get next item in json string array

Question

I have a loop that loops through each item in an array and populates a check box.

the identity alternates throughout the loop.

"[{\"NAME\":\"TOM, B\",\"ID\":\"222\"},{\"NAME\":\"joe\",\"ID\":\"202\"}]"

how can I get the text of the select box to be the ID and the Name to be the text.

$.each($.parseJSON(json), function () {               
   $.each(this, function (key, value) {
     drname.options.add(new Option(value, value[+1])); 
    });
});

I tried the [+1] as I've seen in similar questions but no dice.

thanks.

There is no need for that second $.each, just use the properties of the object directly without iterating through them:

$.each($.parseJSON(json), function(){               
    drname.options.add(new Option(this.ID, this.NAME)); 
});

Depending on what order the Option constructor expects the argument, it could also be:

new Option(this.NAME, this.ID)

Thank you. A point worth mentioning... every time this function is called the options are appended to the list. For a second I thought something was wrong because my select box was three times longer than I expected. But that was only because I called the function three times. I used $("selectBoxName").empty() before the function to clear the options of the select box because in my situation the function may be called more than once with a json array.
