JQuery Data table is way of present our data at client
side and we can show case data and we can perform operations like sorting, update,
page nation and many other operations we can perform on data table.
JQuery Data table is very popular jQuery plugin which built
it on top of JQuery library. JQuery Data table have very good community and
plenty of example so that we can use and integrate to our applications.
The
following is reference URL
Liferay have search container to display data and make
pagination and sorting apart from if you want use some other data gird/data
table then JQuery data table is best choice and we can better support and many examples available.
As we know that JQuery Data table have used JQuery
Java script library and its one of plugin for JQuery.
When we want integrate JQuery Data table we need JQuery Core library java scrip, Data table Plugin and Data table required
CSS.
Download
Liferay JQuery Data Table Portlet
The
following are minimum required files.
JavaScript
Files
jquery-1.11.1.min.js
jquery.dataTables.min.js
CSS
Files
jquery.dataTables.css
Note:
Above
specified files available in direct at CDN point we can use those reference
or we directly put in our application then refer them, either way is fine.
|
JQuery Data Table have many examples all example
available in the following URL
Down load all Data table related files
JQuery Data table developed with minimum required
needs apart from that it we want enable out of box features then we have data
table extension and data
table plugins. When we use these then we will get additional
capabilities for data tables.
JQuery Data table have API document there we can see
all properties and methods which are available in data table.

JQuery Data table have rich set of methods and
Properties from these we can full fill our need in the development of
applications.
In this post I will take some examples from JQuery Data
table and make it work in Liferay Portlet.
Simple
Data Table
Load
Data in Data Table Using Ajax
Hidden
Data Table Columns
Simple
Data Table
Simple data table we simply get data from data and present
in the JSP page. Here we need to add required JS and CSS files. I already added
JS and CSS files in portlet so we simply refer ethos files.
Simple
Data Table Example
<%@page import="com.liferay.portal.model.User"%>
<%@page import="com.liferay.portal.service.UserLocalServiceUtil"%>
<%@include file="init.jsp" %>
<script src="<%=renderRequest.getContextPath()%>/js/jquery-1.11.1.min.js"></script>
<script src="<%=renderRequest.getContextPath()%>/js/jquery.dataTables.min.js"></script>
<link rel="stylesheet" href="<%=renderRequest.getContextPath()%>/css/jquery.dataTables.css">
<style>
.message-container{
padding:10px;
margin:2px;
display:none;
background: rgba(128,
128, 128, 0.33);
border: 1px
solid #0A0A0C;
}
</style>
<h2>Simple
Jquery Data Table with Zero Configuration</h2>
<%
List<User>
userList=UserLocalServiceUtil.getUsers(-1,-1);
%>
<c:if test="<%=userList!=null&&!userList.isEmpty() %>">
<table id="userTable" class="display" cellspacing="0"
width="100%">
<thead>
<tr>
<th>User

<%for(User
curUser:userList){ %>

$(document).ready(function() {
$('#userTable').DataTable();

<c:if test="<%=Validator.isNull(userList)||userList.isEmpty()%>">
<div class="message-container">No data to Display</div>
</c:if>

