Using [jQuery](http://en.wikipedia.org/wiki/JQuery), how can I dynamically set the size attribute of a select box?

I would like to include it in this code:

```
$("#mySelect").bind("click",
    function() {
        $("#myOtherSelect").children().remove();
        var options = '' ;
        for (var i = 0; i < myArray[this.value].length; i++) {
            options += '<option value="' + myArray[this.value][i] + '">' + myArray[this.value][i] + '</option>';
        }
        $("#myOtherSelect").html(options).attr [... use myArray[this.value].length here ...];
    });
});

```
