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");
});
}

How to change text inside modal using jquery?

I am using this modal:
<div id="myalertbox" class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-body">
<button type="button" class="close" data-dismiss="modal">×</button>
You have a new notification!
</div>
<div class="modal-footer">
<button type="button" class="btn btn-primary" data-dismiss="modal">OK</button>
</div>
</div>
</div>
</div>
Which pops up and says "You have a new notification!". I pop it up by using this script:
<script>
function showAlert() {
$("#myalertbox").modal({
"backdrop": "static",
"keyboard": true,
"show": true,
});
}
</script>
I dont know how to change the text inside though? I tried with .text and .html but it doesn't work.

Change text before calling the modal as
$("#myalertbox .modal-body").text('pass your text here');

Before initiating the modal, you can change its html like:
$("#myalertbox .modal-body").html('pass your html here');
// It will put your html inside the div having Class .modal-body which is enclosed with a div having ID #myalertbox
and after that initiate its modal as usual way.

As the content is not nested into any tags.
It's better to use this one below.
var btnHtml='< button type="button" class="close" data-dismiss="modal">
&times ;< /button>';
$('#myalertbox .modal-body').html(btnHtml +"your text here");

how can i create a modal by remote and initial textbox in the same function using jquery?

script.js
function change_val(){
$("#remoteModal2").modal({
remote:"modals/edit_text_value.html",
show:true
});
$("#my_textbox").val("this is a text")
}
index.html
<div class="modal fade" id="remoteModal2" tabindex="-1" role="dialog" aria-labelledby="remoteModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
</div>
</div>
</div>
<button onclick="change_val()" >show modal</button>
edit_text_value.html
<div class="modal-header">
header
</div>
<div class="modal-body">
<textarea id="my_textbox"></textarea>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">cancel</button>
</div>
The problem is that I must run it twice to make it work !
How to do all the operations in a function ?

shown.bs.modal OR show.bs.modal
When we use this code :
.on('shown.bs.modal')
.
$('#remoteModal2').on('shown.bs.modal', function (e) {
$("#my_textbox").val("this is a new text);
return e.preventDefault();
});
import modal (remote "edit_text_value.html")
Open modal
After the completion of loading and effects , change value..
show new value...
But this code :
.on('show.bs.modal')
Apply the changes ,Before reading the tags and remote the modal...
Therefore, it is not effective.
Because it can not find this ID (#my_textbox) Before remote modal page!

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);
});
});

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:

For reference, this is the section with the modal setup:

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
