How to change Key of an object dynamically

Question

I have an object like this:

var obj{};

I want to set object values dynamically like so:

for(i=0;i<10;i++) { quest='quest'+i; header='header'+i; $(obj).data(quest,{header:i}); quest,header=0; }

I'm expecting object to be saved like:

obj{quest1:{header1:1}, quest2:{header2:2} quest3:{header3:3}

But they are saved like:

obj{quest1:{header:1}, quest2:{header:2}, quest3:{header:3},

The header-key in my object is not getting the actual value. but simply save as "header"..

Could you please guide me here?

You can write:

var obj = {}; for(i=1; i<11; i++) { quest='quest'+i; header='header'+i; obj[quest] = {}; obj[quest][header] = i; }

In your code your loop starts with i = 0 but the properties start by 1.

var quest, header, obj = {}; for (i = 0; i < 10; i += 1) { quest = 'quest' + (i + 1); header = 'header' + (i + 1); obj[quest] = {}; obj[quest][header] = (i + 1); }

You cannot have a variable key in an object literal.
