JavaScript : Piece of code that breaks my modals

I have a piece of code that will create a contextual menu on right-click on one input in my page. The code is supposed to add "{Keyword: }" to the input. The problem is when I add the JS below all the modals that I use stop working (not displaying). The modals are activated by a button click.
Contexctual menu HTML:
<div id='cntnr'>
<ul id='items'>
<li>{Keyword:fallback}</li>
<li>{KeyWord:fallback}</li>
</ul>
</div>
Contexctual menu JS:
$("#headline11").on("contextmenu",function(e){
e.preventDefault();
$("#cntnr").css({"left": e.pageX-3, "top": e.pageY-3});
$("#cntnr").fadeIn(200, startFocusOut);
});
function startFocusOut(){
$(document).on("click",function(){
$("#cntnr").hide();
$(document).off("click");
});
}
$("#items > li").click(function(){
$("#headline11").val($(this).text().replace("fallback", " "));
var input1 = document.getElementById("headline11");
setInputSelection(input1, 9, 10);
});
Button:
<button onclick="load();setTimeout(myFunction, 10)" class="myBtn1" data-toggle="modal" data-target="#build">1 - Create campaign</button>
The modal:
<div class="container">
<!-- Modal Preview-->
<div class="modal fade" id="build" role="dialog">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"></button>
<h4 class="modal-title">Your Campaign Preview1</h4>
</div>
<div class="modal-body">
<div id="hoursSaved"></div>
Some text here.
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
When I use {Keyword: Whatever here} in my input and submit, the modals stop working, but when I remove the JS above everything works, except the contextual menu of course.
It took me hours to debug my code and find what part of it is causing the problem, but I'm unable to understand why. Your help will be much appreciated.
Thank you,
EDIT: Here is a JsFiddle as requested in the comments. You'll have to run the code between each test to see the difference.

You'll have to use the contextual menu to add the {Keyword:} you can enter whatever you want after ":", it won't work if you past it.

I found the answer. I had to use:
function startFocusOut(){
$("#cntnr").on("click",function(){
$("#cntnr").hide();
$("#cntnr").off("click");
});
}
Instead of:
function startFocusOut(){
$(document).on("click",function(){
$("#cntnr").hide();
$(document).off("click");
});
}

Getting the id of the anchor tag which was clicked

This is a list representation of data which is coming from a php database.The list is fetched using a foreach php loop and the data inside the achor tag is populated accordingly.
<?php foreach($array as $iterate):?>
<div class="col-sm-3">
<div class="panel panel-default">
**<a onClick='theFunction();' id="hello" href="#myModal" style="text-decoration:none;">**
<div class="panel-heading">
<img src ="audi_sillhouete.jpg" style="height:100%; width:100%;">
<p id="10" style="position:absolute; top:10%; padding-left:5%; padding-right:15%;"><?php echo $iterate->test_name ?></p>
</div>
</a>
</div>
</div>
<?php endforeach;?>
As you can see here, inside the anchor tag i have href-ed it to a modal box which will show a message whenever the user clicks on any of the link. There is a button in the modal window which will take the user to a different page.
The issue is that i want to pass certain value along with the url, but cannot do so as the link to the next page is defined in the modal window specification part.
So i came up with this solution. I thought of using the id attribute of the anchor tag, I tried to get the id attribute of the anchor which was clicked using javascript.
<script type="text/javascript">
function theFunction()
{
var id = $('a', this).attr('id');
alert(id);
}</script>
From this i wanted to initialize a php variable and then use that php variable to pass as value in the href of the modal window button. But the value i am getting in the alert box is 'undefined' for some reason. I have tried all possible combinations of this.
$('a',this).attr('id');
$this.id;
Everything return 'undefined'.
Reference-This is the code for the modal window part.
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Instructions</h4>
</div>
<div class="modal-body">
Your test is about to commence. A timer will be initiated after the moment you start the test. You may choose to answer a question, or leave it empty. You can also attempt the questions in any order that you find suitable.<br><br>Upon completion of the test, click on "Submit" to see your performance statistics.<br><br><br>Good luck!
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Continue</button>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div><!-- /.modal -->

Please try this
$(document).on('click', 'a', function () {
alert(this.id);
});
DEMO

You can use other attribute in anchor like :
<a href='' id='hello' para-id='somevalue'></a>
alert($("#hello").attr("para-id"));

The below jQuery function runs through all the a tags on page load and adds id to the end of the link.
$(function(){
$('a').each(function(){
var id = $(this).attr('id');
var url = $(this).attr('href') + '?id=' + id;
$(this).attr('href',url);
});
});

Unloading data from a modal

I am using bootstrap 3.3.2. How could I remove the data from modal? I want the modal to appear as fresh as it was loaded the first time.
For example a modal like :
<div class="modal fade" id="pass" tabindex="-1" role="dialog" aria-labelledby="mypass" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<h4 class="modal-title text-center" id="mypass">Characteristics</h4>
<div class="modal-body">
<form class='form-inline'>
<div class='form-group'>
<label for='playernumber_pass'>Player number</label>
<input type='text' class='form-control' id='playernumber_pass' name='playernumber_pass'/>
</div>
<label class='checbox-inline'>
<input type='checkbox' id='completed' name='completed'>Completed
</label>
</form>
</div>
</div>
</div>
</div>
when loaded again has the field filled with the previous data. How could I make sure, that the fields and other items inside the modal are loaded fresh?
Here is the fiddle that showing the same data is loaded again, when modal reloads : fiddle
I tried the following, but it didn't work :
$('#pass').on('hidden.bs.modal', function () {
$('#pass').removeData();
})

