Basic usage

Installation

Via npm:

Run in your console: npm install dynamic-paginator

, and Attach paginator styledynamic-paginator.css to the view page:

<link  rel="stylesheet"  href="//cdn.jsdelivr.net/npm/medium-editor@latest/dist/dynamic-paginator.css"  type="text/css"  media="screen"  charset="utf-8">

Via an external CDN

Using jsDelivr.

For the latest version:

<script  src="https://cdn.jsdelivr.net/gh/alameenlr/dynamic-paginator@latest/dist/dynamic-paginator.min.js"></script>

For a custom one:

<script  src="https://cdn.jsdelivr.net/gh/alameenlr/dynamic-paginator@1.0.0/dist/dynamic-paginator.min.js"></script>

Basic Usage

The next step is to reference the dynamic-paginator's script

<script  src="js/dynamic-paginator.min.js"></script>
...
<body>
	<div  id="dynamic-paginate-elm"></div>
	...
</div>

You can now instantiate a new DynamicPaginator object:

var dpOption = {
	search:false,
	loadListURL:"http://127.0.0.1:8000/invoices/list",
	itemProperties:[
		{"key":"id", "label":"Id"},
		{"key":"name", "label":"Name"},
		{"key":"emailid", "label":"Email Address"},
		{"key":"address", "label":"Address"},
		{"key":"date", "label":"Date"},
		{"key":"phone_number", "label":"Phone No"}
	],
	indexedItemPropertiesKeys:["id","name","emailid","address","phone_number"],
	items:[],
	totalItemsCount:10000,
	countsPerPage:10,
	currentViewValues:{
		pageNo:1
	},
	paginationBlock:{
		jumpTo:true
	},
	userParamListner:false,
}
let  element = document.getElementById("dynamic-paginate-elm");
var pg_list = new  DynamicPaginator(element ,dpOption);

or, You can also pass a list of HTML elements:

var pg_list = new  MediumEditor("#dynamic-paginate-elm",dpOption);

The above code will create a full pagination element based on the viewTemplate, you can customize the view template.

Integrating pagination with back-end

loadListURL - DynamicPaginator will send a POST with content-type: application/x-www-form-urlencoded request for every user request. It will reduce loading time save your server bandwidth.

Request Body:

//This is a sample in JSON, actual request is x-www-form-urlencoded
{
	"page-no":20,
	"offset":190,
	"count":10,
	"order-by":"name",
	"order-by-in":"asc",
}

Dynamic Paginator Options

Options to customize dynamic-paginator are passed as the second argument to the DynamicPaginator constructor. Example:

var paginator = new DynamicPaginator('#pagination-content', {
    // search
    // colorTheme
    // getInfoURL
    // loadListURL
    // itemsNumber
    // httpRequestHeaders
    // itemProperties
    // indexedItemPropertiesKeys
    // items
    // maxPagerNumbers
    // totalItemsCount
    // setCountsPerPage
    // pushToHistory
    // showViewingStatus
    // currentViewValues
    // fromStartOnSort
    // dpParamKeys
    // clientSideSearch
    // clientSideSearchFormat
    // userParamListner
