how to set values dynamically to javascript var

Question

i've a requirement to set the values dynamically into js var, which i will use it to set to sapui5 model .

but i'm unable to do that. http://jsbin.com/fubobuvoqi/1/edit?html,console here, i'm unable to set next value into the array:

data.a.b.c[1].c1 = "234";
console.log(data.a.b.c[1].c1);

is it possible do that way, or its completely wrong way of doing it.. what is best way of doing this?

i want to grow my c array dynamically.

Answer 1

You cannot assing it, cause it's really doesn't exist yet (undefined), but you can create it using push() try to change

data.a.b.c[1].c1 = "234";

to

data.a.b.c.push({c1: "234"});

this will add one more element to array and make you var look like

  c : [
    {
      c1 : "987",
      c2 : 987,
      c3 : "987.00"
    },
    {
      c1 : "234"
    }
  ]
