Problem with multidimensionnal JSON object

Roger (Bordeaux)

Hello,

You will find behind an example of the problem.

The defined JSON object is multidimentinnal.

The "weeks" object contains a serie of dates with week number and
monday's date.

I want to write a loop to display the dates. But the alert(typeof(b))
answer 'string' in place of 'object' and I can't access to the dates.

What's wrong ??

Thanks in advance for your help.

Roger

var jsonObject =
{"2":{"name":"Xavier","weeks":{"01":{"date":"20 06-01-02"},"02":{"date":"2006-01-09"}}}};

for (a in jsonObject) {

alert(Object.display(jsonObject[a].weeks));

for (b in jsonObject[a].weeks) {
alert(typeof(b));
}
}

for..in enumerates the property names which are always strings so there
is nothing wrong with what you see. If you want the type of the property
value then you need to access e.g.
alert(typeof(jsonObject[a].weeks[b]));
