Convert JSON string to function parameters

I have a string of javascript objects that I need to convert to function arguments.

The string looks like this:

"{ "item1": "foo 1", "item2": "bar 1" }, { "item1": "foo 1", "item2": "bar 2" }"

I can concat "[ ]" and call JSON.parse to turn it into a valid array however, this does not solve my problem since the function needs them to be separate objects not an array of objects.

EX:

functionCall({ "item1": "foo 1", "item2": "bar 1" }, { "item1": "foo 1", "item2": "bar 2" });

I will never know how many objects will be in this string so I do not know how many arguments the function should accept either.

I would love to be able to add multiple objects to one variable like:

var objects = { "item1": "foo 1", "item2": "bar 1" }, { "item1": "foo 1", "item2": "bar 2" }

and then I could just call

functionCall(objects);

Is there a way to accomplish something like this or another approach I can take?
