我正在使用 codeigniter 框架来开发我的网站。目前我正在使用 jQuery 发送 AJAX 请求以从服务器获取数据。我尝试了两种方法,一种是数据在 PHP 关联数组中,另一种是在 JSON 对象中。请查看我从 AJAX 请求返回的数据:
{
"o": [
{
"q_id": "83",
"t_id": "4",
"question": "jjjjs.jfdaskldjf",
"option1": "jjjjasdfasdf",
"option2": "jjj",
"option3": "lll",
"option4": "lll",
"answer": "lll",
"marks": "22"
},
{
"q_id": "84",
"t_id": "4",
"question": "This is testing",
"option1": "2",
"option2": "7",
"option3": "8",
"option4": "9",
"answer": "2",
"marks": "2"
},
{
"q_id": "85",
"t_id": "4",
"question": "hello this is another test",
"option1": "a",
"option2": "b",
"option3": "c",
"option4": "d",
"answer": "a",
"marks": "2"
},
{
"q_id": "86",
"t_id": "4",
"question": "another test",
"option1": "8",
"option2": "9",
"option3": "0",
"option4": "1",
"answer": "1",
"marks": "2"
},
{
"q_id": "87",
"t_id": "4",
"question": "last question ",
"option1": "z",
"option2": "x",
"option3": "c",
"option4": "v",
"answer": "c",
"marks": "2"
}
]
}
我以以下方式访问它:
alert(data["o"][0]);
但是发生的错误是:
未捕获的类型错误:无法读取未定义的属性“0”
谁能给我一些关于如何获取值或将对象存储在数组中的建议。
