This creates a footer for a search page containing a column of checkboxes.
Typically this is used to select several items from the search result and
apply some change to all of them at once. The footer always provides
"select all" and "unselect all" buttons.
"actions" is an arrayref of action buttons to show. Each element of the
array is a hashref of either:
- "submit" and, optionally, "confirm". Creates a submit button. The value
of "submit" becomes the "value" property of the button (and thus its label).
If "confirm" is specified, the button will have an onclick handler that
displays the value of "confirm" in a popup message box and asks the user to
confirm the choice. The hashref may also have a "name" property, which
sets the name of the submit button.
- "onclick" and "label". Creates a non-submit button that executes the
Javascript code in "onclick". "label" is used as the text of the button.
If you want only a single action, you can forget the arrayref-of-hashrefs
business and just put "submit" and "confirm" (or "onclick" and "label")
elements in the argument list.
"filter" is a javascript expression to limit which checkboxes are included in
the "select/unselect all" actions. By default, any input with type="checkbox"
will be included. If this option is given, it will be evaluated with the
HTML node in a variable named "obj". The expression should return true or
false.
