推荐答案
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：
What you have there is not JSON. It's JSON with padding. You have to remove "cbfunc(" and the ending ")" to be able to parse it as JSON. Then you can use:
var obj = jQuery.parseJSON('{"name":"John"}');
alert( obj.query.results.quote );
获取对象。
您还可以声明一个名为的函数cbfunc（o）{} 然后只需执行 eval（）围绕你的字符串，但这可能不是最安全的方法。 ：）
You can also declare a function called function cbfunc(o){} and then just do eval() around your string but this is probably not the safest way. :)
