Disable background scrolling when a modal is enabled

I am using a template with the following code to handle scrolling:
Here is the template.
This is the javascript code for scrolling, I can post the html and css if needed but it is large.

var canScroll = true,
scrollController = null;
$(this).on('mousewheel DOMMouseScroll', function(e){
if (!($('.outer-nav').hasClass('is-vis'))) {
e.preventDefault();
var delta = (e.originalEvent.wheelDelta) ? -e.originalEvent.wheelDelta : e.originalEvent.detail * 20;
if (delta > 50 && canScroll) {
canScroll = false;
clearTimeout(scrollController);
scrollController = setTimeout(function(){
canScroll = true;
}, 800);
updateHelper(1);
}
else if (delta < -50 && canScroll) {
canScroll = false;
clearTimeout(scrollController);
scrollController = setTimeout(function(){
canScroll = true;
}, 800);
updateHelper(-1);
}

How can I disable this code so the background doesn't scroll when an elements display is set to "block" meaning a modal is present?
Sorry for being vague if you need more specifics let me know!
EDIT 1:
I have tried disabled the div using:
$(".l-viewport").attr('disabled','disabled');
I have set the z-index of the model above all else

you can create a class HideScroll in your css:
.HideScroll {
overflow-y: hidden !important;
overflow-x: hidden !important;
}
The in the code that displays your modal, add this css to your main div:
$('.yourMainDivClass').addClass('HideScroll')
upon modal close, remove the class:
$('.yourMainDivClass').removeClass('HideScroll')
you can also use jquery toggleClass function.
OR
you can wrap your main div inside <fieldset> and set it's disabled attribute to true:
<fieldset id="fs-1">
<div id="yourMainDiv"></div>
</fieldset>
upon showing modal:
$('#fs-1').attr('disabled', true);
upon closing modal:
$('#fs-1').removeAttr('disabled');

Create a javascript object

I would say I am fairly decent with javascript and jQuery, well, enough to get the job done and done pretty well.
I do however lack a deep understanding of js.
I have created some functions for highlighting table elements.
ctrl+click toggles selections
shift+click+drag highlights selection
My question does not pertain to whether or not my implementation is the best way or not but ...
How do I abstract this functionality so I can add this functionality to any table. Like if I add more highlighting features and such and put this in its own .js file. How would I attach it to any html table?
Sorry if this has already been answered, but I could not think of what to search for.
Thank you.
****Newest Code****
This code is in its own .js file and is attached to my table.
All the current functionality is there. The only thing I am weary of is the .off() functions. In my case, I am reloading new tables.... as I type this, I realize I should just empty the tr's from the table instead of recreating a new table all the time, then I could get rid of the .off() calls.

you can wrap all this in a function since you have some local variables related to individual selection
$.fn.addEvents = function(obj) {
var properties = $.extend(true, {
shifting: false,
ctrling: false,
mousing: false,
mouseenter: 0,
mouseleave: 0,
trajectory: null
}, obj || {});
return $(this)
.off('click')
.off('contextmenu')
.on('click', function() {
.....
})
.on('mouseleave', function(e) {
//rename your local variables with `properties.` prefix
properties.mouseleave = e.clientY;
if (properties.shifting && properties.mousing) {
tmptrajectory = properties.mouseenter - properties.mouseleave < 0 ? 1 : -1;
}
if ($(this).hasClass('selected') && properties.shifting && properties.mousing && properties.trajectory != null && properties.trajectory != tmptrajectory) {
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}
....
});
}
usage
$('#datatablebody tr').addEvents({ shifting: false, ctrling: true }); //custom settings
$('#someother tr').addEvents(); //default settings

you could add that functionality to a class and add that class to the tables you want to affect...
Here I create the class .myTableBeh and all tables with that class will have the behaviour you programmed.
var shifting = false;
var ctrling = false;
var mousing = false;
var mouseenter = 0;
var mouseleave = 0;
var trajectory = null;
$('.myTableBeh tr')
.off('click')
.off('contextmenu')
.on('click', function()
{
if(!ctrling)
{
$('.myTableBeh tr, .myTableBeh tr td').removeClass('selected');
$(this).addClass('selected');
$(this).find('td').addClass('selected');
}
else if(ctrling && $(this).hasClass('selected'))
{
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}
else if(ctrling && !$(this).hasClass('selected'))
{
$(this).addClass('selected');
$(this).find('td').addClass('selected');
}
})
.on('contextmenu', function(ev)
{
ev.preventDefault();
$('.myTableBeh tr, .myTableBeh tr td').removeClass('selected');
$(this).addClass('selected');
$(this).find('td').addClass('selected');
showContextMenuTR($(this).closest('tr').attr('id'), ev.clientX, ev.clientY);
return false;
})
.off('mousedown')
.on('mousedown', function(e)
{
mousing = true;
multiselectrow($(this));
})
.off('mouseenter')
.on('mouseenter', function(e)
{
mouseenter = e.clientY;
multiselectrow($(this));
})
.off('mouseleave')
.on('mouseleave', function(e)
{
mouseleave = e.clientY;
if(shifting && mousing)
{
tmptrajectory = mouseenter - mouseleave < 0?1:-1;
}
if($(this).hasClass('selected') && shifting && mousing && trajectory != null && trajectory != tmptrajectory)
{
$(this).removeClass('selected');
$(this).find('td').removeClass('selected');
}
if(shifting && mousing && trajectory == null)
{
trajectory = tmptrajectory;
}
})
.off('mouseup')
.on('mouseup', function(e)
{
mousing = false;
trajectory = null;
multiselectrow($(this));

