Using Essential JavaScript (EJ) controls with Visualforce

Visualforce is the component-based user interface framework for the Force.com platform by Salesforce.com. Syncfusion JavaScript components can be used to create attractive user interfaces within Visualforce. This article provides step by step instructions for creating a sample application hosted in Visualforce and using EJ controls.

Step 1: Create HTML application using EJ controls

Create an application using Syncfusion JavaScript controls.

Make sure that all HTML tags are closed. 

In the below link, HTML app for Customer Support Analysis can be downloaded. In this sample, we have used ejGrid and ejChart controls.

It includes HTML app and modified HTML file to be embedded with Visualforce page (Static files are referred from Static Resources).

Step 2: Make changes in EJ angular directives to make controls workable within Visualforce page

Consider the below code snippet of ejGrid. The attribute directives ej-grid, e-columns and e-column are needed for rendering the grid control. Since, the attributes are not assigned with any value, when you paste this code into Visualforce page, it will throw invalid markup exception.

So, as the below snippet, assign some dummy value for those attributes.

Step 3: Upload HTML app dependencies (CSS, JS, Images) into Static Resources

There are two ways we can refer static resources in Visualforce pages,                                             

1. Give CDN link for the resources - We can refer the direct online link
2. Upload all static files needed for application into Static Resources

Steps to upload files,

1. Create archive file (.zip, .jar) which includes all the required static files
2. Login into Salesforce site
3. Click on setup icon in the header

4. Click on Static Resources

5. Name the file and upload the archive file created earlier

6. Make changes in the static resource references in the HTML file. In the below code, we are referring resources from ‘staticcontent’ archive file (which we uploaded in previous step).

Step 4: Create new page

1. Click on Visualforce Pages

2. Name the page and paste the HTML we have designed into the markup editor

3. Save the page   

Step 5: View the page

Click on preview and you can see the designed page.
