How to copy javascript object to another object?

Question

Let's say I want to start with an empty JavaScript object:

me = {};

And then I have an array:

me_arr = new Array();
me_arr['name'] = "Josh K";
me_arr['firstname'] = "Josh";

Now I want to throw this array into an object so that I can use me.nameto return Josh K.

I tried:

for(var i in me_arr)
{
    me.i = me_arr[i];
}

But this did not have the desired result. Is it possible? My main goal is to wrap this array in a JavaScript object so that I can pass it to a PHP script (via AJAX or something else) as JSON.

Answer 1

Since the property name is also a variable, the loop should look like this:

for(var i in me_arr)
{
    me[i] = me_arr[i];
}

You should check JSON in JavaScript . There is a JSON library download that can help you create JSON objects.

Answer 8

Why don't you just do:

me['name'] = "Josh K";
me['firstname'] = "Josh";

?
This is the same as

me.name = "Josh K";
me.firstname = "Josh";