You could cache .html() of the modal and restore it on a X.bs.modal event
var modalFreshContents = $('#pass').html();
// content of the modal will be restored when the modal is fully hidden
$('#pass').on('hidden.bs.modal', function (e) {
$(this).html(modalFreshContents);
});
Demo

you can use model on show event. This event fires immediately when the show instance method is called. If caused by a click, the clicked element is available as the relatedTarget property of the event. check model events
$('#pass').on('show.bs.modal', function () {
$('form.form-inline')[0].reset();
});

Bootstrap Modal Not Displaying, outputs JS

I have a bootstrap modal setup with the following code:
<div class="modal hide fade" id="myModal">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>Testimonials</h3>
</div>
<div class="modal-body">
<p>Test Text Here</p>
</div>
<div class="modal-footer">
<a class="btn" data-dismiss="modal">Close</a>
</div>
</div>
<button class="btns btn-3 btn-3g btnsx" data-toggle="modal" href="#myModal">More</button>
However, I am getting only a black background when clicking the button.
I am also seeing some of my js appearing at the bottom of my page (only when the modal code is inserted):
.on('submit', function() { var form = $(this); var post_data = form.serialize(); //Serialized the form data for process.php $('#loader').html('loadng Please Wait...'); $.ajax({ type: 'POST', url: 'http://shazconstruction.com/test/process.php', // Your form script data: post_data, success: function(msg) { $('#loader').html(''); // We know this is the form that needs fading in/out $('form#contactUs').fadeOut(500, function(){ $('form#contactUs').html(msg).fadeIn(); }); } }); return false; }); });
Here is the site where everything exists:
http://bit.ly/1dbf4Rz
For reference, this is the section with the modal setup:
http://i.imgur.com/1SlNR1s.png

Check out the source of your page. However it's being generated has a pretty clear error: http://screencast.com/t/GZv0KwPktoO
Look at line 762. There is no opening script tag, so that would explain why you're seeing your JS appearing at the bottom of the page.
As for the rest of it, BaBL86 is right, you will want to fix the issue with your mousewheel script as it's throwing errors that cause the page to stop rendering JS.
Once those two issues are fixed, let us know if there are still problems.
Edit: You also have incorrect HTML for your modal window (based off the bootstrap 3 documentation). Try using this instead, and moving your modal window to right after the body tag:
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>Test Header</h3>
</div>
<div class="modal-body">
<p>Test Text Here</p>
</div>
<div class="modal-footer">
<a class="btn" data-dismiss="modal">Close</a>
</div>
</div>
</div>
</div>

You have an error in your mousewheel function. Check this answer, it's about this problem:
function handler(event) {
< ---- >
return $.event.handle.apply(this, args); // error here
}
Edit your function to:
return $.event.dispatch.apply(this, args);

You have given !important to .hide. Remove the imporant
From this
display: none!important;
To
display: none;
I can also see that you are not giving any background-color. Use the same code from bootstrap

Passing Data to Bootstrap Modals

I am trying to create a simple modal using twitter bootstrap. The function of that modal is to take the name of the link clicked on, and use that name as a header. Each of the names are in a Django Database. I followed this link for reference: Passing data to a bootstrap modal
#Button to toggle modal
<a data-toggle="modal" data-id="{{ name }}" title="Add this item" class="open- AddBookDialog " href="#addBookDialog">{{ name }}</a><br />
#Modal
<div class="modal hide fade" id="addBookDialog">
<div class="modal-header">
<button class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-body">
<input type="text" name="nameId" id="nameId" />
<p>some content</p>
</div>
</div>
#JavaScript
<script type="text/javascript">
$(document).on("click", ".open-AddBookDialog", function () {
var myNameId = $(this).data('id');
$("modal-body #nameId").val( myNameId );
});
</script>
What the above does is displays a text box with the characters name in the box. What I would like is to have the name as the header, not in a text box. When I remove the textbox, and place a header tag with the same id and name, nothing will show. Is there a way to complete this task.

the header is the first h3 in the modal.
So you need to add a h3 element under ".modal-header" with an id and set the .html() of that element. :)
Look here for reference: http://twitter.github.io/bootstrap/javascript.html#modals
Here's the code:
#Modal
<div class="modal hide fade" id="addBookDialog">
<div class="modal-header">
<button class="close" data-dismiss="modal">×</button>
<h3 class="hdrtitle">This is the header</h3>
</div>
<div class="modal-body">
<input type="text" name="nameId" id="nameId" />
<p>some content</p>
</div>
</div>
Using a code like:
$('.modal .hdrtitle').html('This is the header');
and then showing it with:
$('.modal').modal('toggle');
works.

The one-off way
If this is the only time you'll ever need to do a UI-binding behavior in your site/app, do something like this:
$('.header-link').click(function(e) {
$('.modal-header h4').html($(e.target).html())
})
CodePen Demo
This will just take the text (actually the HTML) in the link itself and put that in the header.
Using a library
If you plan to do these sorts of cool tricks in more parts of your app, consider using a UI-binding library like Angular JS or Knockout. This way you can data-bind parts of your UI with events.

I found the answer. Thanks to #PaoloCasciello for a layout.
Instead of an .on function in javascript, it really needed to be .html. So here is what the final code will look like.
<!-- Modal -->
<div class="modal hide fade" id="addBookDialog">
<div class="modal-header">
<button class="close" data-dismiss="modal">×</button>
<h3 id="nameId" />
</div>
<div class="modal-body">
<p>some content</p>
</div>
</div>
<script type="text/javascript">
$(document).on("click", ".open-AddBookDialog", function () {
var myNameId = $(this).data('id');
var myNameDescription = $(this).data('description');
$(".modal-header #nameId").html( myNameId );
