我有下面的代碼在PHP:jQuery的成功不會在代碼觸發200
$servername = "***";
$username = "***";
$password = "***";
$dbname = "***";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "select * from `opencartdb`.`oc_design` where name='mydesign '";
$res=$conn->query($sql);
$records=$res->fetch_assoc();//success
$result2=$records['info'];// already json
$conn->close();
echo ($result2);
,我嘗試用下一個JS抓住它:
jQuery.ajax({
dataType: "json",
url: "ajax.php?type=loadDesign&user_id="+user_id+"&design_id="+key
}).success(function(data) {
alert(0);
console.log((data));
}).always(function(){
alert(1);
});
最終我看到警告1 德布格向我展示了下一個結果。迴應:

此行是畫在debugge:

呀'報頭( '內容類型:應用/ JSON;字符集= UTF-8');'是幫助,但我在我的json中也發現錯誤$ result2 = str_replace(''{','{',$ result2); \t \t $ result2 = str_replace('}「','}',$ result2);'解決它。 '「vectors」:「{」front「:' – tttaaabbb
如果您的json無效,我建議使用json_encode,如果它幫助您解決問題,請將其設置爲正確。 –
