我对json相当新,我很难弄清楚如何解析特定的json响应。我在这个主题中搜索了很多,但我没有找到任何套件或适用于我的情况。因此,我知道它看起来像是重复的。
首先让我描述一下我的情景。
我有一个Mysql表
表格结构
mysql> describe faculty;
+-----------------------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-----------------------+-------------+------+-----+---------+-------+
| faculty_id | varchar(8) | NO | PRI | NULL | |
| faculty_name | text | NO | | NULL | |
| department_id | varchar(8) | YES | MUL | NULL | |
| department_name | text | NO | | NULL | |
| profile_pic | text | NO | | NULL | |
| designation | text | NO | | NULL | |
| doj | date | NO | | NULL | |
| email | text | NO | | NULL | |
| highest_qualification | varchar(10) | YES | | NULL | |
| industrial_exp_yr | smallint(6) | YES | | NULL | |
| industrial_exp_month | smallint(6) | YES | | NULL | |
| teaching_exp_yr | smallint(6) | YES | | NULL | |
| teaching_exp_month | smallint(6) | YES | | NULL | |
| area_of_interest | text | NO | | NULL | |
| national_pub | smallint(6) | YES | | NULL | |
| international_pub | smallint(6) | YES | | NULL | |
+-----------------------+-------------+------+-----+---------+-------+
16 rows in set (0.01 sec)
我的JS:
$("#up_dept").change(function() {
var dept = $('#up_dept option:selected').text();
$.ajax({
url: "proc/get_flist.php",
type: "POST",
data: {
dept: dept
},
dataType: "json",
async: true,
cache: false,
success: function(response) {
// Tried naive forloop
// JSON.Parse
// Nothing worked so kept blank
}
});
});
PHP
$fac = new Faculty();
$dept = trim($_POST["dept"]);
$facul_list = $fac->faculty_list($dept);
echo json_encode($facul_list);
faculty_list功能
function faculty_list($dept_name) {
try {
$db = new PDO(DB_CONN, DB_USER, DB_PASS);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$query = "select * from faculty where department_name ='" . $dept_name . "';";
$stmt = $db->query($query);
if ($stmt->rowCount() > 0) {
$list = $stmt->fetchAll();
$db = null;
return $list;
} else {
return "NULL";
}
} catch (PDOException $ex) {
echo $ex->getMessage();
//utils::log_error($ex -> getMessage());
}
}

现在,我需要能够console.log响应的每个字段 说,
response.faculty_id [0];
请帮我解决这个问题。我不太确定响应是否是有效的json。
答案 0 :(得分:5)
response
是一个数组,你需要循环它。
success: function(response) {
$.each(response, function(index, data) {
console.log(data.faculty_id);
});
// get the first one only
console.log(response[0], response[0].faculty_id);
}
答案 1 :(得分:0)
只需用
替换此行return $list;
这一个
return json_encode($list);
你的问题应该解决了!
答案 2 :(得分:-1)
试试这个
var json_resp = jQuery.parseJSON(response); 的console.log(json_resp [0] .faculty_id)
