Question

A basic question please, I am trying this code:

var number_questions = postsJSON1[i]['question'].length;
for (a=0; a<number_questions; a++) {
var post+[a] = postsJSON1[i]['question'][a];    
}

this line give an error: var post+[a]

What is the correct way ?

Answer 1

This will get you an array:

var number_questions = postsJSON1[i]['question'];
var post = [];
for (a=0; a<number_questions; a++) {
  post[a] = postsJSON1[i]['question'][a];    
}

This will get you a string:

var number_questions = postsJSON1[i]['question'];
var post = '';
for (a=0; a<number_questions; a++) {
  post += postsJSON1[i]['question'][a];    
}

BTW I don’t know the contents of postsJSON1[i]['question'], but the following looks a bit weird:

var number_questions = postsJSON1[i]['question'];

Shouldn’t that be:

var number_questions = postsJSON1[i]['question'].length;

?
