Try this:

function joinObjects( array ) {

    // Start with empty array
    var ret = new Array();

    // Iterate array
    for ( var i = 0; i < array.length; i++ ) {

        // Search by fieldname
        var match = false;
        var j;
        for ( j = 0; j < ret.length; j++ ) {
            if ( array[i].Fieldname == ret[j].Fieldname ) { match = true; break; }
        }

        // If not exists
        if ( !match ) {

            // Intert object
            ret.push({
                Fieldname: array[i].Fieldname,
                Value: new Array()
            });

        }

        // Insert value
        ret[j].Value.push( array[i].Value );

    }

    // Return new array
    return ret;

}
