Es5 getting started in EJ2 JavaScript Diagram control
13 Jun 202424 minutes to read
The Essential JS 2 for JavaScript (global script) is an ES5 formatted pure JavaScript framework which can be directly used in latest web browsers.
Component Initialization
The Essential JS 2 JavaScript components can be initialized by using either of the following ways.
- Using local script and style references in a HTML page.
- Using CDN link for script and style reference.
Using local script and style references in a HTML page
Step 1: Create an app folder my-diagram-app
for Essential JS 2 JavaScript components.
Step 2: You can get the global scripts and styles from the Essential Studio JavaScript (Essential JS 2) build installed location.
Syntax:
Script:
**(installed location)**/Syncfusion/Essential Studio/{RELEASE_VERSION}/Essential JS 2/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js
Styles:
**(installed location)**/Syncfusion/Essential Studio/{RELEASE_VERSION}/Essential JS 2/{PACKAGE_NAME}/styles/material.css
Example:
Script:
C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-diagrams/dist/global/ej2-diagrams.min.js
Styles:
C:/Program Files (x86)/Syncfusion/Essential Studio/15.4.30/Essential JS 2/ej2-diagrams/styles/material.css
Step 3: Create a folder my-diagram-app/resources
and copy/paste the global scripts and styles from the above installed location to my-diagram-app/resources
location.
Step 4: Create a HTML page (index.html) in my-diagram-app
location and add the Essentials JS 2 script and style references.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Essential JS 2</title>
<!-- Essential JS 2 material theme -->
<link href="resources/material.css" rel="stylesheet" type="text/css"/>
<!-- Essential JS 2 Diagram's global script -->
<script src="resources/ej2-diagrams.min.js" type="text/javascript"></script>
</head>
<body>
</body>
</html>
Step 5: Now, add the Diagram
element and initiate the Essential JS 2 Diagram
component in the index.html
by using following code
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Essential JS 2</title>
<!-- Essential JS 2 material theme -->
<link href="resources/material.css" rel="stylesheet" type="text/css"/>
<!-- Essential JS 2 Diagram's global script -->
<script src="resources/ej2-diagrams.min.js" type="text/javascript"></script>
</head>
<body>
<!-- Add the HTML <div> element -->
<div id="element">Diagram</div>
<script>
// initialize diagram component
var diagram = new ej.diagrams.Diagram();
// Render initialized diagram.
diagram.appendTo('#element')
</script>
</body>
</html>
Step 6: Now, run the index.html
in web browser, it will render the Essential JS 2 Diagram component.
Using CDN link for script and style reference
Step 1: Create an app folder my-diagram-app
for the Essential JS 2 JavaScript components.
Step 2: The Essential JS 2 component’s global scripts and styles are already hosted in the below CDN link formats.
Syntax:
Script:
http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js
Styles:
http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/styles/material.css
Example:
Script:
https://cdn.syncfusion.com/ej2/25.2.3/dist/ej2.min.js
Styles:
http://cdn.syncfusion.com/ej2/ej2-diagrams/styles/material.css
Step 3: Create a HTML page (index.html) in my-diagram-app
location and add the CDN link references. Now, add the Diagram
element and initiate the Essential JS 2 Diagram
component in the index.html by using following code.
ej.diagrams.Diagram.Inject(ej.diagrams.DataBinding, ej.diagrams.HierarchicalTree);
var data = [
{ Name: "Elizabeth", Role: "Director" },
{ Name: "Christina", ReportingPerson: "Elizabeth", Role: "Manager" },
{ Name: "Yoshi", ReportingPerson: "Christina", Role: "Lead" },
{ Name: "Philip", ReportingPerson: "Christina", Role: "Lead" },
{ Name: "Yang", ReportingPerson: "Elizabeth", Role: "Manager" },
{ Name: "Roland", ReportingPerson: "Yang", Role: "Lead" },
{ Name: "Yvonne", ReportingPerson: "Yang", Role: "Lead" }
];
var codes = {
Director: "rgb(0, 139,139)",
Manager: "rgb(30, 30,113)",
Lead: "rgb(0, 100,0)"
};
function getNodeTemplate(node) {
node.annotations[0].content = node.data.Name;
node.style.fill = codes[node.data.Role];
}
var items = new ej.data.DataManager(data, new ej.data.Query().take(7));
var diagram = new ej.diagrams.Diagram({
width: '100%', height: '350px',
mode: 'SVG', snapSettings: { constraints: ej.diagrams.SnapConstraints.None },
dataSourceSettings: {
id: 'Name', parentId: 'ReportingPerson', dataManager: items
},
layout: {
type: 'OrganizationalChart',
margin: { left: 10, top: 10 },
horizontalSpacing: 50,
verticalSpacing: 50,
orientation: 'TopToBottom',
getLayoutInfo: function (node, tree) {
if (!tree.hasSubTree) {
tree.orientation = 'Vertical';
tree.type = 'Alternate';
}
}
},
getNodeDefaults: function (obj, diagram) {
obj.height = 30;
obj.width = 70;
obj.shape = { type: 'Basic', shape: 'Rectangle' };
obj.annotations = [{
id: "label1",
style: {
fontSize: 11,
bold: true,
fontFamily: "Segoe UI",
color: "white"
}
}];
return obj;
},
getConnectorDefaults: function (connector, diagram) {
connector.targetDecorator.shape = 'Arrow';
connector.type = 'Orthogonal';
return connector;
},
setNodeTemplate: function (node) {
return getNodeTemplate(node);
}
});
diagram.appendTo('#element');

