Create a javascript object - javascript

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

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');

i cant hide jquery autocomplete with my functions

I am creating project which it searches musics dynamicly with JSON.
Here is my html:
<div id="custom-search-input">
<div class="input-group col-md-12">
<input type="text" class="form-control input-lg" placeholder="Search query..." id="searchquery" autocomplete="off" />
<span class="input-group-btn">
<button class="btn btn-info btn-lg" type="button" id="searchbuttonheader" onclick="search();">
<i class="glyphicon glyphicon-search"></i>
</button>
</span>
</div>
</div>
My search function called search(); ... Before I integrated jquery autocomplete I made when I click ENTER on keyboard in searchquery input it executes search(); function. To do this here is my JS code:
// ENTER KEY SEARCH //
$.fn.enterKey = function (fnc) {return this.each(function () {$(this).keypress(function (ev) {
var keycode = (ev.keyCode ? ev.keyCode : ev.which);
if (keycode == '13') {search();}})})
}
$("#searchquery").enterKey(function () {search();});
// ENTER KEY SEARCH //
OKAY ITS WORKING... BUT...
After integration the jquery autocomplete when I type something in searchquery input it gives some autocomplete data. Here is JS:
$('#searchquery').autoComplete({
minChars: 1,
delay: 500,
source: function(term, response){
$.getJSON('<?php echo $url_autocomplete; ?>', { query: term }, function(data){ response(data); });
},
onSelect: function(e, term, item){
search();
//alert('Item selected by '+(e.type == 'keydown' ? 'pressing enter' : 'mouse click')+'.');
}
});
When I click one of them the autocomplete hides and searches the text. But when I don't select any of them and hit enter it searches but the autocomplete is not hiding.
I WANT:
When I type something in searchquery input then I hit enter hide autocomplete suggestions and make search();.
You are not using jquery-ui-autocomplete but you use jQuery-autoComplete from Pixabay am I right? Ok, after see the code, there's no close method provided, so i add one to the original source code. You can copy and use below's jquery.auto-complete.js and call $("#searchquery").autoComplete('close'); to close the suggestion. See below example how to use it :
$("#searchquery").enterKey(function (e) {
$("#searchquery").autoComplete('close');
// .. DO YOUR SEARCH HERE ..
});
Use below's modified jquery.auto-complete.js.

JQuery scroll listbox imitation with keyboard navigation?

My javascript listbox implementation:
$(function() {
$('#listbox1').on('keydown', function(e) {
e.preventDefault();
e.stopImmediatePropagation();
var $e = $(this).find('.selected');
switch(e.which) {
case 38:
($e.prev().length) && ($e = $e.removeClass('selected').prev().addClass('selected'));
$(this).scrollTop( $e.position().top + $(this).scrollTop() );
break;
case 40:
($e.next().length) && ($e = $e.removeClass('selected').next().addClass('selected'));
$(this).scrollTop( $e.position().top + $(this).scrollTop() );
break;
}
});
});
Here is a fiddle: http://jsfiddle.net/7qy8p2x1/.
There are presented a real listbox and his imitation. I do not go so they scrolled the same using keyboard navigation arrows (up & down). A real listbox is not scrolling until it reaches the last element but imitation does so (following each element). ScrollUp is working properly.
Please, help me implement scrollDown behaviour correctly.
i use .jspPane for scrolling list, but u can it without jsp (if u ok with coffe) can show to you .coffee - it more readable. If u have question - ill help u
var keyboard_control, scroll_to_active;
keyboard_control = function() {
$('.control-edu').on('keydown', 'input', function(e) {
var $active, $first, $last, $this, i, temp;
$this = $(this);
$active = $('.jspPane span.active');
$first = $('.jspPane span.opinion').first();
$last = $('.jspPane span.opinion').last();
if ($this.closest('.control-edu').find('.options span').length > 1) {
if (e.keyCode === 38) {
if ($active.length > 0) {
if ($active.prev().length > 0) {
temp = $active.prev();
$active.removeClass('active');
temp.addClass('active');
} else {
$active.removeClass('active');
$last.addClass('active');
}
} else {
$last.addClass('active');
}
i = $('.jspPane span.active').closest('.control-edu').index();
scroll_to_active(i, 0);
} else if (e.keyCode === 40) {
if ($active.length > 0) {
if ($active.next().length > 0) {
temp = $active.next();
$active.removeClass('active');
temp.addClass('active');
} else {
$active.removeClass('active');
$first.addClass('active');
}
} else {
$first.addClass('active');
}
i = $('.jspPane span.active').closest('.control-edu').index();
scroll_to_active(i, 1);
} else if (e.keyCode === 13 && $active.length > 0) {
$active.click();
}
}
});
};
scroll_to_active = function(i, flag) {
var $active;
$active = $('.jspPane span.active');
if (flag === 1) {
if (($active.next().length > 0) && ($active.prev().length > 0)) {
api[i - 1].scrollToElement($active.next());
} else if ($active.prev().length === 0) {
api[i - 1].scrollToElement($active);
} else if ($active.next().length === 0) {
api[i - 1].scrollToBottom();
}
} else if (flag === 0) {
if ($active.next().length > 0) {

