gotoPrevSibling (NotesViewNavigator - JavaScript™)

Examples

This button gets a level-1 category view entry by number where 1 is the first level-1 category entry and -1 is the last level-1 category entry.

// This view has categories and ends with a total
var nav:NotesViewNavigator = database.getView("By category and date").createViewNav();
if (nav.getCount() == 0) return;
// User enters a number in the input box bound to requestScope.query
var n:int = parseInt(requestScope.query);
if (isNaN(n) || n == 0) n = 1;
// For positive number, get the nth level-1 category where 1 is the first category
if (n > 0) {
	nav.gotoFirst();
	for (var i = 1; i < n; i++) {
		nav.gotoNextSibling();
	}
// For negative number, get the -nth level-1 category where -1 is the last category
} else {
	nav.gotoLast();
	nav.gotoPrevSibling();
	for (var i = -1; i > n; i--) {
		nav.gotoPrevSibling();
	}
}
entry = nav.getCurrent();
if (entry.isTotal()) entry = nav.getPrevSibling();
requestScope.status += "\n" + entry.getPosition(".") + " ";
requestScope.status += entry.getColumnValues().elementAt(entry.getIndentLevel());
