Answer 1

jqueryのは、JSONがないあなたが持っている

http://api.jquery.com/jQuery.parseJSON/

Answer 2

ための方法があります。パディング付きのJSONです。 JSONとして解析できるようにするには、 "cbfunc（"および "ending"）を削除する必要があります。次に、使用することができます：

var obj = jQuery.parseJSON('{"name":"John"}'); 
alert(obj.query.results.quote); 

オブジェクトを戻すには。

function cbfunc(o){}という関数を宣言してから、文字列の周りにeval()という名前を付けることもできますが、これはおそらく最も安全な方法ではありません。 :)

Answer 3

投稿した内容は、コールバック機能を備えたJSONレスポンスのようです。

どのように応答を処理しているのかわからないので、「cbfunc」関数が呼び出されると仮定します。

function cbfunc(response){ 

var oResponse = jQuery.parseJSON(response); 

//Get the 1st quote in the array 
var quote1 = oResponse.query.results.quote[0]; 

}
