你好，也许是愚蠢的问题，但我如何打印例如从这个开始

        "searchResultTime": "0.20"
    }
},
"responseDetails": null,
"responseStatus": 200

}

我在访问对象中的对象时遇到问题。你能给我一些信息吗？

我想做类似的事情：

 alert(text.responseData['results'])

谢谢

Paste this text json object in chrome's console. And try accessing text variable. It will auto complete and help you find the path to the objects inside the variable, you desire. That's what I do to json objects. For your start variable try this code. 

var pages = text.responseData.cursor.pages;
for(var i=0; i < pages.length; i++){
   console.log(pages[i].start)
}
