TP ajax

①Ajax使用:   注意传值的所有过程用的是小写,及时数据库列的名称中有大写字母

控制器部分:

AjaxController.class.php

<?php 
namespace HomeController;
use ThinkController;
class AjaxController extends Controller
    {

        public function Ajax(){

            if (empty($_POST)) {
                $this->display();
            }
            else{
                $code=$_POST["code"];
                $nation=D('nation');
                $attr=$nation->find($code);
                $name=$attr["name"];
                $this->ajaxReturn($name,'eval');

            }
        } 


    }

②Ajax.html 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
    <script src="../../../../../jquery-1.11.2.min.js"></script>
</head>
<body>

<input type="text" id="code"></input>
    <!-- <input type="button" value="显示" id="test"></input> -->    
<span id="xianshi"></span>
<form>
<input type="text" required="required"></input>
<input type="submit" value="提交"></input>
</form>
</body>
</html>
<script type="text/javascript">
    $(document).ready(function(e){
        
        $("#code").blur(function(){
            //alert($);
            var code=$('#code').val();
            $.ajax({
                url:"__SELF__",
                data:{code:code},
                type:"POST",
                dataType:"TEXT",
                success:function(data){
                    //alert(data);
                    $("#xianshi").html(data);
                }
            })
        })
    });
</script>
