<script src="path/to/jkanban.min.js"></script>

in your page and you are done.

Usage

Init jKanban is a piece of cake!

var kanban = new jKanban(options)

Here’s an overview of the default values.

var kanban = new jKanban({
    element          : '',                                           // selector of the kanban container
    gutter           : '15px',                                       // gutter of the board
    widthBoard       : '250px',                                      // width of the board
    responsivePercentage: false,                                    // if it is true I use percentage in the width of the boards and it is not necessary gutter and widthBoard
    dragItems        : true,                                         // if false, all items are not draggable
    boards           : [],                                           // json of boards
    dragBoards       : true,                                         // the boards are draggable, if false only item can be dragged
    addItemButton    : false,                                        // add a button to board for easy item creation
    buttonContent    : '+',                                          // text or html content of the board button
    itemHandleOptions: {
        enabled             : false,                                 // if board item handle is enabled or not
        handleClass         : "item_handle",                         // css class for your custom item handle
        customCssHandler    : "drag_handler",                        // when customHandler is undefined, jKanban will use this property to set main handler class
        customCssIconHandler: "drag_handler_icon",                   // when customHandler is undefined, jKanban will use this property to set main icon handler class. If you want, you can use font icon libraries here
        customHandler       : "<span class='item_handle'>+</span> %s"// your entirely customized handler. Use %s to position item title
    },
    click            : function (el) {},                             // callback when any board's item are clicked
    dragEl           : function (el, source) {},                     // callback when any board's item are dragged
    dragendEl        : function (el) {},                             // callback when any board's item stop drag
    dropEl           : function (el, target, source, sibling) {},    // callback when any board's item drop in a board
    dragBoard        : function (el, source) {},                     // callback when any board stop drag
    dragendBoard     : function (el) {},                             // callback when any board stop drag
    buttonClick      : function(el, boardId) {}                      // callback when the board's button is clicked
})

Now take a look to the boards object

[
    {
        "id"    : "board-id-1",               // id of the board
        "title" : "Board Title",              // title of the board
        "class" : "class1,class2,...",        // css classes to add at the title
        "dragTo": ['another-board-id',...],   // array of ids of boards where items can be dropped (default: [])
        "item"  : [                           // item of this board
            {
                "id"    : "item-id-1",        // id of the item
                "title" : "Item 1"            // title of the item
                "class" : ["myClass",...]     // array of additional classes
            },
            {
                "id"    : "item-id-2",
                "title" : "Item 2"
            }
        ]
    },
    {
        "id"    : "board-id-2",
        "title" : "Board Title 2"
    }
]

WARNING: all ids are unique!

About custom properties

jKanban also support custom properties on items to improve your applications with html data- properties. You can define them at like:

[
    {
        "id"    : "board-id-1",
        "title" : "Board Title",
        "item"  : [
            {
                "id"      : "item-id-1",
                "title"   : "Item 1",
                "username": "username1"
            },
            {
                "id"      : "item-id-2",
                "title"   : "Item 2",
                "username": "username2"
            }
        ]
    }
]

Which jKanban will convert to:

<main class="kanban-drag">
    <div class="kanban-item" data-eid="item-id-1" data-username="username1">Item 1</div>
    <div class="kanban-item" data-eid="item-id-2" data-username="username2">Item 2</div>
</main>

What is JavaScript - Stackfindover - Blog

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.

Who invented JavaScript?

JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.

What is JavaScript?

JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.

Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.

JavaScript Hello World Program

In JavaScript, ‘document.write‘ is used to represent a string on a browser.

<script type="text/javascript">
	document.write("Hello World!");
</script>

How to comment JavaScript code?

  • For single line comment in JavaScript we have to use // (double slashes)
  • For multiple line comments we have to use / * – – * /
<script type="text/javascript">

//single line comment

/* document.write("Hello"); */

</script>

JavaScript Memory Management System

The main goal of this article is to help to readers to understand how memory management system performs in JavaScript.

I will use a shorthand such as GC which means Garbage Collection. When the browsers use Javascript, they need any memory location to store objects, functions, and all other things. Let’s deep in dive that how things going to work in GC.

Image for post

The JavaScript Engine’s Garbage collector’ looks out for objects which are unreachable and also removed from the memory.

So I will share an example below and show you steps that will be needed to work with GC.

var number = 50;                // allocates memory for a number

var string = 'textual data';  // allocates memory for a string
var object = {x: 10};         // allocates memory for an object
var x= [10, null, 'abra'];     // allocates memory for the array
function f(x) {               // allocates memory for a function
return x * 2;
}                              

The example shows how JavaScript allocates memory for the variables when they declare. But when the memory is no longer needed, the allocated memory will be released. GC finds the memory no longer used by the application and releases it. But the main question is that how GC finds the memory no longer used?

The basic algorithm for doing that is called “mark-and-sweep”.
