEditor">replaced stuff</div>`
and
<button id="btn">Load TPL</button>
<script>
$("#btn").click(function() {
$("#myEditor").load("template.html");
});
</script>
in the same page. Am I right? ( I understand you were trying to make an educated guess here, hence
just asking :) )
In my case, I have a separate page, where I have written code for buttons just like you wrote in editor.html like the following:
<button id="btn">Load TPL</button>. My button is defined inside <div class="templateContainer">.
Also, my templates are defined in a separate folder. So, I will have to grab the content(HTML Template), from
that folder and then insert into TinyMCE 4.08 editor. (Looks like two step process). Could you elaborate
on how should I proceed here?
More Question As of Dec 27
I have modifier my code for the template as follows:
<div class="templateName">Template ONE</div>
<p>
Use Template
</p>
Please note, I have added an additional id attribute for the following purpose.
If I go by the answer mentioned in the Tivia's post, is the following correct?
<script>
$("#temp1").click(function() {
$("#sTextBody").load("FolderURL/template.html");
});
</script>
My editor is defined like the following on Page 2 (Editor Page).
<div class="field">
<textarea id="sTextBody" name="sTextBody" style="width:948px; max-width:948px; height: 70%"></textarea>
</div>
I am confused, like, the script tag I have defined is in Page 1 where I have defined all the template related code
and the Page 2(Editor) page is a different page. It's simply taking me to Editor page (Page 2) and hence not working.
Please advise where I am wrong.
Thanks
MORE QUESTIONS AS of Jan 2
The problem Iam facing is as follows. Basically, for first template , I have the following code.
Code Snippet #1 where "Use "Template" button is present:
<div class="templateName">Template ONE</div>
<p>
Use Template
</p>
And the function suggested in the answer is as follows:
Code Snippet #2 where Editor is present:
<script>
$("#temp1").click(function() {
$("#sTextBody").load("FolderURL/template.html");
});
</script>
Since, I believe I first need to reach to that page after user clicks on "Use Template" button, where the editor is located, I have defined Code Snippet #1 on Page 1 and have defined the Code Snippet #2 and <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script> as the very first two script tags in the Page 2 ( Editor Page). But still when I click on "User Template" button on Page 1, it's just letting me to next page and not loading the template into the editor.
Am I doing something wrong here? Please advise.
P.S. The problem I feel is somehow the click function on Page 2 is not getting activated with the temp1 id button mentioned on Page 1.
Thanks

Well, one can only guess without having access to the page itself (and it's source code). I can, however, make an educated guess on how it works.
The URL params follows a pattern. First you have a token that is equal in all templates. This probably means the token does not have any relevance to the template mechanism itself. Maybe it's an authentication token or something. Not relevant though.
Then you have the template identification (templateOne, templateTwo, etc...) followed by a HubId that is empty. Lastly you have a goalComplete=200 which might correspond to the HTTP success code 200 (OK).
Based on this, my guess would be that they are probably using AJAX on the background, to fetch those templates from the server. Then, via JScript, those templates are inserted into the editor box itself.
Using JQuery, something like this is trivial. here's an example:
template.html
<div>
<h1>TEST</h1>
<span>This is a template</span>
</div>
editor.html
<!DOCTYPE HTML>
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
</head>
<body>
<div contenteditable="true" id="myEditor">
replaced stuff
</div>
<button id="btn">Load TPL</button>
<script>
$("#btn").click(function() {
$("#myEditor").load("template.html");
});
</script>
</body>
</html>
Edit:
1) Well, since those templates are quite complex and include CSS, you probably want to keep them separated from you editor page (or the template's CSS will mess up your page's css).
However, since you're using TinyMCE, it comes with a template manager built in, so you probably want to use that. Check this link here http://www.tinymce.com/wiki.php/Configuration:templates for documentation.
2) I think 1 answers your question but, just in case, my method above works for any page in any directory, provided it lives on the same domain. Example:
<script>
$("#btn").click(function() {
$("#myEditor").load("someDirectory/template.html");
});
</script>
I recomend you check this page for the specifics on using TinyMCE http://www.tinymce.com/wiki.php/Configuration:templates
EDIT2:
Let me explain the above code:
$("#btn").click(function() { });
This basically tells the browser to run the code inside the brackets when you click the element with an id="btn"
$("#myEditor").load("someDirectory/template.html");
This is an AJAX request (check the documentation here). It grabs the contents of someDirectory/template.html and places them inside the element whose id="myEditor"
