JsFileInfo

This lets you iterate every available tag in a handle without knowing their name in advance.

Example

var handle = fb.GetFocusItem();

var obj = {};
var f = handle.GetFileInfo();

for (var i = 0; i < f.MetaCount; i++) {
    var name = f.MetaName(i).toUpperCase();
    obj[name] = [];

    var num = f.MetaValueCount(i);
    for (var j = 0; j < num; j++) {
        obj[name].push(f.MetaValue(i, j));
    }
}

console.log(JSON.stringify(obj, null, 4));
