某些值的Jquery img src属性未出现

这是一个codeigniter+jquery问题。。。可能是noob但请原谅我。。。 我有这个模型：

function get_base_photo($model_selected) {
    if ($model_selected != NULL) {
        $this - > db - > select('md.modelID,md.model_photo') - > from('model md');
        $this - > db - > where(array('md.active' = > 1, 'md.modelID' = > $model_selected));
    }
    $query = $this - > db - > get();
    $photos = array();
    if ($query - > result()) {
        foreach($query - > result() as $photo) {
            $photos[$photo - > modelID] = $photo - > model_photo;
        }
        return $photos;
    } else {
        return FALSE;
    }
    $query - > result();
    return $query - > result();
}

这是我的控制器：

function base_photo($selected_car){
    header('Content-Type: application/x-json; charset=utf-8');
    echo(json_encode($this->config_model->get_base_photo($selected_car)));
}

这是我的jquery：

$.ajax({
    type: "POST",
    url: base_url + "configurator/base_photo/" + modelID,
    success: function (response) {
        $.each(response, function (id, name) {
            alert('name');
            $("‪#‎photo‬").attr("src", base_url + "assets/img/wheels/" + name);
        });
    },
    error: function () {
        alert('error document ready photos');
    }
});  

这是我的html

<div id="top">
<?php echo form_open('configurator/index'); ?>
<select id="model_selected" name="model_selected">
<?php
foreach($cars as $car){
if(isset($_POST['model_selected']) && $_POST['model_selected'] == $car->modelID){
    echo '<option value = '.$car->modelID.' selected>'.$car->modelName.' - '.$car->model_photo.'</option>';
}
else
{
    echo '<option value = '.$car->modelID.'>'.$car->makeName.' - '.$car->modelName.' </option>';
}
} 
echo form_submit('car_submit','submit'); 
?>
</select>

虽然它适用于某些modelID的图片，但在img src中有些返回未定义。然而，所有警报都使用正确的“名称”，但图片不会出现……请帮助？

似乎还有另一行冗余代码在做类似的事情，即更改#photo src，这使得它有时工作，有时不工作

Id在html中是唯一的。#照片Id是重复的，我想显示你正确的html代码hi@JqueryKing我已经编辑了代码来添加html代码。我做错了什么？上面的代码在firefox中工作，但有时在chrome中返回未定义的
