	switch p.Type {
	case simpagin.LEFT:
		if p.Number == 0 {
			return "<li class=\"disabled\"><span>&laquo;</span></li>"
		} else {
			return fmt.Sprintf("<li><a href=\"?p=%d\">&laquo;</a></li>", p.Number)
		}
	case simpagin.MIDDLE:
		if p.IsActive {
			return fmt.Sprintf("<li class=\"active\"><span>%d</span></li>", p.Number)
		} else {
			return fmt.Sprintf("<li><a href=\"?p=%d\">%d</a></li>", p.Number, p.Number)
		}

for _, page := range pg.PageList {
	fmt.Print(page)
}
fmt.Print(pg.RightPage)
