javascript - traverse dynamic number of options in json array -

-

i building mcq application has multiple questions varying number of options. so, question 1 can have 4 options , question 2 can have 2 options , on.

i have generated json array backend gives me data tells me number of options each question has.

but stuck on part of displaying options on browser.

my json object looks this:

[ {     "option1": "asdasd",     "option2": "ajda",     "option3": "hsadb",     "option4": "asd",     "question": "hello",     "quest_id": 32 }, {     "option1": "dsf",     "option2": "afs",     "question": "asdad",     "quest_id": 34 } ]

i want display dynamically each question corresponding options , radio buttons besides them.

also have array tells me number of options in each [4,2] says question 1 has 4 options , question 2 has 2 options. tried apply ng-repeat using angular js in array gives "dupes error" duplicate elements not allowed. appreciated. in advance.

{test:[{question: "hello", answers:['asda','asdasd','asdasd'], "quest_id": 32}]} use structure , ng-repeat should this.

<div ng-repeat="question in test"> {{question.question}} <div ng-repeat="obj in question.answers">   <input type="radio" ng-model="testresult[question.quest_id].answer" value="obj"> </div>

something should work
