jsp 自定义分页标签

 
sb.append("<a href='").append(url);
if (url.indexOf("?") == -1)
sb.append("?page=").append(result.getPage().getNextPage());
else
sb.append("&page=").append(result.getPage().getNextPage());

else
sb.append("&page=").append(result.getPage().getTotalPage());
linkParams(sb);
sb.append("'>").append("尾页").append("</a>");
}
sb
.append(" 跳转到:<select name='goToPage' onchange='javascript:goPage(this.value)'>");
int s = result.getPage().getTotalCount();
for (int i = 1; i <= s; i ) {
sb.append("<option value=").append(i);
if (Integer.parseInt(page) == i)
sb.append(" selected");
sb.append(">第").append(i).append("页</option>");