Load
Data in Data Table Using Ajax
In this example we will use Ajax call to Portlet
server resource method there we will prepare JSON data as for data table
required format so that data will be loaded in the table.
Data
as Array
Data
Table Java Script
$(document).ready(function()
{
$(document).ready(function() {
$('#userTable').dataTable( {
"ajax":
"<%=usersArrayURL%>"
} );
} );
}
);
Data
Format
{
"data":[
[
20199,
"joebloggs",
"Joe",
"Bloggs",
"test@liferay.com",
""
],
[
20536,
"ord1",
"Test",
"ORD 1",
"test.ord.1@liferay.com",
""
],
[
20543,
"ord2",
"Test",
"ORD 2",
"test.ord.2@liferay.com",
""
],
[
20550,
"ord3",
"Test",
"ORD 3",
"test.ord.3@liferay.com",
""
]
]
}
|
Data
as Array of Objects
Here data is array of user objects and this will be referred
by key “data” in the object.
Data
Table Java Script
$(document).ready(function()
{
$('#userTable').dataTable( {
"ajax":
"<%=usersObjectArrayURL%>",
"columns": [
{ "data":
"userId" },
{ "data":
"screeName" },
{ "data":
"firstName" },
{ "data":
"lastName" },
{ "data":
"email" },
{ "data":
"jobTitle" }
]
} );
} );
Data
Format
{
"data":[
{
"lastName":"Bloggs",
"email":"test@liferay.com",
"screeName":"joebloggs",
"userId":20199,
"firstName":"Joe",
"jobTitle":""
},
{
"lastName":"ORD
1",
"email":"test.ord.1@liferay.com",
"screeName":"ord1",
"userId":20536,
"firstName":"Test",
"jobTitle":""
},
{
"lastName":"ORD
2",
"email":"test.ord.2@liferay.com",
"screeName":"ord2",
"userId":20543,
"firstName":"Test",
"jobTitle":""
},
{
"lastName":"ORD
3",
"email":"test.ord.3@liferay.com",
"screeName":"ord3",
"userId":20550,
"firstName":"Test",
"jobTitle":""
}
]
}
|
Flat
Data
In this example data will be like array of user objects
and in the scrip we need to specify the column names and these should match to JSON
object keys.
Data
Table Java Script
$(document).ready(function()
{
$('#userTable').dataTable( {
"ajax": {
"url":"<%=usersFlatDataSourceURL%>",
"dataSrc": ""
},
"columns": [
{ "data":
"userId" },
{ "data":
"screeName" },
{ "data":
"firstName" },
{ "data":
"lastName" },
{ "data":
"email" },
{ "data":
"jobTitle" }
]
} );
} );
Data
Format
[
{
"lastName":"Bloggs",
"email":"test@liferay.com",
"screeName":"joebloggs",
"userId":20199,
"firstName":"Joe",
"jobTitle":""
},
{
"lastName":"ORD 1",
"email":"test.ord.1@liferay.com",
"screeName":"ord1",
"userId":20536,
"firstName":"Test",
"jobTitle":""
},
{
"lastName":"ORD 2",
"email":"test.ord.2@liferay.com",
"screeName":"ord2",
"userId":20543,
"firstName":"Test",
"jobTitle":""
},
{
"lastName":"ORD 3",
"email":"test.ord.3@liferay.com",
"screeName":"ord3",
"userId":20550,
"firstName":"Test",
"jobTitle":""
}
]
|
Custom
Data Source Property
Here we will refer our data as “mytabledata” key in JSON object same key we have to use in the
script for property “dataSrc”
Data
Table Java Script
$(document).ready(function()
{
$('#userTable').dataTable( {
"ajax": {
"url":"<%=usersCustomDataSourceURL%>",
"dataSrc": "mytabledata"
},
"columns": [
{ "data":
"userId" },
{ "data":
"screeName" },
{ "data":
"firstName" },
{ "data":
"lastName" },
{ "data":
"email" },
{ "data":
"jobTitle" }
]
} );
} );
Data
format
{
"mytabledata":[
{
"lastName":"Bloggs",
"email":"test@liferay.com",
"screeName":"joebloggs",
"userId":20199,
"firstName":"Joe",
"jobTitle":""
},
{
"lastName":"ORD
1",
"email":"test.ord.1@liferay.com",
"screeName":"ord1",
"userId":20536,
"firstName":"Test",
"jobTitle":""
},
{
"lastName":"ORD
2",
"email":"test.ord.2@liferay.com",
"screeName":"ord2",
"userId":20543,
"firstName":"Test",
"jobTitle":""
},
{
"lastName":"ORD
3",
"email":"test.ord.3@liferay.com",
"screeName":"ord3",
"userId":20550,
"firstName":"Test",
"jobTitle":""
}
]
}

Hidden
Data Table Columns
Sometime data we may have many columns but some of
columns you want hidden while display in table that we can do with following
script and we need specify the columns index that you are going to hide.
Html
<table
id="userTable" class="display" cellspacing="0"
width="100%">
<thead>
<tr>
<th>User Id</th>
<th>Screen
Name</th>
<th>First
Name</th>
<th>Last
Name</th>
<th>Email
Address</th>
<th>Job Title</th>
</tr>
</thead>
<tfoot>
<tr>
<th>User Id</th>
<th>Screen
Name</th>
<th>First
Name</th>
<th>Last
Name</th>
<th>Email
Address</th>
<th>Job
Title</th>
</tr>
</tfoot>
</table>
Java
Script
$(document).ready(function()
{
$('#userTable').dataTable( {
"ajax":
"<%=usersObjectArrayURL%>",
"columns": [
{ "data":
"userId" },
{ "data":
"screeName" },
{ "data":
"firstName" },
{ "data":
"lastName" },
{ "data":
"email" },
{ "data":
"jobTitle" }
],
"columnDefs": [
{
"targets": [ 0 ],
"visible": false,
"searchable": false
},
{
"targets": [ 5 ],
"visible": false
}
]
} );
} );