break;
case 40:

($e.position().top - $(this).height() + $e.height() > 0) && ($(this).scrollTop( $e[0].offsetTop - $(this).height() + $e.outerHeight() ));

Navigating long un-ordered list

I have this long list with overflow: auto to scroll through it, i set it up for keyboard navigation, the problem is that when using the keyboard it doesn't scroll correctly!
check this jsFiddle
$('ul').keydown(function (e) {
if (e.keyCode == 38) { // up
var selected = $(".selected");
$listItems.removeClass("selected");
if (selected.prev().length == 0) {
selected.siblings().last().addClass("selected");
} else {
selected.prev().addClass("selected");
}
}
if (e.keyCode == 40) { // down
var selected = $(".selected");
$listItems.removeClass("selected");
if (selected.next().length == 0) {
selected.siblings().first().addClass("selected");
} else {
selected.next().addClass("selected");
}
}
})
});
$listItems.click(function () {
if ($(this).is('.selected')) {
return true;
} else {
$('li').removeClass('selected');
$(this).addClass('selected');
}
the behavior i'm looking for is the same behavior of the element when scrolling through a long list of elements using the keyboard this plugin SelectBoxIt show's what i'm looking for.
you can use this code instead, i used animate function to navigate inside the div if the list exceed the width of the ul tag :
http://jsfiddle.net/goldendousa/p6243/13/
$('ul').focus(function() {
if ($('ul li').is('.selected')) {
$('ul li').first().removeClass('selected');
} else {
$('ul li').first().addClass('selected');
}
});
$('ul').keydown(function(e) {
if (e.keyCode == 38) { // up
e.preventDefault();
var selected = $(".selected");
$("ul li").removeClass("selected");
if (selected.prev().length == 0) {
selected.siblings().last().addClass("selected");
var selectedTopOffset = selected.siblings().last().offset().top;
$('div').animate({
scrollTop: selectedTopOffset
}, 200);
} else {
selected.prev().addClass("selected");
var selectedTopOffset = $("div").scrollTop() + selected.position().top - $("div").height()/2 + selected.height()/2;
$('div').animate({
scrollTop: selectedTopOffset
}, 200);
}
}
if (e.keyCode == 40) { // down
e.preventDefault();
var selected = $(".selected");
$("ul li").removeClass("selected");
if (selected.next().length == 0) {
selected.siblings().first().addClass("selected");
if (selected.siblings().first().offset().top < 0) {
$('div').animate({
scrollTop: selected.siblings().first().offset().top
}, 200);
}
} else {
selected.next().addClass("selected");
var selectedTopOffset = $("div").scrollTop() + selected.position().top - $("div").height()/2 + selected.height()/2;
$('div').animate({
scrollTop: selectedTopOffset
}, 200);
}
}
});
$('li').click(function() {
if ($(this).is('.selected')) {
return true;
} else {
$('li').removeClass('selected');
$(this).addClass('selected');
}
});
