Question

I am passing a JSON object and an array to a Javascript function, but the array acts empty when I alert it unless I alert a specific value.

function myFunction(jsonObj, array){
    alert(array['item1']['name']);    //alerts "item1"
    alert(array);                     // alerts "" (not [object] as I'd expect)
    alert(array.join(''));            // alerts ""
}

What am I missing?

I’m developing with phonegap on xcode and also using jQuery and Jquery Mobile

Seems like you are using an array with string indexes. That won’t work well:

> var array = [];
> array['foo'] = 'bar';
> array.length
0

Use an object instead:

var obj = {};
obj['foo'] = 'bar';

Use arrays only with numeric indexes.
