If Tag

The if tag implements a simple IF THEN conditional branch. It uses the following format:

<div od-if condition="business_service,business_service_method,argument1:value1,argument2:value2,..."> ... <!--od section if close–>

where:

• condition. Defines the condition.

• argument:value defines an argument and value pair.

If SWE evaluates the condition to:

• TRUE. It processes the body of the if tag.

• FALSE. It ignores the body of the if tag.

You can use the if tag with any business service, such as a custom business service that examines an HTTP header. The output arguments for this business service must contain a property that includes the name of the business service method and a value of 1 or 0 that indicates if the condition is true or false.

The predefined Web Engine State Properties business service supports the following conditions:

• IsEvenRow

• IsOddRow

• IsCurrentRow

• IsErrorRow

• IsRowMultipleOf

• IsRowPositionOf

• IsLastDisplayedRow

• IsHighInteractive

• IsHighInteractiveApplet

• IsLowInteractive

• Invalid
