我在访问对象中的对象时遇到问题。你能告诉我一些信息吗？

我想做类似的事情：

 alert(text.responseData['results'])

谢谢

将此text json对象粘贴到chrome的控制台中。并尝试访问text变量。它会自动完成并帮助您找到变量内部对象的路径。这就是我对json对象所做的。对于start变量，请尝试使用此代码。

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

在对象中打印对象
