var obj = jQuery.parseJSON('{"name":"John"}'); alert( obj.query.results.quote );
得到一个对象。
您还可以声明一个名为function cbfunc(o){} eval() ，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。 🙂
jquery有一个方法
您发布的内容看起来像带有回调函数的JSON响应。
不知道你如何处理响应我会假设调用“cbfunc”函数。
function cbfunc(response){ var oResponse = jQuery.parseJSON(response); //Get the 1st quote in the array var quote1 = oResponse.query.results.quote[0]; }