Step 4: Now, run the index.html
in web browser, it will render the Essential JS 2 Diagram
component.
Module Injection
The diagram component is divided into individual feature-wise modules. In order to use a particular feature, inject the required module. The following list describes the module names and their description.
-

});
diagram.appendTo('#element');
Basic Diagram elements
-
Node
: Visualizes any graphical object using nodes, which can also be arranged and manipulated on a diagram page. -
Connector
: Represents the relationship between two nodes. Three types of connectors provided as follows:
1) Orthogonal
2) Bezier
3) Straight
-
Port

Annotation
: Shows additional information by adding text or labels on nodes and connectors.
Flow Diagram
Create and add node to the diagram
Create and add a node
(JSON data) with specific position, size.
var nodes = [
{
id: 'Start', width: 140, height: 50, offsetX: 300, offsetY: 50,
}
];
var diagram = new ej.diagrams.Diagram({
width: '100%', height: '600px', nodes: nodes

</body></html>
Apply shape and style to node
Syncfusion diagram control provides support to render many build-in shapes in diagram.
Please refer to Shapes
to know about built-in Shapes.
- The appearance of a node can be customized by changing its
fill
color,strokeColor
,strokeWidth
,borderColor
,borderWidth
,strokeDashArray
,opacity
, andshadow
.
var nodes = [
{
id: 'Start', width: 140, height: 50, offsetX: 300, offsetY: 50,
annotations: [{
id: 'label1',
content: 'Start'
}],
shape: { type: 'Flow', shape: 'Terminator'},
//To define the shape of the node
shape: { type: 'Flow', shape: 'Terminator'},
//To define border style for the node.
borderColor:'orange',borderWidth:10,
//To define style for the node.
style:{fill:'red',strokeColor:'green',strokeWidth:5,strokeDashArray:'2 2'}
}
];
var diagram = new ej.diagrams.Diagram({
width: '100%', height: '600px', nodes: nodes
}, '#element');

Add other flowchart nodes to the diagram
You can add multiple nodes with different shapes into diagram.
var nodes = [
{
id: 'Start',
offsetY: 50,
annotations: [{ content: 'Start' }],
shape: { type: 'Flow', shape: 'Terminator' },
},
{
id: 'Init',
offsetY: 140,

shape: { type: 'Flow', shape: 'Process' },
},
{
id: 'Condition',
offsetY: 230,
annotations: [{ content: 'i < 10?' }],
shape: { type: 'Flow', shape: 'Decision' },
},
];
var diagram = new ej.diagrams.Diagram(
{
width: '100%',
height: '600px',
nodes: nodes,
getNodeDefaults: (node) => {
node.height = 50;
node.width = 140;

Connect flow chart nodes
Connect these nodes by adding a connector using the connectors
property of diagram and refer the source and target end by using the sourceID
and targetID
properties.
The required nodes and connectors can be added to form a complete flow diagram.
var nodes = [
{
id: 'Start',
offsetX: 300,
offsetY: 50,
annotations: [{ content: 'Start' }],
shape: { type: 'Flow', shape: 'Terminator' },

sourceID: 'Condition',
targetID: 'End',
annotations: [{ content: 'No' }],
type: 'Orthogonal',
segments: [
{ type: 'Orthogonal', length: 30, direction: 'Right' },
{ type: 'Orthogonal', length: 300, direction: 'Bottom' },
],
},

