[Object {id="1", name="Muslin", image1="muslin.jpg"}, Object {id="72", name="Gagra choli", ...}]

这是我在 php 中使用 json_encode 得到的 json 输出。当我实现它时，它说无效的json，为什么？

我用这个实现了json

编辑：这是控制器：

function show_data()
{
        $this->load->model("elements_model");
        echo json_encode($this->elements_model->get_all());

}

这是模型：

<?php
class Elements_model extends CI_Model
{
function __construct(){
    parent::__construct();
}
public function insert_elements($data)
{
    return $this->db->insert('elements',$data);
}
public function get_all()
{
    $sql = 'SELECT * FROM elements';
            $query = $this->db->query($sql);
            // Fetch the result array from the result object and return it
            return $query->result();
}
}

这是视图

<html>
<head>
    <title> ajax call first time </title>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">        </script> 
    <script type="text/javascript">
    $(document).ready(function(){
        //alert("hello");
        $.ajax({
            type:'POST',
            dataType: "json", 
            url:'elements/show_data',
            success:function(res){
            console.log(res);
                            //var obj=$.parseJSON(res);
                                $('#response').html("obj.name");
                                //$('#response').show();
            },
            error:function(xhr,status,error)
            {
                $('#response').html(xhr.responseText);
            }
        });
    });
    </script>
</head>
<body>
<div class="response" id="response" ></div>
<div class="container" id="container" ></div>
</body>

这是console.log

[{"id":"1","name":"Muslin","image1":"muslin.jpg"},{"id":"72","name":"Gagra choli","image1":"gagra choli.jpg"},{"id":"73","name":"Lahenga saree","image1":"lahenga saree.jpg"},{"id":"74","name":"Ao dai","image1":"Ao dai.jpg"},{"id":"75","name":"Brocade","image1":"brocade.jpg"},{"id":"77","name":"Button","image1":"button.jpg"},{"id":"78","name":"Bathrobe","image1":"Bathrobe.jpg"},{"id":"79","name":"Bathtowel","image1":"Bathtowel.jpg"},{"id":"80","name":"Cassock","image1":"cassock.jpg"},{"id":"81","name":"Shirt","image1":"shirt.jpg"},{"id":"82","name":"Dolce and Gabanna","image1":"dolce_and_gabanna.jpg"},{"id":"83","name":"asasa","image1":"1009578_1392050054339713_1292927121_o.jpg"},{"id":"84","name":"knbdfjhbjhbvjh","image1":"images_(1)10.jpg"}]

我更新了 console.log
