Preload HTML from within Javascript file, into the DOM, but don't execute

Im creating a simple JS game, which will run in the browser and will pull the files directly from the pc. Because of this needed to make a workaround the "Cross-origin" error, which went smoothly, I put all the HTML within a JS and loaded the JS from the tag in the index.html. Everything was going smoothly so far.
You click "press any key to continue" -> but then next you click "New Game" and you get event listener error "can't set property of null". Which i don't understand how it happens, because the element is already in the "DOM" , the css could pick it up, but the event listener could not? So i tried moving all scripts on top, rearranging stuff, nothing worked. Pre-loading all HTML into the index.html, without executing it will definitely work, but how can i achieve this exactly? My Configuration atm is:
index.html (root folder)
/components/main_menu.js
/components/character_creation.js
function MainMenu()
{/*
<div id="mm_wrapper_grid">
<div id="mm_subgrid1">
</div>
<div id="mm_subgrid2">
<div id="mm_subgrid2_image"></div>
<div id="mm_new_game"><p id="mm_new_game_p" class="grow">New Game<p></div>
<div id="mm_load_game"><p id="mm_load_game_p" class="grow">Load Game</p></div>
<div id="mm_options"><p id="mm_options_p" class="grow">Options</p></div>
<div id="mm_credits"><p id="mm_credits_p" class="grow">Credits</p></div>
</div>
</div>
*/}
function CharacterCreation()
{/*
<div> Character Creation test
</div>
*/}
<div id ="game">
<div id="loading_screen">Press Any Key To Continue</div>
</div>
<script type="text/javascript">
document.getElementById("loading_screen").addEventListener("click", function() {callback("game", MainMenu)});
document.getElementById("mm_new_game_p").addEventListener("click", function() {callback("game", CharacterCreation)});
function callback(arg1, func)
{
var html = func.toString();
var htmlstart = html.indexOf('/*');
var htmlend = html.lastIndexOf('*/');
var html = html.substr(htmlstart+2, htmlend-htmlstart-2);
document.getElementById(arg1).innerHTML = html;
}
</script>

You have the problem because you are trying to add the second listener for getElementById("mm_new_game_p") when this element doesn't exist on the page. I suggest you to add the follwing line of code to make sure, that it's true:
<script type="text/javascript">
document.getElementById("loading_screen").addEventListener("click", function() {callback("game", MainMenu)});
console.log('#mm_new_game_p', document.getElementById("mm_new_game_p"));
document.getElementById("mm_new_game_p").addEventListener("click", function() {callback("game", CharacterCreation)});
...
You have to add this listener after this element will be created (after calling of MainMenu() function).
To tell the truth, I can see such storing of html templates in js functions for the first time. It's hard to support your code and I've modified it a little bit below. This is not the best way to implement it, but my goal is show you a solution based on your code. What you can see here:
all the templates for pages are in html (not in JS);
you can add listeners from html code using HTML attribute onclick - and in this case you can be sure, that element exists on the page.
If you want to add listeners from JS, than you have to create own functions for each pages which you have and after HTML template of a page will be added to #game container you will need to create event listeners for the buttons which are on the created page.
openPage("game", "loading_screen");
function openPage(parentDOMElementId, name) {
console.log('openPage:', name);
var pageHtml = document.getElementById("page_" + name).outerHTML;
document.getElementById(parentDOMElementId).innerHTML = pageHtml;
}
<div id="game"></div>
<div class="templates" style="visibility: hidden;">
<div id="page_loading_screen" onclick="openPage('game', 'main_menu')">
Press Any Key To Continue
</div>
<div id="page_main_menu">
<div id="mm_subgrid1">
</div>
<div id="mm_subgrid2">
<div id="mm_subgrid2_image"></div>
<div id="mm_new_game">
<p id="mm_new_game_p" class="grow" onclick="openPage('game', 'character_creation')">New Game
<p>
</div>
<div id="mm_load_game">
<p id="mm_load_game_p" class="grow">Load Game</p>
</div>
<div id="mm_options">
<p id="mm_options_p" class="grow">Options</p>
</div>
<div id="mm_credits">
<p id="mm_credits_p" class="grow">Credits</p>

Flippant in RoR project

I am newbie in front-end web development.
I am using flippant.js for flipping the dialogue.
<div id="overlay-box" class="overlayBox">
<a class="closeBtn" onClick="closePop()">X</a>
<button id="flipCard">Flip</button>
<div class="content" ></div>
</div>
<script type="text/javascript">
var front = document.getElementById("overlay-box")
var back_content = "
<div class = 'overlayBox' style='top: 50.5px; left: 338px; display: block;'>
<h2>Hello</h2>
<a class = 'closeBtn' onClick = 'closePop()'>Y</a>
<button id = 'closeCard'>Back</button>
<div class = 'content'></div>
</div>"
var back
document.getElementById("flipCard").addEventListener('click',function(e){
back = flippant.flip(front, back_content,'card')
document.getElementById("closeCard").addEventListener('click',function(e){
back = back.close();
})
})
But the flippant plug-in asks for back_content rather than full HTML file.
I want to override that but facing a problem.
I tried to change the flippant.js file where it was taking content and converting that into HTML whereas the front document was not converted.
I am able to use it but then I will have to write my all HTML code in back_content variable which is ugly design.
I also tried to give HTML document directly by $(HTML_file).html but still no success.
The other problem is when I am giving all the HTML in the variable then it is not calling the js classes and all styling code also
Please suggest how to use flippant plug-in.
Thanks in advance
For flippant.js code refer to its github page https://github.com/mintchaos/flippant.js/blob/master/flippant.js

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"

Dynamic Content Swap via AJAX

Only this much now: I'm creating a vcard design for myself. My motivation is to make it look as good as possible. I want to apply to a webdesign company with this vcard to get a professional education for webdesign.
I still have a lot to change till it completely fulfills in my requirements, but this is my current version of the design I just uploaded to get you an overview over the design.
So as you can see it's focused on retro, vintage, ribbons and scetch elements.
Right know I want to get rid of these jerking content refreshs. So I thought a dynamic content swap via ajax and jQuery would be the best way to do it.
I never did much with js or actually ajax.
I want to ask you guys about a solution you think benefits in my design. I was thinking about something smoothly.
The content which needs to be changed is placed in
<nav>
(...)
<ul class="ribbon s"><!--Following links got the class="ribbon b/p/l/k"-->
<li class="ribbon-content">Link</li>
<!--
?content=blog
?content=portfolio
?content=lebenslauf
?content=kontakt
-->
</ul>
(...)
</nav>
<section id="content">
<div class="con clearfix">
(...)
</div><!--An empty div for possibly swapping without touching the vintage paper thing -->
</section>
http://robert-richter.com/boilerplate/

for example use jquery.
first add jquery to your html. within the domready-event you can register click events on your ribbon-menue. on each click you load the div-content from the given link-url in the html-part.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
$.ready(function(){
$(".ribbon-content a").on("click", function(event){
event.preventDefault();
$(".con").load($(event.target).attr("href"), function(){
// add code after loading - for example change classes of menue
})
});
})
</script>
additionly you can the the browser-history to enable the prev- and next-buttons of the browser.