Default values for all nodes
and connectors
can be set using the getNodeDefaults
and getConnectorDefaults
properties, respectively. For example, if all nodes have the same width and height, such properties can be moved into getNodeDefaults
.
Automatic organization chart
In the ‘Flow Diagram’ section, how to create a diagram manually was discussed. This section explains how to create and position the diagram automatically.
Create Business object (Employee information)
Define Employee Information as JSON data. The following code example shows an employee array whose, Name
is used as an unique identifier and ReportingPerson
is used to identify the person to whom an employee report to, in the organization.
//Initialize data source...
let data = [{Name: "Elizabeth", Role: "Director" },
{ Name: "Christina", ReportingPerson: "Elizabeth", Role: "Manager" },
{ Name: "Yoshi", ReportingPerson: "Christina", Role: "Lead" },
{ Name: "Philip", ReportingPerson: "Christina", Role: "Lead" },
{ Name: "Yang", ReportingPerson: "Elizabeth", Role: "Manager" },
{ Name: "Roland", ReportingPerson: "Yang", Role: "Lead" },
{ Name: "Yvonne", ReportingPerson: "Yang", Role: "Lead" }
];
Map data source to diagram
You can configure the above “Employee Information” with diagram, so that the nodes and connectors are automatically generated using the mapping properties. The following code example show how dataSourceSettings
is used to map ID and parent with property name identifiers for employee information.
//Initialize data source...
let data = [
{ Name: 'Elizabeth', Role: 'Director' },
{ Name: 'Christina', ReportingPerson: 'Elizabeth', Role: 'Manager' },
{ Name: 'Yoshi', ReportingPerson: 'Christina', Role: 'Lead' },
{ Name: 'Philip', ReportingPerson: 'Christina', Role: 'Lead' },
{ Name: 'Yang', ReportingPerson: 'Elizabeth', Role: 'Manager' },
{ Name: 'Roland', ReportingPerson: 'Yang', Role: 'Lead' },
{ Name: 'Yvonne', ReportingPerson: 'Yang', Role: 'Lead' },
];
let items = new ej.data.DataManager(data, new ej.data.Query().take(7));
var diagram = new ej.diagrams.Diagram({
width: '100%',
height: '350px',
});
diagram.appendTo('#element');
Rendering layout with Datasource
To create an organizational chart, the type
of layout should be set as an OrganizationalChart
. The following code example shows how DataManager is used to generate Layout based on the DataSourceSettings of the Diagram.
ej.diagrams.Diagram.Inject(
ej.diagrams.DataBinding,
ej.diagrams.HierarchicalTree
);
var data = [
{ Name: 'Elizabeth', Role: 'Director' },
{ Name: 'Christina', ReportingPerson: 'Elizabeth', Role: 'Manager' },
{ Name: 'Yoshi', ReportingPerson: 'Christina', Role: 'Lead' },
{ Name: 'Philip', ReportingPerson: 'Christina', Role: 'Lead' },
{ Name: 'Yang', ReportingPerson: 'Elizabeth', Role: 'Manager' },
{ Name: 'Roland', ReportingPerson: 'Yang', Role: 'Lead' },
{ Name: 'Yvonne', ReportingPerson: 'Yang', Role: 'Lead' },
];
var codes = {
Director: 'rgb(0, 139,139)',
Manager: 'rgb(30, 30,113)',
Lead: 'rgb(0, 100,0)',
};
function getNodeTemplate(node) {
node.annotations[0].content = node.data.Name;
node.style.fill = codes[node.data.Role];
}
var items = new ej.data.DataManager(data, new ej.data.Query().take(7));
var diagram = new ej.diagrams.Diagram({
width: '100%',
height: '350px',
mode: 'SVG',
snapSettings: { constraints: ej.diagrams.SnapConstraints.None },
dataSourceSettings: {
id: 'Name',
parentId: 'ReportingPerson',
dataManager: items,
},
layout: {
type: 'OrganizationalChart',
margin: { left: 10, top: 10 },
horizontalSpacing: 50,
verticalSpacing: 50,
orientation: 'TopToBottom',
getLayoutInfo: function (node, tree) {
if (!tree.hasSubTree) {
tree.orientation = 'Vertical';
tree.type = 'Alternate';
}
},
},
getNodeDefaults: function (obj, diagram) {
obj.height = 30;
obj.width = 70;
obj.shape = { type: 'Basic', shape: 'Rectangle' };
obj.annotations = [
{
id: 'label1',
style: {
fontSize: 11,
bold: true,
fontFamily: 'Segoe UI',
color: 'white',
},
},
];
return obj;
},
getConnectorDefaults: function (connector, diagram) {
connector.targetDecorator.shape = 'Arrow';
connector.cornerRadius = 7;
connector.type = 'Orthogonal';

Customize employee appearance
The following code examples indicate how to define the default appearance of nodes and connectors. The setNodeTemplate
is used to update each node based on employee data.
