答案 0 :(得分：2)
你所拥有的不是JSON。它是带填充的JSON。您必须删除“cbfunc（”和结尾“）”才能将其解析为JSON。然后你可以使用：
var obj = jQuery.parseJSON('{"name":"John"}');
alert( obj.query.results.quote );
获取一个对象。
您还可以声明一个名为function cbfunc(o){}的函数，然后在您的字符串周围执行eval()，但这可能不是最安全的方法。 ：）
答案 1 :(得分：0)
jquery有一个方法
答案 2 :(得分：0)
您发布的内容看起来像是带有回调函数的JSON响应。
不知道你是如何处理响应我假设“cbfunc”函数被调用。
function cbfunc(response){
var oResponse = jQuery.parseJSON(response);
//Get the 1st quote in the array
var quote1 = oResponse.query.results.quote[0];
}
