WOConditional
Element Description
A WOConditional object controls whether a portion of the HTML page will be generated, based on the evaluation of its assigned condition.
Synopsis
WOConditional { condition=aBoolean; [negate=aBoolean;] ... };
Bindings
- condition
- If condition evaluates to
YES
ortrue
, and assuming that negate isn't in effect, the HTML code controlled by the WOConditional object is emitted; otherwise it is not.
- negate
- Inverts the sense of the condition. By default, negate is
assumed to be
false
orNO
.
Example
The negate attribute lets you use the same test to display mutually exclusive information; for example:
HTML file:
<HTML> <WEBOBJECTS NAME="PAYING_CUSTOMER">Thank you for your order!</WEBOBJECTS> <WEBOBJECTS NAME="WINDOW_SHOPPER">Thanks for visiting!</WEBOBJECTS> </HTML>
Declarations File:
PAYING_CUSTOMER: WOConditional {condition=payingCustomer;}; WINDOW_SHOPPER: WOConditional {condition=payingCustomer; negate=YES;};
Script File:
- payingCustomer { if (/* ordered something */) { return YES; } return NO; }
