Question: What is the best way to convert the string values to an int array, e.g.:

```
var s = '1,1,2';

```

to:

```
var a = [1,1,2];

```

Thanks

Answer: 
JavaScript is a dynamic-typed language, which means that it might not be so important for those array items to be numbers. If that's the case, you might want to consider just using `split()`:

```
var s = '1,1,2',
    a = s.split(",");

```

If it is important that they're numbers, then your best bet is to iterate over them afterwards:

```
for (var i = 0, max = a.length; i < max; i++)
    a[i] = +a[i]; 

```

There's also the ECMAScript 5th Edition method `map`, but it's not implemented in all browsers yet.
*If the data is secure*, you could use `.eval()`.

```
var a = eval( '[' + s + ']');

```

If you're not sure about security, you could use `JSON.parse`.

```
var a = JSON.parse( "[" + s + "]" );

```

...though you'll need to include a parser in browsers that don't support it natively.
