I also try the json_encode and the data that i m getting on success is

{"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"}]}

Now how i can get the values against q_id 83

[pritaeas]

Most likely:

data['o'][0]
//or
data[0]

I also try this but error is Uncaught TypeError: Cannot read property '0' of undefined

now what should i do
