public class CheckboxTag
- extends AbstractSingleCheckedElementTag
Databinding-aware JSP tag for rendering an HTML 'input
'
element with a 'type
' of 'checkbox
'.
May be used in one of three different approaches depending on the
type of the bound value
.
Approach One
When the bound value is of type Boolean
then the 'input(checkbox)
'
is marked as 'checked' if the bound value is true
. The 'value
'
attribute corresponds to the resolved value of the value
property.
Approach Two
When the bound value is of type Collection
then the 'input(checkbox)
'
is marked as 'checked' if the configured value
is present in
the bound Collection
.
Approach Three
For any other bound value type, the 'input(checkbox)
' is marked as 'checked'
if the the configured value
is equal to the bound value.
