本文实例讲述了thinkPHP3.2.3结合Laypage实现的分页功能。分享给大家供大家参考，具体如下：
控制器
<?php
namespace Home\Controller;
use Think\Controller;
class IndexController extends Controller {
/**
*@brief 查询
****/
public function index(){
$choose = I('choose','-6');
$c['easy_hard'] = $choose;
$type=I('typeid','');
$nowpage=I('page',1);
if($type == '')
{
if($choose == -6)
{
$totalpage=ceil((D('data')->count())/10);
$infos=D('data')->limit(($nowpage-1)*10,10)->select();
}else{
$totalpage=ceil((D('data')->where($c)->count())/10);
$infos=D('data')->where($c)->limit(($nowpage-1)*10,10)->select();
}
}else{
if($choose == -6)
{
$map['data'] = array('like',"%$type%");
$totalpage=ceil((D('data')->where($map)->count())/10);
$infos=D('data')->where($map)->limit(($nowpage-1)*10,10)->select();
}else{
$map['data'] = array('like',"%$type%");
$totalpage=ceil((D('data')->where($map)->where($c)->count())/10);
$infos=D('data')->where($map)->where($c)->limit(($nowpage-1)*10,10)->select();
}
}
$this->assign('type',$type);
$this->assign('choose',$choose);
$this->assign("totalpage",$totalpage);
$this->assign("infos",$infos);
$this -> display();
}
}
视图层

var checkValue=$("#slc1").val();
window.location.href="?typeid=" rel="external nofollow" rel="external nofollow" +type+"&choose="+checkValue;
}
$("#sou").bind("click",function(event){
var type=$("#type").val();//获取假设的搜索条件值
var checkValue=$("#slc1").val();
window.location.href="?typeid=" rel="external nofollow" rel="external nofollow" +type+'&choose='+checkValue;
});
$(function(){
laypage({
cont: 'page11',
pages: {$totalpage}, //假设我们获取到的是18（后端计算完总页数后将总页数值传过来，放在这里即可（类似{$totalpage}））.
curr: function(){ //通过url获取当前页，也可以同上（pages）方式获取
var page = location.search.match(/page=(\d+)/);
return page ? page[1] : 1;//如果没有页数显示时，默认是第一页
}(),
jump: function(e, first){ //触发分页后的回调
if(!first){ //一定要加此判断，否则初始时会无限刷新
location.href=setParam("page",e.curr);
}
}
});
});
function setParam(param,value){
var query = location.search.substring(1);
var p = new RegExp("(^|)" + param + "=([^&]*)(|$)");
if(p.test(query)){
//query = query.replace(p,"$1="+value);
var firstParam=query.split(param)[0];
var secondParam=query.split(param)[1];
if(secondParam.indexOf("&")>-1){
var lastPraam=secondParam.split("&")[1];
return '?'+firstParam+'&'+param+'='+value+'&'+lastPraam;
}else{
if(firstParam){
return '?'+firstParam+''+param+'='+value;
}else{
return '?'+param+'='+value;
}
}
}else{
if(query == ''){
return '?'+param+'='+value;
}else{
return '?'+query+'&'+param+'='+value;
}
}
}
</script>
</body>

希望本文所述对大家基于ThinkPHP框架的PHP程序设计有所帮助。
