Form Scripts

In order to have actions performed in form scripts JS is used. The results of this style are instantaneous; it is the most preferred method and the most used. It is also highly adaptable to interact with various customer scenarios. Form scripts are used most for the following tasks:

Data Validation
Automation
Process enhancement and enforcement

To configure commands for the controls those are added to the ribbon command. There are three items that the ribbon command delineates:

Enabling rules
Displaying rules
Actions

Ribbon Command

It is possible to delineate at what point ribbon elements are enabled. The <EnableRule> (RibbonDiffXml) element is used as follows:

Use the /RuleDefinitions/EnableRules/EnableRule element to define rules controlling when the ribbon element should be enabled.
Use the /CommandDefinitions/CommandDefinition/EnableRules/EnableRule element to associate specific enable rules to a command definition.

It is possible to delineate at what point ribbon elements are displayed.

Use the /RuleDefinitions/DisplayRules/<DisplayRule> (RibbonDiffXml) element to define rules controlling when the ribbon element should be displayed.
Use the /CommandDefinitions/CommandDefinition/DisplayRules/<DisplayRule> (RibbonDiffXml) element to associate specific display rules to a command definition.

Also it is possible to delineate the actions performed by a ribbon control in a <CommandDefinition> (RibbonDiffXml) element together with rules that control whether the control is enabled or visible in the ribbon.

A ribbon control can perform two types of actions and may include multiple actions:

JavaScript Functions: A <JavaScriptFunction> (RibbonDiffXml) element references a function defined in a Script Web resource.
Open a URL: The ribbon opens a URL using the value from an Address attribute in the <Url> (RibbonDiffXml) element. Additional parameters can pass information about how query string parameters are passed and the mode in which the window opens.
