tp5+jquery实现搜索后分页 

public function userLists(){
        $model = new User();
        $word = input('get.word');
        //接收当前页
        $page = input('get.page');
        $cpage = empty($page) ? 1 : $page;
        //设置每页显示的条数
        $length = 3;
        //获取总条数
        if(empty($word)){
            $count = $model->getCount();
        }else{
            $count = $model->getCount2($word);
        }

        //求出总页数
        $num_page = ceil($count/$length);
        //偏移量
        $limit = ($cpage-1)*$length;
        //查询
        if(empty($word)){
            $data = $model->getLists($limit,$length);
        }else{
            $data = $model->getLists2($limit,$length,$word);
        }

        $arr['word'] = empty($word) ? "" : $word;
        $arr['home'] = 1;
        $arr['prev'] = $cpage-1<=1 ? 1 : $cpage-1;
        $arr['next'] = $cpage+1>=$num_page ? $num_page : $cpage+1;
        $arr['last'] = $num_page;
        $arr['list'] = $data;
        return view('userLists',['arr'=>$arr]);
    }

模型层代码：


//总条数
    public function getCount(){
        return $this->count();
    }

    public function getCount2($word){
        return $this->where('username','like',"%$word%")->count();
    }
    //分页查询
    public function getLists($limit,$length){
        return $this->limit($limit,$length)->select();
    }
    public function getLists2($limit,$length,$word){
        return $this->where('username','like',"%$word%")->limit($limit,$length)->select();
    }

静态页代码：

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>
<body>
<input type="text" name="word" value="{$arr.word}">
<input type="button" value="搜索" onclick="page(1)">
<table border="1">
    <tr>
        <td>主键</td>
        <td>用户名</td>
        <td>手机</td>
        <td>邮箱</td>
        <td>地址</td>
    </tr>

    {volist name="arr.list" id="v"}
        <tr>
            <td>{$v.id}</td>
            <td>{$v.username}</td>
            <td>{$v.tel}</td>
            <td>{$v.email}</td>
            <td>{$v.address}</td>
        </tr>
    {/volist}
</table>

<a href="javascript:void(0)" onclick="page({$arr.home})">首页</a>
<a href="javascript:void(0)" onclick="page({$arr.prev})">上一页</a>
<a href="javascript:void(0)" onclick="page({$arr.next})">下一页</a>
<a href="javascript:void(0)" onclick="page({$arr.last})">尾页</a>
</body>
</html>
<script src="__STATIC__/js/jq.js"></script>
<script>
    function page(obj) {
        var word = $("input[name='word']").val();
        $.get("{:url('Testone/userLists')}?page="+obj+"&word="+word,function (data) {
            $("body").html(data);
        })
    }
</script>
