8.2.2.1 Variables and Scopes
Variables can be defined within a GSP using the set tag:
Here we assign a variable called now
to the result of a GSP expression (which simply constructs a new java.util.Date
instance). You can also use the body of the <g:set>
tag to define a variable:
<g:set var="myHTML">
Some re-usable code on: ${new Date()}
</g:set>
The assigned value can also be a bean from the applicationContext:
<g:set var="bookService" bean="bookService" />
Variables can also be placed in one of the following scopes:
-
page
- Scoped to the current page (default) -
request
- Scoped to the current request -
flash
- Placed within flash scope and hence available for the next request -
session
- Scoped for the user session -
application
- Application-wide scope.
To specify the scope, use the scope
attribute:
<g:set var="now" value="${new Date()}" scope="request" />
