How to convert this string to an array

Question

I need to convert this string to an array:

var mystring = "[-item1,item2]";

This is handed to me as a string. Is there a javascript function that can convert this? If not how would you suggest putting item1 and item2 in an array?

Are `item1` and `item2` variables or are they actual values embedded in the string (e.g. `[-5, 7]`)? — p.s.w.g, Sep 07 '14 at 04:23
You want the literal string "item1", "item2" in an array? or the variables? If the latter, what scope are they in? — Chad Grant, Sep 07 '14 at 04:23

@Luke101 - Converting from what? Are `item1` and `item2` variable names or strings? — Derek 朕會功夫, Sep 07 '14 at 05:07
So you're given the string `'[-item1,item2]'`. But what is it supposed to convert _to_? What is the resulting array supposed to look like? — flowstoneknight, Sep 07 '14 at 05:27

Maybe you can use the split() Method:

I would first remove the first and last character in order to get rid of the "[" and"]"

then:

var str = "-item1,item2";
var res = str.split(",");

The result of res will be an array with the values:

[-item1,item2]

If text1 and text2 are not var's but literal's you will need to add quotes.
Use JSON.parse to create objects from strings:

var numbers = '[-1,2]';
var mystring = '["text1","text2"]';
var numbersArr = JSON.parse(numbers);
var stringsArr = JSON.parse(mystring);
console.log(numbersArr);
console.log(stringsArr);

JSFIDDLE.
