"; $("#currentPage").val(curPage); if(page <= totalPage){ if(datas <= 10){ for(i=1; i<=datas; i++){ //为当前页增加样式 var active =""; if(i==curPage){ active=" class='active' "; } liStr +=" "+i+"
" } }else{ var start =pageSize*(page-1)+1; var end =page*pageSize; if(page == totalPage){ for(i=start; i<=datas; i++){ //为当前页增加样式 var active =""; if(i==curPage){ active=" class='active' "; } liStr +=" "+i+"
" } }else{ for(i=start; i<=end; i++){ //为当前页增加样式 var active =""; if(i==curPage){ active=" class='active' "; } liStr +=" "+i+"
