控制器

<?php

namespace Home\Controller;

use Think\Controller;

class AjaxController extends Controller

{

    public function test()

    {

        $this->display();

    }

    public function xianshi()

    {

        $n = D("Nation");

        $attr = $n->select();

        $this->ajaxReturn($attr); //ajax返回方法

    }

    public function tianjia()

    {

        $this->display();

    }

    public function tianjiachuli()

    {

        $n = D("Nation");

        $n->create();

        $r = $n->add();

        if($r)

        {

            $this->ajaxReturn("OK","eval");

        }

        else{

            $this->ajaxReturn("NO","eval");

        }

    }

}