Thanks to the answer from #JAG I was able to create a nice add on to any HTML table that handles highlighting.
Check out the fiddle for the working version and please use it if you find it helpful or useful for your site.
You can even implement keys to move the tr position up or down in the table. I removed my implementation because it was specific to the project I am working on.
I made it so you have to mouse over the table in order to interact with it and mouse leave to un-focus it.
https://jsfiddle.net/kwj74kg0/2/
//Add the events simply by running this
$('#dtable tr').addEvents(0);
/**
* This add on can be applied and customized to any html tr set i.e. $('#tableid tr').addEvents()
* It will add highlighting capability to the table.
*
* Single click highlight tr
* Click -> Shift + click highlight/toggle range
* Shift+MouseDown+Drag highlight/toggle range
* Ctrl+Click toggle item

Why will my Javascript not run in IE

Below is my code. It is supposed to filter a table. It functions great in everything but IE. Can you help?
Perhaps there is a missing tag or something. I've been over it a number of times and could really do with someone's help please!
<script type="text/javascript">

Check your semicolons. IE is far more strict on that kind of stuff than FF.

Issue with my drag and drop plugin

I'm currently developing a Drag n' Drop plugin. I have just finished a feature so people could drop the draggable item on a target. Now it works perfect on the jsfiddle:
http://jsfiddle.net/XvZLn/18/
But once I implement that code into my plugin the following wont work:
var target = {
on: function() {
return $('.drag:first').each(function() {
$(this).addClass('i');
});
},
off: function() {
$('.drag:first').removeClass('i');
}
};
Which in my plugin it looks like this:
var targ = {
on: o.target.onTarget,
off: o.target.offTarget
};
Both of the codes have there purposes. The the on part is the function that is suppose to be launched when you enter all the way in the target. The off part is the function that gets launched when leaving the target.
onTarget and offTarget are all options in the defaults.
The reason we this var is because we needed a way to use function(){}.
The only way I thought I could do this is in an var.
Now Im trying to launch targ.on() inside the if that checks if the element is all the way inside the target. This is not working. I know the targ.on() is not working because I added an alert in the if and and I got the alert once the element got in the target.
This the the full code I use in my plugin:
var locker = o.target.lock;
var lock = false;
var targ = {
on: o.target.onTarget,
off: o.target.offTarget
};
$(oj).bind('drag', function (event) {
var $t = $(this);
var $con = $(o.target.init);
if (lock === false) {
$(this).css({
top: event.offsetY,
left: event.offsetX
});
}
}).bind('mouseup', function () {
var $t = $(this);
var $con = $(o.target.init);
var sen = 100;
var otop = $t.offset().top;
var oleft = $t.offset().left;
var conw = $con.width();
var conh = $con.height();
var cono = $con.offset().top;
var conl = $con.offset().left;
var oo = $t.height();
sen = sen * 2;
var other = oleft <= conw - (sen / 1.25) && oleft > conl && oleft < conw + conl - (sen / 4);
if (locker === false) {
if (otop < conw - (sen / 4) && otop > cono && otop < ((conh + cono) - oo) && other) {
targ.on();
lock = false;
} else {
targ.off();
lock = false;
}
} else {
if (otop < conw - (sen / 4) && otop > cono && otop < ((conh + cono) - oo) && other) {
targ.on();
$(this).css('cursor', 'default');
lock = true;
}
}
});

I had to leave out the top part of the plugin because it told me there is a 30000 character limit.
Example: http://jsfiddle.net/ZDUZL/84/
Im not sure what the problem is, and im not sure if this is too much information or not. Thanks for any help.

This works in your first jsFiddle because you're relying on the offset directly from the drag event object:
$('.drag').bind('drag', function(event) {
var $t = $(this);
var $con = $('#container');
if (lock === false) {
$(this).css({
top: event.offsetY, // coordinates directly from event object
left: event.offsetX
});
}
})...
In the full plugin code, you get an offset in your dragstart event callback and then try to reference it from your drag event callback. The problem is that this dragstart event is not being triggered (or not at the proper time or on the proper element, anyway). When the drag callback looks for the values, they're undefined and your script is halted on the error. See here for reference:
var $div = (o.containment === 'parent') ? $(oj).parent() : ((o.containment === 'parent parent') ? $(oj).parent().parent() : ((o.containment === 'document') ? $(document) : $(o.containment)));
var j, b, r;
$('.ghost_starter' + random).bind("dragstart", function(event) { // this event isn't being triggered (or at least not at the right time or on the right element)...
j = $div.offset();
b = j.top + $div.outerHeight() - $(this).outerHeight();
r = j.left + $div.outerWidth() - $(this).outerWidth();
}).bind('drag', function(event) {
$(this).css({
top: Math.min(b, Math.max(j.top, event.offsetY)), // ...so b, j, and r aren't defined here
left: Math.min(r, Math.max(j.left, event.offsetX))
});
});
Fix that dragstart trigger or get your offset otherwise and you'll be set.
