javascript中無法解析Json數據----學生數據(Key)和數據(Key)

Question

我無法使用 javascript 解析這些數據，我想要動態的 studentdata 和 question 數據......

代碼：

{
    "studentdata": "[{\"studentid\":3,\"attemptid\":\"724\",\"tokenid\":\"dc049c8429af5ec2b8e7fe8a0b20d4a3\"}]",
    "quizid": "5",
    "tap": false,
    "body": "",
    "data": "[{\"question\":\"If a and b are negative numbers, and b - a is negative\",\"options\":[\"True\",\"False\"],\"answer\":[true,false]},{\"question\":\"The equation 2x 7 \u003d 2(x 5) has one solution\",\"options\":[\"True\",\"False\"],\"answer\":[false,true]},{\"question\":\"If f(x)\u003dsqrt(1-x), then f(-3)\u003d2\",\"options\":[\"True\",\"False\"],\"answer\":[true,false]},{\"question\":\"The reciprocal of 0 is equal to 0\",\"options\":[\"True\",\"False\"],\"answer\":[false,true]},{\"question\":\"The additive inverse of -10 is equal to 10\",\"options\":[\"True\",\"False\"],\"answer\":[true,false]}]",
    "title": "Quiz"
}

任何幫助或建議將不勝感激。

謝謝 -
