function renderPaging(url,curPage,totalPage)
{
var pageBarNum = 5;
var pageStr = '';
var gurl = function(num){
return url.replace('-page-',num);
};
curPage = parseInt(curPage);
totalPage = parseInt(totalPage);
if(curPage > 1){
pageStr += '<span class="grey-12"><< <a class="paging-per" href="' + gurl(curPage-1) + '">上一页</a> </span>';
}
var index = Math.floor(pageBarNum/2);
var start = (curPage-index)>0 ? (curPage-index) : 1;
var end = curPage + (pageBarNum-index);
end = end<pageBarNum ? pageBarNum : end;
if(start > 1){
pageStr += '<span class="grey-12"> <a class="paging-per" href="' + gurl(1) + '">1</a> </span>';
}
if(start > 2){pageStr += '<span class="grey-12"> ... </span>';}
for(var i=start; i<end; i++){
if(i>totalPage) break;
if(i == curPage){
pageStr += '<span class="blue-12-bold"> <a class="paging-per paging-current" href="' + gurl(i) + '">' + i + '</a> </span>';
}else{
pageStr += '<span class="grey-12"> <a class="paging-per" href="' + gurl(i) + '">' + i + '</a> </span>';
}
}
if(end < totalPage){
pageStr += '<span class="grey-12"> ... </span>';
pageStr += '<span class="grey-12"> <a class="paging-per" href="' + gurl(totalPage) + '">' + totalPage + '</a> </span>';
}
if(curPage < totalPage){
pageStr += '<span class="grey-12"> <a class="paging-per" href="' + gurl(curPage+1) + '">下一页</a> >></span>';
}
return pageStr;
}
后端只需要 传入 3个参数即可 $pager = array(
'pagecount' => ceil($counter / $numPerPage),
'url' => 'url.php/page/-page-'
'page' => $cur_page,
);
$this->_view['pager'] = $pager;
demo: <p id="pageBar" page="<?php echo $pager['page'];?>" pagecount="<?php echo $pager['pagecount'];?>" url="<?php echo $pager['url'];?>"></p>

JS分页，对搜索引擎不友好，分页将不能被爬虫检索。
