ajax.js

$(document).ready(function(){ 
var sfield = $("#s");

     $url = $item->link; 

     $images[] = array(
     "src" => htmlspecialchars($src), 
     "thumb" => htmlspecialchars($thumb), 
     "url" => htmlspecialchars($url) 
     ); 

    } 
} 

print_r(str_replace('\\/', '/', json_encode($images))); 
die(); 
?>

我需要通過標籤搜索的Instagram照片。但是，Ajax請求返回parseError和未捕獲的SyntaxError：意外的標記：」

我希望你能幫助我

非常感謝

您可以在json_encode之前打印$圖像嗎？ – deb0rian

你不應該提到你期待json作爲響應的地方嗎？ –

@Fratyr是的。 echo $ imagenes Array []。 $ imagenes [0]爲空，結果爲[] – Litox

嘗試添加：

dataType:'JSON'

到$阿賈克斯通話，例如

$.ajax({    
dataType:'JSON', 
type: 'POST', 
...

不起作用！ – Litox

我已測試過您的代碼，它適用於我，有和沒有具體的數據類型參數的唯一問題是，在你的PHP代碼，你有回聲$響應; 這是造成問題，你缺少一個}之前 clearTimeout（定時器）在你的JavaScript –
