Mutidimensional Array Of Checkboxes?

Accepted Answer

Well it is possible to select a specific checkbox.

You can select on the name attribute `question[x][]` then loop through those to get each of their checked values.

An example using jQuery:

```
var checkedBoxes = {0: [], 1: [], 2: []};
$("input[name='question[0][]']").each(function(){
    checkedBoxes[0].push(this.checked);
});
//then do the same for 1 and 2

//after everything:
console.log(checkedBoxes); //a multidimesional array of checked boxes
```

Or to make it even fancier:

```
var checkedBoxes = {0: [], 1: [], 2: []};
for(index in checkedBoxes) {
    $("input[name='question[" + index + "][]']").each(function(){
        checkedBoxes[index].push(this.checked);
    });
}
//after everything:
console.log(checkedBoxes); //a multidimesional array of checked boxes
```
