The JavaScript API exposed through Visualize.js allows you to embed and dynamically interact with reports. With Visualize.js, you can create web pages and web applications that seamlessly embed reports and complex interaction. You can control the look and feel of all elements through CSS and invent new ways to merge data into your application. Visualize.js helps you make advanced business intelligence available to your users.
This chapter contains the following sections:
• | Requesting the Visualize.js Script |
• | Contents of the Visualize.js Script |
• | Usage Patterns |
Each function of Visualize.js is then described in the following chapters:
• | API Reference - login and logout |
• | API Reference - resourcesSearch |
• | API Reference - report |
• | API Reference - inputControls |
The last chapters demonstrate more advanced usge of Visualize.js:
• | API Usage - Report Events |
• | API Usage - Hyperlinks |
• | API Usage - Interactive Reports |
• | Visualize.js Tools |
Requesting the Visualize.js Script
The script to include on your HTML page is named visualize.js. It is located on your running instance of JasperReports Server. Later on your page, you also need a container element to display the report from the script.
The content of visualize.js is type='text/javascript', but that is the default so you usually don't need to include it.
You can specify several parameters when requesting the script:
Parameter | Type | Description |
---|---|---|
userLocale | locale string | Specify the locale to use for display and running reports. It must be one of the locales supported by JasperReports Server. The default is the locale configured on the server. |
logEnabled | true|false | Enable or disable logging. By default, it is enabled (true). |
logLevel | debug|info|warn|error | Set the logging level. By default the level is error. |
baseUrl | URL | The URL of the JasperReports Server that will respond to visualize requests. By default, it is the same server instance that provides the script. |
_opt | true|false | When true, the Javascript is optimized (reduced in size). By default, this parameter is false. |
The following request shows how to use script parameters:
<script src="http://bi.example.com:8080/jasperserver-pro/client/ visualize.js?userLocale=fr&logLevel=debug"></script>[/code] |
Contents of the Visualize.js Script
The Visualize.js script itself is a factory function for an internal JrsClient.
You write JavaScript in a callback that controls what the client does. The following code sample shows the functions of the JrsClient that are available to you:
These functions are described in the remaining API reference chapters.
Usage Patterns
After specifying the authentication information, you write the callback that will execute inside the client provided by visualize.js.
If you prefer, you can use the deferred pattern instead of the callback:
