我想通过name
输出这个PHP代码echo star_type
,service
,jquery.each()
,但我有错误。如何解决?
错误:
发生错误:
[object object]
parsererror
SyntaxError:JSON.parse:后面的意外非空白字符 JSON数据
我有这个PHP代码:
//$hotel_id = $this->input->post('hotel_id');
$hotel_id = array('1','2','3');
//print_r($hotel_id);
foreach ($hotel_id as $val) {
$query_r = $this->db->query("SELECT * FROM hotel_submits WHERE id LIKE '$val' ORDER BY id desc");
$data = array();
foreach ($query_r->result() as $row) {
$data_s = json_decode($row->service, true);
$data_rp = json_decode($row->address, true);
$data[] = array(
'name' => $row->name,
'star_type' => $row->star . '-' . $row->type,
'site' => $row->site,
'service' => $data_s,
'address' => $row->address
);
}
echo json_encode($data);
}
这是PHP代码上面的输出:
[{
"name": "how",
"star_type": "5-hotel",
"site": "www.sasaas.assa",
"service": ["shalo", "jikh", "gjhd", "saed", "saff", "fcds"]"address": "chara bia paeen"
}][{
"name": "hello",
"star_type": "4-motel",
"site": "www.sasasa.asas",
"service": ["koko", "sili", "solo", "lilo"]"address": "haminja kilo nab"
}][{
"name": "hi",
"star_type": "3-apparteman",
"site": "www.saassaas.aas",
"service": ["tv", "wan", "hamam", "kolas"],
"address": "ok"
}]
这是我的js代码得到错误:
$.ajax({
type: "POST",
dataType: "json",
url: 'get_residence',
data: dataString_h,
cache: false,
success: function (respond) {
//alert(respond);
$.each(respond[0].name, function (index, value) {
alert(value);
});
},
"error": function (x, y, z) {
alert("An error has occured:\n" + x + "\n" + y + "\n" + z);
}
});

你没有回应有效的json。试试这个:
$hotel_data = array();
foreach(...) {
// .. do stuff
$hotel_data[] = $data; // add $data to the end of the $hotel_data array
}
echo json_encode(array('data' => $hotel_data));
这会将所有$data
数组包装到一个数组中,并将其放入对象的数据属性中。您可以按如下方式在js端访问此数据:
$.each(response.data, function(i, obj) {
alert(obj.name);
});
注意:我不确定我上面写的php语法,自从我写php以来已经有一段时间了:)

你的php输出无效json,你错过了"address"
之前的逗号。
您可以使用此网址检查您的json:http://json.parser.online.fr/

您的JSOn完全无效。你不应该在循环中回显json-ecnoded数组,而是在它之外:
$all_data = array();
foreach ($hotel_id as $val) {
//..what you have there now, but instead if echo json_encode($data); you do
$all_data[] = $data;
}
//and finally
echo json_encode('data'=>$all_data);
